Homologs of genes and anonymous loci on human Chromosome 13 map to mouse Chromosomes 8 and 14
(Springer-Verlag, 1995-04)
To enhance the comparative map for human Chromosome (Chr) 13, we identified clones for human genes and anonymous loci that cross-hybridized with their mouse homologs and then used linkage crosses for mapping. Of the clones ...
Postnatal ontogeny of acetylated and non-acetylated B-endorphin in rat pituitary
(Elsevier, 1983)
Extracts of the anterior lobe and intermediate lobe of postnatal (P) (Day P1, P7, P14, P21, P28, P35, P42) and adult male Spraque-Dawley rats were analyzed by both a Beta-endorphin (B-END) radioimmunoassay and a radioimmunoassay ...
Individual and population sex allocation patterns
(Elsevier, 1987-02)
A variety of sex allocation models is considered in which (i) the reproductive returns on investment in males differ from the returns on investment in females, (ii) the amounts of resources available for reproduction vary ...
There is no support for Jensen's hypothesis of nemerteans as ancestors to the vertebrates
(Kluwer Academic Publishers; Springer Science+Business Media, 1997-01)
Nemerteans (phylum Nemertea) have been viewed by mostzoologists as descended from, or closely related to,the flatworms. This view is based mainly on theirsupposedly acoelomate body. Their ancestry, however,is a point of ...
Identification and characterization of a human transthyretin variant
(Elsevier, 1987-10-14)
An apparent Mr variant of plasma transthyretin (TTR), previously detected using 2-D PAGE, is the first reported occurrence of this type of human TTR variant. We characterized the variant TTR to determine the nature of this ...
Experimental Management of a Group of Small Michigan Lakes
(Taylor & Francis GroupWiley Periodicals, Inc., 1938-01)
Eight small pit lakes, located in the Pigeon River State Forest, were considered to be ecologically suited to trout as determined by a physical, chemical, and biological survey of these lakes in 1931 and 1932. Four of the ...
Renewed interest in the polyphosphoinositides
(Elsevier, 1984-02)
The significance of the enhanced cellular phosphatidate and phosphatidylinositol turnover which occurs in response to specific extracellular messengers has been the subject of much interest and speculation. Until recently, ...
On the dynamic order of structured Escherichia coli growth models
(Wiley Subscription Services, Inc., A Wiley Company, 1987-04-20)
Reliable dynamic descriptions of cellular growth are important for many practical applications including bioreactor design and control. A chemically structured growth model of Escherichia coli has been formulated and ...
Effect of divalent metal ion binding on the Raman spectrum of ATP in aqueous solution
(Elsevier, 1970-01-23)
The apparent dissociation constants for the secondary H+ of HATP-3, CaHATP-1, MgHATP-1 and ZnHATP-1 were determined by studying the pH dependent frequency of a particular line in the Raman spectrum of ATP. We obtained the ...
