ubiquinone/stroke

A thirty-two-year-old woman who had been diagnosed MELAS with 3243A > G mutation presented headache, nausea, decreased bilateral visual acuity, and topographical disturbance on January 1 in 2002. Although brain CT showed no fresh lesion, recurrence of stroke-like episode was considered. Immediately,

The purpose of the current study was to investigate aspects of improved bioenergetic function using nicotinamide during stroke. Using a global ischemia-reperfusion mouse model, ATP was depleted by 50% in the brain. The use of nicotinamide to provide a large reserve of brain NAD+ restored ATP levels

BACKGROUND The genetic basis of stroke susceptibility remains to be elucidated. STR1 quantitative trait locus (STR1/QTL) was identified on rat chromosome 1 of stroke-prone spontaneously hypertensive rat (SHRSP) upon Japanese-style stroke-permissive diet (JD), and it contributes to 20% of the stroke

The neuroprotective effect of ubiquinone (coenzyme Q10)was demonstrated on the rats model of ischemic stroke provoked by persistent 24-h occlusion of the middle cerebral artery. Coenzyme Q10 (30 mg/kg) was injected intravenously in 60 min after artery occlusion. Ubiquinone crossed the blood-brain

A 29-year-old man with mitochondrial encephalomyopathy caused by partial deficiency of mitochondrial NADH-ubiquinone oxidoreductase (Complex I) is described. Clinical manifestations were characterized by generalized convulsion, dementia and stroke-like episodes consisting of hemianopsia, Gerstmann's

Defects in complex I due to mutations in mitochondrial DNA are associated with clinical features ranging from single organ manifestation like Leber hereditary optic neuropathy (LHON) to multiorgan disorders like mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS)

Eight carriers of the A3243G mutation of mitochondrial DNA without stroke-like episodes were monitored for up to 7 years in clinical and metabolic studies, by magnetic resonance imaging (MRI) and positron emission tomography (PET). None developed mitochondrial encephalopathy (MELAS), but 2 developed

BACKGROUND The isoprenoid pathway was assessed and compared in patients of lone atrial fibrillation with embolic stroke as well as in patients with right hemispheric, left hemispheric and bihemispheric dominance to determine the role of hemispheric dominance in its pathogenesis. RESULTS The

The objective of this study was to investigate a possible role of mitochondrial dihydrolipoamide dehydrogenase (DLDH) as a chemical preconditioning target for neuroprotection against ischemic injury. We used 5-methoxyindole-2-carboxylic acid (MICA), a reportedly reversible DLDH inhibitor, as the

Ndufc2, a subunit of the NADH: ubiquinone oxidoreductase, plays a key role in the assembly and activity of complex I within the mitochondrial OXPHOS chain. Its deficiency has been shown to be involved in diabetes, cancer and stroke. To improve our knowledge on the mechanisms underlying the increased

OBJECTIVE Coenzyme Q10 (CoQ10, ubiquinone) stands among the safest supplements in the elderly to protect against cardiovascular disorders. Noteworthy, CoQ10 deficiency is common in many surviving stroke patients as they are mostly prescribed statins for the secondary prevention of stroke incidence

Identifying changes in serum metabolites during cerebral ischemia is an important approach for early diagnosis of thrombotic stroke. Herein, we highlight novel biomarkers for early diagnosis of patients at high risk of thrombotic stroke using high resolution metabolomics (HRM). In this retrospective

A T-to-C transition mutation at nucleotide position 3,250 in the mitochondrial tRNA(Leu)(UUR) gene was present in a family with mitochondrial myopathy. Two of three muscle biopsies examined had complex I (NADH-ubiquinone oxidoreductase) deficiency. Heteroplasmy of wild and mutant mitochondrial DNA

BACKGROUND Statins inhibit the production of 2,3-dimethoxy,5-methyl,6-polyisoprene parabenzoquinone also known as ubiquinone or coenzyme Q10 (CoQ10), which is required for mitochondrial electron transport. Idiopathic or primary CoQ10 deficiencies have been known to cause mitochondrial
