Photocatalytic asymmetric C-C coupling for CO reduction on dynamically reconstructed Ru-O/Ru-O sites.

Solar-driven CO reduction to value-added C chemicals is thermodynamically challenging due to multiple complicated steps. The design of active sites and structures for photocatalysts is necessary to improve solar energy efficiency. In this work, atomically dispersed Ru-O sites in RuInO are constructed by interior lattice anchoring of Ru.

Immune Response Elicited by Recombinant Adenovirus-Delivered Glycoprotein B and Nucleocapsid Protein UL18 and UL25 of HSV-1 in Mice.

Due to the complex pathogenic and immune escape mechanisms of herpes simplex virus type 1 (HSV-1), especially the failure of induced immune responses to block the initial cell-to-cell transmission of the virus from skin cells to neurons, the body struggles to establish effective prevention and control methods, resulting in the failure of currently developed vaccines. Previous studies have highlighted the crucial roles of surface glycoproteins and nucleocapsid proteins in activating the body's immune defense system against HSV-1 infection. In this study, recombinant adenoviruses were used as vectors to generate adenoviruses carrying the nucleocapsid protein genes UL18 and UL25, as well as the surface glycoprotein gene gB.

A chromosome-scale reference genome of the Banna miniature inbred pig.

The Banna miniature inbred pig (BN) is an intensively inbred line for biomedical research and xenotransplantation due to its low individual variation and stable genetic background. Although it is originated from the Diannan miniature pig (DN), substantial genetic changes have actually occurred. However, the lack of a BN reference genome has limited studies on the complete genomic architecture and utilization as a biomedical model.

Background: Colorectal cancer (CRC) is an aggressive malignancy among malignant tumours, with a high incidence globally. LINC01614, a long non-coding RNA, has been identified as an essential regulator in multiple cancer types. However, its biological functions and underlying molecular mechanisms in CRC remain largely unknown.

tRNA methyltransferase DNMT2 promotes hepatocellular carcinoma progression and enhances Bortezomib resistance through inhibiting TNFSF10.

The tRNA methyltransferase DNMT2 (TRDMT1) plays a crucial role in various biological functions; however, its role in cancer, particularly in liver cancer, remains incompletely understood. In this study, we demonstrate that high DNMT2 expression is negatively correlated with prognosis in clinical liver cancer patients. A series of in vitro and in vivo experiments showed that DNMT2 promotes the proliferation, colony formation, and metastasis of hepatocellular carcinoma cells.

Novel chitosan/lignin hydrogel prepared by the Mannich reaction for Pb(II) and Cu(II) removal from aqueous solution.

Green and high-performance biomass-based adsorbents have a good application prospect for the removal of heavy metals. At present, the preparation of chitosan/lignin biomass adsorbents mainly adopts dissolution-drying method, and the obtained adsorbents show relatively poor adsorption performance for heavy metals. To overcome this problem, a novel chitosan/lignin hydrogel (CSL) is prepared by a simple one-pot method through the Mannich reaction.

Docosahexaenoic acid protects against ischemic stroke in diabetic mice by inhibiting inflammatory responses and apoptosis.

This study was to explore whether docosahexaenoic acid (DHA) protects against ischemic stroke in diabetic mice and its mechanisms. DHA was administered to mice and its effects on stroke outcomes in type 1 diabetes mellitus were assessed 24 h and 3 days post-reperfusion using RNA sequencing, flow cytometry, multiplex immunoassays, and western-blotting analysis. In diabetic mice, DHA administration post-ischemic stroke significantly reduced cerebral infarct size, brain edema, and neurological impairments.

Ischemic Postconditioning Regulates New Cell Death Mechanisms in Stroke: Disulfidptosis.

Background And Objective: Stroke poses a critical health issue without effective neuroprotection. We explore ischemic postconditioning's (IPostC) potential to mitigate stroke-induced brain injury, focusing on its interaction with disulfidptosis, a novel cell death pathway marked by protein disulfide accumulation. We aim to clarify IPostC's protective mechanisms against stroke through gene sequencing and experimental analysis in mice.

A multi-feature fusion graph attention network for decoding motor imagery intention in spinal cord injury patients.

Electroencephalogram (EEG) signals exhibit temporal-frequency-spatial multi-domain feature, and due to the nonplanar nature of the brain surface, the electrode distributions follow non-Euclidean topology. To fully resolve the EEG signals, this study proposes a temporal-frequency-spatial multi-domain feature fusion graph attention network (GAT) for motor imagery (MI) intention recognition in spinal cord injury (SCI) patients.The proposed model uses phase-locked value (PLV) to extract spatial phase connectivity information between EEG channels and continuous wavelet transform to extract valid EEG information in the time-frequency domain.

Stroke-Induced Renal Dysfunction: Underlying Mechanisms and Challenges of the Brain-Kidney Axis.

Stroke, a major neurological disorder and a leading cause of disability and death, often inflicts damage upon other organs, particularly the kidneys. While chronic kidney disease (CKD) has long been established as a significant risk factor for cerebrovascular disease, stroke can induce renal dysfunction, manifesting as acute kidney injury (AKI) or CKD. Mounting clinical and basic research evidence supports the existence of a bidirectional brain-kidney crosstalk following stroke, implicating specific mechanisms and pathways in stroke-related renal dysfunction.

Cytokine profile of cerebrospinal fluid in pediatric patients with metastatic medulloblastoma.

Background: Medulloblastoma (MB) is a malignant pediatric central nervous system tumor that is prone to leptomeningeal metastasis. Currently, apart from magnetic resonance imaging and cerebrospinal fluid (CSF) cytology, there are no reliable biomarkers for MB progression. Cytokines are key proteins in signaling pathways in the tumor microenvironment and are closely related to tumor recurrence and progression.

Methyl-β-cyclodextrin Enhances Tumor Cellular Uptake and Accumulation of α-Linolenic Acid-Paclitaxel Conjugate Nanoparticles.

Improving nanomedicine uptake by tumor cells is key to achieving intracellular drug delivery. In this study, we found that methyl-β-cyclodextrin (MβCD) can significantly promote the intracellular accumulation of nanoparticulated α-linolenic acid-paclitaxel conjugates (ALA-PTX NPs) via enhanced clathrin-mediated endocytosis and limited degradation in lysosomes. Our in vitro results indicated that MβCD not only reduced the plasma membrane cholesterol content and increased plasma membrane fluidity, leading to ALA-PTX NPs being more easily incorporated into the plasma membrane, further enhancing membrane fluidity and making the plasma membrane more susceptible to tensile deformation, forming intracellular vesicles to enhance ALA-PTX NP cellular uptake, but also destroyed lysosomes and then limited ALA-PTX NPs' degradation in lysosomes.
