Vibrational spectroscopic studies of -alternating valine peptides
(Elsevier, 1992-04-24)
Raman and infrared spectra of Boc-(Val--Val)n-OMe [(-Val)n], with n = 4, 6 and 8, were obtained in crystalline and solution states. Based on predictions from normal-mode calculations of a number of relevant single- and ...
Normal-mode analysis of infrared and Raman spectra of poly(vinyl fluoride)
(Elsevier, 1992-03-02)
Infrared and Raman spectra of samples of poly(vinyl fluoride) (PVF) have been recorded. The vibrational spectra have been analyzed by means of normal-mode calculations. A force field was derived by using 2-fluorobutane as ...
Rapid detection of human infections with fluorine-18 fluorodeoxyglucose and positron emission tomography: preliminary results
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-09)
The purpose of this study was to evaluate the feasibility of 2-[fluorine-18]fluoro-2-deoxy- d -glucose (FDG) and positron emission tomography (PET) for rapid detection of human infections. Eleven patients who were known ...
Rapid computation of the radiative absorption rate in the v3 mode of mesospheric and lower thermospheric ozone
(Elsevier, 1991-11)
We have developed an algorithm to calculate rapidly and accurately the rate (photons-molecule-1-sec-1) at which the ozone v3 fundamental band absorbs i.r. radiation in the terrestrial upper mesosphere and lower thermosphere. ...
Importance of intra-therapy single-photon emission tomographic imaging in calculating tumour dosimetry for a lymphoma patient
(Springer-Verlag, 1991-06)
The dosimetry for two, similarly sized tumours in a lymphoma patient being treated with non-bone marrow ablative, monoclonal antibody therapy is reported. The 45-year-old man was infused with 2.48 GBq (67 mCi) of 131 ...
Predictors of toxicity in treating patients with neuroblastoma by radiolabeled metaiodobenzylguanidine
(Springer-Verlag, 1994-01)
We searched for methods that would enable prescriptions of the maximum tolerable doses of iodine-131 metaiodobenzylguanidine (MIBG) and iodine-125 MIBG in the treatment of patients with neuroblastoma. We correlated doses, ...
Preliminary assessment of fluorine-18 fluorodeoxyglucose positron mission tomography in patients with bladder cancer
(Springer-Verlag, 1997-06)
The purpose of this study was to assess the feasibility of imaging of bladder cancer with fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) scanning. We studied 12 patients with histologically proven ...
Autoradiography-based, three-dimensional calculation of dose rate for murine, human-tumor xenografts
(Elsevier, 1993-11)
A Fast Fourier Transform method for calculating the three-dimensional dose rate distribution for murine, human-tumor xenografts is outlined. The required input includes evenly-spaced activity slices which span the tumor. ...
The design and performance of an ion trap storage--reflectron time-of-flight mass spectrometer
(Elsevier, 1994-02-24)
The design and performance of an ion trap storage--reflectron time-of-flight mass spectrometer (IT--RETOF MS) combination have been explored for detection of ions generated from both internal and external ionization sources. ...
Uptake of positron emission tomography tracers in experimental bacterial infections: a comparative biodistribution study of radiolabeled FDG, thymidine, l -methionine, 67 Ga-citrate, and 125 I-HSA
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-04)
The purpose of this study was to evaluate the localization of positron emission tomography (PET) tracers [2-deoxy-2-fluoro- d -glucose (FDG), thymidine, and l -methionine] in sites of bacterial infection, and to contrast ...
