conclusions presence of cae in patients with cas increases its cardiovascular event rate. isolated cae is not a benign finding and mi can occur. risk factors of cae are similar to cas, but c/s is more associated with cae than cas. dm is seen in cae patients less than cas. results hypertension (htn), dyslipidemia (dlp), and male sex were matched in both groups without significant difference. cig...

background: cardiovascular disease (cvd) is the cause of one third of deaths worldwide and this will progress because of increasing cvd's risk factors. the most basic task of dealing with the epidemic of cvd is primary prevention of risk factors. as atherogenic index of plasma (aip) is a strong marker to predict the risk of atherosclerosis and coronary heart disease, we assessed the correlation...

background: more than 250,000 people die annually of pancreatic cancer, worldwide. the highest incidence and mortality rates of pancreatic cancer are reported in developed countries. in developing countries the rate have been stabilizing over the past two decades but in countries which rates have been low for decades is now increasing. recognizing pancreatic cancer's risk factors and its preven...

background when a primary radiation interacts with a medium, the secondary radiations are produced, that the contribution of these secondary radiation should considered in the calculation of dose. build-up factor is a dosimetric correction factor to assume effect of secondary radiation in calculation of dose. calculation of this factor is very difficult and time consuming. due to significance o...
