Remote ischaemic preconditioning increases serum extracellular vesicle concentrations with altered micro-RNA signature in CABG patients.

Acta Anaesthesiol Scand 2018 Dec 11. Epub 2018 Dec 11.

Klinik für Anästhesiologie und Intensivmedizin, Universitätsklinikum Essen, Universität Duisburg-Essen, Essen, Germany.

Background: Remote ischaemic preconditioning (RIPC) can attenuate myocardial ischaemia/reperfusion injury but its underlying mechanisms remain largely unknown. Recently, extracellular vesicles (EVs) containing microRNAs (miRNAs) were shown to mediate distant intercellular communication that may be involved in cardioprotection. We tested the hypothesis that RIPC in anaesthetized patients undergoing coronary artery bypass (CABG) surgery results in the release of EVs from the ischaemic/reperfused arm into the blood stream harbouring cardioprotective miRNAs.

Proteasomal Protein Degradation: Adaptation of Cellular Proteolysis With Impact on Virus-and Cytokine-Mediated Damage of Heart Tissue During Myocarditis.

Front Immunol 2018 28;9:2620. Epub 2018 Nov 28.

Charité-Universitätsmedizin Berlin, Corporate Member of Freie Universität Berlin, Humboldt-Universität zu Berlin, and Berlin Institute of Health (BIH), Institute of Biochemistry, Berlin, Germany.

Viral myocarditis is an inflammation of the heart muscle triggered by direct virus-induced cytolysis and immune response mechanisms with most severe consequences during early childhood. Acute and long-term manifestation of damaged heart tissue and disturbances of cardiac performance involve virus-triggered adverse activation of the immune response and both immunopathology, as well as, autoimmunity account for such immune-destructive processes. It is a matter of ongoing debate to what extent subclinical virus infection contributes to the debilitating sequela of the acute disease. Read More

3D gradient echo snapshot CEST MRI with low power saturation for human studies at 3T.

Magn Reson Med 2018 Nov 15. Epub 2018 Nov 15.

High-field Magnetic Resonance Center, Max Planck Institute for Biological Cybernetics, Tübingen, Germany.

Purpose: For clinical implementation, a chemical exchange saturation transfer (CEST) imaging sequence must be fast, with high signal-to-noise ratio (SNR), 3D coverage, and produce robust contrast. However, spectrally selective CEST contrast requires dense sampling of the Z-spectrum, which increases scan duration. This article proposes a compromise: using a 3D snapshot gradient echo (GRE) readout with optimized CEST presaturation, sampling, and postprocessing, highly resolved Z-spectroscopy at 3T is made possible with 3D coverage at almost no extra time cost.

The early repolarization pattern: Echocardiographic characteristics in elite athletes.

Ann Noninvasive Electrocardiol 2018 Nov 14:e12617. Epub 2018 Nov 14.

Department of Prevention, Rehabilitation and Sports Medicine, Technical University of Munich (TUM), Munich, Germany.

Background: The electrocardiographic early repolarization (ER) pattern is associated with idiopathic ventricular fibrillation and increased long-term cardiovascular mortality. Whether structural cardiac aberrations influence the phenotype is unclear. Since ER is particularly common in athletes, we evaluated its prevalence and investigated predisposing echocardiographic characteristics and cardiopulmonary exercise capacity in a cohort of elite athletes.

Metal-halide perovskites have emerged as highly promising semiconductors with excellent optoelectronic properties. This Perspective outlines how the dynamic response of the ionic lattice affects key electronic properties such as exciton binding energies and charge-carrier mobilities in hybrid perovskites. Such links are shown to derive from the frequency-dependence of the dielectric function, which is governed by contributions from electronic interband transitions, polar vibrations of the metal-halide sublattice, organic cation collective reorientations, and ionic movement.

Distal Dendritic Enrichment of HCN1 Channels in Hippocampal CA1 Is Promoted by Estrogen, but Does Not Require Reelin.

eNeuro 2018 Sep-Oct;5(5). Epub 2018 Oct 15.

Institute of Neuroanatomy, University Medical Center, Hamburg 20246, Germany.

HCN1 compartmentalization in CA1 pyramidal cells, essential for hippocampal information processing, is believed to be controlled by the extracellular matrix protein Reelin. Expression of Reelin, in turn, is stimulated by 17β-estradiol (E2). In this study, we therefore tested whether E2 regulates the compartmentalization of HCN1 in CA1 via Reelin. Read More
