Non-pharmaceutical infection prevention measures in nosocomial SARS-CoV-2 outbreaks: a retrospective multi-centre cohort study.

Background: Hospital severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreaks are relevant for patients and healthcare systems within and beyond the pandemic.

Aim: To explore the characteristics of SARS-CoV-2 outbreaks and their infection prevention and control (IPC) measures during the different pandemic waves.

Methods: A comprehensive structured template for SARS-CoV-2 outbreaks was developed and filled out by six university hospitals.

Voluntarily stopping eating and drinking (VSED): A systematic mixed-methods review focusing on the carers' experiences.

Background: Voluntary stopping of eating and drinking (VSED) is a way to end one's life prematurely. We synthesized the empirical data on VSED.

Methods: In this systematic mixed-methods review, we searched MEDLINE, CINAHL, PsycINFO, Google Scholar, and BELIT for English and German articles published between January 1, 2013 and November 12, 2021.

Generation of a heterozygous Calsequestrin 2 F189L iPSC line (UMGi158-B) by CRISPR/Cas9 genome editing to investigate the cardiac pathophysiology of Takotsubo Syndrome and Catecholaminergic Polymorphic Ventricular Tachycardia.

Takotsubo Syndrome (TTS) is a potentially life-threatening disease characterized by a transient left ventricular apical akinesia in response to β-adrenergic overstimulation. Since a genetic predisposition is assumed, we generated an iPSC-line carrying a p.F189L mutation in the calcium buffering protein Calsequestrin 2 (CasQ2).

The influence of polyacrylamide gel substrate elasticity on primary cultures of rat retinal ganglion cells.

In vitro primary cell culture models of retinal ganglion cells (RGC) are widely used to study pathomechanisms of diseases such as glaucoma. The biomechanic interaction with the culture substrate is known to influence core cellular functions. RGC cultures, however, are usually grown on rigid plastic or glass substrates.

Metallaelectro-catalyzed alkyne annulations C-H activations for sustainable heterocycle syntheses.

Alkyne annulation represents a versatile and powerful strategy for the assembly of structurally complex compounds. Recent advances successfully enabled electrocatalytic alkyne annulations, significantly expanding the potential applications of this promising technique towards sustainable synthesis. The metallaelectro-catalyzed C-H activation/annulation stands out as a highly efficient approach that leverages electricity, combining the benefits of electrosynthesis with the power of transition-metal catalyzed C-H activation.

Structural-functional connectomics in major depressive disorder following aiTBS treatment.

Major depressive disorder (MDD) has been associated with changes in the structural (SC) and functional connectivity (FC) of the brain. This study investigated the effects of accelerated intermittent theta burst stimulation (aiTBS) on SC-FC coupling and graph theory measures, focusing on the association between baseline SC-FC coupling of the dorsolateral prefrontal cortex (dlPFC) and clinical improvement. In a randomized, sham-controlled, quadruple-blind, crossover study, aiTBS was delivered to the left dlPFC of depressed patients with MDD, and diffusion tensor imaging (DTI) and resting-state functional magnetic resonance imaging (rsfMRI) data were acquired.

Digitalomics - digital transformation leading to omics insights.

Introduction: Biomarker discovery is increasingly moving from single omics to multiomics, as well as from multi-cell omics to single-cell omics. These transitions have increasingly adopted digital transformation technologies to accelerate the progression from data to insight. Here, we will discuss the concept of 'digitalomics' and how digital transformation directly impacts biomarker discovery.

Quantitative modeling of signaling in aggressive B cell lymphoma unveils conserved core network.

B cell receptor (BCR) signaling is required for the survival and maturation of B cells and is deregulated in B cell lymphomas. While proximal BCR signaling is well studied, little is known about the crosstalk of downstream effector pathways, and a comprehensive quantitative network analysis of BCR signaling is missing. Here, we semi-quantitatively modelled BCR signaling in Burkitt lymphoma (BL) cells using systematically perturbed phosphorylation data of BL-2 and BL-41 cells.

Cellular and extracellular proteomic profiling of paradoxical low-flow low-gradient aortic stenosis myocardium.

Aims: Patients with severe aortic stenosis (AS), low transvalvular flow (LF) and low gradient (LG) with normal ejection fraction (EF)-are referred to as paradoxical LF-LG AS (PLF-LG). PLF-LG patients develop more advanced heart failure symptoms and have a worse prognosis than patients with normal EF and high-gradient AS (NEF-HG). Despite its clinical relevance, the mechanisms underlying PLF-LG are still poorly understood.

Plant terrestrialization: an environmental pull on the evolution of multi-sourced streptophyte phenolics.

Phenolic compounds of land plants are varied: they are chemodiverse, are sourced from different biosynthetic routes and fulfil a broad spectrum of functions that range from signalling phytohormones, to protective shields against stressors, to structural compounds. Their action defines the biology of land plants as we know it. Often, their roles are tied to environmental responses that, however, impacted already the algal progenitors of land plants, streptophyte algae.

Evolution of plant metabolism: the state-of-the-art.

Immense chemical diversity is one of the hallmark features of plants. This chemo-diversity is mainly underpinned by a highly complex and biodiverse biochemical machinery. Plant metabolic enzymes originated and were inherited from their eukaryotic and prokaryotic ancestors and further diversified by the unprecedentedly high rates of gene duplication and functionalization experienced in land plants.

Biotic interactions, evolutionary forces and the pan-plant specialized metabolism.

Plant specialized metabolism has a complex evolutionary history. Some aspects are conserved across the green lineage, but many metabolites are unique to certain lineages. The network of specialized metabolism continuously diversified, simplified or reshaped during the evolution of streptophytes.

Conserved carotenoid pigmentation in reproductive organs of Charophyceae.

Sexual reproduction in Charophyceae abounds in complex traits. Their gametangia develop as intricate structures, with oogonia spirally surrounded by envelope cells and richly pigmented antheridia. The red-probably protectant-pigmentation of antheridia is conserved across Charophyceae.
