using environmental-friendly methods in order to remove or reduce oil pollutants and their derivations in the environment are developing. in this study, the biodegrading ability of bacillus subtilis .sp which has been separated from oil-polluted soil was examined. it was revealed that it can reduce surface tension of growth medium and produce bio-surfactant at 37 and 20 degrees centigrade. also...

ABSTRACT. The consumable palm wine has never been used in heat treatment process of steels. This research therefore focuses on the utilization and other tree products as quenchants. mechanical physical properties samples were also evaluated to determine which quenchants that influences hardness corrosion rate values medium carbon steel most. test was performed 1.0 M HCl solution homemade vinega...

indirect evidence suggests that estrogen is involved in the etiology of breast cancer. estrogen is also thought to modulate nitric oxide (no) in human breast tumor tissue via regulation of inducible nitric oxide synthase (inos). objectives of this study were to determine whether estradiol (e2) affects inos expression level in breast cancer cells and to study the effect of various concentrations...

background: the main goal of the present study was to set up an axenic cultivation of acanthamoeba and assess the pathogenic ability of t4 genotypes from different clinical and environmental strains of acanthamoeba using two physical assays. methods: sixteen acanthamoeba isolates including 10 environmental and 6 clinical strains were cul-tured axenically. axenic cultivation was performed using ...

phosphate concentrations declined, indicating turnover of this compound. Incubation of LSI78Y cells in medium containing 0.5 ^M MMPR reduced intracellular concentrations of adenosine triphosphate, guanosine triphosphate, and adenosine diphosphate by about 70% and proliferation rates by about 30%. Upon transfer of such cells to M MPR-free medium, nucleotide levels and proliferation rates returne...
