Estimates of HIV Incidence, Prevalence, and Mortality in China 2018.

A thorough and precise comprehension understanding of the HIV epidemic is crucial for effective HIV prevention and control. This study aimed to update the estimates of the overall HIV burden in China in 2018 and to assess the trends of HIV prevalence, incidence, and mortality from 1985 to 2018. The Estimation and Projection Package (EPP)/Spectrum software was utilized for estimation, a method highly recommended by UNAIDS.

Cerebrospinal Fluid Flow within Ventricles and Subarachnoid Space Evaluated by Velocity Selective Spin Labeling MRI.

This study aims to evaluate cerebrospinal fluid (CSF) flow dynamics within ventricles, and the subarachnoid space (SAS) using the velocity selective spin labeling (VSSL) MRI method with Fourier-transform-based velocity selective inversion preparation. The study included healthy volunteers who underwent MRI scanning with specific VSSL parameters optimized for CSF flow quantification. The VSSL sequence was calibrated against phase-contrast MRI (PC-MRI) to ensure accurate flow velocity measurements.

NRPS-like Gene Contributed to the Biosynthesis of Cyclo(Pro-Val) in a Multistress-Tolerant Aromatic Probiotic, GXDK6.

Cyclo(Pro-Val) is a diketopiperazine (DKP) found widespread in marine microbes and resulting food products. With new bioactivities of cyclo(Pro-Val) being continually discovered, its potential applications in agriculture and food are becoming more evident, highlighting the need for efficient and practical methods to produce these compounds. However, the biosynthesis mechanisms of cyclo(Pro-Val), particularly in probiotics, remain unclear, and the functional identification of nonribosomal peptide synthases (NRPS) is still limited.

STING Activation in Macrophages and Microglia Drives Poststroke Inflammation: Implications for Neuroinflammatory Mechanisms and Therapeutic Interventions.

Background: Monocyte-derived macrophages and microglia initially adopt an anti-inflammatory phenotype following stroke but later transition to a pro-inflammatory state. The mechanisms underlying this phenotypic shift remain unclear. This study investigates the activation dynamics of molecular signaling pathways in macrophages and microglia after stroke.

Survival of People Living with HIV/AIDS from Pre-ART Era to Treat-all Era - China, 1985-2022.

Introduction: A comprehensive analysis of nationwide survival trends for people living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS, PLWHA) from the initial reported case to present has not been conducted. This study evaluated the survival outcomes of PLWHA reported in China from 1985 to 2022.

Methods: We analyzed data from PLWHA recorded in the National HIV/AIDS Comprehensive Response Information Management System from 1985 to 2022.
