Cadmium metabolism in cdm/cdm mice
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1979-08)
The uptake and metabolism of cadmium by cadmium-susceptible ( +/+ ) and cadmium-resistant (cdm/cdm) strains of mice have been compared. These strains did not differ with respect to the quantitative uptake of cadmium into ...
Unstable electron pairing and the energy loan model of enzyme catalysis
(Elsevier, 1979-07-21)
A theory of enzyme catalysis is described which utilizes a thermodynamically consistent construction of a free energy diagram with different pathways for complex formation and decomposition. The switch to the decomposition ...
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. ...
Fruit production, migrant bird visitation, and seed dispersal of Guarea glabra in Panama
(Springer-Verlag, 1979-01)
The relationship between bird visitation and the size of the available fruit crop was studied at an understory tree ( Guarea glabra Vahl, Meliaceae) in the tropical wet forest of Barro Colorado Island, Panama Canal Zone. ...
Protein synthesizing systems from spores and vegetative cells of Bacillus cereus
(Springer-Verlag, 1979-06)
A system of polyphenylalanine synthesis was optimized for a comparison of the polymerizing activities of ribosomes from spores and vegetative cells of Bacillus cereus T. Ribosomes of both types react similarly, showing a ...
Aerobic and anaerobic energy expenditure during rest and activity in montane Bufo b. boreas and Rana pipiens
(Springer-Verlag, 1979-01)
The relations of standard and active aerobic and anaerobic metabolism and heart rate to body temperature ( T b ) were measured in montane groups of Bufo b. boreas and Rana pipiens maintained under field conditions. These ...
Neonatal administration of [beta]-endorphin produces "chronic" insensitivity to thermal stimuli
(Elsevier, 1979-11-12)
Male and female rat pups were injected with [beta]-endorphin, naloxone or a saline control solution during days 2-7 postnatally. At 90 days of age the rats were tested for analgesia with the tail flick test. Testing was ...
The basis for EDTA-stimulation of methemoglobin reduction in hemolysates of human erythrocytes
(Elsevier, 1979-12-28)
We have studied the stimulation by EDTA of methemoglobin reduction in hemolysates of human erythrocytes. The EDTA effect has been shown not to be the result of an allosteric interaction of EDTA with hemoglobin or the result ...
Estrogen receptor translocation and ornithine aminotransferase induction by estradiol in rat kidney
(Elsevier, 1979-07-27)
Injection of a hyperphysiological dose of 17[beta]-estradiol to the rat elicits a translocation of the cytoplasmic estrogen receptor in the kidney. This is followed, a few hours later, by an increase in the rate of ornithine ...
Identification and characterization of the cAMP binding proteins of yeast by photoaffinity labeling
(Elsevier, 1979-10-12)
Contrary to previous reports, we find the molecular weight of the major cAMP-binding protein in to be 54,000 daltons. A number of lower molecular weight proteins have also been identified and are believed to be breakdown ...
