The lack of an effective gene editing technology system for Fraxinus mandshurica makes it challenging to improve its traits through genetic engineering methods. In this study, an effective CRISPR/Cas9 gene editing system targeting plant growth points was established through the optimization of Agrobacterium tumefaciens concentration and infection duration. Furthermore, a tissue culture system for clustered buds was developed by supplementing the media with hormones at different concentrations.

Tumor heterogeneity and the dynamic evolution of tumor immune microenvironment (TIME) contribute to therapeutic resistance and poor clinical prognosis. To elucidate this mechanism, we first established a murine tumor evolution model (TEM) and systematically identified evolutionary core genes demonstrating progressive alterations during evolution. Subsequently, we developed a single-cell TEM through integrative analysis of hepatocellular carcinoma (HCC) clinical specimens (n=10) with external cohorts (n=11), enabling dynamic characterization of tumor-immune interactions during evolution, while addressing ethical challenges associated with obtaining tumor tissues from multiple stages in a single patient.

The immunosuppressive niche of the breast cancer microenvironment and the vascular basement membrane significantly hinder the efficacy of nanoparticle-based antitumor immunotherapy delivered via the vascular system. This study describes the design of a puncture-delivered tumor implant, utilizing a photo-cross-linked gelatin methacryloyl hydrogel as the matrix, loaded with CuMnO nanoparticles (CMO NPs) and monomethyl fumarate (MMF), enabling the sustained release of nanoparticles through matrix metalloproteinase-responsive degradation. Mechanistically, CMO NPs induce cuproptosis and immunogenic cell death (ICD) in tumor cells, while synergizing with MMF to trigger substantial mtDNA release into the cytosol.

Deubiquitinating modification of proteins is involved in the pathogenesis of diseases. Here, we investigated the role and regulating mechanism of a deubiquitinating enzyme (DUB), ovarian tumor domain-containing protein 1 (OTUD1), in diabetic cardiomyopathy (DCM). We find a significantly increased OTUD1 expression in diabetic mouse hearts, and single-cell RNA sequencing shows OTUD1 mainly distributing in cardiomyocytes.

The potential of milk Fourier-transform mid-infrared (FTIR) spectroscopy in predicting cow fertility has been extensively examined, but largely based on the number of services per conception (NSC). Compared with NSC, Calving-to-conception interval (CCI) may be a more critical factor influencing the profitability, productivity, and sustainability of dairy herds, as it reflects days to first breeding, voluntary waiting period, NSC, and service intervals. Our objectives were to evaluate the ability of FTIR spectroscopy and farm data collected from early lactation to predict CCI length postcalving in Holstein cows from a highly productive TMR system.

Acute pancreatitis (AP) is a common abdominal inflammatory disease, characterized by pancreatic autodigestion, acinar cell necrosis, and systemic inflammation. Currently, there is a lack of specific drugs in the treatment of AP. Traditional Chinese medicine (TCM) is an effective approach in the prevention and treatment of AP, with rheum being one of the key components in commonly used TCM formulas for treating AP.

Pathological images are crucial for tumor diagnosis; however, due to their extremely high resolution, pathologists often spend considerable time and effort analyzing them. Moreover, diagnostic outcomes can be significantly influenced by subjective judgment. With the rapid advancement of artificial intelligence technologies, deep learning models offer new possibilities for pathological image diagnostics, enabling pathologists to diagnose more quickly, accurately, and reliably, thereby improving work efficiency.

This study presents a Python-based tool for extracting molecular reaction pathways from kinetic simulation trajectory files. Compared to traditional depth first search (DFS) and breadth first search (BFS) algorithms, a more efficient chain analysis algorithm is introduced. The tool utilizes a full-time domain response analysis approach, enabling the identification of reactions across nonadjacent frames, thereby enhancing the comprehensiveness of the analysis.

Thermally enhanced upconversion luminescence demonstrates distinct advantages for optical thermometry in complex scenarios. In this work, NaYS:Tm phosphors are synthesized via a solid-gas reaction method, followed by systematic investigation of the upconversion luminescence characteristic. The abundant energy level structure of Tm enables its dual functionality as both sensitizer and activator, achieving self-sensitized upconversion luminescence.

Drug-induced sleep endoscopy (DISE) is a dynamic diagnostic tool that is increasingly used to evaluate upper airway obstruction, especially in pediatric obstructive sleep apnea. Although initially established in adult populations, its pediatric application is expanding. Since 1990, more than 80 studies have explored various aspects of DISE, with a growing subset focusing specifically on its use in children, supported by advancements in sedation protocols.

Plant-specific GRAS transcription factors play crucial roles in the response to abiotic stresses, yet many of GRASs remain functionally uncharacterized. In this study, the GRAS transcription factor BpGRAS34 from Betula platyphylla was identified and characterized for its role in responding to salt stress. BpGRAS34 is a nuclear-localized protein that possesses transcriptional activation activity.

Unlabelled: Vaccine preventable diseases remain the leading causes of death among children in Sub-Saharan Africa.

Background/objectives: As vaccines provide the best possible protection only when all required doses are received, it is essential to understand how the published literature is designed and conducted regarding the completion of recommended childhood vaccine series for children aged 12-23 months in SSA.

Methods: A comprehensive search was conducted across five databases (PubMed, Embase, CINAHL, Web of Science, and Google Scholar) to identify the relevant literature published between January 2000 through December 2023.

To investigate the prevalence and pathogenic characteristics of avian reovirus (ARV) in the Xinjiang region of China, this study collected suspected joint tissue samples from broiler farms across different areas of the Taikun Group. The samples were subjected to virus isolation, RT-PCR analysis, sequence analysis, in vitro replication assays, and pathogenicity assessments in specific pathogen-free (SPF) chicken embryos and chickens. The results revealed the isolation of a chicken-derived ARV epidemic strain, designated as ARV xj-1.

While deep neural networks (NNs) significantly advance image compressed sensing (CS) by improving reconstruction quality, the necessity of training current CS NNs from scratch constrains their effectiveness and hampers rapid deployment. Although recent methods utilize pre-trained diffusion models for image reconstruction, they struggle with slow inference and restricted adaptability to CS. To tackle these challenges, this paper proposes Invertible Diffusion Models (IDM), a novel efficient, end-to-end diffusion-based CS method.

Epoxy resins are critical materials in aerospace applications, yet their mechanical properties, specifically the tensile modulus, can be significantly compromised when exposed to electron irradiation in space environments. To thoroughly examine this degradation, we developed an integrated research approach combining vacuum electron irradiation experiments with multi-scale simulations. Coarse-grained (CG) and Monte Carlo (MC) methods were employed to generate the necessary models and primary knock-on atom (PKA) data, while molecular dynamics (MD) simulations were conducted to model the irradiation and tensile processes.
