Introduction: Stenotrophomonas maltophilia is an opportunistic pathogen associated with various nosocomial infections and is known for its intrinsic multidrug resistance. This study aims to provide a comprehensive overview of the epidemiology and resistance patterns of S. maltophilia in China from 2014 to 2021.

Anti-infective Agent Creation Engineering Research Centre of Sichuan Province, School of Pharmacy, Chengdu University, Chengdu 610106, China.
The first total syntheses of four isoflavone glucosides, tectoridin (), tectoridin A (), tectorigenin 7--β-d-glucopyranosyl-12--β-d-glucopyranoside (), and isotectroigenin 7--β-d-glucopyranoside (), have been accomplished. Key steps in our synthetic approach include a regioselective halogenation reaction, followed by methanolysis to introduce the -OCH group into isoflavone frameworks and a PTC-promoted stereoselective glycosidation to establish glycosidic bonds. The synthesized isoflavone glucosides (-) and their corresponding aglycones ( and ) were evaluated for anti-inflammatory activity against nitric oxide (NO), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1 β (IL-1β) in lipopolysaccharide (LPS)-induced RAW264.

Identifying phage-host interactions (PHIs) is a crucial step in developing phage therapy, which is the promising solution to addressing the issue of antibiotic resistance in superbugs. However, the lifestyle of phages, which strongly depends on their host for life activities, limits their cultivability, making the study of predicting PHIs time-consuming and labor-intensive for traditional wet lab experiments. Although many deep learning (DL) approaches have been applied to PHIs prediction, most DL methods are predominantly based on sequence information, failing to comprehensively model the intricate relationships within PHIs.

Highly efficient photocatalysts for degrading persistent antibiotics and synthetic dye pollutants under visible light are crucial for sustainable environmental remediation. In this study, we engineered a novel BiMoO (BMO)/NiAl-LDH (layered double hydroxide) hybrid catalyst with a unique 2D/2D heterostructure, optimized for the visible-light-driven elimination of ciprofloxacin (CPF) and hazardous synthetic dyes such as rhodamine B and methylene blue. The optimized BMO-30/LDH hybrid demonstrated exceptional photocatalytic performance, achieving nearly complete degradation of CPF and synthetic dyes with high mineralization efficiency, surpassing many previously reported state-of-the-art photocatalysts.

Background: Accurate scientific terminology is crucial in health sciences to avoid misinterpretations. The use of 'artemisinin resistance' to describe delayed parasite clearance may be inaccurately equated with full resistance, as is typically the case when 'resistance' is used with other pathogens, leading to potential confusion. In 2018, the World Health Organization (WHO) introduced 'partial artemisinin resistance' to more accurately reflect the delayed parasite clearance observed with artemisinin-based therapies.
