The in vitro effects of cortisol in regulating salmonid B cell functions were
investigated. B cells at three distinct stages of differentiation were examined for
cortisol sensitivity. B lymphocyte responses were examined 1) during the early stage
of the precursor, 2) during the intermediate stage of differentiation associated with
clonal...
Salmonid B lymphocytes were stimulated both in vivo and in vitro
and shown to produce antibody specific for the immunogen. A passive
hemolytic plaque assay was employed to demonstrate B cells producing
specific antibody. Characterization of plaque forming cells (PFCs)
involved sequential inhibition with a series of graded concentrations
of...
Currently little is known about the mechanisms and locations of
lymphocyte development in teleosts. In this study several aspects of the
underlying factors which govern B lymphocyte development in trout
were investigated which included: the isolation and characterization of
immunoglobulin heavy chain (IgH) genes, the recombination activating
genes 1 and...
The central purposes of this study were to review the
historical sources of David Kolb's formulation of experiential
learning theory, and to determine the effect and
application of Kolb's theory and Learning Style Inventory
as reflected in the literature between 1971 and 1990.
It was found that Kolb based his...
Chronic hepatitis B disproportionately affects Asian Americans. Although Asians make up only 4.2% of the total United States (U.S.) population, they account for more than half of those infected with hepatitis B. If left untreated, chronic hepatitis B could lead to cirrhosis, liver damage, and liver cancer. Studies show that...
The vitamin B₁₂ concentrations in both the water and sediments
of Klamath Lake were found to vary significantly during a
one-year period. The patterns of B₁₂ distribution were remarkably
similar among the three main sites. In all cases there was an extremely
sharp gradation in concentration in relation to depth...
Influenza A and Respiratory Syncytial Virus (RSV) are both enveloped, negative strand
RNA viruses which infect the respiratory mucosa of animals and humans. Despite
decades of research and development of antivirals and vaccines, both of these viruses
continue to be a major health concern throughout the world. The focus of...
Although much has been written describing the
various reactions to the origin of Species in America, the Mormon reaction to Darwinism has been largely ignored. This dissertation will recount the history of this reaction as exemplified by the life and works of B. H. Roberts. Roberts's intellectual pursuits early in...
