Background—Propionic acid derived from colonic bacterial fermentation contributes substantially to overall propionate load in children with disorders of propionate metabolism, and its reduction is important for adequate metabolic control. Aims—To evaluate the in vitro and in vivo eVects of antibiotic treatment on propionate production by colonic bacteria, and plasma propionate concentrations in...

Effects of amount of feed intake on in vivo remen propionate production and the reproducibility of measurements of propionate production rates were investigated in five dairy steers weighing 142 to 228 kg. Each steer received 275 g of an 80%-grain diet every 2 hours, and three of the five steers later received 500 g/2 hours. Rumen propionate pool sizes and production rates were determined at bo...

1. The assimilation of propionate by Polytomella caeca involves the beta-oxidation of this fatty acid. 2. Propionate-grown cells immediately oxidize propionate, beta-hydroxypropionate, malonic semialdehyde and acetate; acetate-grown cells oxidize propionate rapidly only after a lag of 2hr., and this adaptation of resting cells to propionate involves the formation of the enzymes of beta-oxidatio...

OBJECTIVE The colonic microbiota ferment dietary fibres, producing short chain fatty acids. Recent evidence suggests that the short chain fatty acid propionate may play an important role in appetite regulation. We hypothesised that colonic delivery of propionate would increase peptide YY (PYY) and glucagon like peptide-1 (GLP-1) secretion in humans, and reduce energy intake and weight gain in o...

the aim of the present study was to investigate the potential of nanoemulsion formulation for topical delivery of clobetasol propionate (cp) using algal oil (containing omega-3 fatty acids) as the oil phase. cp has anti-inflammatory, immunomodulatory and antiproliferative activities. however, its clinical use is restricted to some extent due to its poor permeability across the skin. algal oil w...

Salmeterol/fluticasone propionate, administered twice daily via a multidose dry powder inhaler (Seretide/Advair Diskus), Seretide Accuhaler or metered-dose hydrofluoroalkane (chlorofluorocarbon-free) inhaler (Seretide Evohaler), is a combination of the long-acting beta(2)-adrenoceptor agonist (beta(2)-agonist) [LABA] salmeterol and the corticosteroid fluticasone propionate. Maintenance therapy ...

The pathway of propionate conversion in a syntrophic coculture of Smithella propionica and Methanospirillum hungatei JF1 was investigated by (13)C-NMR spectroscopy. Cocultures produced acetate and butyrate from propionate. [3-(13)C]propionate was converted to [2-(13)C]acetate, with no [1-(13)C]acetate formed. Butyrate from [3-(13)C]propionate was labeled at the C2 and C4 positions in a ratio of...

The effects of acetate, propionate, and butyrate on the anaerobic thermophilic conversion of propionate by methanogenic sludge and by enriched propionate-oxidizing bacteria in syntrophy with Methanobacterium thermoautotrophicum delta H were studied. The methanogenic sludge was cultivated in an upflow anaerobic sludge bed (UASB) reactor fed with propionate (35 mM) as the sole substrate for a per...
