Several methods are currently available for selection when conducting sperm cryopreservation, however, these methods might cause different degrees of damage on sperm DNA. The aim of the this study is to compare the effects of storage at −80 °C (in ultra-low temperature refrigerator) and at −196 °C (in liquid nitrogen) on sperm DNA damage, thus to provide a reference for choosing the right method according...
The aim of the present study was to evaluate the genotoxic effects induced by native and active bentonite particles (BPs) on human B lymphoblast cells using comet assay and cytokinesis-block micronucleus (CBMN) assay in vitro. The cells were exposed to BPs at the concentrations of 30, 60, 120 and 240μg/ml for 24, 48 and 72h, respectively. The quartz contents of native and active BPs were 6.80±0.20...
DNA damage of peripheral lymphocytes in 60 workers occupationally exposed to trivalent chromium [Cr(III)] in a tannery was studied using comet assay. The urinary and blood chromium levels were detected as a biomarker of internal exposure. The 90 subjects were divided into three groups: (i) exposure group I included 30 tannery workers highly exposed to chromium from tanning department; (ii) exposure...
