The primary goal of this study was to investigate associations between regional gray matter (GM) atrophy and neuropsychological function in multiple sclerosis (MS), while accounting for the influence of central brain atrophy (i.e. third ventricle enlargement). Using a cross-sectional design, we studied 59 MS patients with brain MRI and neuropsychological(More)
OBJECTIVE The aim of the study was to determine whether the presence of anti-Epstein-Barr virus (EBV) antibodies is associated with MRI measures of brain injury and neurodegeneration in patients with multiple sclerosis (MS). METHODS 135 patients with MS (86 women, 49 men) underwent brain MRI and testing for antibodies against EBV. MRI measurements(More)
In multiple sclerosis (MS), atrophy occurs in various cortical and subcortical regions. However, it is unclear whether this is mostly due to gray (GM) or white matter (WM) loss. Recently, a new semi-automatic brain region extraction (SABRE) technique was developed to quantify parenchyma volume in 13 hemispheric regions. This study utilized SABRE and tissue(More)
BACKGROUND Brain atrophy, as assessed by magnetic resonance imaging (MRI), has been correlated with disability in patients with multiple sclerosis (MS). Recent evidence indicates that both white matter (WM) and gray matter (GM) are subject to atrophy in patients with MS. Although neurological deficiencies in MS are primarily due to loss of WM, the clinical(More)
The most important confirmed genetic factor of susceptibility to multiple sclerosis (MS) has been identified in the HLA class II region. The hypothesis that several genes, including HLA class II, may influence the prognosis of patients with MS has been proposed. In a recent study, using low intermediate resolution typing, we found that some HLA alleles may(More)
PURPOSE To determine the role of gene-environmental interactions between the Class I and Class II HLA alleles and the humoral anti-Epstein-Barr Virus (EBV) responses in the development of brain injury and clinical disability in multiple sclerosis (MS) patients. METHODS A total of 93 MS patients (62 females; 31 males) and 122 healthy controls underwent HLA(More)
Global interconnects pose a significant challenge to the dense very deep submicron (VDSM) system-on-chips (SoC), due to increasing wire delay and its variations. Hence, interconnection techniques which decrease delay, delay variation and ensure signal integrity, play an important role in future technologies. In this regard, current-mode low-swing(More)
