Chemical characterization of a new Japanese variant of carbonic anhydrase I, CA I Nagasaki 1 (76 Arg→Gln)
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1979-06)
A new inherited variant of carbonic anhydrase I (CA I), designated CA I Nagasaki 1 (CA I NGS 1 ), was discovered during a survey of hemolysates from 5852 individuals from the cities of Hiroshima and Nagasaki in Japan. ...
Ultraviolet light-induced recombination
(Elsevier, 1973-12-10)
Stimulation of transduction in by ultraviolet irradiation of the transducing phage P1 requires the nuclease but not the product or DNA polymerase I. It is hypothesized that the first step in "normal" recombination can ...
Dispersal of sweet pignut hickory in a year of low fruit production, and the influence of predation by a curculionid beetle
(Springer-Verlag, 1977-09)
The rate at which fallen hickory nuts are removed from beneath the parent tree, and the effect on this rate of the seed predator Conotrachelus affinis , was studied in an oak-hickory forest in southeastern Michigan, USA, ...
L-kynurenine aminotransferase and L-[alpha]-aminoadipate aminotransferase. I. Evidence for identity
(Elsevier, 1975-01-20)
SummaryThe following observations strongly suggest that L-kynurenine aminotransferase (KAT) and L-[alpha]-aminoadipate aminotransferase (AAT) activities are associated with the same protein: 1. a similar distribution in ...
Dual control of lysogeny by bacteriophage P22: An antirepressor locus and its controlling elements
(Elsevier, 1975-02-05)
Two distantly linked clusters of genes on the Salmonella typhimurium phage P22 chromosome are involved in the control of lysogeny and superinfection immunity. One cluster consists of genes c1, c2, and c3, which are primarily ...
Analysis of an acoustic pacemaker in Strecker's chorus frog, Pseudacris streckeri (Anura: Hylidae)
(Springer-Verlag, 1974-03)
1. In breeding assemblages of Pseudacris streckeri the mating call of one individual often occurs immediately after that of another. Calling by one male then becomes entrained to that of another even though their intrinsic ...
Immunocytochemical analysis of cells in the pars tuberalis of the rat hypophysis with antisera to hormones of the pars distalis
(Springer-Verlag, 1975-03)
The objective was to acquire evidence regarding the secretory capacity of cells in the pars tuberalis of the rat pituitary by the application of immunocytochemical staining. For this purpose the conjugated antibody and ...
Studies on the xanthine oxidase activity of mammalian cells
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1973-04)
Xanthine oxidase in man is confined to but a few tissues and is absent from cultured cell strains. In rodents, however, the enzyme is more widely distributed among the tissues and can be demonstrated in most cell lines. ...
Axon regeneration across the site of injury in the optic nerve of the newt Triturus pyrrhogaster
(Springer-Verlag, 1977-04)
The process by which axons regenerate following a freeze injury to the optic nerve of the newt was analyzed by light and electron microscopy. Freezing destroys cellular constituents in a one millimeter segment of the nerve, ...
Factors affecting body temperatures of toads
(Springer-Verlag, 1978-01)
Factors influencing levels and rates of variation of body temperature ( T b ) in montane Bufo boreas boreas and in lowland Bufo boreas halophilus were investigated as an initial step toward understanding the role of natural ...
