Dental bleaching is a simple and conservative procedure for aesthetic restoration of vital and non-vital discolored teeth. Nevertheless, a number of studies have demonstrated the risk of tissue damage...
A Preliminary Study of DNA Damage in Peripheral Lymphocytes from Lung Cancer Patients and Healthy Subjects
Comet assay DNA damage Lung cancer Lymphocyte
2009/6/24
A pilot study was undertaken to investigate the differences in oxidative DNA damage and 2-h DNA repair in peripheral lymphocytes between lung cancer patients and healthy subjects. Twenty-four lung ca...
Genetic Studies of Bone Diseases: Evidence for Involvement of DNA Damage Response Proteins in Bone Remodeling
p53 Atm c-Abl osterix osteoblast osteoporosis
2009/4/20
Bone remodeling is carried out by bone marrow mesenchymal stem cell derived osteoblasts, which form the bones, and hematopoeitic stem cell derived osteoclasts, which absorb the bones. Their actions a...

Au (gold) is a heavy metal and its complexes are one of the more effective medicaments available for rheumatoid arthritis, although many authors have reported serious kidney damage during the chrysoth...
Evaluation of oxidative DNA damage in human sperm and its association with male infertility
8-Hydroxydeoxyguanosine spermatozoa infertility
2009/2/18
Recently, there is increasing evidence suggesting that oxidative sperm DNA damage is closely associated with impaired sperm function and male infertility. 8-Hydroxydeoxyguanosine (8-OHdG) is consi...
An immunochemical assay to detect DNA damage in bovine sperm
immunochemical assay DNA damage bovine sperm
2008/12/25
An immunochemical assay has been developed to detect oxidative damage in bovine sperm DNA. Sperm DNA contains a large amount of oxidative damage as a result of exposure to exogenous agents, but dama...
DNA Damage in Bovine Sperm Does Not Block Fertilization and Early Embryonic Development But Induces Apoptosis After the First Cleavages
Mitotic spindles blastocyst ICSI
2008/12/23
The main goal of this study was to investigate whether and at what level damage of paternal DNA influences fertilization of oocytes and early embryonic development. We hypothesized that posttesticul...
Nickel-Induced Oxidative Stress in Testis of Mice：Evidence of DNA Damage and Genotoxic Effects
