ubiquinone/infarction

A total of 620 patients with acute myocardial infarction were followed up in order to assess the efficacy of antihypoxants as a component of intensive care. 385 of these patients, divided into groups of 20-40 subjects, were administered one of 12 antihypoxants or sessions of hyperbaric oxygenation

Vitamin E and coenzyme Q10 (CoQ10) have antioxidant effects that may benefit cardiovascular health. Meta-analyses of randomized controlled trials have not shown a protective effect of supplementation with the vitamin E isomer α-tocopherol on the risk of acute myocardial infarction (AMI), but data on

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,

A significant consequence of ischemia/reperfusion (I/R) is mitochondrial respiratory dysfunction, leading to energetic deficits and cellular toxicity from reactive oxygen species (ROS). Mammalian complex I, a NADH-quinone oxidoreductase enzyme, is a multiple subunit enzyme that oxidizes NADH and

The effect of chronic coronary artery occlusion on the content of rat myocardial coenzymes Q (CoQ) and evaluation of the applicability of CoQ(10) for limiting postinfarct remodeling have been investigated. Left ventricle myocardium hypertrophy was characterized by the decrease in CoQ(9) (-45%, p <

Ubiquinone and ubiquinol represent the oxidized and reduced forms of Coenzyme Q10 (CoQ10). CoQ10 is present in membranes of almost all human tissues and organs, with highest concentration in the heart. In patients with heart failure, serum levels of the N-terminal pro-brain natriuretic peptide

Coenzyme Q10 (CoQ10 ) exists in a reduced (ubiquinol) and an oxidized (ubiquinone) form in all human tissues and functions, amongst others, in the respiratory chain, redox-cycles, and gene expression. As the status of CoQ10 is an important risk factor for several diseases, here we determined the

One hundred and sixty four (164) patients were evaluated. Sixty (60) with Sickle cell disease (SSHg.) and ninety seven (97) with Trait (ASHg.); seventeen (17) were normal control group. The study confirmed that the incidence of cardiomyopathy in Trait (ASHg.) is greater than reported by other

Previous studies suggested that certain lipid-lowering drugs such as statins suppress ubiquinone, affect mitochondrial function, and may have deleterious effect on skeletal or cardiac muscles with potentially serious clinical consequences, especially in patients with established coronary heart

According to modern images and results of our observations the oxidative stress (OS) is a non-specific though certain component of pathogenesis at numerous diseased states of organism having in the basis the thoroughness of pathogenic disturbances of phospholipids (PL) metabolism and processes of

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

In this study we examined the effect of inhibition of MMP-2 expression, using siRNA, on the cardiomyocyte proteome. Isolated cardiomyocytes were transfected with MMP-2 siRNA and incubated for 24h. Control cardiomyocytes from the same heart were transfected with scrambled siRNA following the same

BACKGROUND Reactive oxygen species (ROS) mediate the effects of anesthetic precondition to protect against ischemia and reperfusion injury, but the mechanisms of ROS generation remain unclear. In this study, the authors investigated if mitochondria-targeted antioxidant (mitotempol) abolishes the

Sirtuin1 (Sirt1) and Sirtuin3 (Sirt3) are known to participate in regulating mitochondrial function. However, whether Total Salvianolic Acid Injection (TSI) protects against myocardial ischemia/reperfusion (I/R) injury through regulating Sirt1, Sirt3, and mitochondrial respiratory chain complexes is

Coenzyme Q₁₀ (CoQ₁₀) is a ubiquitous factor present in cell membranes and mitochondria, both in its reduced (ubiquinol) and oxidized (ubiquinone) forms. Its levels are high in organs with high metabolism such as the heart, kidneys, and liver because it acts as an energy
