Congruent Avian Phylogenies Inferred from Mitochondrial and Nuclear DNA Sequences
(Springer-Verlag; Springer-Verlag New York Inc., 2003-07)
Recent molecular studies addressing the phylogenetic relationships of avian orders have had conflicting results. While studies using nuclear DNA sequences tend to support traditional taxonomic views, also supported by ...
The bicoid -related Pitx gene family in development
(Springer-Verlag; Springer-Verlag New York Inc., 1999-02)
Datura stramonium lectin: isolation and characterization of the homogeneous lectin
(Elsevier, 1981-07-20)
Development of crystalline inclusions (“ergosterol crystals”) in Neurospora crassa
(Springer-Verlag, 1976-09)
Development of crystalline inclusions (“ergosterol crystals”) in “snowflake”, a morphological mutant of Neurospora crassa has been examined. The inclusions which arise in membranebound organelles appear as electron dense ...
Effectiveness factor calculations for immobilized enzyme catalysts
(Wiley Subscription Services, Inc., A Wiley Company, 1973-09)
The steady state, nonlinear diffusion equations which describe reactions in constrained enzyme solutions are of great interest in many biological and engineering applications. As in other types of nonlinear differential ...
Evaluation of time-average dispersion models for estimating pheromone concentration in a deciduous forest
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1984-07)
The Sutton and more recent Gaussian plume models of atmospheric dispersion were used to estimate downwind concentrations of pheromone in a deciduous forest. Wind measurements from two bivane anemometers were recorded every ...
Rapid protein release from Escherichia coli by chemical permeabilization under fermentation conditions
(Wiley Subscription Services, Inc., A Wiley Company, 1992-03-25)
Overall protein release greater than 75% in less than 1 h can be attained by exposing exponentially growing Escherichia coli cells to 0.4 M guanidine plus 0.5% Triton X-100 at 37°C in medium. Cell growth stops immediately ...
Chronic haloperidol treatment increased calcium-dependent phosphorylation in rat striatum
(Elsevier, 1982-01-04)
In previous studies, we observed that when rats were chronically treated with haloperidol, there was a significant increase of calmodulin activity in their striatal membranes. Calmodulin is knwon to modulate calcium-dependent ...
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 ...
