The NaHCO3 cotransporter gene (SLC4A5) on chromosome 2 encodes a protein that transports sodium and bicarbonate across the cell membrane and regulates cellular pH. The National Heart, Lung, and Blood Institute Family Blood Pressure Program found linkage of blood pressure-related traits to the chromosomal region containing SLC4A5 and phenotype associations with single nucleotide polymorphisms (S...

Patterns of salivary HCO3 secretion vary and depend on species and gland type. However, the identities of the transporters involved in HCO3 transport and the underlying mechanism of intracellular pH (pHi) regulation in the salivary glands still remain unclear. In this experiment, we examined the expression of the Na/HCO3 cotransporter(NBC) and its role in pHi regulation in guinea pig salivary g...

We examined molecular and electrophysiological properties of the electroneutral sodium/bicarbonate cotransporter (NBCn1) that is present in rat hippocampal neurons. By PCR, a deletion variant (NBCn1-E) that lacks 123 amino acids in the cytoplasmic N-terminal domain was found in adult neurons. The previously characterized NBCn1-B, which does not have the deletion, was detected in embryonic neuro...

Introduction From the point of view of different technological processes, the knowledge of parameters describing the structure of sorbents, such as surface area or pore size distribution play an important role for application them in chemical, cement industries, or modification of mineral raw materials. The sorption properties are determined by surface area, what binds with surface energy and r...

This report aims to look at the role of Sodium bicarbonate as a potent Ergogenic aid and its role in improving the performance of athletes. It includes the mechanism of action of sodium bicarbonate during high-intensity exercise. The report also shows the various types of athletes who can be benefited from sodium bicarbonate loading, evidences for improvement in performance, conflicting evidenc...

OBJECTIVE This study evaluates the effect of early administration of an empirical (1 mEq/kg) sodium bicarbonate dose on survival from prehospital cardiac arrest within brief (<5 minutes), moderate (5-15 minutes), and prolonged (>15 minutes) down time. METHODS Prospective randomized, double-blinded clinical intervention trial that enrolled 874 prehospital cardiopulmonary arrest patients manage...

To evaluate the effectiveness of sodium bicarbonate (SB) in removing uranium and protecting animals from uranium toxicity, we intramuscularly administered 1 mg/kg of uranyl nitrate to 8-wk-old male SD rats, and 20 min after administration of uranyl nitrate, the animals were given a single oral administration of SB at 0.1, 0.3 or 1 g/kg. The SB treatment at a dose of 0.3 g/kg or more raised the ...

BACKGROUND AND PURPOSE This study was designed to compare the effects of high-intensity interval training (HIT) and moderate-intensity aerobic training (MOD) on functional recovery and cerebral plasticity during the first 2 weeks after cerebral ischemia. METHODS Rats were randomized as follows: control (n=15), SHAM (n=9), middle cerebral artery occlusion (n=13), middle cerebral artery occlusi...

INTRODUCTION Contrast-induced nephropathy is a common complication of radiographic procedures. Different measures have been used to avoid this damage, but the evidence is controversial. New investigations are required to clarify it. We investigated the efficacy and safety of sodium bicarbonate solution compared with sodium chloride solution to prevent contrast induced nephropathy in patients wi...

Mitochondria represent major sources of basal reactive oxygen species (ROS) production of the cardiomyocyte. The role of ROS as signaling molecules that mediate different intracellular pathways has gained increasing interest among physiologists in the last years. In our lab, we have been studying the participation of mitochondrial ROS in the intracellular pathways triggered by the renin-angiote...
