Chemiluminescence of nitric oxide: The NO (C2[Pi]-A2[Sigma]+) rate constant
(Elsevier, 1981-05)
A rocket borne scanning 1/4-m spectrometer was used to observe the night airglow between 1900 and 2300 A at a resolution of 15 A. An attitude control system oriented the payload horizontally near apogee (150 km) and pointed ...
The “water-ida”: A simple means to separate duodenal from gallbladder activity on cholescintigraphic studies
(Springer-Verlag, 1984-07)
In some 99m Tc-iminodiacetic acid studies, separation of the gallbladder from the duodenum can be difficult, despite multiple views. When faced with this problem, we have had the patient ingest 250 cc of tap water. This ...
Resonance enhanced multiphoton ionization of nucleosides by using pulsed-laser desorption in supersonic beam mass spectrometry
(Elsevier, 1989-04-01)
Pulsed-laser desorption is used as a means of volatilizing nucleosides into the gas phase for entrainment into a supersonic jet expansion. These species are then studied in a time-of-flight mass spectrometer by resonance ...
Femoral and obturator neuropathy secondary to retroperitoneal hemorrhage the value of the ct scan
(Elsevier, 1981)
A man developed signs of femoral and obturator neuropathy due to spontaneous retroperitoneal hemorrhage while taking anticoagulant drugs for suspected thrombophlebitis. The hemorrhage was demonstrated by CT scan. CT scans ...
Tomographic renal cortical scintigraphy: Correlation with intravenous urography, computed tomography, ultrasonography, angiography, and nuclear magnetic resonance imaging
(Springer-Verlag, 1985-11)
This study evaluates single-photon renal tomoscintigraphy (SPECT) in the evaluation of renal masses and correlates this modality, where indicated, with computed tomography (CT), ultrasonography (US), angiography (ANGIO) ...
Improved radioimmunolocalization of human tumor xenografts following subcutaneous delivery of monoclonal antibodies
(Springer-Verlag, 1988-01)
The localization of a radiolabeled murine monoclonal antibody reactive with choriocarcinomas to human choriocarcinoma xenografts following intravenous and subcutaneous injection was evaluated by gamma scanning and tissue ...
Centrifugal distortions in molecules: An ab initio approach with application to phosphine
(Elsevier, 1988-12)
Our procedure for employing analytic gradients of ab initio potential energy hypersurfaces in the description of centrifugally distorted molecules is applied to a symmetric top, namely phosphine. Quartic centrifugal ...
The effect of specimen processing on radiolabeled monoclonal antibody biodistribution
(Springer-Verlag, 1984-08)
Monoclonal antibodies are assuming increasing importance in experimental and clinical medicine. Generally, tissue biodistribution studies in animals precede human studies. To investigate a concern of ours that varying ...
Tunable laser study of the [nu]10 + [nu]11 band of cyclopropane
(Elsevier, 1980-06)
Diode laser measurements of the [nu]10 + [nu]11 (ltot = +/-2) perpendicular band of cyclopropane have led to the assignments of roughly 600 lines in the 1880-1920-cm-1 region. Most of the spectra were recorded and stored ...
Increased genital uptake of 99m Tc red blood cells: A potential cause of false-positive studies for gastrointestinal bleeding
(Springer-Verlag, 1984-05)
We have recently seen several 99m Tc labeled red blood (Tc-RBC) cell studies, for the localization of gastrointestinal (GI) bleeding, which were difficult to interpret because of increased activity in the low abdomen, which ...
