BACKGROUND AND PURPOSE Patients with MR imaging-negative epilepsy could have subtle FCD. Our aim was to determine if structural changes could be identified by using DTI in children with intractable epilepsy, from MR imaging-visible FCD and MR imaging-negative localization-related epilepsy, that were concordant with the epileptogenic zone as defined by using the MEG dipole cluster. MATERIALS A...

The actual knowledge of traffic performances and travel patterns existing in an urban area is crucial to quantify the effects of transportation improvements and of actions that have to be pursued to improve mobility, as well as even an essential input to calibrate land use and traffic simulation models. In this view the use of Floating-Car Data (FCD) is emerging as a reliable and cost-effective...

PURPOSE. To devise a mathematical disease classification model for eyes with primary guttata cornea, on the bases of endothelial loss trajectory and probability of advanced disease. METHODS. A series of 1971 patients (3281 eyes), some with and some without guttata corneas, undergoing specular microscopy were retrospectively reviewed. The eyes were classified into four stages; stage 0, without g...

BACKGROUND Focal cortical dysplasia (FCD) is the most common cause of intractable epilepsy in children and adolescent. PURPOSE To evaluate the application value of magnetic source imaging (MSI) in treatment of magnetic resonance imaging (MRI)-negative FCD patients with epilepsy. METHODS MSI characteristics of 17 cases of MRI-negative focal cortical dysplasia patients with epilepsy were retr...

BACKGROUND Depression and loneliness are prevalent and highly correlated phenomena among the elderly and influence both physical and mental health. Brain functional connectivity changes associated with depressive symptoms and loneliness are not fully understood. METHODS A cross-sectional functional MRI study was conducted among 85 non-demented male elders. Geriatric depression scale-short for...

We show that it is possible to increase the performance of the coupled-dipole approximation (CDA) for scattering by using concepts from the sampling theory. In standard CDA, the source in each discretized cell is represented by a point dipole and the corresponding scattered field given by Green’s tensor. In the present approach, the source has a certain spatial extension, and the corresponding ...

UNLABELLED Focal cortical dysplasia (FCD) and mixed neuronal and glial tumors share many clinical characteristics; therefore, the presurgical differential diagnosis of these diseases using MRI is difficult in some cases. The aim of this study was to determine whether (11)C-methionine PET, compared with (18)F-FDG PET, was useful for the evaluation of these diseases. METHODS The clinical and im...

Tooth loss is highly prevalent in Brazil, especially among the elderly, where more than three million need bimaxillary dentures. The federal government instituted Specialized Dental Care Centers (SDCC) to remedy this situation. The scope of this study was to evaluate one attribute of these Centers, namely the provision of full conventional dentures (FCD) from the perspective of quality and sati...

Schizophrenia is a disorder of brain dysconnectivity, and both the connection strength and connection number are disrupted in patients with schizophrenia. The functional connectivity density (FCD) can reflect alterations in the connection number. Alterations in the global FCD (gFCD) in schizophrenia were previously demonstrated; however, alterations in two other indices of the pathological char...
