The goal of this study was to investigate LRP1 expression in different nephron segments in healthy and diseased human renal tissue as well as the developing kidney. (asn-online.org)
Each nephron consists of a ball formed of small blood capillaries, called a glomerulus, and a small tube called a renal tubule. (onteenstoday.com)
Each nephron has a glomerulus to filter your blood and a tubule that returns needed substances to your blood and pulls out additional wastes. (onteenstoday.com)
Excretory pathway in kidney - Blood is carried by the renal artery to the nephron from there to renal pyramid leading to pelvis to the ureter, then to the urinary bladder and finally to the urethra which passes it to outside. (onteenstoday.com)
These include an increase of salt reabsorption via the Na(+),Cl(-)-cotransporter (NCC) of the distal convoluted tubule (DCT), which minimizes electroneutral K(+) loss in downstream nephron segments. (mdc-berlin.de)
Despite significant advances in understanding nephron segment patterning, many questions remain about the underlying genes and signaling pathways that orchestrate renal progenitor cell fate choices and regulate differentiation. (mdpi.com)
Each nephron consists of two parts: a renal corpuscle (also known as a glomerulus) that filters the blood, and a renal tubule that reabsorbs substances that are needed and eliminates unneeded substances in urine. (medlineplus.gov)
Examination of USAG-1 expression in developing kidney indicated that a mosaic of proximal and distal tubule marker-positive cells reside side by side in the immature nephron. (ox.ac.uk)

Serum creatinine is reflective of glomerular filtration rate (GFR) under steady-state conditions but has less utility in the context of decreasing kidney function. (medscape.com)
Creatinine clearance is a good measure of filtration rate because creatinine (a waste product of the body) is filtered from the blood but is not reabsorbed by the tubules. (healthpages.org)
As I shall show later on, lasix and lisinopril could have raised her risk for kidney damage from crystals, the former because of increased proximal tubule reabsorption , the latter because of reduced glomerular filtration rate . (uchicago.edu)

That paper described calcium deposits in kidneys of patients with hyperparathyroidism - a mineral disorder caused by enlargement of one or more parathyroid glands. (uchicago.edu)
All of his patients suffered from primary hyperparathyroidism, a disease found in only 5% or so of calcium stone formers we see today in our clinics. (uchicago.edu)
As a result Albright coined the word nephrocalcinosis to describe the scarred, contracted kidneys of patients whose primary hyperparathyroidism had caused kidney disease. (uchicago.edu)
Because of the lack of consistently effective treatment for primary focal segmental glomerular sclerosis, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers are commonly used for patients with mild disease to control symptoms. (basicmedicalkey.com)

Kidney function ( eGFR ) measured casually in the course of ordinary health care was stable and normal from 2010 through 2014, and had been, presumably, since 2000. (uchicago.edu)
Stage 2 kidney disease is defined as an eGFR between 60 to 89 milliliters per minute, and stage 3 kidney disease is defined as an eGFR between 30 and 59 milliliters per minute. (drprincetta.com)
A total of 334 subjects with T2DM who enrolled in a disease management program were included in this study and stratified according to eGFR. (medsci.org)

In most cases, there will be a solitary tumor in one kidney, but 5-13% of children have bilateral tumors and 10% have multifocal tumors in a single kidney. (medscape.com)
A CT scan of the abdomen confirms the renal origin of the tumor and determines the presence of bilateral tumors. (medscape.com)
The tumors may be large, and their size may make it difficult to identify its renal origin on sonograms. (medscape.com)
