Interface Wettability Transition‐Driven Drug Release and Dual‐Phase Functionalization in Implant Abutment

open access: yesAdvanced Science, EarlyView.
A temporally controlled drug release coating is developed for abutments using a superhydrophobic coating self‐assembled on mesoporous silica. This surface provides sequential functionality: initial contamination resistance through non‐wetting, followed by controlled drug release via wettability transition.

Biomimetic Bone Marrow Monocyte Membrane‐Fused Extracellular Vesicles for Targeted Therapy of Myocardial Infarction

open access: yesAdvanced Science, EarlyView.
This study develops a biomimetic delivery system (M‐hEV) by fusing monocyte membranes with extracellular vesicles for targeted therapy of damaged cardiac tissue. The system homes to injured myocardium through specific molecular pathways. In a myocardial infarction model, M‐hEV effectively accumulates in the heart, reduces infarct size, alleviates ...

Light‐Switched Mesenchymal Stem Cells for In Situ Exosome Amplification in Craniofacial Bone Defect Reconstruction

open access: yesAdvanced Science, EarlyView.
Light‐switchable MSCs (MSC‐UCNPs) were constructed by intracellular incorporation of UCNPs. Upon 980 nm irradiation, UCNPs emitted localized ultraviolet light (365 nm), activating the ROS/HEXB/LAMP1 signaling pathway to suppress lysosome–multivesicular body fusion and thereby enhance exosome biogenesis. Embedded within an injectable hydrogel, MSC‐UCNPs

Versatile DNA‐Functionalized Biohybrid Hydrogel Platforms for Electrothermally Activated On‐Demand Payload Release

open access: yesAdvanced Science, EarlyView.
A DNA‐functionalized biohybrid hydrogel is developed by integrating Cu‐mediated nucleic acid microflowers into a thermoresponsive matrix, enabling electrothermally triggered, on‐demand payload release. The platform offers spatiotemporally controllable therapeutic delivery with promising applications in precision oncology, neural regulation, and chronic

A Bone Marrow–Mimetic Hydrogel Enables Dual‐Phase Hemostasis and Vascularized Osteogenesis for Cranial Defects

open access: yesAdvanced Science, EarlyView.
A biomimetic, fiber‐reinforced hydrogel (FE‐PDA@Fib/Gel‐TG) that enables dual‐phase cranial defect repair. The system provides: instant hemostasis in the early stage, and sustained co‐delivery of pro‐angiogenic and osteogenic signals for synergistic vascularized bone regeneration.

Tumor glomico intraóseo: Caso clínico [PDF]

open access: yes, 1999
El tumor glómico es una neoplasia que se puede encontrar por toda la superficie corporal, estando localizados la gran mayoría de ellos en las extremidades superiores, especialmente en el lecho ungueal o en los pulpejos de los dedos, siendo poco frecuente

Methylophiopogonanone a attenuates pulmonary fibrosis by inhibiting SPP1‐mediated macrophage polarization via the PI3K/Akt pathway

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Transcriptome sequencing identified secreted phosphoprotein 1 (SPP1) as a crucial target through which methylophiopogonanone A (MOA) ameliorates pulmonary fibrosis. Molecular docking and microscale thermophoresis (MST) assays confirmed a favorable binding affinity between MOA and SPP1.

A novel mouse model of endometriosis: Simulating the recurrent hemorrhagic microenvironment of clinical lesions

open access: yesAnimal Models and Experimental Medicine, EarlyView.
To address the limitations of existing models, this study innovatively established a mouse model of endometriosis (EMs) capable of mimicking cyclic bleeding. Our results confirmed that this model recapitulates the complete pathological progression from ectopic lesion establishment to systemic responses, exhibiting superior clinical relevance compared ...
