Rnai-Mediated Control Of Aflatoxins In Peanut: Method To Analyze Mycotoxin Production And Transgene Expression In The Peanut/Aspergillus Pathosystem, Renee S. Arias, Phat M. Dang, Victor S. Sobolev

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The Food and Agriculture Organization of the United Nations estimates that 25% of the food crops in the world are contaminated with aflatoxins. That represents 100 million tons of food being destroyed or diverted to non-human consumption each year. Aflatoxins are powerful carcinogens normally accumulated by the fungi Aspergillus flavus and A. parasiticus in cereals, nuts, root crops and other agricultural products. Silencing of five aflatoxin-synthesis genes by RNA interference (RNAi) in peanut plants was used to control aflatoxin accumulation following inoculation with A. flavus. Previously, no method existed to analyze the effectiveness of RNAi in individual peanut transgenic events, …

Brown And Beige Adipocytes: Effects Of Inflammation And Nutritional Intervention, Jiyoung Bae

Doctoral Dissertations

Recent findings of brown adipocytes and brown-like or beige adipocytes, capable of dissipating energy as heat, in adult humans have promised new hope for obesity treatment and prevention. Understanding of the regulation of brown and beige adipocytes will provide novel strategies to reach the goal. Pattern recognition receptors (PRR) are responsible for inflammation in adipose tissue, which leads to adipose dysfunction and obesity associated chronic diseases. It has been shown that PRR activation induces inflammation, leading to insulin resistance in white adipocytes and white adipose tissue (WAT). However, the roles of PRR activation in brown adipocytes and brown adipose tissue …

Mechanisms By Which Dietary Ellagic Acid Attenuates Obesity And Obesity-Mediated Metabolic Complications, Inhae Kang

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Ellagic acid (EA) is a polyphenol found in various fruits and plants, such as berries, pomegranates, muscadine grapes, nuts and bark of oak tree. EA has been known to exhibit anti-inflammatory and anti-proliferative effects in various types of cancer. However, little is known about the effects of EA on obesity. Herein, 1) the lipid-lowering role of EA was identified in primary human adipose stem cells (hASCs) and human hepatoma Huh7 cells; 2) the molecular mechanisms by which EA attenuates adipogenesis by epigenetic modification were identified; 3) the effects of EA on high fat and high sucrose-mediated obesity was …

Should Primary Care Physicians Address Sleep To Improve Weight Loss In Obese Patients? A Clin-Iq, Kjersti E. Knox

Journal of Patient-Centered Research and Reviews

Obesity is a commonly encountered problem in the primary care setting. Simultaneously, sleep is seen to hold an increasingly important role in many components of health and wellness. A review of the literature was performed to determine if improving sleep positively impacts weight loss in obese adults. The evidence reviewed suggests that improving patients’ sleep may initially improve patient weight loss; however, current studies do not show a sustained statistically significant impact. Until higher powered and higher quality studies are completed, there are no clear evidence-based guidelines for primary care physicians to follow regarding sleep and obesity.

A cross-sectional study was conducted to assess the contributions of diabetes status to dental service use, relative to the contributions of Andersen and Newman Framework of Health Services Utilization dimensions (predisposing, enabling, and illness variables) in predicting dental service utilization during the past year using a nationally representative sample from a 2001-2002 National …

An Investigation Of The Integration Of Education And Mental Health Treatment Into The Care Of Diabetes In Syrian Refugee Women, Miller Richmond

Independent Study Project (ISP) Collection

Due to the fact that Syrian refugees’ situation subjects them to unusual, acute stresses, health professionals must proactively screen them for mental disorders. Many studies show that the correlation between diabetes and mental illness is very strong, thus treatment of diabetic refugees should consider the mental health of the patient in order to ensure successful management of the disease. Additionally, health education should be emphasized as both a route to successful disease management and a route to overall health literacy that can empower the refugee to make important and efficient decisions about accessing health services. This study examined the integration …

Non-Invasive Determination Of Pre-Clinical Markers Of Cardiovascular Diseases In Low Birth Weight And Maternal Western Diet Guinea Pig Offspring Exposed To A Postnatal Western Diet, Jacky Chiu

Electronic Thesis and Dissertation Repository

Low birth weight (LBW), and maternal Western Diet (WD) consumption have both been independently implicated to increase the risk of developing cardiovascular diseases (CVDs) in later life. These fetal programmed risks are also believed to exacerbate the effects of a postnatal WD pattern. Therefore, resulting in the development of pre-clinical markers of CVDs, such as insulin resistance (IR), coronary circulation disruptions. This thesis aimed to elucidate the roles of sub-optimal in utero growth through placental insufficiency, or chronic maternal WD consumption, and postnatal WD consumption on the long-term programming of CVDs in a guinea pig model. Early pre-clinical markers of …

Relationships Between Age And White Matter Integrity In Children With Phenylketonuria, Erika M. Wesonga

Arts & Sciences Electronic Theses and Dissertations

Objective: Phenylketonuria (PKU) is a hereditary metabolic disorder associated with cognitive compromise. Diffusion tensor imaging (DTI) has allowed detection of poorer microstructural white matter integrity in children with PKU, with decreased mean diffusivity (MD) in comparison with healthy children. However, very little research has been conducted to examine the trajectory of white matter development in this population. The present study investigated potential differences in the developmental trajectory of MD between children with early- and continuously-treated PKU and healthy children across a range of brain regions.

Methods: Children with PKU (n = 31, mean age = 12.2 years) were …

Obesity Early In Adulthood Increases Risk But Does Not Affect Outcomes Of Hepatocellular Carcinoma, Manal M. Hassan, Reham Abdel-Wahab, Ahmed Kaseb, Ahmed Shalaby, Alexandria Phan, Hashem El-Serag, Ernest Hawk, Jeff Morris, Kanwal Pratap Singh Raghav, Ju-Seog Lee, Jean-Nicolas Vauthey, Gehan Bortus, Harrys Torres, Christopher Amos, Robert Wolff, Donghui Li

Dartmouth Scholarship

Despite the significant association between obesity and several cancers, it has been difficult to establish an association between obesity and hepatocellular carcinoma (HCC). Patients with HCC often have ascites, making it a challenge to accurately determine body mass index (BMI), and many factors contribute to the development of HCC. We performed a case–control study to investigate whether obesity early in adulthood affects risk, age of onset, or outcomes of patients with HCC.

Raising Awareness: Polycystic Kidney Disease, Dana Dendinger

Nursing Student Class Projects (Formerly MSN)

A young male patient was recently admitted to the intensive care unit at a local hospital with hypertensive urgency and acute renal failure of unknown etiology. A renal ultrasound showed polycystic kidneys and upon further investigation, it was discovered that the patient’s mother passed away last year from end stage renal failure related to polycystic kidney disease (PKD). The aforementioned case and the recent study into inherited disorders are what prompted further investigation into PKD. Liebau and Serra (2013) explain that “inherited cystic kidney diseases, autosomal dominant polycystic kidney disease (ADPKD) and autosomal recessive polycystic kidney disease (ARPKD), are the …

Molecular Mechanisms Linking Amino Acid (Leucine) Deprivation To Igfbp-1 Hyperphosphorylation In Fetal Growth Restriction, Niyati M. Malkani

Electronic Thesis and Dissertation Repository

In this study, we explore the molecular mechanisms linking amino acid (leucine) deprivation to IGFBP-1 hyperphosphorylation in vitro. During pregnancy, a maladaptive fetal response to in utero amino acid deprivation leads to Fetal Growth Restriction (FGR). FGR infants display elevated phosphorylated IGFBP-1, which is associated with decreased IGF-I bioavailability. Leucine deprivation inhibits mechanistic target of rapamycin (mTOR) signaling and stimulates the amino acid response (AAR). Using HepG2 cells, a model for fetal hepatocytes, we demonstrate that in leucine deprivation, the AAR modulates total and phosphorylated IGFBP-1 while mTOR mediates total IGFBP-1 secretion only. We also reveal that protein kinases …

A Translational Study Determining The Impact Of Timing And Duration Of Aerobic Walking On Metabolic Control And Personal Preferences Among Adults Recently Diagnosed With Type 2 Diabetes, Cory Cox

Graduate Theses

Type 2 diabetes (T2D) is a potentially life threatening metabolic disease characterized by insulin resistance and inability to metabolize glucose (Meneilly & Elliott 1999). According to the American Diabetes Association (ADA, 2013), diabetes played a contributing role in 231,404 deaths in 2007 alone. Because of this, researchers strive to develop the best methods of managing diabetes. Physical activity has been shown to improve glucose control by reducing insulin resistance and reducing body fat (Bacchi et al., 2012). Recent data from DiPietro et al. (2013) indicated that multiple bouts of exercise may be favorable over one continuous bout in managing blood …

Evaluation Of Bde-47 And -99 Lipid Modulating Effects In Hepg2 Human Carcinoma Cells, Eileen A. Holovac

Senior Honors Projects

Non-alcoholic fatty liver disease (NAFLD) is becoming a significantly more common problem in today’s society, affecting up to 25% of people in the United States as reported by the American Liver Foundation. According to the American Association of the Study of Liver Diseases, NAFLD is the buildup of fat in the liver that is not caused by secondary factors such as alcohol consumption, hereditary disorders, or the use of steatogenic medication such as amioderone. A liver is considered fatty when 5-10% of the liver’s weight is fat. The progression of NAFLD can lead to cirrhosis, liver cancer, or liver failure. …

Diabetic Bone Marrow & Stem Cell Dysfunction, Meghan A. Piccinin

Electronic Thesis and Dissertation Repository

ii Abstract Abstract Defects in the proliferation, differentiation, and activity of bone marrow (BM)-derived vasculogenic/vascular stem cells (VSCs) have been observed in diabetes and contribute to the development of vascular complications. Diabetes leads to enhanced bone marrow adipogenesis, altering the composition of the BM stem cell (SC) niche and potentially disrupting the normal functioning of resident VSCs. Here, I establish that adipocytes have a negative influence on SC survival in culture. I also show that adipocytes and osteoblasts are responsible for the creation of distinct extracellular microenvironments, with unique expression patterns of several pro- and anti-angiogenic factors with known effects …

Nonenzymatic Glycosylation Of Erythrocyte Membrane Proteins. Relevance To Diabetes, J A. Miller, Ellen M. Gravallese, H F. Bunn

Ellen M. Gravallese

Nonenzymatic glycosylation of proteins of the erythrocyte membrane was determined by incubating erythrocyte ghosts with [3H]borohydride. The incorporation of tritium into protein provides a reliable assay of ketoamine linkages. The membrane proteins from 18 patients with diabetes incorporated twice as much radioactivity as membrane proteins from normal erythrocytes. After acid hydrolysis, amino acid analysis showed that the majority of radioactivity was localized to glucosyllysine. Autoradiograms showed that all of the major proteins of the erythrocyte membrane, separated by electrophoresis on sodium dodecyl sulfate gels, contained ketoamine linkages. No protein bands in either normal or diabetic erythrocytes showed significant preferential labeling. …

The Effect Of Aerobic Exercise Training On Hepatic Glycogen Metabolism In Type 1 Diabetic Rats, Michael Murray

Electronic Thesis and Dissertation Repository

The purpose of this investigation was to determine if ten weeks of aerobic exercise training could increase hepatic glycogen storage in rats with Type 1 Diabetes Mellitus (T1DM) and whether elevated hepatic glycogen content is associated with alterations in glycogenic proteins and insulin signaling. Rats were divided into control-sedentary, control-exercised, T1DM-sedentary and T1DM-exercised groups. Animals from each group underwent a euglycemic-hyperinsulinemic clamp at the conclusion of the study. Exercise training consisted of treadmill running at 27m/min, 6% incline for 1hr, five days/week for ten weeks. T1DM rats had lower liver glycogen concentrations than control rats and glycogen was not increased …

Television Watching, Diet Quality, And Physical Activity And Diabetes Among Three Ethnicities In The United States, Fatma G. Huffman, Joan A. Vaccaro, Joel C. Exebio, Gustavo C. Zarini, Timothy Katz, Zisca Dixon

Joan A. Vaccaro

Diabetes is a world-wide epidemic associated with multiple environmental factors. Prolonged television viewing (TV) time has been related to increased risk of obesity and type 2 diabetes in several studies. TV viewing has been positively associated with cardiovascular disease risk factors, lower energy expenditure, over-eating high-calorie and high-fat foods. The objective of this study was to assess the associations of hours of TV viewing with dietary quality, obesity and physical activity for three ethnic minorities with and without type 2 diabetes. Diet quality and physical activity were inversely related to prolonged TV viewing. African Americans and participants with type 2 …

Monounsaturated Fatty Acid, Carbohydrate Intake, And Diabetes Status Are Associated With Arterial Pulse Pressure, Joan Vaccaro, Fatma G. Huffman

Joan A. Vaccaro

Background

Diabetes is a global epidemic. Cardiovascular disease (CVD) is one of the most prevalent consequences of diabetes. Nutrition is considered a modifiable risk factor for CVD, particularly for individuals with diabetes; albeit, there is little consensus on the role of carbohydrates, proteins and fats for arterial health for persons with or without diabetes. In this study, we examined the association of macronutrients with arterial pulse pressure (APP), a surrogate measure of arterial health by diabetes status and race.

Methods

Participants were 892 Mexican Americans (MA), 1059 Black, non-Hispanics (BNH) and 2473 White, non-Hispanics (WNH) with and without diabetes of …

Healthy Eating Index And Alternate Healthy Eating Index Among Haitian Americans And African Americans With And Without Type 2 Diabetes, Fatma G. Huffman, Mauricio De La Cera, Joan A. Vaccaro, Gustavo C. Zarini, Joel C. Exebio, Deva Gundupalli, Lamya Shaban

Joan A. Vaccaro

Ethnicities within Black populations have not been distinguished in most nutrition studies. We sought to examine dietary differences between African Americans (AA) and Haitian Americans (HA) with and without type 2 diabetes using the Healthy Eating Index, 2005 (HEI-05), and the Alternate Healthy Eating Index (AHEI). The design was cross-sectional (225 AA, 246 HA) and recruitment was by community outreach. The eating indices were calculated from data collected with the Harvard food-frequency questionnaire. African Americans had lower HEI-05 scores (−8.67, 13.1); , than HA. Haitian American females and AA males had higher AHEI than AA females and HA males, respectively, …

Medical Advice And Diabetes Self-Management Reported By Mexican-American, Black- And White-Non-Hispanic Adults Across The United States, Joan A. Vaccaro, Daniel J. Feaster, Sandra L. Lobar, Marianna K. Baum, Marcia Magnus, Fatma G. Huffman

Joan A. Vaccaro

Background

Diabetes has reached epidemic proportions in the United States, particularly among minorities, and if improperly managed can lead to medical complications and death. Healthcare providers play vital roles in communicating standards of care, which include guidance on diabetes self-management. The background of the client may play a role in the patient-provider communication process. The aim of this study was to determine the association between medical advice and diabetes self care management behaviors for a nationally representative sample of adults with diabetes. Moreover, we sought to establish whether or not race/ethnicity was a modifier for reported medical advice received and …
