Obesity is characterized by hyperactivated endocannabinoid System (ECS) in brain and periphery and by increased levels of circulating endocannabinoids (cECs), anandamide (AEA) and 2-arachidonoylglycerol (2AG). It is still debated whether in absence of obesity cECs are only modulated by adiposity or if they are associated with cardiometabolic parameters.We recruited 155 healthy normal weight (NW, BMI: 18.5–24.9 kg/m2) drug-free volunteers ...

The endocannabinoid system is involved in modulating many metabolic and behavioural processes. Due to the instable nature of endocannabinoids in biological fluids and to the poor sensitivity of traditional analytical technologies, little is known about physiological circulating levels of these lipid mediators. We developed and validated an ID-LC-MS/MS method for the simultaneous measurement of four endocannabinoids: anandamide (AEA), 2-arachidonoylglycerol (2-AG), palmitoyl-et...

The development of a reliable and rapid method to simultaneously measure serum steroids represents a compelling challenge for modern endocrinology. Immunoassays are very sensitive methods, being widely employed in automated routine laboratories, lacking, however, in specificity due to cross-reactivity and matrix interference. Gas chromatography–mass spectrometry (GC-MS) constitutes the reference method for quantitative analysis of steroids, but time-consuming sample pre-t...

Ovarian carcinoma (OC) is associated with poor prognosis and low survival rate. Eligible treatment for advanced OC is surgery followed by chemotherapy based on a combination of Platinum and Taxol, but unfortunately long-term outcome of such therapy is disappointing. Moreover, systemic administration of cytotoxic agents is usually accompanied by a series of side effects. On the basis of this evidence, more selective and tumour cell-targeted therapeutic approaches are warranted....
