Dopaminergic system genes in childhood aggression: possible role for DRD2.

Unlabelled: Excessive or deficient levels of extracellular dopamine have been hypothesized to contribute to a broad spectrum of mood, motor, and thought abnormalities, and dopaminergic system genes have been implicated in aggressive behaviour from animal and human studies. OBJECTIVE. We examined selected members of the dopaminergic system genes for association with child aggression.

Atomic absorption spectroscopy in ion channel screening.

This article examines the utility of atomic absorption spectroscopy, in conjunction with cold flux assays, to ion channel screening. The multiplicity of ion channels that can be interrogated using cold flux assays and atomic absorption spectroscopy is summarized. The importance of atomic absorption spectroscopy as a screening tool is further elaborated upon by providing examples of the relevance of ion channels to various physiological processes and targeted diseases.

Flux assays in high throughput screening of ion channels in drug discovery.

Ion channels have been identified as therapeutic targets in various disorders, such as cardiovascular disease, neurological disease, and cystic fibrosis. Flux assays to detect functional ionic flux through ion channels are becoming increasingly popular as tools for screening compounds. In an optimized flux assay, modulation of ion channel activity may produce readily detectable changes in radiolabeled or nonradiolabeled ionic flux.
