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 ...
The effects of feeding on heart activity in the terrestrial slug, Limax maximus : central and peripheral control
(Springer-Verlag, 1985-07)
The role of the central nervous system (CNS) in the modulation of heart activity induced by feeding was investigated in the terrestrial slug, Limax maximus . Intact slugs and semi-intact preparations were used to examine ...
Sensitization to stress: The enduring effects of prior stress on amphetamine-induced rotational behavior
(Elsevier, 1985-09-16)
In rats with a unilateral 6-OHDA lesion of the substantia nigra exposure to footshock or immobilization stress produced a long-lasting enhancement in the rotational behavior evoked by a subsequent injection of amphetamine. ...
Comments on rarity and chaos, Thomas D. Rogers, math. biosci. 72:13-18 (1984)
(Elsevier, 1985-03)
Properties of the tryptophan residue in rabbit liver microsomal cytochrome P-450 isozyme 2 as determined by fluorescence
(Elsevier, 1985-04-30)
Cytochrome P-450 isozyme 2 from rabbit liver microsomes fluoresces upon excitation at 295 nm due to the single tryptophyl residue (Trp121) in the protein. The fluorescence spectrum, which is not altered by the presence of ...
Cell proliferation-associated expression of a recently evolved isozyme of triosephosphate isomerase
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1985-04)
An electrophoretically unique, thermolabile isozyme of triosephosphate isomerase (TPI; EC 5.3.1.1) accounts for 10–30% of the enzymatic activity in a range of mitotically active human cells and tissues. This type 2 form ...
Solubilization of hen brain neurotoxic esterase in dimethylsulfoxide
(Elsevier, 1985-10-15)
Neurotoxic esterase is the putative site of initiation of organophosphorus-induced neuropathy. The protein is membrane-associated and will thus require solubilization before it can be purified. Its enzymic activity was ...
Prey selection by the copepod Diacyclops thomasi
(Springer-Verlag, 1985-03)
1. Adult females of the predaceous copepod, Diacyclops thomasi , consistently selected for the soft-bodied rotifers Synchaeta pectinata, Polyarthra major and P. remata when presented various combinations of 8 rotifer species ...
Numerical parameter identifiability and estimability: Integrating identifiability, estimability, and optimal sampling design
(Elsevier, 1985-12)
We define two levels of parameters. The basic parameters are associated with the model and experiment(s). However, the observations define a set of identifiable observational parameters that are functions of the basic ...
Hyperbaric pressure of 51 atmospheres is without effect on the depression of oxygen uptake in kidney tissue culture produced by halothane
(Elsevier, 1985-09-30)
Although anesthetized animals are awakened when subjected to increased pressure, compression does not result in antagonism of all phenomena associated with these drugs. It has recently been demonstrated that halothane's ...
