MS4A6A regulates ox-LDL-induced endothelial dysfunction and monocyte adhesion in atherosclerosis via the IKK/NF-kappaB pathway.

Atherosclerosis (AS) is characterized by chronic inflammation, which is a significant pathogenic factor of cardiovascular diseases (CVDs). Alleviating endothelial dysfunction and monocyte adhesion are effective ways to halt the development of AS. Membrane Spanning 4-Domains A6A (MS4A6A) is associated with inflammation and primarily regulates immunity and cell signaling.

Anion-mediated approach to overcome oxidation in ether electrolytes for high-voltage sodium-ion batteries.

The ether-based electrolytes are acknowledged for their compatibility with a diverse array of sodium-ion battery anodes, as well as their capability to enable efficient and reversible electrochemical reactions. However, they encounter a challenge of oxidation at high voltages. We find that a standard diglyme-based electrolyte starts to oxidize and break down at voltages exceeding 3.

Phase 2 study of chidamide in combination with CAG and venetoclax-azacitidine in older patients with newly diagnosed acute myeloid leukemia.

Introduction: Older patients with acute myeloid leukemia (AML) respond poorly to standard induction therapy. DNA methyltransferases (DNMTs) and histone-deacetylases (HDACs) are key regulators of gene expression in cells and have been investigated as important therapeutic targets. However, their effects remains unclear as induction therapy for AML.

Size-effect induced controllable Cu-Cu sites for ampere-level nitrate electroreduction coupled with biomass upgrading.

However, the mechanistic understanding and the roles of Cu and Cu remain exclusive. The big obstacle is that it is challenging to effectively regulate the interfacial motifs of Cu-Cu sites.

Chidamide in Combination With DCAG With or Without Venetoclax for Relapsed/Refractory Acute Myeloid Leukemia.

Introduction: Currently, there are only a few avaailable treatment options for patients with relapsed and refractory acute myeloid leukemia (R/R AML).

Methods: We conducted a single-center, phase 1 prospective study (ChiCTR2200065634) to evaluate the efficacy and safety of chidamide, demethylating drugs (azacitidine), cytarabine, aclacinomycin, and G-CSF plus venetoclax (CDCAG-VEN) in patients with R/R AML. The previous CDCAG regimen was used as a historical control to compare its efficacy and safety.

Giant structurally modulated intrinsic chirality of quasi-bound states in continuum.

Structurally modulated intrinsic chirality is a structural transformation phenomenon in photoresponsive molecules that is commonly utilized in biosensing and chemical analysis. In this study, we proposed an approach to achieve giant intrinsic chirality in a quasi-bound state in the continuum (Q-BICs)-slanted tetramer metasurface, where high Q factors and circular dichroism (CD) coexist. Empowered by the simultaneous resonance between toroidal dipole (TD) and electric quadrupole (EQ) modes, the intrinsic circular dichroism can be effectively tuned via variations in the slant angles of the metasurface.

Acute myeloid leukemia (AML) is a highly heterogeneous hematopoietic malignancy characterized by elevated mortality. Epigenetic therapy plays an essential role in the treatment of AML. However, the clinical outcomes of the combination of multiple epigenetic agents and conventional chemotherapy remain unclear.

An infrared dataset for partially occluded person detection in complex environment for search and rescue.

The combination of unmanned aerial vehicles (UAVs) and deep learning has potential applicability in various complex search and rescue scenes. However, due to the presence of environmental occlusions such as trees, the performance of UAVs mounted with different optical payloads in detecting missing persons is poor. To the best of our knowledge, currently available non-occluded human target datasets are insufficient to address the challenges of automatic recognition for partially occluded human targets.

Salicylic acid induces the formation of supramolecular antimicrobial hydrogels from worm-like micelles.

The incorporation of salicylic acid (SA) facilitates the gelation of worm-like micelles (WLMs) derived from sodium lauroyl glutamate (LGS) and cetyltrimethylammonium bromide (CTAB) under acidic conditions, thereby constructing a pH-responsive supramolecular hydrogel system. SA significantly enhances the transition from WLMs to the gel state, as evidenced by changes in the storage modulus (') and loss modulus (''), highlighting its pivotal role in dynamic network crosslinking. The electrostatic interaction between CTAB and LGS provides a foundation for the formation of the LGS/CTAB/SA hydrogel.

This study comprehensively examined the antibacterial performance of these composite materials with different morphologies against E.

Advancing band structure simulations of complex systems of C, Si and SiC: a machine learning driven density functional tight-binding approach.

We present a machine learning (ML) workflow for optimizing electronic band structures using density functional tight binding (DFTB) to replicate the results of costly hybrid functional calculations. The workflow is trained on carbon, silicon, and silicon carbide systems, encompassing bulk, slab, and defect geometries. Our method accurately reproduces hybrid functional results by applying a DFTB-ML scheme to train and predict the scaling parameters of two-center integrals and on-site energies, which is particularly accurate for electronic band structures near the Fermi energy.

Analysis of Clinical Characteristics and Risk Factors for Severe Influenza A and Influenza B in Children.

Purpose: The goal of this study was to develop and validate an online dynamic nomogram system for early differential diagnosis of influenza A and B.

Methods: Patients with severe influenza A and B admitted to Henan Children's Hospital from January 2019 to January 2022 were used as the modeling group (n = 161), and patients admitted from January to September 2023 were used as the validation group (n = 52). Univariate logistic regression and multivariate logistic regression were used to identify the risk variables of severe influenza A and B in children in the modeling group.

Physics and Chemistry of Two-Dimensional Triangulene-Based Lattices.

ConspectusTriangulene (TRI) and its heterotriangulene (HT) derivatives are planar, triangle-shaped molecules that, via suitable coupling reactions, can form extended organic two-dimensional (2D) crystal (O2DC) structures. While TRI is a diradical, HTs are either closed-shell molecules or monoradicals which can be stabilized in their cationic form.Triangulene-based O2DCs have a characteristic honeycomb-kagome lattice.

Anti-PD-1 combined with hypomethylating agent and CAG regimen bridging to allogeneic hematopoietic stem cell transplantation: a novel strategy for relapsed/refractory acute myeloid leukemia.

Introduction: The prognosis of relapsed/refractory acute myeloid leukemia (r/rAML) is dismal, and allogeneic hematopoietic stem cell transplant (allo-HSCT) is a potential cure. Combining anti-PD-1, hypomethylating agent (HMA), and CAG (cytarabine, aclarubicin/idarubicin, granulocyte colony-stimulating factor) regimen has showed primary efficacy in r/rAML. However, pre-transplant exposure to anti-PD-1 may lead to severe graft-versus-host disease (GVHD).

Similar Survival But Less Chronic GVHD in Antithymocyte Globulin-Based Myeloablative Haploidentical Transplant Compared With Matched Sibling Transplant for Adult T-cell Acute Lymphoblastic Leukemia/Lymphoma.

The annual number of human leukocyte antigen (HLA)-haploidentical allogeneic hematopoietic stem cell transplantation (haplo-HCT) is increasing steadily. Comparative studies about haplo-HCT versus HCT with HLA-matched sibling donors (MSD-HCT) have been tried in acute myeloid leukemia and B-cell acute lymphoblastic leukemia/lymphoma (ALL). Few studies were reported in adult T-cell ALL (T-ALL).

The effectiveness of probiotic products hinges on the viability and precise quantification of probiotic strains. This study addresses this crucial requirement by developing and validating a precise propidium monoazide combination with quantitative polymerase chain reaction (PMA-qPCR) method for quantifying viable in probiotic formulations. Initially, species-specific primers were meticulously designed based on core genes from the whole-genome sequence (WGS) of , and they underwent rigorous validation against 462 WGSs, 25 target strains, and 37 non-target strains across various taxonomic levels, ensuring extensive inclusivity and exclusivity.

Selective CO Reduction over γ-Graphyne Supported Single-Atom Catalysts: Crucial Role of Strain Regulation.

The two-electron CO reduction reaction (2e-CORR) is the most promising process for realizing industrial utilization of CO, but it is hindered by the competitive hydrogen evolution reaction (HER) because of the comparable equilibrium potential. Strategies to enhance 2e-CORR activity and selectivity by suppressing HER are highly demanded. Inspired by the low in-plane Young's modulus of the recently synthesized γ-graphyne (GY), we propose tensile-strain regulation as an effective method to improve the selectivity of the CORR against HER.

Giant strong coupling in a Q-BICs' tetramer metasurface.

Due to their ultrahigh Q-factor and small mode volume, bound states in the continuum (BICs) are intriguing for the fundamental study of the strong coupling regime. However, the strong coupling generated by BICs in one metasurface is not always strong enough, which highly limits its efficiency in applications. In this work, we realize a giant strong coupling of at most 60 meV in a quasi-BICs' (Q-BICs) tetramer metasurface composed of four Si cylinders with two different sets of diagonal lengths.

Clonal Hematopoiesis-Associated Gene Mutations Affect Acute Graft-Versus-Host Disease After Hematopoietic Stem Cell Transplantation in AML Patients.

BACKGROUND The relationship between clonal hematopoiesis (CH)-associated gene mutations and allogeneic hematopoietic stem cell transplantation (allo-HSCT) has been extensively studied since next-generation sequencing (NGS) technology became widely available. However, research has mainly focused on the relationship between donor CH mutations and transplant prognosis, and research into the relationship between CH mutations in the recipient and acute graft-versus-host disease (aGVHD) is lacking. MATERIAL AND METHODS We analyzed NGS results and their correlation with aGVHD and prognosis in 196 AML patients undergoing allo-HSCT.

Bifunctional oxygen reduction/evolution reaction electrocatalysts achieved by axial ligand modulation on two-dimensional porphyrin frameworks.

Exploring efficient and low-cost oxygen reduction and oxygen evolution reaction (ORR/OER) bifunctional catalysts is essential for the development of energy storage and conversion devices. Herein, enlightened by the experimentally synthesized cobalt(II) -tetraethynylporphyrins (Co-TEP) molecule, we designed a novel 2D covalent organic framework (COF), namely a 2D Co-TEP monolayer, by dimensional expansion. The 2D Co-TEP monolayer, with Co atoms distributed separately and stabilized by uniform pyrrolic-N coordination, features metal-nitrogen-carbon single-atom catalyst activity and shows tunable catalytic activity for the electrochemical ORR/OER by axial ligand (O, OH, Cl, CN, CH, NO, F) modulation.
