Strenuous exercise (any activity that expends six metabolic equivalents per minute or more causing sensations of fatigue and exhaustion to occur, inducing deleterious effects, affecting negatively different cells), induces muscle damage and hematological changes associated with high production of
Clinical evidence demonstrates that ubiquinol-10, the reduced active form of coenzyme Q10 (CoQ10H₂), improves endothelial function through its antioxidant and probably its anti-inflammatory properties. We previously reported that a biomarker combination including miR-146a, its target protein IL-1
Hemorrhagic shock (HS) is a leading cause of death in traumatic injury. Ischemia and hypoxia in HS and fluid resuscitation (FR) creates a condition that facilitates excessive generation of reactive oxygen species (ROS). This is a major factor causing increased leukocyte-endothelial cell adhesive
BACKGROUND
Coenzyme Q₁₀ is an essential cofactor in the respiratory chain and serves in its reduced form, ubiquinol, as a potent antioxidant. Studies in vitro and in vivo provide evidence that ubiquinol reduces inflammatory processes via gene expression. Here we investigate the putative link between
Coenzyme Q(10) is an essential cofactor in the respiratory chain and serves as a potent antioxidant in biological membranes. Recent studies in vitro and in vivo provide evidence that Coenzyme Q(10) is involved in inflammatory processes and lipid metabolism via gene expression. To study these effects
Oxygen/nitrogen reactive species (ROS/RNS) are currently implicated in the pathogenesis of ulcerative colitis, drawing attention on the potential prophylactic and healing properties of antioxidants, scavengers, chelators. We evaluated the possible protective/curative effects of a natural antioxidant
Studies in vitro and in mice indicate a role for Coenzyme Q(10) (CoQ(10) ) in gene expression. To determine this function in relationship to physiological readouts, a 2-week supplementation study with the reduced form of CoQ(10) (ubiquinol, Q(10) H(2) , 150 mg/d) was performed in 53 healthy males.
OBJECTIVE
Fatigue is the most common and distressing symptom reported by cancer patients during and after treatment. Tumor growth increases oxidative stress and cytokine production, which causes skeletal muscle wasting and cardiac dysfunction. The purpose of this study was to determine whether
BACKGROUND
The reduced form of Coenzyme Q10 (CoQ10), ubiquinol (Q10H2), serves as a potent antioxidant in mitochondria and lipid membranes. There is evidence that Q10H2 protects against oxidative events in lipids, proteins and DNA. Serum gamma-glutamyltransferase (GGT) activity is associated with
Statins are potent cholesterol-lowering drugs and are generally well tolerated. Hepatotoxicity is a rare but serious adverse effect of statins; however, its mechanisms are not clear. Coenzyme Q10 deficiency has been suggested, and supplementation of reduced coenzyme Q10 (ubiquinol) has been shown to
BACKGROUND
We previously found decreased levels of Coenzyme Q10 (CoQ10) in patients with septic shock. The objective of the current study was to assess whether the provision of exogenous ubiquinol (the reduced form of CoQ10) could increase plasma CoQ10 levels and improve mitochondrial
MicroRNAs (miRs) are involved in key biological processes via suppression of gene expression at posttranscriptional levels. According to their superior functions, subtle modulation of miR expression by certain compounds or nutrients is desirable under particular conditions. Bacterial
BACKGROUND
There is evidence that both carnitine and coenzyme Q 10 (Co Q), which are important for the functioning of myocardial mitochondria, are deficient in patients with congestive heart failure, in association with increased pro-inflammatory cytokines. It is possible that supplementation with
The prevalence of allergies and asthma among the world's population has been steadily increasing due to environmental factors. It has been described that exposure to ozone, diesel exhaust particles, or tobacco smoke exacerbates allergic inflammation in the lungs. These environmental oxidants
Experimental approaches designed to define the role of reactive oxygen and nitrogen species generated by inflammatory cells in the tissue injury seen in inflammatory bowel disease rarely consider the chemical antioxidant defences against such increased oxidant stress in the mucosa. In this
