Heat stroke was induced in intact rats in a thermal chamber (45 degrees C) and simultaneously a group of animals was subjected to overheating for the same time but was given intraperitoneal injections of ionol (120 mg/kg) for 2 days and 30 minutes before exposure in the chamber. Significant increase
Ischemic stroke is a syndrome of severe neurological responses that cause neuronal death, damage to the neurovascular unit and inflammation. Notoginsenoside R1 (NG-R1) is a neuroprotective drug that is commonly used to treat neurodegenerative and cerebrovascular diseases. However, its potential
To determine whether altered metabolic profiles represent a link between atrial dysfunction and cardioembolic (CE) stroke, and thus whether underlying dysfunctional atrial substrate may contribute to thromboembolism risk in CE stroke.METHODS
A total
Ischemic stroke, still lacking an effective neuroprotective therapy is the third leading cause of global mortality and morbidity. Here, we have applied an 8-plex iTRAQ-based 2D-LC-MS/MS strategy to study the commonly regulated infarct proteome from three different brain regions (putamen, thalamus
Morphological and histochemical investigations of the activity of succinate, malate, lactate, isocitrate, and glucoso-6-phosphate dehydrogenases, and NAD-diaphorase in the central, marginal, borderline and perifocal zones of ischemic brain infarctions were carried out. Deep changes in the activity
A number of human diseases are caused by inherited mitochondrial DNA mutations. Two of these diseases, MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes) and MERRF (myoclonic epilepsy and ragged-red fibres), are commonly caused by point mutations to tRNA genes
BACKGROUND
Ischemic brain injury due to stroke and/or cardiac arrest is a major health issue in modern society requiring urgent development of new effective therapies. The aim of this study was to evaluate mitochondrial, microcirculatory, and histological changes in a swine model of global cerebral
The present study was undertaken to determine whether naftidrofuryl oxalate, a cerebral vasodilator, may improve or attenuate microsphere embolism-induced damage to the mitochondrial tricarboxylic acid cycle. For this purpose, the intermediates in the tricarboxylic acid cycle were determined using
Because mitochondrial oxidative stress and impairment are important mediators of neuronal damage in neurodegenerative diseases and in brain ischemia/reperfusion, in the present study, we evaluated the antioxidant and mitoprotective effect of a new promising neuroprotective molecule, JM-20, in
Methods for the restoration of circulating blood volume, including the use of intravenous fluids, have been widely discussed over many years. There are no clear guidelines regarding the type of solutions, the total volume that should be transfused, or time schedules. Colloid solutions, usually
The concentrations of non-transferrin-bound iron are elevated in the brain during pathological conditions such as stroke and Alzheimer's disease. Astrocytes are specialised for sequestering this iron, however little is known about the mechanisms involved. Carboxylates, such as citrate, have been
From in vivo models of stroke it is known that ischemia/reperfusion induces oxidative stress that is accompanied by deterioration of brain mitochondria. Previously, we reported that the increase in Ca2+ induces functional breakdown and morphological disintegration in brain mitochondria subjected to
We studied a family with a myopathic form of complex I deficiency with regard to the clinical symptoms, usefulness of the exercise tolerance test with an ergometer for screening of mitochondrial abnormalities, pathological findings in biopsied muscles and genetics. In this family, none of the
A 7-year-old girl with normal psychomotor development during infancy began to have easy fatigability about 3 years of age. At the age of 5 years, she developed respiratory distress and became unconscious when the serum lactate and pyruvate levels were markedly elevated and a blood gas analysis
Diagnosis and treatment of stroke and traumatic brain injury remain significant health care challenges to society. Patient care stands to benefit from an improved understanding of the interactive biochemistry underlying neurotrauma pathobiology. In this study, we assessed the power of
