No consensus exists regarding soil organic carbon (SOC) lability and the temperature sensitivity of its decomposition. This lack of clear understanding limits the accuracy in predicting the long-term impacts of climate change on soil carbon (C) storage. In this study, we determined the temperature responses of labile and recalcitrant organic carbon (LOC vs. ROC) by comparing the time required t...

Current treatment options for parkinsonism as a neurodegenerative disease are limited and still mainly symptomatic and lack significant disease-modifying effect. Understanding its molecular pathology and finding the cause of dopaminergic cell loss will lead to exploring therapies that could prevent and cure the disease. Mitochondrial dysfunction was found to stimulate releasing of reactive oxyg...

The aim of this study was to determine the effects of co-Q10 and ellagic acid on sperm parameters after the freeze–thawing of Ghezel ram sperm. Twenty ejaculates from five Ghezel rams were collected in this study. Semen samples, which were diluted with a soybean lecithin (SL) based extender containing 0.25 mM ellagic acid, 0.5 μM co-Q10, 0.25 mM ellagic acid + 0.5 μM co-Q10 and no antioxidant (...

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 i...

Understanding the functional relationship between greenhouse gas fluxes and environmental variables is crucial for predicting the impacts of wetlands on future climate change in response to various perturbations. We examined the relationships between methane (CH4) emission and temperature in two marsh stands dominated by the Phragmites australis and Cyperus malaccensis, respectively, in a subtr...

Mitochondrial redox imbalance has been implicated in mechanisms of aging, various degenerative diseases and drug-induced toxicity. Statins are safe and well-tolerated therapeutic drugs that occasionally induce myotoxicity such as myopathy and rhabdomyolysis. Previous studies indicate that myotoxicity caused by statins may be linked to impairment of mitochondrial functions. Here, we report that ...

The microbial decomposition respiration of plant litter generates a major CO2 efflux from terrestrial ecosystems that plays a critical role in the regulation of carbon cycling on regional and global scales. However, the respiration from root litter decomposition and its sensitivity to temperature changes are unclear in current models of carbon turnover in forest soils. Thus, we examined seasona...
