reabsorption

 [re″ab-sorp´shun]
1. the act or process of absorbing again, as the absorption by the kidneys of substances that were already secreted into the tubules, such as glucose, proteins, or sodium.

reabsorption

/re·ab·sorp·tion/ (re″ab-sorp´shun)
1. the act or process of absorbing again, as the absorption by the kidneys of substances (glucose, proteins, sodium, etc.) already secreted into the renal tubules.

reabsorption

[rē′əbsôrp′shən]
the process of something being absorbed again, such as the removal of calcium from the bone back into the blood. Also called resorption.

reabsorption

The flow of glomerular filtrate from the proximal tubule of the nephron into the peritubular capillaries, which allows the selective passage of certain substances (glucose, proteins, sodium) back into the circulation.

reabsorption

Physiology The selective passage of certain substances–glucose, proteins, sodium–back into the circulation after it had been secreted into the renal tubules. See Countertransport.

Indeed, thiazides are used in hypercalciuric stone formers because they slightly volume-deplete patients and secondarily increase sodium, chloride, and calcium reabsorption in the TAL.
Nevertheless, the kidney of adult anurans shows significant antidiuretic responses to AVT: a decreased glomerular filtration rate and/or an increased water reabsorption across the renal tubule (Henderson et al.

The level of tubular reabsorption of phosphorus was compared with the serum calcium, phosphorus and alkaline phosphatase levels measured at the 40th gestational week and alkaline phosphatase was found to be significantly increased in the group with a high tubular reabsorption of phosphorus ([greater than or equal to]%95).
Anomalies also can be categorized in terms of progression along the developmental continuum, taking into account that many cases result from partial failure of fusion and reabsorption: agenesis (Types I and II), lack of fusion (Types III and IV), lack of reabsorption (Types V and VI), and lack of posterior development (Type VII).
34 It was later discovered that the increased renal expression of SGLT2 a high-capacity low-affinity transporter in patients with T2D is responsible for 80% to 90% of renal glucose reabsorption.
If this reabsorption does not take place, the body loses calcium.
However, AQP4 presence in the CSF has also been proposed as a diagnostic biomarker of hydrocephalus type [5]; additionally the sites and mechanisms of CSF reabsorption are relevant to the pathophysiology of hydrocephalus [6].

Canagliflozin is the first in a new class of medications known as selective sodium glucose cotransporter 2 (SGLT2) inhibitors; they act by blocking the reabsorption of glucose by the kidney, increasing glucose excretion, and lowering blood glucose levels in people with diabetes who have elevated blood glucose levels, the FDA said in a statement announcing the approval.
When chief cells in our parathyroid glands sense that calcium in our blood is too low, parathyroid hormone is released, resulting in an increase of serum calcium through multiple means: receptor-mediated tubular reabsorption of calcium in the kidney, release of skeletal calcium stores, upregulation of 1-a-hydroxylase leading to increased 1,25-d hyd roxy-yitamin D production, and increased calcium reabsorption from the gastrointestinal tract
