Epidemiological studies have suggested that hormones, genetic factors, and environmental agents are significant risk factors in breast carcinogenesis. Some pesticides have the ability to act as xenoestrogens in vivo. The CYP19 gene encodes the aromatase enzyme which is involved in the estrogens biosynthetic pathways. We have assessed the frequency alleles of a (TTTA) n repeat of CYP19 gene...
Six water-soluble nystatin-polyvilnylpyrrolidone complexes with respective MW of 10 kDa (NC1), 25 kDa (NC2), 30 kDa (NC3), 40 kda (NC4), 90 kDa (NC5), 360 kDa (NC6) were synthesized. The activity of the complexes was compared with that of nystatin against growth and spore germination ofFusarium oxysporum f.sp. radicis-cucumerinum. The ED50 value (effective dose) of free nystatin in aqueous solution...
