A Comparison of Methods for the Determination of Dead Time in a Reversed-Phase High-Performance Liquid Chromatography System Used for the Measurement of Lipophilicity
Autor: R. K. Narra, D. P. Nowotnik
Publikováno v: Journal of Liquid Chromatography. 16:3919-3932
The dead time (void volume) of a reversed-phase system utilizing a column containing the divinylbenzene-styrene copolymer packing (PRP-1) was determined using candidate dead time markers, and two series of homologues, n-alkanols and n-alkyl benzenes.

Autor: W L, Rumsey, B, Kuczynski, B, Patel, A, Bauer, R K, Narra, S M, Eaton, A D, Nunn, H W, Strauss
Publikováno v: Journal of nuclear medicine : official publication, Society of Nuclear Medicine. 36(8)
This investigation evaluates the efficacy of a 99mTc-labeled nitroimidazole (BMS-181321) in identifying oxygen-deprived tissue in two canine models of myocardial ischemia.For both models (A and B), epicardial microvascular oxygen pressure (mPO2) was

Relationship between in vitro transendothelial permeability and in vivo single-pass brain extraction
Autor: J P, Pirro, R J, Di Rocco, R K, Narra, A D, Nunn
Publikováno v: Journal of nuclear medicine : official publication, Society of Nuclear Medicine. 35(9)
In vitro transendothelial permeability was compared to in vivo rat single-pass cerebral extractions to evaluate which method would best estimate the blood-brain barrier (BBB) permeability of several SPECT imaging agents.Six 99mTc complexes and seven

The single-pass cerebral extraction and capillary permeability-surface area product of several putative cerebral blood flow imaging agents
Autor: R J, Di Rocco, D A, Silva, B L, Kuczynski, R K, Narra, K, Ramalingam, S, Jurisson, A D, Nunn, W C, Eckelman
Publikováno v: Journal of nuclear medicine : official publication, Society of Nuclear Medicine. 34(4)
We have determined cerebral blood flow (CBF) and the single-pass cerebral extraction (E) of several putative agents for external imaging of CBF. Simultaneous measurements of blood flow and extraction were performed in 106 rats. For all agents, compar

Measurement of myocardial blood flow using a co-injection technique for technetium-99m-teboroxime, technetium-96-sestamibi and thallium-201
Autor: R J, Di Rocco, W L, Rumsey, B L, Kuczynski, K E, Linder, J P, Pirro, R K, Narra, A D, Nunn
Publikováno v: Journal of nuclear medicine : official publication, Society of Nuclear Medicine. 33(6)
We have compared apparent myocardial blood flow (MBFapparent) indicated by 99mTc-teboroxime, 96Tc-sestamibi and 201TI to true MBF indicated by radiolabeled microscopheres using a technique for the co-injection of four radionuclides in the same animal

Absorbed radiation dose to humans from technetium-99m-teboroxime
Autor: R K, Narra, T, Feld, A D, Nunn
Publikováno v: Journal of nuclear medicine : official publication, Society of Nuclear Medicine. 33(1)
Tissue distribution data obtained in nine normal volunteers were used to estimate the radiation dose to humans after intravenous administration of 99mTc-teboroxime (Cardiotec). Organ uptake as percent of injected dose was measured using quantitative

Technetium labeling of monoclonal antibodies with functionalized BATOs: 2. TcCl(DMG)3CPITC labeling of B72.3 and NP-4 whole antibodies and NP-4 F(ab')2
Autor: K E, Linder, M D, Wen, D P, Nowotnik, K, Ramalingam, R M, Sharkey, F, Yost, R K, Narra, A D, Nunn, W C, Eckelman
Publikováno v: Bioconjugate chemistry. 2(6)
BATO (boronic acid adduct of technetium dioximes) complexes, TcCl(dioxime)3BR, were prepared in which the boron substituent (R) was the protein-reactive 2-carboxy-4-phenyl isothiocyanate (CPITC). The 99Tc complexes, where the dioxime was either dimet
