Gut dysbiosis-induced vitamin B6 metabolic disorder contributes to chronic stress-related abnormal behaviors in a cortisol-independent manner.

Chronic stress can result in various conditions, including psychological disorders, neurodegenerative diseases, and accelerated brain aging. Gut dysbiosis potentially contributes to stress-related brain disorders in individuals with chronic stress. However, the causal relationship and key factors between gut dysbiosis and brain disorders in chronic stress remain elusive, particularly under non-sterile conditions.

Key Node Identification Method Based on Multilayer Neighbor Node Gravity and Information Entropy.

In the field of complex network analysis, accurately identifying key nodes is crucial for understanding and controlling information propagation. Although several local centrality methods have been proposed, their accuracy may be compromised if interactions between nodes and their neighbors are not fully considered. To address this issue, this paper proposes a key node identification method based on multilayer neighbor node gravity and information entropy (MNNGE).

Metabolic engineering of Bacillus licheniformis DW2 for ectoine production.

Ectoine is a high-value protective agent with extensive applications in the fields of fine chemicals and biopharmaceuticals, and it is naturally synthesized by Halomonas in extreme environment, however, the current production level cannot meet the growing market demand. In this study, we aimed to develop an efficient and environmentally friendly ectoine production process using Bacillus licheniformis as the host organism. Through introducing ectoine synthetase gene cluster ectABC from Halomonas elongate, as well as optimizing ectABC expression by promoter and 5'-UTR optimization, ectoine titer was increased to 0.

Nitric Oxide-Releasing Nanoscale Metal-Organic Layer Overcomes Hypoxia and Reactive Oxygen Species Diffusion Barriers to Enhance Cancer Radiotherapy.

Hafnium (Hf)-based nanoscale metal-organic layers (MOLs) enhance radiotherapeutic effects of tissue-penetrating X-rays via a unique radiotherapy-radiodynamic therapy (RT-RDT) process through efficient generation of hydroxy radical (RT) and singlet oxygen (RDT). However, their radiotherapeutic efficacy is limited by hypoxia in deep-seated tumors and short half-lives of reactive oxygen species (ROS). Herein the conjugation of a nitric oxide (NO) donor, S-nitroso-N-acetyl-DL-penicillamine (SNAP), to the Hf secondary building units (SBUs) of Hf-5,5'-di-p-benzoatoporphyrin MOL is reported to afford SNAP/MOL for enhanced cancer radiotherapy.

Coenzyme Q10 Alleviates Silicosis Fibrosis Inhibiting Ferroptosis in Mice.

Background/aim: Silicosis, the most severe type of occupational pneumoconiosis, leads to diffuse pulmonary fibrosis without specific therapy. Ferroptosis is triggered by reactive oxygen species (ROS) and Fe overload-induced lipid peroxidation, which is involved in the progression of pulmonary fibrosis. As an important coenzyme in the process of aerobic respiration, Coenzyme Q10 (CoQ10) can enhance mitochondrial function and energy supply and reduce malondialdehyde (MDA) to limit the risk of fibrosis.

Advances in Machine Learning-Aided Thermal Imaging for Early Detection of Diabetic Foot Ulcers: A Review.

The prevention and early warning of foot ulcers are crucial in diabetic care; however, early microvascular lesions are difficult to detect and often diagnosed at later stages, posing serious health risks. Infrared thermal imaging, as a rapid and non-contact clinical examination technology, can sensitively detect hidden neuropathy and vascular lesions for early intervention. This review provides an informative summary of the background, mechanisms, thermal image datasets, and processing techniques used in thermal imaging for warning of diabetic foot ulcers.

Human microbiome-derived peptide affects the development of experimental autoimmune encephalomyelitis via molecular mimicry.

Tendon Groove Technique: A Double-Bundle Footprint Technique for Anterior Cruciate Ligament Reconstruction.

Double-bundle (DB) anterior cruciate ligament (ACL) reconstruction has biomechanical advantages over single-bundle reconstruction. However, most studies perform the DB reconstruction with 2 femoral tunnels, which fails to provide an entire femoral footprint for ACL reconstruction. In this study, we describe a femoral double-bundle footprint technique for ACL reconstruction, named the tendon groove technique.

Ginsenoside Rh2 promotes cell apoptosis in T-cell acute lymphocytic leukaemia by MAPK and PI3K/AKT signalling pathways.

Weight loss in patients on osimertinib for metastatic EGFR-mutant non-small cell lung cancer.

Background: Cachexia is characterized by weight loss and decline in muscle mass and function and is a poor prognostic factor among patients with cancer. Patients with metastatic EGFR-mutant non-small cell lung cancer (NSCLC) derive remarkable survival benefits with osimertinib, a third-generation EGFR tyrosine kinase inhibitor. It is not known whether patients treated with osimertinib experience any weight loss or whether weight loss impacts patient outcomes.

Melatonin protects bovine oocyte from βHB-induced oxidative stress through the Nrf2 pathway.

Accumulation of ketone bodies in the blood or tissues can trigger ketosis, exerting detrimental effects on bovine oocytes maturation. Exposure to its primary component, β-hydroxybutyric acid (βHB), disrupts mitochondrial function, culminating in the excessive buildup of reactive oxygen species (ROS) and subsequent initiation of apoptosis in oocytes. These ultimately result in poor oocyte quality.
