... sequence of gluconate<acetate<chloride. This is in accordance with a model that ruminal and omasal transport of anions such as chloride and acetate has to occur via a transcellular route and involves channel-mediated basolateral efflux, driven by Na + /K + -ATPase. * Author for correspondence...

...Wade E. Bell; Robin R. Preston; Junji Yano; Judith L. Van Houten SUMMARY Paramecium tetraurelia is attracted to acetate and biotin by swimming smoothly and fast up gradients of these attractants, and turning immediately and slowing down when leaving these stimuli. We use a group of mutants, each...

Meynial-Denis ABSTRACT Acetate oxidation was examined by 13 C nuclear magnetic resonance in skeletal muscle from adult and old rats. Rats fasted for 5 days were perfused with [2- 13 C]acetate over 2 h, and muscle...

...I. D. Hume; W. H. Karasov; B. W. Darken ABSTRACT We have measured unidirectional uptake (not transmural flux) of acetate, butyrate and proline by everted sleeves of intact tissue from the jejunum, caecum, proximal colon and distal colon of prairie voles ( Microtus ochrogaster ). There was active...

...E. Titus; G. A. Ahearn ABSTRACT Purified basolateral membrane vesicles were prepared from the intestinal epithelium of the tilapia Oreochromis mossambicus , a herbivorous teleost. Characteristics of volatile fatty acid (VFA) transport were investigated using [ 3 H]acetate as a representative anion...

...Eric Titus; Gregory A. Ahearn ABSTRACT Short-chain fatty acid (SCFA) concentrations of intestinal contents from the herbivorous tilapia, Oreochromis mossambicus , were analysed by gas and high-performance liquid chromatography. Concentrations of acetate ranging from 3 to 18 mmol I −1 were found...
