Phenylethylamine, a possible link to the antidepressant effects of exercise?

OBJECTIVES To determine in this pilot study whether aerobic exercise affects phenylacetic acid concentration in the urine. METHODS Twenty healthy men provided 24 hour urine samples on two consecutive days for the determination of phenylacetic acid levels. Before and during day 1, subjects refrained from physical activity; on day 2 subjects ran on a treadmill at 70% of their maximal heart rate...

Communication regarding metabonomic identification of two distinct phenotypes in Sprague-Dawley (Crl:CD(SD)) rats.

In a recent publication, we reported the identification and characterization of two distinct phenotypes in SpragueDawley rats obtained from the Charles River Raleigh facility (Robosky et al., 2005). The phenotypes were designated as HIP (high hippuric acid level in urine) and CA (high chlorogenic acid metabolites level in urine). The endogenous urinary metabolic profile of each phenotype was di...

The origin of urinary aromatic compounds excreted by ruminants. 1. The metabolism of quinic, cyclohexanecarboxylic and non-phenolic aromatic acids to benzoic acid.

1. The contribution of dietary constituents to the large urinary output of benzoic acid characteristic of ruminants and some herbivores is not well understood. 2. Methods for the analysis of quinic, cyclohexanecarboxylic, benzoic, phenylacetic, 3-phenylpropionic and cinnamic acids in urine and in rumen fluids were developed. 3. The urinary output of aromatic acids by sheep given seven-rations w...

I. S 24 perennial ryegrass was harvested at six stages of its growth from young leafy herbage to mature grass in which the seed had shed. 2. Two sheep were offered Ikg/d of each cut and two other sheep were offered 750 g/d of each cut of grass. 3. The contents of some possible precursors of the urinary aromatic acids excreted by sheep, namely, shikimic acid, quinic acid, chlorogenic acid, total...
