Freya L Sheeran, Salvatore Pepe
Energy insufficiency has been recognized as a key feature of systolic heart failure. Although mitochondria have long been known to sustain myocardial work energy supply, the capacity to therapeutically target mitochondrial bioenergetics dysfunction is hampered by a complex interplay of multiple perturbations that progressively compound causing myocardial failure and collapse. Compared to non-failing human donor hearts, activity rates of complexes I and IV, nicotinamide nucleotide transhydrogenase (NADPH-transhydrogenase, Nnt) and the Krebs cycle enzymes isocitrate dehydrogenase, malate dehydrogenase and aconitase are markedly decreased in end-stage heart failure...

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...

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...

R Sangermani, A Boncimino
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...

Coenzyme Q10 (CoQ10 ) plays a crucial role in mitochondria as an electron carrier within the mitochondrial respiratory chain (MRC) and is an essential antioxidant. Mutations in genes responsible for CoQ10 biosynthesis (COQ genes) cause primary CoQ10 deficiency, a rare and heterogeneous mitochondrial disorder with no clear genotype-phenotype association, mainly affecting tissues with high-energy demand including brain and skeletal muscle (SkM). Here, we report a four-year-old girl diagnosed with minor mental retardation and lethal rhabdomyolysis harboring a heterozygous mutation (c...

Inflammation plays critical roles in the pathogenic mechanisms of several neurodegenerative disorders including Alzheimer's disease (AD). Previous study revealed that CoQ10 augmented cellular antioxidant defense capacity, thereby protecting PC12 cells from oxidative neurotoxicity. However, the mechanism by which CoQ10 inhibits inflammation remains unknown. In this study, we aim to examine the effects of CoQ10 on Aβ25-35-induced inflammatory in PC12 cells and the underlying molecular mechanism of its neuroprotective action...
