A Renal Artery Stenting Case: Support for Increased Use of Drug-Eluting Stents.

Fibromuscular dysplasia is a rare, systemic arteriovascular disease that often affects the renal arteries. Balloon angioplasty is recommended for uncontrolled hypertension and compromised renal function; stenting is a bailout option. Drug-eluting stents have been suggested in case reports.

Efficacy and safety of ECG-synchronized pulsatile extracorporeal membrane oxygenation in the clinical setting: The SynCor Trial.

Introduction: Mechanical circulatory support (MCS) devices are increasingly used as a treatment option in resuscitation or in patients with cardiogenic shock (CS). Prophylactic implantation in high-risk percutaneous coronary interventions (HRPCI) is another upcoming indication. The i-cor ECG-synchronized cardiac assist device combines the hemodynamic support of a veno-arterial extracorporeal membrane oxygenation (VA-ECMO) with the ability to generate a pulsatile flow and thus decreasing adverse effects of VA-ECMO on myocardial function.

Longitudinal Study of the Signal Strength in two Serologic Assays for Detection of SARS-CoV-2 Specific Antibodies.

Background: In the course of the current SARS-CoV-2 pandemic, antibody assays provide an important means for guidance of public health efforts. Thus, characterization of the course of antibody signals on different widely used assays is needed.

Methods: We selected 25 PCR-confirmed SARS-CoV-2 cases among 3,273 healthcare workers and measured the course of the antibody signal using the Abbott Architect SARS-CoV-2 IgG assay and the Roche Elecsys® Anti-SARS-CoV-2 immunoassay.

Distal Transradial Access for Coronary Angiography and Interventions in Everyday Practice: Data From the TRIANGLE Registry (TwitteR Initiated registry for coronary ANgiography in Germany via distaL radial accEss).

Introduction: Transradial access (TRA) has become the primary route for coronary angiography (CAG) and percutaneous coronary interventions (PCI). Recently a new puncture site more distally in the area of the anatomical snuffbox has been described. With this multicenter registry, we wish to demonstrate the feasibility and safety of the distal radial access (dRA).

On-Surface Annulation Reaction Cascade for the Selective Synthesis of Diindenopyrene.

We investigated the thermally induced on-surface cyclization of 4,10-bis(2'-bromo-4'-methylphenyl)-1,3-dimethylpyrene to form the previously unknown, nonalternant polyaromatic hydrocarbon diindeno[1,2,3-cd:1',2',3'-mn]pyrene on Au(111) using scanning tunneling microscopy and spectroscopy. The observed unimolecular reaction involves thermally induced debromination followed by selective ring closure to fuse the neighboring benzene moieties via a five-membered ring. The structure of the product has been verified experimentally as well as theoretically.
