(1) Background: Hepatocellular carcinoma (HCC) is the second leading cause of cancer deaths worldwide, and surgical resection is the main treatment for HCC. To date, no published study has examined the status of coenzyme Q10 in patients with HCC after surgery. Thus, the purpose of this study was to investigate the correlations between the level of coenzyme Q10, oxidative stress, and inflammatio...

Many conditions associated with male infertility are inducers of oxidative stress, including varicocele. Antioxidants, such as coenzyme Q10, may be useful in this case. To evaluate the antioxidant capacity of seminal plasma of infertile men with varicocele before and after an oral supplementation with coenzyme Q10 , 38 patients were recruited from a pilot clinical trial. A standard semen analys...

Type 2 diabetes mellitus (T2DM) is a major cause of morbidity and mortality with ever increasing prevalence in the United States and worldwide. There is growing body of evidence suggesting that mitochondrial dysfunction secondary to oxidative stress plays a critical role in the pathogenesis of T2DM. Coenzyme Q10 is an important micronutrient acting on the electron transport chain of the mitocho...

RATIONALE Mitochondrial nephropathy has a poor prognosis and often progresses to the end-stage renal disease. Renal pathology often is focal segmental glomerulosclerosis (FSGS) and does not respond to steroid therapy or immunosuppressive therapy. Some patients are benefited from the therapy of coenzyme Q10, which affect the synthesis pathway of coenzyme Q10. PATIENT CONCERNS Herein, we report...

Problem statement: Hyperlipidemia is well known to play a main role in the development of atherosclerosis. It is characterized by abnormally elevated cholesterol, triglyceride, low density lipoprotein cholesterol and very low density lipoprotein cholesterol levels in the blood. It has been recognized for many years that hypercholesterolemia is a major risk factor for cardiovascular diseases suc...

occurrenceofoxidative stress (os) following in vitro culture is inescapable. therefore, the aim of the present study was to determine the efficacy of coenzyme q 10 (coq 10 ) supplementation medium on developments and total antioxidant capacity (tac) of mouse vitrified pre-antral follicles. fresh and vitrified-warmed isolated preantral follicles from ovaries of 14-16 day s -old mice were cultured...

background: fatigue is a common side effect in cancer patients undergoing radiation therapy (rt). radiation-induced fatigue affects the quality of life, but there is no definitive treatment option. in this study, the weight-loaded forced swim test was performed to assess the effect of coenzyme q10 (coq10) on radiation-induced fatigue. materials and methods: a total of 60 rats were divided rando...

This report describes an intervention study with healthy volunteers (20 smokers, 28 non-smokers) taking a food additive mainly containing vitamin C (ascorbic acid), vitamin E (alpha-tocopherol), ubiquinone (Q10), vitamin A and zinkoxide for four weeks in a double blind, randomized and placebo controlled manner. Before and after the intervention blood was withdrawn and general blood parameters w...

It is well known that ubiquinone-10 (coenzyme Q10, ubiquinone 50) acts as an electron carrier of the respiratory chain in mitochondria. In this paper we show that ubiquinol-10, the reduced form of ubiquinone-10, also efficiently scavenges free radicals generated chemically within liposomal membranes. Ubiquinol-10 is about as effective in preventing peroxidative damage to lipids as alpha-tocophe...
