BACKGROUND A possible method of finding physiological markers of multiple sclerosis (MS) is the application of EEG quantification (QEEG) of brain activity when the subject is stressed by the demands of a cognitive task. In particular, modulations of the spectral content that take place in the EEG of patients with multiple sclerosis remitting-relapsing (RRMS) and benign multiple sclerosis (BMS) ...

BACKGROUND Investigations using classical test theory support the psychometric properties of the original version of the Multiple Sclerosis Impact Scale (MSIS-29v1), a disease-specific measure of multiple sclerosis (MS) impact (physical and psychological subscales). Later, assessments of the MSIS-29v1 in an MS community-based sample using Rasch analysis led to revisions of the instrument's resp...

OBJECTIVE To investigate the value of Expanded Disability Status Scale (EDSS) worsening sustained for at least 6 months and other parameters as predictors for disability status. DESIGN Retrospective analysis of the Multiple Sclerosis Collaborative Research Group study data. SETTING The intramuscular interferon beta-1a pivotal trial was a double-blind, placebo-controlled phase 3 study. PAR...

BACKGROUND & OBJECTIVES Published natural history data on late-onset of multiple sclerosis are limited. We aimed to assess the risk of attaining EDSS 6.0 among patients with late-onset (> 40 years) MS (LOMS) and young-onset (18-40 years) MS (YOMS). METHODS This cross-sectional cohort study was conducted to identify LOMS and YOMS patients' with relapsing remitting course at MS diagnosis. Time ...

introduction: multiple sclerosis is a chronic inflammatory disease of central nervous system. the etiology of ms is slightly known, but genetic and environmental factors are reported. vitamin d regulates gene expression and affects target cell functions. the aim of this study was to investigate the expression variation of il-2 and il-4 genes under vitamin d supplementation in patients with mult...

Remote sensors generate the huge amount of data from satellites. Nowadays, there is a large demand for real-time data for remote sensing applications, and to extract useful information from the data. This paper examines different mining approaches in various satellite image processing applications. A two level merging approach is used to extract the sea area. But, the performance is lower due t...

introduction: the mobile phone is viewed as an important communication tool and has become an integral part of the iranian society and they are increasingly using the mobile phone rather than the fixed line telephone as a way to keep in touch with their family, friends, colleagues and business associates. today, mobile phones are equipped with other features that allow further communication and...
