For studying the effects of different levels of testosterone propionate on growth, survival and sex-ratio, five different doses such as 125, 100, 75, 50, 25 mg hormone per kg feed were administered to 5-day old Clarias gariepinus fry through diet for a period of 40 days. The growth performance in terms of weight and length gain of the fry receiving 100 and 75 mg hormone per kg feed were signifi...

Short chain fatty acids (SCFA), including acetate, propionate, and butyrate, are produced during bacterial fermentation of undigested carbohydrates in the human colon. In this study, we applied a stable-isotope dilution method to quantify the in vivo colonic production of SCFA in healthy humans after consumption of inulin. Twelve healthy subjects performed a test day during which a primed conti...

In its natural environment, Escherichia coli is exposed to short-chain fatty acids, such as acetic acid or propionic acid, which can be utilized as carbon sources but which inhibit growth at higher concentrations. DNA microarray experiments revealed expression changes during exponential growth on complex medium due to the presence of sodium acetate or sodium propionate at a neutral external pH....

1. Kidney-cortex slices and the perfused livers of vitamin B(12)-deficient rats removed propionate from the incubation and perfusion media at 33 and 17% respectively of the rates found with tissues from rats receiving either a normal or a vitamin B(12)-supplemented diet. There was a corresponding fall in the rates of glucose synthesis from propionate in both tissues. 2. The addition of hydroxoc...

Inhaled corticosteroids (ICSs) treatment combined with long-acting β2-adrenoceptor agonists (LABAs) reduces the risk of exacerbations in COPD, but the use of ICSs is associated with increased incidence of pneumonia. There are indications that this association is stronger for fluticasone propionate than for budesonide. We have examined systematic reviews assessing the risk of pneumonia associate...

BACKGROUND Foods with a low glycemic index are increasingly being acknowledged as beneficial for individuals with disorders related to the insulin resistance syndrome. The presence of certain salts of organic acids has been shown to lower the glycemic index of bread products and one of the suggested mechanisms is a lowered gastric emptying rate (GER). One obvious pitfall with many of the common...

Methyl propionate, also known as methyl propanoate, is a clear colourless liquid with a characteristic odour (fruity smell and taste). In this study, the formation of methyl propionate through the esterification of propionic acid and methanol was investigated in the reactive distillation system using a conventional (CBD), single feed (SF-SBD), and double feed semi-batch distillation (DF-SBD) co...

The contents of GABA, glutamine (Glu) and asparagine (Asp) acids as well as activities of glutamatdecarboxylase (GDK; CF 4.1.1.15) and 4-aminobutirat: 2-oxoglutarataminotransferase (GABA-T: CF 2.6.1.19) in brain cortex, cerebellum, brainstem and hypothalamus under impact of testosterone propionate at a dose of 5 mg/100 g of alive weight of adult albino male rats in spring and autumn were studie...

The effect of several fatty acid derivatives on methane and propionate in the rumen is described. A possible explanation for the observed inverse relationship between methane and propionate is given.
