There is significant interest in coenzyme Q10(CoQ10) as a potential treatment for neurodegenerative diseases and in its promise as a neuroprotectant. Experimental studies indicate that CoQ10 can protect against brain disorders by inhibiting neuronal damage. There is a need to demonstrate CSF levels of CoQ10 in humans. Subjects and Methods: After clearance from the hospital ethical committee, al...

Protection against oxidative damage caused by excessive reactive oxygen species (ROS) by an antioxidant network is essential for the health of tissues, especially in the cardiovascular system. Here, we identified a gene with important antioxidant features by analyzing a null allele of zebrafish ubiad1, called barolo (bar). bar mutants show specific cardiovascular failure due to oxidative stress...

Although it was first described in 1989, our understanding of coenzyme Q10 (CoQ10) deficiency is only now coming of age with the recent first description of the underlying molecular defects. The diverse clinical presentations, classifiable into four major syndromes, raise the question as to whether the deficiencies are primary or secondary. Recent studies, including the one by Mollet, Rötig, an...

Heart failure affects 5.1 million people in the USA annually. It accounts for a frequent cause of hospitalizations and disability. Patients with congestive heart failure have lower plasma levels of CoQ10, which is an independent predictor of mortality in this patient population. It has been hypothesized that a deficiency of CoQ10 can play a role in the development and worsening of heart failure...

For a number of years, coenzyme Q (CoQ10 in humans) was known for its key role in mitochondrial bioenergetics; later studies demonstrated its presence in other subcellular fractions and in plasma, and extensively investigated its antioxidant role. These two functions constitute the basis on which research supporting the clinical use of CoQ10 is founded. Also at the inner mitochondrial membrane ...

BACKGROUND Acute liver damage may be followed by biochemical, behavioral, and pathological alterations, which can result in serious complications and even death. OBJECTIVES In this experimental study we determined whether coenzyme Q10 (CoQ10), a common supplementary medicine known to have protective, antioxidative, and anti-inflammatory effects in cells, has any protective effect against thio...

OBJECTIVE To investigate the effect of CoenzymeQ10 (CoQ10) on pain severity and cartilage degeneration in an experimental model of rat osteoarthritis (OA). MATERIALS AND METHODS OA was induced in rats by intra-articular injection of monosodium iodoacetate (MIA) to the knee. Oral administration of CoQ10 was initiated on day 4 after MIA injection. Pain severity was assessed by measuring seconda...

Natural lipophilic bioactives that possess human health benefits, such as coenzyme Q10 (CoQ10) and R-α-lipoic acid (RALA), often have undesirable characteristics that limit their use as nutraceuticals and cosmeceuticals. These bioactives are usually unstable against oxygen, ultraviolet light, low pH and heat. Furthermore, their watersolubility is low because of their hydrophobic nature or insta...

Intensive physical exercise may cause muscular injury and increase oxidative stress. The purpose of this study was to examine the effect of an antioxidant, coenzyme Q10 (CoQ10), on muscular injury and oxidative stress during exercise training. Eighteen male students, all elite Japanese kendo athletes, were randomly assigned to either a CoQ10 group (n 10) or a placebo group (n 8) in a double-bli...

CoenzymeQ10 (CoQ10) is used as a food supplement and as an ethical drug because of its antioxidant functions and key role in mitochondrial bioenergetics. In this study, the effects of CoQ10 on blood biochemistry and malondialdehyde (MDA) levels in rats were investigated. Ten male Wistar rats ages ranging between 7 and 8 weeks were used. All animals were kept under the same condition and were gi...
