The temperature sensitivity (Q10) of soil heterotrophic respiration (Rh) is an important ecological model parameter and may vary with temperature and moisture. While Q10 generally decreases with increasing temperature, the moisture effects on Q10 have been controversial. To address this, we conducted a 90-day laboratory incubation experiment using a subtropical forest soil with a full factorial...

BACKGROUND The therapeutic efficacy of coenzyme Q10 on patients with cardiac failure remains controversial. We pooled previous clinical studies to re-evaluate the efficacy of coenzyme Q10 in patients with cardiac failure. METHODS We searched PubMed, Cochrane Library, EMBASE, and Clinical Trials.gov databases for controlled trials. The endpoints were death, left heart ejection fraction, exerci...

BACKGROUND Heavy exercise cause muscle damage associated with production of inflammatory agents. The purpose of present study was to determine the effect of acute and 14-day Coenzyme Q10 supplementation on inflammatory, blood lactate and muscle damage in male middle-distance runners. METHODS Eighteen male middle-distance runners in a randomized and quasi experimental study were allocated into...

Murine natural killer (NK) cells are regulated by the interaction of Ly49 receptors with major histocompatibility complex class I molecules (MHC-I). Although the ligands for inhibitory Ly49 were considered to be restricted to classical MHC (MHC-Ia), we have shown that the non-classical MHC molecule (MHC-Ib) H2-M3 was a ligand for the inhibitory Ly49A. Here we establish that another MHC-Ib, H2-Q...

BACKGROUND It has been reported that higher levels of oxidative stress and inflammation play a key role in the progression of hepatocellular carcinoma (HCC) after surgery. Coenzyme Q10 is an endogenous lipid-soluble antioxidant. To date, no intervention study has investigated coenzyme Q10 supplementation in HCC patients after surgery. The purpose of this study was to investigate oxidative stres...

The basal respiration rate at 10°C (R10) and the temperature sensitivity of soil respiration (Q10) are two premier parameters in predicting the instantaneous rate of soil respiration at a given temperature. However, the mechanisms underlying the spatial variations in R10 and Q10 are not quite clear. R10 and Q10 were calculated using an exponential function with measured soil respiration and soi...

todays, parallel to growing in acceptance of functional products, various additives are used to improve the characteristics of functional food products. the coenzyme q10 is an essential component for energy conversion and production of adenosine triphosphate (atp) in the membranes of all body cells and organelles, especially the inner mitochondrial membrane is found. coenzyme q10 plays a vital ...

OBJECTIVE To examine whether coenzyme Q10, a potent antioxidant, is associated with risk of dementia, which has not yet been elucidated. APPROACH AND RESULTS We performed a case-control study nested in a community-based cohort of approximately 6000 Japanese aged 40-69 years at baseline (1984-1994). Serum coenzyme Q10 was measured in 65 incident cases of disabling dementia with dementia-relate...
