Propionate is an important intermediate product during the methane fermentation of organic matter, and its degradation is crucial for maintaining the performance of an anaerobic digester. In order to understand the effect of temperature on propionate degradation, an upflow anaerobic sludge blanket (UASB) reactor with synthetic wastewater containing propionate as a sole carbon source was introdu...

This study reports new mesomorphic benzylethylammonium salts containing a 2,3,6,7,10-pentakis(dodecyloxy)-11-(hexyloxy)triphenylene unit and Cl - or [MCl 4 ] 2- (M = Cu, Ni, Co, Mn) as counterion. They show rich columnar polymesomorphism, characterized...

polyhydroxyalkanoates (phas) is known to be temporarily stored by microorganisms in activated sludge, especially in the anaerobic-aerobic processes. the main objective of this study was to investigate the effects of fatty acids (vfas) compounds coexistence in substrate of sbr on phas productivity of activated sludge. it has been found that addition of different concentrations of vfas results in...

Propionate is a quantitatively important methanogenic intermediate in anaerobic digesters and only limited number of microbes can utilize it under syntrophic association with methanogens. The propionate oxidizing bacterias are known to be slow growers due the low energy yield. Thus, get accumulated frequently negatively affect digester performance. In this study, degrading consortia from four d...

OBJECTIVE To explore the efficacy and safety of fluticasone propionate, cream and ointment, applied twice weekly in addition to maintenance treatment with emollients, in reducing the risk of relapse of chronic recurrent atopic dermatitis. DESIGN Randomised, double blind, parallel group study of 20 weeks' duration. SETTING Dermatology outpatient clinics (6 countries, 39 centres). PARTICIPA...

BACKGROUND Corticosteroids are widely used in the treatment of many inflammatory conditions but the exact mode of action on neutrophil function is uncertain. Fluticasone propionate is a new topically active synthetic steroid which can be measured in body fluids and which undergoes first pass metabolism. METHODS The effects of fluticasone propionate on the function of neutrophils isolated from...

Propionate-forming bacteria seem to be abundant in anoxic rice paddy soil, but biogeochemical investigations show that propionate is not a correspondingly important intermediate in carbon flux in this system. Mixed cultures of Opitutus terrae strain PB90-1, a representative propionate-producing bacterium from rice paddy soil, and the hydrogenotrophic Methanospirillum hungatei strain SK maintain...

The syntrophically propionate-oxidizing bacterium Syntrophobacter wolinii was grown in binary methanogenic coculture with Methanospirillum hungatei as sole partner, free of contaminating Desulfovibrio vulgaris. Substrate tests revealed that S. wolinii could grow also without any syntrophic partner, either with pyruvate as sole substrate or with propionate plus sulfate. Pyruvate was fermented to...

Clobetasol propionate is a super-high potent class 1 topical corticosteroid available in several formulations, including a spray formulation that is approved for use up to 4 weeks in patients aged 18 years and older with moderate to severe plaque psoriasis. The efficacy and safety of clobetasol propionate spray 0.05% has been extensively evaluated in clinical trials in more than 2200 patients w...
