A brush border (striated border or brush border membrane) is the microvillus-covered surface of simple cuboidal and simple columnar epithelium found in different parts of the body. Microvilli are approximately 100 nanometers in diameter and their length varies from approximately 100 to 2,000 nanometers.
The proximal tubule is the segment of the nephron in kidneys which begins from the renal pole of the Bowman's capsule to the beginning of loop of Henle.At this location, the glomerular parietal epithelial cells (PECs) lining bowman’s capsule abruptly transition to proximal tubule epithelial cells (PTECs).
Thousands of microvilli form a structure called the brush border that is found on the apical surface of some epithelial cells, such as the small intestines. (Microvilli should not be confused with intestinal villi, which are made of many cells. Each of these cells has many microvilli.)
The adult human kidney contains at least 26 distinct cell types, [25] including epithelial, endothelial, stromal and smooth muscle cells. Distinct cell types include: Kidney glomerulus parietal cell; Kidney glomerulus podocyte; Intraglomerular mesangial cell; Extraglomerular mesangial cell; Juxtaglomerular cell; Kidney proximal tubule brush ...
Nephritis can often be caused by infections and toxins, but it is most commonly caused by autoimmune disorders that affect the major organs like kidneys. [5] Pyelonephritis is inflammation that results from a urinary tract infection that reaches the renal pelvis of the kidney. [6]
The Mayo Clinic diet, a program that adheres to this notion, was developed by medical professionals based on scientific research, so you can trust that this program is based on science, and not ...
Sterile pyuria: white blood cells and no bacteria. About 50% of patients with AIN have pyuria. [21] Nephrotic-range amount of protein in the urine may be seen with NSAID-associated AIN. Low grade proteinuria may be seen in a majority of other causes of AIN. [21] White blood cell (WBC) casts: Fewer than one in five patients with AIN have WBC ...
