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 …

The R Value At Vo2 Max During Maximal Graded Exercise Treadmill Tests Of Coronary Artery Diseased And Nondiseased Subjects, Sherry S. Williams

Masters Theses

This study examined the R value at VO2 max during maximal graded treadmill exercise tests to determine if it was a reliable indicator of VO2 max and could therefore be used as a test termination criterion. The subjects in this study were 160 coronary artery diseased (CAD) patients and 170 nondiseased individuals. Data were collected from existing stress test records. The R value was also analyzed to determine if proportions of diseased and nondiseased subjects were the same. The time it took 100 CAD patients to reach VO2 max and exhaustion once R rose above 1.00 was also examined.

Mate Choice: Investigation Of Mating Preference For Siblings Versus Nonsiblings In The Solitary Vespid Wasp Euodynerus Foraminatus, Omoury A. Chambegga

Masters Theses

Caged wasps of Euodynerus foraminatus were given a choice of a sibling or a nonsibling for mates. Two types of experiments were conducted: female choice and male choice. For female choice experiments one female, a sibling male, and an unrelated male were introduced into an observation cage. For male choice experiments one male, a sibling female, and an unrelated female were introduced into an observation cage. Females preferred to mate with siblings, but males mated randomly with regard to family relationship.

Fixed-Ratio Size As A Determinant Of The Development Of Tolerance To Morphine, Mark J. Nickel

Masters Theses

The acute and chronic effects of morphine were examined in pigeons exposed to a multiple schedule with fixed ratio 5, 25, and 125 components. Acute exposure to morphine (0.56-10.0 mg/kg) resulted in rate reductions under each component when the dose was 1 mg/kg or higher. With chronic exposure to 5.6 mg/kg, tolerance to the rate-reducing effects of morphine was evident under each fixed ratio component. The development of tolerance was determined to some extent by fixed-ratio size, a result similar to earlier findings with cocaine.

The Suburban Rice Farmers: Economic And Cultural Change In Japan, Makoto Chiwaki

Masters Theses

The world economic situation is forcing the Japanese government to initiate policies designed to make its rice farming industry more competitive on the world market. These new policies, along with the growth of Japan's urban areas, are causing certain stresses on the cultural institution called bunke among the part-time rice farmers in the Kaizuka region of Chiba City, Japan.

An ethnographic study of these farmers reveals that the farmers of the Kaizuka region have responded to recent changes differently from the farmers of other regions because of their cultural institutions and traditions.

Fountain Solution Ph And Conductivity Changes Caused By Paper Extractables During Offset Printing, Douglas E. Cox

Masters Theses

Economical and environmental issues are causing papermakers to change from the traditional acid papermaking process to neutral and alkaline papermaking processes. Also, offset printers are changing from traditional acid type fountain solutions, with or without alcohol, to: (a) neutral, (b) alkaline, and (c) acid with alcohol substitute type fountain solutions. The interaction between these new papermaking variables and fountain solutions and their effect on printability needs to be investigated.

The pH, conductivity, and contact angle changes of five different offset printing fountain solutions were monitored during offset printing press trials on acid, neutral and alkaline basestocks.

The results indicate that …
