the present study was conducted to evaluate the effect of dietary inclusion of silver nanoparticle on general performance and digestive proteases in zebra fish. four experimental diets were designed with a concentration of 5, 20 and 40 parts per billion (ppb) nanoparticles in the diet (named s5, s20, and s40, respectively) and control group without any nanoparticles (s0). there was no significa...

in this research, cellulose-silk composites production in liquid phase was studied. in this respect,bmimcl ionic liquid was synthesized in the laboratory and was used for dissolution purpose. afterdissolution of the biopolymers and mixing them in the liquid phase, obtained suspension was spread ina petri dish. then, the composite gel was washed with running methanol to remove the il, cellulosea...

We have characterized proteolytic fragments of the chick intestinal 1,25-dihyroxyvitamin D3 (1,25(OH),D3) receptor, produced through either exogenous or endogenous protease action, utilizing a variety of physical and functional assays coupled to immunoblot detection methodology. Treatment of intestinal cytosol with increasing concentrations of trypsin resulted in a progressive diminishment of ...

slurries of rice-straw cellulose (obtained by delignification and removal of hemicelluloses from the powdered raw material) were subjected to ultrasonic waves at different intensities for various times (constant temperature). susceptibility of the samples to cellulose-hydrolysis increased initially with pretreatment time, reaching a maximum or a constant level thereafter. maximum glucose yield ...

the effect of bleaching with sodium hypochlorite, as one of the most important parameters in obtaining optimal alpha cellulose pulp from cotton linter was studied. in this respect, unbleached cotton linter pulp was prepared from parchin chemical industry co., bleached by hea sequence in ph=9, 11 and 13; and then its chemical structures properties such as alpha cellulose, degree of polymerizatio...

background bedsore is one of the major problems in all the societies as patients are confined to bed. due to antibiotic resistant strains being a significant obstacle for cure, many plants and herbs are being used by researchers as medicinal compounds. objectives the investigation of synergistic effect of cellulose biopolymer and papaver macrostomum extract on bedsores bacterial community. mate...

losartan potassium is a well known orally active non-peptide angiotensin ii receptor antagonist. losartan potassium and its principle active metabolites block the vasoconstrictor and aldosterone secreting effect of angiotensin ii by selectively blocking the binding of angiotensin ii to at1 receptors. the drug is reported to promote the decrease in ventricular hypertrophy, salt and water excreti...

probable use of chemical and biochemical detergents to wash polysulphone membranes using in milk ultrafiltration needs a multidisciplinary investigation. by increasing use of these membranes in food processing, washing and recovery of initial permeate flux, in order to use for a longer time from this technology, has much importance. in this research, influence of chemical detergents including e...

objective: the use of antiretroviral drugs has proven remarkably effective in controlling the progression of human immunodeficiency virus (hiv) disease, but these benefits can be compromised by the development of drug resistance. this study aims to assess the drug resistance profile of the pr gene in highly active antiretroviral therapy (haart)-treated and naïve hiv-1 infected patients. metho...
