Depression in the elderly is nowadays a predominant health care problem, mainly due to the progressive aging of the population. It results from psychosocial stress, polypathology, as well as some biochemical changes which occur in the aged brain and can lead to cognitive impairments, increased symptoms from medical illness, higher utilization of health care(More)
7-Nitroindazole, a selective neuronal nitric oxide synthase inhibitor (25-200 mg kg(-1), intraperitoneally (i.p.)) antagonized audiogenic seizures in DBA/2 mice in a dose-dependent manner. We investigated the effects of 7-nitroindazole at a dose of 25 mg kg(-1) i.p., which per se did not show anticonvulsant activity against audiogenic seizures in DBA/2(More)
Penile erection is a vascular event that requires an intact endothelium to occur. A dysfunctional endothelium is an early marker for the development of atherosclerotic changes and can also contribute to the occurrence of acute cardiovascular events. The pathogenesis of both endothelial and erectile dysfunction (ED) is intimately linked through decreased(More)
Carbenoxolone, the succinyl ester of glycyrrhetinic acid, is an inhibitor of 11beta-hydroxy steroid dehydrogenase and gap junctional intercellular communication. It is currently used in clinical treatment of ulcer diseases. Systemic administration of carbenoxolone (1-40 mg/kg, intraperitoneally (i.p.)) was able to produce a dose-dependent decrease in DBA/2(More)
OBJECTIVE To report a case of visual hallucinations and psychomotor agitation probably induced by an interaction between venlafaxine and propafenone. CASE SUMMARY An 85-year-old woman was admitted for evaluation of a mood disorder on March 20, 2006. Her general practitioner had prescribed sertraline for treatment, which had started about 6 months earlier.(More)
Gabapentin (1-50 mg/kg, intraperitoneally (i.p.)) was able to antagonize audiogenic seizures in Dilute Brown Agouti DBA2J (DBA/2) mice in a dose-dependent manner. Gabapentin at dose of 2.5 mg/kg i.p., which per se did not significantly affect the occurrence of audiogenic seizures in DBA/2 mice, potentiated the anticonvulsant activity of carbamazepine,(More)
In recent years, the use of antipsychotics has been widely debated for reasons concerning their safety in elderly patients affected with dementia. To update the use of antipsychotics in elderly demented people, a MEDLINE search was conducted using the following terms: elderly, conventional and atypical antipsychotics, adverse events, dementia, and(More)
The renin-angiotensin system (RAS) exists in the brain and it may be involved in pathogenesis of neurological and psychiatric disorders including seizures. The aim of the present research was to evaluate the effects of some angiotensin-converting enzyme inhibitors (ACEi; captopril, enalapril, fosinopril and zofenopril), commonly used as antihypertensive(More)
Carbenoxolone (CBX), the succinyl ester of glycyrrhetinic acid, is an inhibitor of gap junctional intercellular communication. We have tested its possible effects upon two genetic animal models of epilepsy (WAG/Rij rats and lethargic (lh/lh) mice). Systemic administration of CBX was unable to significantly affect the occurrence of absence seizures in(More)
OBJECTIVE Individuals suffering from dementia are affected by a progressive and significant global deterioration and, consequently, might require longer assistance in the advanced stage of the illness. The illness is a great burden on the person who takes care of a patient, namely, the caregiver. This study aims to analyze the presence and relationship of(More)
