Ionizing radiation is the most established risk factor for meningioma formation. Our aim was to evaluate the main effect of selected candidate genes on the development of meningioma and their possible interaction with ionizing radiation in the causation of this tumor. The total study population included 440 cases and controls: 150 meningioma patients who were irradiated for tinea capitis in chi...

external exposed radiation may play an important role in pathogens of irritable bowel syndrome (ibs), although is thought to arise due to a combination of genetic and environmental factors. the result is dysregulated immune responses due to alteration in the gut microbiota population and the subsequent development of gut inflammation. it has recently been shown that the effect of ionizing radia...

models can be used to predict crop yield and inputs levels such as fertilizer, in order to conduct programming for the management of probable future crisis. in this study, based on the model, the effect of nitrogen fertilizer on dry matter partitioning in shoot and root of sugar beet was predicted. for model construction, data were collected from an experiment conducted in karaj city in 2001. i...
