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. ...
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 ...
Lead activates calmodulin sensitive processes
(Elsevier, 1983-09-05)
The effect of lead on two calcium sensitive processes was determined. Micromolar concentrations of lead successfully replaced calcium in the activation of calmodulin-sensitive phosphodiesterase and in the promotion of ...
Linkage of the structural gene for uroporphyrinogen I synthase to markers on mouse chromosome 9 in a cross between feral and inbred mice
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1982-08)
The Ups locus has been mapped to mouse chromosome 9 in a three-point cross. The observed gene order is centromere- Ups -15- Mpi-1 -22- Mod-1 . Ups is unlinked to Lv , which encodes the previous enzyme in the heme biosynthesis ...
Degenerative and regenerative changes in the trochlear nerve of goldfish
(Kluwer Academic Publishers; Chapman and Hall Ltd ; Springer Science+Business Media, 1984-08)
The features of unlesioned and lesioned trochlear nerves of goldfish have been examined electron microscopically. Lesioned nerves were studied between 1 and 107 days after cutting or crushing the nerve. 1. Unlesioned nerves ...
Comments on rarity and chaos, Thomas D. Rogers, math. biosci. 72:13-18 (1984)
(Elsevier, 1985-03)
Stimulation of fibroblast proliferation by thrombospondin
(Elsevier, 1989-08-30)
Thrombospondin purified from human platelets was examined for its ability to promote proliferation of human dermal fibroblasts. The results show that thrombospondin could stimulate the incorporation of [3H]thymidine by ...
Further studies on a hybrid cell-surface antigen associated with human chromosome 11 using a monoclonal antibody
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1983-07)
A monoclonal antibody has been obtained that recognizes an antigen encoded by human chromosome 11. We present evidence that this monoclonal antibody recognizes the same or a similar antigenic activity as that previously ...
Nuclear characteristics of cardiac myocytes following the proliferative response to mincing of the myocardium in the adult newt, Notophthalmus viridescens
(Springer-Verlag, 1988-09)
Amphibian cardiac myocytes are predominantly mononucleated and have been demonstrated to respond to injury with DNA synthesis and mitosis. The nature of this response with regard to nuclear number and ploidy is unclear. ...
