Microbiome depletion by broad-spectrum antibiotics does not influence demyelination and remyelination in cuprizone-treated mice.

Demyelination in the central nervous system (CNS) is a feature of various psychiatric and neurological disorders. Emerging evidence suggests that the gut-brain axis may play a crucial role in CNS demyelination. The cuprizone (CPZ) model, which involves the administration of CPZ-containing food pellets, is commonly used to study the effects of different compounds on CNS demyelination and subsequent remyelination.

Activated neutrophil membrane-coated tRF-Gly-CCC nanoparticles for the treatment of aortic dissection/aneurysm.

Aortic dissection/aneurysm (AAD) is a critical and life-threatening condition marked by a lack of effective pharmacological treatments. Gene therapy has emerged as a promising approach to treat AAD and slow its advancement. However, the clinical utility of gene therapy is impeded by significant challenges, including the scarcity of innovative genetic drugs in current medical practices and the absence of a streamlined gene delivery mechanism.

Machine learning-motivated trace triethylamine identification by bismuth vanadate/tungsten oxide heterostructures.

Triethylamine, an extensively used material in industrial organic synthesis, is hazardous to the human respiratory and nervous systems, but its accurate detection and prediction has been a long-standing challenge. Herein, a machine learning-motivated chemiresistive sensor that can predict ppm-level triethylamine is designed. The zero-dimensional (0D) bismuth vanadate (BiVO) nanoparticles were anchored on the surface of three-dimensional (3D) tungsten oxide (WO) architectures to form hierarchical BiVO/WO heterostructures, which demonstrates remarkable triethylamine-sensing performance such as high response of 21 (4 times higher than pristine WO) at optimal temperature of 190 °C, low detection limit of 57 ppb, long-term stability, reproducibility and good anti-interference property.

Enhancing the sustainability of rubber materials: Dual benefits of wet mixing technology and recycled rubber's honeycomb reinforcement structure.

The world's three leading tire manufacturers have proposed specific timelines for using recycled materials. For instance, Michelin targets an increase in the proportion of sustainable materials in tires to 40 % by 2030 and aims to produce 100 % of its tires from bio-based, renewable, or recyclable materials as of 2050. In such a context, this study introduced wet mixing technology to apply recycled rubber (RR) in highly wear-resistant tire tread compounds.

Prognostic value of pre-ablation stimulated thyroglobulin in children and adolescents with differentiated thyroid cancer.

Aim: To investigate the prognostic value of pre-ablation stimulated thyroglobulin (ps-Tg) in children and adolescents with persistent differentiated thyroid cancer (DTC) following initial radioiodine therapy (RAI).

Microglia in morphine tolerance: cellular and molecular mechanisms and therapeutic potential.

Morphine has a crucial role in treating both moderate to severe pain and chronic pain. However, prolonged administration of morphine can lead to tolerance of analgesia, resulting in increased doses and poor treatment of pain. Many patients, such as those with terminal cancer, require high doses of morphine for long periods.

Research trend and hotspots of polycystic ovary syndrome with depression from 1993 to 2024: a bibliometric analysis.

Background: Polycystic ovary syndrome (PCOS), a common endocrine disorder, affects women of reproductive age, and its adverse consequences affect women throughout their lifespan, from adolescence to postmenopause. The prevalence of depression is much higher in women with PCOS than in healthy controls. Thus, it is recommended that depressive syndrome be screened routinely in all patients with PCOS at diagnosis.

Chinese guidelines for minimally invasive donor hepatectomy in living donor liver transplantation (2024 edition).

Background: Minimally invasive surgeries are increasingly central to modern medicine, particularly in liver transplantation. These techniques, which offer reduced trauma, precise operations, minimal bleeding, and swift recovery, are, however, unevenly adopted across China. Only a limited number of centers routinely perform minimally invasive donor hepatectomies, indicating a significant imbalance in the development and application of these advanced procedures.

Astaxanthin Increases Tumor Suppressor Gene Expression and Affects Cellular Biological Behavior in Oral Dysplastic Keratinocytes by Regulating DNA Methylation.

Background: The inactivation of tumor suppressor genes (TSGs) caused by abnormal DNA methylation is confirmed to be widely present in oral potential malignant diseases (OPMDs). Carotenoids like lycopene and astaxanthin can regulate DNA methylation and exert anticancer effects. Therapeutic effect of astaxanthin in OPMDs and oral squamous cell carcinoma (OSCC) models is confirmed, but the relationship between the anti-cancer ability of astaxanthin and its DNA methylation regulation ability remains unclear.

Insights Into the Role of π-Electrons of Aromatic Aldehydes in Passivating Perovskite Defects.

Carbonyl-containing aromatic ketones or aldehydes have been demonstrated to be effective defect passivators for perovskite films to improve performances of perovskite solar cells (PSCs). It has been claimed that both π-electrons within aromatic units and carbonyl groups can, separately, interact with ionic defects, which, however, causes troubles in understanding the passivation mechanism of those aromatic ketone/aldehyde molecules. Herein, we clarify the effect of both moieties in one molecule on the defect passivation by investigating three aromatic aldehydes with varied conjugation planes, namely, biphenyl-4-carbaldehyde (BPCA), naphthalene-2-carbaldehyde (NACA) and pyrene-1-carbaldehyde (PyCA).

The Crosstalk between Autophagy and Nrf2 Signaling in Cancer: from Biology to Clinical Applications.

Autophagy is a catabolic process that has been conserved throughout evolution, serving to degrade and recycle cellular components and damaged organelles. Autophagy is activated under various stress conditions, such as nutrient deprivation, viral infections, and genotoxic stress, and operates in conjunction with other stress response pathways to mitigate oxidative damage and maintain cellular homeostasis. One such pathway is the Nrf2-Keap1-ARE signaling axis, which functions as an intrinsic antioxidant defense mechanism and has been implicated in cancer chemoprevention, tumor progression, and drug resistance.
