BACKGROUND No data are available on the presence and content of Coenzyme Q10 (CoQ10) in human follicular fluid and its role. OBJECTIVE To assess the presence and concentration of CoQ10 in human follicular fluid in relation to oocyte fertilization. METHODS CQ10 content was measured in follicular fluid obtained from 20 infertile women undergoing ovarian(More)
Down syndrome (DS) is a chromosomal abnormality (trisomy 21) associated with mental retardation and Alzheimer-like dementia, characteristic change of the individual's phenotype and premature ageing. Oxidative stress is known to play a major role in this pathology since a gene dose effect leads to elevated ratio of superoxide dismutase to(More)
Human NAD(P)H: quinone oxidoreductase 1 (NQO1) catalyzes the obligatory two-electron reduction of quinones. For this peculiar catalytic mechanism, the enzyme is considered an important cytoprotector. The NQO1 gene is expressed in all human tissues, unless a polymorphism due to C609T point mutation is present. This polymorphism produces a null phenotype in(More)
Circulating miR-126-3p levels were determined in 136 healthy subjects (CTRs) aged 20-90 years and 193 patients with type-2 diabetes mellitus (T2DMs) aged 40-80 years, to explore the combined effect of age and glycemic state on miR-126-3p expression. Moreover, intra/extracellular miR-126-3p levels were measured in human endothelial cells (HUVECs) undergoing(More)
Clinical evidence demonstrates that ubiquinol-10, the reduced active form of coenzyme Q10 (CoQ10H₂), improves endothelial function through its antioxidant and probably its anti-inflammatory properties. We previously reported that a biomarker combination including miR-146a, its target protein IL-1 receptor-associated kinase (IRAK-1), and released interleukin(More)
BACKGROUND Antioxidants are now being incorporated into sunscreens as additional topical measure for delaying the aging process and reducing photo-damage to skin induced by excessive UVA exposure. UVA radiation reaching the skin leads to the generation of ROS (reactive oxygen species) implicated in DNA damage and activation of matrix metalloproteinase-1(More)
Oxidative stress is known to play a relevant role in Down syndrome (DS) and its effects are documented from embryonic life. Oxidative DNA damage has been shown to be significantly elevated in Down syndrome patients, and this has been indicated as an early event promoting neurodegeneration and Alzheimer type dementia. The aim of this study was to investigate(More)
Olive oil consumption is associated with protective cardiovascular properties, including some beneficial modifications in lipoprotein profile and composition. Coenzyme Q(10) (CoQ(10)) exerts a protective effect on plasma lipoproteins. Aim of the study was to investigate whether extra virgin (EV) olive oil enriched with CoQ(10) affects CoQ(10) levels and(More)
Data normalization of gene expression on human dermal fibroblasts (HDF) exposed to UVA has commonly been done using either GAPDH or β-actin as reference genes without any validation of their expression stability. Since this aspect, important for accurate normalization, has been overlooked, we aimed to establish a suitable set of reference genes for studies(More)
BACKGROUND UVA rays present in sunlight are able to reach the dermal skin layer generating reactive oxygen species (ROS) responsible for oxidative damage, alterations in gene expression, DNA damage, leading to cell inflammation, photo-ageing/-carcinogenesis. Sunscreens contain UV filters as active ingredients that absorb/reflect/dissipate UV radiation:(More)
