An advanced chitosan based sponges dressing system with antioxidative, immunoregulation, angiogenesis and neurogenesis for promoting diabetic wound healing.

Promoting wound nerve regeneration and synchronously initiating angiogenesis are critical factors in the healing process of diabetic wounds. However, existing research on diabetic wounds mainly focuses on angiogenesis, bacterial infection and reactive oxygen species, often failing to coordinate neurogenesis and angiogenesis. To coordinate the symbiosis of nerves and blood vessels in the diabetic wounds, we successfully designed a multifunctional chitosan (CS)-based sponges by regulating the structure of CS specifically for diabetic wound healing.

O-GlcNAcylation of progranulin promotes hepatocellular carcinoma proliferation.

Progranulin (PGRN) is overexpressed and implicated in hepatocellular carcinoma (HCC) development; however, its post-translational modifications and regulatory mechanisms in HCC remain largely unexplored. Here, the expression levels of PGRN, OGT, and O-GlcNAcylation were found to be elevated in both HCC samples and cell lines. LC-MS/MS analysis and immunoprecipitation revealed that PGRN underwent O-linked N-acetylglucosamine (O-GlcNAc) modification at threonine 272 (Thr272).

Development and application of a predictive model for survival and drug therapy based on COVID-19-related lncRNAs in non-small cell lung cancer.

Numerous studies have substantiated the pivotal role of long non-coding RNAs (lncRNAs) in the progression of non-small cell lung cancer (NSCLC) and the prognosis of afflicted patients. Notably, individuals with NSCLC may exhibit heightened vulnerability to the novel coronavirus disease (COVID-19), resulting in a more unfavorable prognosis subsequent to infection. Nevertheless, the impact of COVID-19-related lncRNAs on NSCLC remains unexplored.

Confidence Intervals for the Risk Difference Between Secondary and Primary Infection Based on the Method of Variance Estimates Recovery.

The risk difference (RD) between the secondary infection, given the primary infection, and the primary infection can be a useful measure of the change in the infection rates of the primary infection and the secondary infection. It plays an important role in pharmacology and epidemiology. The method of variance estimate recovery (MOVER) is used to construct confidence intervals (CIs) for the RD.

An endogenous aryl hydrocarbon receptor ligand induces preeclampsia-like phenotypes in rats.

Preeclampsia (PE) is a hypertensive disorder during human pregnancy. Aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor. Exogenous and endogenous AhR ligands can induce hypertension in male rats and mice.

Inhibition of the Wnt/β‑catenin signaling pathway and SOX9 by XAV939 did not alleviate inflammation in a dextran sulfate sodium‑induced ulcerative colitis model.

The Wnt/β-catenin signaling pathway has been reported to be hyperactivated during the pathogenesis of ulcerative colitis (UC). The present study aimed to explore the therapeutic efficacy of the Wnt/β-catenin signaling inhibitor XAV939 in mitigating UC symptoms. Utilizing a dextran sulfate sodium (DSS)-induced UC mouse model, the present study aimed to evaluate the impact of XAV939 on intestinal morphology through hematoxylin and eosin staining and to measure the expression levels of critical proteins in the Wnt/β-catenin signaling cascade.

Identification and validation of apoptosis-related genes in acute myocardial infarction based on integrated bioinformatics methods.

Background: Acute myocardial infarction (AMI) is one of the most serious cardiovascular diseases. Apoptosis is a type of programmed cell death that causes DNA degradation and chromatin condensation. The role of apoptosis in AMI progression remains unclear.

Effectiveness of abdominal electroacupuncture therapy for poststroke constipation: a meta-analysis.

Background: Electroacupuncture (EA) has been employed to address the symptoms of constipation in individuals who have experienced a stroke. However, supporting evidence for its efficacy is lacking. This meta-analysis aims to investigate whether EA was effective in treating poststroke constipation.

Novel insights into Cntnap4 in Alzheimer's disease: Intestinal flora interaction.

Alzheimer's disease (AD) is a neurodegenerative disorder with unclear etiology. This study employs single-cell RNA sequencing (scRNA-seq), high-throughput transcriptome sequencing, 16s rRNA sequencing, and animal experiments to investigate the role of the contactin-associated protein like-4 (Cntnap4) gene in AD and its interaction with intestinal flora. We found that Cntnap4 deficiency in AD mice led to increased Tau protein phosphorylation, amyloid-beta plaque accumulation, and neuronal loss.

Relevance of peripheral inflammation indexes in different collateral circulation for intracranial hemorrhage in acute anterior circulation ischemic stroke patients undergoing endovascular treatment.
