Comparative impact of tertiary lymphoid structures and tumor-infiltrating lymphocytes in cholangiocarcinoma.

Background: Cholangiocarcinoma is a challenging malignancy with limited responses to conventional therapies, particularly immune checkpoint inhibitor therapy. Tumor-infiltrating lymphocytes (TILs) and tertiary lymphoid structures (TLSs) are key components of the tumor microenvironment (TME) and have been implicated in the immune response to cancer. However, the role and difference of TLSs and TILs in patients with cholangiocarcinoma remains unclear.

Cobalt regulation biocathode with sulfate-reducing bacteria for enhancing the reduction of antimony and the removal of sulfate in a microbial electrolysis cell simultaneously.

Antimony (Sb) contamination in water resources poses a critical environmental and health challenge globally. Sulfate reducing bacteria (SRB) are employed to reduce SO to S for removing Sb in a microbial electrolysis cell (MEC). Yet, the reduction efficiency of reducing SO and Sb(Ⅴ) through SRB remains relatively low, and the underlying mechanism remains elusive.

Immunological characteristics of peripheral T cells as prognostic markers for Camrelizumab and Apatinib combination therapy in advanced squamous non-small-cell lung cancer.

Purpose: To determine the characteristic changes of peripheral blood T cells and identify potential biomarkers that associated with the clinical efficacy of combined immunotherapy and anti-angiogenic therapy in patients with advanced squamous non-small cell lung cancer (NSCLC).

Methods: We performed a comprehensive immunological assessment of peripheral blood mononuclear cell samples from advanced squamous NSCLC patients before and after combination of immunotherapy (Camrelizumab) and anti-angiogenic therapy (Apatinib) using spectral flow cytometry. Correlations between these immunological features and clinical efficacy were analyzed.

Endovascular Thrombectomy for Extracranial Internal Carotid Artery Occlusions With Large Ischemic Strokes: Insights From the SELECT2 Trial.

Background And Objectives: Although previous trials have established the efficacy and safety of endovascular thrombectomy (EVT) in large ischemic core strokes, most of them excluded patients with extracranial internal carotid artery (e-ICA) occlusion. We aimed to compare outcomes in patients with e-ICA occlusion and large ischemic core infarcts treated with EVT vs medical management (MM).

Methods: This was a secondary analysis of the SELECT2 trial, a randomized controlled trial conducted at 31 international sites.

Accelerometer-measured physical activity timing with incident dementia.

Introduction: Moderate to vigorous physical activity (MVPA) is linked to lower dementia risk, though the optimal timing remains unclear.

Methods: Using accelerometer-measured MVPA data from 90,329 dementia-free UK Biobank participants with at least 2 years of follow-up, we assessed associations between MVPA patterns (morning, afternoon, evening, mixed, inactive) and dementia risk via multivariable-adjusted Cox proportional hazards models.

Results: Compared to the inactive group, participants with a tendency of morning MVPA had a lower risk of all-cause dementia (hazard ratio [HR]: 0.

Integrated Genomics Reveal Potential Resistance Mechanisms of PANoptosis-Associated Genes in Acute Myeloid Leukemia.

Acute myeloid leukemia (AML) is marked by the proliferation of abnormal myeloid progenitor cells in the bone marrow and blood, leading to low cure rates despite new drug approvals from 2017 to 2018. Current therapies often fail due to the emergence of drug resistance mechanisms, such as those involving anti-apoptotic pathways and immune evasion, highlighting an urgent need for novel approaches to overcome these limitations. Programmed cell death (PCD) is crucial for tissue homeostasis, with PANoptosis-a form of PCD integrating pyroptosis, apoptosis, and necroptosis-recently identified.

Speckle-illumination spatial frequency domain imaging with a stereo laparoscope for profile-corrected optical property mapping.

Significance: Laparoscopic surgery presents challenges in localizing oncological margins due to poor contrast between healthy and malignant tissues. Optical properties can uniquely identify various tissue types and disease states with high sensitivity and specificity, making it a promising tool for surgical guidance. Although spatial frequency domain imaging (SFDI) effectively measures quantitative optical properties, its deployment in laparoscopy is challenging due to the constrained imaging environment.

Enforced E-selectin ligand installation enhances homing and efficacy of adoptively transferred T cells.

Adoptive T-cell transfer has revolutionized the treatment of hematological malignancies. However, this approach has had very limited success in treating solid tumors, largely due to inadequate infiltration of vascularly administered T cells at tumor sites. The shear-resistant interaction between endothelial E-selectin and its cognate ligand expressed on leukocytes, sialyl Lewis X (sLe), is an essential prerequisite for extravasation of circulating leukocytes.

Oyster Shell Powder/PCL Composite Scaffolds Loaded with Psoralen Nanospheres Promote Large Bone Defect Repair.

Research on bone substitutes for repairing bone defects has drawn increasing attention, and the efficacy of three-dimensional (3D) printed bioactive porous scaffolds for bone defect repair has been well documented. Our previous studies have shown that psoralen can promote osteogenesis by activating the Wnt/β-catenin and BMP/Smad signaling pathways and their crosstalk effects, and psoralen nanospheres have a good osteogenesis-promoting effect with low cytotoxicity. The Chinese medicine oyster shell powder, characterized by its porous structure, strong adsorption, and unique bioactivity, has potential in fracture-promoting repair materials.

In-Situ Construction of LiCl-Rich Artificial Solid Electrolyte Interphase for High-Performance Lithium Metal Anode.

In the pursuit of high-energy-density lithium metal batteries (LMBs), the development of stable solid electrolyte interphase (SEI) is critical to address issues such as lithium dendrite growth and low Coulombic efficiency. Herein, we propose a facile strategy for the in-situ fabrication of a LiCl-rich artificial SEI layer on Li surfaces through reaction of MoCl5 with Li (Li@MoCl5). The resulting artificial SEI significantly enhances the uniformity of Li deposition, effectively suppresses dendrite formation, and improves electrochemical performance.

Immunomodulation effects of collagen hydrogel encapsulating extracellular vesicles derived from calcium silicate stimulated-adipose mesenchymal stem cells for diabetic healing.

Diabetic wounds are characterized by chronic inflammation, reduced angiogenesis, and insufficient collagen deposition, leading to impaired healing. Extracellular vesicles (EVs) derived from adipose-derived mesenchymal stem cells (ADSC) offer a promising cell-free therapeutic strategy, yet their efficacy and immunomodulation can be enhanced through bioactivation. In this study, we developed calcium silicate (CS)-stimulated ADSC-derived EVs (CSEV) incorporated into collagen hydrogels to create a sustained-release system for promoting diabetic wound healing.

Insights into the role of dissolved organic matter derived from paddy soils with different parent materials in the environmental behavior of heavy metal adsorbed by ferrihydrite.

The interaction between dissolved organic matter (DOM) and ferrihydrite (Fh) is a crucial process to control the environmental behavior of heavy metals (HMs) in soil environments, with DOM playing a particularly strong role in HMs fate. Since chemical properties of DOM vary based on different soil parent materials, the underlying impact of DOM-Fh associations on HMs binding remains unclear. This study systematically investigated the interactions between DOM from three soil parent materials (fluvial alluvium: FDOM, sand-shale: SDOM and granite: GDOM) and Fh, and meanwhile understand their effects on the environmental behavior of Cd and Pb under various environmental conditions.
