5 kilodaltons). Its activation and inhibition spectra were similar to those previously determined for animal polymerase-beta. Therefore, since the structure of polymerase-beta shows significant evolutionary conservation in both plant and animal species and given strong functional correlations among species, polymerase-beta performs a vital role in plants in the repair of newly synthesized DNA just as it does in animal systems.

The acousticolateralis sensory system is characterized by a specific receptor cell type called the sensory hair cell and is found in all vertebrates. There are two types of hair cell sensory epithelia based on location: those of the inner ear, such as the organs for hearing and balance, and the lateral line system located within the epidermis. In mammals, including humans, loss or damage of the hair cells of the auditorysystem results in permanent hearing loss. However, this is not the case with birds and amphibians. Amphibians, with a lateral line system, are capable of replacing lost or damaged hair …

Adolescent Perceptions Of Risk-Taking Behaviors, Susan Matthews
Masters Theses & Specialist Projects
Adolescents often make adult decisions regarding their lifestyle and behavior with little support from their family and community. In this study the researcher examined the difference in risk-taking behaviors between genders and the role that families and communities play in reducing risk-taking behaviors. In the study I further analyzed self-reports of numbers of development assets those students reporting participation in high-risk behaviors. Method: Data were obtained from a sample of convenience of (N=82) 12th grade students. Behaviors and attitudes were examined using the Search Institute’s Profiles of Student Life survey. Results: Chi square was used to test for significant …
The Effects Of Managed Care On The Quality Of Dental Hygiene Care, Marybeth Magner
The Effects Of Managed Care On The Quality Of Dental Hygiene Care, Marybeth Magner
Masters Theses & Specialist Projects
Managed care has become a prominent mechanism for insuring dental care. Empirical research suggests that managed dental plans provide lower quality care to patients. However, few studies have specifically addressed the effects of managed care on the quality of dental hygiene care. Thus, in this study the researcher examines whether dental hygienists deliver a lower level of treatment to managed care patients than to those who are not subject to managed care. Questionnaire data were gathered from 193 members of the American Dental Hygienists' Association residing in the Chicago area. The primary independent variable, managed care, was measured with an …
Evaluation Of The Success Of Adoptive Versus Passive Transfer Of Immunity Against Trypanosoma Cruzi, Karen Powell
Evaluation Of The Success Of Adoptive Versus Passive Transfer Of Immunity Against Trypanosoma Cruzi, Karen Powell
Masters Theses & Specialist Projects
Several investigators have demonstrated an increased resistance to the protozoal parasite Trypanosoma cruzi (the causative agent of Chagas' disease) in highly susceptible C3H mice when maintained at an environmental temperature of 36°C. This increased resistance is manifested as delay in onset of parasitemia, decreased parasitemia, decreased pathology, and increased longevity with eventual clearing of the parasite from the bloodstream. In addition, this enhanced resistance has been shown to be an immunologic phenomenon and not due to the direct effects of elevated temperature on the parasite itself. To ascertain the possible contributions of humoral vs. cellular immunity to the above phenomenon, …

Masters Theses & Specialist Projects
The purpose of this study was to determine whether participation in a Family Resource\Youth Services Center New and Expectant Parenting Series had an impact on maternal and child health knowledge of parents and their future behavior choices. The study had two components. First, a telephone survey was conducted with 40 past program participants asking them nine questions concerning behavior and lifestyle choices in regards to child safety, breast or bottle feeding, immunizations, car seat use, etc. Secondly, thirty participants were given a pretest and posttest questionnaire. As a control group, there were 25 Lamaze class participants, who also completed the …
