Experientia, 1980
Hypertension was produced in anesthetized and conscious dogs when cerebral perfusion was reduced. It lasted up to 19 days in chronic studies, was not abolished by carotid sinus denervation nor with beta receptor blockade, but was absent after removal of brachiocephalic artery constriction (BCAC).

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.

Brain pH monitoring during ischemia
Surgical Neurology, 2000Brain tissue acidosis can result from ischemia when cerebral blood flow reduction reaches a critical value. The portable, battery-operated Khuri pH monitor has been used previously in a large number of patients undergoing cardiopulmonary bypass surgery to monitor the intramyocardial pH during aortic clamping.

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.

Revue Neurologique, 2011
The extent of the penumbra and the core of an acute ischemic stroke influence, at the given time, the impact of the recanalization of the occluded vessel on the outcome. Research studies have demonstrated that quantitative MR diffusion imaging and, to a lesser extent, CT perfusion (CTP) could provide an acceptable estimation of the size of the core ...

European Neurology, 1981
Changes in the maximal rate of some cerebral enzymatic activities related to 400ene transduction and neurotransmission (lactate dehydrogenase; citrate synthase and malate dehydrogenase; total NADH-cytochrome c reductase and cytochrome oxidase; glutamate dehydrogenase; acetylcholine esterase) were assayed both in the crude or purified mitochondrial ...

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,

Gerontology, 1987
A 15-min complete cerebral ischemia, and repetitive ischemic insults of 15-min duration each cause changes in brain cortical glucose and energy metabolism which are similar in quality but different in quantity. Abnormalities in glycolytic flux, lactate production, cessation of oxidation and energy production were found to be more pronounced with ...

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.

Diabetes, 1996
Diabetes influences brain ischemia in a number of different ways. Diabetes causes and exacerbates macroangiopathies, increases the severity of ischemia, and increases stroke mortality. Unfortunately, few studies have examined in sufficient depth the influence of diabetes on the various vascular lesions that cause brain ischemia.
