Multi-Assay Nutritional Metabolomics Profiling Of Low Vitamin A Status Versus Adequacy Is Characterized By Reduced Plasma Lipid Mediators Among Lactating Women In The Philippines: A Pilot Study, Catherine M. Johnson

Master's Theses

Background: A significant portion of lactating women in less developed countries have vitamin A (VA) deficiency. Lactation has substantial effects on a mother’s metabolism and VA is known to be needed in multiple biological processes, including growth, vision, immunity, and reproduction.

Objective: The objective of this pilot study was to utilize metabolomics profiling to conduct a broad, exploratory assessment of differences in plasma metabolites associated with low VA status versus adequacy in lactating women.

Methods: Plasma samples from lactating women who participated in a survey in Samar, Philippines, were selected from a cross-sectional study based on plasma retinol concentrations indicating …

Development Of A Pediatric Model Of Nafld In Neonatal Iberian Pigs, Gabriella Veronica Hernandez, Victoria Alice Smith, Morgan Coffin, Daniel Columbus, Matthew Burd, Kimberly Sprayberry, Mark Edwards, Daniel Peterson, Darin Bennett, Robert Fanter, Christopher Kitts, Michael La Frano, Margaret Rice, Douglas Burrin, Magdalena Maj, Rodrigo Manjarin

Master's Theses

The prevalence of non-alcoholic fatty liver disease (NAFLD) in children has increased over the past decades, creating a need for animal models that recapitulate the features of the pediatric disease. Iberian pigs have a leptin-resistant phenotype characterized by hyperleptinemia, hyperphagia, and extreme adipogenesis. We hypothesized that neonatal Iberian pigs fed a high fat high-fructose (HFF) diet will develop a pattern of liver injury resembling pediatric NAFLD. In addition, we sought to determine if a mixture of probiotics would prevent the disease. Animals were fed 1 of 4 diets containing (g/kg body weight × d) 0 g fructose, 11 g fat …

Associations Between Alcohol Consumption And Fasting Blood Glucose In Young Adults, Julie Ann Lucca

Master's Theses

Current research shows moderate alcohol consumption is associated with decreased risk of diabetes and excessive consumption or binge drinking can cause insulin resistance and diabetes. In 2010, diabetes was the seventh leading cause of death in the United Statesand was responsible for significant health complications: blindness, kidney failure, and limb amputations, and is a large national economic burden. Fasting blood glucose (FBG) is a tool used to help diagnose diabetes. Abnormally high FBG, ≥100 mg/dl, is indicative of diabetes and pre-diabetes. Few studies have observed diabetic prevalence among young adults or college students. Studying young adults can help provide added …

The Effects Of Age On Muscle Loss And Tissue-Specific Levels Of Nf-ĸb And Sirt6 Proteins In Rats, Tiev C. Laguire

Master's Theses

The objective of this study was to examine the influence of age on food intake, tissue and organ mass and NF-ĸB and SIRT6 levels in various tissues. The transcription factor, Nuclear Factor Kappa-B (NF-ĸB), is associated with both catabolic and anabolic pathways of muscle metabolism and may be involved in age-related muscle loss. SIRT6 is a member of the sirtuin family of proteins that function as protein lysine deacetylases and are associated with longevity in a number of organisms. Male Sprague-Dawley rats, aged 6 months (Adult) and 21 months (Old) were fed a commercially available diet for 10-17 days. Old …

The Regulation Of Liv-1 Mrna In Mda-Mb-231 Human Breast Cancer Cells And Its Association With E-Cadherin (Cdh1), Leelyn Chong

Master's Theses

LIV-1, the estrogen-regulated gene encoding a member of the ZIP family of zinc transporters (SLC39A6), has been implicated in both growth and metastasis of estrogen-receptor (ER) positive (+) and negative (-) breast cancer cells. In ER⁺ breast cancer cells, LIV-1 expression is induced by both estrogen and insulin. In embryonic cells, LIV-1 has also been negatively associated with the expression of the cell adhesion protein, E-cadherin (CDH1), thought to play a role in metastasis. In the present study, we investigated the regulation of LIV-1 and its relationship to CDH1 in MDA-MB-231 ER^- breast cancer cells. Cells were …
