College of Environment and Ecology, Laboratory of Compound Air Pollution Identification and Control, Taiyuan University of Technology, Taiyuan, 030024, China.

The coking industry is a major source of polycyclic aromatic hydrocarbons (PAHs) and oxygenated PAHs (OPAHs). Although some OPAHs are considered to be more toxic than PAHs, limited information is available on the levels of PAH and OPAH emissions from the coking industry. Accordingly, we measured the emission factors (EF) for PAHs and OPAHs produced by the coking industry in China.

The role of different imaging modalities-non-contrast CT (NCCT), CT perfusion (CTP), and diffusion-weighted imaging (DWI)-in selecting patients with large-core stroke for endovascular thrombectomy (EVT) is a subject of ongoing debate. This study aims to determine whether patients with large-core acute ischemic stroke (AIS) undergoing EVT triaged with CTP or DWI in addition to NCCT had different clinical outcomes compared to those only triaged with NCCT. We queried the Stroke Thrombectomy and Aneurysm Registry (STAR) for patients enrolled between 2014 and 2023 who presented with anterior-circulation AIS and large ischemic core (ASPECTS < 6) who underwent EVT in 41 stroke centers in the USA, Europe, Asia, and South America.

Cancer risk increases with age, and cellular senescence may be a major contributor to cellular carcinogenesis. Enormous efforts have been made to investigate the interrelation between aging and tumors, but little is known about the comparative features of normal aging, cellular senescence, and cancer at single-cell resolution. By integrating analyses of genomics, epigenomics, and bulk and single-cell transcriptomics, we revealed a directionally opposite transcriptional profile between cellular senescence and tumorigenesis at the single-cell level, which may be affected by epigenomic regulations.

Key Laboratory of Magnetic Molecules and Magnetic Information Material of Ministry of Education, School of Chemistry and Material Science, Shanxi Normal University, Taiyuan, 030006, P.R. China.

The strategic modulation of proton transport kinetics and precise control of migration energy barriers in metal-organic frameworks (MOFs) are essential for developing next-generation proton conductors. Inspired by biological proton channels, this study introduces a dynamic regulation strategy by keto-enol tautomerism to reconcile the intrinsic trade-off between low activation energy (E) and sustained proton mobility. We successfully construct a hierarchical proton conductive system (denoted as FU@MOF-808-SOH) by integrating 5-fluorouracil (5-FU) molecules into sulfonic-functionalized MOF-808 through a two-step post-synthetic modification.

September 2025

Key Laboratory of Bioorganic Phosphorus Chemistry & Chemical Biology, Department of Chemistry, Tsinghua University, Beijing, 100084, P. R. China.

Microspheres have emerged as a pivotal platform for micron-scale drug delivery, yet their utility has been greatly hindered by limitations in biodegradability, drug loading efficiency, and release kinetics, underscoring the urgent need for a next-generation microsphere platform that integrates high performance, scalability, and multifunctionality. Leveraging host-guest recognition, a series of macrocycle-incorporated polymers is synthesized and engineered a new class of supramolecular microspheres, which feature precisely tunable components, including host molecules, guest cargoes, and polymer components, as well as customizable morphologies, while enabling cost-effective, large-scale production. Following systematic validation of the host-guest recognition between β-cyclodextrin (β-CD) and lanreotide, we developed supramolecular microspheres (LAN@S-CPMs) that achieve a drug loading capacity and release duration approximately twice that of conventional microspheres, effectively curbing the disease progression of acromegaly.
