Reabsorption

 

reverse absorption of water and substances dissolved in it from primary urine flowing through the renal tubules; the final urine thus produced is excreted from the body. Among the essential substances that are reabsorbed are many amino acids, vitamins, and most Na+, K+, and Ca2+ions. The reabsorption of some substances varies with their concentration in the blood. For example, glucose is completely reabsorbed if its concentration in plasma is no more than 150–180 mg percent. At high concentrations, some of the glucose enters the urine (glucosuria).

The SGLT-2 inhibitors reduce renal glucose reabsorption, leading to a lower plasma glucose concentration.
In BS, defective sodium and potassium reabsorption in the TAL results in reduced calcium reabsorption and excessive delivery of calcium to more distal parts of the nephron.
This also has an embryological explanation: It is the closest portion between both Muller ducts and the point where the fusion and reabsorption processes between both start before simultaneously proceed cranially and caudally.
Among mammalian AQPs (AQPO-14), AQP2 is the only AVP-dependent water channel that facilitates water reabsorption in response to AVP, by translocating from intracellular vesicles to the apical membrane of collecting duct principal cells (Sasaki, 2012; Kortenoeven and Fenton, 2014).
Taiwan would accept reabsorption and this would simultaneously "mean that China was on a par with the United States as a global superpower.
These babies were evaluated at the 40th gestational week and serum calcium, phosphorus, alkaline phosphatase, urea, creatinine, urinary calcium and phosphorus levels were measured and tubular reabsorption of phosphorus was determined.
1, 25-dihyroxycholecalciferol then exerts its effects on the (1) intestine to increase calcium absorption, (2) bone to increase resorption, and (3) kidneys to increase reabsorption by the proximal tubules.
The Society identified seven basic groups according to Mullerian development and their relationship to fertility: agenesis and hypoplasias, unicornuate uteri (unilateral hypoplasia), didelphys uteri (complete nonfusion), bicornuate uteri (incomplete fusion), septate uteri (nonreabsorption of septum), arcuate uteri (almost complete reabsorption of septum), and anomalies related to fetal DES exposure.
Sodium-glucose co-transporter 2 (SGLT2) inhibitors are a new class of oral antidiabetic medications that act by reducing renal glucose reabsorption in the proximal convoluted tubule thus leading to increased glycosuria and lowering of blood glucose.
The researchers showed that FGF23 has a so called sodium conserving effect, meaning it controls the reabsorption of filtered sodium in the kidneys.
A separate study conducted on rats found that moderate sugar intake may fuel a reaction that leads to increased salt reabsorption by the kidneys, which may damage the kidneys over time, as well as contribute to high blood pressure.
