Background: Rhizoma drynariae is a traditional Chinese medicine used in orthopedics and traumatology, but its effect on endometrial receptivity remains unknown. Aims and Objectives: To observe effect of Rhizoma drynariae and its main components on endometrial receptivity in a mus model of dysfunctional embryo implantation. Materials and Methods: mus models were established by the Gn RHa+HMG+HCG method. Normal mus receiving saline were used as controls and the remaining six groups were: model receiving saline, progynova, aspirin, Rhizoma drynariae, osteopractic total flavone, and naringin. Pinopodes in uterine endometrium were examined by scanning electron microscopy. Stem cell factor(SCF) m RNA expressions was determined by real-time RT-PCR, and estrogen receptor α(ERα), progesterone receptor(PR) by immunohistochemistry. Results: In the model group, surface morphology of endometrium was heterogeneous, without obvious pinopodes. In the Rhizoma drynaria and progynova groups, pinopodes were abundant. Compared with the blank group, model group had lower levels of SCF(-47%), ERα(-63%) and PR(-50%)(all P<0.05). In comparison, Rhizoma drynariae group had higher levels of SCF(+73%), ERα(+118%) and PR(+101%)(all P<0.01). The individual main components of Rhizoma drynariae had variable efficacy. Conclusion: Rhizoma drynariae could improve endometrial receptivity of mouse models of dysfunctional embryo implantation as shown by increased numbers of pinopodes and higher levers of SCF, ERα, PR compared with the model group.

ImSpiRE: image feature-aided spatial resolution enhancement method

Science China Life Sciences 2025年第1期 272-283页

作者： Yuwei hua Yizhi Zhang Zhenming guo Shan Bian Yong Zhang State Key Laboratory of Cardiovascular Diseases and Medical Innovation Center Institute for Regenerative MedicineDepartment of NeurosurgeryShanghai East HospitalShanghai Key Laboratory of Signaling and Disease ResearchFrontier Science Center for Stem Cell ResearchSchool of Life Sciences and TechnologyTongji University

The resolution of most spatially resolved transcriptomic technologies usually cannot attain the single-cell level, limiting their applications in biological discoveries. Here, we introduce ImSpiRE, an image feature-aided spatial resolution enhancement method for in situ capturing spatial transcriptome. Taking the information stored in histological images, ImSpiRE solves an optimal transport problem to redistribute the expression profiles of spots to construct new transcriptional profiles with enhanced resolution, together with extending the gene expression profiles into unmeasured regions. Applications to multiple datasets confirm that ImSpiRE can enhance spatial resolution to the subspot level while contributing to the discovery of tissue domains, signaling communication patterns, and spatiotemporal characterization.

在骨折的修复过程中,常发生髓内钉断骨内的情况。其主要原因是涉及肌肉影响后,髓内钉不是单钝的受压杆件,而是多种组合变形的屈曲问题。文中利用有限元法对目前较新结构的髓内钉在骨折治疗中涉及肌肉作用影响进行多方面的压、弯曲与扭转组合变形屈曲分析。得出了三叶瓣型髓内钉在涉及肌肉影响时的屈曲临界压力比单纯受压时髓内钉的屈曲临界压力小51％。并得出髓内钉只能额外承受15Nm左右的外来扭力。这些结果可供髓内钉进一步发展及临床应用参考。通过有限元的分析还可以对髓内钉受力状态的薄弱环节有一个全面的认识,为髓内钉合理设计、材料的选择等进行优化设计提供依据。

约翰·马歇尔是美国第四任首席大法官。在早期美国州权主义强势、政党纷争不已的背景下,他带领最高法院的同仁,通过对宪法文本的阐释,极大地加强了联邦权,削弱了州权,引发了州权主义者的猛烈批评。不过,马歇尔并非积极的国家主义者,他在相关案件中对州治安权的阐释及其案例判决表明,马歇尔及这一时期最高法院的大法官们都清楚地意识到,各州在其治安权的管辖范围内,依然行使着州内治理等大量政府功能,应该予以肯定和支持。实际上,联邦保有宪法列举的必要且至上的权力,而各州保留剩余的权力,联邦权与州权平衡互动,这不仅是制宪精英们的意图,也是现实的需求。

Palladium installed copper-organic framework for C–C coupling reactions

Science China Chemistry 2025年

作者： Yu-Mei Wang Mei-Xia Tao Kai-Ming Mo Xu Chen Shu-hua Zhong Elena S Shubina guo-Hong Ning Dan Li College of Chemistry and Materials Science Guangdong Provincial Key Laboratory of Supramolecular Coordination ChemistryJinan University A.N.Nesmeyanov Institute of Organoelement Compounds Russian Academy of Sciences

The formation of C–C bonds is a crucial aspect of organic synthesis. Synthesists' long-term objective is to identify novel catalysts to optimize reaction systems based on traditional transition metal catalysis. This study explores the synthesis and catalytic potential of palladium-installed covalent metal-organic frameworks(CMOFs) based on copper cyclic trinuclear units(Cu-CTUs). By incorporating palladium ions into the imine-based framework JNM-7 through a straightforward immersion method, we achieved a notable enhancement in catalytic activity for critical C–C coupling reactions, including C–H arylation and Sonogashira cross-coupling. The resulting JNM-7-Pd demonstrated remarkable stability and recyclability, maintaining its efficiency over at least three cycles without any decline in efficiency.
