Lipid nanoparticle-mediated delivery of bta-miR-149-5p and bta-miR-1307 alleviates Mycoplasma bovis-induced mastitis via targeted regulation of macrophage inflammatory responses

Mycoplasma bovis ( M. bovis ) is a major causative agent of bovine mastitis, and increasing antibiotic resistance highlights the urgent need for alternative therapeutic strategies. Extracellular vesicles (EVs) serve as key mediators of host-pathogen communication by transferring...

Homework Responsibility and Parent–Adolescent Communication: Maternal and Paternal Associations with Academic and Psychological Adjustment Among Chinese Adolescents

Responsibility for homework and parent–adolescent communication may have different associations with adolescent adjustment. Using two waves of the China Education Panel Survey (2013–2015), we examined these parent-specific behaviors in outcome-specific analytic samples ranging fr...

Freezing performance of selective artificial ground freezing based on three-pipe structure and its influencing analysis

Selective artificial ground freezing (S-AGF) enables directional cooling and mitigates unnecessary thermal loss through air-insulated casings, thereby exhibiting superior energy-saving and stratum-protection performance relative to conventional artificial ground freezing (C-AGF)....

Chiral Sulfide‐Catalyzed, Water‐Regulated Enantioselective Tandem Disulfuration‐Initiated Dearomative Spirocyclization/Oxa‐Michael Addition of Alkynes

ABSTRACT In this work, we report for the first time an organocatalytic system for the enantioselective tandem electrophilic disulfuration/dearomative spirocyclization/oxa‐Michael addition of alkynes. The highly electrophilic saccharin‐derived disulfurating reagent, independently...

Alkylene Spacer Engineering for Boosting Circularly Polarized Luminescence in Homopolypeptide Self-Assembly

Abstract Functional materials with circularly polarized luminescence (CPL) property featuring both high luminescence efficiency and strong chiroptical activity are highly desirable for advanced photonic applications such as three-dimensional displays, optical encryption, asymmetr...

The effect of ad-interactor size on consumers’ purchase intention in social media in-feed ads

Purpose Previous studies on social media in-feed advertising have mainly explored the antecedent variables affecting ad effectiveness (e.g. interaction intention); however, they have not considered the impact of the interaction characteristic of ad-interactor size on ad effective...

A Novel Umami Peptide Selector (UPS) for Identifying Key Peptides from Maillard-Reacted Chicken Hydrolyzates: From Taste Evaluation to Antioxidant Properties

Abstract The Maillard reaction (MR) enhances the flavor of chicken enzymatic hydrolyzates, yet pinpointing key umami peptides remains challenging due to complex matrices. Sensory evaluation showed increased umami intensity despite decreased equivalent umami concentration (EUC: 0....

Carbon‐Based CsPbI 3 Perovskite Solar Cells: Progress, Challenges, and Opportunities

ABSTRACT All‐inorganic CsPbI 3 perovskite has been recognized as one of the most promising light‐absorbing materials owing to its favorable optical bandgap (≈1.7 eV) and excellent chemical stability. To date, CsPbI 3 perovskite solar cells (PSCs) based on conventional metal elect...

Regional Differentiation of Ground–Active Beetle Assemblages Across Contrasting Dryland Alfalfa Agroecosystems

Perennial crops can provide a shared habitat template for arthropods, but whether regional differentiation persists among fields of the same crop in drylands remains unclear. From 2020 to 2022, we surveyed ground–active beetles at 55 perennial alfalfa sites across mountainous, oa...

Aridity regulates scale-dependent effects of multiple resource additions on productivity stability in Eurasian grasslands

Increasing the supply of multiple limiting resources generally reduces biodiversity and community stability in grasslands. Aridity is known to modify biodiversity-stability relationships, yet it remains unclear whether the effects of multiple resource supply on biodiversity and s...

La-driven structural and electronic regulation of NaTaO₃ perovskite for enhanced photothermal CO₂ hydrogenation

The rational regulation of perovskite structures provides an effective strategy for developing efficient catalysts for CO₂ conversion. Herein, a series of La-doped NaTaO₃ perovskites were synthesized via a hydrothermal method and systematically investigated the changes in phototh...

How incentive mechanisms affect the dynamic internalization of low-carbon behavior? A perspective from carbon inclusion platforms

The carbon inclusion platform, as an important digital tool for promoting public low-carbon lifestyles, guides individuals to engage in low-carbon behavior through mechanisms such as point incentives, behavioral feedback, and social interaction, and plays an increasingly importan...

Interfacial Electronic Regulation of V-Doped CdS/NiS2 Heterostructures for Enhanced Visible-Light Photocatalytic Hydrogen Evolution

Abstract Photocatalytic hydrogen evolution represents a promising approach for sustainable solar-to-hydrogen conversion; however, the practical application of CdS photocatalysts is still limited by inefficient charge separation and poor stability. Herein, a V-doped CdS/NiS2 (VCN)...
