Transcriptome profiling analysis of heat-adapted and heat-sensitive breeder hen jejunal mucosal tissues in response to acute heat stress

<title>Abstract</title> Background Heat stress impairs intestinal integrity in poultry, compromising nutrient digestion and absorption. Nevertheless, the individual variation in heat tolerance suggests distinct molecular responses that are still not well understood. Materials and...

Transcriptome Reversal in Sulfate Transporter Involves Abiotic Stress in Sesuvium portulacastrum L.

Sulfur is an essential nutrient involved in plant growth, redox regulation, and responses to environmental stresses. Sulfate transporters (SULTRs) control sulfate uptake and distribution, thereby affecting sulfur availability for metabolic processes and stress adaptation. However...

A knowledge tracing model based on heterogeneous exercise graphs and multi-source behavioral feature fusion in blended learning environments

With the widespread adoption of blended learning, learner data have evolved from single response sequences to multi-source heterogeneous behaviors spanning pre-class preparation and in-class interaction. This poses new challenges for traditional knowledge tracing methods in model...

Two Earliest Optical-UV Tidal Disruption Events Hidden in the SDSS DR7 Catalog Unveiled by the Transformer-based Spectrum Classifier

Abstract Optical spectroscopic features are decisive in the current identification of optical-UV tidal disruption events (TDEs). Regarding that the TDE estimated occurrence rate is 10 −5 –10 −4 galaxy −1 yr −1 by both theoretical and observational methods, large optical spectrosc...

Novel N -PhenylphthalimideDerivatives as Protoporphyrinogen IX Oxidase-Targeted Inhibitor Herbicides

Abstract The use of herbicides represents one of the effective weed management strategies. To create high-efficiency, low-risk protoporphyrinogen IX oxidase (PPO)-targeted herbicides, a set of novel N-phenylphthalimides bearing 1,3,4-oxadiazole and acylhydrazide fragments was des...

NIR-activated NO-propelled nanomotors for deep tumor penetration and DNA-repair sensitized photothermal therapy of prostate cancer

Photothermal therapy (PTT) for solid prostate cancer (PCa) is often limited by poor intratumoral penetration and rapid DNA repair. Herein, we engineered a PSMA-targeted gas nanomotor that couple deep tumor penetration with DNA repair sensitization for enhanced photothermal/NO the...

Design, synthesis, and biological activity studies of formononetin derivatives containing pyrazole amide moieties

Abstract BACKGROUND Global food security faces dual challenges from pathogen threats and increasing fungicide resistance, urgently necessitating the development of new pesticides that are efficient, low‐toxicity, and environmentally friendly. Natural products, owing to their stru...

Multimodal BERT exploration of uncertain project resilience evolution via textual and log data joint modeling

To address the need for dynamic project resilience evaluation under uncertainty and the difficulty of jointly modeling risk texts and execution logs, this study proposes a Multimodal-BERT joint modeling framework for analyzing project resilience evolution. The framework combines...

Objective–Subjective Socioeconomic Status Configurations, Self-Acceptance, and Adolescent Prosocial Moral Reasoning: A Response Surface Analysis

Background: Objective and subjective socioeconomic status capture distinct aspects of adolescents’ socioeconomic experience, but their joint associations with prosocial moral reasoning and self-acceptance remain unclear. This study examined objective–subjective socioeconomic stat...

Effects of monensin residues on microbial community and the attenuation of antibiotic resistance genes during chicken manure composting

Monensin is a polyether ionophore antibiotic widely used to prevent coccidiosis and inhibit Gram-positive bacteria. Composting is widely regarded as an effective strategy for reducing the abundance of antibiotic resistance genes (ARGs) in manure. However, the long half-life of mo...

Substrate-AssistedRedox-Neutral Formal [4 + 3] Annulationof Alkynyl Aldehydes with 9,10-Phenanthrenequinones via N-HeterocyclicCarbene Catalysis

Abstract Medium-sized oxygen-containing heterocycles are important structural motifs in natural products and functional molecules, yet their efficient synthesis remains challenging. Herein, we disclose a N-heterocyclic carbene (NHC)-catalyzed redox-neutral formal [4 + 3] annulati...

Damage evolution of coal under SHPB impact and multi-scale simulation

As energy exploitation advances, operations are increasingly moving into deep coal seam regions. Understanding the dynamic mechanical properties of coal seams under complex stress conditions in such deep-seated environments has become a key focus in mining engineering. In this st...

Capturing microclimates: 30-m downscaled climate dataset reveals fine-scale suitability patterns of invasive pests in karst landscapes

Karst landscapes are characterized by extreme topographic heterogeneity, which limits the capacity of conventional coarse-resolution climate data to resolve local microclimates, thereby introducing uncertainty into biological invasion risk assessments. This study developed a high...
