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 ...
Ganglion cell acuity in hooded rats
(Elsevier, 1982)
Previous measurements of retinal ganglion cell acuity in hooded rats have differed significantly from behavioral tests of visual acuity. One possible source of this discrepancy is examined--that light deprivation in early ...
Muscarine-sensitive voltage-dependent potassium current in cultured murine spinal cord neurons
(Elsevier, 1983-01-31)
Muscarine produced membrane depolarization and decreased membrane conductance of mouse spinal cord neurons in dissociated cell culture. When the neurons were voltage clamped, muscarine evoked inward currents which increased ...
Potassium-induced vascular relaxation in two kidney-one clip, renal hypertensive rats
(Springer-Verlag, 1983-01)
This study was designed to characterize potassium-induced relaxation in vascular smooth muscle in two kidneyone clip (2K-1C), renal hypertensive rats. Potassium-induced relaxation was evaluated in the isolated tail artery ...
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. ...
Transtubular bioreactor: A perfusion device for mammalian cell cultivation
(Kluwer Academic Publishers; Science & Technology Letters ; Springer Science+Business Media, 1989-01)
A transtubular mammalian cell perfusion chamber has been developed that allows separate delivery and control of medium and gas flow to the cells. The hydrodynamic and mass transfer characteristics of the reactor are studied ...
Mapping of the Saccharomyces cerevisiae CDC3 , CDC25 , and CDC42 genes to chromosome XII by chromosome blotting and tetrad analysis
(John Wiley & Sons, Ltd., 1987-12)
CDC3 , CDC25 and CDC42 were localized to chromosome XII by hybridizing the cloned genes to Southern blots of chromosomes separated by orthogonal-field-alternation gel electrophoresis. Meiotic tetrad analyses further ...
Purification and properties of an oxygen-evolving reaction center complex from photosystem II membranes : A simple procedure utilizing a non-ionic detergent and elevated ionic strength
(Elsevier, 1986-03-03)
A method is reported for the isolation of a highly resolved oxygen-evolving photosystem II reaction center preparation. This preparation can be separated from the more complex photosystem II membranes isolated by the ...
Cerebellar tRNA methyltransferases: A development study
(Elsevier, 1980-02-03)
Developmental patterns of homologous and heterologous tRNA methylation by cerebellar tRNA methyltransferases are described. The study revealed that: (a) homologous tRNA methylation results in the predominant formation of ...
