BACKGROUND The combination of a small pool of patients at any given time with the availability of many potential neuroprotective agents to be tested in ALS requires efficient phase II trial designs. OBJECTIVE To describe the design of the Clinical Trial of High Dose Coenzyme Q10 (CoQ10) in ALS (QALS study)--a phase II, randomized, placebo-controlled, double-blind, multicenter clinical trial. ...

AIM Myocardial infarction (MI) due to sudden occlusion of a major coronary artery leads to a complex series of events that result in left ventricle (LV) impairment eventual heart failure. Therapeutic options are limited to reverse such trends post MI. The aim of this study was to compare the acute cardioprotective effects of the antioxidants, resveratrol (RES) and coenzyme Q10 (CoQ10), either i...

Although coenzyme Q10 (CoQ10) serves as an antioxidant and energy source for spermatozoa when added to stallion semen before cooling or freezing, the effects of feeding CoQ10 on quality have not been studied. We assessed daily oral ingestion CoQ10-ubiquinol by stallions their plasma concentrations quality. Seven mature Andalusian ate 1g ubiquinol/day 4 weeks followed a 4-week washout period. Fo...

Background: Polycystic ovary syndrome (PCOS) is the largest single cause of anovulatory infertility. PCOS associated with oxidative stress. Coenzyme q10 (Coq10) an antioxidant that protects mitochondria from damage caused by either insulin resistance or free radicals. The objective study was to compare effect combined Coq10 and letrozole than alone for ovulation induction in women PCOS.Methods:...

Background: Paraquat (PQ), an herbicide, is a very poisonous compound for both humans and animals. This study was conducted to examine the protective effect of the Coenzyme Q10 (CoQ10) in newborn rats from pregnant rats pre-treated with PQ. Methods: The experiments were conducted on 25 rats, divided in five groups randomly and equally: 1 - Control Group received normal saline (0.1ml/day); 2...

The present study aims to examine the effects of orally administered coenzyme Q10 (CoQ10) supplement on certain haematological and biochemical parameters in regularly exercising elite endurance athletes. The study subjects were divided into three groups, namely the control group (n = 5) and two subject groups taking 100 mg (n = 5) and 200 mg (n = 5) CoQ10. The blood samples thus collected were ...

BACKGROUND Therapeutic hypothermia can improve survival after cardiopulmonary resuscitation (CPR). Coenzyme Q10 (CoQ10) has shown a protective effect in neurodegenerative disorders. We investigated whether combining mild hypothermia with CoQ10 after out-of-hospital cardiac arrest provides additional benefit. METHODS AND RESULTS Forty-nine patients were randomly assigned to either hypothermia ...

Coenzyme Q10 is an essential cofactor in the electron transport chain and serves as an important antioxidant in both mitochondria and lipid membranes. CoQ10 is also an obligatory cofactor for the function of uncoupling proteins. Furthermore, dietary supplementation affecting CoQ10 levels has been shown in a number of organisms to cause multiple phenotypic effects. However, the molecular mechani...

Low seminal plasma concentrations of coenzyme Q10 (CoQ10) have been correlated with impaired sperm parameters, but the exact mechanism remains of dominating interest. This randomised, placebo-controlled study examined the effect of CoQ10 on catalase, superoxide dismutase (SOD) and F2 -isoprostanes in seminal plasma in infertile men and their relation with CoQ10 concentration. Sixty infertile me...

Coenzyme Q10 (CoQ10) plays an important role in bioenergetic processes and has antioxidant activity. Fifteen exercise-trained individuals (10 men and 5 women; 30-65 years) received reduced CoQ10 (Kaneka QH ubiquinol; 300 mg per day) or a placebo for four weeks in a random order, double blind, cross-over design (3 week washout). After each four-week period, a graded exercise treadmill test and a...
