Mechanism of cholesterol gallstone dissolution. II. Correlation between the effect of the alkyl amines as cholesterol gallstone dissolution rate accelerators and the degree of binding of the alkyl amines to the bile acid micelles
(Elsevier, 1980-03)
Recent studies have shown that cholesterol monohydrate pellet dissolution rates in real and synthetic bile systems are enhanced dramatically in the presence of small concentrations of amines, quaternary ammonium compounds, ...
Postnatal development of beta-endorphin immunoreactivity in the medulla oblongata of rat
(Elsevier, 1985-02)
Beta-endorphin (B-END) like immunoreactivity (i.r.) levels were measured by radioimmunoassay in the medulla oblongata of developing rats on postnatal ages P1-P42 at 7 day intervals, and in adult rats. From P1 to P42, B-END ...

Dopamine [beta]-hydroxylation in diabetes and diabetic autonomic neuropathy
(Elsevier, 1981-08)
Dopamine [beta]-hydroxylase (DBH) has been studied in healthy subjects and diabetic patients, some of whom had autonomic neuropathy. DBH was assayed by a recently described in vivo tritium release method (10,11). Dopamine ...
Phase II trial of N-methylformamide in advanced head and neck cancer
(Kluwer Academic Publishers; Martinus Nijhoff Publishers ; Springer Science+Business Media, 1987-06)
Eighteen patients with advanced epidermoid carcinoma of the head and neck were entered into a phase II trial of N-Methylformamide (NMF), 800 mg/M 2 IV daily for 5 days every 4 weeks. Seventeen patients had received prior ...
Dynamics of growth of silica particles from ammonia-catalyzed hydrolysis of tetra-ethyl-orthosilicate
(Elsevier, 1988-07)
The NH3-catalyzed formation of colloidal silica particles from tetra-ethyl-orthosilicate (TEOS) in methanol and ethanol is studied by means of light scattering and Raman spectroscopy. We find that the growth is characterized ...
Paired-ion high-performance liquid chromatographic assay for plasma choline
(Elsevier, 1980-03-14)
Choline was isolated from deproteinized plasma by cation-exchange chromatography. Isolated choline was directly converted to the 3,5-dinitrobenzoate derivative and was analyzed by paired-ion high-performance liquid ...
Agarose drop method for loading thin polyacrylamide gels
(Elsevier, 1982-11-01)
The gels (<1 mm) can be loaded conveniently, rapidly, and quantitatively by suspending the sample to be analyzed in a drop of agarose gel and simply placing the solidified drop on top of the stacking gel. With this ...
Vibrational analysis of peptides, polypeptides, and proteins. XVIII. Conformational sensitivity of the Α-helix spectrum: Α I - and Α II -Poly( L -alanine)
(Wiley Subscription Services, Inc., A Wiley Company, 1984-05)
The Α II -helix (φ = −70.47°, Ψ = −35.75°) is a structure having the same n and h as the (standard) Α I -helix (φ = −57.37°, Ψ = −47.49°). Its conformational angles are commonly found in proteins. Using an improved ...
