Molecular relaxations in magnesium polymer electrolytes via GHz broadband electrical spectroscopy.

GHz broadband electrical spectroscopy (G-BES) is adopted to investigate the molecular relaxations and interactions occurring within the system in an oxygen- and water-free atmosphere in the 300 kHz-20 GHz and -40 to 250 °C frequency and temperature ranges, respectively. A new electrolyte for magnesium secondary batteries that can transfer magnesium ions efficiently is presented. This electrolyte is based on polyethylene glycol 400 and a polymeric form of δ-MgCl2 .

Persistent increase of osteoprotegerin levels after cortisol normalization in patients with Cushing's syndrome.

Objective: Osteoprotegerin (OPG) has been identified as a decoy receptor that inhibits osteoclast differentiation and, more recently, as a paracrine regulator of vascular calcification. OPG is suppressed by glucocorticoids (GC); however, results from experimental and clinical studies are not univocal. The aim of this study was to evaluate OPG and bone metabolism in patients with Cushing's syndrome (CS) before and after cure.

[A proposal of a triage model to control spreading diseases in public health].

Each case of infectious disease can be considered the consequence of an unexpected event which started an infection chain. Every infectious case is therefore a potential source of epidemic, resulting from the total of the epidemic potential of each individual variable involved in the pathology spreading process. This article identifies the main variables involved in the spreading of infectious diseases in communities, and it develops a method which gives importance to each one of them based on the main control measures available to Public Health operators.
