Objective Chronic unpredictable stress (CUS) can influence the risk and progression of cancer through increased oxidative stress. Quercetin (QU), a phytochemical found in daily foods, has been extensively studied as a chemopreventive agent against various types of cancers. Our aim was to investigate the role of CUS on the efficacy of QU against DMBA+TPA (7, 12-dimethylbenz (a) anthracene+12-O-Tetradecanoylphorbol-13-acetate)-induced skin carcinogenesis. Methods Eighty-four adult male Swiss albino mice were randomly divided into seven groups (12 mice/group) based on different treatments and killed after 16 weeks. Blood and skin tissues were collected for biochemical estimations, DNA damage...

Abstract: Introduction: The use of stem cell has opened new avenues in the management and cure of diseases in modern era. They have enabled us to achieve remissions and cure in malignancies. They have enormous ability of stimulating the repair process in diseased and damaged tissue. As the medical specialists are a reliable source of information, so their knowledge and approach are vital in counselling the patients regarding the use of stem cells as an advanced treatment option. Aim: To assess the knowledge and attitude level about stem cells and their therapeutic applications among medical undergraduates. Materials and Methods: This cross-sectional study was carried out for a period of six...
