Novel Sulfur‐Containing Polyurethanes using 5‐(Chloromethyl)Furfural as a Renewable Building Block

ChemSusChem, Volume 18, Issue 18, September 23, 2025.
A novel methodology is presented for synthesizing biomass‐derived diols using 5‐(chloromethyl)furfural, thiols, and mild reaction conditions. These innovative diols are subsequently utilized in the production of new polyurethanes via polyaddition with both commercially available and biomass‐derived diisocyanates.

What characterizes device‐related thrombosis following LAAC, if ejection fraction fails to shine?

Echocardiography
AbstractCardiac compartmental size depends on sex, with smaller values found in (healthy) women compared to a matched group of men. Various types of heart disease may cause dilation of the affected chamber. For example, atrial fibrillation (AF) is associated with enlarged left atrial (LA) size, often also implying increased left ventricular (LV) size ...

Stroke prevention in nonvalvular atrial fibrillation: Thoracoscopic left atrial appendage closure with or without surgical ablationCentral MessagePerspective

JTCVS Techniques
Objectives: Totally thoracoscopic left atrial appendage closure (TT-LAAC) with or without the MAZE procedure is an LAA management technique that prevents cardioembolic events by closing the LAA in patients with atrial fibrillation (AF).

Hypotensive Effect After Left Atrial Appendage Clipping in Patients With Atrial Fibrillation: The Role of B-Type Natriuretic Peptide

The Heart Surgery Forum
Background: Atrial fibrillation (AF) is associated with an increased risk of thromboembolism, primarily due to thrombus formation in the left atrial appendage (LAA).

Left atrial appendage closure in patients with atrial fibrillation and acute ischaemic stroke despite anticoagulation

Stroke and Vascular Neurology
Background The occurrence of acute ischaemic stroke (AIS) while using oral anticoagulants (OAC) is an increasingly recognised problem among nonvalvular atrial fibrillation (NVAF) patients. We aimed to elucidate the potential role of left atrial appendage
