| Glucose normally is filtered by the glomerulus, but it is almost completely reabsorbed in the proximal tubule. |
|
| The sarcoplasmic membrane returns to its resting electrical potential, as does the entire T tubule system and the SR membrane. |
|
| If the spermatozoa showed no motility, a new tubule closer to the testis was selected, and the process was repeated. |
|
| The primitive germinal cells are the spermatogonia, which lie peripherally in the tubule wall, outside the barrier of Sertoli cell junctions. |
|
| These structures are not considered to be part of the nephron, but are part of the uriniferous tubule. |
|
| The functional unit in the kidney of all vertebrates is the uriniferous tubule comprising a nephron and a collecting tubule. |
|
| It consists of an end sac, a straight proximal tubule, a short distal tubule, and a raised nephropore, all in the scape of the chelifore. |
|
| The proximal tubule is the site of most secretion, reabsorption, and active transport. |
|
| This influence, along with the specialized receptors along the tubule, allows each tubular section a selective resorptive and secretory function. |
|
| These elements become trapped into the protein matrix as it coagulates within the tubule. |
|
| As an antidiuretic hormone, vasopressin acts on the renal tubule at low plasma concentrations. |
|
| In the distal tubule and collecting duct of the kidney, vasopressin stimulates water resorption so that concentrated urine is produced. |
|
| An efferent cuticular tubule, or duct, leads out of the end of the vesicle towards the center of the secretory lobe. |
|
| Global renal failure always involves a decrease in the glomerular filtration rate and depending on the cause impairment of tubule function. |
|
| Females on the top dose displayed increased incidence of renal tubule calcification. |
|
| In each nephron, a network of tiny blood vessels called the glomerulus attaches to a small tubule. |
|
| An example will be tooth brushing with a toothpaste and the creation or removal of a smear layer overlying the tubule orifice. |
|
| The filtrate, urine, leaves the nephron through a long tubule and collecting duct. |
|
| The tooth wear process results in larger diameter tubule openings as the wear lesion deepens. |
|
| Some examples of toxic effects are acute lethality, loss of hearing, renal tubule necrosis, and cardiomyopathy, to name just a few. |
|
|
|
| The second and third phases take place in the distal tubule, where monobasic phosphate and ammonium salts are formed. |
|
| The role of the Sertoli cells is to nourish the developing and maturing germinal cells which are eventually released into the lumen of the tubule as spermatozoa. |
|
| Thiazide and thiazide-like agents act on the distal convoluted tubule. |
|
| When red blood cell casts are observed in the urine, the glomerular basement membrane or the epithelial lining of the renal tubule may be injured. |
|
| Blocking the dentinal tubules should reduce or stop any movement of fluid in the tubule. |
|
| He does this by crashing the first tubule into the second, bending the latter double, and causing it to bond with the bead. |
|
| Following the postmeiotic phase, spermatozoa are released into the lumen of the seminiferous tubule of the testis and transported to the epididymis for storage. |
|
| The basic functional unit of the kidney is the uriniferous tubule. |
|
| These cells form a well ordered, isolatable BB that is morphologically and compositionally comparable to those from the proximal tubule epithelial cell. |
|
| Cells of the nephron tubule may secrete nitrogenous wastes into the urine and reabsorb water and nutrients. |
|
| Stage IV begins with the presence of spermatids and a few spermatozoa in the tubule lumen. |
|
| Mature spores have a dense exospore coat, a pale endospore, and single rows of 8-11 polar tubule coils. |
|
| The evaluation of cell population was based on the calculation made for each cell type per cross section of the seminiferous tubule. |
|
| Seasonality was determined by changes in relative and total testis weight, and in seminiferous tubule diameters. |
|
| Seminiferous tubule diameter measurement was carried out using a linear scale-ocular micrometer inserted into the eyepiece. |
|
| The extent of potassium loss depends on the concentration gradient across the tubule walls. |
|
| Following the proximal convoluted tubule is the loop of Henle, which descends into the medulla and then runs straight up again to the cortex where it continues as the distal convoluted tubule. |
|
| The proximal tubule is one of the most important parts of the kidney filtration system as it plays a key role in reabsorbing vital components such as sodium and other ions, water, glucose, and amino acids back into the blood. |
|
| Architectural similarity exists between the adult teleost hepatic tubule, the exocrine pancreatic acinus, and elements of the fetal and juvenile forms of mammalian liver. |
|
| The spermatogonia mature into spermatocytes, which mature into spermatids that mature into spermatozoa as they move into the central lumen of the seminiferous tubule. |
|
|
|
| Taken together, these results suggest that, at the levels of uranium intake observed in this study, the segment of the nephron most at risk to injury is the proximal tubule, rather than the glomerulus. |
|
| Endocytosis in proximal tubule cells involves a two-phase membrane-recycling pathway. |
|
| Tubules and DNA strands are mixed together in solution, and biochemical processes are then used to attach one end of each DNA strand to a tubule, and the other end to a glass sheet. |
|
| The first tubule then continues on its way. |
|
| Constriction around the center of a mitochondrial tubule leads to the formation of smaller fragments, and fusion between two organelles allows the mixing of their contents. |
|
| These and two others showed minimal to moderate tubule injury. |
|
| Again, however, this would require the wear to open the tubule system. |
|
| Low incidences of uncommon tumours, such as preputial gland carcinomas, Zymbal gland carcinomas in males and renal tubule adenomas in both sexes, were also suspected of being related to exposure. |
|
| In contrast to its benign profile in the proximal tubule, ceftobiprole medocaril shows dose-related adverse effects in the distal tubule and collecting duct. |
|
| The trend to reduction in the non-renal clearance of meropenem seen when meropenem was coadministered with probenecid implies that the proximal renal tubule may be involved in the metabolism of meropenem. |
|
| Metolazone interferes with the renal tubular mechanism of electrolyte reabsorption and acts primarily to inhibit sodium reabsorption at the cortical diluting site of the distal segment and in the proximal convoluted tubule. |
|
| Impaired water permeability and adenylate cyclase responsiveness of the cortical collecting tubule to vasopressin. |
|
| Amiloride and triamterene interfere with the sodium-potassium exchange at the distal convoluted tubule of the kidney. |
|
| They may mediate the transfer of information during renal tubule hypertrophy after nephron loss. |
|
| Figure 3 is an electron micrograph of a renal tubule epithelial cell showing a distinct intranuclear inclusion. |
|
| The primary spermatocyte is the largest of the germ cells in the tubule, and the various stages are distinguished based on the degree of chromosome coiling. |
|
| There was no evidence of other proximal tubule dysfunction, as evidenced by the absence of glucosuria, phosphate wasting, bicarbonate wasting, or metabolic acidosis. |
|
| Tubule adhesion forces were similar for the holothuroid species examined here. |
