miRNAs modulate altered expression of cytochrome P450s and nicotinic acetylcholine receptor subunits conferring both metabolic and target resistance to sulfoxaflor in Nilaparvate lugens (Stål).

Understanding the insecticide resistance mechanisms and their underlying regulatory pathways is essential for pest management. Previous findings indicated that the overexpression of P450 gene, CYP6ER1, was a key mechanism for sulfoxaflor metabolic resistance in Nilaparvata lugens. However, it remains unclear whether quantitative changes in the target nicotinic acetylcholine receptors (nAChRs) contribute to sulfoxaflor resistance and the underlying regulatory mechanisms involved.

Nanoparticle-enabled In Situ drug potency activation for enhanced tumor-specific therapy.

Cancer treatment faces significant challenges including inadequate tumor specificity, drug resistance, and severe side effects, often resulting in unsatisfactory patient outcomes. Nanomedicines offer a transformative platform for tumor-targeted drug delivery and antitumor potency activation, providing an indispensable strategy for overcoming the severe damage to normal tissues caused by the inherent "always-on" cytotoxicity of conventional therapeutic agents. This review focuses on the emerging concept of "nanoparticle-enabled in situ drug potency activation", where inactive or minimally toxic agents are selectively activated within tumors to enhance the therapeutic efficacy and minimize the adverse effects.

Quantum State Transfer between Superconducting Cavities via Exchange-Free Interactions.

We propose and experimentally demonstrate a novel protocol for transferring quantum states between superconducting cavities. This approach utilizes continuous two-mode squeezing interactions to generate entanglement without the exchange of any carrier photons. In contrast to the discrete operations of entanglement and Bell-state measurement in quantum teleportation, our scheme is symmetric and continuous.

Integrative multiomics analysis reveals association of gut microbiota and its metabolites with susceptibility to keloids.

Keloid scarring is a fibroproliferative disease of the skin, which can significantly impact one's quality of life through cosmetic concerns, physical discomfort (itchy; painful), restricted movement, and psychological distress. Owing to the poorly understood pathogenesis of keloids and their high recurrence rate, the efficacy of keloid treatment remains unsatisfactory, particularly in patients susceptible to multiple keloids. We conducted fecal metagenomic analyzes and both untargeted and targeted plasma metabolomics in patients with multiple keloids (MK,  = 56) and controls with normal scars (NS,  = 60); tissue-untargeted metabolomics (MK,  = 35; NS,  = 32), tissue-targeted metabolomics (MK,  = 41; NS,  = 36), and single-cell sequencing analyzes (GSE163973).

Language-specific representation of emotion-concept knowledge causally supports emotion inference.

Humans no doubt use language to communicate about their emotional experiences, but does language in turn help humans understand emotions, or is language just a vehicle of communication? This study used a form of artificial intelligence (AI) known as large language models (LLMs) to assess whether language-based representations of emotion causally contribute to the AI's ability to generate inferences about the emotional meaning of novel situations. Fourteen attributes of human emotion concept representation were found to be represented by the LLM's distinct artificial neuron populations. By manipulating these attribute-related neurons, we in turn demonstrated the role of emotion concept knowledge in generative emotion inference.
