DNA molecules are continuously released through decomposition of organic matter and are ubiquitous in most environments. Such DNA becomes fragmented and damaged (often <100 bp) and may persist in the environment for more than half a million years. Fragmented DNA is recognized as nutrient source for microbes, but not as potential substrate for bacterial evolution. Here, we show that fragmented D...
Positively-charged gold nanoparticles can effectively differentiate long DNA and fragmented DNA, thus providing a simple and visual approach to colorimetric detection of nuclease activity.
With the advance in nanomedicine, the present study was conducted to explore the possible therapeutic role of intravenous nano- hydroxyapatite (nano-HAp) into male rats after chronic exposure to aluminum chloride (AlCl3). This exposure interposed DNA fragmentation, apoptosis, alters oxidant/antioxidant status as well as change in content of neurotransmitters. The rats were injected with 100 mg/...

The application of DNA sequencing technology to the study of ancient DNA has enabled the reconstruction of past epidemics from genomes of historically important plant-associated microbes. Recently, the genome sequences of the potato late blight pathogen Phytophthora infestans were analyzed from 19th century herbarium specimens. These herbarium samples originated from infected potatoes collected...
The occurrence of DNA fragmentation in lymphocytes obtained from alloxan-induced diabetic rats and diabetic patients was investigated. A high proportion of apoptotic lymphocytes in diabetic states may explain the impaired immune function in poorly controlled diabetic patients. Rat mesenteric lymph node lymphocytes were analysed for DNA fragmentation by using flow cytometry and agarose gel, and ...
