Researchers create ultra-sensitive assay to detect DNA damage caused by ionizing radiation and cancer-causing chemicals, showing potential for early detection and treatment of genetic injuries. The new technique is 10,000 to 100,000 times more sensitive than existing methods.
Researchers used a novel test to measure damaging activity of free radicals in body tissues, finding high levels in atherosclerotic plaque tissue. The technique provides a real handle on oxidant processes in atherogenesis and could lead to clinical studies testing efficacy of drugs limiting free-radical damage.
A new study suggests that inhibiting poly(ADP-ribose) polymerase (PARP) enzyme may protect nerve cells from energy loss and prevent irreversible damage after a stroke. The research, published in Nature Medicine, found that genetically modified mice without the PARP gene experienced reduced brain damage compared to unaltered mice.
Researchers found that C-peptide protein repaired damaged blood vessels and nerves in diabetic rats, suggesting a new approach to preventing cardiovascular disease in both types of diabetes. The protein's unique mechanism of action may be key to understanding its effects on cell function.
