Mining Public Microbiome Datasets to Identify Specific Microbial Taxa Associated with Anxiety-Related Disorders

Creator:: Martin, Austin N.
Abstract:: Over the last ten years, clinical, pre-clinical and animal studies have shown associations between the microbiota and neurological functions. Recent work by the scientific community on the gut-microbiome-brain axis have revealed that gut dysbiosis and specific microbial taxa are associated with a myriad of neurological conditions, such as autism spectrum...

A Historical Reflection of Cultural Factors Inhibiting American Healthcare Reform

Creator:: Leathers, James S.
Abstract:: Past healthcare reform has been blinded by the presence of competing philosophies and ideologies that ultimately yielded ineffective compromises or short-terms solutions. With the ever-shifting political and economic landscapes, the future of our nation’s healthcare is in great peril. This paper is a meta-analysis on obstructions to healthcare reform that...

A bacterial disease of the American shad (Alosa sapidissima)

Creator:: Rothman, Stanley
Abstract:: For the past six years a bacterial infection has been the cause of large losses of adult, spawning, American shad (Alosa sapidissima) in the Coos, Millicoma and Smith Rivers of Oregon. There was a sizable commercial fishery for shad in these rivers and losses of fish due to this infection...

“Don’t Choke ‘Em, Smoke ‘Em” : Lloyd “Tony” Stevenson and the Long Reach of History in “Post-Racial” Portland

Creator:: Ewens, Elise N.
Abstract:: Despite Portland’s progressive reputation, the response of city officials, police officers, and the community as a whole to the killing of the black man, Lloyd Stevenson, in 1985 at the hands of Portland police, demonstrates that the long racially discriminatory history of Oregon shaped public policy and popular thought about...

Susceptibility of select salmonids to Myxobolus cerebralis and effects of exposure on anadromous salmonids in Oregon

Creator:: Sollid, Sarah A.
Abstract:: Myxobolus cerebralis, a myxozoan parasite of salmonids, is the causative agent of whirling disease. The parasite is considered widespread throughout northeastern Oregon in the Grande Ronde and Imnaha River basins where threatened and endangered salmonid populations exist. The work presented in this thesis comprises several studies that assess the effects...

Studies on purification and characterization of an autolytic enzyme from cell walls of Bacillus subtilis

Creator:: Brown, Willie Claiborne
Abstract:: The purpose of this investigation was to purify and characterize the autolytic enzyme from cell walls of Bacillus subtilis 168. The crude enzyme was obtained by autolysis of purified cell walls in buffer at 37° C. Two purification methods were developed. The first involved fractional precipitation with ammonium sulfate. The...

Excretion of viable salmonellae by Salmonella-fed, chlorine-treated nematodes

Creator:: Smerda, Susan Mae
Abstract:: The role of nematodes (Diplogaster lheritieri Maupas 1919) as excretors of pathogenic organisms was studied. Salmonella typhi and Salmonella wichita were fed to nematodes for two days. The nematodes were surface sterilized with free chlorine. The activity of the chlorine was stopped by the addition of sodium thiosulfate followed by...

Persulfate oxidizable carbon as an index of organic pollution in wastewater

Creator:: Purkerson, L. Lee
Abstract:: Methods for the detection and measurement of waste materials in water have lagged far behind the many complex problems facing workers in the water pollution field. The present study introduces a new method for the detection and measurement of organic pollution in water. This new method, the persulfate oxidation, is...

Molecular Analysis of Environmental Water Samples as a Monitoring Method for the Fish Parasite Ichthyophthirius multifiliis

Creator:: Howell, Claire K.
Abstract:: Parasites are ubiquitous members of ecological communities, capable of contributing to the decline of vulnerable populations. Therefore, monitoring parasite level is a critical component for host management. Molecular tools, such as quantitative polymerase chain reaction (qPCR), can be valuable additions to monitoring protocols that assess parasitic disease risk to hosts....

Effect of mercury on β-galactosidase activity : possible relationship to lactose intolerance

Creator:: LaChance, Michele Collette
Abstract:: The ability of mercury to inhibit β - galactosidase activity from cell-free extracts of Streptococcus lactis, Escherichia colt and intestinal homogenates of hogs, female rats, and humans was studied. Mercuric acetate was added in vitro to all sources of β - galactosidase except for the rats, which were placed on...
