DdrA protein binds to and protects 3' DNA ends and is essential for preserving the genome integrity of Deinococcus radiodurans following treatment by gamma radiation in an environment lacking nutrients. Limited proteolysis was used to identify a stable and functional protein core, designated DdrA157, consisting of the first 157 residues of the protein. In vitro, the biochemical differences betw...

mutation induction is considered as an effective way to enrich plant genetic variation, particularly fortraits with a very low level of genetic variation. this research was conducted to assess genetic variationinduced by gamma radiation in m2 and m3 mutant lines of canola (brassica napus l.) by ssr and morphologicalcharacteristics and to identify useful mutants in terms of agronomic traits. six...

Alfalfa in dry stress conditions cannot grow optimally. Drought inhibits growth and reduces alfalfa production many cultivation systems. Plants breeding with gamma-ray irradiation vitro selection using PEG found somaclonal variants adapted to well drought conditions. This study aims determine the type of mutation best morphology mutants resulting from gamma were sub-cultured vitro. cultured med...

background: radiotherapy has many side effects on fertilization in young women. radiation can lead to ovarian failure in women who underwent abdomen or pelvic radiotherapy. objective: this study helps us to investigate ovarian response of nmri female mice to ovarian stimulating hormones (pmsg, hcg) after whole-body gamma irradiation. materials and methods: 45 pregnant mice were divided into two...

Background: Currently available radioprotectors are poorly tolerated in man and the general use of aminothiols is compromised by their side effects. This study was carried out to test and compare the radioprotective potential of cimetidine and famotidine against lethally gamma irradiated NMRI mice. Materials and Methods: Adult male NMRI mice in groups of 10 were exposed to various doses of gamm...

an extensive study was undertaken to investigate on the overall film badge service performance with which occupational radiation, exposures are reported in iran, the study involved the analysis of film badges exposed to x-and gamma rays and beta particles. for test exposures, x-rays between 60 and 140 kvpco-60 gamma radiation and sr-90 beta particles were used. the actual delivered dose equival...
