Bilateral deep brain stimulation (DBS) of globus pallidus internus (GPi) for the treatment of benign hereditary chorea and other childhood onset choreas: a single-center experience.

Purpose: Chorea is a clinical sign characterized by involuntary, rapid, unpredictable, and irregular muscle movements that can affect various parts of the body. It can be seen in various medical conditions, both neurological and systemic, of genetic and acquired etiology. Deep brain stimulation (DBS) of the globus pallidus internus (GPi) has been used to treat various types of chorea.

Adaptations in glutathione-based redox protein signaling pathways and alcohol drinking across species.

Alcohol use disorder (AUD) is the most prevalent substance use disorder but there is incomplete knowledge of the underlying molecular etiology. Here, we examined the cytosolic proteome from the nucleus accumbens core (NAcC) of ethanol drinking rhesus macaques to identify ethanol-sensitive signaling proteins. The targets were subsequently investigated using bioinformatics, genetic, and pharmacological manipulations in mouse models of ethanol drinking.

Transgenic expression of human cytochrome P450 2E1 in C. elegans and rat PC-12 cells sensitizes to ethanol-induced locomotor and mitochondrial effects.

Chronic alcohol (ethanol) use is increasing in the United States and has been linked to numerous health issues in multiple organ systems including neurological dysfunction and diseases. Ethanol toxicity is mainly driven by the metabolite acetaldehyde, which is generated through three pathways: alcohol dehydrogenase (ADH2), catalase (CAT), and cytochrome P450 2E1 (CYP2E1). ADH2, while the main ethanol clearance pathway in the liver, is not expressed in the mammalian brain, resulting in CAT and CYP2E1 driving local metabolism of ethanol in the central nervous system.
