actinomycetes were isolated from marine sediment samples collected from the east coast of chennai, tamil nadu, india. well diffusion and agar plug methods were used for the evaluation of antibiotic production by these isolates against drug resistant methicillin- resistant staphylococcus aureus (mrsa) and vancomycin resistant enterococci (vre). the potential isolate vitbrk2 was mass cultured for...

background: reduced level of physical activity, as an important problem of urbanization and industrial development, has a considerable impact on the population morbidity and mortality. the rate of inactivity has been reported to be 60-85% in adults worldwide. considering the importance of physical activity among youth, the aim of this study was to evaluate the physical activity among university...

in the present study, the effect of apamin (potassium channel blocker) on tolerance to cocaine-induced locomotor activity in mice has been investigated. locomotor activity was measured by locomotor activity meter, animax, type s (lkb, farrad). intraperitoneal (ip) injection of different doses of cocaine (2.5, 5, 10 and 15 mg/kg) produced dose-dependent locomotor activity in mice.animals were tr...

the characteristics of manganese and iron binding to human apotransferrin (apo-tf) have been investigated and compared in this study. both metal ions were taken up by human apo-tf and formed complexes, with the maximum absorbances observed at 410 and 340 nm for manganese-transferrin (mn-tf) and 465 nm for iron-transferrin (fe-tf). addition of manganese (1.5 µg/ml) to the reaction mixture contai...

to introduce ecologically safe acaricide, effects of essential oils derived from cuminum cyminum (cumin), syzygium aromaticum (clove), and mentha spicata (spearmint) were determined on tetranychus urticae at 25±1◦c, 65±5% rh and a photoperiod of 16:8 (l:d) hour. the essential oils extracted by hydro-distillation were characterized by means of gc and gc–ms. bioassays were performed by filter pap...
