PURPOSE: We aimed to validate the estimation of the brain parenchymal fraction (BPF) in patients with multiple sclerosis (MS) using synthetic magnetic resonance imaging (SyMRI) by comparison with software tools of the FMRIB Software Library (FSL). In addition to a cross-sectional method comparison, longitudinal volume changes were assessed to further elucidate the suitability of SyMRI for quantification of disease-specific changes. METHODS: MRI data from 216 patients with MS and 28 control participants were included for volume estimation by SyMRI and FSL-SIENAX...

The pathogenesis of multiple sclerosis (MS) is mediated by massive infiltration of myelin-specific T cells into the central nervous system (CNS). Self-reactive CD4+ T helper (Th) cells, specifically Th1 and Th17 cells, are hallmarks of active disease in progression, whereas Th2 cells are predominately in remission stages. Calpain has been shown to be upregulated in the CNS of MS patients and inhibition of calpain has been shown previously to decrease disease in experimental autoimmune encephalomyelitis (EAE), an animal model of MS...

Clinical and pathological findings are reported in 3 cases of cardiac tumors involving the ventricular septum and free walls. In 2 cases death occurred at ages 4 hours and 3 1/2 years and the pathological study revealed the presence of rhabdomyomas in the heart and tuberous sclerosis in the brain. The cardiac involvement was much more pronounced in the newborn infant than in the 3 1/2-year-old boy. The remaining patient, is a 6-month-old infant who is still alive. An angiocardiographic study performed at age 1 1/2-months revealed the presence of multple filling defects which were localized in the ventricular septum and in the left ventricular free wall...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
