Coenzyme Q10 (CoQ10) is a mitochondrial-targeted antioxidant with known neuroprotective activity. Its ocular effects when co-solubilised with α-tocopherol polyethylene glycol succinate (TPGS) were evaluated. In vitro studies confirmed that CoQ10 was significantly protective in different retinal ganglion cell (RGC) models. In vivo studies in Adult Dark Agouti (DA) rats with unilateral surgically-induced ocular hypertension (OHT) treated with either CoQ10/TPGS micelles or TPGS vehicle twice daily for three weeks were performed, following which retinal cell health was assessed in vivo using DARC (Detection of Apoptotic Retinal Cells) and post-mortem with Brn3a histological assessment on whole retinal mounts...

The benthic life stage (polyp or scyphistoma) of the bloom-forming jellyfish, Aurelia aurita (Linnaeus, 1759), also known as the moon jellyfish, contributes to the seasonal occurrence and abundance of medusa blooms via asexual reproduction. A. aurita is widely distributed in coastal areas in northern Europe, and one of the most studied jellyfish species. While the physiology of the visible medusa is largely understood, understanding of the physiology of the perennial benthic life-stage is scarce. To measure the physiological tolerance of A...

BACKGROUND: Statins represent a group of drugs that are currently indicated in the primary and secondary prevention of cardiovascular events. Their administration can be associated with side effects and the insufficient reduction of triacylglyceride (TAG) levels. This study aimed to assess the effect of the triple combination of statins with omega-3 fatty acids and coenzyme Q10 (CoQ10) on parameters associated with atherogenesis and statin side effects. MATERIALS AND METHODS: In this pilot randomized double-blind trial, 105 subjects who met the criteria of combined dislipidemia and elevated TAG levels were randomly divided into three groups...

Quantifying the adjustments of leaf respiration in response to seasonal temperature variation and climate warming is crucial because carbon loss from vegetation is a large but uncertain part of the global carbon cycle. We grew fast-growing Eucalyptus globulus Labill. trees exposed to +3 °C warming and elevated CO2 in 10-m tall whole-tree chambers and measured the temperature responses of leaf mitochondrial respiration, both in light (RLight) and in darkness (RDark), over a 20-40 °C temperature range and during two different seasons...

Coenzyme Q10 (CoQ10) or ubiquinone is one of the two electron carriers in the mitochondrial respiratory chain which has an essential role in the process of oxidative phosphorylation. Defects in CoQ10 synthesis are usually associated with the impaired function of CoQ10-dependent complexes I, II and III. The recessively transmitted CoQ10 deficiency has been associated with a number of phenotypically and genetically heterogeneous groups of disorders manifesting at variable age of onset. The infantile, multisystemic presentation is usually caused by mutations in genes directly involved in CoQ10 biosynthesis...

Dongjia Xing, Qin Gong
The medial olivocochlear (MOC) bundle is an auditory nucleus that projects efferent nerve fibers to the outer hair cells (OHCs) for synaptic innervation. The aim of the present study was to investigate the possible existence of frequency and ear specificity in MOC efferent modulation, as well as how MOC activation influences cochlear tuning. Stimulus frequency otoacoustic emissions (SFOAEs) were used to study MOC efferent modulation. Therefore, the current experiment was designed to compare the degree of SFOAE suppression in the both ears of 20 individuals at 1, 2, 4, and 8 kHz...

CO2 efflux (ECO2) from stems and branches is highly variable within trees. To investigate the mechanisms underlying the temporal dynamics and vertical variations in ECO2, we measured the stem ECO2 by infrared gas analysis (IRGA) and meteorological conditions at 10 different heights from 0.1 to 3.7 m aboveground on two consecutive days every month for 1 year in six Styphnolobium japonicum trees with a similar size. The results indicated that the seasonal change in ECO2 roughly followed the seasonal variations in woody tissue temperature (TW) and stem radial diameter increment (Di)...

We investigate the solution and fibril conformations and structural transitions of the polyglutamine (polyQ) peptide, D2Q10K2 (Q10), by synergistically using UV Resonance Raman (UVRR) spectroscopy and Molecular Dynamics (MD) simulations. We show that Q10 adopts two distinct, monomeric solution conformational states, a collapsed β-strand and a PPII-like structure that do not readily interconvert. This clearly indicates a high activation barrier in solution that prevents equilibration between these structures...

Nutraceutics are the most used non-pharmacological remedies for migraine's prophylaxis in children and adolescents. Doctors interested in use of nutraceuticals for a complete treatment of children's headache should be adequately informed on this treatments' efficacy and safety. Actually there is a lack of official guidelines about use of nutraceuticals in migraine's prevention in children and adolescent and there are few studies with limited efficacy evidences. The most used nutraceuticals for adolescent's and children's headache prophylaxis are: magnesium, coenzyme Q10, riboflavin, butterbur, feverfew and melatonin...

Several studies have supported the efficacy of complementary and alternative medicine approaches (physical, behavioral and nutraceutical therapies) in the treatment of headache disorders. Nutraceutical treatment consists of taking vitamins, supplements (magnesium, riboflavin, coenzyme Q10, and alpha lipoic acid) and herbal preparations (feverfew and butterbur), and its usage is frequently determined by dissatisfaction with conventional medical therapies. There is a growing body of research on nutraceutical use for migraine prophylaxis...

The present study showed the development of nanocapsules containing the association of the coenzyme Q10 and vitamin E acetate and the evaluation of their effect on in vitro cells culture of malignant glioma and melanoma. In order to investigate if nanocapsules are able to protect coenzyme Q10 from degradation under UVC radiation, a photostability study was carried out. For this, three concentrations of vitamin E acetate were evaluated (1, 2 or 3%). Nanocapsules presented suitable physicochemical characteristics and were able to protect coenzyme Q10 from photodegradation...

BACKGROUND: Coenzyme Q10 (CoQ10) is a naturally occurring, lipid-soluble antioxidant and an essential electron carrier in the mitochondrial respiratory chain. In sepsis, CoQ10 deficiency induced by mitochondrial failure can lead to hypoxia, hypoperfusion, oxidative organ damage and finally death. We aimed to investigate the effects of CoQ10 on survival, mesenteric artery blood flow (MABF), vascular reactivity, oxidative and inflammatory injuries in cecal ligation and puncture (CLP)-induced sepsis...

Understanding soil CO2 flux temperature sensitivity (Q10) is critical for predicting ecosystem-level responses to climate change. Yet, the effects of warming on microbial CO2 respiration still remain poorly understood under current Earth system models, partly as a result of thermal acclimation of organic matter decomposition. We conducted a 117-day incubation experiment under constant and diurnally-varying temperature treatments based on four forest soils varying in vegetation stand and soil horizon. Our results showed that Q10 was greater under varying than constant temperature regimes...

We investigated the effects of co-enzyme Q10 (Q10) and acetyl salicylic acid (ASA) on expression of Hsp70 in the protection of primary chicken myocardial cells during heat stress. Western blot analysis showed that Q10 and ASA accelerated the induction of Hsp70 when chicken myocardial cells were exposed to hyperthermia. In the absence of heat stress, however, neither Q10 nor ASA are able to upregulate Hsp70 expression. Analysis of enzymes that respond to cellular damage and pathological examination revealed that ectopic expression of ASA and Q10 alleviate cellular damage during heat stress...

Isolated abnormalities in terminal regions of chromosomes 10q and 22q were formerly described in patients affected by neuropsychological impairment, abnormal facies, and heterogeneous structural abnormalities of the body. Chromosomes 10q and 22q harbor important genes that play a major role in CNS development, like DOCK1 and SHANK3, and in overall body growth, like FGFR2 and HTRA1. By using clinical, neuroradiological, neurophysiological, and genetic assessment, we studied 3 siblings affected by 2 different forms of very severe neuropsychological impairment with structural physical abnormalities, epilepsy, and body overgrowth...
