An umbilical point on a non-real-analytic surface

open access: yesHiroshima Mathematical Journal, 2003
The index of an isolated umbilical point on a surface in three-dimensional Euclidean space is studied. The main attention is paid to the following index conjecture: the index of an isolated umbilical point is not more than one. This conjecture is motivated by studying constant mean curvature surfaces whose isolated umbilical points are always of ...

ROS‐Responsive Nanoparticle Delivery of Dexmedetomidine Protects the Gut Vascular Barrier After Intestinal Ischemia/Reperfusion via the HDAC‐H3K27ac‐TCF4 Axis

open access: yesAdvanced Science, EarlyView.
A low dose of dexmedetomidine, delivered by ROS‐responsive nanoparticles, preferentially accumulates in the ischemic intestine and restores gut vascular barrier integrity after ischemia/reperfusion injury. This nanoparticle‐based strategy prevents bacterial translocation and liver damage without cardiorespiratory side effects, working through HDAC ...

Macrophage Dab1 Links Early Hypoxia to Adaptive Angiogenesis to Drive Peripheral Nerve Repair

open access: yesAdvanced Science, EarlyView.
Schematic diagram illustrating the Dab1‐linked hypoxia signaling pathway that accelerates angiogenesis and consequent nerve regeneration. Following PNI, a hypoxic microenvironment develops. Hypoxia induces macrophage Dab1 phosphorylation, resulting in NHE‐1 upregulation, HIF‐1α stabilization, and VEGF‐A expression. This cascade promotes angiogenesis in

Microglial TSPAN4‐Dependent Migrasomes Promote Pathological Retinal Neovascularization via Immune‐Vascular Crosstalk

open access: yesAdvanced Science, EarlyView.
Combined high‐glucose and hypoxic stress switches microglia into a TSPAN4‐dependent migrasome‐producing state. These migrasomes deliver pro‐angiogenic signals to endothelial cells, activating HIF‐1α/VEGF signaling, disrupting vascular junctions, and fueling pathological neovascularization. This work uncovers migrasome‐mediated immune‐vascular crosstalk

Magnetically Guided Macrophage Immunobots Coordinate Iron‐Metabolic Cascades and Immunogenic Ferroptosis for Tumor Immunotherapy

open access: yesAdvanced Science, EarlyView.
Magnetically guided macrophage immunobots integrate active tumor targeting with immunometabolic therapy. After systemic administration, magnetic actuation enhances immunobot retention and tumor penetration, while LPS‐functionalized FePt microrollers sustain M1‐like polarization through inflammatory and iron‐amplified oxidative signaling and trigger ...

CMC-surfaces, flat structures and umbilical points

open access: yes, 2001
A short proof of the Caratheodory conjecture about index of an isolated umbilic on the convex 2-dimensional sphere is suggested. The argument is based on the study of geodesic lines near cone-type singularity of a metric induced by holomorphic quadratic differentials.

Neuron‐Derived Vesicular circMagi1 Restrains Vascular Repair After Ischemic Stroke by Promoting TRIM65‐Mediated ANXA2 Degradation

open access: yesAdvanced Science, EarlyView.
After ischemic stroke, injured neurons transfer circMagi1 to endothelial cells through extracellular vesicles. Within endothelial cells, circMagi1 binds ANXA2 and enhances its engagement with TRIM65, promoting ANXA2 ubiquitination and proteasomal degradation to constrain angiogenic repair.

Developing Highly Effective Nanoparticle mRNA Therapeutic for Pediatric Acute Respiratory Distress Syndrome

open access: yesAdvanced Science, EarlyView.
Sepsis‑induced pediatric acute respiratory distress syndrome suppresses FOXF1 in lung endothelial cells which causes life‐threatening lung damage. To counter this, researchers developed nanoparticles that specifically target these cells and deliver FOXF1 mRNA.

Printing‐Assisted Integration of Thermal, Fluidic and Electrical Components in Implants for Focal Brain Cooling

open access: yesAdvanced Science, EarlyView.
Extrusion‐based 3D printing of silicones and discrete electronic components are combined to create cortical implants for rodents that integrate thermal neuromodulation and electrical recording. Linked to an autonomous auxiliary driver unit, the system enables rapid, stable and localized hypothermia alongside ECoG recording.
