1. Bicarbonate increased citrate and 2-oxoglutarate accumulation when rat kidney cortex mitochondria were incubated with pyruvate or L(-)-palmitoyl carnitine in the presence of L-malate. 2. Bicarbonate stimulated the exit of citrate from mitochondria. The Km for bicarbonate was 13.5 mM and the Vmax was 0.59 nmol/min/mg of protein at 10 degrees. 3. The bicarbonate-stimulated exit of citrate from...

Sodium-bicarbonate cotransporters are homologous membrane proteins mediating the electrogenic or electroneutral transport of sodium and bicarbonate. Of the functionally characterized sodium-bicarbonate cotransporters (NBC), NBC1 proteins are known to be electrogenic. Here we report the cloning and functional characterization of NBC4c, a new splice variant of the NBC4 gene. At the amino acid lev...

The role of peripheral vascular tone in the development of hypotension induced by dialysis was investigated in eight patients undergoing haemodialysis with acetate or bicarbonate buffered fluid. Each patient had two sessions of dialysis with acetate fluid and two with bicarbonate fluid in the order acetate, bicarbonate, bicarbonate, acetate or bicarbonate, acetate, acetate, bicarbonate. Mean ar...

abstract background: sodium bicarbonate serum therapy is used for compensation bicarbonate lost and increasing blood ph in metabolic acidosis caused by severe anemia in patient with glucose-6-phosphate dehydrogenase (g6pd) deficiency. the aim of present study was comparison the effect of serum therapy using two different serums (serum with bicarbonate and without bicarbonate) on some renal and ...

Metabolic acidosis correction is one of the goals of renal replacement therapy. Correction of acidosis in peritoneal dialysis (PD) may be affected by PD modalities such as automated PD (APD) or by new solutions containing a combination of bicarbonate and lactate as a buffer [bicarbonate continuous ambulatory PD (CAPD)]. The aim of the present study was to examine the acid-base status of our PD ...

PURPOSE The aim of this study was to determine the effect and reliability of acute and chronic sodium bicarbonate ingestion for 2000-m rowing ergometer performance (watts) and blood bicarbonate concentration [HCO3-]. METHODS In a crossover study, 7 well-trained rowers performed paired 2000-m rowing ergometer trials under 3 double-blinded conditions: (1) 0.3 grams per kilogram of body mass (g/...

PURPOSE To examine the effect of beta-alanine only and beta-alanine with sodium bicarbonate supplementation on 2,000-m rowing performance. METHODS Twenty well-trained rowers (age 23 ± 4 y; height 1.85 ± 0.08 m; body mass 82.5 ± 8.9 kg) were assigned to either a placebo or beta-alanine (6.4 g · d(-1) for 4 weeks) group. A 2,000-m rowing time trial (TT) was performed before supplementation (Bas...

Spermatozoa undergo a poorly understood activation process induced by bicarbonate and mediated by cyclic adenosine 3',5'-monophosphate (cAMP). It has been assumed that bicarbonate mediates its effects through changes in intracellular pH or membrane potential; however, we demonstrate here that bicarbonate directly stimulates mammalian soluble adenylyl cyclase (sAC) activity in vivo and in vitro ...

among the healthy compounds such as sodium bicarbonate, potassium bicarbonate, vegetable oils, and biocontrol yeasts including heat treatments, as well as a good alternativeto chemical pesticides are considered hazardous. in this study, the effect of different levels of sodium bicarbonate treatment (0, 500 and 1000 mg/l and combination 1500 mg/l sodium bicarbonate with hot water 53 °c) were inv...
