Novel insights into cuproptosis in alcoholic liver disease using bioinformatics analysis and experimental validation.

Cuproptosis is crucial in the development of various liver diseases, yet its involvement in alcoholic liver disease (ALD) remains poorly understood. In this study, we screened cuproptosis-related genes (CRGs) regulating ALD and explored their potential molecular mechanisms. Bioinformatic methods were employed to screen CRGs in ALD, analyze their functional enrichment, signaling pathways, transcriptional regulation, relationship with the immune microenvironment and pathogenic genes, and corresponding single nucleotide polymorphism pathogenic regions, and construct transcription factor-miRNA-mRNA networks.

Sulforaphane regulation autophagy-mediated pyroptosis in autoimmune hepatitis via AMPK/mTOR pathway.

Autoimmune hepatitis (AIH) is a liver disease marked by inflammation of unknown origin. If untreated, it can progress to cirrhosis or liver failure, posing a significant health risk. Currently, effective drug therapies are lacking in clinical practice.

YTHDF3 rs7464 A > G polymorphism increases Chinese neuroblastoma risk: A multiple-center case-control study.

Neuroblastoma (NB), a rare childhood cancer originating in nerve tissue. YTHDF3, a member of the YTH domain protein family, is involved in RNA m6A modification and cancer progression. Polymorphisms in YTHDF3 may influence its expression and biological function.

Identification of Potential Causal Genes for Neurodegenerative Diseases by Mitochondria-Related Genome-Wide Mendelian Randomization.

Current research lacks comprehensive investigations into the potential causal link between mitochondrial-related genes and the risk of neurodegenerative diseases (NDDs). We aimed to identify potential causative genes for five NDDs through an examination of mitochondrial-related gene expression levels. Through the integration of summary statistics from expression quantitative trait loci (eQTL) datasets (human blood and brain tissue), mitochondrial DNA copy number (mtDNA-CN), and genome-wide association studies (GWAS) datasets of five NDDs from European ancestry, we conducted a Mendelian randomization (MR) analysis to explore the potential causal relationship between mitochondrial-related genes and Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Lewy body dementia (LBD).

Nicotine aggravates high-fat diet-induced non-alcoholic fatty liver disease in mice via inhibition of CISD3.

Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease globally. Growing data suggests that smoking plays an important role in the evolution of NAFLD. CDGSH iron sulfur domain 3 (CISD3) regulates critical biological activities.

Coenzyme Q10 ameliorates lipopolysaccharide-induced acute lung injury by attenuating oxidative stress and NLRP3 inflammation through regulating mitochondrial dynamics.

Increasing evidence has demonstrated that coenzyme Q10 (CoQ10) exhibits a range of biological properties. Herein, we explored the protective effect and potential molecular mechanism of CoQ10 on lipopolysaccharide (LPS)-induced acute lung injury (ALI). We found that medium (10 mg/kg) and high (50 mg/kg) doses of CoQ10 ameliorated LPS (50 µg/µL)-induced ALI to varying degrees, as demonstrated by reduced lung coefficient, lower wet/dry weight lung tissue ratio, decreased bronchoalveolar lavage fluid protein concentration, less anatomical and histopathological damage to the lung, and increased expression of proteins related to lung epithelial barrier structure.

FGF4 ameliorates the liver inflammation by reducing M1 macrophage polarization in experimental autoimmune hepatitis.

Background: The global prevalence of autoimmune hepatitis (AIH) is increasing due in part to the lack of effective pharmacotherapies. Growing evidence suggests that fibroblast growth factor 4 (FGF4) is crucial for diverse aspects of liver pathophysiology. However, its role in AIH remains unknown.

Dexmedetomidine Alleviates Acute Stress-Induced Acute Kidney Injury by Attenuating Inflammation and Oxidative Stress via Inhibiting the P2XR/NF-κB/NLRP3 Pathway in Rats.

This study aimed to investigate the potential protective effects of Dexmedetomidine (DEX) against acute kidney injury (AKI) induced by acute stress (AS). Wistar rats were divided into five groups: Control, DEX, AS, AS + DEX, and AS + A438079. The results showed that AS led to AKI by increasing inflammatory biomarkers and oxidative stress-related indicators.

Design and Optimization of NR-Based Stretchable Conductive Composites Filled with MoSi Nanoparticles and MWCNTs: Perspectives from Experimental Characterization and Molecular Dynamics Simulations.

Stretchable conductive composites play a pivotal role in the development of personalized electronic devices, electronic skins, and artificial implant devices. This article explores the fabrication and characterization of stretchable composites based on natural rubber (NR) filled with molybdenum disilicide (MoSi) nanoparticles and multi-walled carbon nanotubes (MWCNTs). Experimental characterization and molecular dynamics (MD) simulations are employed to investigate the static and dynamic properties of the composites, including morphology, glass transition temperature (), electrical conductivity, and mechanical behavior.

A Dynamic Prediction Model for Renal Progression in Primary Membranous Nephropathy.

This study aimed to build and validate a practical web-based dynamic prediction model for predicting renal progression in patients with primary membranous nephropathy (PMN). A total of 359 PMN patients from The First Affiliated Hospital of Fujian Medical University and 102 patients with PMN from The Second Hospital of Longyan between January 2018 to December 2023 were included in the derivation and validation cohorts, respectively. Renal progression was delineated as a decrease in eGFR of 30% or more from the baseline measurement at biopsy or the onset of End-Stage Renal Disease (ESRD).

X-ray Structure-Guided Discovery of a Potent Benzimidazole Glutaminyl Cyclase Inhibitor That Shows Activity in a Parkinson's Disease Mouse Model.

The secretory glutaminyl cyclase (sQC) and Golgi-resident glutaminyl cyclase (gQC) are responsible for N-terminal protein pyroglutamation and associated with various human diseases. Although several sQC/gQC inhibitors have been reported, only one inhibitor, PQ912, is currently undergoing clinic trials for the treatment of Alzheimer's disease. We report an X-ray crystal structure of sQC complexed with PQ912, revealing that the benzimidazole makes "anchor" interactions with the active site zinc ion and catalytic triad.

Experimental research on the impact pressure of tidal bore fronts.

Tidal bore impact can be strong and destructive, placing estuarine infrastructures under great threat. However, there is a lack of research focusing on accurately estimating the impact pressure exerted by tidal bores. Herein new experiments were conducted to investigate the pressure of tidal bore fronts in a glass flume.

Causal association and mediating effect of blood biochemical metabolic traits and brain image-derived endophenotypes on Alzheimer's disease.

Background: Recent genetic evidence supports that circulating biochemical and metabolic traits (BMTs) play a causal role in Alzheimer's disease (AD), which might be mediated by changes in brain structure. Here, we leveraged publicly available genome-wide association study data to investigate the intrinsic causal relationship between blood BMTs, brain image-derived phenotypes (IDPs) and AD.

Methods: Utilizing the genetic variants associated with 760 blood BMTs and 172 brain IDPs as the exposure and the latest AD summary statistics as the outcome, we analyzed the causal relationship between blood BMTs and brain IDPs and AD by using a two-sample Mendelian randomization (MR) method.

Dexmedetomidine affects the NOX4/Nrf2 pathway to improve renal antioxidant capacity.

Objectives: The study aimed to investigate the protective effects of dexmedetomidine (DEX) on renal injury caused by acute stress in rats and explore the protective pathways of DEX on rat kidneys in terms of oxidative stress.

Methods: An acute restraint stress model was utilized, where rats were restrained for 3 hours after a 15-minute swim. Biochemical tests and histopathological sections were conducted to evaluate renal function, along with the measurement of oxidative stress and related pathway proteins.
