Leptin in Energy homeostasis, Male reproduction, and Immune regulation
Discovery of leptin has changed the view of adipose tissue from energy storehouse to active neuroendocrine and immune organ. Adipokineleptin is a16 kDa amino acid protein, encoded by LEP gene, secreted by adipose tissue, and acts through leptin receptor which is a cytokine receptor. Leptin is a central regulator of energy homeostasis by regulating food…

Lactobacillus casei and Bifidobacterium bifidum reduces postprandial hyperglycaemia, inhibits α-glucosidase activity and improve histology of pancreatic islets in streptozotocin induced diabetic rats
Lactobacillus and Bifidobacteria are generally accredited as potential anti-diabetic agents, but the mechanism of action is still not clear. This study aimed to investigate the result of administration of Lactobacillus casei and Bifidobacterium bifidum on α-glucosidase enzyme, postprandial blood glucose level, and histological changes that occur in the pancreatic β-cells in streptozotocin (STZ (50 mg/kg body weight)) induced diabetic rats.…

Orexins: the ‘multitasking’ neuropeptides in the energy metabolism and immune regulation of male reproduction
Orexins are hypothalamus-derived neuropeptides with versatile functions. The most explored domains of orexins’ functions are their influence on the central nervous system (CNS) implicated in the regulation of sleep/wakefulness cycle, food intake behavior, energy homeostasis, and cognitive processes. Orexins reportedly bear two isoforms, orexin-A (OXA) and orexin-B (OXB), that act via their specific G protein-coupled…

Chemerin and male reproduction: ‘a tangled rope’ connecting metabolism and inflammation
Adipokines are peptides produced mainly by the fat tissue adipocytes and their levels are sensitive to alterations in metabolic state. While there is little known about the impact of adipokines on male reproductive control, both animal-based experimental data and clinical research suggest that they can influence numerous male fertility indices. Chemerin is a newly found…

An economic and efficient synthesis of acid-labile glycerol based β-thiopropionate esters for potential application in drug delivery
Acid labile linkers have been used widely for various biomedical applications with preferential applications in drug delivery. In this report, we have synthesized, glycerol based b-thiopropionate esters having an acid-labile β-thiopropionate linker with Michael addition reaction between hydrophobic thiol and hydrophilic tri-glycerol diacrylate. The solvent free reaction and purification by simply solvent extraction instead of…

Phytochemical and in vitro analysis of Bornetella oligospora extract as alpha-Glucosidase inhibitor
One of the first-line therapy of diabetes mellitus is alpha-glucosidase inhibitors. Due to side effects caused by synthetic drugs and limited sources, various studies have been conducted on herbal plants and macroalgae consisting of bioactive compounds with alpha-glucosidase inhibitory activity. This study examines the alpha-glucosidase inhibitory activity and phytochemical compounds in ethyl acetate and ethanol…

Beneficial impacts of Astaxanthin on Biomarkers of Antioxidant status and oxidative damage in Rats exposed to Ambient air
Effect of astaxanthin from Haematococcus pluvialis on lipid peroxidation and oxidative stress induced by ambient air exposure was studied. Wistar albino rats were exposed to ambient air was administered with astaxanthin in doses varying between 0.5 to 2% of food intake. Various biological parameters like ALT, AST, ALP, malondialdehyde, hydrogen peroxide, superoxide dismutase, catalase and…
