Cav3.2 channel regulates cerebral ischemia/reperfusion injury: a promising target for intervention
Neural Regeneration ResearchCalcium influx into neurons triggers neuronal death during cerebral ischemia/reperfusion injury. Various calcium channels are involved in cerebral ischemia/reperfusion injury. Cav3.2 channel is a main subtype of T-type calcium channels.

Relationship between Hypotension and Cerebral Ischemia during Hemodialysis.
Journal of the American Society of Nephrology, 2017 The relationship between BP and downstream ischemia during hemodialysis has not been characterized. We studied the dynamic relationship between BP, real-time symptoms, and cerebral oxygenation during hemodialysis, using continuous BP and cerebral ...

Pathophysiology of Cerebral Ischemia
Neurologia medico-chirurgica, 1998 The purpose of this manuscript is to briefly review the pathophysiology of cerebral ischemia. Ischemic thresholds are well-defined in lower animals. The concept of the ischemic penumbra may include regions of brain around deeper regions of ischemia but has also been defined in terms of brain salvageable by reperfusion or by pharmacological therapies ...

Oligodendrogenesis after cerebral ischemia [PDF]
Frontiers in Cellular Neuroscience, 2013 Neural stem cells in the subventricular zone (SVZ) of the lateral ventricle of adult rodent brain generate oligodendrocyte progenitor cells (OPCs) that disperse throughout the corpus callosum and striatum where some of OPCs differentiate into mature oligodendrocytes.

Trusting Machine Learning Results from Medical Procedures in the Operating Room [PDF]
AAAI workshop on Trustworthy AI for Healthcare 2022, 2022 Machine learning can be used to analyse physiological data for several purposes. Detection of cerebral ischemia is an achievement that would have high impact on patient care. We attempted to study if collection of continous physiological data from non-invasive monitors, and analysis with machine learning could detect cerebral ischemia in tho different ...

Tonic activation of extrasynaptic NMDA receptors decreases intrinsic excitability and promotes bistability in a model of neuronal activity [PDF]
Int J Mol Sci. 2019 Dec 27;21(1). pii: E206, 2018 NMDA receptors (NMDA-R) typically contribute to excitatory synaptic transmission in the central nervous system. While calcium influx through NMDA-R plays a critical role in synaptic plasticity, experimental evidence indicates that NMDAR-mediated calcium influx also modifies neuronal excitability through the activation of calcium-activated potassium ...

Anticoagulation in cerebral ischemia. [PDF]
Stroke, 1983 Anticoagulation clearly benefits patients at risk of stroke from cerebral embolism. Conversely, patients with completed ischemic stroke are not benefited, and may show a higher mortality and morbidity because of hemorrhagic complications. Technical advances in the early, accurate diagnosis of cerebral hemorrhage, the constant infusion of heparin, and ...

RatLesNetv2: A Fully Convolutional Network for Rodent Brain Lesion Segmentation [PDF]
, 2020 We present a fully convolutional neural network (ConvNet), named RatLesNetv2, for segmenting lesions in rodent magnetic resonance (MR) brain images. RatLesNetv2 architecture resembles an autoencoder and it incorporates residual blocks that facilitate its optimization.

Cerebral Amyloid Angiopathy Is Associated With Higher R2 Relaxation Rate: An MRI and Pathology Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Cerebral amyloid angiopathy (CAA) involves β‐amyloid deposition in the walls of cortical and leptomeningeal small vessels. Transverse relaxation rate (R2) is a major source of contrast in MRI. This study tested the hypothesis that CAA is associated with R2, extracted the spatial pattern of CAA‐related R2 abnormalities, and evaluated ...
