Hepatocellular carcinoma (HCC) is the most prevalent form of liver tumor, characterized by restricted therapeutic options and typically low long-term survival rates. Recently, immunotherapy has revolutionized HCC treatment, making the tumor microenvironment (TME) a research focus. Radiomics is increasingly crucial in HCC clinical decisions, offering advanced tools for TME characterization and prognosis assessment.

Allergic asthma is a chronic complex airway disease characterized by airway hyperresponsiveness, eosinophilic inflammation, excessive mucus secretion, and airway remodeling, with increasing mortality and incidence globally. The pathogenesis of allergic asthma is influenced by various factors including genetics, environment, and immune responses, making it complex and diverse. Recent studies have found that various cellular functions of mitochondria such as calcium regulation, adenosine triphosphate production, changes in redox potential, and free radical scavenging, are involved in regulating the pathogenesis of asthma.

Article Synopsis
  • The probiotic E. coli Nissle 1917 (EcN) was studied for its effects on atherosclerosis in mice fed a high-fat diet, revealing its potential to alleviate disease progression.
  • EcN treatment reduced atherosclerotic plaque formation, improved cholesterol levels, and inhibited the expression of pyroptosis-related proteins linked to inflammation.
  • Further analysis showed that EcN regulated gut microbiota and metabolite levels, suggesting a mechanism for its beneficial effects, although antibiotics partially reversed these outcomes.

Immunochemotherapy is Currently the standard first-line treatment for advanced esophageal squamous cell carcinoma (ESCC). However, its prognosis remains unsatisfactory. We aimed to evaluate the efficacy and safety of immunochemotherapy plus radiotherapy (ICR) compared with immunochemotherapy (IC) alone as a first-line treatment for advanced ESCC.

Background: Anti-programmed cell death 1 (PD-1) antibody combined with chemotherapy simultaneously is regarded as the standard treatment for patients with advanced non-small cell lung cancer (NSCLC) by current clinical guidelines. Different immune statuses induced by chemotherapy considerably affect the synergistic effects of the chemo-anti-PD-1 combination. Therefore, it is necessary to determine the optimal timing of combination treatment administration.

Background: Autoantibodies can be readily identified prior to biopsy and may serve as valuable biomarkers for cancer detection. Ferredoxin 1 (FDX1) is a key regulator in the process of cuproptosis and affects the prognosis of lung cancer. In this study, we investigated whether the anti-FDX1 autoantibody could serve as a novel biomarker for the detection of non-small cell lung cancer (NSCLC).

The generalized Kerker effect (GKE) arising from the interference of high-order multipoles has attracted more interest due to its direct correlation with various functionalities in nanophotonics. The realization of the GKE at oblique incidence is highly desired yet remains underexplored. Herein, we report the experimental observation of the GKE by leveraging quasi-bound states in the continuum (QBICs) supported by a silicon metasurface.

Vascular calcification (VC) in type 2 diabetes (T2D) poses a serious threat to the life and health of patients. However, its pathogenesis remains unclear, resulting in a lack of effective treatment for the root cause. It is found that both intestinal Bacteroides fragilis (BF) and peripheral M2 monocytes/macrophages are significantly elevated in patients with T2D VC.

Acrolein (ACR) is an α,β-unsaturated aldehyde with high reactivity towards nucleophiles in proteins. In this study, a typical phenolic compound phloretin (Phl) was employed to counteract protein modification induced by ACR (1 mM) in whey protein isolate (WPI, 10 mg/mL). The addition of Phl (2 mM) significantly reduced ACR-induced surge of protein carbonyls (from 1.

Background: Approximately 60% of Asian populations with non-small cell lung cancer (NSCLC) harbor epidermal growth factor receptor (EGFR) gene mutations, marking it as a pivotal target for genotype-directed therapies. Currently, determining EGFR mutation status relies on DNA sequencing of histological or cytological specimens. This study presents a predictive model integrating clinical parameters, computed tomography (CT) characteristics, and serum tumor markers to forecast EGFR mutation status in NSCLC patients.

Fe-based catalysts are commonly applied in the process of Fischer-Tropsch synthesis (FTS) to olefins, with Hägg iron carbide (FeC) recognized as the primary active phase. However, iron carbonyls, the raw materials for wet chemical synthesis of FeC, are expensive and toxic, which limits large-scale preparation. Here, a cost-effective and versatile method is proposed for the synthesis of FeC nanoparticles (NPs) with nanosized zero-valent iron (abbreviated as NZVI, prepared by reducing iron salts or ball-milling iron powder) instead of iron carbonyls, achieving a cost reduction of 76.

  • * A study in rural China shows that while most households have separated kitchens, only a fraction use ventilation fans, and adoption is largely affected by income and education.
  • * Implementing ventilation fans and separated kitchen designs could prevent around 67,400 premature deaths each year, providing health benefits worth about USD 19 billion annually, making it a feasible alternative to the challenges of transitioning to clean energy.

The importance of CD4 T cells in cancer immunotherapy has gained increasing recognition. Particularly, a specific subset of CD4 T cells coexpressing the T helper type 1 (Th1) and Th17 markers has demonstrated remarkable antitumor potential. However, the underlying mechanisms governing the differentiation of these cells and their subsequent antitumor responses remain incompletely understood.

As environmental issues are hotly debated worldwide, finding suitable materials to replace petroleum-based materials as the next-generation packaging materials has become a research hotspot. Nanocellulose, as a biomass material widely available in nature, is favored for application in green packaging materials due to its environmentally friendly and bio-friendly characteristics. However, the unstable mechanical properties and strong hydrophilicity of nanocellulose limit its practical application in packaging materials.

Cell death is a central process for organismal health. Pyroptosis, namely pyroptotic cell death, is recognized as a critical type that disrupts membrane and triggers pro-inflammatory cytokine secretion gasdermins, providing a robust form of cytolysis. Meanwhile, along with the thorough research, a great deal of evidence has demonstrated the dual effects of pyroptosis in host defense and inflammatory diseases.

Unilateral hydrophobic flocculant and unsatisfactory floc separation constrained the efficacious purification of oil-containing wastewater. Illumined by the hunting behavior of mimic octopus, a biomimetic flocculant (CNSDA) with temperature-sensitive chains (color pouch) and hollow silica cores (mantle) was manufactured to derive hydrophilic-hydrophobic convertibility and auto-separation capabilities. Physical-chemical information of CNSDA was elucidated through characterization analysis.

On construction sites impacted by particulate matter and hazardous gases, portable integrated air filtration equipment with high efficiency, minimal pressure drops and ammonia (NH) alarms is critical. Triboelectric nanogenerators (TENG) present a sustainable solution by generating self-powered electricity to fulfill these requirements. In this study, we synthesized zeolitic imidazolate framework-8 (ZIF-8) in situ on the surface of titanium carbide (TiCT) to create TiCT/ZIF-8, grafted it onto cellulose diacetate via tetraethyl orthosilicate, and ultimately developed a cellulose-based nanofibrous membrane through electrospinning, combining it with a negative triboelectric material to construct a self-powered TENG-based mask.
