Safety and complications associated with the use of protamine in percutaneous coronary intervention.

Objectives: There is a paucity of data on the use of protamine after PCI. The purpose of this study was to assess the incidence of thrombotic complications of protamine after high-risk PCI.

Methods: The authors conducted a retrospective analysis of 168 patients.

Characterization of an MR-compatible motion platform for quality assurance of motion-compensated treatments on the 1.5 T MR-linac.

Background: Novel motion-compensated treatment techniques on the MR-linac can address adverse intra-fraction motion effects. These techniques involve beam gating or intra-fraction adaptations of the treatment plan based on real-time magnetic resonance imaging (MRI) performed during treatment. For quality assurance (QA) of these workflows, a multi-purpose motion platform is desirable.

Remodelling of Rea1 linker domain drives the removal of assembly factors from pre-ribosomal particles.

The ribosome maturation factor Rea1 (or Midasin) catalyses the removal of assembly factors from large ribosomal subunit precursors and promotes their export from the nucleus to the cytosol. Rea1 consists of nearly 5000 amino-acid residues and belongs to the AAA+ protein family. It consists of a ring of six AAA+ domains from which the ≈1700 amino-acid residue linker emerges that is subdivided into stem, middle and top domains.

Hemodynamic Effects and Clinical Outcomes of Left Atrial Veno-Arterial Extracorporeal Membrane Oxygenation (LAVA-ECMO) in Cardiogenic Shock.

Left atrial veno-arterial extracorporeal membrane oxygenation (LAVA-ECMO) in cardiogenic shock (CS) is a novel mechanical cardiocirculatory support strategy that provides robust cardiocirculatory support and simultaneous left and right atrial venting by way of a multifenestrated transeptal catheter. We performed a single-center retrospective analysis of all patients aged ≥18 years with CS who underwent LAVA-ECMO at a quaternary care institution from 2018 to 2023. Clinical outcomes and prehemodynamics and posthemodynamics were evaluated.
