Thermophysics of the lanthanide trihydroxides IV. The heat capacity of Ho(OH)3 from 11 to 350 K. Lattice and Schottky contributions
(Elsevier, 1981-11)
From values of the heat capacity of microcrystalline Ho(OH)3 determined by precise adiabatic calorimetry from 11 to 350 K, the Schottky contribution associated with the Stark splitting of the ground J-manifold (5I8) was ...
Purification of the catalytically active phosphorylated form of insulin receptor kinase by affinity chromatography with O-phosphotyrosyl-binding antibodies
(Elsevier, 1985-10)
The catalytically active, tyrosyl-phosphorylated form of insulin receptor kinase was isolated from human placenta by a procedure which exploits the propensity for the intact [alpha]2[beta]2 form of insulin receptor to ...
Dielectric breakdown characteristics of a high current metal vapor plasma
(Elsevier, 1987)
Time- and spatially-resolved spectroscopy is used to study the early-time spectral features of the plasmas produced by high-current, capacitive discharges through thin silver films. Spectra are compared for several support ...
Thermodynamics of thallium alkanoates II. Heat capacity and thermodynamic functions of thallium(I) n-heptanoate
(Elsevier, 1985-05)
The sub-ambient heat capacity of thallium(I) n-heptanoate is characterized by two sets of transitions between 262 and 301 K. The lowest transition (at 262.8 K) has a maximum Cp, m/R [approximate] 700. Next, a bifurcated ...
A convenient synthesis of substituted [gamma]-pyrones
(Elsevier, 1980)
An efficient and general synthetic method for various 2-mono- and 2,6-disubstituted [gamma]-pyrones has been developed. This utilizes the -acylation (70-85%) of [beta]-methoxy-[alpha],[beta]-enone lithium enolates by acid ...
Supercritical fluid jet expansions of polar aromatic carboxylic acids using simple derivatization with detection by resonant two-photon ionization
(Elsevier, 1988)
In this work simple derivatization is used as a means of enhancing the solubility of polar aromatic carboxylic acids in supercritical CO2 and N2O. The supercritical fluid is then expanded from 200 atm and 40[deg]C through ...
The captopril-digoxin multicenter resarch group study on the comparative steps of captopril and digoxin in patients with mildmoderate heart failure: Implications for therapy
(Kluwer Academic Publishers; Springer Science+Business Media, 1989-01)
It is argued that the basis of therapy in a patient with mild-to-moderate congestive heart failure should be a combination of a diuretic and a converting enzyme inhibitor, with the further addition of digoxin if necessary.
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 ...
