Maintenance of an acid-base balance is essential for normal physiological processes in vertebrates. Freshwater fishes live aquatic environment with variable pH, and their buffering capacity body fluids weak. Thus, after acid exposure, secrete excess to prevent internal acidosis. Acid-secreting ionocytes present the adult gills embryonic skin are primarily responsible secretion, H + -ATPase Na /...

liver secretes a large range of very low density lipoprotein (vldl) particles of different sizes and svedberg flotation rates (sf). in plasma vldl is converted to low density lipoprotein (ldl)which in turn plays an important role in the development of atherosclerotic diseases; however,triglyceride (tg) rich vldl1 has been shown to be more deleterious than cholesteryl ester (ce) rich vldl2. ther...

introduction: gonadotropin inhibitory hormone (gnih) is believed to be an inhibitor of gonadotropin releasing hormone (gnrh) secretion. the role of gnih in lactational inhibition of gonadotropin secretion is not well known therefore, the aim of the present study was to evaluate the effect of lactation on expression of gnih in these nuclei of lactating and non-lactating rats. methods: ten postpa...

Objective(s): Biocompatibility of dental biomaterials plays a critical role in regeneration of dental stem cells. The aim of present study was to evaluate the effects of novel biomaterials of TheraCal-LC (TheraCal; Bisco), Angelus mineral trioxide aggregate (MTA; Angelus), calcium-enriched mixture (CEM; BioniqueDent), and Biodentine (Septodont) on viability of human de...

The effects of cAMP-analogue dibutyryl-cAMP and anticalmodulin W-7 were studied on de novo synthesis and secretion of lipids in cultures of hepatoma McArdle RH7777 cells and normal rat hepatocytes. Dibutyryl-cAMP and W -7 separately caused a significant decrease in the secretion of de novo synthesized triacyl [3H]glycerol in both cultures of McArdle cells and rat hepatocytes. The inhibito...

Background and Aims: Total hip arthroplasty (THA) is a common orthopedic surgery. The main focus in the research of THA is immune responses in these patients following the blood transfusion.Therefore, in this study, we evaluated the immune modulation indexes such as T cell amplification, Tcell surface markers and also production of cytokines in the patients undergoing THA surgery following bloo...

conclusions these human-derived lab and bifidobacteria exhibited different mechanisms involved in pathogenic inhibition. therefore a combination of these probiotic strains could be a great promise and possibility for the development of probiotic products to effectively prevent and control food-borne infection in humans. background food-borne pathogens are among the most significant problems in ...

Type 2 diabetes mellitus (T2DM) is a chronic, progressive disease characterized by steady decline in beta-cell function and insulin resistance. As result, most patients with T2DM may require treatment after 15–20 years of diagnosis. Various pathophysiological defects were identified leading to hyperglycemia, including reduced secretion due failure. They mass defect secretion, which leads relati...

Mesenchymal stem cells (MSCs) have been widely used in regenerative medicine and clinical therapy due to their capabilities of proliferation, differentiation, immune regulation. However, during vitro expansion, MSCs are prone aging, which largely limits application. Prostaglandin E-2 (PGE-2) is a key effector secreted by exert immunomodulatory effects. By screening the compound library for PGE-...
