Platelet-mediated metabolism of the common dietary flavonoid, quercetin. [PDF]
Flavonoid metabolites remain in blood for periods of time potentially long enough to allow interactions with cellular components of this tissue. It is well-established that flavonoids are metabolised within the intestine and liver into methylated ...

Prediction of schizophrenia using MAOA-uVNTR polymorphism: A case–control study
Context: Schizophrenia has been associated with disorder of the dopamine system, which is downregulated by projections of the serotonin pathway. Dopamine and serotonin levels are regulated by a system of transporters and enzymes.

In Vivo Biosynthesis and Direct Incorporation of Noncanonical Amino Acids into Proteins. [PDF]
This review evaluates engineered (semi)autonomous cell systems for the biosynthesis and incorporation of noncanonical amino acids (ncAAs) into proteins. While semi‐autonomous cells convert supplied precursors into ncAAs autonomous cells integrate biosynthetic pathways that produce these building blocks intracellularly.

Loss of physical contact in space alters the dopamine system in C. elegans
Summary: Progressive neuromuscular decline in microgravity is a prominent health concern preventing interplanetary human habitation. We establish functional dopamine-mediated impairments as a consistent feature across multiple spaceflight exposures and ...

Consensus Guideline for the Diagnosis and Treatment of Tyrosine Hydroxylase (TH) Deficiency. [PDF]
ABSTRACT Tyrosine hydroxylase (TH) catalyses the rate‐limiting step in dopamine biosynthesis. Autosomal recessive tyrosine hydroxylase deficiency (THD) leads to clinical phenotypes reflecting the deficiency of dopamine, norepinephrine, or epinephrine in the central nervous system (CNS), presenting along a continuous spectrum from mild to severe forms ...

Dopamine System Dysfunction in Alzheimer's Disease. [PDF]
ABSTRACT The dopaminergic system may be at the base of some neurobehavioral symptoms, as apathy and depression, and extrapyramidal symptoms, often seen in Alzheimer's disease patients. It can also have an impact on cognitive decline, as extrapyramidal symptoms, classically linked with dopamine dysfunction, are associated with increased risk of ...
