Stimulation of nuclear protein synthesis in rat liver after phenobarbital administration
(Elsevier, 1970-07-13)
When a 40 min pulse of leucine-3H was administered to rats 2 hrs after 75 mg/kg of phenobarbital (Pb), there was a 70% increase above control in labeling of microsomal protein and of a nuclear protein fraction extracted ...
Indications of spatial relations among structures recognizing amino acids and Na+ at a transport receptor site
(Elsevier, 1970-07-27)
The orientation of the hydroxyl group on carbons 3 or 4 of proline, whether cis or trans, is decisive to the interaction between the amino acid and Na+ for a Na+-linked transport system of the pigeon erythrocyte and the ...
An analysis of models describing predator-prey interaction
(Wiley Subscription Services, Inc., A Wiley Company, 1970-05)
Mathematical models of the interaction between predator and host populations have been expressed as systems of nonlinear ordinary differential equations. Solutions of such systems may be periodic or aperiodic. Periodic, ...
Innervation of the receptors present at the various joints of the pereiopods and third maxilliped of Homarus gammarus (L.) and other macruran decapods (crustacea)
(Springer-Verlag, 1970-12)
This paper gives a full account of the number and structure of the chordotonal organs present at all joints between the coxopodite and dactylopodite of the pereiopods and 3rd maxilliped of the macruran Homarus gammarus L. ...
A radioimmunoassay for quantifying carbonic anhydrase isozymes in crude lysates
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1970-04)
A radioimmunoassay was developed for quantifying each of the two genetically distinct forms of primate carbonic anhydrase, carbonic anhydrases I and II, in unpurified lysates. Under the given experimental conditions, the ...
Induction of hepatic mitochondrial ferrochelatase by phenobarbital
(Elsevier, 1970-08-11)
Ferrochelatase, the catalyst for the last step in heme synthesis, is induced by chronic phenobarbital administration and this induction is prevented by the simultaneous administration of cycloheximide. This induction is ...
Structure and function of mammalian ribosomes , : II. Exchange of ribosomal subunits at various stages of in vitro polypeptide synthesis
(Elsevier, 1970-10-14)
1. (1) During in vitro polypeptide chain termination by rat or mouse liver polysomes, 80 s monosomes briefly dissociate into free subunits, presumably at the moment of their relase from the messenger. The subunits reassociate ...
A global strategy for nonlinear least squares
(Elsevier, 1970-02)
A general strategy for attacking problems in nonlinear least squares is developed. Parameters are classified as linear or nonlinear, depending on whether they appear linearly or nonlinearly in the functional expression ...
System theoretic analysis of models: Computer simulation of a living cell
(Elsevier, 1970-10)
In modeling a biological system for computer simulation one must often reduce the complexity of the system in accord with practical considerations of computer size and length of computation time. In our model of a living ...
