Whether changes in renal blood flow (RBF) are associated with and possibly contribute to cystic disease progression in autosomal dominant polycystic kidney disease (ADPKD) has not been ascertained. The Consortium for Radiologic Imaging Studies of Polycystic Kidney Disease (CRISP) was created to develop imaging techniques and analyses to evaluate progression. A total of 131 participants with ear...
BACKGROUND Accurate measurement of renal function in cirrhotic patients is still challenging. To find the best test for the determination of the true glomerular filtration rate (GFR) in cirrhotic patients this study prospectively compared measured (m)GFR, the gold standard, with estimated (e)GFR using equations based on serum levels of creatinine and cystatin C. METHODS GFR was measured by si...
Limited prospective data are available on the importance of estimated glomerular filtration rate (GFR) and proteinuria in the prediction of all-cause mortality (ACM) in community-based elderly populations. We examined the relationship between GFR or proteinuria and ACM in 949 randomly selected community-dwelling elderly subjects (aged ≥65 years) over a 5-year period. A spot urine sample was use...
The use of outpatient laboratory databases to identify people with a low GFR may be part of an effective strategy to increase their use of treatments to prevent kidney failure. All renal function data from 17 independent outpatient laboratories in Eastern Ontario were combined to determine the proportion of adults with at least one serum creatinine measurement during a 1-yr period. The detectio...
The Schwartz formula was devised in the mid-1970s to estimate GFR in children. Recent data suggest that this formula currently overestimates GFR as measured by plasma disappearance of iohexol, likely a result of a change in methods used to measure creatinine. Here, we developed equations to estimate GFR using data from the baseline visits of 349 children (aged 1 to 16 yr) in the Chronic Kidney ...
Objective. This study was set to assess the effect of renal dysfunction on outcome of stroke patients treated with intravenous thrombolysis (IVT). Methods. This multicenter research involved 403 patients from January 2009 to March 2015. Patients were divided into two groups: (1) control group with GFR ≥ 45 mL/min/1.73 m2 and (2) low GFR group with GFR < 45 mL/min/1.73 m2. Outcome measurements w...
چکیده: هدف: این مطالعه به منظور ارزیابی اثر اسانس گیاه مریم گلی در جلوگیری از آسیب های ناشی از ایسکمی - خون رسانی مجدد کبد در قلب و کلیه انجام گردید. روش کار: در این مطالعه از 48 سر موش صحرایی نر اسپراگن- دولی با وزن و سن تقریباً یکسان که در شرایط محیطی و تغذیه ای همگون نگهداری می شدند استفاده گردید. این حیوانات به صورت تصادفی به 3 گروه به شرح زیر تقسیم شدند: 12 سر به عنوان گروه درمان، 12 سر...
UNLABELLED Glomerular filtration rate (GFR) can accurately be determined using (51)Cr-ethylenediaminetetraacetic acid (EDTA) plasma clearance counting but is time-consuming and requires technical skills and equipment not always available in imaging departments. (68)Ga-EDTA can be readily available using an onsite generator, and PET/CT enables both imaging of renal function and accurate camera-b...
تخلیه پسابهای ناشی از فعالیتهای کشاورزی و صنعتی در منابع آب سطحی، باعث پایین آمدن کیفیت آب می شود. فسفات و نیترات از جمله عوامل آلوده کننده موجود در این پسابها می باشند. استفاده از صدف برای حذف این عوامل از جمله روشهای تصفیه بیولوژیکی است. صدف آنودونتا سیگنه آ (anodonta cygnea) در میان صدفهای آب شیرین، یکی از انواع مهم صدفهای فیلتر کننده می باشد. هدف اصلی انجام این پژوهش، بررسی میزان جذب ذرات م...
Glomerular filtration rate (GFR), renal plasma flow (RPF), and electrolyte excretion were studied in 17 patients subjected to salt depletion and loading. Salt depletion led to maximal renal salt conservation with the average GFR and RPF slightly decreased. Salt loading produced increased excretion of sodium and chloride with the average GFR and RPF slightly increased. Since the decreased electr...
