Multi-bioactivity of sesquiterpenes from Zanthoxylum piasezkii: contact toxicity, repellent and antifeedant effects against Tribolium castaneum via odorant receptor modulation

Plant-derived secondary metabolites, particularly monoterpenes and sesquiterpenes, have been proven effective for controlling stored-product pests. However, their application has been limited because their mechanisms of action remain unclear. In this work, three sesquiterpenes we...

ADSCs-Exo Attenuate HIRI in Miniature Pigs: Pharmacological Evidence for a Potential Association Between Copper-Associated Alterations and Ferroptosis-Related Responses

Hepatic ischemia–reperfusion injury (HIRI) involves multiple forms of regulated cell death, but the relationship between copper-associated alterations and ferroptosis-related responses remains incompletely understood. This study investigated whether pharmacological modulation of...

Biological Control of Bradysia odoriphaga Using Coenosia attenuata with Banker Media System and Mulch Layer

Greenhouse cage trials were conducted to evaluate the biocontrol potential of the predatory tiger fly Coenosia attenuata against the Chinese chive maggot Bradysia odoriphaga infesting Allium tuberosum. To ensure that adult C. attenuata have sufficient food when the B. odoriphaga...

Stable Continuum-Valued Observables from Finite Refinement Measurements: The RCS Framework and Its Physical Spectrum

This preprint develops a refinement–compatibility–stability (RCS) framework in which finite process occurrences generate rational calibration readouts indexed by a directed refinement system, and studies when such readouts determine a stable continuum value. Throughout, a continu...

Stable Continuum-Valued Observables from Finite Refinement Measurements: The RCS Framework and Its Physical Spectrum

This preprint develops a refinement–compatibility–stability (RCS) framework in which finite process occurrences generate rational calibration readouts indexed by a directed refinement system, and studies when such readouts determine a stable continuum value. Main results. Every s...

Fulvic acid: a novel biofilm denitrification enhancer

To address the challenges of prolonged start-up cycles and poor operational stability in biofilm reactors for treating high ammonia nitrogen pollution in aquaculture effluent, this study adopted fulvic acid (FA) as a novel biofilm enhancer to systematically analyze its regulatory...

Non-contact yak estrus detection using ocular thermal infrared images and an attention-enhanced DenseNet model

Yak estrus detection in plateau pastoral areas still relies on inefficient manual observation and contact-based devices with limited adaptability, which restricts the development of intelligent breeding systems. This study proposes a non-contact estrus detection method based on o...

Genome-Wide Identification of the CmABF Gene Family in Melon (Cucumis melo L.) and Their Response to Ozone and ABA

Melon (Cucumis melo L.) is a globally significant horticultural crop whose fruit quality and postharvest shelf life are profoundly influenced by oxidative stress. Abscisic acid (ABA)-responsive element binding factors (ABFs), which represent the Group A subfamily of the basic leu...

Sanxan–Whey Protein Isolate Composite-Fabricated Pickering HIPEs: Synergistic Stabilization, Environmental Tolerance and Enhanced Curcumin Bioaccessibility

Traditional high internal phase emulsions (HIPEs) require high protein dosage and exhibit poor thermal-saline tolerance, limiting their application as clean-label food carriers for lipophilic nutrients. Sanxan (SAN) possesses unique gelling and emulsifying properties, while its a...

StuPPO9 Enhances Drought Tolerance in Potato (Solanum tuberosum) by Coordinating Photosynthetic Stability and Secondary Metabolism Reprogramming

Drought stress is a primary abiotic constraint limiting potato productivity. While polyphenol oxidase (PPO) is known to participate in stress responses, the specific role of StuPPO9 in drought tolerance remains poorly understood. In this study, we generated StuPPO9-overexpressing...

Observation–Feedback Closure I (v1.5.0): A Self-Consistent Relational Reconstruction from Directed Processes and Internal Occurrence Arithmetic to Functional Dimensionality and Conditional Geometric, Temporal, and Topological Extensions

This preprint is version v1.5.0 of Observation–Feedback Closure I. It presents a foundational reconstruction and logical restructuring of the OF Closure framework rather than a merely additive extension of v1.4.0. The principal purpose of this version is to repair three foundatio...

Aerobic Denitrification Reactor with Pseudomonas chloritidismutans K14 Improves Water Quality and Growth of Hybrid Grouper (Epinephelus fuscoguttatus ♀ × Epinephelus lanceolatus ♂) in RAS

The intensification of mariculture has increased nitrogen and phosphorus pollution in aquaculture wastewater. Conventional treatments often prove inefficient under saline conditions. To address this challenge, we developed an innovative aerobic denitrification reactor using Pseud...

Gill histological, biochemical and transcriptomic responses of Coregonus ussuriensis to acute salinity stress

Salinity is a key environmental factor affecting the osmoregulation and physiological homeostasis in freshwater fish. Juvenile Coregonus ussuriensis has been considered a candidate species for culture in moderately saline waters, but its short-term physiological and molecular res...
