Octaethyl vs Tetrabenzo Functionalized Ru Porphyrins on Ag(111): Molecular Conformation, Self-Assembly and Electronic Structure.

Metalloporphyrins on interfaces offer a rich playground for functional materials and hence have been subjected to intense scrutiny over the past decades. As the same porphyrin macrocycle on the same surface may exhibit vastly different physicochemical properties depending on the metal center and its substituents, it is vital to have a thorough structural and chemical characterization of such systems. Here, we explore the distinctions arising from coverage and macrocycle substituents on the closely related ruthenium octaethyl porphyrin and ruthenium tetrabenzo porphyrin on Ag(111).

Validation of gender-equity model for liver allocation (GEMA) and its sodium variant (GEMA-Na) in candidates for liver transplantation.

Background: The current allocation system for liver transplantation (LT) is based on the sickest-first policy, using objective variables to ensure equal priority. However, under-prioritization of female patients for LT, compared to males, is well demonstrated and new scores have been proposed to overcome this systematic bias. This study evaluated the ability of these new scores to predict the long-term outcomes of patients with cirrhosis.

A Simple Way to Exclude a Lethal Complication Following Atrial Fibrillation Radiofrequency Ablation: A Case Report.

Esophageal injury is a serious complication following atrial fibrillation catheter ablation procedures. It may manifest as atrio-esophageal fistula, pericardio-esophageal fistula (PEF), or restricted perforation, with high mortality rate if left unoperated. Chest computed tomography with intravenous contrast is the mainstay of diagnosis; however, a definite imaging diagnosis is often delayed and may worsen patient outcomes.

Distal radial artery palpability and successful arterial access for coronary angiography: A post-hoc analysis from two randomized trials.

Background: Distal radial artery access (DRA) has been emerged as an alternative for conventional transradial arterial access. While palpation of radial artery is mandatory prior coronary angiography, it remains unknown the clinical impact of palpation in DRA success. Aim of our study is to explore whether the palpability of distal radial artery is linked with higher rates of successful arterial access.
