Atomic Imaging of the Surface Termination and Reconstruction of Low and High Index Iridium Oxide Surfaces and Insights into Their Facet-Dependent Oxygen Evolution Activities.
ACS Appl Mater Interfaces

Resolving the atomic surface structure, particularly surface termination or reconstruction, is essential for understanding the catalytic properties of metal oxides. Although rutile phase iridium dioxide (IrO) is the state-of-the-art electrocatalyst for the oxygen evolution reaction (OER) in water splitting, the atomic-level surface structures of IrO remain largely unexplored, limiting our understanding of its facet-dependent OER activities. Herein, we perform aberration-corrected integrated differential phase contrast scanning transmission electron microscopy of the low- and high-index surface structures of spindle-shaped IrO nanorods and reveal distinct surface terminations and/or reconstructions on different surfaces.

Hernia
January 2025
Center for Perioperative Optimization, Department of Surgery, Herlev Hospital, University of Copenhagen, Herlev, Denmark.
Purpose: The AFTERHERNIA Project aims to shift the focus of hernia surgery towards patient-reported outcomes by examining the impact of surgical methods and long-term complications on a national level. Groin and ventral hernia repairs are common surgical procedures with significant impact on patient quality of life and healthcare costs. Most large-scale studies focus on clinical outcomes like reoperation and readmission rates, rather than patient-reported outcomes.

Department of Minimally Invasive Surgery, National University Hospital, Bukit Timah, Singapore.
Background: Given the increasing prevalence of antiplatelet agent use and the lack of high-quality evidence, the CAPTAIN trial aimed to investigate the safety and provide recommendations on continuing acetylsalicylic acid perioperatively in patients undergoing elective laparoscopic totally extraperitoneal inguinal hernia repair (LIHR).
Methods: The CAPTAIN trial was a multicentre, surgeon blind, randomized controlled trial conducted from April 2016 to April 2023. Patients undergoing LIHR were eligible for inclusion.
Microsurgical Repair of Large Nasal Septal Defects: Microsurgical Repair of Large Nasal Septal Defects.
Ann Plast Surg
January 2025
Division of Plastic Surgery, Northwestern University Feinberg School of Medicine, Chicago, IL.
Background: Nasal septal defects cause considerable morbidity and represent a challenging reconstructive problem. Traditional repair techniques have employed local intranasal tissues and allograft adjuncts. For large septal defects (>4-5 cm2), less than half are successfully resolved.

Development
January 2025
Department of Biology, University of Kentucky, Lexington, KY 40506, USA.
Despite being a major target of reconstructive surgery, development of the ear pinna remains poorly studied. Here we provide a cellular characterization of late gestational and postnatal ear pinna development in two rodents and investigate the role of BMP5 in expansion and differentiation of auricular elastic cartilage. We find that ear pinna development is largely conserved between Mus musculus and the highly regenerative Acomys dimidiatus.
