The Effect of X-rays on Glutathione
Hammctt (I), using the qualitative nitroprusside reaation, demonstrated the destruction of glutathione when water solutions were irradiated with p and y rays from radium. Woodward (2) confirmed Hammett’s observations quantitatively with radon, but failed to find any destruction with as high as 15,600 r units of Roentgen rays. She used the accurate titration method of Woodward and Fry (3) for ma...

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولEffect of Adenosine Agonists on the Proliferation and Differentiation of Chick Embryo Fibroblasts in Three Dimensional Reconstituted Tissue Constructs
Previous studies indicate that organ fibroblasts play an important role in wound healing, collagen production, remodeling processes and pathogenesis of progressive heart, lung, renal and hepatic fibrotic diseases. Several studies suggest a possible inhibitory role for adenosine in the regulation of fibroblast proliferation. The effect of adenosine A2 agonists on proliferation and differentiatio...
متن کاملThe combined effect of hydroxyurea and x-rays on Chinese hamster cells in vitro.
Hydroxyurea inhibits DNA synthesis in Chinese hamster cells and is selectively toxic for cells actually in DNA synthesis (i.e., in S phase) at the time of exposure to the drug. Synchronized cells in G1 inhibited from entering S by hydroxyurea show a complex response to X-radiation. Cells become steadily more sensitive for a period of about 4 hr and then recover about a normal G1 sensitivity in ...
متن کاملCombined exposure of ELF magnetic fields and x-rays increased mutant yields compared with x-rays alone in pTN89 plasmids.
We have examined mutations in the supF gene carried by pTN89 plasmids in Escherichia coli (E. coli) to examine the effects of extremely low frequency magnetic fields (ELFMFs) and/or X-rays to the plasmids. The plasmids were subjected to sham exposure or exposed to an ELFMF (5 mT), with or without X-ray irradiation (10 Gy). For the combined treatments, exposure to the ELFMF was immediately befor...
