Erythropoietin (Ep) regulates the proliferation and differentiation of erythroid progenitor cells, but whether it functions solely as a survival factor or also acts as a mitogen is unresolved. Because late erythroid progenitor cells (CFU-E) are largely in cell cycle, we examined this issue by using an Ep-dependent, murine erythroleukemia cell line, HCD-57.(More)
The antifungal effect of three furyl compounds closely related to resveratrol, (E)-3,4,5-trimethoxy-β-(2-furyl)-styrene (1), (E)-4-methoxy-β-(2-furyl)-styrene (2) and (E)-3,5-dimethoxy-β-(2-furyl)-styrene (3) against Botrytis cinerea was analyzed. The inhibitory effect, at 100 µg ml(-1) of compounds 1, 2, 3 and resveratrol on conidia germination, was(More)
In the present work, known concentration of sulfite aqueous solutions in the presence and absence of gallic acid was measured to corroborate the validity of modified Monier-Williams method. Free and bound-sulfite was estimated by differential pulse voltammetry. To our surprise, the modified Monier-Williams method (also known as aspiration method) showed to(More)
