OBJECTIVE The outcome of treatment for a spinal dural arteriovenous fistula is unpredictable. In this study, we reviewed the outcome of patients treated for this condition, in relation to pretreatment indicators. METHODS We reviewed the records of 37 consecutive patients treated either surgically or endovascularly in our department between 1989 and 2002.(More)
The aim of this study is to review the clinical outcome of patients treated for spinal dural arteriovenous malformations and investigate the presence of pretreatment indicators of outcome after short- and midterm follow-up. The authors retrospectively reviewed the records of 65 consecutive patients treated either surgically or endovascularly in 3(More)
This paper presents the vision of the Artificial Vision and Intelligent Systems Laboratory (VisLab) on future automated vehicles, ranging from sensor selection up to their extensive testing. VisLab's design choices are explained using the BRAiVE autonomous vehicle prototype as an example. BRAiVE, which is specifically designed to develop, test, and(More)
This paper presents the preliminary results of VIAC, the VisLab Intercontinental Autonomous Challenge, a test of autonomous driving along an unknown route from Italy to China. It took 3 months to run the entire test; all data have been logged, including all data generated by the sensors, vehicle data, and GPS info. This huge amount of information has been(More)
All-around view is a mandatory element for autonomous vehicles. The European V-Charge project seeks to develop an autonomous vehicle using only low-cost sensors. This paper presents a detection and tracking algorithm that covers all the area around the vehicle using 4 fisheye cameras only. The algorithm is able to detect pedestrians and vehicles and track(More)
Both children and adolescents are frequently affected by low back pain--mainly when they are involved in sporting activities--but they rarely ask for medical help, because their symptoms are often mild and self-resolving. However, in the young patients who seek orthopaedic evaluation, especially in referral centres, there is a high incidence of organic(More)
Biopsy material from human gliomas obtained during neurosurgery was used to investigate whether pathological human brain tissue is capable of producing kynurenic acid (KYNA), a natural brain metabolite which can act as an antagonist at excitatory amino acid receptors. Upon in vitro exposure to 40, 200 or 1000 microM L-kynurenine, the immediate bioprecursor(More)
