ii abstract the legend of human being’s refulgence was distorted completely in the age of modernity. this new age, had some drastic negative effects, besides its positive qualities. one significant negative effect of it was the emergence of neurosis in human beings. aldous huxley’s brave new world was one of the novels of the 02 th century that contained the prophecy of criticizing ...
background: radioprotective capability of histamine h2 receptor antagonists have been shown in several in vivo studies mainly using animal models. however, to verify the effectiveness of these agents in clinical applications, studies should be performed on human cells. in the present study radioprotective properties of these agents was examined in vitro on human lymphocytes using metaphase anal...
Many of our students seem to have well-defined but not necessarily well-founded opinions on the biological effects of ionizing radiation. During discussions of nuclear transformations in introductory chemistry and physics courses we might be able to help these students better understand the magnitude of these effects, and perhaps sort out the plethora of units with which radiation measurements ...
background: the earlier atomic bomb explosion in hiroshima and nagasaki, and three worth mentioning nuclear accidents - detonation at fukushima daiichi nuclear plant, chernobyl nuclear fallout and an accident at three mile island nuclear power plant have made us more worried about the secure exploitation of nuclear energy. the central focus of this paper is to review radiation-mediated health e...
there has been a gradual shift of focus from the study of rule systems, which have increasingly been regarded as impoverished, … to the study of systems of principles, which appear to occupy a much more central position in determining the character and variety of possible human languages. there is a set of absolute universals, notions and principles existing in ug which do not vary from one ...
objective: in radiation treatment, the irradiation which is effective enough to control the tumors far exceeds normal-tissues tolerance. thus to avoid such unfavourable outcomes, some methods sensitizing the tumor cells to radiation are used. iododeoxyuridine (iudr) is a halogenated thymidine analogue that known to be effective as a radiosensitizer in human cancer therapy. improving the potenti...
