Rubbers prepared from technical poly(butadiene) and natural poly(isoprene) are studied by field-cycling (FC) H NMR relaxometry to elucidate the changes of the relaxation spectrum. Starting with the non-cross-linked polymer successively cross-links are introduced via sulfur or peroxide vulcanization. Applying an advanced home-built relaxometer allows one to probe entanglement dynamics in addition to Rouse dynamics.

Semaglutide, a glucagon-like peptide 1 receptor agonist, has shown promise for weight reduction in obese adults. This study aims to evaluate semaglutide's impact on weight loss, functional status, and clinical outcomes in obese patients with heart failure.

However, research on the relationship between these symptoms and N-terminal pro-brain natriuretic peptide (NT-proBNP), a key biomarker for HF severity and treatment, is scarce and yields inconsistent results.
Aims: This study investigates the relationship among depressive symptomatology, NT-proBNP and health status in a cohort of patients with HF.
Background: The edge-to-edge transcatheter tricuspid valve repair (TTVR) has emerged as a promising technique for the treatment of tricuspid regurgitation (TR). Despite its potential, comparative data on the performance of the novel edge-to-edge devices-MitraClip, PASCAL, and TriClip-remain controversial. In this study, we aim to evaluate the safety and efficacy of these devices in treating TR.
