Postflight Pulmonary Barotrauma in a Pilot Without Underlying Disease.

Background: Exposure to pressure changes can result in barotrauma in gas-filled cavities when volume expansion exceeds tissue strength, leading to local disruption. While few cases have been reported, we present a case of pulmonary barotrauma developed postflight in a pilot without underlying disease, and the most likely reason is improper pressure-breathing in flight.

Case Report: A 25-yr-old healthy male fighter pilot experienced slight chest pain 3 h after a 1-h flight training mission, during which the peak G was 6 G.

Interwoven MnO/Co-derived N-doped carbon nanotube composites as highly efficient and durable bifunctional oxygen catalysts for zinc-air batteries.

Rechargeable zinc-air batteries (ZABs) have emerged as a compelling candidate for advanced electrochemical energy storage and conversion systems, owing to their exceptional theoretical energy density, cost-effectiveness, and environmental compatibility. Despite these advantages, their practical utility is restrained by the intrinsically sluggish kinetics of both the oxygen reduction (ORR) and oxygen evolution (OER) reactions. Herein, we present a novel coordination-assisted ball-milling approach to fabricate MnO/Co-N-CNT composites featuring a unique interwoven carbon nanotube architecture.

A Milligan-Morgan hemorrhoidectomy (MMH) is the most frequently applied surgical technique due to its clear efficacy and high success rate, but the reported postoperative complications remain a major problem. This study aimed to retrospectively evaluate the efficacy and safety of a MMH combined with rubber band ligation and polidocanol foam sclerotherapy (MMH + RBL + PFS) for the management of grade III/IV hemorrhoids.

Quantum Dots Mediated Crystallization Enhancement in Two-Step Processed Perovskite Solar Cells.

Hybrid organic-inorganic lead halide perovskites have emerged as a promising material for high-efficiency solar cells, yet challenges related to crystallization and defects limit their performance and stability. This study investigates the use of perovskite quantum dots (QDs) as crystallization seeds to enhance the quality of FAPbI perovskite films and improve the performance of perovskite solar cells (PSCs). We demonstrate that CsPbI and CsPbBr QDs effectively guide the crystallization process, leading to the formation of larger crystals with preferential orientations, particularly the (001) and (002) planes, which are associated with reduced defect densities.

Mecp2 fine-tunes quiescence exit by targeting nuclear receptors.

Quiescence (G0) maintenance and exit are crucial for tissue homeostasis and regeneration in mammals. Here, we show that methyl-CpG binding protein 2 (Mecp2) expression is cell cycle-dependent and negatively regulates quiescence exit in cultured cells and in an injury-induced liver regeneration mouse model. Specifically, acute reduction of Mecp2 is required for efficient quiescence exit as deletion of Mecp2 accelerates, while overexpression of Mecp2 delays quiescence exit, and forced expression of Mecp2 after Mecp2 conditional knockout rescues cell cycle reentry.
