Anoxic survival requires the matching of cardiac ATP supply (i.e. maximum glycolytic potential, MGP) and demand (i.e. cardiac power output, PO). We examined the idea that the previously observed in vivo downregulation of cardiac function during exposure to severe hypoxia in tilapia (Oreochromis hybrid) represents a physiological strategy to reduce routine PO to within the heart's MGP. The MGP o...

The immunomodulatory activity of Cod liver oil (CLO) was evaluated by mice lethality test, carbon clearance assay, neutrophil adhesion test, cyclophosphamide-induced neutropenia, indirect haemagglutination test and effect on serum immunoglobulin levels. CLO was administered orally at a dose of 0.5 g/kg or 1 g/kg body weight. In mice lethality test, low dose of CLO (0.5 g/kg, po) produced 40% de...

this experiment was conducted to evaluate the effects of different levels of portulaca oleracea (po),medicinal plant, on performance, egg traits, blood biochemical and immunity parameters of laying hens. one hundred eighty hi-line (w-36 strain) mature laying hens 65 up to 76 weeks of age were allotted in a completely randomized design consisting of 5 treatments and 3 replicates (12 birds per re...

Angiotensin II (Ang II) is implicated in the proinflammatory process in various disease situations. Thus, we sought to determine the role of Ang II in early inflammation-induced fibrosis of pressure-overloaded (PO) hearts. PO was induced by suprarenal aortic constriction (AC) at day 0 in male Wistar rats, and they were orally administered 0.1 mg/kg per day candesartan every day from day -7. Thi...

Propylene oxide (PO), a simple alkylating agent used in the chemical industry, is weakly genotoxic and induces nasal cavity tumors in rodents on inhalation at high air concentrations. DNA adducts, hemoglobin adducts, and sister chromatid exchanges (SCE) were analyzed as biomarkers of exposure in a group of eight PO-exposed workers and eight nonexposed subjects. 1-2-Hydroxypropyladenine (1-HP-ad...

The catalytic performances over propylene epoxidation with H2 and O2 (HOPO process) are significantly affected by the properties (e.g., surface properties, Ti coordination, morphology) of titanosilicate zeolite. Introducing urea into zeolite synthesis is a simple convenient method to modify these Uncalcined pore-blocked titanium silicalite-1 (TS-1, i.e., TS-1-B) lower dosage possesses more defe...

Maxwell’s equations are a set of first order partial differential equations describing the behavior of the electric and magnetic fields generated by distributions of charges and currents. Such equations also possess solutions for the case where there are no charges nor currents. The simplest solutions of this kind, discovered by Maxwell himself, describe electromagnetic field configurations whi...

The prophenoloxidase activating system (proPO-AS) in fresh water crab, Barytelphusa cunicularis is localized in the hemocytes. Using anticoagulant (EDTA-Citrate buffer) it was possible to isolate intact hemocytes without causing extensive degranulation & subsequent clotting. Activation and conversion of prophenoloxidase to phenoloxidase(PO) was carried out by serine proteinase. PO was found to ...
