A Proton Magnetic Resonance Study of Dialkyl Terephthalate Dianions

Asperger syndrome: a proton magnetic resonance spectroscopy study of brain.

BACKGROUND Asperger syndrome (AS; an autistic disorder) is associated with impaired social skills and obsessional/repetitive behavior. Patients with autism have significant abnormalities in the frontal lobe and frontoparietal connectivity. Nobody has examined the relationship between abnormalities in the frontal and parietal lobes and clinical symptoms in people with AS. METHODS We used in vi...

Dementia in Parkinson disease: a proton magnetic resonance spectroscopy study.

BACKGROUND Magnetic resonance spectroscopy has been shown to be useful in differentiating idiopathic Parkinson disease (PD) from atypical parkinsonian syndromes such as progressive supranuclear palsy, multiple system atrophy, and corticobasal degeneration. OBJECTIVE To systematically investigate the utility of proton magnetic resonance spectroscopy in distinguishing between idiopathic PD with...

Proton Nuclear Magnetic Resonance Study of Water in Flocs

Polymer/surfactant adsorption can lead to colloidal stability or particle flocculation, both of which are of importance in many industrial processes. Floc structure is one of the most important features of particle flocculation and this involves flOC-size, density and strength.1~ Spectroscopic techniques to investigate floc structure have been mainly limited to small-angle neutron scattering (S...

Proton magnetic resonance study of ferredoxin from Clostridium pasteurianum.

Magnetic susceptibilities of both reduced and oxidized ferredoxin from Clostridium pasteurianum were obtained in solution. Whereas the reduced form exhibits a Curie law behavior, the magnetic susceptibility of oxidized ferredoxin in fact increases with temperature and suggests extensive antiferromagnetic exchange coupling between the component iron atoms. Contact-shifted resonances are observed...
