The incidence and duration of breast feeding were determined via telephone questionnaires from a sample of 95 women who delivered healthy infants during the month of September 1982, in the greater metropolitan area of Portland, Oregon. This sample was limited in that the women were married, predominately white, over 25 years of age, and well-educated. According to the literature, these factors have a positive correlation with the incidence and duration of breast feeding. Consequently, the reported values for the incidence of breast feeding in the hospital of 88 percent and the duration of breast feeding for six months of 44 percent is higher than reported values on a national level. However, the average duration of breast feeding by women who had weaned their babies at the time of this survey (6.2 weeks) is consistent with other studies. The information obtained from the questionnaires was used to measure the association between the incidence of breast feeding and the amount of information women received during their pregnancy; the duration of breast feeding and support system(s); and the relationship between the incidence and duration of breast feeding to the social factors of income, education, age, and race. Chi Square was the statistic used to compare the distribution, of responses among the three subgroups: women who breast fed only, formula fed only, or both breast and formula fed. Significant associations were not observed between the incidence of breast feeding and information or between the duration of breast feeding and support system(s). There was, however, an observed significant association between the incidence of breast feeding and the social factor of income. Additional findings revealed that women most likely to breast feed had themselves been breast fed as a baby, had breast fed their other children, and did not smoke cigarettes. Possible explanations for these results are discussed. / Graduation date: 1983

O MTA por apresentar boas propriedades físico-químicas e biológicas é indicado como material retrobturador. O objetivo deste trabalho foi avaliar, microscopicamente, a resposta do tecido subcutâneo de ratos frente à implantação de tubos de polietileno contendo novas formulações desse material: ProRoot MTA®, MTA Branco® contendo dois tipos de radiopacificadores e cimento Portland branco com óxido de bismuto. Foram utilizados 36 ratos (Rattus norvegicus), divididos em 12 animais para cada período experimental. Cada animal recebeu quatro implantes de tubos de polietileno, preenchidos com os materiais recém-espatulados de um lado, e do outro guta-percha (controle). Após 15, 30 e 60 dias os animais foram mortos e os espécimes foram preparados para análise microscópica. Os resultados mostraram inflamação crônica granulomatosa induzida pelos materiais, com intensidade moderada a discreta, e organização e espessamento de uma cápsula fibrosa com o passar do tempo. Os cimentos induziram respostas teciduais semelhantes, mesmo com radiopacificadores diferentes na composição. / Because of its good physicochemical and biological properties, MTA is indicated as a material for retrograde obturations. The aim of this study was to microscopically evaluate the response of the subcutaneous tissue of rats to the implantation of polyethylene tubes containing new formulations of this material: ProRoot MTA®, White MTA® containing two types of radiopacifiers, and white Portland cement with bismuth oxide. Thirtysix rats (Rattus norvegicus) were employed, which were divided into 12 animals for each study period. Each animal received 4 implants of polyethylene tubes filled with the recently prepared materials at one side, and gutta-percha at the other side (control). After 15, 30 and 60 days, the animals were killed and the specimens were prepared for microscopic analysis. The results demonstrated granulomatous chronic inflammation induced by the materials, of moderate to mild intensity, and organization and thickening of a fibrous capsule with time. The cements induced similar tissue responses, despite the presence of different radiopacifiers in their composition.

Everything She Does For You is a collection of original short fiction involving themes of love and loyalty. The stories center on characters living in the fictional town of Eastland, Maine. This collection culminates two years of creative experimentation as a fellow at the University of Miami. The current copy reflects my interest in fabulist and realistic fictions as well as my growing fascination with my state of origin, Maine, and the city in it that I know best, Portland.
