Diagnosis of tetrahydrobiopterin deficiency using filter paper blood spots: further development of the method and 5 years experience [PDF]
, 2018 In every newborn with even mild hyperphenylalaninemia (HPA) tetrahydrobiopterin (BH4) deficiencies need to be excluded as soon as possible. Differential diagnosis is most commonly performed by analysis of urinary neopterin and biopterin.

Rapid Communications in Mass Spectrometry, Volume 39, Issue 14, 30 July 2025.ABSTRACT Rationale Edaravone (EDA) is a radical scavenger and an antioxidant drug approved to treat amyotrophic lateral sclerosis and used as a research tool to explore treatment of neurodegenerative diseases and cancers. It is also a reactive agent, known as PMP (1‐phenyl‐3‐methyl‐5‐pyrazolone), used for the analysis of polysaccharides composition ...

Ultraviolet-induced fluorescent imaging for millipede taxonomy [PDF]
Research Ideas and Outcomes, 2017 Fluorescent imaging has been traditionally applied to cell biology, and more recently to entomology to capture microscopic images of insect anatomy. However, the technique has not been applied to the study of millipedes, most of which autofluoresce as a ...

The compositional and evolutionary logic of metabolism
, 2012 Metabolism displays striking and robust regularities in the forms of modularity and hierarchy, whose composition may be compactly described. This renders metabolic architecture comprehensible as a system, and suggests the order in which layers of that ...

Mechanism of photooxidation of folic acid sensitized by unconjugated pterins [PDF]
, 2010 Folic acid, or pteroyl-L-glutamic acid (PteGlu), is a precursor of coenzymes involved in the metabolism of nucleotides and amino acids. PteGlu is composed of three moieties: a 6-methylpterin (Mep) residue, a p-aminobenzoic acid (PABA) residue, and a ...
