The Effects of Middle Cerebral Artery Occlusion on Central Nervous System Apoptotic Events in Normal and Diabetic Rats [PDF]

, 2003
Apoptosis and neural degeneration are characteristics of cerebral ischemia and brain damage. Diabetes is associated with worsening of brain damage following ischemic events. In this study, the authors characterize the influence of focal cerebral ischemia,

Spatial Transcriptomic Analysis Reveals HDAC Inhibition Modulates Microglial Dynamics to Protect Against Ischemic Stroke in Mice

Glia, EarlyView.
Spatial transcriptomic analysis unravels the mechanisms by which HDACi ameliorates neuroinflammation and enhances neuroprotection by modulating the expression of microglial transcriptomes in the ischemic mouse brain. ABSTRACT Ischemic stroke significantly contributes to global morbidity and disability through a cascade of neurological responses ...

A Method for Imaging the Ischemic Penumbra with MRI using IVIM [PDF]

This work examines the hypothesis that intravoxel incoherent motion MRI (IVIM) can quantify local cerebral blood flow (qCBF), infarct volume, and define the ischemic penumbra for determination of the perfusion-diffusion mismatch (PWI/DWI) volume in a setting of acute ischemic stroke.

Research progress of neurovascular units involved in ischemic stroke

Ibrain, EarlyView.
The brain receives less blood when an ischemic stroke develops, which damages neurons and leads to an increased release of Pro‐inflammatory mediators that activate neurovascular unit (NVU). When the tight junctions are broken and the basement membrane is disrupted by matrix metalloproteinases produced by active endothelial and pericellular cells ...

Fractal Rigidity in Migraine [PDF]

, 2003
We study the middle cerebral artery blood flow velocity (MCAfv) in humans using transcranial Doppler ultrasonography (TCD). Scaling properties of time series of the axial flow velocity averaged over a cardiac beat interval may be characterized by two exponents. The short time scaling exponent (STSE) determines the statistical properties of fluctuations

Cordycepin mediates neuroprotection against apoptosis via ERK/CREB signaling activation in Aβ1–42‐induced neuronal cell models

Ibrain, Volume 11, Issue 1, Page 84-97, Spring 2025.
This study demonstrates cordycepin's neuroprotective effects against Aβ1–42‐induced apoptosis in neuronal cells, mediated through the activation of the extracellular signal‐regulated kinase/cyclic AMP‐responsive element‐binding protein (ERK/CREB) signaling pathway.

Associations of Central Arterial Stiffness With Brain White Matter Integrity and Gray Matter Volume in MRI Across the Adult Lifespan

Journal of Magnetic Resonance Imaging, EarlyView.
Background Central arterial stiffening is associated with brain white matter (WM) damage and gray matter (GM) volume loss in older adults, but little is known about this association from an adult lifespan perspective. Purpose To investigate the associations of central arterial stiffness with WM microstructural organization, WM lesion load, cortical ...

The Diagnostic Value of Contrast‐Enhanced Vessel Wall MRI for Diagnosing Neuropsychiatric Systemic Lupus Erythematosus

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Imaging biomarkers for neuropsychiatric systemic lupus erythematosus (NPSLE) are highly needed, and intracranial contrast‐enhanced vessel wall imaging (CE‐VWI) can potentially detect cerebral vessel wall abnormalities in lupus. Purpose To evaluate the diagnostic value of CE‐VWI in differentiating NPSLE from non‐NPSLE.

Increased blood pressure variability upon standing up improves reproducibility of cerebral autoregulation indices [PDF]

arXiv, 2017
Dynamic cerebral autoregulation, that is the transient response of cerebral blood flow to changes in arterial blood pressure, is currently assessed using a variety of different time series methods and data collection protocols. In the continuing absence of a gold standard for the study of cerebral autoregulation it is unclear to what extent does the ...
