OBJECTIVE There is plenty of evidence that osteoprotegerin (OPG) is linked to subclinical vascular damage and predicts cardiovascular disease in high-risk populations. Our aim is to investigate the relationships of OPG/free soluble receptor activator of nuclear factor κB ligand (sRANKL) to insulin resistance, brachial artery flow-mediated vasodilation(More)
Nanosized particles (NPs) have recently been proposed for extensive use, including into the biomedical field. As a result, research on toxicity and oxidative stress concerning the interaction of nanoparticle and the living organism has attracted increasing interest among specialists. Two different targets have been the motor of this type of research: 1) the(More)
BACKGROUND We are hereby investigating for the first time the effect of the association ethinylestradiol30μg-drospirenone 3mg (DRP/EE30μg) plus metformin and weight loss on endothelial status and C-reactive protein (hsCRP) levels in polycystic ovary syndrome (PCOS). METHODS 25 young women with PCOS (mean age 22.76 ± 0.83 years, body mass index (BMI):(More)
BACKGROUND Noble metal nanoparticles such as gold nanoparticles can strongly absorb light in the visible region by inducing coherent collective oscillation of conduction band electrons in strong resonance with visible frequencies of light. This phenomenon is frequently termed as surface plasmon resonance (SPR). OBJECTIVES The main objective was to study(More)
Pancreatic cancer (PC) is one of the most lethal solid tumor in humans, with an overall 5-year survival rate of less than 5%. Thermally active carbon nanotubes have already brought to light promising results in PC research and treatment. We report here the construct of a nano-biosystem based on multi-walled carbon nanotubes and polyethylene glycol (PEG)(More)
During the last decade, due to advances in functionalization chemistry, novel nanobiomaterials with applications in tissue engineering and regenerative medicine have been developed. These novel materials with their unique physical and chemical properties are bioactive hierarchical structures that hold great promise for future development of human tissues.(More)
Systemic infections caused by methicillin-resistant Staphylococcus aureus (MRSA) and other bacteria are responsible for millions of deaths worldwide, and much of this mortality is due to the rise of antibiotic-resistant organisms as a result of natural selection. Gold nanoparticles synthesized using the standard wet chemical procedure were photoexcited(More)
Recent data in the literature support the role of nicotinamide (NA) as a pharmacologic agent that stimulates pancreatic beta-cells to produce insulin in vitro. There are data showing that carbon nanotubes may be useful in initiating and maintaining cellular metabolic responses. This study shows that administration of multiwalled carbon nanotubes (MWCNTs)(More)
Severe infections caused by Methicillin-resistant Staphylococcus aureus (MRSA) and other bacteria are responsible for millions of deaths each year. One of the main objectives of future antibiotic strategies is to develop new anti-infective agents, which would be highly effective and drug-resistant (antimicrobial resistance being currently exhibited by(More)
Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women of reproductive age affecting various functions including reproduction and metabolism. This syndrome is associated with increased prevalence of subclinical cardiovascular disease as well as endometrial and ovarian cancer. This syndrome is highly heterogeneous and it is not yet clear(More)
