Cytochrome P450 Monooxygenase-Mediated Lipid Metabolism In Obesity And Colon Tumorigenesis, Weicang Wang Oct 2019

Cytochrome P450 Monooxygenase-Mediated Lipid Metabolism In Obesity And Colon Tumorigenesis, Weicang Wang

Doctoral Dissertations

Colon cancer is a major public health issue: it is expected to have 140,250 new cases and 50,630 deaths during 2018, making colon cancer the third most common type of cancer and the second leading cause of cancer death in the United States. Obesity is associated with enhanced colonic inflammation, which is a major risk factor of colorectal cancer. Currently, more than 35% of adults and nearly 17% of children are obese. Considering the obesity and colon cancer epidemic in the United States, there is an urgent need to identify novel therapeutic targets for obesity and colon cancer ...


Effects Of Permethrin, A Pyrethroid Insecticide, On Glucose And Lipid Metabolism, Xiao Xiao Jul 2017

Effects Of Permethrin, A Pyrethroid Insecticide, On Glucose And Lipid Metabolism, Xiao Xiao

Doctoral Dissertations

Over the last few decades, the decline of using organochlorine and organophosphorus insecticides has partially contributed to the rising utilization of newer synthetic insecticides, which are considered as less harmful and more environmental friendly than the older generation of insecticides. Pyrethroid insecticides are one of the newer insecticide classes reported with better biodegradability and low mammalian toxicity without sacrificing its insecticidal efficacy. Permethrin is one of the most widely used pyrethroid insecticides with structural similarity with natural pyrethrin insecticide from the flowers of Chrysanthemum cinerariifolium. Since its introduction in the 1970’s, permethrin has been extensively used in medicine, military ...


Gestational Diabetes, Infant Feeding Practices, And Early Indicators Of Obesity Risk In A Sample Of Mother-Infant Dyads In The U.S., Kimberly N. Doughty Nov 2015

Gestational Diabetes, Infant Feeding Practices, And Early Indicators Of Obesity Risk In A Sample Of Mother-Infant Dyads In The U.S., Kimberly N. Doughty

Doctoral Dissertations

Research suggests that the trajectory to obesity and its associated metabolic disorders begins early in life. Prenatal exposure to maternal gestational diabetes mellitus (GDM) is associated with increased risk, while breastfeeding is associated with reduced risk. Breastfeeding may influence obesity risk by preventing rapid postnatal weight gain. Mothers with gestational diabetes may not breastfeed as intensely as healthy mothers, potentially exacerbating the risk to their infants. We conducted three distinct investigations related to gestational diabetes, breastfeeding, and infant weight gain. All used data from the U.S. Infant Feeding Practices Study II. Multivariate logistic regression was used to estimate associations ...


Effects Of Conjugated Linoleic Acid (Cla) On Skeletal Muscle Metabolism, Yoo Kim Nov 2015

Effects Of Conjugated Linoleic Acid (Cla) On Skeletal Muscle Metabolism, Yoo Kim

Doctoral Dissertations

Although it is well known that increased physical activity can help reduce incidences of obesity, physical activity can be influenced by complex issues, making it difficult to use universal means to control obesity. Recent discoveries of the effects of exercise at the cellular level opened up the unique opportunity to develop compounds with ‘exercise-like’ effects. In fact, CLA has been shown to promote voluntary activity and endurance capacity in mice. Thus, the purpose of these studies is to determine the mechanisms of conjugated linoleic acid on muscle metabolism via the modulation of biochemical events including mitochondrial biogenesis and the alternation ...


Metformin And/Or Exercise Training Affect Metabolic Health In Men And Women With Prediabetes, Steven K. Malin May 2011

Metformin And/Or Exercise Training Affect Metabolic Health In Men And Women With Prediabetes, Steven K. Malin

Open Access Dissertations

Prediabetes is defined by elevated blood glucose concentrations not high enough to meet criteria for type 2 diabetes. Exercise or metformin, a common “anti-diabetes” medication, may attenuate the progression from prediabetes to type 2 diabetes by improving insulin sensitivity and cardio-metabolic health. Because each treatment has its primary action in different tissues, combining exercise (muscle) with metformin (liver) may further enhance insulin sensitivity and cardio-metabolic health. Purpose: To determine the efficacy of combining exercise training with metformin on insulin sensitivity and cardio-metabolic health in men and women with prediabetes. We hypothesized that the combined treatment would improve insulin sensitivity and ...
