Cerebrovascular Segmentation via Vessel Oriented Filtering Network [PDF]

open access: yesarXiv, 2022
Accurate cerebrovascular segmentation from Magnetic Resonance Angiography (MRA) and Computed Tomography Angiography (CTA) is of great significance in diagnosis and treatment of cerebrovascular pathology. Due to the complexity and topology variability of blood vessels, complete and accurate segmentation of vascular network is still a challenge.

Microwave Tomographic Imaging of Cerebrovascular Accidents by Using High-Performance Computing [PDF]

open access: yesParallel Computing, 85:88-97, 2019, 2016
The motivation of this work is the detection of cerebrovascular accidents by microwave tomographic imaging. This requires the solution of an inverse problem relying on a minimization algorithm (for example, gradient-based), where successive iterations consist in repeated solutions of a direct problem.

Simulation‐based team‐training in acute stroke: Is it safe to speed up?

open access: yesBrain and Behavior, Volume 12, Issue 12, December 2022., 2022
Abstract Background In acute ischemic stroke (AIS), rapid treatment with intravenous thrombolysis (IVT) is crucial for good clinical outcome. Weekly simulation‐based team‐training of the stroke treatment team was implemented, resulting in faster treatment times.

Clinical outcomes and cognitive impairments between progressive supranuclear palsy and multiple system atrophy

open access: yesBrain and Behavior, Volume 12, Issue 12, December 2022., 2022
Abstract Background Both progressive supranuclear palsy (PSP) and multiple system atrophy (MSA) belong to atypical parkinsonian syndromes. It is important to differentiate these diseases accurately. We compared clinical outcomes and cognitive impairments between PSP and MSA. Methods Eighty‐five MSA parkinsonism type (MSA‐P) patients and 76 PSP patients

Time-dependent changes of autophagy and apoptosis in lipopolysaccharide-induced rat acute lung injury [PDF]

open access: yesIranian Journal of Basic Medical Sciences, 2016
Objective(s): Abnormal lung cell death including autophagy and apoptosis is the central feature in acute lung injury (ALI). To identify the cellular mechanisms and the chronology by which different types of lung cell death are activated during ...

Effect of Low Diastolic Blood Pressure to Cardiovascular Risk in Patients With Ischemic Stroke or Transient Ischemic Attacks Under Different Systolic Blood Pressure Levels

open access: yesFrontiers in Neurology, 2020
Background: In the context of recently updated strategies of pressure management, there is a paucity of evidence on the effect of diastolic blood pressure (DBP) level on adverse events among stroke patients.
