DNA damage induced by various reactive oxygen species can be characterized using a set of repair endonucleases with defined substrate specificities. DNA damage profiles thus obtained in a cell-free system can be compared with those observed in cellular DNA. Using this approach, we have demonstrated that an illumination of Salmonella typhimurium cells with visible light in the presence of methyl...
in order to find a prophylactic supplementation for individuals who are at risk of exposure to ionizing radiation, we attempted to evaluate the effect of vitamin e (vit-e), a biological free radical scavenger, on restoration of hepatic lipid peroxidation (lpo) and lipid profile (lp) changes induced by sublethal g- radiation in balb/c mice. the concentrations of cholesterol and phospholipid were...
This paper outlines the historical development of the wheel and rail profiles currently used on railway vehicles. It also presents the key damage mechanisms involved in wheel-rail contact and summarises the methods that have recently been developed by railway engineers to predict the level of wheel and rail damage from these mechanisms. Tools for predicting the key damage modes of wear and roll...
BACKGROUND Cardiovascular risk assessment in the clinical practice is mostly based on risk charts, such as Framingham risk score and Systemic Coronary Risk Estimation (SCORE). These enable clinicians to estimate the impact of cardiovascular risk factors and assess individual cardiovascular risk profile. Risk charts, however, do not take into account subclinical organ damage, which exerts indepe...
