pKa engineering of a near‐infrared fluorescent probe for sensitive imaging of oxidative stress in atherosclerotic plaques

Qianqian Yu, Jiahui Liang, Tijian Zhou, Qiaomeng Chen et autres

Abstract Reactive oxygen species (ROS) are key mediators in the progression of atherosclerosis, making ROS imaging valuable for evaluating oxidative stress in plaques. However, most activatable fluorescent probes show limited fluorescence enhancement under physiological conditions because their fluorophores are insufficiently ionized at …

APTES-Assisted In Situ Growth of CsPbBr3 in PVDF Nanofibers via Interfacial Ionic-Dipole Interactions for Enhanced Piezoelectric Performance

Yanan Li, Haijun Wang, Qianqian Yu, Yilin Chen et autres

Abstract Poly(vinylidene fluoride) (PVDF)-based piezoelectric materials are commonly constrained by low polar-phase content. Here, we report an APTES-assisted in situ crystallization strategy to fabricate PVDF/APTES@CsPbBr3 nanocomposites. APTES acts as a bifunctional linker that passivates CsPbBr3 quantum dot surfaces while introducing protonated ammonium …

SIZ1‐Mediated SUMOylation of LBD29 Recruits ARF7 to Fine‐Tune Auxin Signaling in Lateral Root Development

Jiaxuan Sui, Qianlan Yin, Yiying Chen, Liping Zhang et autres

Auxin signaling orchestrates plant development through TRANSPORT INHIBITOR RESPONSE 1 (TIR1)/AUXIN-SIGNALING F-BOXs (AFBs)-dependent nuclear auxin signaling pathway and emerging posttranslational modification (PTM) mechanisms. Here, we identify Small Ubiquitin-like Modifier (SUMO) E3 ligase SAP AND MIZ1 DOMAIN-CONTAINING LIGASE 1 (SIZ1)-mediated SUMOylation as a …

Magnetic and Isotopic Analyses Unravel the Abundance and Sources of Magnetic Nanoparticles in Urban PM 2.5

Jiaxin Ye, Yaqun Yang, Xiangyang Bi, Wei Guo et autres

Abstract Magnetic nanoparticles (NPs) are increasingly recognized as an emerging threat to ecosystems and human health, yet their mass concentrations and sources in urban atmosphere remain poorly characterized. Here, we developed a robust methodology for the extraction, quantification, and source apportionment of …

Lessons from endodermal barrier-mediated glutamine leakage in shaping the root microbiome

Junyao Lu, Qianqian Yu, Peter Marhavý, Zhaojun Ding

Interactions between plant roots and soil microorganisms play an essential role in plant growth and development, influencing plant health, nutrient acquisition, and stress tolerance. These interactions occur primarily in the rhizosphere—a dynamic zone shaped by root exudates and nutrient fluxes. Although root …

Investigation of Radial Mixing Dynamics and Saturation Effect in Stirred Brown Rice Granular Systems Using Discrete Element Method

Yawen Xiao, Yajuan Wang, Qianqian Yu, Minyue Sun et autres

In rice and food processing, spray mixing plays an essential role, with radial distribution uniformity serving as a key metric for assessing mixing performance. However, noticeable variations in the radial migration behavior of brown rice particles can occur even at identical stirring-shaft …

Real-World Epidemiology, Clinical Characteristics and Outcomes of Women with Germline BRCA Mutation and Early Breast Cancer in China

Zhen Hu, Qianqian Yu, Liqin Chen, Tingting Su et autres

INTRODUCTION: The poly(ADP-ribose) polymerase inhibitor olaparib was recently approved in China for adjuvant treatment of certain patients with high-risk, human epidermal growth factor (HER2)-negative early breast cancer (eBC) and germline pathogenic/likely pathogenic mutations in BRCA1 and BRCA2 (gBRCAm). Further evidence on demographics, …

Solvent-Memory-Enabled Hierarchical Crystallization for Nested Spherulitic Architectures in Poly(vinylidene fluoride)

Yong Ma, Haijun Wang, Yao Wu, Qianqian Yu et autres

This study elucidates a nonclassical hierarchical crystallization pathway for constructing nested spherulitic architectures in poly(vinylidene fluoride) (PVDF) processed under high temperatures. Systematic investigations reveal that melting temperatures exceeding 250 °C induce the formation of γ-core/α-shell nested spherulites, whose population density increases with …
