Acute lung injury (ALI) is a severe complication of sepsis, and its underlying pathological mechanisms remain poorly understood. This study aims to investigate the role and mechanisms by which IRGM mediates autophagy through the regulation of the AKT/mTOR signaling pathway in sepsis-induced ALI. Initially, a sepsis-induced ALI mouse model was established using cecal ligation and puncture (CLP).

Gastrulation marks a pivotal stage in mammalian embryonic development, establishing the three germ layers and body axis through lineage diversification and morphogenetic movements. However, studying human gastrulating embryos is challenging due to limited access to early tissues. Here we show the use of spatial transcriptomics to analyse a fully intact Carnegie stage 7 human embryo at single-cell resolution, along with immunofluorescence validations in a second embryo.

Background: Sepsis is a life-threatening condition characterized by organ dysfunction due to an impaired immune response to infection. The lungs are highly susceptible to infection, often resulting in acute lung injury (ALI). The immune-related GTPase M (IRGM) and its murine homolog Irgm1 mediate autophagy and are implicated in inflammatory diseases, yet their roles in sepsis-induced ALI remain unclear.

Progress in understanding early human development has been impeded by the scarcity of reference datasets from natural embryos, particularly those with spatial information during crucial stages like gastrulation. We conducted high-resolution spatial transcriptomics profiling on 38,562 spots from 62 transverse sections of an intact Carnegie stage (CS) 8 human embryo. From this spatial transcriptomic dataset, we constructed a 3D model of the CS8 embryo, in which a range of cell subtypes are identified, based on gene expression patterns and positional register, along the anterior-posterior, medial-lateral, and dorsal-ventral axis in the embryo.

Objectives: To determine whether the age at menarche (AAM) and the age at menopause (ANM) are causally related to the development of sepsis.

Methods: We performed a two-sample Mendelian randomization (MR) analysis by utilizing summary statistics from genome-wide association study (GWAS) datasets for both the exposure and outcome variables. Single nucleotide polymorphisms (SNPs) that exhibited significant associations with AAM and ANM were chosen as instrumental variables to estimate the causal effects on sepsis.

Currently, the development of economical and effective non-noble metal electrocatalysts is vital for advancing hydrogen evolution reaction (HER) and enabling its widespread applications. The customizable pore structure and enormous surface area of metal-organic frameworks (MOFs) have made them to become promising non-noble metal electrocatalysts for HER. However, MOFs have some challenges, including low conductivity and instability, which can result in them having high overpotentials and slow reaction kinetics in electrocatalytic processes.

Background: Awake prone positioning has been widely used in non-intubated patients with acute hypoxic respiratory failure (AHRF) due to COVID-19, but the evidence is mostly from observational studies and low-quality randomized controlled trials (RCTs), with conflicting results from published studies. A systematic review of published high-quality RCTs to resolve the controversy over the efficacy and safety of awake prone positioning in non-intubated patients with AHRF due to COVID-19.

Methods: Candidate studies were identified through searches of PubMed, Web of Science, Cochrane, Embase, Scopus databases from December 1, 2019 to November 1, 2022.

Objective: Robotic-assisted laparoscopy (RALS) has gained widespread acceptance in the field of gynecological oncology. However, whether the prognosis of endometrial cancer after RALS is superior to conventional laparoscopy (CLS) and laparotomy (LT) remains inconclusive. Therefore, the aim of this meta-analysis was to compare the long-term survival outcomes of RALS with CLS and LT for endometrial cancer.

Bismuth oxide (BiO) with oxygen vacancies was created using a hydrothermal process and was found to exhibit good catalytic oxidation performance under low-temperature heating without the addition of external oxidants. The catalytic activity of BiO was tested using 4-chlorophenol (4-CP) as the target aqueous pollutant. We observed that 10 ppm of 4-CP was completely degraded within 40 min at a reaction temperature of 65 °C.

As a typical transition-metal sulfides (TMS), nickel disulfide (NiS) has attracted great attention in terms of hydrogen evolution reaction (HER). Howbeit, owing to the poor conductivity, slow reaction kinetics and instability of NiS, its HER activity is still necessary to be improved. In this work, we designed hybrid structures consisting of the nickel foam (NF) as a self-supporting electrode, NiS derived from the sulfuration of NF and Zr-MOF grown on the surface of NiS@NF (Zr-MOF/NiS@NF).

Both academics and policymakers regard publicly planned logistics nodes (PPLN) as a potential measure to promote logistics agglomeration and mitigate environmental damage caused by logistics activities. However, such measure may lead to non-linear carbon emission effect from the perspective of agglomeration economy, and empirical evidences are yet to be found to verify this inference. This paper uses DID method and mediating effect models to explore the effects and mechanisms of PPLN on CO emissions with panel data from 2000 to 2017 in Chengdu, China.
