UniMap: Type-Level Integration Enhances Biological Preservation and Interpretability in Single-Cell Annotation.

Integrating single-cell datasets from multiple studies provides a cost-effective way to build comprehensive cell atlases, granting deeper insights into cellular characteristics across diverse biological systems. However, current data integration methods struggle with interference in partially overlapping datasets and varying annotation granularities. Here, a multiselective adversarial network is introduced for the first time and present UniMap, which functions as a "discerner" to identify and exclude interfering cells from various data sources during dataset integration.

Three-Dimensional Metal-Organic Frameworks with Selectively Activated Aromatic Rings for High-Capacity and High-Rate Lithium-Ion Storage.

Metal-organic frameworks (MOFs) are considered promising candidates for anode materials in Li-ion batteries (LIBs) owing to their designable structure, abundant active sites, and well-organized porosity. However, the structural factors governing active site utilization and Li-ion storage kinetics remain inadequately understood. In particular, the Li-ion storage behaviors of aromatic rings with high LUMO energy levels and situated in varying chemical environments remain a highly debated issue.

One-step engineered mesenchymal stem cell-derived exosomes against hepatic ischemia-reperfusion injury.

Hepatic ischemia-reperfusion injury (IRI) is an important factor affecting the prognosis of patients undergoing surgery.

Mitochondria-Targeted Icaritin Nanoparticles Induce Immunogenic Cell Death in Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is a highly malignant tumor that is resistant to chemotherapy and immunotherapy. Icaritin (ICT), a traditional Chinese medicine, has been reported as an immunoregulatory agent for treating advanced unresectable HCC. ICT induces mitophagy to cause immunogenic cell death (ICD); however, the poor bioavailability of ICT limits its therapeutic efficacy and clinical use.

Formation mechanism of lignin-derived carbon quantum dots: From chemical structures to fluorescent behaviors.

Biomass-derived carbon quantum dots (CQDs) have the advantage of being green and low-cost, but their complex structure makes the study of their formation mechanism encounter a bottleneck. Lignin-derived CQDs were prepared by a two-step process of "low-temperature liquid depolymerization" coupled with "hydrothermal reaction" in a mild organic acid system. In the first step of the low-temperature acidolysis process, the lignin polymer first undergoes deethering and depolymerization reactions.

Mechanical Characteristics of Multi-Level 3D-Printed Silicone Foams.

Three-dimensional-printed silicone rubber foams, with their designable and highly ordered pore structures, have shown exceptional potential for engineering applications, particularly in areas requiring energy absorption and cushioning. However, optimizing the mechanical properties of these foams through structural design remains a significant challenge. This study addresses this challenge by formulating the research question: How do different 3D-printed topologies and printing parameters affect the mechanical properties of silicone rubber foams, and how can we design a novel topological structure? To answer this, we explored the mechanical behavior of two common structures-simple cubic (SC) and face-centered tetragonal (FCT)-by varying printing parameters such as filament spacing, filament diameter, and layer height.

[Recent advances in metabolic engineering of microorganisms for production of tyrosol and its derivatives].

Tyrosol is a natural phenolic compound with antioxidant, anti-inflammatory and other biological activities, serving as an important precursor of high-value products such as hydroxytyrosol and salidroside. Therefore, the green and efficient biosynthesis of tyrosol and its derivatives has become a research hotspot in recent years. Building cell factories by metabolic engineering of microorganisms is a potential industrial production way, which has low costs and environmental friendliness.

In-situ construction of integrated asymmetric micro-supercapacitors achieving monolithic hundred-volt output.

Asymmetric micro-supercapacitors (MSCs) exhibit higher energy density while face significant challenges in power density as well as cycling life and large dimensions. The key factors contributing to these dilemmas include the match of electrode materials and electrolytes, poor uniformity of device, and complicated while low-precise fabrication processes. Herein we develop a laser scribing-engraving (LSE) strategy to fabricate MSCs with monolithic high-voltage output and scalable array integration.

Evaluation of enhanced external counterpulsation for diabetic foot based on a patient-specific 0D-1D cardiovascular system model.

Background And Objective: Diabetic foot (DF) complications often lead to severe vascular issues. This study investigated the effectiveness of enhanced external counterpulsation (EECP) and its derived innovative compression strategies in addressing poor perfusion in DF. Although developing non-invasive and efficient treatment methods for DF is critical, the hemodynamic alterations during EECP remain underexplored despite promising outcomes in microcirculation.

The alarmin IL-33 exacerbates pulmonary inflammation and immune dysfunction in SARS-CoV-2 infection.

Dysregulated host immune responses contribute to disease severity and worsened prognosis in COVID-19 infection and the underlying mechanisms are not fully understood. In this study, we observed that IL-33, a damage-associated molecular pattern molecule, is significantly increased in COVID-19 patients and in SARS-CoV-2-infected mice. Using IL-33 mice, we demonstrated that IL-33 deficiency resulted in significant decreases in bodyweight loss, tissue viral burdens, and lung pathology.

Tirzepatide modulates the regulation of adipocyte nutrient metabolism through long-acting activation of the GIP receptor.

Tirzepatide, a glucose-dependent insulinotropic polypeptide/glucagon-like peptide 1 receptor (GIPR/GLP-1R) agonist, has, in clinical trials, demonstrated greater reductions in glucose, body weight, and triglyceride levels compared with selective GLP-1R agonists in people with type 2 diabetes (T2D). However, cellular mechanisms by which GIPR agonism may contribute to these improved efficacy outcomes have not been fully defined. Using human adipocyte and mouse models, we investigated how long-acting GIPR agonists regulate fasted and fed adipocyte functions.

Innate and Adaptive Immune Parameters following mRNA Vaccination in Mice.

The COVID-19 pandemic has raised the standard regarding the current vaccine development pace, as several messenger RNA (mRNA)-lipid nanoparticle (LNP) vaccines have proved their ability to induce strong immunogenicity and protective efficacy. We developed 1-methylpseudouridine-containing mRNA-LNP vaccines, expressing either the more conserved SARS-CoV-2 nucleoprotein (mRNA-N) or spike protein (mRNA-S), both based on the prototypic viral sequences. When combining both mRNA-S and mRNA-N together (mRNA-S+N), the vaccine showed high immunogenicity and broad protection against different SARS-CoV-2 variants, including wildtype, Delta, BA.

Nonlinear Conductivity and Thermal Stability of Anti-Corona Epoxy Resin Nanocomposites.

The long-term operation of motors induces substantial alterations in the surface conductivity and nonlinear coefficient of anti-corona paint, diminishing its efficacy and jeopardizing the longevity of large motors. Hence, the development of high-performance anti-corona paint holds paramount importance in ensuring motor safety.
