The key pathogenetic event of many retinopathies is apoptosis of retinal cells. Our previous studies have demonstrated that Coenzyme Q10 (CoQ10) prevents apoptosis of corneal keratocytes both in vitro and in vivo, by virtue of its ability to inhibit mitochondrial depolarization, independently of its free radical scavenger role. The aim of this study was to evaluate whether CoQ10 can protect cul...

OBJECTIVE An investigator-initiated, multicenter, randomized, placebo-controlled, double-blind clinical trial to determine whether coenzyme Q10 (CoQ10) is safe, well tolerated, and effective in slowing functional decline in progressive supranuclear palsy (PSP). METHODS Sixty-one participants received CoQ10 (2,400 mg/d) or placebo for up to 12 months. Progressive Supranuclear Palsy Rating Scal...

gamma-Tocopherol, the major form of dietary vitamin E, is absorbed in the intestine and is secreted in chylomicrons, which are then transferred to liver lysosomes. Most gamma-tocopherol is transferred to liver microsomes and is catabolized by cytochrome p450. Due to the hydrophobicity of gamma-tocopherol, a binding and transfer protein is plausible, but none have yet been isolated and character...

Coenzyme Q10 (CoQ10) is a key component of the mitochondrial electron transfer chain and is one of the most important cellular antioxidants. We previously reported that glycoprotein saposin B (SapB) binds CoQ10 in human cells. To elucidate the physiological role of SapB and its precursor, prosaposin (Psap), we prepared stable transfectants of HepG2 that overexpress wild-type human Psap (Wt-Tf)....

In 2001, we described six patients with cerebellar ataxia and severe deficiency of coenzyme Q10 (CoQ10, ubiquinone) in skeletal muscle [1]. Within one year, we described 13 additional patients [2]; therefore, we suspected this was not a very rare syndrome. Twelve years after our original report, cerebellar ataxia and atrophy has emerged as the most common clinical presentation of CoQ10 deficien...

BACKGROUND Low grade inflammation and oxidative stress are the key factors in the pathogenesis and development of diabetes and its complications. Coenzyme Q10 (CoQ10) is known as an antioxidant and has a vital role in generation of cellular energy providing. This study was undertaken to evaluate the effects of CoQ10 supplementation on lipid profiles and glycemic controls in patients with diabet...

Objective: To evaluate the effect of topical coenzyme Q10 (CoQ10) and vitamin E combination on tear function tests in glaucoma patients. Material Methods: A drop CoQ10 was inserted to one eye 28 patients with who have been using antiglaucomatous drops. The eyes that received constituted study group, other were part control group. Baseline, sixth, twelfth-month groups evaluated. Results: Baselin...

This study provides an information about the mechanisms of liver injury induced by CCl(4), and determines the influence of administration of L-carnitine or/and CoQ10 as prophylactic agents against CCl(4) deteriorative effect. The study was carried out on 80 adult male albino rats divided into eight groups, 10 animals each, as follows: four normal groups (control, treated with L-carnitine, treat...

Background: Polycystic ovary syndrome (PCOS) is one the most common diseases in women fertility age. PCOS alters ovarian follicles and affects blood lipid profiles, liver enzymes hormones. In this study, we tried to investigate effects of coenzyme Q10 (CoQ10) on pathological conditions. Methods: Twenty-four female rats were randomly divided into three groups; 1: control group, 2: group (receive...
