3D Brain Vascular Niche Model Captures Glioblastoma Infiltration, Dormancy, and Gene Signatures

open access: yesAdvanced Science, EarlyView.
This study developed a 3D brain vascular niche model that capture the key features of glioblastoma including perivascular infiltration, gene signature, dormancy and chemo resistance, by comparing 3D model with in vivo condition using identical glioma stem cells.

Cerebral Arterial Inflow and Venous Outflow Assessment Using 4D Flow MRI in Adult and Pediatric Patients

open access: yesJournal of Vascular Diseases
Background and Purpose: The cerebral circulation is highly regulated to maintain brain perfusion, keeping an equilibrium between the brain tissue, cerebrospinal fluid (CSF) and blood of the arterial and venous systems.

Angioarchitectural evolution of clival dural arteriovenous fistulas in two patients. [PDF]

open access: yes, 2015
Dural arteriovenous fistulas (dAVFs) may present in a variety of ways, including as carotid-cavernous sinus fistulas. The ophthalmologic sequelae of carotid-cavernous sinus fistulas are known and recognizable, but less commonly seen is the rare clival ...

Parvalbumin Interneuron‐Dependent Hippocampal Neurogenesis Evoked by Prolonged Rhythmic Light Flicker

open access: yesAdvanced Science, EarlyView.
This study demonstrates that prolonged rhythmic 40 Hz light flicker enhances spatial learning by stimulating PV interneuron‐dependent neurogenesis. The light flicker selectively activates PV interneurons, which enhances GABAergic support for the integration of immature neurons in the adult dentate gyrus.

Idiopathic Bilateral Internal Jugular Vein Thrombosis Diagnosed by Point-of-Care Ultrasound [PDF]

open access: yes, 2020
Internal jugular vein (IJV) thrombosis is an unusual condition, especially when it develops bilaterally. This is a case of bilateral IJV thrombosis in a 77-year old female who presented to the emergency department with neck and arm swelling after ...

Bidirectional Interaction Between the Brain and Bone in Traumatic Brain Injury

open access: yesAdvanced Science, EarlyView.
Traumatic brain injury (TBI) disrupts the blood–brain barrier and activates neuroimmune responses, causing metabolic disturbances and long‐term bone mass loss. Concurrent fractures accelerate healing and enhance osteogenesis but disrupt regulatory mechanisms, leading to altered bone dynamics and exacerbating neuroinflammation, complicating recovery ...

Why should we report posterior fossa emissary veins?

open access: yesDiagnostic and Interventional Radiology, 2014
Posterior fossa emissary veins are valveless veins that pass through cranial apertures. They participate in extracranial venous drainage of the posterior fossa dural sinuses.

Neutrophil Mobilization Triggers Microglial Functional Change to Exacerbate Cerebral Ischemia‐Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
These study underscores the pivotal role of neutrophil‐derived myeloid‐related protein 14 (MRP14) in the pathophysiology of acute ischemic stroke (AIS). MRP14 not only disrupts mitochondrial function, thereby inhibiting microglial phagocytosis of neutrophils, but also activates microglial pyroptosis, exacerbating neuroinflammation following AIS ...

An Experimental Investigation of White Matter Venous Hemodynamics: Basic Physiology and Disruption in Neuroinflammatory Disease

open access: yesFrontiers in Neurology, 2020
The white matter is highly vascularised by the cerebral venous system. In this paper, we describe a unique blood oxygen-level dependent (BOLD) signal within the white matter using functional MRI and spatial independent components analysis.
