Proton magnetic resonance spectra of amino acids.
High resolution nuclear magnetic resonance spectroscopy has already proved its ability to yield valuable information on the structure, reactivity and exchange rate of a variety of compounds. Although its application to substances in aqueous solution has often been limited by solubility and exchange, it has been possible to detect the spectra of several amino acids and dipeptides in water (I). T...
متن کاملLongitudinal changes in proton magnetic resonance spectroscopy in cerebral infarction.
BACKGROUND AND PURPOSE Proton magnetic resonance spectroscopy has revealed changes in lactate and N-acetyl-aspartate in acute cerebral infarction. However, the details of these drastic changes and subsequent chronic changes have not been clarified. The purpose of this study was to disclose longitudinal changes in spectra seen in proton magnetic resonance spectroscopy. METHODS Six patients wit...
متن کاملAssessment of Cerebellar Metabolites Levels in Athletes Compared to Non-Athlete by Proton Magnetic Resonance Spectroscopy
Background: Adaptability to exercise training can increase the plasticity of the brain, and whether this can be due to a beneficial change in the neurometabolites, is uncertain. The purpose of this study was to evaluate basal metabolic concentrations of cerebellum, including N-acetyl aspartate (NAA) and Cholin(Cho) in athletes and compare them with non-athlete subjects. Materials and Methods: I...
