Temperature sensitivity of soil respiration (Q10) is an important parameter on evaluations of feedback intensity between soil carbon efflux and global warming. Although experiments of soil respiration indicate its value has high spatial heterogeneity due to influences of many spatially heterogeneous environmental factors, the coupled climate-carbon cycle models usually assume it a globally inva...

The effects of the administration of water soluble coenzyme Q10 (25 mg/kg per day) over 30 days, after 50 days feeding on a high-fat diet (3% lard + 1.3% cholesterol), were investigated in the plasma and liver mitochondria of rabbits. Results showed that this atherogenic diet enhanced lipid levels both in plasma and liver mitochondria, reduced plasma and mitochondrial concentrations of retinol ...

Objective. This study aims to evaluate whether alpha-lipoic acid and/or coenzyme Q10 can protect the prepubertal ovarian tissue from ischemia-reperfusion injury in an experimental rat model of ovarian torsion. Materials and Methods. Forty-two female preadolescent Wistar-Albino rats were divided into 6 equal groups randomly. The sham group had laparotomy without torsion; the other groups had tor...

Skeletal muscle function largely depend on intact energy metabolism, stress response, and antioxidant defense mechanisms. In this study, we tested the effect of a combined supplementation of α-lipoic acid (LA) plus coenzyme Q10 (Q10) on PPARγ-coactivator α (PGC1α) activity, expression of glutathione-related phase II enzymes and glutathione (GSH) levels in cultured C2C12 myotubes. Supplementatio...

Treatment of hypercholesterolemia with statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) is effective in the primary and secondary prevention of cardiovascular disease. However, statin use is often associated with a variety of muscle-related symptoms or myopathies. Myopathy may be related in part to statin inhibition of the endogenous synthesis of coenzyme Q10, an essential c...

BACKGROUND Coenzyme Q10 is commonly used to treat congestive heart failure on the basis of data from several unblinded, subjective studies. Few randomized, blinded, controlled studies have evaluated objective measures of cardiac performance. OBJECTIVE To determine the effect of coenzyme Q10 on peak oxygen consumption, exercise duration, and ejection fraction. DESIGN Randomized, double-blind...

INTRODUCTION Dyslipidemia and high serum lipoprotein(a) are among the risk factors for cardiovascular diseases in hemodialysis patients. Statins as a first line of therapy in hyperlipidemia does not always reduce the serum lipoprotein(a) level. Several studies have reported the lipid-lowering effects of carnitine and coenzyme Q10 in hemodialysis patients. This study was designed to investigate ...

BACKGROUND It has been demonstrated that glucose transporter (GLUT1) deficiency in a mouse model causes a diminished cerebral lipid synthesis. This deficient lipid biosynthesis could contribute to secondary CoQ deficiency. We report here, for the first time an association between GLUT1 and coenzyme Q10 deficiency in a pediatric patient. CASE PRESENTATION We report a 15 year-old girl with trun...
