The new approach to wilderness preservation through benefit-cost analysis
(Elsevier, 1982-03)
Over the last 15 years, economists of Resources for the Future led by John Krutilla have been developing a new approach to wilderness preservation. This paper offers a concise exposition of their approach and adds a few ...
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 ...

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. ...
Catalytic properties of the resolved flavoprotein and cytochrome B components of the NADPH dependent generating oxidase from human neutrophils
(Elsevier, 1984-01-30)
The resolved flavoprotein and cytochrome b559 components of the NADPH dependent generating oxidase from human neutrophils were the subject of further study. The resolved flavoprotein, depleted of cytochrome b559, was ...
Response of Solidago canadensis clones to competition
(Springer-Verlag, 1988-11)
Transplants of ten Solidago canadensis clones were grown under high and low competition in the field to determine whether clones differed in survival, growth, and reproduction under natural conditions. Transplants had ...
Microstructural studies of sputter-deposited TiN ceramic films
(Elsevier, 1989-05-02)
A transmission electron microscopy study was undertaken to characterize the microstructures of TiN thin films that were sputter-deposited onto Cu-Be, alumina and glass substrates. There were no substantial microstructural ...
Effects of streptozotocin-induced diabetes on feeding stimulated by centrally administered opioid agonists
(Elsevier, 1989)
The potencies of several opioid agonists are reduced in diabetic animals and in animals made hyperglycemic via injections of glucose. In this report we examined the effects of streptozotocin-induced diabetes on the feeding ...
