BACKGROUND NGAL is involved in modulation of the inflammatory response and is found in the sera of uremic patients. We investigated whether hemodiafiltration (HDF) could influence the ability of polymorphonuclear granulocytes (PMGs) to release NGAL. The involvement of interleukin- (IL-)1β and tumor necrosis factor- (TNF-)α on NGAL release was evaluated. METHODS We studied end-stage renal dise...
We present a model-independent method of quantifying galaxy evolution in high-resolution images, which we apply to the Hubble Deep Field (HDF). Our procedure is to k-correct all pixels belonging to the images of a complete set of bright galaxies and then to replicate each galaxy image to higher redshift by the product of its space density, 1/Vmax, and the cosmological volume. The set of bright ...
We have studied topology of the distribution of the high redshift galaxies identified in the Hubble Deep Field (HDF) North and South. The two-dimensional genus is measured from the projected distributions of the HDF galaxies at angular scales from 3.8 to 6.1. We have also divided the samples into three redshift slices with roughly equal number of galaxies using photometric redshifts to see poss...
Increasing evidence suggests that treatment with online post-dilution haemodiafiltration (HDF) improves clinical outcome in patients with end-stage kidney disease, if compared with haemodialysis (HD). Although the primary analyses of three large randomized controlled trials (RCTs) showed inconclusive results, post hoc analyses of these and previous observational studies comparing online post-di...
BACKGROUND: The high incidence of cardiovascular disease in patients with end stage renal disease (ESRD) is related to the accumulation of uremic toxins in the middle and large-middle molecular weight range. As online hemodiafiltration (HDF) removes these molecules more effectively than standard hemodialysis (HD), it has been suggested that online HDF improves survival and cardiovascular outcom...
مقدمه: سرطان معده یکی از عوامل مهم بیماری و مرگ و میر در جهان است. گونه های گیاهی منحصر به فرد زیادی وجود دارد که برای یافتن ترکیبات ضد سرطانی باید مطالعه شوند. هدف: در این تحقیق، خاصیت ضد سرطانی عصاره اتانولی و آبی گل محمدی بر رده سلولهای سرطانی معده انسان (ags) بررسی شد. روش بررسی: هشت غلظت متفاوت از عصاره ها به همراه داروی 5- فلورواوراسیل بر روی رده سلولی سرطان معده اعمال شد. سمّیت عصاره ها ب...
Background and purpose: The purpose of this study was to evaluate the effect of mouse embryonic fibroblast cells conditioned medium on resumption of meiosis, in vitro maturation of immature mouse oocytes, fertilization and derived embryos development. Material and Methods: Immature oocytes denuded at the germinal vesicle (GV) stage were obtained from female NMRI mice 46-48 hrs after injecti...
Online hemodiafiltration (OL-HDF), first described in 1985, is today a widely prescribed treatment modality for end-stage chronic kidney disease (CKD) patients. Other than in the United States, prescription of the treatment modality is widespread with a steady increase since its inception. Indeed, in Western Europe, more CKD patients receive OL-HDF than peritoneal dialysis, hitherto the second ...
مقدمه: سلول های بنیادی بعنوان یک درمان بالقوه برای ضایعات نخاعی بوده و انواع متعددی از سلول های بنیادی در مدل های حیوانی و انسانی ارزیابی شده اند. سلول های پرتوان القائی با فراهم کردن امکان پیوند سلول از رده سلولی خود بیماربعنوان یک منشا سلولی جالب توجه برای سلول درمانی در طب ترمیمی مطرح می باشد. دراین مطالعه، پتانسیل پیوند دو نوع سلول پیش ساز عصبی و پیش ساز اولیگودندروسیت مشتق شده از سلول های ...
BACKGROUND Middle molecular weight uraemic toxins are considered to play an important role in vascular dysfunction and cardiovascular outcomes in end-stage renal disease (ESRD) patients. Recent dialysis techniques based on convection, specifically high-efficiency on-line haemodiafiltration (HDF), enhance the removal of middle molecular weight toxins and reduce all-cause mortality in haemodialys...
