The RNA interference (RNAi) technique is a recent technology that uses double-stranded RNA molecules to promote potent and specific gene silencing. The application of this technique to molecular biology has increased considerably, from gene function identification to disease treatment. However, not all small interfering RNAs (siRNAs) are equally efficient,(More)
We describe a computational method to assist radiologists in performing better, more reliable and simpler diagnosis of neurocysticercosis (NC). Based on this method we implemented a software system that counts and measures the calcifications related to NC in computed tomography (CT) scans, thus reducing errors regarding visual inspection and providing(More)
It is reported a case of a 61 years-old man with progressive asthenia, disfagia, disphonia and diplopia, of variable intensity during the day, who had a very good response to anticolinesterasic drugs and corticosteroids. The repetitive stimulation tests at low frequency, resulted in large increment (maximum 275%) of the basal voltage after exercise. At high(More)
A 33-year-old female with neurofibromatosis and intracranial vascular lesions of the Moya-Moya type is reported. Clinical and angiographic aspects of both syndromes are discussed with respect to earlier reports of this rare association, with the conclusion that it produces slow intellectual and motor deterioration in adolescents or young adults. There are(More)
