Isolation of Sets of a, α, a/α, a/a and α/α isogenic strains in Saccharomyces cerevisiae
(Springer-Verlag; Springer-Verlag GmbH & Co. KG, 1982-10)
A simple, quick technique for isolating sets of a, α, a/α, a/a and α/α isogenic strains of the yeast, Saccharomyces cerevisiae is described. Isogenic a/α diploids arise in haploid populations by a rare heterothallic switch ...
Overlapping deficiencies refine the map position of the sex-linked actin gene of Drosophila melanogaster
(Springer-Verlag, 1982-10)
A 3 H-labelled actin-specific probe was hybridized to Drosophila melanogaster X chromosomes heterozygous for deficiencies in the 5C region. The results suggest that the sex-linked actin gene resides in the overlap region ...
Oxidative metabolism of xenobiotics during pregnancy: Significance of microsomal flavin-containing monooxygenase
(Elsevier, 1982-12-31)
Pregnancy related changes in oxidative metabolism of model substrates were examined in CD1 mice. As compared to nonpregnant females, a significant decrease in the hepatic microsomal aminopyrine-but not in dimethylaniline ...
A morphometric analysis of algal response to low dose, short-term heavy metal exposure
(Springer-Verlag, 1982-06)
Three algae, Melosira granulata, Fragilaria capucina , and Anacystis cyanea , collected as part of a natural phytoplankton assemblage were found to differ in their cytological responses to low dose short-term exposure to ...
5' termini of polyoma virus early region transcripts synthesized in vivo by wild-type virus and viable deletion mutants
(Elsevier, 1982-08-05)
The 5' termini of polyoma virus early region transcripts synthesized during the productive infection of permissive mouse cells by wild-type or tsa virus, and those expressed in a variety of transformed rodent cell lines, ...
Quantitative character dynamics: Gametic model
(Elsevier, 1982-12)
A gametic model of quantitative character dynamics is introduced that fills the gap between the two existing models: genic and zygotic/phenotypic. In this model, a gamete is treated as the elementary unit of evolution, all ...
Characterization of two new electrophoretic variants of human triosephosphate isomerase: Stability, kinetic, and immunological properties
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1982-02)
Two new electrophoretic variants of human triosephosphate isomerase (TPI) have been partially purified and characterized. The TPI Manchester variant, a cathodally migrating electrophoretic allozyme identified in an individual ...
Stereospecific binding of 3H-phencyclidine in brain membranes
(Elsevier, 1982-06-21)
Phencyclidine (PCP) displaceable binding of 3H-PCP to glass-fiber filters was eliminated and total binding markedly reduced by initial treatment of the discs with 0.05% polyethyleneimine. Assessed with treated filters, ...
