The present study investigated the water quality index, microbial composition and antimicrobial resistance genes in urban water habitats. Combined chemicals testing, metagenomic analyses and qualitative PCR (qPCR) were conducted on 20 locations, including rivers from hospital surrounds ( = 7), community surrounds ( = 7), and natural wetlands ( = 6). Results showed that the indexes of total nitrogen, phosphorus, and ammonia nitrogen of hospital waters were 2-3 folds high than that of water from wetlands.

Design: A retrospective cohort study.
Setting And Participants: A total of 2232 patients with IGA who came from the Surveillance, Epidemiology, and End Results database.
Purpose: We analyzed the clinical concordance of mNGS test results from blood samples and improved the clinical efficiency of mNGS in the diagnosis of suspected sepsis pathogens.
Patients And Methods: In this study, 99 samples of suspected blood flow infection were included for plasma mNGS, and the correlation between mNGS results and blood culture results, serum inflammatory indices, clinical symptoms and antibiotic treatment was analyzed, as well as the comparison with the detection rate of BALF pathogens, as well as the classification of different pathogens in the mNGS results were analyzed.
Results: The mNGS pathogen detection rate was higher than that of traditional blood culture (83.
Article Synopsis
- The study investigates the arrangement of polymer chains in blend films made from polystyrene (PS), deuterated polystyrene (dPS), and poly(methyl methacrylate) (PMMA) under specific conditions.
- It finds that by adjusting the blend composition and annealing temperature, the films primarily form layers with dPS preferentially located at surfaces and within PS layers at 230 °C.
- At 270 °C, dPS still prefers to be near the surfaces in thin films, but this surface segregation is not observed in thicker films.
We have demonstrated the phase behavior of substrate-supported films of a symmetric weakly segregated polystyrene--poly (methyl methacrylate), P(S--MMA), block copolymer and its blends with homopolymer polystyrene (PS) at different compositions. Upon increasing the content of added PS in the blends, lamellae (L), perforated layers (PL), double gyroid (DG) and cylinders (C) are obtained in sequence for films. Among these nanodomains, PL and DG only exist in a narrow region ( denotes the volume fraction of PS).

- The study investigates how osmotic pressure affects the nanostructures in thin films of a specific block copolymer (P(S-b-MMA)) and its mixtures with polystyrene (PS) homopolymer under different compositions.
- Thin films were created using a method called surface neutralization, where PS mats were treated with UV light and then thermally annealed, leading to the formation of various layer structures, including perpendicular lamellae.
- The removal of the PMMA block through UV exposure and acetic acid rinsing caused osmotic pressure, resulting in surface wrinkling, which was influenced by factors such as film thickness, PS content, and the molecular weight of the block copolymer used.
Objective: To assess the efficacy and safety of double J (DJ) stented, external stented and stent-less procedures in pediatric pyeloplasty by adopting a network meta-analysis (NMA).
Material And Methods: Electronic databases including PubMed, Cochrane Library, Web of science and Embase database were retrieved. The trials that compared double J (DJ) stented, external stented or stent-less procedures in pediatric pyeloplasty were identified.
