Synthesis of a nonpeptide carbon-11 labeled substance P antagonist for PET studies
(Elsevier, 1993-05)
CP 96,345 is a nonpeptide high affinity antagonist of the substance P (NK1) receptor. The radiosynthesis of [11C]CP 96,345 suitable for Positron Emission Tomography (PET) applications is described. [11C]CP 96,345 was ...
FDG PET imaging of paragangliomas of the neck: comparison with MIBG SPET
(Springer-Verlag, 1995-11)
Two patients with cervical paragangliomas underwent positron emission tomography (PET) with 2-[ 18 F]-fluoro-2-deoxy-D-glucose (FDG). There was marked tumor uptake and retention of FDG. Adjacent salivary gland accumulation ...
Synthesis of the 123I- and 125I-labeled cholinergic nerve marker (-)-5-iodobenzovesamicol
(Elsevier, 1993-11)
The highly toxic curaremimetic and cholinergic neuron marker (-)-5-iodobenzovesamicol (IBVM) has been labeled with iodine-125 and iodine-123. [125I]IBVM, suitable for animal distribution and ex vivo autoradiographic studies, ...
Selective resonance enhanced multiphoton ionization of aromatic polymers in supersonic beam mass spectrometry
(Elsevier, 1991-07-15)
Various polymers have been studied using a pulsed laser evaporation method for volatilizing these species and entraining them into a supersonic jet expansion followed by resonance enhanced multiphoton ionization (REMPI) ...
Successful and unsuccessful approaches to imaging carcinoids: Comparison of a radiolabelled tryptophan hydroxylase inhibitor with a tracer of biogenic amine uptake and storage, and a somatostatin analogue
(Springer-Verlag, 1996-02)
A mouse mastocytoma model was used to determine the biodistribution and tumour uptake of four radiopharmaceuticals developed to target the serotonin synthetic pathway in carcinoid tumours. Three of the compounds were ...
Polarized Raman spectra of oriented films of Α-helical poly( L -alanine) and its N -deuterated analogue
(John Wiley & Sons, Ltd., 1998-01)
Polarized Raman spectra were obtained on well oriented films of Α-helical poly( L -alanine) (Α-PLA) and its N -deuterated analogue in order to obtain definitive assignments of the E 2 -species modes. Such assignments ...
Rotational energy dispersions: Analytic descriptions
(Elsevier, 1992-09)
Closed-form analytic expressions parametric in the centrifugal displacement are presented for the dependence of the classical rotational energy of a harmonic oscillator (HO), Morse oscillator (MO), and Lennard-Jones 6-12 ...
Phaeochromocytoma and functioning paraganglioma in childhood and adolescence: role of iodine 131 metaiodobenzylguanidine
(Springer-Verlag, 1991-03)
Phaeochromocytomas and functioning paragangliomas are rare tumours in childhood and adolescence. We review our experience of 43 cases (24 men, 19 women) who were first diagnosed at the age of ⩽ 18 years. All patients were ...
Electric Dipole Moments of Rare Gas-Carbonyl Sulfide van der Waals Complexes
(Elsevier, 1993-08)
The [mu]a and [mu]b electric dipole moment components of the Ne-OCS, Ar-OCS, and Kr-OCS van der Waals complexes were determined using Fourier transform microwave spectroscopy. The accuracy of these results was evaluated ...
Gated cardiac blood pool studies in atrial fibrillation: role of cycle length windowing
(Springer-Verlag, 1991-01)
Cycle length windowing is gaining increasing acceptance in gated blood pool imaging of patients with atrial fibrillation (AF). The goals of this study were: to assess differences of ejection fraction (EF) in AF with and ...
