Toxoplasmosis Complications And Novel Therapeutic Synergism Combination Of Diclazuril Plus Atovaquone, Helieh S. Oz
Toxoplasmosis Complications And Novel Therapeutic Synergism Combination Of Diclazuril Plus Atovaquone, Helieh S. Oz
Internal Medicine Faculty Publications
Toxoplasmosis is a major cause of foodborne disease, congenital complication, and morbidity. There is an urgent need for safe and effective therapies to encounter congenital and persisting toxoplasmosis. The hypothesis was: combination diclazuril plus atovaquone to exert a novel therapeutic synergy to prevent toxoplasmosis syndromes.
Methods: Pregnant dams were treated with diclazuril and atovaquone monotherapy or combination therapy and infected i.p with Toxoplasma tachyzoites.
RESULTS: Infected dams developed severe toxoplasmosis associated syndrome with increases in the abdominal adiposity surrounding uteri, gansterointestinal and other internal organs and excessive weight gain. Numerous organisms along with infiltration of inflammatory cells were detected …

BACKGROUND: Chronic hypersecretion of the pancreatic hormone amylin is common in humans with obesity or prediabetic insulin resistance and induces amylin aggregation and proteotoxicity in the pancreas. We recently showed that hyperamylinemia also affects the cardiovascular system. Here, we investigated whether amylin aggregates interact directly with cardiac myocytes and whether controlling hyperamylinemia protects the heart.
METHODS AND RESULTS: By Western blot, we found abundant amylin aggregates in lysates of cardiac myocytes from obese patients, but not in controls. Aggregated amylin was elevated in failing hearts, suggesting a role in myocyte injury. Using rats overexpressing human amylin in the pancreas (HIP …
Osteopontin: A Novel Regulator At The Cross Roads Of Inflammation, Obesity And Diabetes, Florian Kahles, Hannes M. Findeisen, Dennis Bruemmer
Osteopontin: A Novel Regulator At The Cross Roads Of Inflammation, Obesity And Diabetes, Florian Kahles, Hannes M. Findeisen, Dennis Bruemmer

Since its first description more than 20 years ago osteopontin has emerged as an active player in many physiological and pathological processes, including biomineralization, tissue remodeling and inflammation. As an extracellular matrix protein and proinflammatory cytokine osteopontin is thought to facilitate the recruitment of monocytes/macrophages and to mediate cytokine secretion in leukocytes. Modulation of immune cell response by osteopontin has been associated with various inflammatory diseases and may play a pivotal role in the development of adipose tissue inflammation and insulin resistance. Here we summarize recent findings on the role of osteopontin in metabolic disorders, particularly focusing on diabetes and …

Mid-life obesity and type 2 diabetes mellitus (T2DM) confer a modest, increased risk for Alzheimer's disease (AD), though the underlying mechanisms are unknown. We have created a novel mouse model that recapitulates features of T2DM and AD by crossing morbidly obese and diabetic db/db mice with APPΔNL/ΔNLx PS1P264L/P264L knock-in mice. These mice (db/AD) retain many features of the parental lines (e.g. extreme obesity, diabetes, and parenchymal deposition of β-amyloid (Aβ)). The combination of the two diseases led to additional pathologies-perhaps most striking of which was the presence of severe cerebrovascular pathology, including aneurysms and small …
Resveratrol And Cancer: Focus On In Vivo Evidence, Lindsay G. Carter, John A. D'Orazio, Kevin J. Pearson
Resveratrol And Cancer: Focus On In Vivo Evidence, Lindsay G. Carter, John A. D'Orazio, Kevin J. Pearson
Graduate Center for Nutritional Sciences Faculty Publications
Resveratrol is a naturally occurring polyphenol that provides a number of anti-aging health benefits including improved metabolism, cardioprotection, and cancer prevention. Much of the work on resveratrol and cancer comes from in vitro studies looking at resveratrol actions on cancer cells and pathways. There are, however, comparatively fewer studies that have investigated resveratrol treatment and cancer outcomes in vivo, perhaps limited by its poor bioavailability when taken orally. Although research in cell culture has shown promising and positive effects of resveratrol, evidence from rodents and humans is inconsistent. This review highlights the in vivo effects of resveratrol treatment on breast, …

Background
While farmers’ markets are a potential strategy to increase access to fruits and vegetables in rural areas, more information is needed regarding use of farmers’ markets among rural residents. Thus, this study’s purpose was to examine (1) socio-demographic characteristics of participants; (2) barriers and facilitators to farmers’ market shopping in southern rural communities; and (3) associations between farmers’ market use with fruit and vegetable consumption and body mass index (BMI).
Methods
Cross-sectional surveys were conducted with a purposive sample of farmers’ market customers and a representative sample of primary household food shoppers in eastern North Carolina (NC) and the …
The Role Of Angiotensinogen In Atherosclerosis And Obesity, Congqing Wu
The Role Of Angiotensinogen In Atherosclerosis And Obesity, Congqing Wu
Theses and Dissertations--Nutritional Sciences
Angiotensinogen is the only known precursor in the renin-angiotensin system, a hormonal system best known as an essential regulator of blood pressure and fluid homeostasis. Angiotensinogen is sequentially cleaved by renin and angiotensin- converting enzyme to generate angiotensin II. As the major effector peptide, angiotensin II mainly function through angiotensin type 1 receptor.
Angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and more recently renin inhibitors are widely known as the 3 classic renin-angiotensin system inhibitory drugs against hypertension and atherosclerosis. Here, we developed an array of regents to explore the effects of angiotensinogen inhibition. First, we demonstrated that genetic deficiency of …

Assessment Of Pediatric Primary Care Providers Behaviors And Procedures Regarding Pediatric Overweight And Obesity, Jessie N. Meiser
DNP Projects
CAPSTONE INTRODUCTION
Childhood overweight/obesity is a critical public health problem with devastating consequences. Many factors have combined to create the epidemic, and primary care providers can play an important role in addressing the problem by identifying overweight/obese children and encouraging them to engage in healthy behaviors. However, providers face a number of competing priorities making it difficult for them to provide these services effectively without outside support.
Obesity has reached an epidemic proportion in the nation’s youth. The Data Resource Center for Child and Adolescent Health (2011) found that 35.7% of children age 10 – 17 in Kentucky are overweight …

Impact Of Positive And Negative Health Behaviors On Female Mice And/Or Their Offspring, Kristen M. Platt
Theses and Dissertations--Pharmacology and Nutritional Sciences
Obesity is an ever-growing concern in the developed world that carries with it a plethora of health issues. For example, obesity increases an individual’s risk for Type 2 Diabetes and cardiovascular disease. Pregnancy is a vital time for a woman to maintain optimal health, both for her own benefit as well as that of her offspring, and yet almost half of women in the United States who are of age to bear children are overweight or obese. In mice, we found that offspring born to dams fed a high fat diet did not have impaired glucose tolerance, contrary to our …
