BACKGROUND Neuropathic pain (NP) is one of the most suffering medical conditions that often fail to respond to certain pain therapy. Although its exact etiology is still unknown the role of reactive oxygen species (ROS) and oxidative stress were explored by many researchers. Neuropathies either central or peripheral lead to painful condition as well as social and economic isolation, thus variou...

The study was performed to see the effects of coenzyme Q10 (CoQ10) on blood biochemical components and hepatic antioxidant system in rats exposed to lipopolysaccharide (LPS)-induced toxicity. A total of 24 rats were allocated to four groups: control (CON), 100 mg/kg BW of LPS (LPS), 100 mg of CoQ10/kg BW with LPS (LCQI) and 300 mg of CoQ10/kg BW with LPS (LCQII). The LPS and LCQI groups showed ...

The objective of this experiment was to study the effect of dietary supplementation of Coenzyme Q10 on broiler growth rate, carcass characteristics and cost of production. A biological trial was carried out with 270 broiler chicks fed with coenzyme Q10 at 0, 20 and 40 mg/kg of diet at each of the three energy levels. At the end of 42 days growth period the birds were sacrificed and the samples ...

low, particularly when it is 0.6, the dispersion of values for any individual will span only a small part of the reference interval. Reference values will thus be of little use, in particular for deciding whether a significant change has occurred. Conversely, when the index is high, particularly when it is 1.4, values from a single individual will cover much of the entire distribution of the re...

Using brain mitochondria isolated from 20-month-old diabetic Goto-Kakizaki rats, we evaluated the efficacy of CoQ10 treatment against mitochondrial dysfunction induced by Abeta1-40. For that purpose, several mitochondrial parameters were evaluated: respiratory indexes (RCR and ADP/O ratio), transmembrane potential (DeltaPsim), repolarization lag phase, repolarization and ATP levels and the capa...

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...

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)....

BACKGROUND Low plasma concentrations of coenzyme Q10 (CoQ10) have been associated with concentration of lipoproteins and other factors contributing to coronary heart diseases. OBJECTIVES The present investigation aimed to improve the blood pressure and serum lipoproteins concentration in patients with myocardial infarction (MI) by CoQ10 supplementation. PATIENTS AND METHODS In this randomiz...
