Fatigue in multiple sclerosis and its relationship to depression and neurologic disability
We studied multiple sclerosis fatigue (MSF) and its relationship to depression and disability. Seventy-one patients [50 relapsing-remitting, 21 secondary progressive] were grouped by Fatigue SeverityExpand

Reduced prefrontal activity predicts exaggerated striatal dopaminergic function in schizophrenia
Both dopaminergic neurotransmission and prefrontal cortex (PFC) function are known to be abnormal in schizophrenia. To test the hypothesis that these phenomena are related, we measured presynapticExpand

Positron emission tomographic imaging of cardiac sympathetic innervation and function.
Sites of uptake, storage, and metabolism of [18F]fluorodopamine and excretion of [18F]fluorodopamine and its metabolites were visualized using positron emission tomographic (PET) scanning afterExpand

Fatigue in multiple sclerosis: Cross-sectional correlation with brain MRI findings in 71 patients
Article abstract Fatigue is an unexplained but common and disabling symptom in MS. We assessed fatigue in 71 patients with MS and identified MS–fatigue (MSF) and MS–nonfatigue (MSNF) groups. FatigueExpand

High‐Resolution Fluorodeoxyglucose Positron Emission Tomography Shows Both Global and Regional Cerebral Hypometabolism in Multiple Sclerosis
The authors study brain regional glucose metabolism prospectively in multiple sclerosis (MS) using high‐resolution 2‐[18‐F]fluoro‐2‐deoxy‐D‐glucose positron emission tomography (FDG PET) in 25 MSExpand

Role of iron and ferritin in MR imaging of the brain: a study in primates at different field strengths.
The authors measured in vivo signal intensity on magnetic resonance (MR) images and postmortem iron concentrations in the brains of three young and two old rhesus monkeys. T2-weighted MR imaging wasExpand

Long-term evaluation of hemiparkinsonian monkeys after adrenal autografting or cavitation alone.
Autografts of adrenal medulla were implanted into preformed cavities in the caudate nuclei of four rhesus monkeys with hemiparkinsonism induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP).Expand
