A reverse double-isotope enzymatic histamine assay: Advantages over single-isotope methods
(Elsevier, 1977-11-15)
High concentrations of codeine necessary to demonstrate histamine release from leukocytes interfere with histamine methylation, producing a concentration-dependent flattening of the histamine standard curves obtained from ...
Viroplasm and large virus-like particles in the dinoflagellate Gymnodinium uberrimum
(Springer-Verlag, 1979-09)
Virus-like particles (VLPs) measuring 385±5 nm in diameter are described in the freshwater dinoflagellate Gymnodinium uberrimum . The VLPs are found in association with, and “budding” from a vesicular viroplasmic area. A ...
The population genetics of parthenogenetic strains of Drosophila mercatorum
(Springer-Verlag, 1973-01)
A one locus model has been developed to describe parthenogenetic populations restoring diploidy by central fusion, terminal fusion and gamete duplication. It was found that in the absence of selection all populations become ...
Identification of [alpha] and [beta] tubulin in yeast
(Elsevier, 1976-06-07)
The similarity of yeast microtubular protein to the tubulins purified from other eukaryotic organisms has been open to question. This work involves the identification of two yeast proteins that resemble [alpha] and [beta] ...
A stochastic model for a closed biochemical system at equilibrium
(Elsevier, 1978-01-20)
This paper presents a stochastic model, a theoretical multi-variate probability function describing concentrations of reactants in a closed biochemical system at equilibrium. The theory applies to the complete range of ...
The lognormal distribution fits the decay profile of eukaryotic mRNA
(Elsevier, 1979-09-12)
A general program was written which simulates radioactive labeling of RNA . The program was used to determine the effect that different distributions of half-lives would have on the composite decay curve observed in a ...
Characterization of a new variant of human red cell carbonic anhydrase I, CA if London (Glu-102→Lys)
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1973-12)
A new inherited variant of red cell carbonic anhydrase I (CA I), designated CA If London, was discovered during a survey of 1615 individuals from London, England. No electrophoretic variants of the other isozyme of carbonic ...
A sex-limited serum protein variant in the mouse: Inheritance and association with the H-2 region
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1970-06)
An alloantiserum produced in the mouse has been used to detect an antigen which is present only in male serum from certain inbred strains of mice, e.g., DBA/2J, A/J, and BALB/c. Genetic tests reveal that the presence of ...
Mechanisms for the biodehalogenation of iodocompounds
(Elsevier, 1978-07-14)
The deiodination of [125I]-4-iodobiphenyl, [125I]-4-iodonitrobenzene and [125I]-4-iodoaniline was investigated. No deiodination was detected in rat thyroid homogenates. However, at least three biodeiodination mechanisms ...
Substitution of lysine for threonine at position 100 in human carbonic anhydrase Id Michigan
(Elsevier, 1973-04-02)
The position of the amino acid substitution in the human red cell carbonic anhydrase I variant, CA Id Michigan, has been determined by sequence analysis of the altered tryptic peptide. The threonine to lysine substitution ...
