Molecular Ecology, EarlyView.Abstract Colour signals play pivotal roles in different communication systems, and the evolution of these characters has been associated with behavioural ecology, integumentary production processes and perceptual mechanisms of the species involved. Here, we present the first insight into the molecular and histological basis of skin colour polymorphism ...

Frontiers in Microbiology, 2016 Tetrahydrofolate (THF) and its one-carbon derivatives, collectively termed folates, are essential cofact¬ors, but are inherently unstable. While it is clear that chemical oxidation can cleave folates or damage their pterin precursors, very little is ...

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 ...

Studies on the Degradation of Pterine and Pterine-6-carboxylic Acid by Pseudomonas fluorescens UK-1. [PDF]
Acta Chemica Scandinavica, 1975 Pseudomonas fluorescens UK-1 has been incubated in basal mineral medium which was 0.5mM in pterine or pterine-6-carboxylic acid. During incubation the test organism splits the pteridine ring by liberating carbon dioxide from position 2. Glucose added to the medium greatly enhances both the growth of the organism and the carbon dioxide formation ...

Movement Disorders, Volume 40, Issue 5, Page 938-949, May 2025.Abstract Background Patients with mutations in the monocarboxylate transporter 8 (MCT8, SLC16A2) suffer from X‐linked recessive Allan‐Herndon‐Dudley syndrome (AHDS), which is characterized by developmental delay and a severe movement disorder. Current trials using thyroid hormone derivatives to overcome the transporter defect have failed to achieve ...
