What is meant by genetic effects of radiation two-stage genome-wide association study was carried out in head and neck cancer HNC patients aiming to identify genetic variants associated with either specific radiotherapy-induced RT toxicity endpoints or a general proneness to develop toxicity after RT. This may own to the sample size of patients in bby discovery study, which was a limitation to the study as it rendered the identification of low-penetrance genetic variants less likely. The effects of ionizing radiation are often measured in units of gray for mechanical or sievert for damage to tissue. Some of genetiv genetic differences, however, because they affect the enzymes of the metabolic pathway of vitamin D, have proven to be important in the determination of vitamin D deficiency.

Abstract Abstract. Although considerable variation of radiosensitivity was found among rice varieties, Japanese genstic was comparatively more susceptible to pile radiations than foreign varieties, and tetraploids were less susceptible as compared with the diploid varieties after irradiation.

From die observation of the radiation injury of F 1hybrids it was concluded that, in addition to the contribution of a gene or a gene system, the cytoplasm was related to the intervarietal difference of radiosensitivity. Sterility was more easily induced by pile radiations than X-irradiation. In the Fenetic series, chlorophyll mutations on the X 1 -ear basis reached a maximum frequency at middle doses and decreased at higher doses. In the pile radiation series the frequency increased with increasing doses.

The cause of differences of these two series seemed to be a difference of the mean size of mutated sectors between both the radiations. The increment of induced variation on quantitative characters occurred in plus radiationn minus direction with similar frequencies after the treatment of pile radiations.

However, the heritable variations did not increase in accordance with neutron flux. The amount of induced variation was more in the progenies of partially sterile X 1 ear and less in those which segregated whqt mutants in X 2 generation. It was calculated that 1 r of X- and gamma-rays was equivalent to x 10 9 thermal neutrons per cm 2 for induction of chlorophyll mutations and of variation on quantitative characters.

Associations between genotypes i endpoints were tested using a logistic regression model for binary endpoints and a linear regression model for STAT continuous scores. Lohman et al. Ensembl Overall, the literature reveals that the consequences of hypovitaminosis D on bone health are observed in old and infrequently in young subjects. It can be concluded that the deficiency of vitamin D is a definite health problem in Argentina. In the pile radiation series the frequency increased with increasing doses.
