The Effect Of Body Mass Index On Graft Function And Kidney Transplant Outcomes, Morgan Galle

Theses & Dissertations

Background: When determining eligibility for kidney transplantation, body mass index (BMI) is often a debatable criterion for transplant due to the clinical indication, an elevated BMI has adverse effects on kidney transplant outcomes. There is a current gap in research on the effect BMI has on kidney transplant outcomes.

Purpose: The purpose of this study was to determine the role BMI plays in post-kidney transplant clinical outcomes including delayed graft function, new onset diabetes after transplant, wound complications, hospital length of stay, albumin, and readmissions to the hospital from initial hospitalization and at six months following kidney transplantation. The primary ...

Chronic Ethanol Exposure Enhances The Aggressiveness Of Breast Cancer: The Role Of P38Γ, Mei Xu, Siying Wang, Zhenhua Ren, Jacqueline A. Frank, Xiuwei H. Yang, Zhuo Zhang, Zun-Ji Ke, Xianglin Shi, Jia Luo

Pharmacology and Nutritional Sciences Faculty Publications

Both epidemiological and experimental studies suggest that ethanol may enhance aggressiveness of breast cancer. We have previously demonstrated that short term exposure to ethanol (12–48 hours) increased migration/invasion in breast cancer cells overexpressing ErbB2, but not in breast cancer cells with low expression of ErbB2, such as MCF7, BT20 and T47D breast cancer cells. In this study, we showed that chronic ethanol exposure transformed breast cancer cells that were not responsive to short term ethanol treatment to a more aggressive phenotype. Chronic ethanol exposure (10 days - 2 months) at 100 (22 mM) or 200 mg/dl (44 mM ...

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

Public Access Theses and Dissertations from the College of Education and Human Sciences

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 determined ...

Endoplasmic Reticulum Stress And Ethanol Neurotoxicity, Fanmuyi Yang, Jia Luo

Pharmacology and Nutritional Sciences Faculty Publications

Ethanol abuse affects virtually all organ systems and the central nervous system (CNS) is particularly vulnerable to excessive ethanol exposure. Ethanol exposure causes profound damages to both the adult and developing brain. Prenatal ethanol exposure induces fetal alcohol spectrum disorders (FASD) which is associated with mental retardation and other behavioral deficits. A number of potential mechanisms have been proposed for ethanol-induced brain damage; these include the promotion of neuroinflammation, interference with signaling by neurotrophic factors, induction of oxidative stress, modulation of retinoid acid signaling, and thiamine deficiency. The endoplasmic reticulum (ER) regulates posttranslational protein processing and transport. The accumulation of ...

Dashing Away Hypertension: Evaluating The Efficacy Of The Dietary Approaches To Stop Hypertension Diet In Controlling High Blood Pressure, Preeya Shah Phd, Kyle D. Maxwell, Joseph I. Shapiro Md

Biochemistry and Microbiology

The dietary approaches to stop hypertension (DASH) diet has been developed and popularized as a non-pharmaceutical intervention for high blood pressure reduction since 1995. However, to date, a comprehensive description of the biochemical rationale behind the diet’s principal guidelines has yet to be compiled. With rising interest for healthy and reliable life-style modifications to combat cardiovascular disease, this review aims to compile the most recent and relevant studies on this topic and make an informed assessment as to the efficacy of and underlying mechanisms operant in the DASH diet. Specifically, the merits of lowering dietary intake of sodium and ...

Alfáro, Li Chen, Dana L. Napier, Michael Lu, Jian-An Huang, Chunming Liu, Olivier Thibault, Rosalind Segal, Binhua P. Zhou, Natasha Kyprianou, Craig Horbinski, Xiuwei H. Yang

Pharmacology and Nutritional Sciences Faculty Publications

Glioblastoma, one of the most aggressive forms of brain cancer, is featured by high tumor cell motility and invasiveness, which not only fuel tumor infiltration, but also enable escape from surgical or other clinical interventions. Thus, better understanding of how these malignant traits are controlled will be key to the discovery of novel biomarkers and therapies against this deadly disease. Tetraspanin CD151 and its associated α3β1 integrin have been implicated in facilitating tumor progression across multiple cancer types. How these adhesion molecules are involved in the progression of glioblastoma, however, remains largely unclear. Here, we examined an in-house tissue microarray-based ...

Sarah L. Goff MD

BACKGROUND/OBJECTIVE: Diet books dominate the New York Times Advice Best Seller list and consumers cite such books as an important source of nutrition information. However, the scientific support for nutrition claims presented as fact (nutrition facts) in diet books is not known. DESIGN/MEASUREMENTS: We assessed the quality of nutrition facts in the best-selling South Beach Diet using support in peer-reviewed literature as a measure of quality. We performed structured literature searches on nutrition facts located in the books' text, and then assigned each fact to 1 of 4 categories (1) fact supported, (2) fact not supported, (3) fact ...

Intracellular Na+ Concentration ([Na+]I) Is Elevated In Diabetic Hearts Due To Enhanced Na+–Glucose Cotransport, Rebekah Lambert, Sarah Srodulski, Xiaoli Peng, Kenneth B. Margulies, Florin Despa, Sanda Despa

Pharmacology and Nutritional Sciences Faculty Publications

BACKGROUND: Intracellular Na⁺ concentration ([Na⁺]i) regulates Ca²⁺ cycling, contractility, metabolism, and electrical stability of the heart. [Na⁺]i is elevated in heart failure, leading to arrhythmias and oxidative stress. We hypothesized that myocyte [Na⁺]i is also increased in type 2 diabetes (T2D) due to enhanced activity of the Na⁺-glucose cotransporter.

METHODS AND RESULTS: To test this hypothesis, we used myocardial tissue from humans with T2D and a rat model of late-onset T2D (HIP rat). Western blot analysis showed increased Na⁺-glucose cotransporter expression in failing hearts from T2D patients compared with nondiabetic persons (by 73±13 ...

Roles Of Serum Lycopene In The Prevalence And Mortality Of Metabolic Syndrome In The Adult Population, Guang-Ming Han

Theses & Dissertations

Metabolic syndrome (MetS) is a cluster of metabolic disorders, including increased fasting glucose, blood pressure, plasma triglyceride, reduced high-density lipoprotein cholesterol and abdominal obesity. It leads to an increased risk of cardiovascular disease and diabetes. The growing prevalence of MetS is strongly related to the increasing prevalence of overweight/obesity. As an antioxidant, lycopene can reduce the risk of MetS. However, it is unclear whether lycopene has similar effects among overweight/obese individuals and whether lycopene can reduce the risk of mortality among individuals with MetS. The purpose of this study was to explore the roles of lycopene in the ...

Angiotensin Ii Is Required To Induce Exaggerated Salt Sensitivity In Dahl Rats Exposed To Maternal Separation, Analia S. Loria, David M. Pollock, Jennifer S. Pollock

Pharmacology and Nutritional Sciences Faculty Publications

We previously reported that maternal separation, rat model of early life stress, enhances pressor responses to acute and chronic stressors. The aims of this study were to determine whether Dahl salt-sensitive (DS) rats subjected to maternal separation (MatSep-DS) as compared to normally reared DS (Ctl-DS) rats show exaggerated blood pressure responses to acute behavioral stressors, such as restraint stress or air jet stress (AJS), or, hypertensive stimuli including chronic high-salt diet (4% NaCl) and angiotensin II (AngII) infusion (200 ng/Kg/min) during 1 week. MatSep was performed in male DS rats for 3 h/day from postnatal days 2-14 ...

Use Of Immunotherapy In The Treatment Of Peanut Allergies In The Pediatric Population, Bethany Rauscher

Senior Honors Theses

Peanut allergies are a serious issue that must be monitored and treated effectively to avoid severe adverse effects and death. In the last decade, their incidence has increased significantly, due to indeterminate factors. Because people typically do not outgrow peanut allergies and the effects of exposure can be life-threatening, it is important that a cure or management method is developed and refined. Recent research regarding treatment for peanut allergies has focused on the use of immunotherapy, a process aimed at desensitizing children's immune systems so that they do not reject foods that contain peanuts. Some studies utilizing immunotherapy have ...

The Cognitive Effects Of Chronic Malnutrition And Environment On Working Memory And Executive Function In Children, Kristiana E. Morgan

Independent Study Project (ISP) Collection

Chronic malnutrition, or stunting, occurs frequently in many developing countries such as Uganda. Stunting hinders physical growth and has been associated with delayed cognitive development, especially in young children. This study examined the effect of stunted growth on the function of cognitive processes involving the working memory and executive functions using neuropsychological assessments. Additionally, this study compared cognitive performances among rural and urban populations to analyze the environmental background differences which may affect cognition.

Population samples of fifteen five year old children classified as rural adequately nourished, rural stunted and urban adequately nourished were examined. Tests for working memory and ...

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 ...

Thrombospondin1 Deficiency Attenuates Obesity-Associated Microvascular Complications In Apoe-/- Mice, Hasiyeti Maimaitiyiming, Kate Clemons, Qi Zhou, Heather Norman, Shuxia Wang

Pharmacology and Nutritional Sciences Faculty Publications

Obesity is associated with insulin resistance and the increased development of vascular complications. Previously, we have demonstrated that thrombospondin1 (TSP1) regulates macrophage function and contributes to obesity associated inflammation and insulin resistance. However, the role of TSP1 in the development of obesity associated vascular complications is not clear. Therefore, in the current study, we investigated whether TSP1 deficiency protects mice from obesity associated micro as well as macro-vascular complications in ApoE-/- mice. In this study, male ApoE-/- mice and ApoE-/-TSP1-/- mice were fed with a low-fat (LF) or a high-fat (HF) diet for 16 weeks. We found that body ...

Cd47 Deficiency Protects Mice From Diet-Induced Obesity And Improves Whole Body Glucose Tolerance And Insulin Sensitivity, Hasiyeti Maimaitiyiming, Heather Norman, Qi Zhou, Shuxia Wang

Pharmacology and Nutritional Sciences Faculty Publications

CD47 is a transmembrane protein with several functions including self-recognition, immune cell communication, and cell signaling. Although it has been extensively studied in cancer and ischemia, CD47 function in obesity has never been explored. In this study, we utilized CD47 deficient mice in a high-fat diet induced obesity model to study for the first time whether CD47 plays a role in the development of obesity and metabolic complications. Male CD47 deficient and wild type (WT) control mice were fed with either low fat (LF) or high fat (HF) diets for 16 weeks. Interestingly, we found that CD47 deficient mice were ...

Pharmacology and Nutritional Sciences Faculty Publications

BACKGROUND: Hepatocellular carcinoma (HCC), the most common form of primary liver cancer, is the third leading cause of cancer-related death in human. Alcohol is a known risk factor for HCC. However it is still unclear whether and how alcohol enhances the progression and metastasis of existing HCC.

METHODS AND RESULTS: We first retrospectively investigated 52 HCC patients (24 alcohol-drinkers and 28 non-drinkers), and found a positive correlation between alcohol consumption and advanced Tumor-Node-Metastasis (TNM) stages, higher vessel invasion and poorer prognosis. In vitro and in vivo experiments further indicated that alcohol promoted the progression and migration/invasion of HCC. Specifically ...
