"Sudden Drop" in Blood Pressure is Associated With Recanalization After Thrombolysis. [PDF]

, 2015
We aim to investigate whether the phenomenon of "sudden drop" in blood pressure (BP) within the first 2 hours is associated with vessel recanalization.We retrospectively examined clinical and imaging data from a consecutive series of patients with stroke

Iron Overload Mediates the Differential Cell Fate of Astrocytes from Neurons and Its Regulatory Mechanisms in Ischemic Stroke

Advanced Science, EarlyView.
Upon ischemia/reperfusion‐induced iron overload condition, neurons and astrocytes exhibit similar oxidative stress changes but opposite alterations in endogenous antioxidant defense mechanisms, leading to divergent ferroptotic outcomes. The iron deposition and neuronal loss are increased within the perilesional cortex of stroke patients ...

Ultrafine Molybdenum Wire Braided Neurointerventional Implants: Bridging Biodegradability and Neurovascular Safety for Stroke Treatment

Advanced Science, EarlyView.
Molybdenum (Mo), with its unique strength, uniform corrosion, and radiopacity, enables innovative biodegradable implants for transformative stroke therapy. Abstract Neurovascular implants for stroke intervention face a critical dilemma: permanent devices (e.g., nitinol stents, platinum coils) often trigger chronic inflammation and recurrence, whereas ...

Estimated pretreatment hemodynamic prognostic factors of aneurysm recurrence after endovascular embolization. [PDF]

, 2017
BACKGROUND:Hemodynamic factors play important roles in aneurysm recurrence after endovascular treatment. OBJECTIVE:Predicting the risk of recurrence by hemodynamic analysis using an untreated aneurysm model is important because such prediction is ...

NIR‐Triggered Upconversion‐Perovskite Heterostructures for Non‐Genetic, Implant‐Free Optoelectronic Neuromodulation

Advanced Science, EarlyView.
The Single‐Nanostructured Optoelectronic Vehicle for neuromodulation Activation (SNOVA) establishes a paradigm for non‐genetic, implant‐free neuromodulation. By integrating NIR‐excitable UCNPs with broadband‐absorbing perovskite QDs, SNOVA efficiently converts deeply penetrating light into localized electric fields that modulate neuronal ion dynamics ...

Iliac artery-enteric fistulas following failed pancreatic transplant

Journal of Vascular Surgery Cases and Innovative Techniques
Arterial-enteric fistulas occur from a multitude of causes, especially following surgical manipulation of vasculature. The development of an iliac artery-enteric fistula (IEF) occurs rarely in patients with failed pancreatic transplants.

Amino Acid Directed Helical Assemblies of Natural Berberine for Chirality‐Dependent Photodynamic Antibacterial Therapy

Advanced Science, EarlyView.
Helical nanostructures co‐assembled from berberine (BBR) and Fmoc‐Y display supramolecular‐chirality‐dependent photodynamic antibacterial activity. The molecular chirality of Fmoc‐Y organizes achiral BBR into chiral nanofibers, where supramolecular handedness controls bacterial surface adsorption, membrane penetration, intracellular BBR delivery, and ...
