Preparation Method of Simulated Deep Sandstone Materials Based on Dual Equivalence of Principal Components and Mechanical Properties, and Quantitative Evaluation of Simulation Effectiveness

Intact deep sandstone cores are scarce, heterogeneous with poorly repeatable, limiting systematic laboratory studies of deep-rock mechanical behavior. This study selected dense sandstone recovered from 1050 m in the Pingdingshan mining area as the prototype system for the develop...

Targeted uterine artery infusion of bone marrow-derived mesenchymal stem cells for severe intrauterine adhesions: a randomized controlled trial with exploratory translational analyses

Severe intrauterine adhesions (IUA) represent a profound failure of endometrial regeneration, characterized by excessive fibrosis and vascular insufficiency. Mesenchymal stem cell-based therapies show regenerative potential, but clinical evidence is inconsistent, and optimal deli...

Optimized Molecular Nucleation Behaviors in Highly Efficient Organic Solar Cells Enabled by a Bezothiophene-Based Solid Additive

As the most critical component of organic solar cells (OSCs), the morphology of the active layer directly dictates the photovoltaic performance of the devices. Recent studies have demonstrated that tailoring the active layer morphology using solid additives is a facile and effect...

Roles of cerebrospinal fluid metabolites in neuromyelitis optica spectrum disorder: Insights from Mendelian randomization

Neuromyelitis optica spectrum disorder (NMOSD) is a rare multifocal inflammatory disease that primarily affects the optic nerve and spinal cord, leading to visual loss and paralysis. Although current research has identified numerous biomarker changes in the cerebrospinal fluid (C...

A total infectome framework for resolving complex disease etiology in aquaculture

Traditional pathogen isolation can establish disease causality but often fails in complex infections involving unknown or multiple microbial backgrounds, whereas metatranscriptomics comprehensively captures the total infectome without directly resolving the primary etiological ag...

Matrix Stiffness-Encoded Mechanical Memory Maintains Proliferative Dominance in Metastatic Tumors

Primary and metastatic lesions share similar biological properties despite existing in different microenvironments. A better understanding of the mechanisms underlying the maintenance of phenotypic homogeneity in heterogeneous microenvironments could help identify strategies for...

U-Shaped Association Between Left Ventricular Dimension and Mortality in Patients With Heart Failure

Importance Left ventricular structural assessment is fundamental in heart failure (HF). However, the independent prognostic value of left ventricular size beyond its association with ejection fraction remains poorly defined in real-world, large-scale populations. Objective To inv...

Intravenous Administration of Stromal Vascular Fraction Attenuates Early Busulfan-Induced Testicular Injury in Rats: An Alternative Cell-Based Approach for Spermatogenic Impairment

Stromal vascular fraction (SVF), an uncultured adipose-derived cell population, exerts regenerative effects primarily through paracrine mechanisms. While local intratesticular injection of SVF alleviates busulfan-induced testicular injury, the intravenous route remains unexplored...

p38β-mediated BiP phosphorylation drives stemness and chemoresistance by suppressing UPR activation in hepatocellular carcinoma

Abstract Tumor-initiating cells (TICs) promote tumor initiation and therapy resistance, yet the kinase regulators that sustain TICs remain incompletely defined. Here, we identify the stress kinase p38β (MAPK11) supports TIC maintenance and drug resistance in hepatocellular carcin...

Multi-Agent Reinforcement Learning Game Model for Market Economic Equilibrium Regulation

Market equilibrium regulation constitutes a dynamic decision-making problem on complex networks, where strategic firms, consumers, platforms, and regulators interact under uncertain demand, delayed price information, and networked spillovers. Although existing multi-agent reinfor...

Time-dependent anti-Müllerian hormone dynamics during GnRHa-based endocrine therapy in young breast cancer survivors: a longitudinal real-world cohort study

Abstract Background Anti-Müllerian hormone (AMH) is widely used to assess ovarian reserve in young women with breast cancer. However, its interpretation during gonadotropin-releasing hormone agonist (GnRHa)-based endocrine therapy remains challenging because pharmacologic ovarian...

Numerical translations and labor conditions in China’s honey supply chain

Building on Tsing’s concept of salvage accumulation, which theorized capitalism as profiting without controlling commodity production, this paper takes Chinese apiculture – characterized by vertical integration – as a case study to examine how translation processes are performed...

From intravascular imaging to adaptive vascular care: intelligent photonics and digital twins in panvascular disease

Panvascular diseases (PVDs) stand as the leading cause of global mortality, necessitating a paradigm shift from local anatomical repair to the systemic restoration of vascular homeostasis. While intravascular optical imaging has revolutionized diagnosis, it remains a passive obse...

Machine learning prediction model of transition from acute kidney injury to acute kidney disease after liver transplantation: a retrospective study

The transition from acute kidney injury (AKI) to acute kidney disease (AKD) is a frequent sequela after liver transplantation (LT), associated with increased short-term mortality, prolonged hospitalization, and increased likelihood of progression to chronic kidney disease. Early...

Benzothiazole derivatives target oligoadenylate synthetase and enhance RSV vaccine efficacy as adjuvants

2′,5’ oligoadenylate (2-5A) activates RNase L to degrade intracellular RNA and inhibit viral proliferation. The resulting nucleotide fragments bind RIG-I-like receptors to initiate type I interferon (IFN-I) signaling, enhancing maturation of antigen processing cells to trigger ad...

Wood-Inspired Bioadaptable Material with Neurite Outgrowth Guidance Structures, Superior Cell Microenvironment, and Long-Term Structural Stability

Abstract Nerve injuries present serious clinical challenges worldwide. Autologous nerve transplantation is recognized as the gold standard to treat long-gap peripheral nerve defects, but its application has inherent limitations. This situation highlights the need for innovative r...

Plastome convergence across endoparasitic plant lineages: genome reduction, high AT bias, elevated substitution rates, and functional persistence in Mitrastemon yamamotoi

In heterotrophic plants, the loss of photosynthesis is often associated with plastid genome (ptDNA) reduction, although the extent of genome decay varies widely among lineages and may culminate in complete genome loss. Of the multiple transitions to heterotrophy among angiosperms...

Artificial intelligence empowers full-stack histopathological diagnosis and prognosis of renal cell tumor: a multi-center study with external validation

BACKGROUND: The rapid advancement of digital pathology has opened unprecedented opportunities for intelligent diagnosis in renal cell tumor. However, there remains a significant gap in the availability of reliable deep learning models capable of comprehensive kidney cancer detect...

Single-cell atlas of reproductive endocrine organs reveals transcriptomic responses to type 1 diabetes mellitus in nonhuman primates

Abstract Type 1 diabetes mellitus characterized by insulin deficiency and hyperglycemia is associated with female subfertility. However, how hyperglycemia affects the hypothalamic-pituitary-ovarian-uterine axis remains poorly understood. In this study, we performed single-cell tr...

SLC25A12 mitigates mitochondrial dysfunction in myoblast senescence, and alleviates cuproptosis-related changes under copper stress
