background: there are many studies to investigate the effects of each interacting component of tumor-immune system interactions. in all these studies, the distinct effect of each component was investigated. as the interaction of tumor-immune system has feedback and is complex, the alternation of each component may affect other components indirectly. objective: because of the complexities of tum...

basil (ocimum basilicum l.) belongs to the lamiaceae family as a medicinal plant used in traditional medicine in iran. the purpose of this test is to evaluate the effect of nano fe-chelate under salinity levels on the plant physiology and morphology characteristics. in this experiment  investigated the effect of nano fe-chelate and salinity stress on growth parameters, photosynthetic leaves rat...

spinal cord injury (sci) is a trauma that disturbs motor, sensitive and autonomic function and directly impacts the quality of life. after physical damage, releasing of pro-inflammatory proteins and cytokines occurs and with collaboration of immune system cells, an immune response begins in the brain tissue. the result of neuroinflammation is edema, apoptosis and release of axonal growth inhibi...

addition of n-butyl nitrite to isolated rat hepatocytes caused an immediate glutathione depletion followed by an inhibition of mitochondrial respiration, inhi- bition of glycolysis and atp depletion. at cytotoxic butyl nitrite concentrations, lipid  peroxidation  occurred  before  the  plasma  membrane  was  disrupted. cytochrome p-450 inhibitors inhibited peroxynitrite formation and prevented ...

cr(iii), co(ii), ni(ii), cu(ii) and zn(ii) salts of 2-(4-nitrophenylaminocarbonyl)benzoic acid were characterized by physical, analytical and spectroscopic studies and checked for their  in-vitro antimicrobial activity against three bacterial strains, mycobacterium smegmatis (gram +ve), escherichia coli (gram -ve), pseudomonas aeuroginosa (gram -ve) and three fungal strains, nigrospora oryzae, ...

bachground: endometriosis is a disease of female genital system, which is defined by the presence of ectopic endometrial tissue outside the uterine cavity. il-8 is an autocrine growth factor in the endometrium that contributes to the pathogenesis of endometriosis. the aim of this study was to investigate the association between -251t/a polymorphism in the il-8 gene and endometriosis risk in ira...

the formation of charge-transfer complexation between dibenzo-15-crown-5 (db15c5) and benzo-12-crown-4 (b12c4) (donor) and iodine is investigated spectrophotometrically in three chlorinated solvents,chloroform, dichloromethane (dcm) and 1,2-dichloroethane (dce) solution at 25°c. the change in polarityof the solvent also doesn’t affect the stoichiometry of the complexes. values of formation cons...

the aim of this study was to optimize protease production using a novel bacillus sp. zr-5 strainisolated from the soil, and evaluate its application in detergent industry. the proteolytic activityof the strain was demonstrated using gelatin hydrolysis screening test. protease productionoptimization was carried out using a two-step approach: a conventional method in order toidentify the best car...

two series (a and b) of n- substituted heteroaromatic compounds related to clotrimazole were synthesized. imidazole ring of the clotrimazole was replaced by 2-methylimidazole in series a, and by 2-methyl-4-nitroimidazole in series b. o-cholortrityl moiety of clotrimazole was also replaced by trityl, mono or dimethoxy trityl. chemical structures of all the new compounds were confirmed by spec-tr...
