TLDR
Describing seemingly trivial variations in the preparation of blood plasma for amino acid analysis, and in the operation of the automatic amino acid analyzer, that can lead to major errors in the quantitative determination of taurine, phosphoethanolamine, the dicarboxylic amino acids, glutamine, and the disulphide amino acids is described.About:

The pathogenesis of coronary artery disease. A possible role for methionine metabolism.
D E Wilcken,B Wilcken +1 more
TL;DR: A reduced ability to metabolise homocysteine in some patients with premature coronary artery disease when this pathway is stressed is suggested.

Almost all about citrulline in mammals.

TL;DR: One of the most promising research directions deals with the administration of citrulline as a more efficient alternative to arginine, especially against underlying splanchnic sequestration of amino acids.

Retinal degeneration associated with taurine deficiency in the cat.
TL;DR: A sulfur amino acid deficit in the casein diet combined with specific amino acid requirements of the cat appear related to this unique expression of taurine deficiency in cats.
Journal ArticleDOI
Homocysteinemia due to folate deficiency
TL;DR: Observations support the hypothesis that depletion of tissue folate causes homocysteinemia in nonhomocystinuric subjects and relatively normal levels of serum total homocyst(e)ine were observed in four pregnant women with low serum folate, supporting previous suggestions of an influence of female sex hormone(s) in homocysteine metabolism.
Journal ArticleDOI
Folic acid--an innocuous means to reduce plasma homocysteine
TL;DR: It is proposed that folic acid in excess acts by enhancing the remethylation of homocysteine to methionine, which confirms a previous report and might be of use as prophylaxis.

TL;DR: It has been possible to identify with a high degree of probability twenty-eight ninhydrin-positive substances in protein-free plasma and to determine most of them quantitatively.

Ion exchange chromatography of the free amino acids in the plasma of the newborn infant.
TL;DR: It was concluded that heel puncture plasma would be satisfactory for routine clinical purposes and a number of small peaks which have not been noted previously in plasma have been indicated on the chromatogram.
