Glomerular filtration rates (GFR) were estimated in 168 children (227 estimates) before treatment for haematological malignancies with high dose, intravenous methotrexate. Clinical management was altered on the basis of GFR in only two cases, both of whom had tumour lysis syndrome. Routine estimations of GFR do not contribute to management.

Dietary protein augmentation elicits an increase in single nephron glomerular filtration rate (GFR) and increased transglomerular pressure. This is similar to the hemodynamic response to reduction in renal mass. Among patients and experimental animals with proteinuric renal disease, these changes also cause an increase in glomerular permselectivity, which in experimental animals accelerates los...

introduction: kidney disease is a major public health challenge worldwide. epidemiologic data suggest a significant relationship between underlying diseases and decrease in glomerular filtration rate (gfr). clinical studies and laboratory research have shown that the mentioned parameter is effective in development and progression of the renal disease per se. in this study, we used learning-base...

1. A highly significant linear correlation was found between glomerular filtration rate and urine flow rate in both freshwater and seawater trout. The percentage tubular reabsorption of water was approximately 33% greater in seawater trout than in freshwater trout. 2. As oxygen consumption increased, the urine flow rate increased in freshwater and seawater rainbow trout. The proportional increa...

Aim: The mortality and morbidity of COVID-19 disease are higher in patients with comorbidities. In this study, we staged chronic renal failure hospitalized the intensive care unit (ICU) aimed to evaluate process according stage failure.
 Material Method: medical records 249 followed Ankara City Hospital MH3 ICU were reviewed retrospectively. divided into three stages their estimated glomer...

We have developed a model of tubuloglomerular feedback (TGF) and the myogenic mechanism in afferent arterioles to understand how the two mechanisms are coupled. This paper presents the model. The tubular model predicts pressure, flow, and NaCl concentration as functions of time and tubular length in a compliant tubule that reabsorbs NaCl and water; boundary conditions are glomerular filtration ...

There is increasing interest in the role of aldosterone in the pathophysiology of hypertension, cardiovascular disease and deteriorating renal function. The aim of this study was to investigate the relationship between aldosterone and the glomerular filtration rate (GFR) in hypertensive patients with preserved renal function. The study involved 186 consecutive hypertensive patients with a GFR >...

Nephrosclerosis can be defined by the presence of glomerulosclerosis, tubular atrophy, interstitial fibrosis, and arteriosclerosis on renal biopsy. Chronic kidney disease is identified clinically by a reduction in glomerular filtration rate (GFR) and has been characterized histologically by nephrosclerosis. Many relatively healthy older adults have been diagnosed with chronic kidney disease bec...

Background: Measurement of glomerular filtration rate (GFR) and monitoring of it in any patient on nephrotoxic drugs is very important. Recently, cystatin C (cys-C) has been introduced as a better marker for determining and monitoring renal function than creatinine especially in a mild decrease of GFR. This study was done to assess the change of GFR measurement based on serum Cys-C and creatini...
