FILTRATION IN GLOMERULUS
1. One of the capillary networks that are part of the renal corpuscles in the nephrons of the kidney. Each is surrounded by a Bowman's capsule, the site of renal (glomerular) filtration, which is the first step in the formation of urine. See: illustration
2. A group of twisted capillaries or nerve fibers.

olfactory glomerulus

A neural network found in the olfactory bulb, formed by the dendrites of mitral cells intertwined with the axons of olfactory receptor cells.

Glomeruli (singular, glomerulus)

Tiny tufts of capillaries which carry blood within the kidneys. The blood is filtered by the glomeruli. The blood then continues through the circulatory system, but a certain amount of fluid and specific waste products are filtered out of the blood, to be removed from the body in the form of urine.

Therefore, each tissue fragment was randomly collected by the nephrologist and blindly provided to the other veterinarians to quantify the number of glomeruli in each sample using the methods listed below.
Histological observations: Shrunken glomeruli were observed in groupDI and DII.
In the glomeruli, this receptor seems to be present in all major renal cells, including mesangial cells, endothelial cells, and podocytes.
Data were previously obtained by 12 pathologists, who reviewed 315 JPEG images of individual glomeruli (equivalent to assessing the glomerular profile on a single biopsy level) and recorded the presence or absence of 51 glomerular descriptors using an electronic scoring matrix (Figure 1, A).
In joint research with the Graduate School of Medicine at Kyoto University, this technology was applied to the detection of glomeruli in kidney biopsy images.
(2) reported six patients with more than 50% crescents of glomeruli. The histological features and clinical response to aggressive immunosuppressive treatment resembled AAV.
have shown that miR-29a was downregulated in the glomeruli from diabetic mice and that miR-29a overexpression attenuated nephrin downregulation, podocyte apoptosis, and proteinuria.
Both strains showed 20-22% segmentally sclerosed glomeruli on days 7, 21, and 42 and developed increased globally sclerosed glomeruli over time (2% on day 7 and 13% on day 42 (Table 1)).
In addition, due to the proliferation of these cells, some glomeruli were found to be larger, with decreased Bowman's space.
In 2010, an international consortium of renal pathologists and nephrologists proposed a histopathological classification schema for ANCA-GN, which consisted of four histological classes: focal ([less than or equal to] 50% normal glomeruli), crescentic ([less than or equal to] 50% glomeruli with cellular crescents), mixed (<50% normal/crescentic/globally sclerotic glomeruli), and sclerotic ([less than or equal to] 50 globally sclerotic glomeruli) [14].
Because this disease state is often accompanied by immunoglobulin A (IgA) deposits in glomeruli, it is also termed hepatic IgA nephropathy.
