Adriamycin inhibits the succinoxidase system and the NADH-oxidase system. Both of the intact mitocondrial enzymes and the pentane-extracted preparations are inhibited. The inhibition can be prevented by a molar ratio of coenzyme to adriamycin of 3:1 for coenzyme Q10 (ubiquinone), 5:1 for coenzyme Q7, and 5:1 for coenzyme Q4. Prevention of inhibition was observed in the decreasing order of coenz...
While some complementary and alternative techniques have been studied scientifically, high-quality data regarding safety, effectiveness, and mechanism of action are limited or controversial for most therapies. Whenever possible, it is recommended that practitioners be licensed by a recognized professional organization that adheres to clearly published standards. In addition, before starting a n...
CoQ10 was discovered by Dr. Frederick L. Crane at the University of Wisconsin in the late 1950s during his research on the biochemistry of the mitochondrial electron transport chain, also known as the respiratory chain. The pure substance isolated from beef heart mitochondria was sent to Dr. Karl Folkers at the pharmaceutical company Merck for identification and elucidation of its structure. It...
زمینه و هدف : استرس اکسیداتیو به عنوان یکی از دلایل ایجاد درد نوروپاتیک شناخته شده است و reactive oxygen species (ros) عامل ایجاد آن می باشد. کوآنزیم q10 به عنوان یک آنتی اکسیدان قادر به کاهش صدمات ناشی از استرس اکسیداتیو می باشد. این مطالعه به منظور تعیین اثر کوآنزیم q10 بر درد نوروپاتیک در مدل) (cci chronic crash injury روی موش صحرایی انجام شد. روش بررسی : این مطالعه تجربی روی 30 سر موش صحرای...
Single fiber recordings were made from auditory nerve fibers of the American bullfrog (Rana catesbeiana). As temperature was raised: (1) Best frequencies of fibers from the amphibian papilla (N = 15) increased. Below 600 Hz best frequency changes up to 0.06 oct/degrees C were found; above 600 Hz changes were less than 0.03 oct/degrees C. In the basilar papilla (N = 4) no significant increase of...
Purpose: The solubility of coenzyme Q10 (CoQ10) in water is extremely low, resulting in a low oral bioavailability. In this study, we attempted to improve the low dissolution and bioavailability of CoQ10, by means of the complexation with natural α-, βand γ-cyclodextrins (CyDs) and 2-hydroxypropyl-β-CyD (HP-β-CyD). Methods: The complexation of CoQ10 with CyDs was studied by the solubility metho...
It remains unclear how soil microbes respond to labile organic carbon (LOC) inputs and temperature sensitivity (Q10) of matter (SOM) decomposition is affected by LOC in a short-term. In this study, 13C-labeled glucose was added pristine grassland at four temperatures (10, 15, 20, 25 °C), the immediate utilization native SOM measured minutely We found that addition stimulated decomposition, elev...
Leopard frog saccular hair cells exhibit an electrical resonance in response to a depolarizing stimulus that has been proposed to contribute to the tuning properties of the frog sacculus by acting as an electrical band-pass filter. With the whole cell patch-clamp technique, we have investigated the effect of temperature on electrical resonances in isolated saccular hair cells, and we have descr...
Oxidation of low-density lipoprotein (LDL) has been strongly suggested as a key factor in the pathogenesis of atherosclerosis. Thus the inclusion of some anti-oxidant compounds such as Satureja Khozistanica,vitamin E and coenzyme Q10 in daily dietary food stuff may inhibit the production of oxidized LDL and may decrease both the development and the progression of atherosclerosis. The present st...
