Migratory birds play a pivotal role in the global dissemination of antimicrobial resistance genes (ARGs), with shorebirds relying on coastal wetlands during their long-distance migrations, environments often contaminated and conducive to ARG transmission. However, systematic investigations into antimicrobial resistance (AMR) in shorebirds remain scarce. During spring and autumn of 2023, we collected 893 throat and cloacal swabs from 480 shorebirds, representing 28 species, at Chongming Dongtan, a critical stopover along the East Asian-Australasian Flyway.

Posaconazole (PSZ), a second-generation triazole antifungal, exhibits broad-spectrum activity but suffers from limited pulmonary concentrations and notable systemic side effects when administered orally or intravenously. This study focuses on optimizing PSZ nanocrystals-agglomerated particles for dry powder inhalers (DPIs) to enhance solubility, dissolution rates, and pulmonary deposition, ultimately improving therapeutic efficacy while minimizing systemic adverse effects.

Previous studies indicated that Parkin, a neurohomeostasis regulatory factor, and NOD-like receptor protein 3 (NLRP3), a core factor driving the inflammatory response, interacted with each other, which affected neuroinflammation occurrence. However, whether rotenone accelerated PD progression via Parkin-NLRP3 loop and the specific mechanisms were still unclear.

With the rapid development of digital research in clinical orthopedics, the efficacy and safety of splint fixation can be better evaluated through biomechanical analysis based on a three-dimensional (3D) finite element model. It is essential to address the current gap in understanding the biomechanical implications of anatomical splint fixation for Colles fractures. By employing advanced 3D finite element analysis, the present study aimed to provide a comprehensive evaluation, offering valuable insights that can contribute to enhancing the effectiveness of anatomical splint fixation in the clinical management of Colles fractures.

We intend to identify the potential hub genes for the development of OSA, which will provide a foundation for the study of the molecular mechanism underlying OSA and for the diagnosis and treatment of OSA. We collected plasma samples from OSA patients and healthy controls for the detection of ceRNA using a chip.
