Barlow disease: effect of mitral valve repair on ventricular arrhythmias in 82 patients in a retrospective long-term study.

Background: Patients (pt) with mitral valve prolapse (MVP) due to Barlow disase (BD) have an increased incidence of ventricular arrhythmias (VA; including ventricular tachycardias VT) and sudden cardiac death (SCD). Data on the effect of MV repair on VA are scarce.

Methods: Pre- and postoperative VA in severe mitral regurgitation (MR) with MVP due to BD undergoing surgical mitral valve repair were analyzed.

Marfan syndrome and related connective tissue disorders in the current era in Switzerland in 103 patients: medical and surgical management and impact of genetic testing.

Introduction: Marfan syndrome (MFS) and related connective tissue disorders (CTDs) are increasingly recognised. Genetic testing has greatly improved the diagnostic outcome/power over the last two decades. In this study we describe a multicentre cohort of adults with MFS and related CTDs, with a particular focus on results from genetic testing.

Capillary rise of superspreaders.

Trisiloxane surfactants, known as 'superspreaders', are commonly employed in numerous applications where enhanced wetting is of the utmost importance. The underlying mechanisms of superspreader wetting have been a focus of scientific interest for ca. 2 decades, and a number of mechanisms have been proposed to explain the unique trisiloxane dynamics.

On the effect of pH on spreading of surfactant solutions on hydrophobic surfaces.

Surfactants are invaluable in a number of agricultural applications in products such as pesticides and herbicides. In these products, surfactants are very often used in conjunction with acidifiers in order to improve their half-life. In this paper, we investigate how the change in pH affects surfactant wetting and spreading.
