REDOX ENZYMES: From Basics to Free Radical Scavenging

Abstract:

Redox enzymes are a type of enzyme that catalyzes redox reactions, that is, electron transfer reactions between two chemical species. Redox enzymes are essential for many biological processes, including cellular respiration, photosynthesis, energy production, and the elimination of free radicals.

They are divided into two main types: oxidoreductases and electron transferases. Oxidoreductases catalyze the direct transfer of electrons between two chemical species, while electron transferases catalyze electron transfer by cofactors.

Examples of redox enzymes include cytochrome c oxidase, NADH dehydrogenase, succinate dehydrogenase, and catalase. Each of these enzymes play an important role in cellular metabolism and organism homeostasis.

ANH in Complex Cardiac Surgery: A Prospective Randomized Study

Abstract:

Blood transfusions in cardiac surgery are associated with increased morbidity and mortality. The purpose of this study is to identify potential benefits of ANH in high-risk cardiac surgery.

Synthesis of N-Glycosyl Amides via Hydrolysis of Protected Glycosyl Oxazolines and Ritter-like Reactions of Native Carbohydrates

Abstract:

A stereoselective synthesis of N-glycosyl amides was studied from available N-glycosyl oxazolines prepared by Ritter-like reactions of protected sugar acetonides. Hydrolysis reactions of the protected pentofuranosyl and hexafuranosyl oxazolines, as precursors of glycosyl amine derivatives, were carried out in the presence of silica gel in chloroform to giveN-α- and β-glycosyl amides in good yields after column chromatography on silica gel. Access to selectively blocked N-α-xylo-, -ribo-, β-arabino-furanosyl, α-glyco-, α-allo-furanosyl, α- and β-galactopyranosyl amides (twelve examples) useful for preparing modified N-glycosides was accomplished through a mild hydrolysis of sugar oxazolines with 2-alkyl substituents in acidic and neutral conditions. To further explore the sc...

Perceptions and Suggestions Towards Adolescent Sexuality Education Among Secondary School Teachers in Region 1, The Gambia

Abstract:

Comprehensive Sexuality Education (CSE) is a school-based intervention aimed at correcting misinformation surrounding sexual education among youth, often influenced by social media, peer groups and misleading online content. In The Gambia, the Ministry of Basic and Secondary Education has developed and introduced a national framework to integrate CSE from Grade 4 (primary school level) to Grade 12 (senior secondary school level).

This study explores the perceptions and recommendations of 50 secondary school teachers from 43 public and private schools in Region 1 on the implementation of CSE in schools. While some teachers expressed concerns that CSE might promote perverted and lewd early sexual behavior, others saw it as essential for increased awareness and youth well-being. Cultural, religious, and societal norms pose significant implementation barriers towards the implementation of CSE in schools. Teachers’ insights are vital for...

Extended Bioethics as a Response to Global Biological Consciousness

Abstract:

Humanity is persistently threatened by global pandemics- exemplified by the Black plague, the Spanish flu, and COVID-19, which reveal a continual absence of concern in real-time prevention. To forecast biological threats in the future and spur proactive human response, the term Global Biological Consciousness (GBC) is introduced.GBC requires an Extended Bioethics, a dynamic ethical framework for conscious management mediated by GBC. This perspective will enable preventive actions and will seek global biological resilience through the algorithmic responsibility of AI and systemic justice, as will be explained in the work. The GBC, through Extended Bioethics, will provide an ability to analyze biological data as it occurs using AI and quantum computing, expect outbreaks before they happen and attenuate their effects, here creates a new ethical contract for all humankind as they co-exist in a biological world.

Impact of Agricultural Land Use Practices on Water Quality in Lubigi Wetland

Abstract:

Wetland encroachment due to agricultural land use practices (LUPs) adversely affects water quality in wetlands mainly through agricultural runoff. This study was conducted in Lubigi wetland in Uganda to (1) determine the effect of the agricultural LUPs on water quality and (2) understand the relationships between different water quality indicators and different agricultural LUPs existing in the wetland. The eight LUPs included in this study were perennial crops i.e. banana farming and sugarcane farming, annual crops i.e. maize farming and tomato farming, livestock farming which included a mixture of cows, goats, and sheep, undisturbed dense natural vegetation, reference wetland and the river. Water samples collected from the different LUPs were analyzed in the laboratory for selected physicochemical and biological water quality parameters. The water samples were analyzed for a variety of properties, including pH, electrical conductivit...

Keratinophilic Fungi: Diversity And Abundance in the Soil of Ajmer District, Rajasthan

Abstract:

Soil is a natural habitat and ecosystem for microorganisms, including bacteria and fungi. Mostly keratinophilic fungi are found in soil, use keratin as a growth substrate, and are essential to the natural degradation of keratin waste. These fungi include dermatophytes, a potential source of infectious diseases in humans and animals and cause dermatophytosis. One hundred thirty-six soil samples were collected from several sites including animal habitats in Ajmer district, Rajasthan, India. The soil samples were used for the study of keratinophilic fungi related to species richness, abundance, and diversity. The Physio-chemical properties of collected soil samples were analyzed and examined in soil microflora for temperature, pH, and macronutrients including nitrogen, phosphorus, and potassium. Ninety-eight soil samples (72%) showed positive results for the keratinophilic fungal isolates. The isolated fungal species belonging to eight...

Impact of Phytase-Supplemented Palm Kernel Cake on Growth, Feed Efficiency, and Economic Viability in Poultry

Abstract:

The rising costs of conventional poultry feed ingredients, such as soybean, maize, and fish meal, have prompted the search for more affordable and sustainable alternatives in poultry production. This study investigates the use of phytase-supplemented Palm Kernel Cake (PKC) as a replacement for soybean meal to improve feed efficiency, nutrient absorption, and growth performance in poultry. White Leghorn layers, Rhode Island Red layers, broilers, and cockerels were fed three different feed formulations: conventional feed (CF), Moderate PKC with Phytase (MPP), and High PKC with Phytase (HPP). The results showed that PKC-based diets significantly reduced feed costs while maintaining satisfactory growth, although CF led to higher body weight gain and feed efficiency. The MPP formulation struck an optimal balance between cost savings and nutritional quality, making it a viable option for layers and cockerels, while C...

A Comparative Study of Temporalis Fascia Graft and Cartilage - Perichondrium Graft in Tympanoplasty

Abstract:

The repair of the tympanic membrane has been attempted with large variety of synthetic, homologous and autologous tissue; however, temporalis fascia and cartilage-perichondrium are used most commonly today.
