Abstract:
Hydrogen sulfide, H2S, is the third endogenous gas with cardiovascular properties (the others are nitric oxide and carbon monoxide). In fact, among other important signaling functions, H2S plays a key role in regulating blood pressure. Cystathionine ß-synthase, cystathionine γ-lyase (CSE) and 3-mercaptopyruvate sulfurtransferase are the principal enzymes devoted to H2S formation. We have recently shown that H2S levels are decreased in patients on chronic hemodialysis through the transcriptional deregulation of the CSE gene, hinting at the possibility that a link exists between this finding and hypertension and the high cardiovascular mortality typical of these patients.

Hemodialysis I: Introduction
Renal Regulation of Acid-Base Balance
In the kidneys, cells within the proximal convoluted tubules (PCT) and the collecting ducts secrete hydrogen ions (H+) into the tubular fluid. Specifically, in the PCT, Na+/H+ antiporters secrete H+ while reabsorbing Na+.
However, the intercalated cells in...

Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
