Abstract

There is great interest in the study of dopamine (DA) pathways due to the increasing number of patients with illnesses related to the dopaminergic system and molecular imaging based in Positron Emission Tomography (PET) has been proven helpful for this task. Among the different radiopharmaceuticals available to study DA interaction, [uC]Dihydrotetrabenazine (DTBZ) has a high affinity for the vesicular monoamine transporter type 2 (VMAT2) and its binding potential (BP) is a marker of DA terminal integrity. This paper reports on the intersubject reproducibility of BP measurements in rat striatum with [11C]DTBZ using the Logan's method. [ABSTRACT FROM AUTHOR]

Abstract

In this work we applied FTIR vibrational spectroscopy in Attenuated Total Reflectance mode, to observe the transient species, in an acetone solution at very low weight concentration, due to the molecular transformation from spiropyran to merocyanine form, in four different spiropyran types. In UV/VIS spectroscopy a new peak generation in the visible region was observe. In ATR, the peak shift from 1487 cm-1 to 1510 cm-1 and two new peaks generation at 1568 cm-1 and 1595 cm-1 are associated to the ring. Also, due to the C-O break down bonding when the molecular transformation was done, the peak associated to the O-C-N bond diminished in intensity and the new peaks generations between 900 to 1000 cm-1, are associated to this molecular transformation.
