Metal exposure could induce oxidative stress, yet the underlying epigenetic mechanisms remain unclear. Herein, we aimed to investigate the DNA methylation signatures associated with oxidative stress biomarkers, including 8-hydroxyguanine (8-OHdG) and 8-iso-prostaglandin-F2α (8-iso-PGF2α), and evaluate their mediating role in metal-induced oxidative stress. A genome-wide DNA methylation association study was conducted in discovery panel (Shiyan, N = 155) with validation in an independent replication panel (Wuhan-Zhuhai, N = 50).

Efficient hierarchical porous carbon (HPC) and heteroatom doping electrode materials remain a formidable challenge for advanced capacitive deionization (CDI) systems for cadmium-containing wastewater purification. This study reports the successful preparation of asymmetric CDI cathodes for the electrosorption of Cd by a controlled dual-organic-salt activation strategy, and its adsorption performance and underlying mechanism were comprehensively investigated. Compared with a single KCO activation strategy, incorporating CHNOSK during activation induced a chain activation-gas etching reaction, resulting in a carbon material with high heteroatom doping, exceptional specific surface area an optimized pore distribution, and abundant edge defects.

Rationale: Uterine inversion is a rare and dangerous obstetric emergency, often occurring in the third stage of labor and leading to severe postpartum hemorrhage. It is less common in low-risk pregnant women, yet its prompt management is crucial. This case report fills a gap in the literature by presenting a rare instance in a low-risk young female, offering clinical insights.

Poly (ethylene oxide) (PEO)-based solid polymer electrolytes (SPEs) are considered one of the most promising electrolytes for all-solid-state lithium metal batteries (ASSLMBs) due to their satisfactory mechanical properties, superior processability, excellent flexibility, and thermal stability. However, the low ionic conductivity at room temperature, the undesired growth of lithium dendrites and solid electrolyte interphase chemistry at the Li/PEO-based SPEs interface, as well as facile decomposition under high-voltage conditions impede their further application. Currently, most researchers devote their interest to the incorporation of various fillers or molecular modification strategies to overcome the mentioned obstacle.

We aim to assess the modification effects of omega-3 polyunsaturated fatty acid (PUFA) levels on relationships between long-term air pollutants exposure and chronic obstructive pulmonary disease (COPD) risk. A total of 82,706 nonsmokers were finally included in the UK Biobank. The concentrations of circulating omega-3 PUFA (including total omega-3 and docosahexaenoic acid [DHA]) were measured by using a targeted high-throughput nuclear magnetic resonance metabolomics platform.

Prolonged inhalation of silica causes silicosis, characterized by persistent lung inflammation and irreversible fibrosis, but the mechanism has not been fully illuminated. In the present study, silicosis cases and healthy controls were employed to access the associations between Toll-like receptor 4 (TLR4) and silicosis risk. Silicosis mouse models and macrophage models were established to investigate whether the TLR4/NF-κB pathway drives pyroptosis through glycolytic reprogramming.

Pyrethroids are extensively used in agriculture and environmental sanitation, but the associations of long-term pyrethroid exposure with glucose dyshomeostasis and the underlying mechanisms remain unclear. This repeated-measures prospective study, comprising 6160 observations (4098 participants at baseline and 2062 participants at the six-year follow-up) from the Wuhan-Zhuhai cohort, measured serum pyrethroids and glucose metabolic traits to assess the cross-sectional and longitudinal associations of pyrethroid exposure with glucose dyshomeostasis. Network toxicological analyses and gene-environment interaction analyses were integrated to identify the underlying targets and mechanisms.

Trial evidence is lacking from real-world community setting regarding whether use of ventilation hood during cooking could reduce household air pollution exposure and bring health benefits. We conducted a cluster-randomized controlled intervention study of using ventilation hood during cooking at five economically underdeveloped villages in southwest China over an 8-month period, where wood remained the dominant cooking fuel. We assessed changes in personal 24-h PM exposure and indicators of cardiometabolic and pulmonary health pre- to post-intervention among 115 intervention and 60 control participants.

Warfarin is widely used in clinical anticoagulation therapy, but the exact mechanism by which it induces vascular calcification (VC) remains unclear. This study aimed to explore the mechanisms of warfarin-induced VC using metabolomics and network toxicology approaches. Initially, normal rats were orally administered warfarin for 2 weeks, and VC was then assessed by serum biochemistry and histopathology.

Introduction: The long-term impacts of exposure to carbon disulfide (CS), a highly concerning air toxicant listed by the Clean Air Act, and its interactions with genetic susceptibility and lifestyle on glucose homeostasis and type 2 diabetes (T2D) in the general population remain unclear and require urgent clarification.

Objectives: To investigate the interactions of CS exposure, genetic susceptibility, and lifestyle on glucose homeostasis and T2D.

Methods: In this prospective study, urinary CS metabolite (2-Thiothiazolidine-4-carboxylic acid, TTCA) and fasting plasma glucose (FPG) and insulin (FPI) for 5294 observations from 2523 participants were repeatedly measured to examine the cross-sectional and longitudinal associations of CS exposure with glucose homeostasis and T2D by performing generalized linear mixed models or COX models.

We introduce an electron-rich hole-transporting material (HTM), , based on a sulfur-rich terthiophene core. This HTM features two triphenylamine donor groups at the 4,4″ positions and four additional triphenylamine groups at the 5,5″ positions connected by vinylene linkages. Its good hole-transporting properties, reduced series resistance, and effective defect passivation contribute to the improved performance.

Evidence on the impacts of volatile organic compounds (VOCs), a class of ubiquitous environmental toxics, on sarcopenia, a major age-related global health issue, remains scarce. Data from 3007 adults in the National Health and Nutrition Examination Survey (2011-2018) were analyzed to assess the individual and mixture effects of 16 VOCs metabolites (VOCMs) on sarcopenia using multivariate logistic regression, weighted quantile sum (WQS), and Bayesian kernel machine regression (BKMR) models. Network pharmacology was employed to explore potential underlying mechanisms.

Synthetic lethality has emerged as a pivotal concept in cancer therapy, offering novel and promising strategies for treatment. In this study, we identified molecular subtypes associated with synthetic lethality in breast cancer and developed a prognostic signature based on synthetic lethality-related genes. Using the TCGA cohort, we screened differentially expressed synthetic lethal genes (DESLGs) and stratified patients into two distinct molecular subtypes based on their expression patterns.

Long non-coding RNAs (lncRNAs) are closely associated with the regulation of gene expression, whose promoters play a crucial role in comprehensively understanding lncRNA regulatory mechanisms, functions and their roles in diseases. Due to limitations of the current techniques, accurately identifying lncRNA promoters remains a challenge. To address this challenge, we propose a support vector machine (SVM)-based method for predicting lncRNA promoters, called SVM-LncRNAPro.
