Distribution and Antibiotic Resistance Analysis of 13,048 Clinically Common Isolates.

Objective: This study investigated the distribution and antibiotic resistance profiles of common bacteria isolated from clinical specimens at a hospital's microbiology laboratory between 2020 and 2022.

Methods: A retrospective analysis was conducted on microbial culture results from clinical specimens collected over three years, including sample types, departmental distribution, pathogen species, and resistance profiles.

Results: A total of 13,048 unique pathogenic strains were isolated, predominantly from respiratory and urine specimens.

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.

Aflatoxin B1 Exposure Suppresses the Migration of Dendritic Cells by Reshaping the Cytoskeleton.

Exposure to Aflatoxin B1 (AFB1) is considered a significant risk factor for human diseases, including the immune function impairment of immune cells. Dendritic cells (DCs), as essential antigen-presenting cells, play a pivotal role in bridging innate and adaptive immunity. However, the impact of AFB1 exposure on DCs has not been fully elucidated.
