background: ionizing radiation induces the production of reactive oxygen species (ros), which play an important causative role in cell death. the aim of this study was to investigate the protective effects of sulfated derivatives of neutral polysaccharides extracted from auricularia auricular (snaap). materials and methods: whole blood samples from healthy donors treated with snaap at different...

Introduction: Radiotherapy is still one of the main options for cancer treatment but it is in association with damage to normal cells as well as the tumor cells. To reduce the injury in normal cells we have evaluated the effect of 528 hertz sound after X irradiation in peripheral blood lymphocytes. Materials and Methods: in this study, peripheral blood was o...

in order to find a prophylactic supplementation for individuals who are at risk of exposure to ionizing radiation, we attempted to evaluate the effect of vitamin e (vit-e), a biological free radical scavenger, on restoration of hepatic lipid peroxidation (lpo) and lipid profile (lp) changes induced by sublethal g- radiation in balb/c mice. the concentrations of cholesterol and phospholipid were...

Abstract 200 years of Greek independence… and PMs.

background: radioprotective effect of famotidine was previously shown on radiation induced micronuclei and chromosomal aberrations in human peripheral lymphocytes and mouse bone marrow cells however, its radioprotective property has never been studied in mouse spermatogenesis. it was also shown that vitamin c as an antioxidant also exert its radioprotective effect on many biological systems, bu...

Telomere length and stability is a biomarker of aging, stress, and cancer. Shortening of telomeres and high level of DNA damages are known to be associated with aging. Telomere shortening normally occurs during cell division in most cells and when telomeres reach a critically short length, DNA damage signaling and cellular senescence can be triggered. The induction of an adaptive response by sp...
