In order to study the potentials of indirect and direct detection of neuronal damages in humans by single photon emission computerized tomography (SPECT), we compared ex vivo cerebral biodistribution of [125I]PK 11195 with that of [125I]TISCH in a rat model of unilateral striatal excitotoxic lesion. Experiments on in vitro binding with [3H]PK 11195 as a(More)
The pharmacological properties of the iodinated derivative of cocaine (E)-N-(3-iodoprop-2-enyl)-2beta-carbomethoxy-3beta-(4'-me thylphenyl)nortropane (PE2I) were evaluated in vitro in the rat. Binding experiments on rat striatal membranes showed that PE2I selectively recognized the dopamine transporter (DAT) according to a single binding site model with(More)
The time course of the loss in presynaptic dopamine transporters (DAT) and of the increase in postsynaptic dopamine D2 receptors (D2R) was studied in a rat model of Parkinson's disease. For this, in vitro autoradiographic experiments were performed in the striatum using (E)-N-(3-iodoprop-2-enyl)-2beta-carbomethoxy-3beta-(4'-methy lphenyl) nortropane (PE2I),(More)
Podocalyxin (Podxl) is a type I membrane mucin-protein of the CD34 family abundantly expressed in kidney epithelial cells (podocytes) where it plays a crucial functional role. Podxl is also expressed in tissues other than kidney, like in brain, but its function is ignored. To investigate the functional role of podocalyxin (Podxl) in brain we produced the(More)
90 Venezuelan infants aged 10-20 weeks were randomly allocated to four groups which received one of the following: the M37 vaccine (1 x 10(4) pfu [plaque-forming units]); quadrivalent rotavirus vaccine (1 x 10(4) pfu each of serotype 3 rhesus rotavirus [RRV] and human rotavirus-RRV reassortants of serotypes 1, 2, and 4); balanced quadrivalent vaccine(More)
