It is generally believed that the low-frequency variability of climatic parameters seems to be connected to solar cycles. The principal periodicities are: 11-year (Schwabe), 22-year (Hale), 33-year (Bruckner) and 80–100year (Gleissberg) cycles. The main heliophysical factors acting on climate, the biosphere and the atmosphere are solar irradiance, the intensity of solar and galactic cosmic rays...

A number of studies have demonstrated a protective effect associated with N-acetyl-l-cysteine (NAC) against toxic chemical exposure. However, the impact of long-term oral dosing on tissue pathology has not been determined. In this study, the authors assessed the impact of long-term oral NAC administration on organ histopathology and tissue glutathione (GSH) and total glutathione-S-transferase (...

The extraction of technetium species at oxidation state lower than +7 has been examined in sulfuric and sulfuric/nitric acid solutions using UV-Vis spectroscopy and optically transparent thin layer cell (RVC-OTTLE). Soluble Tc(III), TcO2+ and [Tc2O2]3+ species with absorption bands at 420-450, 400, and 502 nm, respectively, were detected as products of pertechnetates electroreduction. The distr...

Objectives To depict: a) the clinical phenotype, the genotype-phenotype interplay and b) the response to treatment and the long-term outcome in a large series of Greek FMF pts. Patients and methods: Seventy children (46 females) with established FMF according to Tel Hashomer classification criteria were enrolled in this retrospective study. Pts were followed-up over a 30-year period (1986-2015)...
