Alkali-labile lesion to DNA photosensitized, via an electron transfer mechanism, by three non-steroidal anti-inflammatory drugs (NSAIDs), ketoprofen, tiaprofenic acid and naproxen and their photoproducts during drug photolysis, was investigated using (32)P-end labelled synthetic oligonucleotide. These photooxidative damages were correlated with the photophysical and electrochemical properties o...
Objective(s): The aim of this study was to prepare fraction and determine the biological activities of the polyphenol-enriched fraction of Berberis integerrima Bunge fruits. Materials and Methods: In this assay fraction was extracted by column chromatography, using Amberlite column as the stationary phase. Phenol and flavonoids in the extract and fraction were analyzed by high performance liqui...
Background: One of the major factors affecting on male infertility is oxidative stress (OS). Two main sources of ROS production are leukocytes and spermatozoa. The ROS such as tertiary-butyl hydroperoxide (TBHP) may damage and fragmentate to sperm DNA, which can lead to complications in the offspring. In this study, we will investigate the effect of od on DNA fragmentation index (DFI) in sperm ...
