Global Brain Ischemia and Reperfusion
Annals of Emergency Medicine, 1996Brain damage accompanying cardiac arrest and resuscitation is frequent and devastating. Neurons in the hippocampus CA1 and CA4 zones and cortical layers III and V are selectively vulnerable to death after injury by ischemia and reperfusion. Ultrastructural evidence indicates that most of the structural damage is associated with reperfusion, during ...

Vascular Protection in Brain Ischemia
Cerebrovascular Diseases, 2006Vascular damage occurring after cerebral ischemia may lead to a worse outcome in patients with ischemic stroke, as it facilitates edema formation and hemorrhagic transformation. There are several phases in the development of vascular injury (acute, subacute and chronic) and different mediators act in each one.

Neurogenesis following brain ischemia
Developmental Brain Research, 2002Following 5 or 10 min of global ischemia in the adult gerbil there is a tenfold increase in the birth of new cells in the subgranular zone of dentate gyrus of the hippocampus as assessed using BrdU incorporation. This begins at 7 days, peaks at 11 days, and decreases thereafter. Over the next month approximately 25% of the newborn cells disappear.

Inflammation of the Brain after Ischemia
1996Cytokines which promote emigration of leukocytes from the vascular lumen into the injured brain tissue are produced at the site of incipient cerebral infarction. The blood-borne invaders then accelerate the decomposition of brain cells by their toxic by-products, phagocytic action, and by the immune reaction.

Thromboinflammation in Brain Ischemia
Stroke, 2022Despite decades of promising preclinical validation and clinical translation, ischemic stroke still remains as one of the leading causes of death and disability worldwide. Within its complex pathophysiological signatures, thrombosis and inflammation, that is, thromboinflammation, are highly interconnected processes leading to cerebral vessel occlusion,

Purinergic signalling in brain ischemia
Neuropharmacology, 2016Ischemia is a multifactorial pathology characterized by different events evolving in the time. After ischemia a primary damage due to the early massive increase of extracellular glutamate is followed by activation of resident immune cells, i.e microglia, and production or activation of inflammation mediators.

Topics in magnetic resonance imaging : TMRI, 1990
The sensitivity of MRI to changes in water state and volume makes it the most desirable modality for imaging early brain ischemia. Its sensitivity is reflected in the ability to show ischemic changes in the white matter of the asymptomatic elderly, which are attributed to axonal loss, demyelination, and gliosis.

Cerebral ischemia and brain histamine
Brain Research Reviews, 2005Cerebral ischemia induces excess release of glutamate and an increase in the intracellular Ca(2+) concentration in neurons, which provokes enzymatic process leading to irreversible neuronal injury. Histamine plays a role as a neurotransmitter in the mammalian brain, and histamine release from nerve endings is enhanced in ischemia by facilitation of ...

Hyperthermia and Brain Ischemia
1997This chapter reviews recent experimental studies concerning the detrimental consequences of hyperthermia on ischemic outcome. The chapter also discusses potential mechanisms underlying the detrimential consequences of mild hyperthermia. Fever is frequently observed following cardiopulmonary resuscitation and is considered prognostic of poor outcome in ...

Cerebrovascular and brain metabolism reviews, 1993
Recent experimental data indicate a probable role of adenosine as an endogenous neuroprotective substance in brain ischemia. This nucleoside is rapidly formed during ischemia as a result of intracellular breakdown of ATP and it is subsequently transported into the extracellular space.
