The cortical branches of the middle cerebral artery in the otter (Lutra lutra)

Veterinární Medicína, 2012
The cortical branches of the middle cerebral artery in the otter were described using 60 hemispheres. It was demonstrated that the artery is divided into ten permanent branches.

The Loss of Multifractality in Migraines [PDF]

arXiv, 2002
We study the middle cerebral artery blood flow velocity (MCAfv) in humans using transcranial Doppler ultrasonography (TCD). The time series of the axial flow velocity averaged over a cardiac beat interval is found to exhibit clear multifractal properties for healthy subjects. We observe a loss of multifractality for subjects with migraine.

Contrast Agent Clearance Dynamics and Diffusion in the Mouse Brain After Ventricular Administration

Advanced Science, EarlyView.
Schematic representation of contrast agent clearance by convective bulk flow from the ventricular spaces to the subarachnoid space on the ventral aspect of the brain, or by diffusion into the parenchyma across the pia‐glia or through the semi‐permeable ependyma. Abstract Fluid and solute exchange between cerebrospinal fluid (CSF) spaces and the central

Automated Segmentation for Hyperdense Middle Cerebral Artery Sign of Acute Ischemic Stroke on Non-Contrast CT Images [PDF]

arXiv, 2019
The hyperdense middle cerebral artery (MCA) dot sign has been reported as an important factor in the diagnosis of acute ischemic stroke due to large vessel occlusion. Interpreting the initial CT brain scan in these patients requires high level of expertise, and has high inter-observer variability.

Multiscale Organization of Neural Networks in a 3D Bioprinted Matrix

Advanced Science, EarlyView.
A 3D bioprint model of primary neurons has been engineered with a millimeter‐scale functional neural network, and it recapitulates in vivo transcriptomic features under both normal and disease conditions to the greatest extent. The successful integration of mature neurons and 3D bioprinting signifies a major advance in neuroscience modeling ...

Quantitative evaluation using single-photon emission computed tomography with acetazolamide is reliable for preoperative evaluation before cardiac surgery in severe carotid intracranial artery stenotic and/or occlusive disease: a case report

Journal of Cardiothoracic Surgery, 2019
Background Severe carotid and intracranial artery stenosis disease (CIAD) is major risk for perioperative stroke in coronary artery bypass grafting. Then, preoperative risk assessment is quite important.

A Novel Cranial Bone Transport Technique Repairs Skull Defect and Minimizes Brain Injury Outcome in Traumatic Brain Injury Rats

Advanced Science, EarlyView.
This study introduces a novel, safe, and effective surgical technique: Cranial bone transport (CBT) to improve traumatic brain injury (TBI) outcomes in rats. CBT significantly accelerated skull defect bone repair in addition to its promoting effects on neurological function recovery. This work provides an alternative therapy for patients suffering from

Endovascular Therapy for Isolated Cervical Internal Carotid Artery Occlusion

Stroke: Vascular and Interventional Neurology
Background Guidelines on endovascular therapy for acute ischemic stroke do not include isolated cervical internal carotid artery (cICA) occlusions. The effect of treating these lesions remains unclear.

Doppler ultrasound hemodynamic assessment in preeclampsia

Medical Journal of Babylon, 2018
Background: Preeclampsia (PE) is the main factor in maternal mortality across the world, affecting 5%–8% of pregnant women. The impairment in placental perfusion due to vascular abnormalities leads to clinical presentations and is detectable by Doppler ...

Preliminary Report: Cerebral blood flow mediates the relationship between progesterone and perceived stress symptoms among female club athletes after mild traumatic brain injury [PDF]

arXiv, 2020
Female athletes are severely understudied in the field of concussion research, despite higher prevalence for injuries and tendency to have longer recovery time. Hormonal fluctuations due to normal menstrual cycle (MC) or hormonal contraceptive (HC) use have been shown to impact both post-injury symptoms and neuroimaging measures, but have not been ...
