Interest Group Influence On U.S. Congressional Committees: A Case Study Of The United States-Canada Free Trade Agreement, Laurel L. Hoffman
Interest Group Influence On U.S. Congressional Committees: A Case Study Of The United States-Canada Free Trade Agreement, Laurel L. Hoffman
Masters Theses
The impact of special interests on Congress has long been a matter for concern. A content analysis of testimony presented at 14 Congressional committee hearings on the United States-Canada Free Trade Agreement revealed that three broad categories of witnesses participated: business, government, and non-business. Total testimony for business and government were comparable, while non-business had fewer witnesses and less testimony. Government supplied more testimony in oral form, which was interpreted as a higher degree of participation than written testimony, predominantly supplied by business. There was little evidence of lobbying coalitions as measured by crossreferencing; witnesses rarely referred to anything but …
Isolation And Characterization Of The Triiodothyronine Regulatory Region Of The Fatty Acid Synthase Gene In Avian Species, Delfina Rivera Valencia
Isolation And Characterization Of The Triiodothyronine Regulatory Region Of The Fatty Acid Synthase Gene In Avian Species, Delfina Rivera Valencia
Masters Theses
Fatty acids are utilized for energy storage in the form of triglycerides or neutral fats. One way to regulate fatty acid biosynthesis is to regulate the activity of fatty acid synthase (FAS), the enzyme that catalyzes the reaction. Previous studies have shown that regulation of FAS activity and synthesis is regulated by the hormone triiodothyronine, T3, at the level of transcription. Thus, isolation and characterization of the promoter region o f the FAS gene will enable the identification of the thyroid hormone response elements (TREs). This study could shed light on the mechanisms on how this gene can …

A Comparison Of Percent Body Fat Calculated By Three Methods: Hydrostatic Weighing, Skinfolds, And Near Infrared Technique, James W. Hill
A Comparison Of Percent Body Fat Calculated By Three Methods: Hydrostatic Weighing, Skinfolds, And Near Infrared Technique, James W. Hill
Masters Theses
The purpose of this study was to determine the validity of the near infrared technique for assessing body composition. Hydrostatic weighing was used as the criterion measure to which skinfold technique and near infrared technique (as measured by the Futrex-5000) were compared. Two hundred subjects (115 females, 85 males) had their body composition assessed by the three techniques. The intraclass reliability of the Futrex-5000 was measured at r = .997. The Pearson product-moment correlation between hydrostatic weighing and the Futrex-5000 was r = .71 p < .01. The mean percent body fat derived from hydrostatic weighing was 19.3% compared to 21.6% for the Futrex-5000. At test indicated a significant difference between the mean percent body fats calculated by hydrostatic weighing and the Futrex-5000, t(160) = -5.21, p < .01. This study indicated that the Futrex-5000 was not as valid as either skinfold technique or hydrostatic weighing.

Leakage Of Solutes From Imbibing Seeds Of Supersweet Corn Cultivars That Differ In Tolerance To Low Germination Temperatures, Linda Kull
Masters Theses
Supersweet types of sweet corn (Zea mays L. var rugosa) with shrunken-2 endosperm are preferred by consumers because of their extra sweetness and postharvest retention of good flavor. However, their acceptance by growers is hindered due to reduced field emergence, especially in cold soils. This reduced emergence is related to seed quality. To examine differences between supersweet corn cultivars which are tolerant and sensitive to low temperatures, two cultivars were chosen based on their emergence in the field at low temperatures (10-15 C). 'Illini Gold' was chosen as the tolerant cultivar and 'Honey'n'Pearl' as the sensitive cultivar. Seeds …

A retrospective chart review was performed on 24 patients who were in the intensive care unit of a community teaching medical center, and required long-term ventilation of six days or more. After nine months of implementation of a standard nursing protocol, allowing for the intensive care nurses to become …
The Effects Of Selenate, Molybdate And Chromate On The Triiodothyronine Induced Enzyme Activity And Mrna Level For Both Fatty Acid Synthase And Malic Enzyme, Yuan Zhu
Masters Theses
In chick embryo hepatocytes in culture, triiodothyronine (T3) stimulates enzyme activity, mRNA level and transcription rate for both fatty acid synthase (FAS) and malic enzyme (ME). Recent evidence has demonstrated the effects of selenate, molybdate and chromate on various physiological processes. Little information, however, is available on the effects of these metal ions on the T3- regulated gene expression for FAS and ME.
In chick embryo hepatocytes incubated in a chemically defined medium, addition of sodium selenate (20 μM) coincident with T3 almost completely inhibited the T3-induced stimulation of FAS and ME activity and accumulation of their respective mRNA's. Neither …

An Analysis Of Dissolved Organic Compounds And Their Contribution To Iron Complexation In The Shallow Leachate Plume Of The West Kl Landfill Kalamazoo, Michigan, Eric Fahle
Masters Theses
High concentrations of dissolved iron are present in downgradient groundwater samples adjacent to the western border of the West KL Landfill. Analysis by Rudder (1988) of groundwater samples indicates oversaturation of selected iron oxides, iron sulfides and siderite in monitoring wells TW-4 and M3.
Previous research suggests that pyrogallol, gallic acid, tannic acid and similar organic compounds may retard the oxidation of ferrous iron in the shallow leachate plume of the West KL landfill (Rudder, 1988). Present research utilizing solid phase extraction, reverse phase high performance chromatography, Fourier transform IR spectrophotometry, UV/Visible spectrophotometry, and gas chromatography/mass spectroscopy indicate that pyrogallol, …

Copper Accumulation By Gizzard Shad (Dorosoma Cepedianum) In The Charleston Side Channel Reservoir, Mark T. Christ
Copper Accumulation By Gizzard Shad (Dorosoma Cepedianum) In The Charleston Side Channel Reservoir, Mark T. Christ
Masters Theses
Exposure to trace heavy metals is being extensively studied in relation to their adverse and toxic effects on organisms. Processes affecting compartmentalization, biogeochemical cycling, and transport of trace metals in ecological systems must be elucidated if the impact of trace metal releases on biota are to be understood. Because elemental cycles are often closely linked to hydrologic processes, freshwater and marine systems serve as both vectors and sinks for trace metals in the environment. The regular addition of a heavy metal into an aquatic ecosystem will undoubtedly increase its persistance for availability to the existing biota. Once in the environment, …

Cessation Of Chronic Ethanol Intake Reverses Ultrastructural Alterations In Ileal M Cells, Robert Rosback Eversole
Cessation Of Chronic Ethanol Intake Reverses Ultrastructural Alterations In Ileal M Cells, Robert Rosback Eversole
Masters Theses
Membranous (M) cells of the dome epithelium of ileal Peyer's patches have been shown to serve an antigen uptake function for mucosa associated lymphoid tissue. Hypergammaglobulinemia is a frequent accompaniment of chronic alcoholism in humans and the elevated antibody titers have been shown to be due in part to bacterial and dietary proteins. This study was conducted to demonstrate the morphological changes induced by chronic ethanol exposure in the ileal M cells in the rat.
Chronic ingestion of ethanol produces marked changes in the ultrastructure of M cells. All experimental animals showed distinct mitochondrial swelling with loss of matrix density, …

Tissue Culture In Rice (Oryza Sativa L. Subsp. Japonica Var. Lemont), Young M. Woo
Masters Theses
The purpose of this study was to obtain callus induction and subsequent plantlet regeneration from various explants of rice (Oryza sativa L. subsp. japonica var. Lemont). Callus induction occurred from the somatic cells of ovary wall, immature and mature embryos, immature endosperm, stem nodes, and seedlings. Plantlets were regenerated from embryo-, endosperm-, and stem node-derived calli on differentiation media. Stem nodes were the most responsive to callus induction. Requirements for optimal callus formation and plantlet regeneration differed from each culture. The study investigated the effects of cold treatment of explants, initial culture in darkness, media, and subculture for individual explant …
