Vibrational analysis of peptides, polypeptides and proteins. XII—fermi resonance analysis of the unperturbed ND stretching fundamental in polypeptides
(John Wiley & Sons, Ltd., 1982-04)
We have obtained the spectrum of β‐poly(L‐alanine‐ND), and find three bands in the ND stretching region. By comparison with Fermi resonance analyses of deuterated derivatives of polyglycine I as well as with α‐poly(L‐alanine‐ND), ...
Inverse Raman spectroscopy of bilirubin and its ditauride
(John Wiley & Sons, Ltd., 1984-08)
The inverse Raman spectrum of bilirubin and bilirubin ditauride were measured under pre‐resonant conditions. Spectra in chloroform and dimethyl sulfoxide were assigned by comparison with model compounds and on the basis ...
The (F)utility of the thallium-201 quantitative lung/myocardial ratio in the detection of coronary artery disease
(Springer-Verlag, 1986-01)
Exercise-induced increases in pulmonary uptake of thallium-201 ( 201 Tl) have been associated with exercise-induced myocardial dysfunction. To evaluate this phenomenon more replicably, a quantitative semi-automated computer ...
Computed tomography of malignant tumors of the osseous pelvis
(Elsevier, 1983)
The medical records, conventional radiographs, bone scans and pelvic CT scans obtained in 50 consecutive patients with malignant lesions involving the osseous pelvis were retrospestively reviewed. In 21 patients with primary ...
Analysis of the low temperature fluorescence and phosphorescence spectra of p-difluorobenzene
(Elsevier, 1983-11)
The low temperature fluorescence spectra (4.2 K) of solid solutions of p-difluorobenzene-h4 (pDFB-h4) and -d4 have been recorded and analyzed. The absence of fluorescence from vibrationally excited states at 4.2 K eliminates ...
The appended curve technique for deconvolutional analysis —method and validation
(Springer-Verlag, 1988-09)
Deconvolutional analysis (DCA) is useful in correction of organ time activity curves (response function) for variations in blood activity (input function). Despite enthusiastic reports of applications of DCA in renal and ...
Scintigraphic detection of sinusitis
(Springer-Verlag, 1988-11)
Radionuclide scintigraphy is useful in the diagnosis of sinusitis. Three cases are described, using different radionuclide agents ( 99m Tc-MDP, 67 Ga-citrate and 111 Inleukocytes) in which sinusitis was discovered, though ...
Magnetic resonance imaging of systemic venous anomalies
(Elsevier, 1986)
Seven cases of anomalous development of the systemic great veins were found in the first 18 months of adult body imaging with a 0.15 T resistive magnetic resonance unit. Comparison was made with CT. In most cases, CT and ...
The absorption and magnetic circular dichroism spectra of matrix-isolated Os18O4 and Os16O4
(Elsevier, 1984-09)
Matrix absorption and magnetic circular dichroism studies on Os16O4 and Os18O4 have been carried out to clarify the number of electronic transitions present in the region. The spectra show that the irregular vibrational ...
Gestational trophoblastic neoplasia: Computed tomographic appearance
(Elsevier, 1983)
The authors present the computed tomographic findings in a patient with malignant gestational trophoblastic neoplasia. No similar case has been described on computed tomography. The interesting aspects of the case and a ...
