Evaluation of p-aminohippurate as a marker for blood-flow determinations in cattle [PDF]
, 1981 P-aminohippurate (PAH) was evaluated as a potential blood-flow marker in steers for use in trans-organ balance studies. Because of problems in methods available for PAH determination, a high pressure liquid chromatography (HPLC) procedure was developed ...

Chemical assay of p-aminohippuric acid simplified by use of dimethylaminocinnamaldehyde in ethanol.
Clinical Chemistry, 1988 Abstract We have developed a new and simple method of p-aminohippuric acid determination by use of dimethylaminocinnamaldehyde (DACA). It differs from previous methods using DACA in that the reaction is carried out in ethanol rather than in dilute acid. This results in deeper and more stable color development.

Journal of Dairy Science, 1986 Three experiments were conducted to evaluate effects of abomasal infusion of glucose or starch on absorption of metabolites (glucose, L-lactate, volatile fatty acids, and nitrogenous compounds) from portal-drained viscera of a nonlactating Holstein cow ...

Evaluation of the transporter-mediated herb-drug interaction potential of DA-9801, a standardized dioscorea extract for diabetic neuropathy, in human in vitro and rat in vivo [PDF]
, 2014 BACKGROUND: Drug transporters play important roles in the absorption, distribution, and elimination of drugs and thereby, modulate drug efficacy and toxicity. With a growing use of poly pharmacy, concurrent administration of herbal extracts that modulate

The Prolonging Action of Penicillin by Para-Aminohippuric Acid.
Experimental Biology and Medicine, 1945 Conclusions1. When the plasma para-aminohippuric acid concentration was maintained at or above 10 mg/100 ml a 3 to 6 fold elevation in penicillin plasma concentration was obtained except in two instances. 2. When the para-aminohippuric acid plasma levels were allowed to fall below 10 mg/100 ml there was no effect of that compound on the plasma ...

Analysis of urinary exosomal metabolites identifies cardiovascular risk signatures with added value to urine analysis [PDF]
, 2020 Background: Subclinical atherosclerosis may result in fatal cardiovascular (CV) events, but the underlying mechanisms and molecular players leading to disease are not entirely understood. Thus, novel approaches capable of identifying the factors involved

NMR in Biomedicine, Volume 38, Issue 8, August 2025.This study identified five attentional control subgroups in school‐aged children, with and without ADHD, using VR‐based behavioral tests. NMR metabolomics revealed subgroup‐specific urinary metabolic profiles linked to energy and amino acid metabolism.
