A Superlubricated Magnetically Steerable Microcatheter with Integrated Optical and Fluidic Channels

Advanced Robotics Research, EarlyView.
A magnetically steerable microcatheter with integrated optical and fluidic channels is developed for multifunctional navigation in tortuous anatomical environments. A surface‐grafted hydrogel coating enables low‐friction actuation. The device demonstrates stable light and fluid delivery during magnetic manipulation, offering a compact platform for ...

Occlusion of Internal Carotid Artery in Kimura's Disease

Case Reports in Medicine, 2010
We describe a unique case of Kimura's disease in which cerebral infarction was caused by occlusion of the right internal carotid artery. A 25-year-old man with Kimura's disease was admitted to our hospital because of left hemiparesis. Computed tomography

Integrin α8‐Mediated Pericyte Morphogenesis Controls Blood‐Brain Barrier Integrity

Advanced Science, EarlyView.
This study highlights that ITGA8 impacts pericyte morphology and function, both crucial for BBB integrity, via RhoA/ROCK signaling, thus influencing TGF‐β1 activation through cytoskeletal tension and ECM interactions. Notably, in post‐ischemic recovery models, ITGA8 deficiency exacerbates vascular dysfunction by impairing pericyte‐mediated BBB ...

ATF5‐Dependent GDF15 Expression Mediates Anesthesia‐Induced Neuroprotection Against Stroke

Advanced Science, EarlyView.
Anesthesia‐induced preconditioning protects against perioperative stroke. By manipulating ATF5 in excitatory neurons, it is shown that anesthesia‐driven ATF5 upregulation activates the mitochondrial unfolded protein response (UPRmt) and elevates GDF15 expression.

Endothelial BMP6 Drives Hemodynamic‐Dependent VSMCs Calcification in Carotid Atherosclerosis

Advanced Science, EarlyView.
The study demonstrates that endothelial cell (EC)‐derived BMP6 promotes the osteogenic differentiation of vascular smooth muscle cells (VSMCs) through cell‐cell interactions. Additionally, the researchers preliminarily explore the driving effect of hemodynamic factors on BMP6‐induced calcification and reveal the regulatory role of KLF4 on BMP6.
