Radionuclidic techniques may provide assessment of glomerular filtration rate (GFR) effective renal plasma flow (ERPF) or individual renal function. Several agents were available for determination of these parameters such as ¹³¹I-OIH (O-iodohippurate) and different derivatives of DADS (Diamidodisulfur). OIH has the disadvantage of imparting a relatively high absorbed radiation dose to the...
در این پایان نامه تحلـیل عددی میدان سرعت و انتقال جرم برای جریان مغشوش در خم های 90 درجه انجام شده است. مدل rng k-e به عنوان مدل اغتشاش که مناسب برای جریان های چرخشی است, استفاده شده است. ابتدا معادلات پیوستگی و مومنتوم برای زانویی سه بعدی حل شده و مقادیر سرعت در مقاطع مختلف خم بدست آمد. نتایج حاصل نشان می داد که به علت وجود نیروی گریز از مرکز در خم, سیال کندتر در نیمه بالا و پایین لوله به سمت ...
In this case report we present a 49 year old man with history of a mass in right upper quadrant and microscopic hematuria who referred to the hospital 2 months ago. In sonography, one cystic mass with multiple irregular septa in upper segment of right kidney and in CT scan, a multiloculated cystic mass in anterior of right kidney was reported. Under light microscopic examination the ...
The kallikrein kinin system (KKS) is involved in arterial and renal functions. It may have an antihypertensive effect in both essential and secondary forms of hypertension. The role of the KKS in the development of two-kidneys, one-clip (2K1C) hypertension, a high-renin model, was investigated in mice rendered deficient in tissue kallikrein (TK) and kinins by TK gene inactivation (TK-/-) and in...
OBJECTIVES To identify the frequency of the Acute Kidney Injury and to compare the application of the AKIN classification with the separate use of the serum creatinine in the postoperative period of cardiac surgery. METHODS This study was prospectively developed in a teaching and specialized research hospital in cardiology of the public health system of the state of São Paulo. Forty-four pati...
In renal disease, mechanisms available to compensate for the reduced haemoglobin levels associated with anaemia include increased oxygen extraction from peripheral tissues and, primarily, increased blood flow and changes in blood flow distribution. Haemodynamic changes induced by anaemia include decreases in blood viscosity, peripheral vascular resistance and oxygen delivery, and an increase in...
a project was established to develop a procedure for the selection, design, installation, test and evaluation of mass-flow rate measurement systems for root crop harvesting and to assess the consistency and precision of the weighing systems incorporated into crop feed arrangements in both laboratory and field studies. studies were conducted to evaluate conveyor belt weighing systems using an ex...
this work concerns the peristaltic flow of a williamson fluid model in an inclined asymmetric channel under combined effects of heat and mass transfer. the governing nonlinear partial differential equations are simplified under the lubrication approach and then solved analytically and numerically. the analytical results are computed with the help of regular perturbation and the numerical result...
