choline acetyltransferase/stroke

OBJECTIVE Alterations in cholinergic activity have not been systematically studied in types of cerebrovascular disease. We examined cholinergic function at postmortem, focussing on stroke and vascular dementia (VaD). METHODS Post-mortem brain tissue was studied from 61 patients with stroke or VaD

The cellular mechanisms underlying the neuroprotective action of the immunosuppressant FK506 in experimental stroke remain uncertain, although in vitro studies have implicated an antiexcitotoxic action involving nitric oxide and calcineurin. The present in vivo study demonstrates that

Choline acetyltransferase and acetylcholinesterase have been assessed in human aging brains, in demented and agonal states. Choline acetyl transferase decreased during aging in normal brain when measured in the cerebral cortex. Choline acetyltransferase was also reduced in several other brain areas

Background: Post-stroke cognitive impairment (PSCI) is commonest clinical disorder in which peripheral cholinergic activity is important. Oleuropein (OLP) is polyphenol is present in olive oil. Here we evaluated the effect of OLP in

Sporadic Alzheimer's disease (AD) accounts for a high proportion of AD cases. Therefore, it is of importance to investigate other factors that contribute to the etiology and progression of AD. AD is characterized by decreased cholinergic tone, tau hyperphosphorylation and beta-amyloid (Aβ)

Choline acetyltransferase (ChAT), the enzyme responsible for the formation of ACh from choline and acetyl-coenzyme A, is a marker of cholinergic function and is significantly depressed in the brains of Alzheimer patients. It has been shown that omental tissue contains several neuroactive substances

To study the role of central cholinergic mechanisms in hypertension, we have determined muscarinic receptors using [3H] (-)quinuclidinyl benzilate (QNB) and choline acetyltransferase (ChAT) activity in the brain regions of spontaneously hypertensive rats (SHR), stroke-prone SHR (SHRSP) and renal

A 53-year-old Japanese woman with a point mutation in mitochondrial DNA (tRNALeu(UUR), nt3243) consistent with mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS) and Alzheimer-type brain pathology is reported. This woman had suffered myopathy and psychosis

Post-stroke dementia (PSD) is a common clinical disease and the central cholinergic circuits are important to cognitive function. Icariin (ICA), a flavonoid isolated from Herba Epimedii, was reported to improve cognitive function through modulating the cholinergic system. But there were no studies

The demand for using parasympathetic activation for stroke therapy is unmet. In the current study, we investigated whether the neuroprotection provided by electroacupuncture (EA) in an experimental stroke model was associated with activation of the parasympathetic nervous system (PNS). The results

Stroke is one of the most-devastating brain diseases causing acute death or permanent disability. Although tissue-type plasminogen activator was approved by Food and Drug Administration for early reperfusion of the occluded vessels, oxidative injury may cause extensive brain infarction. Accordingly,

Senile dementia of the Alzheimer type is becoming one of the most common of the malignant diseases as our society ages. Currently, research has identified several pathophysiological changes, including the bihelical filament and the loss of the enzyme choline acetyltransferase from the cortex.

Diabetes mellitus, a metabolic disorder, is associated with neurological complications such as depression, anxiety, hypolocomotion, cognitive dysfunction, phobias, anorexia, stroke, pain, etc. Traditional system of medicine is long known for its efficient management of diabetes. The current review

The aim of the study was to further investigate the effects of aniracetam, a cognition enhancer, and its metabolites on the brain cholinergic system. We measured choline acetyltransferase activity and acetylcholine release using in vivo brain microdialysis in stroke-prone spontaneously hypertensive
