Hyperthermia and hypermetabolism in focal cerebral ischemia.

The reliable and reproducible creation of an animal model of focal cerebral ischemia is not easily accomplished. Using a transortibal approach, we showed that occlusion of the posterior cerebral artery (PCA), middle cerebral artery (MCA), and the contralateral anterior cerebral artery (ACA) created

Mild-to-moderate neurogenic pyrexia in acute cerebral infarction.

BACKGROUND Pyrexia is often associated with unfavorable stroke outcomes. However, limited information is available on the relationship between the causes of poststroke hyperthermia and stroke prognosis, especially for mild-to-moderate neurogenic pyrexia in acute cerebral infarction. OBJECTIVE To

Acute cerebral infarction with adenomyosis in a patient with fever: a case report

Solo gli utenti registrati possono tradurre articoli

Background: It is reported that acute cerebral infarction with adenomyosis is associated with elevated D-Dimer, elevated CA125, anemia and menstruation. However, previous reports did not notice infection known as fever, which may be a potential risk factor for

Postischemic spontaneous hyperthermia is not a major aggravating factor for neuronal damage following repeated brief cerebral ischemia in the gerbil.

Brief and non-lethal cerebral ischemia produces most severe neuronal damage when such ischemia is induced repeatedly at 1-h intervals. We examined whether spontaneous postischemic hyperthermia is an aggravating factor for the cumulative damage following repeated ischemia in the gerbil. We maintained

Effect of mild hyperthermia on recovery of metabolic function after global cerebral ischemia in cats.

We investigated the effect of mild whole-body hyperthermia before and after 16 minutes of global cerebral ischemia on metabolic recovery during recirculation in cats using in vivo phosphorus-31 nuclear magnetic resonance spectroscopy. Hyperthermia (temperature 40.6 +/- 0.2 degrees C) was induced

Predictive Factors of Fever After Aneurysmal Subarachnoid Hemorrhage and Its Impact on Delayed Cerebral Ischemia and Clinical Outcomes.

OBJECTIVE Fever is relatively common and worsens neurologic injury after aneurysmal subarachnoid hemorrhage (SAH). The aim of this study was to display the time course of body temperature, identify predictive factors of fever after SAH, and evaluate its impact on delayed cerebral ischemia (DCI) and

Heat shock protein 72 overexpression protects against hyperthermia, circulatory shock, and cerebral ischemia during heatstroke.

This study extends our earlier studies in rats by applying our heatstroke model to a new species. Additionally, transgenic mice are used to examine the role of heat shock protein (HSP) 72 in experimental heatstroke. Transgenic mice that were heterozygous for a porcine HSP70i gene ([+]HSP72),

Effects of hyperthermia on infarct volume in focal embolic model of cerebral ischemia in rats.

Hyperthermia worsens outcome of stroke in patients and also in animal models. In the present study, we tested the effects of hyperthermia in a focal embolic model of cerebral ischemia in rats. Focal ischemic injury was induced by embolizing a preformed clot into the middle cerebral artery.

Effect of hyperthermia on calbindin-D 28k immunoreactivity in the hippocampal formation following transient global cerebral ischemia in gerbils.

Calbindin D-28K (CB), a Ca2+-binding protein, maintains Ca2+ homeostasis and protects neurons against various insults. Hyperthermia can exacerbate brain damage produced by ischemic insults. However, little is reported about the role of CB in the brain under hyperthermic condition during ischemic

Impact of hyperthermia before and during ischemia-reperfusion on neuronal damage and gliosis in the gerbil hippocampus induced by transient cerebral ischemia.

Hyperthermia can exacerbate the brain damage produced by ischemia. In the present study, we investigated the effects of hyperthermia before and during ischemia-reperfusion on neuronal damage and glial changes in the gerbil hippocampus following transient cerebral ischemia using cresyl violet

Hyperthermia enhances spectrin breakdown in transient focal cerebral ischemia.

Solo gli utenti registrati possono tradurre articoli

Entra registrati

Calpain-mediated spectrin degradation is triggered by cerebral ischemia and, when persistent, is thought to signal irreversible neuronal injury. Hyperthermia superimposed upon cerebral ischemia may exacerbate the injury process. In this study, we compared the extent of spectrin degradation in the

Cerebral infarction: an unusual complication of Mediterranean spotted fever.

Solo gli utenti registrati possono tradurre articoli

Entra registrati

Mediterranean spotted fever is a rickettsiosis caused by Rickettsia conorii and transmitted by the brown dog tick. It is considered as a benign disease but 5% to 10% of patients present with a malignant form which is the result of a diffuse vasculitis. We report here the first case of Mediterranean

The metabolic effects of mild hypothermia on global cerebral ischemia and recirculation in the cat: comparison to normothermia and hyperthermia.

Entra registrati

The metabolic effects of graded whole body hypothermia on complete global cerebral ischemia and recirculation was investigated in the cat. Hypothermia was induced to one of three levels prior to ischemia; T = 26.8 degrees +/- 0.5 degrees C (n = 4), T = 32.1 degrees +/- 0.2 degrees C (n = 5), and T =

The prognostic significance of subfebrility and fever in ischaemic cerebral infarction.

The prognostic influence of subfebrility and fever during the first week after an ischaemic cerebral stroke was analysed retrospectively in 110 patients with varying neurological disabilities. The results indicate that fever, and even subfebrility, carry a bad prognosis with respect to residual

Delayed postischemic hyperthermia in awake rats worsens the histopathological outcome of transient focal cerebral ischemia.

OBJECTIVE Over the past several years, it has been demonstrated that mild intraischemic or immediate postischemic hyperthermia worsens ischemic outcome in models of global and focal ischemia. Periods of hyperthermia are commonly seen in patients after stroke and cardiac arrest. The hypothesis tested
