Bacteraemia after transcatheter aortic valve implantation: a nationwide cohort study.

Background: Bacteraemia and infective endocarditis (IE) are rare but severe complications of transcatheter aortic valve implantation (TAVI). Limited data exist on the incidence and microbiological profile of early bacteraemia in this population. This study aimed to evaluate the 6-month incidence of bacteraemia, IE and associated mortality following TAVI.

Room-Temperature Deposition of δ-NiGa Thin Films and Nanoparticles via Magnetron Sputtering.

Magnetron sputtering is a versatile method for investigating model system catalysts thanks to its simplicity, reproducibility, and chemical-free synthesis process. It has recently emerged as a promising technique for synthesizing δ-NiGa thin films. Physically deposited thin films have significant potential to clarify certain aspects of catalysts by eliminating parameters such as particle size dependence, metal-support interactions, and the presence of surface ligands.

Improved recombinant expression of soluble cathepsin B and L in Escherichia coli.

Cysteine cathepsins such as cathepsin B and L play an important role in numerous diseases like acute pancreatitis or SARS-CoV-2 and therefore have high potential for the development of new therapeutics. To be able to screen for potent and selective inhibitors sufficient amounts of protein are required. Here, we present an easy and efficient protocol for the recombinant expression of soluble and active murine cathepsin B and L.

Feasibility and accuracy of DireCt Lung Ultrasound Evaluation technique to monitor extravascular lung water in porcine lungs.

Objectives: Extravascular lung water precedes deterioration of pulmonary function. Current tools to assess extravascular lung water in a setting of donor lung procurement and ex vivo lung perfusion (EVLP) are either subjective or not feasible. Therefore, a direCt Lung Ultrasound Evaluation (CLUE) has been introduced.

Label-free single-cell RNA multiplexing leveraging genetic variability.

Single cell RNA sequencing has provided unprecedented insights into the molecular cues and cellular heterogeneity underlying human disease. However, the high costs and complexity of single cell methods remain a major obstacle for generating large-scale human cohorts. Here, we compare current state-of-the-art single cell multiplexing technologies, and provide a widely applicable demultiplexing method, SoupLadle, that enables simple, yet robust high-throughput multiplexing leveraging genetic variability of patients.
