... about bimodal breathers, which utilize both water and air. Here, we characterized the influence of temperature on arterial acid–base balance and intracellular pH (pH i ) in the bimodal-breathing swamp eel, Monopterus albus . This teleost uses the buccopharyngeal cavity for gas exchange and has very...

... by a significant increase in inorganic phosphate levels from 0.3±0.3 to 9.5±3.4 mol g –1 , and a drop in intracellular pH from 7.48±0.03 to 6.81±0.05 in muscle. This coincides with the point when the fish change gait from subcarangiform swimming to kick-and-glide bursts. As the number of kicks increased, so too...

... in intracellular pH (pHi) that was dependent on Ca 2+ influx from the extracellular medium as well as Ca 2+ release from intracellular pools. Surprisingly, this increase in pHi and intracellular Ca 2+ concentration,[Ca 2+ ] i , was not accompanied by any change in proton secretion. By contrast, removal...

...Khaled H. Ahmed; Bernd Pelster; Gerhard Krumschnabel SUMMARY In trout hepatocytes, hypertonicity and cytosolic acidification are known to stimulate Na + /H + exchanger (NHE) activity, which contributes to recovery of cell volume and intracellular pH (pHi),respectively. The present study...

... increase in lumen pH to 6.32±0.04 ( N =5). Intracellular pH was 6.97±0.01 and 6.82±0.04 in unstimulated and serotonin-stimulated tubules, respectively. Lumen pH was altered whereas intracellular pH was tightly regulated during serotonin and bumetanide treatment. Furthermore, DIDS or amiloride treatment did...

..., and a recovery only limited by the physical stability of the utilized optical system. Intracellular pH (pH i ) in Danio rerio embryos between 1k-cells stage and the end of epiboly was found to be well regulated to a mean value of 7.55±0.13 (± s . d .), a range distinctly more alkaline than typical values...

... downregulation, characterized by a steep drop in intracellular pH (pH i ) and ATP levels. Using dot blots of total mitochondrial RNA, we show that during in organello incubations both O 2 deprivation and acidic pH (pH 6.4) elicit increases in half-lives of selected mitochondrial transcripts on the order of five...

...M. Furimsky; T. W. Moon; S. F. Perry ABSTRACT The mechanisms of intracellular pH (pHi) regulation were examined in hepatocytes of the rainbow trout Oncorhynchus mykiss . pHi was monitored using the pH-sensitive fluorescent dye BCECF, and the effects of various media and pharmacological agents were...
