Cue-reactivity to distal cues in individuals at risk for gaming disorder.

Background: Gaming disorder (GD) is a disorder due to addictive behaviors (ICD-11). Cue-reactivity and craving are relevant mechanisms in the development and maintenance of addictive behaviors. When confronted with cues showing in-game content (proximal cues) individuals with higher symptom severity show increased cue-reactivity.

Changes in dynamic mitral valve geometry during percutaneous edge-edge mitral valve repair with the MitraClip system.

Background: The aim of this study was to quantify the acute dynamic changes of mitral valve (MV) geometry throughout the cardiac cycle-during percutaneous MV repair with the MitraClip system by 3-dimensional transesophageal echocardiography (3D TEE).

Methods: The MV was imaged throughout the cardiac cycle (CC) before and after the MitraClip procedure using 3D TEE in 28 patients (mean age, 77 ± 8 years) with functional mitral regurgitation (FMR). Dynamic changes in the MV annulus geometry and anatomical MV orifice area (AMVOA) were quantified using a novel semi-automated software.

Length dependence for intramolecular energy transfer in three- and four-color donor-spacer-acceptor arrays.

A series of donor-spacer-acceptor triads has been synthesized and fully characterized. Both donor and acceptor units are built from boron dipyrromethene (BODIPY) dyes but they differ in their respective conjugation lengths, and thereby offer quite disparate optical properties. The spacer units comprise an oligomer of 1,4-phenylene-diethynylene repeat units and allow the boron-boron separation distance to be varied progressively from 18 to 38 A.

Electronic energy transfer to the S2 level of the acceptor in functionalised boron dipyrromethene dyes.

Taking the high road: Highly efficient electronic energy transfer takes place from a set of appended aryl polycyclic hydrocarbons to an expanded boron dipyrromethene (Bodipy)-based dye (see figure) despite negligible spectral overlap with the lowest-energy excited state localised on the acceptor.A multi-component array has been constructed around an expanded boron dipyrromethene (Bodipy) dye that absorbs and emits in the far-red region. One of the appendages is a perylene-based moiety that is connected to the boron atom of the terminal Bodipy by a 1,4-diethynylphenylene connector.
