Plasma 5-hydroxyindoleacetic acid as an endogenous index of renal plasma flow [PDF]
, 1989 Plasma 5-hydroxyindoleacetic acid as an endogenous index of renal plasma flow. 5-Hydroxyindoleacetic acid (5-HIAA), the major serotonin metabolite, was measured in human plasma and urine using liquid chromatography and electrochemical detection.

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 ...

The effects of carboxylic acids on the aqueous dispersion and electrophoretic deposition of ZrO2 [PDF]
Journal of the European Ceramic Society, Volume 32, Issue 1, 2012,
Pages 235-244, 2013 The agglomeration, electrokinetic properties and electrophoretic deposition behaviour of aqueous suspensions of ZrO2 with carboxylic acid additives were studied in comparison with conventional pH adjustment. It was found that citric acid imparted negative zeta-potential values and electrosteric stabilisation to particles in suspensions at all pH levels.

Learning the Hydrophilic, Hydrophobic and Aromatic Character of Amino Acids from their Interfacial Thermal Conductance in Water [PDF]
, 2021 In this study, the thermal relaxation of the 20 naturally occurring amino-acids in water is investigated using transient non-equilibrium molecular-dynamics simulations. By modeling the thermal relaxation process, the relaxation times of the amino-acids in water occurs over a timescale covering 2-5 ps.

Nature's Starships. I. Observed Abundances and Relative Frequencies of Amino Acids in Meteorites [PDF]
, 2014 The class of meteorites called carbonaceous chondrites are examples of material from the solar system which have been relatively unchanged from the time of their initial formation. These meteorites have been classified according to the temperatures and physical conditions of their parent planetesimals.

Journal of Food Science, Volume 89, Issue 12, Page 10134-10151, December 2024.Abstract Olive oil polyphenol hydroxytyrosol (HT) significantly repairs intestinal barrier function, but its absorption in the stomach and small intestine is limited. The metabolites of unabsorbed HT that reach the colon are crucial, yet their effects on colonic microbiota and intestinal barrier repair remain unclear.

Meteoritic Abundances of Fatty Acids and Potential Reaction Pathways in Planetesimals [PDF]
Icarus, 2019, 319, 685-700, 2018 The origin of fatty acids on the prebiotic Earth is important as they likely formed the encapsulating membranes of the first protocells. Carbon-rich meteorites (i.e., carbonaceous chondrites) such as Murchison and Tagish Lake are well known to contain these molecules, and their delivery to the early planet by intense early meteorite bombardments ...
