Atrioventricular conduction disorders in aortic valve infective endocarditis.

Background: Aortic valve infective endocarditis may be complicated by high-degree atrioventricular block in up to 10-20% of cases.

Aim: To assess high-degree atrioventricular block occurrence, contributing factors, prognosis and evolution in patients referred for aortic infective endocarditis.

Methods: Two hundred and five patients referred for aortic valve infective endocarditis between January 2018 and March 2021 were included in this study.

Untargeted Metabolomics Approach Using UHPLC-HRMS to Unravel the Impact of Fermentation on Color and Phenolic Composition of Rosé Wines.

Color is a major quality trait of rosé wines due to their packaging in clear glass bottles. This color is due to the presence of phenolic pigments extracted from grapes to wines and products of reactions taking place during the wine-making process. This study focuses on changes occurring during the alcoholic fermentation of Syrah, Grenache and Cinsault musts, which were conducted at laboratory (250 mL) and pilot (100 L) scales.

Unravelling copper effect on the production of varietal thiols during Colombard and Gros Manseng grape juices fermentation by .

Nowadays the rapidly increasing organic vineyard management with the utilization of copper as sole fungal control pesticide against downy mildew raises once again the question of copper impact on varietal thiols in wine. For this purpose, Colombard and Gros Manseng grape juices were fermented under different copper levels (from 0.2 to 3.
