Radiation Exposure Induced Blood–Brain Barrier Injury via Mitochondria‐Mediated Sterile Inflammation

Advanced Science, EarlyView.
This work describes a blood–brain barrier (BBB) microphysiological system (MPS) to explore the responses of BBB to radiation exposure. Following radiation exposure, obvious BBB comprise and brain endothelial injuries are detected. Mechanism study shows radiation induced significant sterile inflammation via mitochondrial dysfunction and cGAS‐STING ...

Relation of post-stroke headachto cerebrovascular pathology and hemodynamics

Folia Neuropathologica, 2022
Despite high prevalence of cerebrovascular stroke, headache attributed to ischemic strokes is often undertreated and overlooked. The aim is to detect the relation of a post-stroke headache to cerebrovascular pathology and changes in hemodynamics through ...

DNase I‐Mediated Chemotactic Nanoparticles for NETs Targeting and Microenvironment Remodeling Treatment of Acute Ischemic Stroke

Advanced Science, EarlyView.
The neutrophil extracellular traps (NETs) play an important role in reperfusion injury in ischemic stroke. Here, considering the unique vascular localization of NETs, a DNase I‐mediated NETs‐targeting nanoparticle is developed to integrate the catalytic and chemotactic functions of DNase I and achieve the synergistic regulation of the internal and ...

Impact of Intraoperative Fluid Volume on Complications After Minimally Invasive Esophagectomy: Analysis of 8782 Patients From the Japanese National Clinical Database

Annals of Gastroenterological Surgery, EarlyView.
This multicenter cohort study of 8782 esophagectomies in Japan found that higher intraoperative fluid volume significantly increased the risk of pneumonia after minimally invasive esophagectomy. Avoiding fluid overload may help reduce postoperative pneumonia.

Robotic Semi-Automated Transcranial Doppler Assessment of Cerebrovascular Autoregulation in Post-Concussion Syndrome: Methodological Considerations

Neurotrauma Reports, 2020
Post-concussion syndrome (PCS) refers to a constellation of physical, cognitive, and emotional symptoms after traumatic brain injury (TBI). Despite its incidence and impact, the underlying mechanisms of PCS are unclear.

Understanding development of jugular bulb stenosis in vein of galen malformations: identifying metrics of complex flow dynamics in the cerebral venous vasculature of infants

Frontiers in Physiology, 2023
Introduction: Computational fluid dynamics (CFD) assess biological systems based on specific boundary conditions. We propose modeling more advanced hemodynamic metrics, such as core line length (CL) and critical points which characterize complexity of ...
