Oxidative stress is involved both in metabolic syndrome and male infertility. Hypogonadism is also associated with increased risk for cardiovascular disease. To investigate the role of gonadal steroids in systemic antioxidant regulation, we determined plasma CoenzymeQ(10) (CoQ(10)) and total antioxidant capacity (TAC) in postsurgical hypopituitaric patients. Twenty-six patients aged 28-55 years...

Phenotypical differences between muscle fibers are associated with a source of cellular energy. Coenzyme Q(10) (CoQ(10)) is a major component of the mitochondrial oxidative phosphorylation process, and it significantly contributes to the production of cellular energy in the form of ATP. The objective of this study was to determine the relationship between whole-tissue CoQ(10) content, mitochond...

Abstract We implement extraction of Coq programs to functional languages based on MetaCoq’s certified erasure. extend the MetaCoq erasure output language with typing information and use it as an intermediate representation, which we call ${\lambda^T_\square}$ . complement functionality a full pipeline that includes several standard transformations (e.g. eta-expansion inlining) implemented in pr...

OBJECTIVE To investigate the effects of fenofibrate and coenzyme Q(10) (CoQ) on diastolic function, ambulatory blood pressure (ABP), and heart rate (HR) in type 2 diabetic subjects with left ventricular diastolic dysfunction (LVDD). RESEARCH DESIGN AND METHODS We randomized, double-blind, 74 subjects to fenofibrate 160 mg daily, CoQ 200 mg daily, fenofibrate 160 mg plus CoQ 200 mg daily, or m...

The objective was to determine the impact of intact normoxic and hyperoxia-exposed (95% O(2) for 48 h) bovine pulmonary arterial endothelial cells in culture on the redox status of the coenzyme Q(10) homolog coenzyme Q(1) (CoQ(1)). When CoQ(1) (50 microM) was incubated with the cells for 30 min, its concentration in the medium decreased over time, reaching a lower level for normoxic than hypero...

BACKGROUND Fibromyalgia (FM) is a chronic pain syndrome with unknown etiology and a wide spectrum of symptoms such as allodynia, debilitating fatigue, joint stiffness and migraine. Recent studies have shown some evidences demonstrating that oxidative stress is associated to clinical symptoms in FM of fibromyalgia. We examined oxidative stress and bioenergetic status in blood mononuclear cells (...

In his timely article [1], Dr. P.K. Singal reviews the More recently, the results of 34 controlled clinical trials relationship between oxidative stress, antioxidants and and many open-label and long-term studies were reviewed cardiac diseases. This field is the most extensively investi[2]. The largest study to date involves 2359 patients and gated area of cardiovascular research with consequen...

The exact mechanisms underlying the role of oxidative stress in the pathogenesis and the prothrombotic or proinflammatory status of antiphospholipid syndrome (APS) remain unknown. Here, we investigate the role of oxidative stress and mitochondrial dysfunction in the proatherothrombotic status of APS patients induced by IgG-antiphospholipid antibodies and the beneficial effects of supplementing ...

Coenzyme Q10 (CoQ(10)) or ubiquinone is a well-known component of the mitochondrial respiratory chain. In humans, CoQ(10) deficiency causes a mitochondrial syndrome with an unexplained variability in the clinical presentations. To try to understand this heterogeneity in the clinical phenotypes, we have generated a Coq9 Knockin (R239X) mouse model. The lack of a functional Coq9 protein in homozy...
