Purification and Characterization of Gamma-Aminobutyric Acid (GABA) from E. faecium BS5 and Its Antidiabetic Efficacy in Streptozotocin-Induced Diabetic Rats.

A non-proteinaceous amino acid called GABA is well-known for its physiological uses and its role as an inhibitory neurotransmitter in the brain of mammals. Apart from its neurological function, GABA has been linked to blood pressure reduction and glucose balance modulation. Since β-cell destruction and decreased insulin secretion are hallmarks of diabetes mellitus, the natural production of GABA by pancreatic β-cells increases the possibility of its therapeutic role.

Global deletion of COX-2 attenuates hepatic inflammation but impairs metabolic homeostasis in diet-induced obesity.

The role of cyclooxygenase-2 (COX-2), a well-known pharmacological target for attenuating inflammation, in regulating obesity and its comorbidities remains unclear. We sought to determine the role of COX-2 in modulating metabolic inflammation and systemic metabolic homeostasis in obesity. Male WT and COX-2 KO mice were fed a chow diet or a high fat diet (HF, 45% fat) for 13 weeks.

Correlation between microRNA-21 expression and overweight/obesity.

Obesity and overweight are chronic conditions characterized by excessive adiposity that negatively impact health. They are among the most significant risk factors for respiratory failure, diabetes mellitus, cardiovascular disease, and hypertension. Genetic factors may contribute to some of these conditions, but they are mainly associated with the lifestyle in the majority.

Long-term Supplementation of Deep-fried Oil Consumption Impairs Oxidative Stress, Colon Histology and Increases Neurodegeneration.

Background: Sesame oil and sunflower oil are popular cooking oils in southern India. Deep-frying is a frequent method of food preparation. Deep-frying at high temperatures has been linked with several disorders, including cancer, diabetes, and unknown metabolic problems.

Investigating the Association Between Fusobacterium nucleatum and Oral Squamous Cell Carcinoma: A Pilot Case-Control Study on Tissue Samples.

Background ()has been increasingly linked to oral squamous cell carcinoma (OSCC), prompting this study to explore its presence using polymerase chain reaction (PCR) and evaluate its clinical significance. Methods In this pilot case-control study, 12 OSCC tissue samples and 12 non-cancerous oral mucosal tissue samples were analyzed. Total RNA extraction and complementary DNA (cDNA) synthesis were performed using Trizol-based methods, followed by PCR amplification and gel electrophoresis.

New insights into the antibacterial mode of action of quercetin against uropathogen Serratia marcescens in-vivo and in-vitro.

In the course of a quest for therapeutic agents inhibiting uropathogens, the rise and universal blowout of antibiotic-resistant organisms is a wide problem. To overcome this matter, exploration of alternative antimicrobials is necessary. The antimicrobial potential of quercetin has been widely described against some pathogenic microorganisms, but to the best of our knowledge, no report exists against the pathogenicity of uropathogenic Serratia marcescens.

Structured form of DHA prevents neurodegenerative disorders: A better insight into the pathophysiology and the mechanism of DHA transport to the brain.

Docosahexaenoic acid (DHA) is one of the most important fatty acids that plays a critical role in maintaining proper brain function and cognitive development. Deficiency of DHA leads to several neurodegenerative disorders and, therefore, dietary supplementations of these fatty acids are essential to maintain cognitive health. However, the complete picture of how DHA is incorporated into the brain is yet to be explored.

Anti-listerial activity of microalgal fatty acid methyl esters and their possible applications as chicken marinade.

Fatty acid methyl esters (FAMEs) from marine microalgae have been reported to possess antimicrobial activities against several Gram positive and Gram negative bacteria, but a majority of them needs to be explored. The objective of this study was to investigate the antibacterial activity, mechanism of FAMEs from selected marine microalgae against Listeria monocytogenes, and to elucidate its efficacy in food model. The minimum inhibitory concentration of FAMEs was calculated to be 155 μg/mL for Chromulina sp.

Listeria monocytogens - Amended understanding of its pathogenesis with a complete picture of its membrane vesicles, quorum sensing, biofilm and invasion.

Listeria monocytogenes is a ubiquitous, intracellular foodborne pathogen that causes listeriosis in animals and humans. Pathogenic Listeria monocytogenes easily adapted to the conditions of human gastrointestinal tract and tolerate the counter changes such as acidity, bile, osmolarity, and antimicrobial peptides. They secrete specialized biologically active extra organ called membrane vesicles which comprises proteins, lipids, and lipopolysaccharides.

Lowering the culture medium temperature improves the omega-3 fatty acid production in marine microalga sp. CASA CC 101.

Marine microalga sp. contains omega-3 fatty acids like eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Environmental factors play a major role in PUFA biosynthesis.

Omega-3-rich Isochrysis sp. biomass enhances brain docosahexaenoic acid levels and improves serum lipid profile and antioxidant status in Wistar rats.

Background: Isochrysis sp. is a marine microalga, rich in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The potential use of its biomass as an alternative source of polyunsaturated fatty acids (PUFAs) has not been studied in animal models.

Gut microbial degradation of organophosphate insecticides-induces glucose intolerance via gluconeogenesis.

Background: Organophosphates are the most frequently and largely applied insecticide in the world due to their biodegradable nature. Gut microbes were shown to degrade organophosphates and cause intestinal dysfunction. The diabetogenic nature of organophosphates was recently reported but the underlying molecular mechanism is unclear.
