How A Healthy Population Acquires Nutrition And Exercise Information: A Mixed Methods Study, Sally J. Hillis
How A Healthy Population Acquires Nutrition And Exercise Information: A Mixed Methods Study, Sally J. Hillis
College of Education and Human Sciences: Dissertations, Theses, and Student Research
Faced with an overwhelming amount of available sources and different perspectives, researchers in the field of Nutrition and Health Sciences continually strive to identify key factors that shape a healthy lifestyle. Employing an exploratory sequential mixed methods design, phase one of this research utilized a constructivist grounded theory approach to develop a model explaining the process by which healthy individuals acquire nutrition and exercise information. Interested is studying a population identified by good nutrition and daily exercise, the researcher set the participant criteria to include daily consumption of 2-3 balanced meals, 45-60 minutes daily moderate-intensity exercise, and a normal BMI. …
Transport Of Bovine Milk Exosomes By Human Colon Carcinoma Caco-2 Cells And Rat Small Intestinal Iec-6 Cells, Tovah Wolf
Transport Of Bovine Milk Exosomes By Human Colon Carcinoma Caco-2 Cells And Rat Small Intestinal Iec-6 Cells, Tovah Wolf
Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research
We have reported that microRNAs (miRNAs, miRs) in bovine milk regulate human genes. In milk, many miRNAs are encapsulated in exosomes, thereby conferring protection against degradation and a pathway for intestinal transport of miRNAs. We hypothesized that the uptake of bovine exosomes in human intestinal colon carcinoma Caco-2 cells and rat primary small intestinal IEC-6 cells is mediated by endocytosis. Transport studies were carried out using fluorophore-labeled exosomes purified from bovine milk. The transport of bovine exosomes exhibited saturation kinetics at 37°C (Km= 55.5±48.6 µg/200 µL, Vmax= 0.083±0.057 ng exosomal protein x 81,750 cells−1 x …

Increased cell proliferation is a central key event in the mode of action for many non-genotoxic carcinogens, and quantitative cell proliferation data play an important role in the cancer risk assessment of many pharmaceutical and environmental compounds. Currently, there is limited unified information on assay standards, reference values, targeted applications, study design issues, and quality control considerations for proliferation data. Here, we review issues in measuring cell proliferation indices, considerations for targeted studies, and applications within current risk assessment frameworks. As the regulatory environment moves toward more prospective evaluations based on quantitative pathway-based models, standardiza- tion of proliferation assays will …
Steps In Metagenomics: Let’S Avoid Garbage In And Garbage Out, Jacques Izard
Steps In Metagenomics: Let’S Avoid Garbage In And Garbage Out, Jacques Izard
Department of Food Science and Technology: Faculty Publications
Is metagenomics a revolution or a new fad? Metagenomics is tightly associated with the availability of next-generation sequencing in all its implementations. The key feature of these new technologies, moving beyond the Sanger-based DNA sequencing approach, is the depth of nucleotide sequencing per sample.Knowing much more about a sample changes the traditional paradigms of “What is the most abundant?” or “What is the most significant?” to “What is present and potentially significant that might influence the situation and outcome?” Let’s take the case of identifying proper biomarkers of disease state in the context of chronic disease prevention. Prevention has been …

Social Contexts Of Infant Feeding And Infant Feeding Decisions, Ellen J. Schafer, Natalie A. Williams, Siri Digney, Marion E. Hare, Sato Ashida

Background: Infant feeding takes place within a network of social relationships. However, the social context in which infant feeding advice is received remains underresearched.
Objective: The objective of this study was to evaluate the social contexts of infant feeding by examining individual and relationship characteristics of mothers and network members associated with advice to exclusively breastfeed, exclusively formula feed, or use a combination of breast milk and formula.
Methods: Information about 287 network members was reported by 80 low-income mothers during a one-time survey. Characteristics of relationships associated with mothers receiving advice (exclusively breastfeed/formula feed, combination feed) from each network …
