Uroscopy is the first documented laboratory test in medicine and is a fundamental diagnostic tool in the Unani system of medicine. Proper sample collection, handling, and identification are important to insure valid results in uroscopy.There are certain do’s and don’ts about the sampling mentioned in the text of the Unani medicine that should be followed. Generally, a urine sample is collected by the patient himself or herself, hence they must be educated to avoid contamination to ensure the purity of the sample. Despite this, there is a chance for error or malpractice hence collected samples should be identified for sufficiency and originality. There is a certain factor that can cause an erroneous result that must be avoided. Unani scholars have mentioned that sometimes patients brought other similar fluids or animal urine to test the competence of the physician or to mislead the diagnosis. To deal with such a situation differentiation of urine with other liquors should be made. The method of sample collection and identification for uroscopy are systematically summarized in this paper.

Dermatophytosis affect companion animal’s skin and keratin appendages as cats and dogs, resulting in red, scaly, itchy, bald, and raised patches like ring. The three main groups are Microsporum, Trichophyton and Epidermophyton. This study collected samples of skin scrapping and hairs from 130 cats and 70 dogs, using common mycological approach samples were examined. Antifungal agar disc diffusion and broth microdilution assays were utilized on some of the isolates. Three groups of Guinea pigs (6 in each) were then infected with one isolate of M. canis or T. mentagrophytes fungi, another skin scrapping samples of virulent fungi was isolated on the 7th and 14th days, blood samples were collected at 14th day. Reverse transcription-PCR to detect 98 bp protease gene. Resulting in 45% of cats and dogs tested positive for Microsporum and Trichophyton species. Agar disc diffusion revealed that the antifungal medication griseofulvin was the most effective against tested isolates. The best results for MIC test were griseofulvin (0.98 µg/ml) followed by acetic acid (0.28 µg/ml). Differential leukocytic count of Guinea pigs showed that monocyte levels remained unchanged, while neutrophil and lymphocyte levels had increased. The active (isolates from Guinea pigs skin scrapping) and dormant cells (isolates from keratin free media) were distinguished by Reverse Transcriptase-PCR. Collectively, qPCR is a successive and feasible method for the diagnosis for Microsporum and Trichophyton species.

Bacteria of the genus Staphylococcus are pathogenic Gram-positive bacteria responsible for various infections, including skin suppuration, which can be severe or chronic. The objective of this study was to confirm Staphylococci strain’s identification isolated by bacteriological methods from biological products of CHU-B patients, by molecular methods based on the analysis of the gene coding for 16S rRNA. In total, 30 strains of Staphylococci were isolated including 8 (26.66%) community strains, 22 (73.33%) hospital strains. The products of the amplification of gene fragments encoding 16S rRNA from 10 strains of Staphylococci including 6 strains of Staphylococcus aureus (S. aureus) and 4 Coagulase Negative Staphylococci (CNS) were sequenced. The sequences obtained were subjected to bioinformatics analysis to confirm the results of conventional bacteriological methods. Six (6) S. aureus strains, 2 Staphylococcus haemolyticus strains, 1 uncultured bacterium clone nbw618g09c1, and one Staphylococcus sp. have been identified. These results made it possible to confirm the effectiveness of the molecular method and to show the limits of traditional bacteriological methods in the complete identification of bacteria.

Fingerprints are commonly used for identification 1. All records are computerized. In a catastrophe recorded images of soft tissue may become useless if the tissues burn throughout. Dental prints are rarely used for identification. Information is taken from dental radiographs or dental casts. In case of fire recorded images of dental structures may be useful because they do not readily burn.

In recent years, the consumption of dietary supplements (DS) has increased worldwide. In Argentina, approximately 14 million DS units were sold between 2015 and 2017. The adulteration of DS with active pharmaceutical ingredients or their analogues has been reported. This represents an alarming emerging risk to public health. The aim of this work was to detect the possible adulteration of a DS marketed in Argentina for the treatment of erectile dysfunction. Initially, thin layer chromatography analysis of the DS capsules content suggested the presence of a major compound. For the isolation and purification of this compound, an easy method consisted of a liquid-liquid extraction (water/CH2Cl2) followed by re-crystallisation from ethanol, is reported. Spectroscopic techniques such as mono- and bidimensional nuclear magnetic resonance, Fourier transform infrared spectroscopy and mass spectrometry allowed its identification as tadalafil. A rapid and reliable method was developed for the quantification of tadalafil in this DS by high performance liquid chromatography-mass spectrometry (HPLC-MS/MS). The mean content of tadalafil per capsule was 21.2 mg which represents a slightly higher value than that found in approved products in Argentina (5 or 20 mg per tablet). In addition, an undeclared alga was identified in the DS by microscopic techniques.

Objective: The aim of the present study is to determine the efficiency of third year ophthalmology residents from a tertiary hospital in performing preliminary retinal examination to identify eyes at risk retinopathy of prematurity on the basis of retinal fundus findings up to International Classification of Retinopathy of Prematurity (ICROP) Zone II. Methods: This is a single-center, cross-sectional, prospective comparative research conducted from June to October 2015 at a tertiary training hospital in the Philippines. All infants referred for retinopathy of prematurity screening within the study period where included. The presence of retinal vessel dilatation and tortuosity were identified by third year ophthalmology residents using indirect funduscopy. The residents’ fundus findings were then compared to that of a retina consultant who is proficient in the diagnosis and management of retinopathy of prematurity (ROP). The Kappa index was used to rate inter-observer agreement. The correlation between ROP risk factors and the presence of abnormal retinal vessels were assessed using odd ratio computations. Fisher’s exact test was used to determine the correlation between retinopathy of prematurity and the presence of retinal dilatation and tortuosity. The McNemar’s test was also applied to determine significant differences in the retinal findings of the consultant and ophthalmology residents. Results: A total of 82 eyes of 41 premature infants were evaluated to determine if retinal findings observed by ophthalmology residents were comparable to that of a retina consultant. Odds ratios show that age of gestation, birth weight, and history of blood transfusion are significantly associated with the presence of retinopathy of prematurity. Retinal vessel tortuosity and dilatation are also more common among infants diagnosed with retinopathy of prematurity. There was no significant difference between the retinal vascular findings of the retina consultant and the third year ophthalmology resident in terms of identifying retinal vessel dilatation and tortuosity (P < 0.05). Conclusion: After sufficient and in-depth ophthalmology training, third year ophthalmologists, who will be general ophthalmologists in the future, can reliably identify eyes at risk for severe retinopathy of prematurity on the basis of retinal vascular dilatation and/or tortuosity.

Estimates of the genetic diversity of Large Japanese field mouse Apodemusspeciosus populations and identification of their plant food resources were conducted in an industrial green space, where were constructed on reclaimed land and belonged to the Aichi Refinery of Idemitsu Kosan Co., Ltd., in Aichi Prefecture, Japan. A total of six mitochondrial D-loop haplotypes were identified in 50 mice. Habitat condition with the highest number of captured individuals had abundant broad-leaved trees and understory vegetation. A minimum spanning network, which did not form a ring-shaped network, revealed that the hereditary population structure was weak. The low genetic diversity observed in the study area was thus attributed to isolation from other populations once the population in the study area by sea and road, which is more than 30 m wide. In order to identify which plant food resources were utilized by mice captured inside the industrial green space, partial chloroplast rbcL sequences were amplified by PCR from DNA extracted from 43 feces samples. Calculations of sample completeness curve revealed that 25 of the taxa identified in this study comprised approximately 90% of the food plant resources in the study area. Of the 21 plant families identified from the obtained rbcL sequences, members of the Rosaceae (28.0%), Fagaceae (17.2%), Lauraceae (14.2%) and Oleaceae (7.7%) were dominant. To ensure the continued survival of A. speciosuspopulation in this industrial green space would be to preferentially conserve plant species that are used as food resources by this species.

Microorganisms are the main cause of food-borne illness in humans that may occur by consuming unhygienic products from poultry and other sources. With the passage of time bacterial resistance to antibiotics is ever-increasing which necessitates development of new antibiotics. One of the most obvious reasons of antimicrobial resistance in human-beings is the consumption of contaminated food with microbes. The aim of present study is to isolate, identify and characterize the food-borne pathogens from chicken eggs. For this purpose, a total of 240 egg samples were collected from eight different towns of Faisalabad. Samples were collected from egg surface, yolk, albumin and egg tray. Isolation, identification and characterization of commonly occurring egg borne pathogens including E. coli, Salmonella spp., Bacillus subtilis, Staphylococcus aureus were carried out by different cultural, morphological and biochemical tests. Antibiotic resistance pattern of recovered bacterial pathogens was determined by disk diffusion method (Kirby-Bauer). Zone of inhibition was measured through vernier calliper. The results revealed a high prevalence of Salmonella entitidis with 40.83% following Staphylococcus aureus with 22.08%, Escherichia coli with 17.92% and Bacillus subtilis in a lower ratio with 2.5%. The antibiotic sensitivity test showed different resistance patterns of the isolated microbes. For this purpose, five different drugs were used that included cefotaxime, tetracycline, gentamicin, levofloxacin and penicillin. Bacillus subtilis was highly resistant to penicillin and cefotaxime. Whereas, E. coli showed resistance to three antibiotics that were tetracycline, cefotaxime and penicillin. The only drug to which Staphylococcus aureus showed resistance was cefotaxime. Salmonella was resistant to tetracycline and gentamicin. The study concluded that chicken egg is contaminated with a number of bacteria that could be pathogenic or not. So, there is need of proper attention to cope up with possible future egg-borne illnesses.

An important use of proteomics data from Mass Spectrometry (MS) is the classification of tumor types with respect to peptides in specific cancer types. It is highly critical to find an optimal set of markers among specific cancer peptides whose expression can be clinically utilized to build assays for the diagnosis or to track the progression of specific cancer types. A number of feature selection algorithms have been proposed to obtain the classification of MS data. In this article, we proposed an improved feature selection algorithm based on feature weighting. Relief algorithm can calculate the weight of different features according to the correlation between their characteristics and categories. F-score is a simple filter-based feature selection method by evaluating how two sets of real numbers discriminate from each other. The main goal of this paper is to introduce a new feature weighting selection algorithm combining score from f-value and weight from relief, which is more accurate when classifying high-resolution MALDI-TOF (matrix-assisted laser desorption and ionization time-of-flight) MS data. We have developed a four-step strategy for data processing based on: (1) Align the study sets by binning of raw MS data, (2) local maximum search(LMS) peak detection, (3) a new combination feature weighting selection algorithm and (4) support vector machines achieve a satisfactory performance of identifying cancer and the healthy. The best parameter set for LMS were achieved with control variable method, which achieve an average accuracy of 97.4167% (sd = 0.0146) and the best accuracy of 98.6111% in 1000 independent 10 -fold cross validations.

Strawberry powdery mildew, caused by Podosphaeraaphanis is a major fungal disease that affects strawberry yield and quality. In the model plant species Arabidopsis and the crop plants barley, tomato and pea, the Mildew resistance locus O (MLO) proteins have been found to be required for powdery mildew susceptibility. The present study, based on the sequence of a wild plum (Prunus americana) MLO protein, identified 16 MLO genes within the genome of woodland strawberry, Fragaria vesca and examined their expression pattern in response to powdery mildew infection in three diploid strawberry cultivars. Phylogenetic analysis showed that the FvMLO genes can be classified into six clades. Four FvMLO genes were grouped into clade III, which comprises MLO genes from Arabidopsis, tomato and grapevine that mediate powdery mildew susceptibility. A RNA-seq analysis of two diploid strawberry cultivars, F. vescassp. vesca accession Hawaii 4 (HW) and F. vesca f. semperflorens line “Yellow Wonder 5AF7” (YW) at 1 d (1 DAI) and 8 d (8 DAI) after infection showed the expression of 12 out of the 16 FvMLO genes. The comparison of Fragments Per Kilobase of transcript per Million mapped reads (FPKM values) detected by RNA-seq and expression values of qRT-PCR for FvMLO genes showed substantial agreement. The FvMLO3 gene, which was grouped in clade III and orthologous to the Arabidopsis,tomato and grapevine genes, was highly expressed in YW compared to other FvMLO genes across varieties. The results showed that FvMLO genes can be used as potential candidates to engineer powdery mildew resistance in strawberry based on MLO suppression or genome editing.

Introduction. Obesity often coexists with insulin resistance, which is related to cardiometabolic risk. However, some obese individuals exhibit comparable insulin sensitivity (IS) to that of normal-weight subjects, a state associated with a reduced cardiometabolic risk. We aimed to determine the efficacy of a panel of surrogate markers of insulin sensitivity (IS) for the identification of insulin sensitive obese (ISO) vs. insulin resistant obese (IRO) with similar total fat mass (FM) and body mass index (BMI). Methods. This is a cross-sectional analysis among 144 overweight and obese post-menopausal women. IS was determined by the hyperinsulinemic-euglycemic clamp (HEC) and by surrogate indices such as Matsuda index, the simple index assessing insulin sensitivity using oral glucose tolerance test (SIisOGTT), Abdul-Ghani liver IS index, HOMA-IR and Abdul-Ghani muscle IR index. Results. When using upper and lower quartiles values or the median as cut-off for IS determined by the reference HEC to define ISO vs. IRO, Matsuda index, SIisOGTT and Abdul-Ghani indices classification identified ISO vs. IRO individuals with similar FM and BMI. With HOMA-IR, the two groups were similar for FM and had borderline significant difference in BMI. Using, receiver operating characteristic curves, Matsuda index AUC was similar to that of SIisOGTT and both indices AUCs were significantly higher than Abdul-Ghani indices AUCs. The best cut-off value for the Matsuda index was 2.5 (83.1% specificity, 54.2% sensitivity) and 0.25 for SIisOGTT (64.8% specificity, 70.8% sensitivity). Conclusion. Whole body IS indices, Matsuda and SIisOGTT indices seem to be reliable indices for the identification of ISO vs. IRO individuals.

Human uterine leiomyosarcoma (LMS) is neoplastic malignancy that typically arises in tissues of mesenchymal origin. The identification of novel molecular mechanism leading to human uterine LMS formation and the establishment of new therapies has been hampered by several critical points. We earlier reported that mice with a homozygous deficiency for proteasome beta subunit 9 (PSMB9)/b1i, an interferon (IFN)-g inducible factor, spontaneously develop uterine LMS. The use of research findings of the experiment with mouse model has been successful in increasing our knowledge and understanding of how alterations, in relevant oncogenic, tumour suppressive, and signaling pathways directly impact sarcomagenesis. The IFN-g pathway is important for control of tumour growth and invasion and, has been implicated in several malignant tumours. In this study, experiments with human tissues revealed a defective PSMB9/b1i expression in human uterine LMS that was traced to the IFN-g pathway and the specific effect of somatic mutations of Janus kinase (JAK1) molecule or promoter region on the transcriptional activation of PSMB9/b1i gene. Understanding the molecular mechanisms of human uterine LMS may lead to identification of new diagnostic candidates or therapeutic targets in human uterine LMS.

Sarcomas are neoplastic malignancies that typically arise in tissues of mesenchymal origin. The identification of novel molecular mechanisms leading to sarcoma formation and the establishment of new therapies has been hampered by several critical factors. Human uterine leiomyosarcoma (Ut-LMS) develops more frequently in the muscle tissue layer of the uterine body than in the uterine cervix. Although the development of gynecologic tumors is often correlated with the secretion of female hormones; that of human Ut-LMS does not and its risk factors remain unknown. Importantly, a diagnostic biomarker that can distinguish malignant Ut-LMS from benign tumor uterine leiomyoma (LMA) has yet to be established. Therefore the risk factor(s) associated with human Ut-LMS to establish a diagnosis and novel therapeutic method. Proteasome b-ring subunit LMP2/b1i-deficient mice spontaneously develop Ut-LMS, with a disease prevalence of ~40% by 14 months of age. We shown that LMP2/b1i expression was absent in human Ut-LMS, but present in other human uterine mesenchymal tumors including uterine LMA. Therefore, defective-LMP2/b1i expression may be one of the risk factors for human Ut-LMS. LMP2/b1i is a potential diagnostic biomarker for human Ut-LMS, and may be a targeted-molecule for a new therapeutic approach.

Background Acute diarrhea is the major cause of health public problem among paediatric patients in Tanzania. And in Low income countries (LICs), studies have shown, Acute watery Diarrhea (AWD) is the cause of morbidity and mortality which can be prevented by immediate identification and treatment of complications. Methods A prospective cohort study was done between December 2021 and April 2022 to determine the risks, complications, management strategies and predictors of mortality among paediatric patients ≤12 years of age with severe diarrhea. We excluded those who arrived in cardiac arrest at the Emergency Medicine Department (EMD) of Muhimbili National Hospital (MNH). Proportion was used to summarize the counts and frequency of participants who were at risk of complications and management strategies given and for predictors of outcomes. A Modified Poisson log linear model with a robust estimation test was used to test for significant associations between predictors and outcomes. Multivariate logistic regression was used to adjust for confounders. Results A total 6,570 paediatric patients presented to EMD during study period, and we recruited 144 (2.2%). The median age was 1 (IQR 0.7-2.0) years and most were male 86 (59.7%). Among the study participants with diarrhea, 120 (83.3%) had dehydration, acidosis 60 (42.3%), hypoglycemia 8 (5.6%), hypokalemia 76 (53.1%), and Acute renal failure 11 (7.6%). Those patients with complications received appropriate management, including IV crystalloid solution given to 131 (90.97%), and correction of acidosis 60 (42.3%), hypoglycemia correction with IV dextrose 10% 6 (4.2%), and hypokalemia and infections were corrected with IV potassium chloride 52 (36.1%) and IV antibiotic treatment 84 (58.3%) respectively. Conclusion Pediatric patients under 2 years of age are at high risk of severe diarrhea with dehydration as compared to other ages. Early referral and availability of point care tests are essential in early recognition of accompanied complications.

Background Ankle sprains are among the most common injuries in sports, often characterized by high recurrence rates despite appropriate local treatment. Traditional approaches primarily focus on the injured joint, with limited attention to proximal biomechanical factors that may predispose athletes to injury. Objective To propose a functional, longitudinal kinetic chain model in which sacroiliac joint dysfunction may act as a predisposing factor for ankle sprain/strain injuries in athletes. Methods This paper presents a clinical hypothesis based on biomechanical reasoning and observational findings. The proposed model describes how sacroiliac joint dysfunction, particularly posterior innominate rotation (PI), may lead to pelvic obliquity and functional leg length discrepancy. These changes may induce compensatory femoral external rotation and foot toe-out, altering ground contact mechanics during gait and running. Results (Hypothesis) The altered alignment and loading pattern may increase the vertical impact force and modify the ground reaction vector on the functionally shorter limb, resulting in reduced mechanical stability at the ankle during heel strike or foot contact. Over time, this may increase susceptibility to inversion or eversion injuries, manifesting clinically as recurrent sprain/strain. Conclusion Ankle sprains in athletes may, in some cases, represent the distal expression of a proximal biomechanical imbalance. Incorporating assessment of the sacroiliac joint and the longitudinal kinetic chain into routine clinical evaluation may improve injury risk identification and contribute to more effective prevention strategies. Further research is needed to investigate this proposed relationship.

Objective Diabetes poses significant public health challenges, with many individuals remaining undiagnosed and at risk of complications. This study aimed to evaluate the performance of decision tree ensemble methods for predicting diabetes onset using the Framingham Heart Study Teaching Dataset and to explore sex-specific risk patterns relevant to AI-driven interventions. Methods We analyzed data from 11,627 participants, incorporating demographics, vital signs, smoking status, medication use, and laboratory measures. Random Forest classifiers were developed to predict diabetes incidence at approximately 6-year (Period 2) and 12-year (Period 3) follow-ups. Class imbalance was addressed using undersampling, oversampling, and the Synthetic Minority Over-sampling Technique (SMOTE). Results The models demonstrated robust performance, achieving an Area Under the Curve (AUC) of 0.856 in Period 2, and moderate predictive ability in Period 3 (AUC = 0.732 in males, 0.786 in females). Key predictors included glucose level, BMI, systolic blood pressure, age, and heart rate. Notably, differences emerged in predictive accuracy between men and women, suggesting potential sex-specific vulnerabilities that merit further study. Conclusion Machine learning approaches, particularly Random Forests, show promise for medium- and long-term diabetes risk prediction, supporting early identification and intervention efforts. Future work should focus on hyperparameter tuning and explainability techniques, such as SHapley Additive exPlanations (SHAP) values, to improve model precision, interpretability, and fairness. Equity-focused strategies remain critical to ensure AI-driven tools benefit diverse populations and do not exacerbate existing disparities in diabetes care.

Background Prescribing appropriate analgesics with optimal dosages based on patients' pain severity is challenging, especially when multiple painkillers are involved. Tracking and analyzing the effectiveness of analgesics and their dosages over time is crucial for pain management. Existing systems lack the ability to integrate analgesic equivalent doses with temporal trends in pain scores, hindering effective decision-making. Methods We developed a Clinical Support System that calculates the daily oral morphine equivalent dose and analyzes trends in consumed equivalent doses of analgesics. The system provides a graphical user interface that displays medication prescriptions, actual medication usage, and pain scores. It offers features such as correlating analgesic drug usage with pain intensity, trend analysis of analgesic drug usage and pain intensity, and identification of effective oral morphine equivalent doses. Results The system overcomes previous barriers in drug analysis by providing real-time calculation of oral morphine equivalents and trend analysis of pain duration. It assists physicians in prescribing appropriate and safe medication dosages, enhancing medication safety for patients. Conclusions Our clinical support system offers a comprehensive solution for analyzing trends in consumed equivalent doses of analgesics. It integrates medication prescriptions, actual usage, and pain scores, providing decision-making support for pain management.

Strawberry is a commercially important crop which has gained global significance in terms of production and consumption. The strawberry farmers have been faced with economic losses due to attack from arthropod and phytophagus pests. To overcome this challenge, management of pests is important with reduced impact on beneficial organisms and the environment. Use of non-chemical approaches as an alternative to insecticide driven management is highly gaining popularity. Identification of the non-chemical production for management of strawberry pest such as entomopathogenic fungi and botanicals is critical. The need for compatibility of entomopathogenic fungi in crop production techniques with other insecticides to enhance efficacy is required. The interaction between these control agents could be synergistic, additive or even antagonistic. Synergistic interactions usually lead to enhanced effectiveness of the microbial control agents while reducing the adverse effects of the pesticides in combination. In this review a description of the compatibility of entomopathogenic fungus Beauvaria bassiana and botanical neem in strawberry pest management is given. The experiment involved five treatments: Neemraj, Beauvitech, Neemraj and Beauvitech, Ampligo and control. These treatments were allocated in a completely Randomized design in two separate greenhouse setups one with soil and other with pumice. The treatments were replicated four times. The data was subjected to analysis of variance (ANOVA) using the general linear model (GLM) procedure of the statistical analysis system (SAS) program, version 9.1. Tukey’s (HSD) test at P≤ 0.05 was used to separate significant means. The combination of Neemraj and Beauvitech was most effective in the management of pests in both hydroponics and soil grown media. Pest populations were reduced significantly as follows; thrips, Frankliniella spp 2.1, red spider mites Tetranychus species 11.5, tarnished plant bug Lygus species 3.0, there was 0% cricket Gryllus species damage and 0 number strawberry weevil in hydroponics cultures while in soil culture pest mean populations were: thrips 5.6, spider mites Tetranychus species 18.2, strawberry weevil (Otiorhynchus species) 7.0, tarnished plant bug 3.0 and there was 13.8% cricket Gryllus species damage on strawberry plants.

The frequency of candidiasis has surged worldwide, and the prevalent of healthcare diseases are now Candida species. Candida species causes a range of human infections known as Candidiasis. The non-albicans Candida (NAC) species have recently superseded Candida albicans as significant opportunistic pathogens. The study was conducted to determine the prevalence and antifungal susceptibility of Candida species isolated from various Clinical samples in Rivers State University Teaching Hospital, Port Harcourt, Nigeria. A total of 206 clinical specimens from male and female patients of all ages were sampled in the Department of Microbiology, Rivers State University Teaching Hospital, Port Harcourt, to investigate suspected Candida infections. The isolation and identification of Candida species was done by culture on SDA, Gram stain, sugar fermentation and phylogenetic profiling. Antifungal susceptibility pattern was done by Disc Diffusion method using Fluconazole, Ketoconazole, Miconazole, Nystatin and Itraconazole. The results showed that out of 206 specimens, 44 isolates (21.4%) were identified, with the majority (56.82%) from high vaginal swabs (HVS), followed by urine (31.82%) and oral swabs (11.36%). The age of patients ranged from four months to 73 years giving a Mean Age 1.86+ 0.344, with females (85.4%) outnumbering males (13.6%). Prevalence of Candida spp revealed Candida albicans (50%), Candida krusei (18.2%), Candida parapsilosis(11.4%), Candida glabrata and Candida tropicalis (9.1%) respectively and Candida pelliculosa (2.2%), with C. albicans being the most prevalent. The antifungal susceptibility testing among the azoles showed that Fluconazole (79.5%) and Ketoconazole (77.3%) were most sensitive agents against isolates from HVS, urine and oral swabs respectively and Itraconazole (34.1%) was most resistant especially to those from oral swabs. This study highlights the increasing prevalence of NAC species over Candida albicans and the growing resistance of Candida isolates to commonly used antifungal drugs. Diagnosis of these species of Candida and sensitivity to antifungal agents are critical components to treatment, particularly for patients with severe underlying illnesses who are hospitalized.

Wheat is a staple grain crop in the United States and around the world. Weed infestation, particularly grass weeds, poses significant challenges to wheat production, competing for resources and reducing grain yield and quality. Effective weed management practices, including early identification and targeted herbicide application are essential to avoid economic losses. Recent advancements in unmanned aerial vehicles (UAVs) and artificial intelligence (AI), offer promising solutions for early weed detection and management, improving efficiency and reducing negative environment impact. The integration of robotics and information technology has enabled the development of automated weed detection systems, reducing the reliance on manual scouting and intervention. Various sensors in conjunction with proximal and remote sensing techniques have the capability to capture detailed information about crop and weed characteristics. Additionally, multi-spectral and hyperspectral sensors have proven highly effective in weed vs crop detection, enabling early intervention and precise weed management. The data from various sensors consecutively processed with the help of machine learning and deep learning models (DL), notably Convolutional Neural Networks (CNNs) method have shown superior performance in handling large datasets, extracting intricate features, and achieving high accuracy in weed classification at various growth stages in numerous crops. However, the application of deep learning models in grass weed detection for wheat crops remains underexplored, presenting an opportunity for further research and innovation. In this review we underscore the potential of automated grass weed detection systems in enhancing weed management practices in wheat cropping systems. Future research should focus on refining existing techniques, comparing ML and DL models for accuracy and efficiency, and integrating UAV-based mapping with AI algorithms for proactive weed control strategies. By harnessing the power of AI and machine learning, automated weed detection holds the key to sustainable and efficient weed management in wheat cropping systems.

Helminth parasite infections in sheep are of major veterinary importance in many agro-ecological zones and are a primary factor in the productivity of sheep. The main objective of this study was to determine helminth parasites prevalence and their economic loss caused on sheep with its control approach at the study area. A cross-sectional study using a simple random sampling procedure was used to study helminth parasite identification at Gudaya Bila district during 2022 in two seasons of the year: winter (January - March) and summer (June - August). Out of 384 sheep chosen at random sampling from five Kebeles in the Gudaya Bila district (Welenelemu, Harogodisa, Chalejima, Hagelogidami, and Bila) that underwent flotation and sedimentation procedures, about 149 were infected by ay helminth parasites, with an overall prevalence 38.8%. Regarding the distribution of helimenth parasites at the class level, the prevalence was 13.9%, 11.7%, and 3.9% in trematoda, nematode, and cestoda, respectively. The helminth species that had highest prevalence were Fasciola species (19.5%), Haemonchus species (14.76%), Strongyloides species (10.74%), and Schistosoma species (9.4%), and those that had the least prevalence were Moniezia species (6.04%), Paramphistomum species (5.4%), Taenia species (4.02%), Nematodirus species (3.3%) and Trichostrongylus species (1.34 %). The summer season was favorable for helminths parasite transmission. The prevalence of helminths in the summer season was 98 (25.5%), and in the winter season it was 51 (13.3%). The study shows that the gastrointestinal helminth parasite was a major health problem and had an impact on the production of sheep in the study area. Therefore, a detailed study should be conducted to identify the parasite at the species level, and further investigation will be needed to study the association of the prevalence of helminth parasites within age, sex and the agroecology of sheep in the area. Then educating the people about the impacts of helminths is needed to control them.

Background Gender based violence (GBV) refers to any violence targeted at an individual or group on the basis of their gender. It could occur in different forms with several clinical manifestations. The authors have described several clinical manifestations of GBV in a tertiary health centre, knowledge of which would help in case identification and early clinical management. Methods Retrospective descriptive study of all clients seen at a gbv clinic over a sixteen months period.Data was obtained from case records and clinical presentations were entered into excel. Data analysis was done usingIBM SPSS Statistics for Windows, version 25. The results were presented in frequency tables and graphs Results Of 86 clients studied, 56(65.1%) were of pediatric age (< 18years) while 30(34.9%) were adults with a mean age of 18.33+11.64(range 1-64years).72(82.6%) belonged to the low social class. Physical abuse in the forms of battering, human bite, walking and sitting disturbances, hearing loss possibly from slapping or hitting and red eye possibly from trauma on the eye, constituted 37.6% of the clinical presentations. Other presentations were; sexual abuse in the form of forced sex which constituted 34.9%, while gynaecological / obstetrics presentations in the forms of bleeding per vagina, pregnancy due to forced sex and vaginal pain made up 13.9%. Emotional/psychological abuse was observed in all clients irrespective of their different presenting complaints. Conclusion While various forms of physical abuse were common, emotional abuse was present in all clients but masked probably due to prioritization of physical injuries. Therefore we recommend that all GBV survivors be screened for psycholocal abuse and psychotherapy given.

Using samples of small cell lung tumors, a research team led by biologist Dr. Raymond discovered two new ways to induce tumor cell death. By activating ferroptosis, one of two subtypes of tumor cells can be targeted: first, iron-dependent cell death due to oxidative stress, and second, oxidative stress. Therefore, cell death can also be induced in a different way. Both types of cell death must be caused by drugs at the same time to eliminate the majority of the tumor mass. It is currently in clinical trials for cancer treatment. Auranofin, which inhibits the production of protective antioxidants in cancer cells, has been used to treat rheumatoid arthritis for decades. Future clinical trials using this combination therapy will determine the extent to which this targeted treatment option improves the prognosis of small cell lung cancer patients. It is currently in clinical trials for cancer treatment. Lung cancer is the leading cause of cancer death in the United States. Despite evidence of molecular abnormalities in biological specimens, progress in this disease is hampered by the lack of diagnostic markers useful for clinical practice. The majority of patients with lung cancer are still diagnosed at an advanced stage, when prognosis is poor. This article reviews new strategies being studied for the early detection of lung cancer. These strategies involve new methods of imaging (including low-dose computed tomography CT scanning), DNA analysis, and proteomic-based techniques. These strategies have not only improved our understanding of lung cancer but show promise in offering better survival to patients with this deadly disease. Of paramount importance in the search for methods of early detection is the need for the identification of the ideal population to screen, a multidisciplinary approach, and validation of promising techniques.

Context In the face of further waves of the COVID-19 pandemic it becomes essential to find a balance between protective actions to guard public health and restrictive measures which can collapse our economy. Background As a basis for public health decisions, officials still rely on metrics which were helpful in the beginning of the pandemic but are now not precise enough for a focused and targeted approach to keep the spread of the infection under control. This can lead to public mistrust, “pandemic tiredness”, and can cause unnecessary damage to the economy without having the desired protective effect on public health. Methods This article discusses various metrics, their advantages and caveats, and it provides suggestions for use in a more targeted and risk-based approach, as an alternative to the current “general lock-down” practice. It suggests the notion of including a concept of “risk contacts per area” to better describe the possibility of virus transmission than currently published metrics do. The article also suggests specific analyses of real-world data for identification of populations at risk for severe courses of COVID-19 to allow more targeted protective actions. Discussion Data currently used to describe the COVID-19 pandemic lack important parameters like population density and local likelihood of potentially infectious contacts. The currently often used “all or nothing” approach of shut-down orders needs to be replaced by more sophisticated tactics considering individual local exposure risks and need to be balanced towards metrics on economic short term and long-term impact. In addition, smart analyses of real-world data may contribute to effective protection of individuals at risk.

This study investigated the potential pathogenic bacteria that are associated with domestic dog stool in Port Harcourt Metropolis. Convenience sampling techniques were used for sample collection outcome. A total of fifty dog stool samples were collected aseptically into a sterile stool container from different locations (Agip Estate, Rumuokoro Community, Government Residential Area, Sand-fill Borokiri, Port Harcourt Township, and Rivers State University lecturers’ quarters) all within Port Harcourt City. Bacteriological analysis was determined using standard microbiological analytical and identification techniques. Statistical analysis was performed using Statistical Package for Social Science version 21 for frequency, percentage, prevalence rate and correlation at 0.01 and 0.05 level of significance. Potential pathogens with associated percentages that were isolated are E coli (20.0%), Klebsiella species (16.0%), Pseudomonas species (4.0%), Proteus species (28.0%), Bacillus species (4.0%), Staphylococcus aureus (14.0%), and unidentified [other Staphylococcus species] (4.0%). However, the research further revealed that Proteus species (28.0%), was the most prevalent pathogen, while Bacillus species (4.0%), Pseudomonas species (4.0%), and Streptococcus species (4.0%), were the least prevalent among pet dogs studied. The correlation analysis showed no significant relationship between isolates with socio-demographic data of pet owner and Pet biodata respectively. From the analysis, correlation coefficient values of .269 and .124 were obtained for Age of Pet Owner and Gender of Owner respectively. It also show a direct correlation but by implication, a very weak, non-significant (p<0.05) relationship existed between the organisms isolated and the variables (Age of Pet Owner and Gender of Pet Owner). However, no relationship exists between isolates and visit to vet Doctor (r-0.038; p>0.05). Furthermore, negative non-significant correlation (p>0.05) was observed for marital status of Pet Owner (r=-.158) and Age of Pet (r=-.023) and isolate. Also, correlation association between isolates and some risk factors using the correlation analysis matrix revealed an indication of an indirect but moderate association between isolates and Caressing (r=-.347, p=0.01). However, other risk factors like vaccination (r=.042), Feeding Pattern(r=.125), Pet Bathing (r=.220) and Eating with pet in same plate (r=.146), did not prove statistical significance at p>0.05. The results from the study strongly suggest that pet dogs carry potential pathogenic organisms in their faecal matter that can serve as a source of infection to the pet owners. It is, therefore, very critical that these pets should be treated and possibly vaccinated frequently, even as their faecal matters should be well disposed to prevent possible zoonotic infectious epidemic outbreak in our global communities.

The following document provides important information that everybody know about physical exercise as a means of managing COVID-19. It addresses the health benefits of physical exercise on our body’s immune system, and stress reduction. Already today in the entire world, coronavirus is now the leading causes of morbidity and mortality. It kills thousands of peoples per day worldwide and continues its impact on the governments and the society. Nowadays it is the greatest public health problem in most countries in the world. Since its identification on Jan, 7 by the chines scientists named the pathogen as a novel coronavirus. In the current situation COVID-19 is rapidly spreading worldwide and the number of cases and deaths are rising up speedily. The spread of the virus is a headache to the government in general and the society in particular. The nature of the virus disallowed contacting with one another, working together, meeting, and other activities the majority of government and private business organizations are enforced to discontinue their work. The growing burden of the virus would place millions of jobs at risk an additional 8.8 million people in working poverty around the world. The danger of the disease and loss of employment leads the majority at stress. A chronically stressed person impairs the organism’s ability to mount a strong immune response with a resultant increase in morbidity and mortality.

By increase the incidence of infection of coronavirus disease 2019 (COVID-19), diagnostic factors for early identification of high-risk individuals are important. On the other hand, more infections are in older patient, comorbidities, and male patients. Identification of components that related to severity of COVID-19 contributed to ACE2 and TMPRSS2 genes, which are critical for viral infection. It was found that adding enzyme copy, hrsACE2, lures the virus to attach itself to it instead of the actual cells… It inhibits the virus from infecting the cells in the lungs and other organs.

Mucoepidermoid carcinoma (MEC) accounts for only 5% of all salivary gland tumors and is most often seen in the parotid glands. MEC occurrence in the larynx is, however, rare. The incidence of primary squamous cell carcinoma (SCC) of salivary glands is also scarce and comprises only about 1.6% of all salivary gland malignancies. Hereby, we share our experience in managing two patients with rare and opposite variants of malignancy which were diagnosed at the same time; MEC of the larynx and SCC of the parotid. In MEC tumors, the presence of the intermediate and mucous cells with positivity in mucicarmine stain are the significant features. For SCC tumors, identification of the usual tumor markers (p40, CK 5/6 and p63) are pathognomonic. Although MEC and SCC are common in the head and neck regions, the existence of these malignancies in exceptional locations must be considered. The key features mentioned in our comparison table can help distinguish both these tumors and to deliver the correct treatment modalities. The prevalence of genomic and carcinogenic factors in the occurrence of these tumors in uncommon locations needs to be explored in future studies.

This article has been retracted on 29 January 2021. VIEW THE RETRACTION NOTICE (https://doi.org/10.14302/issn.2372-6601.jhor-25-5854) In Côte d'Ivoire, sickle cell disease affects 14% of the population. It is responsible for significant morbidity and mortality. Transfusion is a significant element in the management of major sickle cell anemia, which exposes them to post-transfusion hemochromatosis. The biological diagnosis is based on the determination of serum iron and the transferrin saturation coefficient (CST). As the determination of the CST was not available in our exercise context in Côte d'Ivoire, we determined only the ferritinemia. The interest of this work lies in the therapeutic implication linked to the identification of patients at risk of hemochromatosis because chelators are difficult to access for most patients. This was a prospective, descriptive and analytical study, on polytransfused sickle cell patients, followed at the transfusion therapy unit (UTT) of the CNTS of Abidjan, from 2010 to 2018. We included 78 sickle cell patients, all ages and genders who have received at least ten transfusions. The ferritinemia assay was carried out by ELISA. Transfusion exchange, with 59% of cases, was the most used mode of transfusion. The mean ferritinemia was 1719.19 ng / ml. Hyperferritinemia was found in 63% of patients. Most of the patients were on a long-term transfusion program with an average of 27.5 bags of red blood cell concentrates. Thirty-two patients had received at least 20 bags of red blood cell concentrates. We noted 21 patients treated, including 3 with deferoxamine and 18 treated with oral deferasirox. We have identified 33 sickle cell anemia patients at risk for hemochromatosis. The determinants of the risk of hemochromatosis were the high number of blood bags and the method of transfusion.

Coronavirus nanoparticles show a strong peak of Plasmon absorption in ultraviolet–visible zone. A strong interaction exists between the surface of Coronavirus nanoparticles and Bcr–Abl tyrosine–kinase inhibitors (TKI) such as Imatinib (STI571), Nilotinib (AMN107), Dasatinib (BMS–345825), Bosutinib (SKI–606), Ponatinib (AP–24534) and Bafetinib (INNO–406). Bcr–Abl tyrosine–kinase inhibitors (TKI) such as Imatinib (STI571), Nilotinib (AMN107), Dasatinib (BMS–345825), Bosutinib (SKI–606), Ponatinib (AP–24534) and Bafetinib (INNO–406) cause to aggregation of Coronavirus nanoparticles linked to DNA/RNA and hence, lead to widening of peak Plasmon of Coronavirus nanoparticles surface at 550 (nm) and emerging a new peak at higher wavelength. In the current project, this optical characteristic of Coronavirus nanoparticles is used to time investigate of interaction between different Bcr–Abl tyrosine–kinase inhibitors (TKI) such as Imatinib (STI571), Nilotinib (AMN107), Dasatinib (BMS–345825), Bosutinib (SKI–606), Ponatinib (AP–24534) and Bafetinib (INNO–406) and Coronavirus nanoparticles. The results were shown that Bcr–Abl tyrosine–kinase inhibitors (TKI) such as Imatinib (STI571), Nilotinib (AMN107), Dasatinib (BMS–345825), Bosutinib (SKI–606), Ponatinib (AP–24534) and Bafetinib (INNO–406) with shorter chain length interact faster with Coronavirus nanoparticles. Therefore, a simple and fast method for identification of Bcr–Abl tyrosine–kinase inhibitors (TKI) such as Imatinib (STI571), Nilotinib (AMN107), Dasatinib (BMS–345825), Bosutinib (SKI–606), Ponatinib (AP–24534) and Bafetinib (INNO–406) with various chain length using red shift in surficial Plasmon absorption is presented.

Aim of the Research The aim of this study is to analyze a group of dogs of different breeds affected by osteosarcoma (OSA), to document any prevalence of this primary bone neoplasia in breeds that are phylogenetically close and to help with further research human medicine, as a model of study for prevalence and epidemiology of human OSA in multiple populations. Study Design Pilot study from two canine surgery databases between 2002 and 2013. Materials and Methods Breeds were classified in groups based on their phylogenetical proximity. Differences in prevalence of OSA between breeds and groups were evaluated with a permutation test. For each breed and each group, a ranking was made by calculating 95 % confidence intervals and counting the no-overlapping between breeds and groups. The relation between the dogs’ heights and the prevalence of OSA was analyzed using a logistic regression between the disease status and dog size. Results A total of 67 dogs with OSA, in 26 different breeds were included. Ten breeds were overrepresented and, the majority of these, were classified in 2 predisposed groups phylogenetically close to each other. The prevalence of OSA was associated with the dogs’ height within predisposed breeds, but, in general, taller breeds were not the most affected. Conclusions and Clinical Relevance In this study, despite the small number of dogs, we observed that the most commonly affected breeds with OSA are phylogenetically closely related. This highlights the importance of genetics in the aetiology of canine OSA . In this preliminary study, indications are given on breeds, samples and genome locations to be further investigated. This could allow identification of pathogenic alleles in dogs, and potentially in humans. Furthermore this pilot research can represent a model of epidemiologic study of human OSA.

Domestic pigeons (Columba liviadomestica) of the order Columbiformes are ubiquitous birds and can be found in virtually every town and city around the globe. Their interaction with humans and domestic animals and wild birds makes them a potential carrier of zoonotic parasites. The present study aimed to detect the prevalence of different zoonotic protozoans that affect different-aged domestic pigeons in different localities in Assiut Governorate, Egypt. A total of 50 fecal samples from 20 young and 30 adult pigeons were collected and examined for identification and estimation of prevalence of Cryptosporidium sp. and Microsporidium sp. using modified Kinyoun acid-fast stain. For detection of the prevalence of Toxoplasma gondii, serum samples from 50 pigeons were examined serologically for the presence of Toxoplasma antibodies by using Latex Agglutination test. The prevalence of Cryptosporidium sp. infection was 20%; 6.7% in adult pigeons and 40 % in young pigeons while that of Microsporidium sp. was 40% both in adult and young pigeons. Mixed infection was detected in only two young pigeons (10%). Regarding Toxoplasma gondii detection, the number of seropositive cases detected by LAT was 29 out of 50 (58%). The positive agglutination titers, among 14 (48.27%) seropositive pigeons ranged between 1:2 -1:128. It was concluded that domestic pigeons may be considered as a reservoir host for Cryptosporidium, Microsporidium, and Toxoplasmagondii human infection which represents a serious human public health problem especially for high risk groups of population living in the same dwellings with pigeons. Moreover, the present pilot results provide a baseline data for planning future researches and control strategies against domestic pigeon's parasites.

Background The morbidity and mortality associated with the multi drug resistant Gram negative bacterial infections pose a significant and growing challenge to clinical practitioners. Klebsiella pneumoniae, which is a substantial nosocomial pathogen and confer high levels of resistance to broad-spectrum antibiotics including carbapenems. The aim of this study is to determine the resistance profiles of Klebsiella pneumoniae strains isolated from various clinical specimens. Material and Method In this study, the antibiotic susceptibility profiles of 2452 Klebsiella pneumoniae strains isolated from various clinical specimens between July 2015 and November 2019 were considered retrospectively. Blood culture vials were incubated in Bac T / Alert 3D automated system, other samples were cultured on blood and Eosin Methylene-blue (EMB) medium. The identification and antibiotic susceptibility tests of the isolated bacteria were performed by VITEC 2 Compact ID-AST cards (BioMérieux, Marcy l’Etoile, Fransa) and the results were evaluated according to the standards of the Europian Committee on Antimicrobial Susceptibility testing (EUCAST). The first sample of each patient was included in the study. The strains with inappropriate results were re-studied with gradient agar diffusion test (BioMérieux, Marcy l’Etoile, Fransa). Results The study included a total of 2452 Klebsiella pneumoniae strains and the distribution of samples was as follows: 894 (36, 5 %) blood, 790 (32, 2%) bronchial lavage, 211 (8,6 %) wound, 148 (6 %) drainage, 148 (6 %) peritoneal fluid, 95 (3, 9 %) tracheal aspirates, 64 (2,6%) catheter, 62 (2,5 %) urine, 40 (1,6%) other samples (pleural fluid, cerebrospinal fluid, throat ). In this study, antibiotic susceptibility test results indicated that the resistance to tigecycline was lowest (0, 3%). High colistin resistance ratio (33, 5 %) in carbapenem-resistant Klebsiella pneumoniae was considered to be of concern. Conclusion In this study, high rates of resistance to carbapenems were noteworthy. Determination of hospital antimicrobial resistance rates will be useful in developing antibiotic use policies of each hospital, in the treatment of causative agents, in selecting antibiotics according to antimicrobial susceptibility.

Prostate specific antigen (PSA) does not provide the high reliability and precision that is required for an accurate screening for prostate cancer (PCa). The aim of our study was to search for a simple, rapid, direct, preferably non-invasive, and highly accurate biomarker and procedure for the screening for PCa. For this purpose the levels of bromine (Br) and zinc (Zn) were prospectively evaluated in expressed prostatic fluid (EPF). Also Zn/Br concentration ratio was calculated for EPF samples, obtained from 38 apparently healthy males and from 33, 51, and 24 patients with chronic prostatitis (CP), benign prostatic hyperplasia (BPH) and PCa, respectively. Measurements were performed using an application of energy dispersive X-ray fluorescent (EDXRF) microanalysis developed by us. It was found that in the EPF of cancerous prostates the levels of Zn and Zn/Br were significantly lower in comparison with those in the EPF of normal, inflamed, and hyperplastic prostates. It was shown that “Sensitivity”, “Specificity” and “Accuracy” of PCa identification using the Zn and Zn/Br levels in the EPF samples were all significantly higher than those resulting from of PSA tests in blood serum. It was concluded that the Zn and Zn/Br levels in EPF, obtained by EDXRF, is a fast, reliable, and non-invasive diagnostic tool that can be successfully used by local, non-urologist physicians at the point-of-care to provide a highly effective PCa screening and as an additional confirmatory test before a prostate gland biopsy.

Background The objective of this review is to unify the various genetic defects along with elaborating metabolic pathways in Familial Combined Hyperlipidemia(FCHL) and also to differentiate the phenotype of FCHL from metabolic syndrome. Methods PubMed and Cochrane’s library was searched for keyword “Familial combined hyperlipidemia” and latter with “Familial combined hyperlipidemia genes” to finally shortlist 23 articles. Further search with key words “molecular pathogenesis of familial combined hyperlipidemia” and “metabolic syndrome and familial combined hyperlipidemia” was carried out for finding molecular defects in FCHL, non-molecular findings distinguishing FCHL from metabolic syndrome and overlapping features between FCHL and metabolic syndrome. Results Major culprit regions identified included Chromosome-1q21-q24(USF1 and FOXA2) , Ch-11q (APOA5), Ch-16q24, Ch-20q12-q13.1, Ch.4q32.3 (rs6829588), and Ch-19q13.32 containing PVRL-2 gene (Also known as Nectin-2). The genetic and metabolic pathways linked to FCHL may involve: 1-Defective clearance of Apo-B containing lipoproteins, 2-Overproduction of Apo-B containing lipoprotein i.e., VLDL and 3-Adipose tissue dysfunction. FCHL phenotype showed close resemblance with metabolic syndrome clinical and biochemical features with slight differences. Conclusion The reviewed data suggested that FCHL phenotype is the resultant end outcome from multiple molecular defects and thus underlying genetic defect identification in the index case is important for personalized medicine and incoming gene therapy. Further research is warranted to explore specific genetic defects.

Head and Neck cancer (HNC) is one of the most prevalent and lethal cancer globally. The incidence of tobacco-induced HNC is gradually increasing in low and middle income countries. Among the various causative factors associated with HNCs, tobacco and alcohol play synergistic effect and are frequently associated with the risk of HNC. Tobacco-induced HNCs show distinct genetic and epigenetic alterations leading to different clinical outcomes in comparison to HPV-infected HNCs. Tobacco-induced HNCs are often associated with tumor aggressiveness, poor prognosis and low or nil prevalence of HPV infection. Apart from carcinogenic effects of these causative factors (use of tobacco products, alcohol intake and HPV or EBV infections), recent studies show that exposure to these factors alter/disrupt the regulation of non-coding RNAs including the long non-coding RNAs (lncRNAs). Altered lncRNA regulation is brought about by signalling networks that regulate cellular differentiation, apoptosis, angiogenesis and inflammatory pathways which play key functions in the genesis of different cancers including HNCs. There are numbers of studies supporting the emerging role of lncRNAs in development of HNC; however, reports connecting lncRNAs expression and addiction habits in HNC are still preliminary and sparse. Therefore, identification and characterization of lncRNAs that are differentially expressed upon exposure to risk-factors can serve as unique therapeutic targets and potential biomarker(s) for effective treatment of HNC subtypes. In this short review, we briefly reviewed the emerging role of lncRNAs in tobacco and alcohol induced HNCs.

Objective Antisocial behavior (ASB) in children and youth is public health problem in Georgia. Nevertheless, there has been no systematic study the risk factors for ASB that could counteract on ASB development. To prevent ASB development and acceleration the understanding of biological (assessment of Brain morphology using MRI) and psychological (assessment using Freiburg Personality Inventory) risk factors is critical. This was the aim of this study. Method The children/youth with ASB tendency (AST) were identified by the Freiburg Personality Inventory (FBI). The biological and psychosocial factors contributing to AST were evaluated using a semi-structured clinical interview. Brain anatomy and morphology was studied using magnetic resonance imaging (MRI). Results Children/youth with AST had significant abnormalities in most axial elements of the DSM multi-axial system but not in brain anatomy measured by MRI. Conclusion Early identification of ASB tendencies and a provide correlationship between specific psychiatric, medical and family stress factors will likely reduce the number of children/youth with ASB and will promote their integration into society.

Objective To investigate the major constituents of Tinosporacordifolia Willd. growing on Mangiferaindica, and to evaluate the efficacy of their antibacterial and cytotoxicity activities. Methods The ethanolic stem extract of T. cordifolia was subjected to silica gel 60 column chromatography, thin layer chromatography and medium pressure liquid chromatography for isolation of the major compounds. Identification of purified compounds was achieved by spectroscopic methods.. The crude extract and purified compounds were screened for their antibacterial and cytotoxicity properties using standard procedures. Results Two alkaloids were purified and identified as Magnoflorin (1) and Tembetarine (2). These compounds showed high antibacterial activity against Bacillus cereus and Staphylococcus aureus with both MIC (32-64 µg/ml) and MBC (128-256 µg/ml). The cytotoxicity activity of the purified compounds and crude extract was determined using MTT colorimetric assay against L929 and HEK293 cell lines. This showed weak cytotoxicity activity with IC50 values of 1162.24 to 2290.00 µg/ml and 1376.67 to 2585.06 µg/ml towards L929 and HEK293 cell lines, respectively. Conclusion The major compounds present in ethanolic stem extract of T. cordifolia growing on M. indica were extracted, purified and identified. This study suggests that these compounds exhibit great potential for antibacterial activity with weak cytotoxicity activity. They may be useful for their medicinal functions.

Background and Objective Identification of sex, age, race and stature is the most important aspect of any forensic investigation. There is a strong correlation of stature with hand dimensions and if either of the measurements is known, the other can be calculated. With this objective, the present study was designed to correlate the hand dimensions with stature of an individual and to record the standard deviation in the estimation of stature. Methodology This cross-sectional study was conducted amongst 1000 participants (500 male and 500 female) of ESIC Institute Gulbarga over a period of 14 months. Hand dimensions along with stature and weight were measured. Linear regression coefficient was calculated. Results Mean stature was 161.88 cm. Mean hand length was 18.11 cm on right side and 18.10 cm on left side. Mean hand breadth was 9.91 cm on right side and 9.83 cm on left side. Conclusion Highly significant difference in right and left side mean hand length and breadth measurements was observed. Also observed was a strong positive statistically significant correlation between height and hand dimensions. This data might be useful for forensic, epidemiological and anthropometric studies where stature determination is of utmost importance.

Head and neck cancers (HNCs) are the most prevalent and aggressive type of cancers. Genetic, epigenetic, environmental and viral risk-factors are associated with HNC carcinogenesis. Persistent infection of oncogenic human papillomaviruses (HR-HPVs) represent distinct biological, molecular and epigenetic entities in HNCs. There are three main epigenetic mechanisms that regulate transcription, these are DNA methylation, histone modifications and alteration in non-coding RNA networks, which can dissected to identify innovative and accurate epigenetic biomarkers for diagnosis and prognosis of HNC patients. Due to the lacunae of accurate distinctive biomarkers for the definite diagnosis of HNC, the identification of predictive epigenetic markers is necessary that might modify or increase HNC patient’s survival. In this mini review, we briefly summarize the current knowledge of different epigenetic biomarkers in HNC.

Epilepsy comprises a series of chronic neurological disorders characterized by recurrent seizures. Over 50 million people are affected by epilepsy worldwide. In addition, genetic components capable of predicting epilepsy predisposition and antiepileptic drugs response would lead to the development of promising treatment and a better prognosis of the disease. Several genes and their variants have been investigated whether they could affect the onset of epilepsy. The brain-derived neurotrophic factor gene, the ATP-binding cassette subfamily B member and the cytochrome P450 are the most common polymorphic genes related to epilepsy. Early identification of risk factors for epilepsy should optimize treatment and prognosis. The characterization of genetic polymorphism contribute to the selection of the most promising antiepileptic therapy and avoidance of drug resistance. The development of biomarkers to estimate the risk of epilepsy and drug resistance would have a clinical impact on the treatment of the disease and on anti-epileptic drug therapy.

Background: Co-morbidities are associated with increasing risk of mortality, hospitalizations and costs of treatment in Chronic Obstructive Pulmonary Disease patients. Identification of Co- morbidities related to COPD phenotypes may guide individualized therapies and achieve better prognosis. Methods: A prospective study of one hundred ten patients of confirmed COPD diagnosis were carried out and divided into five different phenotypes with related co-morbidities. History taking, clinical examination, Chest X-ray, Computed chest Tomography, laboratory investigations, arterial blood gas, Echocardiography and Electrocardiography were done for all patients. St. George’s Respiratory Questionnaire, COPD assessment test (CAT score) and BODEx (BMI, FEV1, dyspnea and exacerbations) were used for assessment of disease impact on quality of life, severity, and exacerbation respectively. Results: Emphysema group were 31% among all cases with mean age 61.8±9.1, frequent exacerbator group and Chronic bronchitis phenotype were 18% with mean age 64.4±11.3, and 48.8±9 respectively. COPD with bronchiectasis group were 19% with mean age 60.3±6 and Asthma COPD Overlap Syndrome (ACOS) were 12% with mean age 62.8±15.8. There was significant difference as regards age between different group of phenotypes P- value <0.001. There was significance difference in BODEx index and in (CAT) score among different COPD phenotypes P-value 0.020, 0.001 respectively. There was significant difference in all items of SGRQ among different COPD phenotypes P–value 0.001. Diabetes was commonly presented in 50 % ACOS cases, Ischemic heart disease was present more in Emphysema 22.9%, Osteoporosis was more in COPD with bronchiectasis 28.6%, Cor-pulmonale was more present in frequent excerbator 65%, and Anemia more common in COPD with bronchiectasis 23.8%. Depression was more common in frequent excerbator phenotype (45.0 %). Gastro-esophageal reflux was the most common co-morbidities (58 %) then cor-pulmonale 41.8%, systemic hypertension 40 % and pulmonary hypertension 28%. Conclusion: The presence of significant co-morbidities is important modifying risk factors for severity in COPD. They contribute to the overall severity in individual patients, have a major impact on quality of life, and major causes of hospitalization. Co-morbidities can be associated with any clinical phenotype.

Study Objectives: Narcolepsy diagnosis has been associated with a long lag time between the onset of the disorder and the diagnosis itself among patients with the disorder. This article reviews the childhood epidemiology of idiopathic narcolepsy, including its prevalence, subtypes, and disease progression. Methods: A literature review was conducted to include both published and unpublished data on pediatric narcolepsy. All English language articles were included through April, 2015. Results: Time from symptom onset to diagnosis for children is approximately three years. The prevalence of cataplexy appears to be lower in children compared to adults, suggesting a later onset of cataplexy. The presence of cataplexy, however, was unrelated to demographic factors and laboratory findings. Conclusion: There is a substantial lag-time between initial symptom presentation and diagnosis in children with narcolepsy. A less quintessential presentation of narcolepsy might occur in children relative to adults, making diagnosis more challenging. Continued improvements in narcolepsy education for both pediatricians and parents might facilitate earlier identification and diagnosis of the disease, thus leading to improved outcome.

Circular RNAs (circRNAs) are covalently closed single-stranded loop RNA molecules with or without protein coding capability. CircRNAs were previously considered to be splicing intermediates or artifacts but are now found to be pervasively expressed in all eukaryotes studied with some demonstrated to have important molecular functions in various biological processes. CircRNA is now a hot study topic of molecular biology. In this review, we summarize the progress achieved so far on plant circRNAs, including identification and functional characterization, compare the similarities and differences of circRNAs between plants and animals, and discuss the challenges for confident detection and functional investigation of plant circRNAs. Similar to what have been found in animals, plant genomes contain a large number of circRNAs that potentially regulate a wide range of biological progresses related to plant development and biotic/abiotic responses. Despite only a few plant circRNAs have been functionally characterized, novel function/mechanism that has not been reported in animals was revealed, implying more exciting findings about plant circRNAs are expected in future studies.

The possibility of tailoring treatment on specific characteristics of patients – i.e. personalized medicine – has received attention in the field of rheumatic diseases since biological DMARDs targeting a unique pathway have become available. However the idea of personalized rheumatology has advanced slowly, at different paces in different disease groups, and it is only now surfacing in the recommendations for assessment and treatment of rheumatoid arthritis (RA). Many of the difficulties encountered stem from the recognition that many rheumatic diseases are not a single entity but encompass different subsets identified on the basis of genetic traits, cellular and molecular characterization both in blood and in tissues, laboratory markers and clinical manifestations (most notably in SLE). These differences suggest a multiplicity of pathogenetic triggers, whose various combination results in slightly or very diverse presentations. Developments in companion diagnostics and the identification of distinct subsets within complex syndromes are going to allow the definition of predictive biomarkers able to reduce poor treatment outcome, thus ensuring that we are treating “the right patient with the right drug”.

Introduction The practices of having extreme and permanent body modifications as in tattoos and scarifications are gaining popularity among youths especially those in the universities. Not minding the unbearable and painful pressure of sharp objects on the tissues and the risk of being infected with blood transmitted infections including HIV, youths still engage in these practices. This study aimed to examine the extent to which university students are aware of the risks of using improperly sterilized and disinfected sharp objects. Materials and Method First year students in three universities, Federal, State and Private Universities were used for the study. A random sample of ninety (90) students made up of 30 students from each of the three universities studied was used. Drama was used as an intervention that will create awareness on risks of utilizing sharp objects in making scarifications. The completed copies of self-administered pre- and post-drama questionnaire were collected and analyzed quantitatively using Tables and percentages. Results Results showed that a good number of students 29 (97%) in Michael Okpara University of Agriculture (MOUA) , 28(93%) in Abia State University (ABSU) and 27( 90%) in Rhema University viewed sharing sharp objects like razor blades and syringes as risk to blood transmitted infections especially HIV. A total of 28(31%) of students both males and females in MOUA, ABSU, and Rhema had marks (scarification and/ or tattoos) on the body. The main reason for having the marks was for traditional identification and this was more among students in MOUA than in others. Conclusion Based on the results of the study, drama proved to be a valuable and timely intervention strategy that created awareness among university students on the risks of using sharp objects to make marks on the body.

Up till now, chitosan has confirmed its versatile application in skin, cartilage and bone tissue engineering, as well as in drug delivery applications. This study is focused on enzymatic degradation of porous chitosan structures usually designed for mentioned purposes. In vitro degradation was monitored during four weeks of incubation at physiological temperature and in two different media, phosphate buffer saline solution and water. The scaffolds were characterised before and after enzymatic degradation using scanning electron microscopy and infrared spectroscopy with Fourier transformations (FTIR). According to the gravimetric analysis, higher weight loss of chitosan scaffolds was observed in buffered medium with respect to the water. The results implied that the total weight loss obtained in buffer involves physical dissolution of chitosan and lysozyme cleavage of glycoside bond. Importantly, FTIR identification of chitosan scaffolds after enzymatic degradation indicated the absence of lysozyme activity in water, indicating that weight loss is a result of the chitosan dissolution. This finding greatly impacts design of degradation experiments and characterisation of degradation behaviour of chitosan-based materials utilised as implants or drug delivery systems.

Background: The nature of placenta previa can be unpredictable and harsh on the mother and baby. These complications are often unpredictable, unpreventable and often leave the labour ward team in a dilemma. This Obstetricians' nightmare is fortunately a rare complication. The frequency of placenta previa at the time of delivery average 1/200 births i.e. 0.5%. Placenta previa is still an important cause of maternal and fetal death in our country. The risk factors are Advanced Maternal age, Multi parity, Previous Cesarean Section, Multiple gestation, Previous Abortions, Previous intrauterine surgery, placenta previa in previous pregnancy, Smoking. Objective: Identification of risk factors, the feto-maternal outcome and complications of patients having placenta previa with previous caesarean section. Methodology: This cross sectional study was conducted from July 2012 to June 2015 in Obstetrics and Gynaecology department, Dhaka Medical College hospital. 100 patients of placenta previa were included in this study. Non-probability purposive sampling method was used for selection of patients. Results: In this study, Socio-demographic profiles, Identification of risk factors, the feto-maternal outcome and complications of patients having placenta previa were assessed. The frequency of placenta previa associated with previous cesarean section was 61%. In demographic profiles of the patients in this study - with a history of previous caesarean section, 78.7% patients were in the age group 26-35. Multiparity was predominant on scarred uterus group (63.9%). Here, demonstrated that > 2 previous history of caesarean section was associated with 80.3% of placenta previa. Regarding maternal outcome, complications like massive haemorrhage, ureteral injury, bladder injury, wound infection, DIC, maternal and perinatal mortality were more in the scarred patients than in the unscarred patients. In our study, 29.5% of morbid adhesion of placenta observed in scarred uterus. Conclusions: There is significant association of placenta previa with previous cesarean delivery. So, Careful monitoring of high risk pregnancies is of utmost importance. Avoidance of unnecessary caesarean sections and early week’s pregnancy terminations can minimize the Obstetricians' nightmare.

Some strains of Foot and mouth disease virus (FMDV) are endemic in Egypt. The present study was performed on cattle and buffaloes (ages: 3 months up to 1.5 years old, of years 2015 and 2016), which were suffering foot and mouth disease (FMD). Sera and tissues samples were tested by different techniques including serum and virus neutralization tests (SNT, VNT), virus isolation and identification by tissue culture methods, Enzyme linked immune-Sorbent Assays (ELISA); and by the pathological and hematology techniques. The results showed the predominance of FMDV serotype O with the presence of serotypes SAT2 and A. The results showed the pathologic picture of FMD was similar regardless its specific subtypes, as apparently the studied strains produces same pathological and hematological changes. Microscopic examination reveals severe hydropic degenerations and necrosis in most affected organs, accompanied by significant changes in blood parameters which indicate severity and direct effects of FMDV on the hematopoietic system. These findings indicates the mode of pathogenesis of FMD virus in its way to exhibits the characteristic symptoms of illness. However, the investigation showed the presence of FMDV type O, A and SAT2 in the studied areas of delta governorates. It is important to focus on producing of vaccines which have only these serotypes as solution to get rid of the endemic behavior of FMDV in delta of Egypt.

Perkinsus marinus is an intracellular parasitic protozoan that is responsible for serious disease epizootics in marine bivalve mollusks worldwide. Despite all available information on P. marinus genomics, more baseline data is required at the proteomic level. Our aim was to study the proteome profile of in vitro cultured P. marinus isolated from oysters Crassostrea spp. using a label-free shotgun UDMSE approach. A total of 4073 non-redundant proteins were identified across three biological replicates with stringent identification. Proteins specifically related to adaptive survival, cell recognition, antioxidants, regulation of apoptosis and others were detected. Important virulence factors of P. marinus were identified including serine protease and iron-dependent superoxide dismutase. Other proteins with involvement in several pathogens invasion strategies were rhoptries, serine-threonine kinases, and protein phosphatases. Interestingly, peptides corresponding to retroviruses polyproteins were identified in all replicates. The interactomic analysis of P. marinus proteins demonstrated extensive clusters network related to biological processes. In conclusion, we provide the first comprehensive proteomic profile of P. marinus that can be useful for further investigations on Perkinsus biology and virulence mechanisms.

Fingerprint is an impression made by the friction ridges that are almost parallel at constant crest to crest wavelength. The pattern is dominated by central features, such as whorls, loops, arches and triradii. Fingerprints have been used for several decades in forensic and medical sciences. The fingerprints characteristics such uniqueness, consistency and universality are the main features that are used by forensic experts in identification processes, are well developed during intra-uterine life. Understanding embryogenesis of fingerprints is essential in linking its features to some disease conditions. The purpose of this review was to highlight information regarding establishment, formation, hypotheses and factors affecting fingerprints. Applications of the fingerprints in forensic and medical sciences were also highlighted. Both environmental (in utero) and genetic factors have role to play in the formation of the fingerprints. The primary role of fingerprints is personal identification; these can be achieved through revealing sex, ethnicity, diet and lifestyle of an individual. In another perspective the fingerprints can be used as tools in diagnosis and ascertaining presence of disease conditions, however, this is population specific.

An important step in the validation of disorder-specific etiological models is the examination of the predictive specificity of proposed vulnerability factors. It may advance the understanding of the emergence of comorbidity and the identification of at risk-populations for mental disorders. To enhance the currently limited evidence on the specificity of Beck´s cognitive diathesis-stress model of depression, the present study investigated longitudinal effects of dysfunctional attitudes and stressful life events on the development of depressive, eating disorder and aggressive symptoms in children and adolescents. A large sample of initially asymptomatic children and adolescents completed self-report symptom measures at study entrance and again approx. 20 months later, and reported stressful life events during the study interval. Stressful life events proved to be a risk factor to all investigated symptom domains. Dysfunctional attitudes at T1 were prospectively related to depressive symptoms, aggressive behavior and weight concerns at T2. However, types of associations varied as dysfunctional attitudes showed linear associations with weight concern, but nonlinear effects on depressive and aggressive symptomatology. Findings of the current study thus suggest that dysfunctional attitudes are not uniquely related to the development of depressive symptomatology in children and adolescents, but may contribute to adverse outcomes in various symptom domains. Thus, intervention efforts based on Beck´s vulnerability - stress model of depression may turn out to be useful in reducing vulnerability to a variety of outcomes in children and adolescents.

Our objective was the early identification, assessment and treatment of aggression by primary school children four to eleven years old, with the goal of preventing school expulsion. The children were identified by teachers and other professionals for their aggressive behavior. Children were assessed for five symptoms which are linked to the development and persistence of social and/or physical aggressive behaviors: inattention, hyperactivity, anxiety, poor social functioning, and oppositional behavior. Long term follow-up continued for up to 9 years. Conners’ Scales for parents and teachers were used to assess the severity of predisposing symptoms and emotional lability. The children were treated with psychosocial and pharmacological interventions by social workers and a physician, in addition to utilizing community and school resources. Teachers reported a reduction in some of the predisposing symptoms: hyperactivity, emotional lability, oppositionality, and improved social functioning. Parents reported improvements in all five of the children’s physically aggressive behaviors. Early intervention for children’s aggressive behaviors was found to be effective. None of the children in the study were expelled from school.

The mitotic count is the most frequent reason for discordance between pathologists in modified Bloom and Richardson (mBR) scoring. Recently, the phosphohistone H3 (PHH3) immunohistochemical stain has been proposed as a potential surrogate marker for mitotic figures. This study examines the differences between H&E mitotic count, PHH3 mitotic count, and Ki-67 index in invasive breast carcinoma. A retrospective review of invasive breast carcinoma cases from 2013- 2014 was performed. H&E and PHH3 mitotic counts were assigned a mitotic score of 1 to 3 using mBR criteria. Ki-67 index was categorized into a three-grade system: <10% (low), 10 - <20% (intermediate), and >20% (high). A total of 451 cases were evaluated. PHH3 versus H&E mitotic count changed mBR scores in 24% of cases, upgrading in 23% and downgrading in 1%. A total of 431 cases had both Ki-67 and PHH3 available for comparison. Both H&E and PHH3 mitotic scores correlated with Ki-67 in 51% of cases; however, PHH3 had better correlation. We conclude that PHH3 in breast carcinoma allows for a more sensitive and practical approach in the identification of mitotic figures. PHH3 IHC is useful as a confirmatory tool in assessing the final mitotic score for more accurate mBR scoring and grading. In this study, 48 out of 451 (10.6%) of patients had a significant upgrade that may change the patient's treatment plans, including the addition of chemotherapy

Background: Depression is related to suicidal ideation, attempts, and completion. However, depression fails to provide any specific identification for suicide risk. Hopelessness has been found to provide a more accurate estimate of suicide risk than seen in depression severity, and hopelessness can serve as a useful predictor of eventual death by suicide. Aims: The present study was designed to examine various levels of hopelessness and their association with other symptoms experienced by depressed psychiatric inpatients. Method: 150 adult psychiatric inpatients were evaluated using a structured diagnostic interview and several standardized self-report questionnaires. All patients met criteria for a depressive diagnosis at the time of the evaluation. Patients were classified into four discrete categories of hopelessness using the Beck Hopelessness Scale. Results: No differences were observed when the four groups of depressed psychiatric inpatients were compared on demographic variables and background clinical events. However, several key differences were observed between groups on measures of depression severity, suicidal ideation, and tendencies to cope by distraction. Conclusions: It appears useful to evaluate suicide risk as it changes across different levels of hopelessness. Depressed patients with higher levels of hopelessness report more severe problems on several dimensions related to suicide risk.

Diabetes mellitus type 2 (DMT2) is a complex polygenic disorder. DMT2 is a result of insulin resistance and destruction of pancreatic β-cell or dysfunction. Therefore, glucose builds up in the bloodstream, leading to nerve damage, blindness, organ failures and sometimes death. Recently, some recently discovered genes play a key role in regulating the sensitivity to insulin. Scientists have long known that the disease often runs in families, and other genetic links. Human genetic discoveries will keep improving our knowledge about diabetes for many years to come. Varieties of prospective diabetic researches were developed to diagnose and control DMT2. Researchers spent thousands of millions of dollars to address DMT2. Pioneers of advanced biotechnology developed bioinformatics tools that changed the course of research about the role of metabolomics in DMT2. It will facilitate the identification of possible causes of DMT2 in genome studies. The present article aimed at reviewing the research studies per training to metabolomics and bioinformatics in genome studies in relation to DMT2.

The number of individuals with diabetes is increasing worldwide and a large subset of those affected will develop diabetic nephropathy. Diabetic nephropathy is the leading cause of end-stage renal disease, has serious health consequences for affected individuals, and represents a major monetary cost to healthcare providers. Technological and analytical developments have enabled large-scale, collaborative studies that are revealing risk factors associated with diabetic nephropathy. However, much of the inherited predisposition and biological mechanisms underpinning risk of this disease remain to be identified. Meta-analyses and integrated pathway studies are becoming an increasingly important part of research for diabetic nephropathy including, genetic, epigenetic, transcriptomic, proteomic research, clinical observations and the development of animal models. This report highlights current bioinformatic resources and standards of reporting to maximise interdisciplinary research for diabetic nephropathy. The identification of an -Omics profile that can lead to earlier diagnosis and / or offer improved clinical evaluation of individuals with diabetes would not only provide significant health benefits to affected individuals, but may also have major utility for the efficient use of healthcare resources.

Defining protein-protein interactions is essential for understanding the mechanisms by which cells regulate basic functions, such as metabolism, transcription, and signal transduction. Affinity purification followed by tandem mass spectrometry (AP-MS) has application for discovery of new interactors regulating various cellular processes. Here we optimize the purification method for AP-MS and develop a simplified unbiased analytical tool, Z-score plus prey occurrence and reproducibility (ZSPORE) for data analysis. Using this pipeline we achieve a higher efficiency of AP-MS and enhanced identification of high confidence interacting proteins (HCIP) in mammalian cells. When applied to analysis of the innate immune interactome, these methods enhanced HCIP identification. In addition, we investigated the GRB2 complex, which is associated with signal transduction and cell growth. Twenty-four known GRB2 interacting proteins were identified plus 26 new GRB2 binding partners. Thus, these straightforward methods recapitulate known protein interactions, discover novel complexes, and allow mapping of protein interaction networks.
