Recently, the effects of antimicrobial activity of silver nanoparticles was considered by researcher because of Bacterial resistance to antimicrobial agents in chemical.The aim of this study was to evaluate the antimicrobial activity of the gold nanoparticles on Escherichia coli. Gold nanoparticles are chemically synthesized. Standard strain of E. coli was cultured in a nutrient broth. Minimum ...

Objective: Alpha-glucosidase, as a carbohydratase catalyses the liberation of alpha-glucose from the nonreducing end of some carbohydrates from foods in digestive tract. Consequently, retard absorption of glucose by the inhibition of carbohydrate hydrolyzing enzymes is one of the therapeutic approaches to decrease the postprandial hyperglycemia. Recently, a great deal of attention has been pai...
nitro-containing heteroaromatic derivatives structurally related to nitroimidazole (metronidazole) are being extensively evaluated against helicobacter pylori isolates. on the other hand, 1,3,4-thiadiazole derivatives have also demonstrated promising antibacterial potential. in present study, we evaluated anti-h. pylori activity of novel hybrid molecules bearing nitroaryl and 1,3,4-thiadiazole ...
Introduction: Physalis alkekengi (Solanaceae) is a rich source of various antioxidants. There are some reports that show P. alkekengi has been used for treatment of a wide range of diseases including gout and inflammation. Xanthine oxidase plays a crucial role in gout. Many natural compounds such as various flavonoids have been reported to have inhibitory effect on xanthine oxidase. Metho...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
Lipoxygenase(LOX) catalyzes irreversible transfer of oxygen molecule to Arachidonic and Linoleic acid to produce 13 Hydroproxy Octadecadienoic acid. Recent studies showed the involvement of Lipoxygenase products, leukotrienes, in inflammations and Lipoxygenase pathways acts as mediators of early inflammatory events in atherosclerosis. The aim of the present study was purification and characteri...
A lymphocyte blastogenesis inhibitory factor (LBIF) has been characterized as an immunoregulatory molecule, especially on the T-lymphocyte proliferation. Using fast protein liquid chromatography-purified LBIF, we examined the effect of LBIF on the proliferation of various 18 tumor cell lines in vitro in comparison with those of interferon-alpha, interferon-gamma, tumor necrosis factor-alpha, tr...
Background: Since cannabis has been legally allowed for medicinal purposes in many countries, it has become more interesting issue, particularly in neurologic disorders such as Alzheimer’s disease (AD). Inhibition of acetylcholinesterase (AChE) is one of the mechanisms for the treatment of AD. Objectives: The present study aimed to establish a method for preparation of cannabinoids-rich extrac...
