Carrier mediated transport of amino acids, small peptides, and their drug analogs
(Elsevier, 1987-12)
The oral absorption of amino acids, small peptides and their analogs has been studied in rats using single pass intestinal perfusion. The experimental data was analyzed using a modified boundary layer method permitting the ...
The use of silica gel impregnated glass fiber sheets in plasma estriol assays
(Elsevier, 1970)
The fluorimetric quantitation of nanogram amounts of estriol extracted from plasma is sometimes impaired by impurities which interfere with fluorescence. Instant thin-layer chromatography on silica gel impregnated glass ...
Vibrational analysis of crystalline diketopiperazine--II. Normal mode calculations
(Elsevier, 1984)
Based on our Raman and i.r. [1] data and assignments for DKP and five of its isotopic derivatives, we have refined an intramolecular force field in a non-redundant basis. This analysis shows that the cis peptide group may ...
A polarographic method for following the rates of cholinesterase-catalyzed hydrolyses of acetylthiocholine
(Elsevier, 1965-08)
A rapid and simple polarographic method for following the rates of the cholinesterase-catalyzed hydrolysis of acetylthiocholine and the rates of inhibition of this hydrolysis is described. This method has the advantage ...
Volatile combustion products of polycarbonate and polysulfone
(Wiley Subscription Services, Inc., A Wiley Company, 1972-04)
Thermal analysis of polycarbonate and polysulfone has shown each plastic to undergo a two-step decomposition, the first step involving production of high-boiling chain scission and volatile products, the second resulting, ...
An unmetasomatized source for the Malaitan alnoite (Solomon Islands): Petrogenesis involving zone refining, megacryst fractionation, and assimilation of oceanic lithosphere
(Elsevier, 1989-08)
The Malaitan alnoite contains a rich and varied megacryst suite of unprecedented compositional range. We have undertaken trace element and isotope modeling in order to formulate a petrogenetic scheme which links the host ...
Association of calmodulin inhibition, erythrocyte membrane stabilization and pharmacological effects of drugs
(Elsevier, 1982-11-08)
The present study was designed to determine whether there is an association of drug-induced inhibition of calmodulin functions, drug-induced membrane stabilization (protection against osmotic lysis), and pharmacological ...
Transtubular bioreactor: A perfusion device for mammalian cell cultivation
(Kluwer Academic Publishers; Science & Technology Letters ; Springer Science+Business Media, 1989-01)
A transtubular mammalian cell perfusion chamber has been developed that allows separate delivery and control of medium and gas flow to the cells. The hydrodynamic and mass transfer characteristics of the reactor are studied ...
The effects of chlorpromazine on psychomotor stimulant self-administration in the Rhesus monkey
(Springer-Verlag, 1972-06)
The effects of acute and chronic chlorpromazine treatment on psychomotor stimulant self-administration behavior in the Rhesus monkey were determined. Chlorpromazine treatment significantly increased the frequency of ...
