Exposure to air pollution and non-neoplastic digestive system diseases: findings from the China health and retirement longitudinal study.

Objectives: Increasing concern about air pollution's impact on public health underscores the need to understand its effects on non-neoplastic digestive system diseases (NNDSD). This study explores the link between air pollution and NNDSD in China.

Methods: We conducted a national cross-sectional study using 2015 data from the China Health and Retirement Longitudinal Study (CHARLS), involving 13,046 Chinese adults aged 45 and above from 28 provinces.

A functional hydrogel dressing based on glycyrrhizic acid with low-swelling and moisturizing properties for enhancing infected wound repair.

Wound healing is a challenging due to the presence of bacterial infection, excessive inflammation and angiogenesis disorders. While traditional therapies struggle, a functional hydrogel can effectively repair wounds. However, the use of hydrogels is limited due to their high swelling and excessive dehydration characteristics.

Single-cell transcriptomics reveals over-activated reactive oxygen species pathway in hepatocytes in the development of hepatocellular carcinoma.

Background: Hepatocellular carcinoma (HCC) is a highly heterogeneous tumor and a primary cause of cancer-relevant deaths worldwide. The role of reactive oxygen species (ROS) in HCC development is less studied.

Methods: Seurat package and CellMarker database were employed for single-cell RNA sequencing (scRNA-seq) analysis based on the GSE189175 dataset from Gene Expression Omnibus (GEO).

Significant roles of RNA 5-methylcytosine methylation in cancer.

Cancer stands as a leading cause of mortality and poses an escalating threat to global health. Epigenetic dysregulation is pivotal in the onset and advancement of cancer. Recent research on RNA 5-methylcytosine (mC) methylation has underscored its significant role in cancer.

Comparisons of efficacy and safety of 400 or 800 ml bacterial count fecal microbiota transplantation in the treatment of recurrent hepatic encephalopathy: a multicenter prospective randomized controlled trial in China.

Background: Hepatic encephalopathy (HE) represents a critical complications of end-stage liver disease, serving as an independent predictor of mortality among patients with cirrhosis. Despite effective treatment with rifaximin, some patients with HE still progress to recurrent episodes, posing a significant therapeutic challenge. Recurrent HE is defined as experiencing two or more episodes within a 6-month period.

MYB transcription factors in Peucedanum Praeruptorum Dunn: the diverse roles of the R2R3-MYB subfamily in mediating coumarin biosynthesis.

Background: The MYB superfamily (v-myb avian myeloblastosis viral oncogene homolog) plays a role in plant growth and development, environmental stress defense, and synthesis of secondary metabolites. Little is known about the regulatory function of MYB genes in Peucedanum praeruptorum Dunn, although many MYB family members, especially R2R3-MYB genes, have been extensively studied in model plants.

Results: A total of 157 R2R3-MYB transcription factors from P.

Regulation of Ankyrin-G on Nav1.5 Channel in Hypoxic HL-1 Cardiac Muscle Cells.

Background: Hypoxia has a major regulatory impact on the electrical activity transmission in the myocardium, and it is involved in the development of tachyarrhythmia disease. Anchor protein G (ankyrin-G, ANK-G) is associated with voltage-gated Na channels (Nav1.5), but its specific role and mechanism have not been fully defined.

Exogenous α-Synuclein Induces Oxidative Damage to Dopaminergic Neurons Through p-NMDAR2B/Nur77.

Alpha-synuclein (α-syn) is a major pathological marker of Parkinson's disease (PD), and its abnormal expression and aggregation lead to dopaminergic neuron degeneration, in which oxidative stress plays an important role. However, the exact molecular mechanism by which α-syn causes PD remains unclear. In this study, exogenous α-syn, also known as α-syn preformed fibrils (α-syn PFFs), was used to construct in vivo and in vitro models of PD.

Photothermal-Triggered Extracellular Matrix Clearance and Dendritic Cell Maturation for Enhanced Osteosarcoma Immunotherapy.

Osteosarcoma, a predominant malignant tumor among adolescents, exhibits high mortality and suboptimal immunotherapy efficacy due to a collagen-dense extracellular matrix (ECM) that hinders cytotoxic T lymphocyte (CTL) infiltration. Herein, we developed mesoporous polydopamine (MPDA) nanoparticles encapsulating bromelain and the immune adjuvant R848 (M@B/R), aimed at enhancing photothermal immunotherapy. These nanoparticles efficiently accumulate at the tumor site following injection.

Age and sex-related differences in elastic properties of the gastrocnemius muscle-tendon unit: an observational prospective study.

Introduction: Changes in the mechanical properties of the gastrocnemius muscle-tendon unit can lead to abnormal biomechanics of lower limbs, which is a risk factor for the development of many diseases. However, fewer studies have explored physiological changes in the gastrocnemius muscle-tendon unit stiffness. This study aimed to investigate the age- and sex-related differences in the gastrocnemius muscle-tendon unit stiffness.

Cold atmospheric plasma restores skewed macrophage polarization in triple negative breast cancers via enhancing KAT6A acetylation.

Breast cancer is the most common cancer diagnosed and the second leading cause of death of cancer among women in the world, due to inappropriate diagnosis and choice of therapeutic approach. The molecular profiles of breast cancers may switch among subtypes during treatments, leading to a phenotype such as triple negative breast cancers (TNBCs) that is more difficult to treat. Cold atmospheric plasma (CAP) has been demonstrated by many studies on its efficacy in arresting the malignancies of multiple cancer types including TNBCs that lack surface receptor expression and are thus the most difficult to treat among breast cancers.

[A fluorescence immunochromatography method for detection of human papillomavirus type 16 E6 and L1 proteins].

This study aims to establish a time-resolved fluorescence immunochromatography method for simultaneous determination of human papillomavirus (HPV) type 16 E6 and L1 protein concentrations. The amount of lanthanide microsphere-labeled antibodies, the concentration of coated antibodies, and the reaction time were optimized, and then a test strip for the simultaneous determination of the protein concentrations was prepared. The performance of the detection method was evaluated based on the concordance of the results from clinical practice.

Integrated analysis of single-cell, spatial and bulk RNA-sequencing identifies a cell-death signature for predicting the outcomes of head and neck cancer.

Background: Cell death plays an essential role in carcinogenesis, but its function in the recurrence and postoperative prognosis of head and neck cancer (HNC), which ranks as the 7 most common malignancy globally, remains unclear.

Methods: Data from five main subtypes of HNC related single-cell RNA sequencing (scRNA-seq) were recruited to establish a single-cell atlas, and the distribution of cell death models (CDMs) across different tissues as well as cell subtypes were analyzed. Bulk RNA-seq from the Cancer Genome Atlas Program (TCGA) dataset was subjected to a machine learning-based integrative procedure for constructing a consensus cell death-related signature risk score (CDRscore) model and validated by external data.
