A Multidimensional Engineering Strategy Reprograms Microglia via Targeted and Sustained‐Release Extracellular Vesicles for Spinal Cord Injury Repair

Advanced Science, EarlyView.
A multifunctional EV‐based nanoplatform (Ang‐TEVs@Gel) was engineered via preconditioning, surface targeting, and ROS‐responsive hydrogel encapsulation to reprogram microglia. This system restored autophagy via miR‐664a‐3p/PIK3CA axis, cleared myelin debris, resolved neuroinflammation, and promoted axon remyelination, ultimately achieving robust motor ...

Quantification of the collagen fibre architecture of human cranial dura mater [PDF]

Journal of Anatomy, 1998
The purpose of this study was to quantify and map the gross fibre architecture of the cranial dura mater (CDM) using small angle light scattering (SALS). In SALS, HeNe laser light is passed through the tissue, and the resultant scattering pattern is analysed to determine the preferred fibre direction and degree of orientation.

Hyperostosis frontalis interna: Observed patterns, prevalence, and dementia associations in older adults

The Anatomical Record, EarlyView.
Abstract Hyperostosis frontalis interna (HFI) is a frequently underrecognized condition characterized by overgrowth of the frontal endocranium, most commonly observed in post‐menopausal women. Although its etiology remains unclear, hormonal influences and a possible relationship with neurocognitive changes have been proposed.

Overcoming intranasal delivery barriers with ultrastable polyzwitterionic siRNA nanocages for enhanced glioblastoma therapy

BMEMat, EarlyView.
A ROS‐responsive, zwitterionic nanocage enables stable, intranasal siRNA delivery to glioblastoma, promoting deep tumor penetration via non‐degradative pathways and trigeminal nerve transport. This platform achieves durable gene silencing and tumor suppression, offering a non‐invasive, storage‐stable strategy for treating glioma and other neurological ...

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

Biological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Stable intracranial imaging of dura mater-engrafted pancreatic islet cells in awake mice

Nature Communications
By transplanting pancreatic islets onto the dura mater of the mouse brain, we establish a microscopy platform that enables longitudinal intravital imaging of otherwise optically inaccessible tissue.
