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 ...
A Mixed Model-Based Variance Estimator for Marginal Model Analyses of Cluster Randomized Trials
(WILEY-VCH Verlag, 2007-06)
Generalized estimating equations (GEE) are used in the analysis of cluster randomized trials (CRTs) because: 1) the resulting intervention effect estimate has the desired marginal or population-averaged interpretation, and ...
A NMR Investigation of Structure and Allostery in the Hsp70 Chaperone System.
(2010)
The Hsp70 Chaperone system is a complex molecular machine composed of proteins. It is responsible for assisting in protein folding/refolding/processing and transport. Hsp70 proteins have been historically associated with ...
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 ...
Enterobiliary fistulae: A potential cause of a false-negative hepatobiliary study in the diagnosis of acute cholecystitis
(Springer-Verlag, 1985-02)
Cholescintigraphy has gained widespread acceptance in detection of acute cholecystitis (AC). Gallbladder (GB) visualization within 4 h effectively rules out A.C. with a high degree of specificity. We present a case of A.C. ...
Scatter modelling and compensation in emission tomography
(Springer-Verlag, 2004-05)
In nuclear medicine, clinical assessment and diagnosis are generally based on qualitative assessment of the distribution pattern of radiotracers used. In addition, emission tomography (SPECT and PET) imaging methods offer ...
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 ...
Infrared spectra of high polymers : Part IX. Polyethylene terephthalate
(Elsevier, 1959)
Infrared spectra of polyethylene terephthalate and three of its deuterated analogs have been obtained in the region of 70 to 3600 cm-1, polarized spectra having been obtained down to 330 cm-1. On the basis of analysis of ...
