Amino acid substitution and chemical characterization of a Japanese variant of carbonic anhydrase I: CA I Hiroshima-1 (86 Asp → Gly)
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1981-06)
An electrophoretic variant of red cell carbonic anhydrase I, designated CA I Hiroshima-1, has been observed in 12 apparently unrelated individuals during a survey of 13,019 individuals from the cities of Hiroshima and ...
A comparison of the responses of two tropical specialist herbivores to host plant patch size
(Springer-Verlag, 1986-03)
The effects of host plant patch size on the abundances of two specialist herbivores (the chrysomelid beetle, Acalymma innubum and the pentatomid bug, Piezosternum subulatum ) were investigated in a natural forest community ...
Environmental influences on mountain gorilla time budgets
(Wiley Subscription Services, Inc., A Wiley Company, 1988)
Data on the time budgets of mountain gorillas ( Gorilla gorilla beringei ) were collected during field studies in the Virunga Volcanoes region of Rwanda and Zaire. Focal sampling was used to determine the proportion of ...
Immunochemical studies on the metabolism of nitrosamines by ethanol-inducible cytochrome P-450
(Elsevier, 1985-04-30)
The ethanol-induced rabbit liver microsomal cytochrome P-450, P-450LM3a, has been shown previously to efficiently catalyze the demethylation of N-nitrosodimethylamine (NDMA) with a Km of 2.9 mM. Since the predominant Km ...
Multivariate statistical analysis of net diatom species distributions in the Southwestern Atlantic and Indian Ocean
(Springer-Verlag; Springer-Verlag GmbH & Co. KG, 1985-12)
Vertical net haul diatom assemblages from near South Georgia, and from between Africa and Antarctica, were examined and compared. Variation among South Georgia stations was examined by principal component, cluster and ...
The distribution of Heterotrissocladius oliveri Saether (Diptera: Chironomidae) in Lake Michigan
(Kluwer Academic Publishers; Dr W. Junk Publishers ; Springer Science+Business Media, 1986-02)
Fifty one chironomid species were identified from 504 samples collected at depths ranging 8 to 267 m in Lake Michigan, U.S.A. Heterotrissocladius oliveri Saether occurred in 32% of these samples and had an average abundance ...
Datura stramonium lectin: isolation and characterization of the homogeneous lectin
(Elsevier, 1981-07-20)
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 ...
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 ...
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 ...
