Stable radicals have attracted increasing attention in recent years because of their unique electronic and optical characteristics. Aminoxyl radicals are one of the most widely studied stable radicals to date, but their applications in opto-functional materials have yet to be explored in detail. Our group previously reported the boron complexes of aminoxyl radicals exhibit near-infrared (NIR) absorption.

While Vericiguat is considered one of the standard treatments for heart failure, it is unclear under which conditions Vericiguat would be most effective. With a focus on the prognosis and improved EF of heart failure, we aimed to investigate in which cases Vericiguat is suitable for use in addition to standard cardioprotective drugs.

- The study visualizes the electron-density distribution in the 1,2-digermacyclobutadiene ring, highlighting its unique electron behavior.
- The GeC ring exhibits a strong Möbius 4π-electron aromatic character, which is distinct from the antiaromatic nature of the all-carbon cyclobutadiene.
- This research suggests that the presence of germanium alters the electronic properties significantly compared to the carbon-only structure.
Objectives: This study aimed to evaluate the surgical outcomes of composite-valve root replacement with bioprosthesis (b-CVRR) after acute type A aortic dissection (AAAD) repair.
Methods: We included 41 patients who underwent b-CVRR after surgery for AAAD from 2007 to 2022. We excluded seven patients with VSRR, three with mechanical valve use, one with mycotic aneurysm, and one with cardiopulmonary resuscitation.
Introduction: Intensive care unit risk stratification models have been utilized in elective joint arthroplasty; however, hip fracture patients are fundamentally different in their clinical course. Having a critical care risk calculator utilizing pre-operative risk factors can improve resourcing for hip fracture patients in the peri‑operative period.
Methods: A cohort of geriatric hip fracture patients at a single institution were reviewed over a three-year period.
