In a double-blind, parallel group trial, 78 subjects with social phobia received moclobemide (a new reversible inhibitor of monoamine oxidase A) phenelzine, or placebo. After eight weeks, both active drugs-phenelzine somewhat more than moclobemide--were clinically and statistically significantly more effective than placebo, as assessed by rating scales.(More)
Brain imaging techniques allow the in vivo evaluation of the human brain, leading to a better understanding of its anatomical, functional and metabolic substrate. The aim of this current report is to present a systematic and critical review of neuroimaging findings in Social Anxiety Disorder (SAD). A literature review was performed in the PubMed Medline,(More)
A flavonoid-rich diet has been associated with a lower incidence of cardiovascular diseases, probably because of the antioxidant and vasoactive properties of flavonoids. Indeed, many flavonoids show vasorelaxing properties, due to different and often not yet completely clarified mechanisms of action. Among them, the activation of vascular potassium channels(More)
This study aimed to describe the prevalence of psychiatric disorders and to identify the factors associated with Current Suicide Risk (CSR) in the first trimester of pregnancy. The Mini-International Neuropsychiatric Interview (M.I.N.I.) was employed to diagnose mental disorders in 239 women enrolled in a prospective cohort in Rio de Janeiro, Brazil. Serum(More)
It has been reported that the lifetime prevalence of panic disorder in patients with pulmonary disease is higher than epidemiologic estimates of population prevalence. We evaluated the frequency of anxiety disorders in 86 subjects from the Outpatient Asthma Clinic. Psychiatric diagnoses were assessed with the Mini-International Neuropsychiatric Interview(More)
BACKGROUND Tricyclic antidepressants and selective serotonin reuptake inhibitors (SSRIs) as well as benzodiazepines have been shown to be effective for the treatment of panic disorder. The introduction of SSRIs has enabled a greater understanding of the role of serotonin in the etiology of panic disorder; however, the role of norepinephrine has been more(More)
Presenile Dementia or Early Onset Dementia (EOD) is a public health problem, it differs from Senile Dementia, and encloses a significant number of cases; nevertheless, it is still poorly understood and underdiagnosed. This study aims to review the prevalence and etiology of EOD, comparing EOD with Senile Dementia, as well as to show the main causes of EOD(More)
Large-conductance Ca(2+)- and voltage-activated K(+) channels (Kca1.1/BK/MaxiK) are widely expressed ion channels. They provide a Ca(2+)-dependent feedback mechanism for the regulation of various body functions such as blood flow, neurotransmitter release, uresis, and immunity. In addition, a mitochondrial K(+) channel with KCa1.1-resembling properties has(More)
BACKGROUND Acute pancreatitis is among the few inflammatory diseases for which no specific pharmacological treatment is available. It has previously been shown that bile acids alter pancreatic ductal secretion and these effects are probably involved in the pathogenesis of bile-induced pancreatitis. OBJECTIVE To understand the mechanism responsible for(More)
BACKGROUND AND PURPOSE KCNQ-encoded voltage-gated potassium channels (K(v) 7) have recently been identified as important anti-constrictor elements in rodent blood vessels but the role of these channels and the effects of their modulation in human arteries remain unknown. Here, we have assessed KCNQ gene expression and function in human arteries ex vivo. (More)
