Coupling of dihydroriboflavin oxidation to the formation of the higher valence states of hemeproteins
(Elsevier, 1991-11-27)
SummaryThe reactions between hydrogen peroxide and hemeproteins have been coupled to the oxidation of dihydroriboflavin so as to provide a simple method for measuring the rate constant of hemeprotein peroxidation. ...
Quantitative evaluation of the pH profile in organic acid fermentations
(Wiley Subscription Services, Inc., A Wiley Company, 1991-01-20)
No Abstrct.
Selection of rare event cells expressing [beta]-galactosidase
(Elsevier, 1991-06)
The ACAS Interactive Laser Cytometer was used to screen and select mammalian cells in culture infected with a retrovirus construct containing the Escherichia coli lacZ and neomycin resistance genes. The product of expression ...
Amylin increases cyclic AMP formation in L6 myocytes through calcitonin gene-related peptide receptors
(Elsevier, 1991-06-14)
The cellular function of amylin is investigated in L6 myocytes, a rat skeletal muscle cell line. Both rat amylin and human amylin-amide acutely cause a dose-dependent increase in cyclic AMP formation in L6 myocytes. 100 ...
Evaluation of the mutagenic effects of SV40 in mouse, hamster, and mouse-human hybrid cells
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1991-07)
We have examined the ability of SV40 to induce changes in drug or temperature resistance in mouse, hamster, and mouse-human hybrid cells. SV40 induced a substantial increase of cells resistant to 5-bromodeoxyuridine + ...
Reproduction numbers and thresholds in stochastic epidemic models I. Homogeneous populations
(Elsevier, 1991-12)
We compare threshold results for the deterministic and stochastic versions of the homogeneous SI model with recruitment, death due to the disease, a background death rate, and transmission rate [beta]cXY / N. If an infective ...
Physiological changes during the adaptation of hybridoma cells to low serum and serum-free media
(Wiley Subscription Services, Inc., A Wiley Company, 1991-01-05)
Two murine hybridoma cell lines (167.4G5.3 and S3H5/Γ2bA2) were adapted to grow in low-serum and serum-free media by a weaning procedure. The changes in cell growth, metabolic, and antibody production rates with adaptation ...
Interleukin-1 induced gene expression of neutrophil activating protein (interleukin-8) and monocyte chemotactic peptide in human synovial cells
(Elsevier, 1991-01-31)
We report here that human synovial cells stimulated by interleukin-1[alpha] and interleukin-1[beta] express mRNA for both IL-8 (neutrophil chemotactic peptide) and monocyte chemotactic protein. IL-1 stimulated synovial ...
DNA insertions distinguish the duplicated renin genes of DBA/2 and M. hortulanus mice
(Springer-Verlag, 1991-03)
In a survey of inbred and wild mouse DNAs for genetic variation at the duplicate renin loci, Ren-1 and Ren-2 , a variant Not I hybridization pattern was observed in the wild mouse M. hortulanus . To determine the basis for ...
Development of pure culture biofilms of P. putida on solid supports
(Wiley Subscription Services, Inc., A Wiley Company, 1991-03-15)
Pseudomonas putida biofilms were developed on and biofilm accumulation rate data were obtained for the following two classes of support materials: charged surfaces and noncharged hydrophobic and hydrophilic surfaces. The ...
