ABSTRACTBackground: Radioprotective effects of famotidine, an antagonist of H2 receptor clinically used for peptic ulcer treatment, was previously shown on radiation-induced micronuclei and chromosomal aberration in human peripheral blood lymphocytes and mouse bone marrow cells. This study was conducted to investigate radioprotective property of famotidine against radiation induced apoptosis i...

body centric wireless communication (bcwc) has been the topic of much research in recent years. in this manuscript, a novel low-cost microstrip patch antenna is designed for on-/off-body communications with a dual-band operation. the proposed structure exhibits a monopole-like radiation pattern at 2.45ghz and a broadside radiation at 4.8ghz, simultaneously. lateral dimensions of 42 mm × 46 mm a...

The term radiation is elastic. Unfortunately it has come to mean “something terrible” in ordinary conversation. Literally radiation means “anything emitted from a localized source”, but in the context of biology we mean something quite specific. Human beings live amidst a sea of radiation of all sorts. It is useful to classify these radiations according to their biological effects, especially o...

ionizing radiation causes dna damage and chromosome abbreviations on normal cells. the radioprotective effect of celecoxib (clx) was investigated against genotoxicity induced by ionizing radiation in cultured human blood lymphocytes. peripheral blood samples were collected from human volunteers and were incubated at different concentrations at 1, 5, 10 and 50 μm of clx for two hours. at each do...

background: therapeutic radiopharmaceuticals are designed to deliver high doses of radiation to selected target organs with an aim of minimizing unwanted radiation to surrounding healthy tissue. due to the potential of targeted radiotherapy to treat a wide range of malignant conditions, [153sm]-samarium maltolate was developed for possible therapeutic applications. materials and methods: the or...
