IL-6 expression was determined by *** Combined findings from gene expression microarray analysis, bioinformatics, and population expansion validation indicated significant downregulation of the PTen gene in the high-concentration Hg exposure group. In the Hg-exposed cell model(25 and 10 μmol/L), a significant decrease in PTen expression was observed, accompanied by a significant increase in PI3K, AKT, and IL-6 ***, a low-expression cell model demonstrated that PTen gene knockdown led to a significant decrease in PTen protein expression and a substantial increase in PI3K, AKT, and IL-6 *** This is the first study to report that Hg exposure downregulates the PTen gene, activates the PI3K/AKT regulatory pathway, and increases the expression of inflammatory factors, ultimately resulting in kidney inflammation.

Insects show highly complicated adaptive and sophisticated behaviors, includ-ing spatial orientation skills, learning ability, and social interaction. These behaviors arecontrolled by the insect brain, the central part of the nervous system. The tiny insect brainconsists of millions of highly differentiated and interconnected cells forming a complexnetwork. Decades of research has gone into an understanding of which parts of the insectbrain possess particular behaviors, but exactly how they modulate these functional conse-quences needs to be clarified. Detailed description of the brain and behavior is required todecipher the complexity of cell types, as well as their connectivity and function. Single-cell RNA-sequencing (scRNA-seq) has emerged recently as a breakthrough technologyto understand the transcriptome at cellular resolution. With scRNA-seq, it is possible touncover the cellular heterogeneity of brain cells and elucidate their specific functions andstate. In this review, we first review the basic structure of insect brains and the links toinsect behaviors mainly focusing on learning and memory. Then the scRNA applicationson insect brains are introduced by representative studies. Single-cell RNA-seq has allowedresearchers to classify cell subpopulations within different insect brain regions, pinpointsingle-cell developmental trajectories, and identify gene regulatory networks. These devel-opments empower the advances in neuroscience and shed light on the intricate problemsin understanding insect brain functions and behaviors.

针对压力管道通孔型泄漏源互相关定位的声发射(acoustic emission,AE)信号降噪问题,进行了小波变换系数重构泄漏信号的最优小波基的选取工作。首先分析了管道通孔型泄漏信号的声学特性;然后使用短时傅立叶变换分析了泄漏声发射事件的发生时间,用于获得其在该时间段内的基本时域波形,同时对比基本时域波形与标准小波基的相似性删选出合适的小波基;进一步,通过分析小波变换定位泄漏声发射事件的频率分布确定最优小波基。同时考虑到声速对定位管道泄漏的影响,对管道声速进行现场测量标定。最后以最佳小波基的小波变换系数作为重构信号开展基于互相关的定位实验。实验结果表明,选择横波的波速作为管道检测的声速时,最佳小波基为“morlet”的小波变换系数作为重构信号能够很好地剔除噪声提高管道定位精度。

Copper-catalyzed enantioselective desymmetrizing C（sp2）–H functionalization of azide-ynamides via α-imino copper carbenes

Science China Chemistry 2024年第9期67卷 2982-2988页

α-Imino metal carbenes are versatile intermediates in organic synthesis, and have broad applications in the assembly of divergent N-heterocycles. However, the catalytic enantioselective desymmetrization based on α-imino metal carbenes has not been developed to date. Herein, we disclose an enantioselective desymmetrizing C（sp2）–H functionalization of azide-ynamides via α-imino copper carbenes, leading to the efficient assembly of divergent chiral indoloazepines in generally moderate to excellent yields with high enantioselectivities. Notably, this reaction represents the first enantioselective desymmetrization based on α-imino metal carbenes. Further synthetic transformations and biological tests show the potential utility of this method. Moreover,computational studies are employed to elucidate the reaction mechanism and the origin of enantioselectivity.
