1. O uso de células-tronco adultas em modelos experimentais de crises convulsivas. / The use of adult stem cells in experimental models of seizures.
In Brazil, it is estimated that epilepsy affects from 2% of the population, about three million people at different ages and social classes. The use of antiepileptic drugs is the most common form of seizure control, although about 50- 70% of patients with epilepsy are refractory to medication. Because of difficulties in finding effective treatments, it is cr

2. Assessment of the cardiovascular effects of electroconvulsive therapy in individuals older than 50 years
To evaluate the impact of electroconvulsive therapy on arterial blood pressure, heart rate, heart rate variability, and the occurrence of ischemia or arrhythmias, 38 (18 men) depressive patients free from systemic diseases, 50 to 83 years old (mean: 64.7 ± 8.6) underwent electroconvulsive therapy. All patients were studied with simultaneous 24-h ambulatory

3. Electrocardiographic and Blood Pressure Alterations During Electroconvulsive Therapy in Young Adults
OBJECTIVE - To study cardiovascular alterations in young patients with no apparent organic disease who underwent electroconvulsive therapy. METHODS - The study comprised 47 healthy patients (22 males and 25 females) with a mean age of 30.3 years, who underwent electroconvulsive therapy. Ambulatory blood pressure monitoring and continuous electrocardiographic

4. Compound 48/80, a histamine-depleting agent, blocks the protective effect of morphine against electroconvulsive shock in mice
We have shown that morphine has an anticonvulsive effect against maximal electroconvulsive shock (MES) in mice, and this effect is antagonized by histamine H1-receptor antagonists. Brain histamine is localized both in neurons and in mast cells, and morphine is known to enhance the turnover of neuronal histamine and to release histamine from mast cells. In th

5. INCREASE IN RAT BRAIN TYROSINE HYDROXYLASE ACTIVITY PRODUCED BY ELECTROCONVULSIVE SHOCK*
A sustained increase in the turnover of norepinephrine coupled with an increased concentration of that amine has, in a previous study, been observed in the brains of rats exposed to electroconvulsive shock twice daily for one week. The phenomenon has been further examined by studying the effects of a similar regimen of electroconvulsive shock upon tyrosine h

7. Electroconvulsive shock increases preproenkephalin messenger RNA abundance in rat hypothalamus.
Daily administration of electroconvulsive shock (ECS) to rats for 10 days increased the content of [Met5]enkephalin in the hypothalamus and the striatum by 64% and 45%, respectively. The effect of ECS on the relative abundance of mRNA coding for the enkephalin precursor preproenkephalin was investigated. Analysis by cell-free translation of polyadenylylated

8. Repeated electroconvulsive shock produces long-lasting increases in messenger RNA expression of corticotropin-releasing hormone and tyrosine hydroxylase in rat brain. Therapeutic implications.
Electroconvulsive shock (ECS) is a highly effective therapy for the treatment of major depression, but its mechanisms of action are not known. We report that repeated ECS in rats produces enduring changes in two clinically relevant stress-responsive brain systems: (a) the hypothalamic-pituitary-adrenal axis regulated by corticotropin-releasing hormone (CRH)

9. Electroconvulsive shock and lidocaine reveal rapid consolidation of spatial working memory in the water maze.
Head trauma leading to concussion and electroconvulsive shock (ECS) in humans causes amnesia for events that occurred shortly before the injury (retrograde amnesia). The present experiment investigated the amnesic effect of lidocaine and ECS in 25 rats trained on a working memory version of the Morris water task. Each day, the escape platform was moved to a

10. A role for galanin in antidepressant actions with a focus on the dorsal raphe nucleus
Selective serotonin reuptake inhibitors, such as fluoxetine (FLX), are the most commonly used drugs in the treatment of major depression. However, there is a limited understanding of their molecular mechanism of action. Although the acute effect of selective serotonin reuptake inhibitors in elevating synaptic serotonin concentrations is well known, the clini
