The cluster-tray method for rapid measurement of solute fluxes in adherent cultured cells
(Elsevier, 1981-08)
The use of an inexpensive and simple modification of Costar 24-well cluster trays is described in a rapid and reproducible method for measuring substrate fluxes in adherent cultured eukaryotic cells.
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 ...
Intraspecies Variability in the Esterases and Acid Phosphatases of Four Species of the Paramecium aurelia Complex 1
(Blackwell Publishing Ltd, 1983-02)
One hundred eighty-eight stocks of Paramecium primaurelia. P. biaurelia, P. tetraurelia. and P. octaurelia were grown axenically and screened for variation in four different esterases and acid phosphatase using starch gel ...
Characterization and expression of H-2I region gene products on bone marrow-derived macrophages
(WILEY-VCH Verlag GmbH, 1982)
Antigen-presenting macrophages (MΦ) were derived from day 7 cultures of bone marrow stem cells using L cell conditioned medium. The adherent bone marrow-derived macrophages (BMMΦ) were 100% esterase-positive, 95% positive ...
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 ...
Electrolysis-induced myocardial dysfunction : A novel method for the study of free radical mediated tissue injury
(Elsevier, 1986-07)
Oxygen-derived free radicals and other oxidizing species are thought to be involved in inflammation and ischemic tissue injuries. Recently, oxygen-derived free radicals also have been implicated in tissue injury of the ...
Unexpected complexity of the dm1 mutation revealed in the structure of three H-2D/L-related antigens
(Springer-Verlag; Springer-Verlag GmbH & Co KG, 1982-03)
The H-2L dm1 and H-2D dm1 MHC antigens of the B10.D2 ( H-2 dm1 ) mutant mouse strain (formerly known as M504 or H-2 da ) have been compared to the H-2L d and H-2D d antigens of the B10.D2 ( H-2 d ) mouse strain. L dm1 and ...
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 ...
CT and ultrasound in abscess detection at specific anatomic sites: A study of 198 patients
(Elsevier, 1987)
Records of 902 patients with possible abdominal abscess were reviewed and of these 198 had abscesses on at least one occasion imaged either with ultrasound (US) or computed tomography (CT). There were 235 episodes of either ...
Macronuclear persistence of sequences normally eliminated during development in Tetrahymena thermophila
(Wiley Subscription Services, Inc., A Wiley Company, 1985)
During conjugation in the ciliated protozoan, Tetrahymena thermophila , a somatic MAC-ronucleus develops from the germinal MICronucleus. Ten to 20 percent of the MIC genome is eliminated during this process. Three repetitive ...
