The transcription factor GmbZIP131 enhances soybean salt tolerance by regulating flavonoid biosynthesis.

Detoxifying reactive oxygen species (ROS) that accumulate under saline conditions is crucial for plant salt tolerance. The Salt Overly Sensitive (SOS) pathway functions upstream, while flavonoids act downstream, in ROS scavenging under salt stress. However, the potential crosstalk between the SOS pathway and flavonoids in regulating salt stress responses and the associated mechanisms remain largely unexplored.

A High-Modulus Dual-Cross-Linked Shell Promoting Phosphorus-Carbon Composites for Stable and High-Rate Lithium Ion Storage.

Phosphorus is considered an ideal anode material for lithium ion storage by virtue of its high theoretical capacity and moderate lithiation potential. However, issues such as large volume expansion of phosphorus leading to an electrical loss of contact and instability of the solid electrolyte interface hinder its practical performance. Improvement strategies that can effectively suppress volume expansion and provide stable electrical contacts are urgently needed.

Phase Change-Mediated Capture of Carbon Dioxide from Air with a Molecular Triamine Network Solid.

The efficient removal of CO from exhaust streams and even directly from air is necessary to forestall climate change, lending urgency to the search for new materials that can rapidly capture CO at high capacity. The recent discovery that diamine-appended metal-organic frameworks can exhibit cooperative CO uptake via the formation of ammonium carbamate chains begs the question of whether simple organic polyamine molecules could be designed to achieve a similar switch-like behavior with even higher separation capacities. Here, we present a solid molecular triamine, 1,3,5-tris(aminomethyl)benzene (TriH), that rapidly captures large quantities of CO upon exposure to humid air to form the porous, crystalline, ammonium carbamate network solid TriH(CO)·HO (TriHCO).

Gold-Catalyzed Synthesis of (Dihydro)quinolones by Cyclization of Benzaldehyde-Tethered Ynamides and Anilines.

2-Quinolones represent a versatile class of compounds that are prevalent in natural and medicinally relevant molecules. Here we report a new approach to the selective formation of these structures. By gold catalysis, a range of benzaldehyde-tethered ynamides reacted with anilines, leading to 4-amino-3,4-dihydro-2-quinolones with high efficiency and excellent diastereoselectivity in dichloromethane.

High-performance magnesium organic batteries using renewable biomolecule-based cathode.

Rechargeable magnesium batteries (RMBs) exhibit significant potential in large-scale energy storage due to their features of high volumetric capacity, resistance to dendrite formation, and abundant magnesium resources. However, the high polarity of divalent Mg2+ ions results in sluggish diffusion kinetics in conventional inorganic cathode materials, adversely affecting reversible capacity and rate performance. Organic materials such as pyrene-4,5,9,10-tetrone (PTO) and 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA), achieve rapid and reversible intercalation of magnesium ions through carbonyl enolization, but these materials are challenged by high cost, complex preparation, and poor environmental friendliness.

CAD manipulates tumor intrinsic DHO/UBE4B/NF-κB pathway and fuels macrophage cross-talk, promoting hepatocellular carcinoma metastasis.

Background And Aims: Portal vein tumor thrombosis (PVTT), an indicator of clinical metastasis, significantly shortens hepatocellular carcinoma (HCC) patients' lifespan, and no effective treatment has been established. We aimed to illustrate mechanisms underlying PVTT formation and tumor metastasis, and identified potential targets for clinical intervention.

Approach And Results: Multi-omics data of 159 HCC patients (including 37 cases with PVTT) was analyzed to identify contributors to PVTT formation and tumor metastasis.

Objectives: To assess the prognostic impact of adequate lymphadenectomy and determine the optimal nodal assessment for different clinical stages of lung cancer.

Methods: We retrospectively reviewed 1214 patients with clinical stage I-III non-small cell lung cancer who had preoperative PET/CT and curative surgery (2006-2017). Patients were categorized based on whether they had adequate [R0] or inadequate lymphadenectomy [R(un)].

Nonmonotonous Translocation Dynamics of Highly Deformable Particles across Channels.

The translocation dynamics of cells and particles through geometric constrictions are critical in biological and biomedical processes from splenic filtration to tumor metastasis. While particle stiffness plays a key role, its role in highly nonequilibrium states remains poorly understood. Here, we present a multiscale model to investigate the impact of particle stiffness on the translocation dynamics in microfluidic channels.

Suppression of NF-κB and downstream XBP1 by DcR3 contributes to a decrease in antibody secretion.

Decoy receptor 3 (DcR3), a soluble receptor in the tumor necrosis factor receptor superfamily, regulates the functions of monocytes, macrophages, dendritic cells, and T cells. Previous studies have demonstrated that DcR3 suppresses B cell proliferation in vitro and ameliorates autoimmune diseases in animal models; however, whether and how DcR3 regulates antibody production is unclear. Using a DcR3 transgenic mouse model, we found that DcR3 impaired the T cell-dependent antigen-stimulated antibody response.

PVR exposure influences the activation, adhesion, and protein expression of human CD8+ T cells, including the CD96-mediated transfer of PVR.

Poliovirus receptor (PVR) ligands have gained attention as immunotherapy targets, yet their regulation remains unclear. Here, we examine the impact of PVR exposure on primary human CD8+ T cells. We used flow cytometry and Western blot analysis to quantify expression of PVR and its ligands in naïve and effector T cells and used adhesion assays and enzyme-linked immunosorbent assay (ELISA) to assess the impact of PVR on T cell adhesion and cytokine production.

The Outstanding Ambiphilicity of Trialkylstibines among Trialkylpnictines: Power for Stepwise Deoxygenation and N-N Coupling of Nitroarenes.

The ongoing discovery of highly reactive ambiphilic main-group species has significantly advanced the development of main-group chemistry, particularly in the realms of small molecule activation and catalysis. Theoretically, compounds featuring smaller HOMO-LUMO gaps gain stronger ambiphilicity and higher reactivity. In this work, we fundamentally demonstrate that MeSb holds the smallest HOMO-LUMO gap among trimethylpnictines, indicating its outstanding ambiphilicity.

The keyboard, a staple tool for information entry and human-machine interaction, faces demands for enhanced information security due to evolving internet technologies. This study introduces a self-powered flexible intelligent keyboard (SFIK) that harnesses the giant magnetoelastic effect to convert the mechanical pressure from key presses into electrical signals. The sensor boasts a wide sensing range (35 to 600 kPa) and a rapid response time (∼300 ms), allowing it to record and recognize individual keystroke dynamics.

Phagocytosis-driven neurodegeneration through opposing roles of an ABC transporter in neurons and phagocytes.

Lipid homeostasis is critical to neuronal survival. ATP-binding cassette A (ABCA) proteins are lipid transporters associated with neurodegenerative diseases. How ABCA transporters regulate lipid homeostasis in neurodegeneration is an outstanding question.

Shaping early neural development by timed elevated tissue oxygen tension: Insights from multiomic analysis on human cerebral organoids.

Oxygen plays a critical role in early neural development in brains, particularly before establishment of complete vasculature; however, it has seldom been investigated due to technical limitations. This study uses an in vitro human cerebral organoid model with multiomic analysis, integrating advanced microscopies and single-cell RNA sequencing, to monitor tissue oxygen tension during neural development. Results reveal a key period between weeks 4 and 6 with elevated intra-organoid oxygen tension, altered energy homeostasis, and rapid neurogenesis within the organoids.

Genetically supported targets and drug repurposing for brain aging: A systematic study in the UK Biobank.

Brain age gap (BAG), the deviation between estimated brain age and chronological age, is a promising marker of brain health. However, the genetic architecture and reliable targets for brain aging remains poorly understood. In this study, we estimate magnetic resonance imaging (MRI)-based brain age using deep learning models trained on the UK Biobank and validated with three external datasets.

Splenic red pulp macrophages eliminate the liver-resistant from the blood circulation of mice.

Invasive infections by encapsulated bacteria are the major cause of human morbidity and mortality. The liver resident macrophages, Kupffer cells, form the hepatic firewall to clear many encapsulated bacteria in the blood circulation but fail to control certain high-virulence capsule types. Here we report that the spleen is the backup immune organ to clear the liver-resistant serotypes of (pneumococcus), a leading human pathogen.

Enhanced packaging of U6 small nuclear RNA and splicing-related proteins into extracellular vesicles during HIV infection.

U6 small nuclear RNA (U6 snRNA), a critical spliceosome component primarily found in the nucleus, plays a vital role in RNA splicing. Our previous study, using the simian immunodeficiency virus (SIV) macaque model, revealed an increase of U6 snRNA in plasma extracellular vesicles (EVs) in acute retroviral infection. Given the limited understanding of U6 snRNA dynamics across cells and EVs, particularly in SIV infection, this research explores U6 snRNA trafficking and its association with splicing proteins in the nucleus, cytoplasm, and EVs.

Quantitative detection of the HVEM-BTLA checkpoint receptor cis-complex in human lymphocytes.

The herpesvirus entry mediator (HVEM) (TNFRSF14) engagement of the checkpoint inhibitory receptor B and T lymphocyte attenuator (BTLA) limits immune responses of T and B lymphocytes. HVEM and BTLA form signaling complexes in trans and when coexpressed, complexes in cis, creating a unique immune checkpoint. The function of the HVEM-BTLA cis-complex is not well understood primarily due to a lack of reagents that specifically measure the HVEM-BTLA cis-complex.

Proteasomal processing of the viral replicase ORF1 facilitates HEV-induced liver fibrosis.

Chronic infections with hepatitis E virus (HEV), especially those of genotype 3 (G3), frequently lead to liver fibrosis and cirrhosis in patients. However, the causation and mechanism of liver fibrosis triggered by chronic HEV infection remain poorly understood. Here, we found that the viral multiple-domain replicase (ORF1) undergoes unique ubiquitin-proteasomal processing leading to formation of the EV-erived MAD ctivator (HDSA), a viral polypeptide lacking putative helicase and RNA polymerase domains.

Machine-learning heat flux closure for multi-moment fluid modeling of nonlinear Landau damping.

Nonlinear plasma physics problems are usually simulated through comprehensive modeling of phase space. The extreme computational cost of such simulations has motivated the development of multi-moment fluid models. However, a major challenge has been finding a suitable fluid closure for these fluid models.

The impacts of product characteristics and regulatory environment on smokers' preferences for tobacco and alcohol: Evidence from a volumetric choice experiment.

Objective: Concurrent use of alcohol and cigarettes is well-documented in the literature. However, it is unclear how e-cigarette regulations in a growing number of localities impact the use of tobacco and alcohol in the US. This study aims to evaluate the impacts of excise taxes, tobacco use restrictions in restaurants/bars, and availability of alcohol flavor in e-cigarettes on tobacco consumption, and their cross impacts on alcohol consumption.

Stable isotopes as a predictor for organic or conventional classification of berries and vegetables.

Organic agriculture is expanding worldwide, driven by expectations of improving food quality and soil health. However, while organic certification by regulatory bodies such as the United States Department of Agriculture and the European Union confirms compliance with organic standards that prohibit synthetic chemical inputs, there is limited oversight to verify that organic practices, such as the use of authentic organic fertilizer sources, are consistently applied at the field level. This study investigated the elemental content of carbon (C) and nitrogen (N) and their stable isotopes (δ13C and δ15N) in seven different crops grown under organic or conventional practices to assess their applicability as a screening tool to verify the authenticity of organic labeled produce.
