Bio-inspired chitosan/polydopamine-nanoparticle based sorbent bead: A versatile platform for separation and HPLC analysis of tetracycline antibiotics from various sample matrix.

This study introduces an innovative bio-based sorbent bead crafted by integrating chitosan (CS) biopolymers, Fe(NO3)3 and polydopamine nanoparticles (PDA NPs) via glutaraldehyde crosslinking. The primary focus of this study was the concurrent separation of diverse tetracycline antibiotics (TCs), followed by rigorous reversed-phase liquid chromatography analysis. The fabricated CS/Fe@PDA sorbent beads were comprehensively characterized using scanning electron microscopy and energy-dispersive X-ray spectroscopy, revealing a surface rich in active carbon (C), nitrogen (N), and oxygen (O) moieties.

Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Aquaporin‑1 regulates microglial polarization and inflammatory response in traumatic brain injury.

The present study investigated the mechanisms by which aquaporin 1 (AQP1) influences microglial polarization and neuroinflammatory processes in traumatic brain injury (TBI). A model of TBI was generated in AQP1‑knockout mice to assess the impact of AQP1 deletion on inflammatory cytokine release, neuronal damage and cognitive function. Immunofluorescence, reverse transcription‑quantitative PCR, western blotting and enzyme‑linked immunosorbent assay were employed to evaluate pro‑inflammatory and anti‑inflammatory markers.

Impact of diagnosis-related group payment on medical expenditure and treatment efficiency on people with drug-resistant tuberculosis: a quasi-experimental study design.

Background: The severe health challenge and financial burden of drug-resistant tuberculosis (DR-TB) continues to be an impediment in China and worldwide. This study aimed to explore the impact of Diagnosis-related group (DRG) payment on medical expenditure and treatment efficiency among DR-TB patients.

Methods: This retrospective cohort study included all DR-TB patients from the digitized Hospital Information System (HIS) of Wuhan Pulmonary Hospital and the TB Information Management System (TBIMS) with completed full course of National Tuberculosis Program (NTP) standard treatment in Wuhan from January 2016 to December 2022, excluding patients whose treatment spanned both before and after the DRG timepoint.

Incidence and outcome of hepatitis D virus infection in people with HIV in the era of tenofovir-containing antiretroviral therapy.

Background: Tenofovir-containing antiretroviral therapy (ART) improves survival in HBV-coinfected people with HIV (PWH). We investigated the incidence of HDV infection and its clinical impact in HBV-coinfected PWH in the era of tenofovir-containing ART.

Methods: Between 2011 and 2022, HBV-coinfected PWH were included and followed until December 2023.
