Microflora Of Traditional Mexican Corn Masa And Its Effect On Folic Acid Degradation, Stephen J. Adolphson Dec 2012

Microflora Of Traditional Mexican Corn Masa And Its Effect On Folic Acid Degradation, Stephen J. Adolphson

Theses and Dissertations

Many Mexican women consume inadequate amounts of folic acid. Fortification of the corn tortilla could be an effective way to help increase the folic acid levels among the Mexican population. Previous studies have shown significant folic acid losses in fortified tortilla dough (masa) as it is held before baking. This loss in folic acid could be due to degradation by lactic acid bacteria naturally present in the masa. The microflora of traditionally made nixtamalized corn masa from six tortilla mills in Guadalajara, Mexico were isolated and characterized, and their effect on folic acid content was evaluated. Isolated bacteria were identified ...


Exposure To Dietary Selenium And Soy Isoflavones In Utero Provides Greater Protection Against Prostate Cancer Risk Factors In Tramp Mice Than Exposure Beginning At 6 Weeks, Heather Schofield Lindsay Jun 2012

Exposure To Dietary Selenium And Soy Isoflavones In Utero Provides Greater Protection Against Prostate Cancer Risk Factors In Tramp Mice Than Exposure Beginning At 6 Weeks, Heather Schofield Lindsay

Theses and Dissertations

Prostate cancer is the second most commonly occurring cancer in men in the United States. Generally, an extended period of time is needed for a mutation to develop into a full scale tumor. Because of this long latency period, lifestyle and environmental factors, such as diet, may play an important role in the development and progression of the disease. Diet is one factor that has been implicated in the risk for developing prostate cancer. We previously showed that diets high in soy isoflavones and selenium (Se) decreased androgen receptor expression and expression of androgen regulated genes in healthy rat prostates ...


An Investigation Of Current Practice In Management Rotations In Dietetic Internships, Emily K. Vaterlaus Mar 2012

An Investigation Of Current Practice In Management Rotations In Dietetic Internships, Emily K. Vaterlaus

Theses and Dissertations

Background: Leadership and management skills are critical to moving the dietetics profession forward; acquisition of those skills begins in the Dietetic Internship (DI). This study examined DI program components related to higher mean scores on the Foodservice and Management domain of the Registration Examination for Dietitians and compared Program Director and Preceptor perceptions of management rotation structure.

Methods: All 242 DI Program Directors (excluding sponsoring institution) received a 47-item electronic questionnaire. Directors provided contact information for up to three DI management rotation primary preceptors. Preceptors received a 35-item electronic questionnaire regarding their perception of interns' management skill development. Analyses included ...
