Potassium channel activators protect the N-methyl-D-aspartate-induced cerebral vascular dilation after combined hypoxia and ischemia in piglets [PDF]

open access: yes, 1998
Background and Purpose-Cerebral arteriolar dilation to N-methyl-D-aspartate (NMDA) is a neuronally mediated multistep process that is sensitive to cerebral hypoxia and ischemia (H/I).

Early changes in transient adenosine during cerebral ischemia and reperfusion injury. [PDF]

open access: yesPLoS ONE, 2018
Adenosine is an important neuromodulator in the central nervous system, and tissue adenosine levels increase during ischemic events, attenuating excitotoxic neuronal injury.

microRNA-455-5p alleviates neuroinflammation in cerebral ischemia/reperfusion injury

open access: yesNeural Regeneration Research, 2022
Neuroinflammation is a major pathophysiological factor that results in the development of brain injury after cerebral ischemia/reperfusion. Downregulation of microRNA (miR)-455-5p after ischemic stroke has been considered a potential biomarker and ...

Neuroprotective effects of ischemic preconditioning on hippocampal CA1 pyramidal neurons through maintaining calbindin D28k immunoreactivity following subsequent transient cerebral ischemia

open access: yesNeural Regeneration Research, 2017
Ischemic preconditioning elicited by a non-fatal brief occlusion of blood flow has been applied for an experimental therapeutic strategy against a subsequent fatal ischemic insult.

Pathophysiology of Cerebral Ischemia

open access: yesNeurologia 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 ...

A depletable pool of adenosine in area CA1 of the rat hippocampus [PDF]

open access: yes, 2001
Adenosine plays a major modulatory and neuroprotective role in the mammalian CNS. During cerebral metabolic stress, such as hypoxia or ischemia, the increase in extracellular adenosine inhibits excitatory synaptic transmission onto vulnerable neurons via

Epigenetic Mechanisms in Cerebral Ischemia [PDF]

open access: yesJournal of Cerebral Blood Flow & Metabolism, 2013
Treatment efficacy for ischemic stroke represents a major challenge. Despite fundamental advances in the understanding of stroke etiology, therapeutic options to improve functional recovery remain limited. However, growing knowledge in the field of epigenetics has dramatically changed our understanding of gene regulation in the last few decades ...

[18F]DPA-714: Direct Comparison with [11C]PK11195 in a Model of Cerebral Ischemia in Rats [PDF]

open access: yes, 2013
Purpose: Neuroinflammation is involved in several brain disorders and can be monitored through expression of the translocator protein 18 kDa (TSPO) on activated microglia.

Cav3.2 channel regulates cerebral ischemia/reperfusion injury: a promising target for intervention

open access: yesNeural Regeneration Research
Calcium 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.

MicroRNA-670 aggravates cerebral ischemia/reperfusion injury via the Yap pathway

open access: yesNeural Regeneration Research, 2021
Apoptosis is an important programmed cell death process involved in ischemia/reperfusion injury. MicroRNAs are considered to play an important role in the molecular mechanism underlying the regulation of cerebral ischemia and reperfusion injury. However,
