The micronutrient iron is an essential component that plays a role in many crucial metabolic reactions. The peptide hormone hepcidin is thought to play a central role in iron homeostasis and its expression is induced by iron overloading and inflammation. Recently, hepcidin has been reported to be
The effect of alpha-tocopherol pretreatment (6 mg/100 g body wt/day, orally for a period of 90 days) on mitochondrial electron transport in myocardial infarction induced by isoproterenol (20 mg/100 g body wt, subcutaneously for two days) was studied in rats. A significant decrease was observed in
Aluminium phosphide poisoning is very common in India. It is one of the most fatal poisons. The clinical spectrum of poisoning varies depending upon the dosage and duration of consumption. The main effect of the poison is due to the release of phosphine which inhibits cytochrome oxidase and thereby
Carbon monoxide (CO) inhalation often leads to cardiac dysfunction, dysrhythmias, ischemia, infarction, and death. However, the underlying mechanism of CO toxicity is poorly understood. We hypothesize that inhaled CO interrupts myocardial oxidative phosphorylation by decreasing the activity of
Anxiety is a common comorbidity that develops after myocardial infarction and is now an established independent risk factor for cardiovascular mortality.
Here, we assessed anxiety and mapped neural activity of forebrain regions that regulate anxiety in a rat model of myocardial infarction in order
In 175 dogs myocardial infarction was produced by high ligation of descending branch of left coronary artery. At various intervals after the intervention (1, 3, 5, 10, 30, 180 days), the activities and levels of NAD, NADH, FAD, riboflavin, cytochrome C, myoglobin, some NAD-dependent Krebs cycle
The carbon monoxide poisoning still remains a main cause of fatal poisoning. The carbon monoxide poisoning occurs after inhalation of carbon monoxide. Carbon monoxide binds strongly to molecules, such as cytochrome oxidase, myoglobin, hemoglobin, causing hypoxia of tissues and organs. Carbon
Near-infrared spectroscopy (NIRS) is a cerebral monitoring method that noninvasively and continuously measures cerebral hemoglobin oxygenation and the redox state of cytochrome oxidase using highly tissue-permeable near-infrared light. This technique now has wide clinical application, and its
We measured cytochrome oxidase activity in thrombocytes from patients with senile dementia of the Alzheimer type. We found no decrease in enzyme activity in Alzheimer's disease patients when compared with patients with multi-infarct dementia, with young control donors, and with age-matched control
The effect of curantil on the values of energy metabolism in different parts of the myocardium was studied on dogs with experimental myocardial infarction. Tissue respiration, the activity of Krebs' cycle enzymes, cytochrome oxidase, pentose phosphate cycle and glycolysis, and the content of
BACKGROUND
Delayed ischemic preconditioning promotes cardioprotection via genomic reprogramming. We hypothesize that molecular regulation of mitochondrial energetics is integral to this cardioprotective program.
RESULTS
Preconditioning was induced by use of 3 episodes of 3-minute coronary artery
1. Anti-heart mitochondria autoantibodies were developed in serum from dogs following experimental myocardial infarction. 2. Heart mitochondria frozen and thawed repeatedly in a sucrose/Tris-chloride buffer retained both their functional integrity as measured by the respiratory control ratio and
Histochemical evidence of the activity and distribution of glycolysis redox enzymes, tissue respiration and terminal oxidation pattern (dehydrogenase of lactic, malic, succinic and isocitric acids, NAD-N- and NADPh-N-ase, cytochrome oxidase) as well as the levels of the major carbohydrates
