Leaver (3) and Leaver and Wood (4) found with resting cells of Propionibacterium arabinotim that formaldehyde-Cl4 was incorporated into each position of propionic and succinic acids during fermentations of glucose, pyruvate, or glycerol. These findings raised the question of whether a total synthesis of the products from formaldehyde had occurred; that is, formation of molecules in which all ca...
We wanted to compare the efficacy and safety of fluticasone propionate, a new topically active inhaled corticosteroid, to that of high dose beclomethasone dipropionate, in severe adult asthma. Patients currently receiving between 1.5-2.0 mg.day-1 of an inhaled corticosteroid were treated for six weeks in a double-blind, randomized, parallel group study with 1 mg.day-1 fluticasone propionate (n ...
BACKGROUND Short-chain fatty acids (SCFAs), including acetate, propionate, and butyrate, are the main products of microbial fermentation in the gut and might mediate some of the effects of gut microbiota and nutrition on development, metabolism, and pathogenesis of obesity and other diseases. OBJECTIVE The objective of this study was to determine the effects of SCFAs on adipocyte differentiat...
Grain feeding often causes a decrease in ruminal pH, and experiments were conducted to define the role of pH in regulating the acetate to propionate ratio and production of CH4. Cows that were fed 90% concentrate had lower ruminal pH values (6.22 vs. 6.86), higher VFA concentrations (85 vs. 68 mM), and lower acetate to propionate ratios (2.24 vs. 4.12) than did cows that were fed forage only. W...
BACKGROUND Short-chain fatty acids (SCFA) produced through fermentation of nondigestible carbohydrates by the gut microbiota are associated with positive metabolic effects. However, well-controlled trials are limited in humans. AIMS To develop a methodology to deliver SCFA directly to the colon, and to optimise colonic propionate delivery in humans, to determine its role in appetite regulatio...
Fluticasone propionate is a fluoromethyl androstane 17beta-carbiothioate that is classified for dermatological use as a moderate potency corticosteroid. It is available in 0.05% cream and 0.005% ointment formulations for the treatment of patients with inflammatory dermatoses responsive to corticosteroids. Although it demonstrates greater activity than other corticosteroids of similar potency in...
Fluticasone propionate is a new corticosteroid with low systemic bioavailability. This study reports the outcome of a double blind clinical trial comparing oral fluticasone propionate (5 mg four times daily) with placebo for the treatment of active distal ulcerative colitis. Sixty patients were treated for four weeks, with assessments at two and four weeks. One patient was withdrawn when she wa...
A new propionate (prp) locus of S. typhimurium was defined by mutation, was located to minute 8 of the chromosome, and was shown to be transcribed in the clockwise direction. A plasmid carrying the wild-type prp+ locus was isolated by complementation and its initial physical characterization is presented. Transcriptional regulation of prp was studied using MudI1734(lacZ+) operon fusions. Propio...
Female Sprague-Dawley 5-day-old rats were given s.c. either 0.05 ml sesame oil, 1.25 mg progesterone, 0.1 mg estradici benzoate, or 1.25 mg testosterone propionate. At 55 days of age all rats were given 20 mg of 7,12-dimethylbenz(a)anthracene (DMBA) by stomach tube. All rats were killed at 190 days of age. Both the estradiol and the testosterone propionate treatments decreased the mammary adeno...
The influence of propionate supplementation on the splanchnic metabolism of amino acids (AA) and other N compounds (urea-N and NH3-N) and the supply of AA and NH3-N to the hindlimb was investigated in growing lambs. Six rumen-cannulated and multicatheterised lambs (32.2 kg) were fed frozen rye grass at 690 kJ metabolisable energy intake/d per kg average metabolic body weight. They were infused ...
