33.4. Low pH and high [HCO3] stimulate ion transport across isolated gills of the crab Chasmagnathus granulatus via different cellular mechanismsThe LvCHH-ITP gene of Litopenaeus vannamei consists of 4 exons and 3 introns spanning 3.8 kb in size. The primary gene transcript produced a cDNA ...
Briefly, samples of plasma, PEG-Hboxy solutions and PEG-Hbdeoxy solutions at various dilutions in a 10 mM phosphate buffer, pH 7.4 were added of 10 mM NAD+ (lithium salt) and 10 mM L-lactate. NADH formation was monitored at 340 nm using a Cary 4000 UV–VIS ...
Besides, the temperature of geothermal water depends on such factors as the proportion of cold surface water, the depth of geothermal water and availability of favorable geological condition. Figure 7. Diagrams of δ18O value versus TDS, Sr, HCO3-, SO42-, SiO2 and Br of geothermal water in...
This accumulation mechanism operates at external pH values of 4 and less. Under these conditions CO2 must be the carbon species crossing the plasmlemma, and since preliminary evidence suggests that the transport mechanism is active primary uniport of HCO3–, it is proposed that the site of the ...
A soil-zone Ca-HCO3- water from glacial till was reacted, using a reaction-modelling program, with three different suites of minerals: a kimberlite suite, a felsic intrusive suite and a mafic intrusive suite. Decreasing pH and alkalinity with increasing water/rock ratios in model reactions with...
We have now investigated the transport mechanism which leads to pHi changes in the nominal absence of CO2/HCO3−, where the HCO3− concentration is expected to be below 1 mm. 2 The intracellular pH increased and then decreased when pHo was altered from 7.4 to 7.8 and then 7.0 with a ...
This re-swelling phase was inhibited by the external DIDS, acetozolamide and bicarbonate, and was slightly dependent upon pH ranging from 5 to 7.2. The analysis shows that chloride-induced re-swelling cannot be directly explained by the reversion of OH or HCO3 gradients which drive the Cl ...
29、d.2, chronic respiratory acidosis may be compensatory due to the compensatory effect of the kidney.Metabolic alkalosisMetabolic alkalosis (metabolic alkalosis) is a type of acid-base imbalance in extracellular liquid increase or loss of H+ caused by the increase of plasma HCO3- and pH were ...
The substituted carboxylic and benzoic acids are take an anionic form in the basic pH of natural groundwater and, as a result, are highly soluble in water. Initial laboratory tests showed conservative behavior for these compounds (150 °C, 172 h, in nitrogen and oxygen atmospheres) (Adams et...
Meanwhile, LE diets disrupted the structural integrity of the piglets' intestines and decreased jejunal tight junction protein (occludin and claudin-1) expression (P < 0.05). Additionally, the pH and HCO3− in the arterial blood of piglets in the LE group were lower than those in the ME ...
