background: in response to the need for diagnosis and treatment, medical radiation has been increasingly used worldwide. this study investigated the medical utilization of radiation-related diseases among radiological technologists (rts) and factors that influence such diseases. materials and methods: data were collected from the taiwan national health insurance research database. a panel study...

Background and Objective: Numerical modeling of biological structures would be very helpful tool to analyze hundreds of human body phenomena and also diseases diagnosis. One physiologic phenomenon is blood circulatory system and heart hemodynamic performance that can be simulated by utilizing lumped method. In this study, we can predict hemodynamic behavior of one artery of circulatory system (...

Introduction: This report presents 2011-2012 data on leading causes of death in the Islamic Republic of Iran by Province. Methods: Data in this report are based on information from all death certificates filed in the 31 provinces in 2011-2012 . Causes of death classified by the International Classification of Diseases, Tenth Revision (ICD–10) are ranked a...

High-dose ionising radiation is associated with circulatory disease. Risks associated with lower-dose (<0.5 Gy) exposures remain unclear, with little information on risk modification by age at exposure, years since exposure or dose-rate. Tuberculosis patients in Canada and Massachusetts received multiple diagnostic x-ray fluoroscopic exposures, over a wide range of ages, many at doses <0.5 Gy. ...

in this study a new minimum lumped electrical model of total circulatory system through numerical solutions to approximate the response of the human circulatory system was presented. among five existent ventricular elastances as activity function of heart pumps, a more accurate model was chosen as well as the operation of baroreflex system to accommodate variations in heart rate and systemic va...

The aim of this study was to analyze the association between the exposure to fine particulate matter and circulatory disease mortality rates in the elderly living in the Brazilian Amazon. An ecological study of circulatory disease, acute myocardial infarction and cerebrovascular disease mortality rates in micro areas of the Brazilian Amazon was carried out. The environmental exposure indicator ...
