The patterns of cell proliferation in the choroid plexuses of
embryonic and post-natal hamsters were studied by means of auto-radiography
(H³-thymidine). In addition, the PAS technique was
used to determine the times of first appearance, relative amounts,
location, and times of disappearance of glycogen free the plexuses.
Many mitotic figures...
The population dynamics and reproductive strategies of the
stream snail Oxytrema silicula were examined in four coastal streams
in Oregon representing a small first order stream, a wider third
order stream and a fourth and sixth order stream. Samples were
taken in each type of stream bottom for each stream...
A method to measure consumers' housing consumption and
investment attitudes according to various dimensions was initiated.
In addition, construct validity of the measurement instrument was
initiated through use of personal variables.
Two scales were developed to measure homeownership consumption
and investment attitudes. The dimensions of homeownership consumption
and investment found...
Pacific Coast band-tailed pigeons (Columba fasciata) have declined markedly
during the past several decades. Despite implementation of increasingly restrictive
hunting regulations, populations have shown minimal signs of recovery. I radio-marked
127 adult band-tailed pigeons in the central Oregon Coast Range in April-May of 1993-95
to document nesting chronology and productivity,...

5'-Deoxy-5'-methylthioadenosine phosphorylase catalyzes
the phosphorolytic cleavage of 5'-deoxy-5'-methylthioadenosine
to form 5'-deoxy-5'-methylthioribose-1-phosphate and
adenine in mammalian cells and plays an important role in
methionine and purine salvage. The enzyme is abundant in
normal tissues and in cell lines derived from normal cells.
However, several malignant tissues and cell lines have been...
A method for predicting the harvest of commercial Dungeness
crab (Cancer magister) one year in advance of the fishing season is
described. The technique is based on the hypothesis that the relative
abundance of sub-legal crabs one year is directly proportional to the
harvest of legal crabs the following year....
