Assay of human plasma cortisone by liquid chromatography: normal plasma concentrations (between 8 and 10 a.m.) of cortisone and corticosterone
(Elsevier, 1993-04-02)
A high-performance liquid chromatographic method using ultraviolet detection to quantitate human plasma concentrations of cortisone simultaneously with cortisol and corticosterone is described. The method is based on the ...
A Continuous Spectrophotometric and Fluorometric Assay for Protein Tyrosine Phosphatase Using Phosphotyrosine-Containing Peptides
(Elsevier, 1993-05-15)
Two continuous assays for protein tyrosine phosphatases (PTPases) have been developed using phosphotyrosine containing peptide substrates. These assays are based on the marked differences in the spectra of the peptide ...
Generalized Unsöld theorem and radial distribution function for hydrogenic orbitals
(Kluwer Academic Publishers; J.C. Baltzer AG, Science Publishers ; Springer Science+Business Media, 1993-12)
A generalization of Unsöld's theorem is derived, giving the sum over both l and m for products of hydrogenic functions with given n . A generalized radial distribution function D n (r) is introduced and its properties ...
IGF receptor function and regulation in autocrine human neuroblastoma cell growth
(Elsevier, 1993-10-20)
Insulin-like growth factor-II (IGF-II) and its receptors (type I and II IGF receptors) are expressed in the nervous system in a tissue and developmentally specific manner. We have previously shown that SH-SY5Y human ...
Multivariable nonlinear control of a continuous polymerization reactor: An experimental study
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1993-12)
This experimental work concerns the multivariable nonlinear control of a continuous stirred-tank polymerization reactor. The globally linearizing control (GLC) method is implemented to control conversion and temperature ...
Isolation and purification of a squamous cell carcinoma of the head and neck-associated antigen identified by autologous antibody
(Elsevier, 1993-04-30)
We have previously shown that detection of autologous antibody activity to squamous cell carninoma of the head and neck many be augmented by dissociation in immune complexes. Western blot analysis with autologous antibody ...
Identity and some properties of the -threonine aldolase activity manifested by pure 2-amino-3-ketobutyrate ligase of Escherichia coli
(Elsevier, 1993-08-07)
2-Amino-3-ketobutyrate ligase catalyzes the reversible, pyridoxal 5'-phosphate-dependent condensation of glycine with acetyl CoA forming the unstable intermediate, 2-amino-3-ketobutyrate. Several independent lines of ...
Lactate Oxidation for the Detection of Mitochondrial Dysfunction in Human Skin Fibroblasts
(Elsevier, 1993-05-01)
To screen fibroblasts for defects in lactate/pyruvate oxidation, cells were grown to confluence in 25-cm2 flasks, rinsed, and incubated in glucose-free media containing 25 [mu]M L-lactate and 0.1 [mu]Ci [D,L-1-14C]lactate. ...
