introduction: α-amylase is a major form of amylase found in humans and other mammals. it is the special key enzyme involved in carbohydrates breakdown. inhibition of this enzyme could be used in treatment of diabetes. in this study, the effect of ten iranian macrolichens on alpha amylase were tested. methods: different concentrations of the extracts (25, 50 and 75 mg/ml) were incubated with enz...

this study aimed to investigate the anti-angiogenic activity of vitex agnus castus methanol extract in vivo. eggs were incubated for three days, small whole made on the fine pinpoint, next day the egg’s sac penetrated and a small frame was made in the shell. the window was resealed and eggs were returned to the incubator until day 10 of chick embryo development, 20 µl of 500mg/ml of the methano...

Shale inhibitor is an additive for drilling fluids that can be used to inhibit shale hydration expansion and dispersion, prevent wellbore collapse. Small molecular quaternary ammonium salt enter the interlayer of clay crystal, enables excellent inhibition performance. In this paper, a novel ionic inhibitor, triethylammonium acetate (TEYA), was obtained by solvent-free synthesis using acetic aci...

conclusions our findings indicate that umbelliprenin exhibits concentration-dependent inhibitory effects on various cell types; it is potentially toxic against the ht29, ct26, mcf-7, 4t1, a172, and gl26 cell lines, potentially harmful against bmdscs, and non-toxic against pbmcs. therefore, if our results are approved in the future, umbelliprenin can be an appropriate candidate for developing tr...
