Introduction: Nephropathy is defined as rational loss of renal function related with glomerulosclerosis and declining glomerular filtration rate. Inflammation and oxidative stress play a critical role in nephropathy. Plantago major has antioxidant effects. The aim of present study is the investigation of the effect of Plantago major hydro-alcoholic extract on the oxidative stress and renal func...
Background: To determine mean prothrombin time and activated partial thromboplastin time in patients of end stage renal disease having normal baseline coagulation parameters after hemodialysis. Methods: In this cross sectional study 84 patients ,16-70 years of age, with end stage renal disease were selected. Prothrombin Time (PT) and Activated Partial Thromboplastin Time (APTT) were performed p...
Kidney transplantation is the key for patients with end-stage renal disease, improving quality of life and longer survival. However, kidney transplant triggers an intense inflammatory response and alters the hemostatic system, but the pathophysiological mechanisms of these changes are not completely understood. The aim of this cross-sectional cohort study was to investigate hemostatic biomarker...
STUDY OBJECTIVES To assess the feasibility of estimating intestinal transit time in the general population using self recorded data on stool form, frequency of defecation, and the interdefecatory time interval. DESIGN Prospective measurement of bowel function. SETTING Bristol, Avon, UK between 1987 and 1989. SUBJECTS Subjects were drawn from 1897 people who comprised 72.2% of a stratified...
چکیده روش های متعددی برای برآورد رواناب حاصل از بارش در حوضه های آبریز وجود دارد. یکی از این روش ها استفاده از مدل های هیدرولوژیکی است. با استفاده از مدل های هیدرولوژیکی و شبیه سازی فرآیندهای هیدرولوژیکی می توان با صرف کمترین زمان و هزینه، رواناب و مولفه های دیگر چرخ? هیدرولوژیکی را برآورد کرد. از آنجا که در حوضه های آبریز اندازه گیری تمام کمیت های مورد نیاز برای تحلیل رواناب ممکن نیست، انتخاب...
Assessment of transit through the gastrointestinal tract provides useful information regarding gut physiology and patho-physiology. Although several methods are available, each has distinct advantages and limitations. Recently, an ingestible wire-less motility capsule (WMC), similar to capsule video endoscopy, has become available that offers a less-invasive, standardized, radiation-free and of...
BACKGROUND Colonic transit tests are used to manage patients with Functional Gastrointestinal Disorders. Some tests used expose patients to ionizing radiation. The aim of this study was to compare novel magnetic resonance imaging (MRI) tests for measuring orocecal transit time (OCTT) and whole gut transit time (WGT), which also provide data on colonic volumes. METHODS 21 healthy volunteers pa...
