Inactivating mutations in the copper transporter Atp7b result in Wilson’s disease. The Atp7b−/− mouse develops hallmarks of Wilson’s disease. The activity of several nuclear receptors decreased in Atp7b−/− mice, and nuclear receptors are critical for maintaining metabolic homeostasis. Therefore, we anticipated that Atp7b−/− mice would exhibit altered progression of diet-induced obesity, fatty liver, and insulin resistance. Following 10 wk on a chow or Western-type diet (40% kcal fat), parameters of glucose and lipid homeostasis were measured. Hepatic metabolites were measured by liquid chromatography–mass spectrometry and correlated with transcriptomic data. Atp7b−/− mice fed a chow diet presented …

The Relationship Between Community Health Worker Supply And The Rate Of Preventable Hospitalizations Of Rural Latinos With Diabetes, Danielle O. Mapp

Honors Undergraduate Theses

The ever-increasing prevalence of diabetes mellitus and its associated healthcare costs in the United States has led to our healthcare system's need for cost-effective health resources and chronic disease management. The interventions of Community Health Workers (CHWs) can cost-effectively improve population health and prevent the unnecessary utilization of some medical services especially in rural, low-income, minority populations, where there is often limited access to healthcare. The purpose of this study is to investigate the relationship between the number of total CHWs in rural counties and the mean diabetes-related preventable hospitalization rates in Latino patients diagnosed with diabetes in those rural …

Thermal Analysis Of Infrared Irradiation-Assisted Nanosecond-Pulsed Tumor Ablation, James Hornef, Chelsea M. Edelblute, Karl H. Schoenbach, Richard Heller, Siqi Guo, Chunqi Jiang

Bioelectrics Publications

Nanosecond Pulsed Electric Fields (nsPEF) have the potential to treat a variety of cancer types including melanoma, pancreatic and lung squamous cancers. Recent studies show that nsPEF-based cancer therapy may be improved further with the assistance of moderate heating of the target. A feedbacklooped heating system, utilizing a 980-nm fiber optic laser, was integrated into nsPEF electrodes for tumor ablation. The laser beam profile was determined to be Gaussian using a knife-edge technique. Thermal properties of the biological target were evaluated based on the treatment area, penetration depth and thermal distribution due to laser irradiation with or without nsPEF. Synergistic …

Scholarship in Medicine - All Papers

Acute myocardial infarction and type two diabetes are within the top seven causes of death in the United States and their impact on society is costly. Although there are many studies conducted about these diseases, some of the research is aged and requires more recent datasets. The objective of this research is to revel trends in these diseases, as well as in their comorbidity, relating to age, gender, and race. To conduct this research, data has been collected from the CDC Wonder dataset using their comorbidity database. This comorbidity data uses USA death certificates from 1999-2017 to retrieve the medical …

Contaminants Of Emerging Concern: Reconsidering Our Paradigm Of Water Pollution, Jonathan Gunasti

Pomona Senior Theses

In this senior thesis, I explore contaminants of emerging concern (CECs) and endocrine disrupting compounds (EDCs) and discuss the ways in which these novel contaminants defy traditional notions of pollution. I discuss the history and “emergence” of CECs and EDCs in scientific and public spheres and outline ongoing challenges to recognizing, prioritizing, and understanding the action of these contaminants. I position EDCs within the framework of environmental injustice and health disparities and suggest that these compounds could reinforce multigenerational health inequities. Finally, I perform a pilot analysis of the EDC bisphenol A (BPA) in Mt. Baldy Creek, the Los Angeles …

Low Carbohydrate Ketogenic Diet Versus Aerobic Physical Activity In The Management And Treatment Of Type 2 Diabetes: A Review Paper, Nicole Weis

Capstone Showcase

Introduction: In recent decades, the number of people affected by type 2 diabetes mellitus has been a topic of interest. The wide reaching impact on both, individual and societal, healthcare costs and quality measures, begs for attention and interventions. Lifestyle modifications, such as: weight management or loss, increasing physical activity, and making healthier dietary choices, are the first line intervention. However, there are not studies that directly compare the role of a single dietary approach to a form of physical activity. Rather, different diets go head to head as well as aerobic versus resistance training. Therefore, in an attempt to …

Sirt3 Promotes Lipophagy And Chaperon-Mediated Autophagy To Protect Hepatocytes Against Lipotoxicity, Tian Zhang, Jingxin Liu, Shengnan Shen, Qiang Tong, Xiaojun Ma, Ligen Lin

Faculty, Staff and Students Publications

Lipophagy is a lysosomal lipolytic pathway that complements the actions of cytosolic neutral lipases. Chaperon-mediated autophagy (CMA) triggers lipid droplets (LDs) breakdown, to initiate lipolysis via either cytosolic lipases or macroautophagy. SIRT3, a mitochondrial NAD+-dependent deacetylase, regulates the acetylation status and activity of many substrates involving in energy metabolism. However, the role of SIRT3 in regulating lipophagy is controversial. The current study showed that SIRT3 expression was decreased and the macroautophagy flux was blocked in the primary hepatocytes from high-fat diet fed mice and P/O (palmitic acid and oleic acid mixture) treated AML12 mouse hepatocytes, compared with the corresponding controls. …

Aromatase Inhibitors Plus Weight Loss Improves The Hormonal Profile Of Obese Hypogonadal Men Without Causing Major Side Effects, Georgia Colleluori, Rui Chen, Christie G Turin, Francesca Vigevano, Clifford Qualls, Biju Johnson, Sanjay Mediwala, Dennis T Villareal, Reina Armamento-Villareal

Faculty, Staff and Students Publications

Objective: In obese men, the increased expression of the aromatase enzyme in adipose tissue leads to high conversion of androgens to estrogens contributing to hypogonadotropic hypogonadism (HHG). Our objective is to evaluate efficacy and safety of weight loss (WL) plus aromatase inhibitor (AI) therapy in severely obese men with HHG. We hypothesize that AI+WL will be more effective as compared to WL alone in improving the hormonal profile, thus muscle strength and symptoms of HHG (primary outcomes), with no significant adverse effects on lean mass, metabolic profile, and bone mineral density (secondary outcomes).

Design: Randomized double-blind placebo-controlled pilot trial.

Methods: …

Hypogonadism, Type-2 Diabetes Mellitus, And Bone Health: A Narrative Review, Vittoria Russo, Rui Chen, Reina Armamento-Villareal

Faculty, Staff and Students Publications

One of the complications from chronic hyperglycemia and insulin resistance due to type 2 diabetes mellitus (T2DM) on the hypothalamic-pituitary-gonadal axis in men is the high prevalence of hypogonadotropic hypogonadism (HH). Both T2DM and hypogonadism are associated with impaired bone health and increased fracture risk but whether the combination results in even worse bone disease than either one alone is not well-studied. It is possible that having both conditions predisposes men to an even greater risk for fracture than either one alone. Given the common occurrence of HH or hypogonadism in general in T2DM, a significant number of men could …

Targeted Inhibition Of Histone Deacetyltransferases For Pancreatic Cancer Therapy, Richard Laschanzky

Theses & Dissertations

Pancreatic ductal adenocarcinoma (PDAC) is a deadly disease with a dismal five-year survival rate of less than 10%. One major obstacle in PDAC treatment is acquired drug resistance. Pan-histone deacetylase inhibitors (pan-HDACi) are a relatively new class of anti-cancer drugs, with demonstrated ability to overcome drug resistance and re-sensitize PDAC tumors to Gemcitabine (Gem). These agents target HDACs, a family of 18 enzymes (divided into four classes, I-IV) that catalyze the deacetylation of histones and other cellular proteins and have multiple effects on cell growth, differentiation, survival, and tumorigenesis. Although pan-HDACi have shown significant efficacy in preclinical analysis, and some …

Fda Approves New Inhaled Insulin: Afrezza® (Technosphere® Insulin), Benjamin Finley, Christina Ciccone, Kimberly Loughlin, Michelle Musser

Pharmacy and Wellness Review

Diabetes is an endocrine disease caused by deficiency or malfunction of insulin that results in high blood glucose levels and places patients at higher risk for a number of complications. This chronic disease is difficult to manage and affects millions of people in the United States, costing the health care system billions of dollars a year. Of a variety of antidiabetic agents used to control blood glucose, insulin is perhaps the most effective, but until recently it was only available in injectable form. As of June 27, 2014, a new inhaled insulin called Afrezza® (Technosphere® insulin) was approved by the …

Polycystic Ovarian Syndrome And Hyperinsulinemia: Overview And Treatment, Amanda M. Meyer, Lauren D. Bajbus, Sarah E. Drake, Kristen M. Quertinmont, Ashley Overy, Anne Gentry

Pharmacy and Wellness Review

Polycystic ovary syndrome is a prevalent issue in women's health that is associated with hyperinsulinemia and insulin resistance and can lead to long-term health problems. The most highly recommended treatments are diet and lifestyle changes. If these changes alone are not enough, pharmacologic treatments may be employed which include metformin, spironolactone or thiazolidinediones, although more research is needed to fully realize their role. The role of the pharmacist in this disease state includes counseling patients on healthy lifestyle changes, consulting with the physician about prescribing the best medication for each patient, and monitoring therapy adherence in the patient.

Using The Adam Questionnaire In Primary Care To Identify Hypoandrogenism In Males Aged 40 Years Or Older, Jeremy Burns

Doctor of Nursing Practice

Testosterone replacement therapy (TRT) has been shown to improve the symptoms of metabolic syndrome by reducing Hemoglobin A1C, belly fat, cholesterol, and blood pressure (Cunningham, 2015). The ultimate goal for testosterone-deficient patients is to have an improved quality of life by starting TRT. This quality improvement project was conducted at a small primary care clinic in South Texas. The project was started by screening 84 male patients ≥ 40 years of age using the Androgen Deficiency in Aging Males (ADAM) questionnaire. The ADAM questionnaire was considered positive for anyone who answered “yes” to 3 or more questions or “yes” to …

Evidence-Based Foot Care For Persons With Type 2 Diabetes, Nicole Gutierrez

Doctor of Nursing Practice

Unmanaged Type 2 diabetes leads to macrovascular changes that affect the lower extremities, thereby damaging the sensory nerve fibers and leading to diabetic peripheral neuropathy. These patients may not be able to feel pain, heat, or cold in their lower extremities and often describe feelings of numbness and tingling. This sensory deficit may lead to the development of diabetic foot ulcers which often result in amputation. These preventable foot complications may be identified promptly with adequate diabetic foot exams. Comprehensive diabetic foot examinations reduce the occurrences of foot complications associated with uncontrolled glucose management and improves health outcomes for patients …

Prevention And Treatment Of Glucocorticoid-Induced Osteoporosis, Mackenzie Devine, Anh Dao Le, Julie Puvogel, Victoria Cho, Michelle Musser

Pharmacy and Wellness Review

Osteoporosis is a disease state resulting in decreased bone mineral density (BMD) and increased risk of fracture, specifically of the vertebrae, spine and hip. Risk factors and high risk populations for developing osteoporosis include low BMD, long-term glucocorticoid therapy, genetics, diet, postmenopausal women and patients with inflammatory or chronic disease states. A variety of signaling pathways involving hormones, cytokines and other signaling molecules are involved in bone formation and are affected by long-term glucocorticoid therapy, leading to the development of glucocorticoid-induced osteoporosis (GIO).

There are a variety of drugs that work efficaciously to prevent and treat GIO. Alendronate is a …

Potential Use Of Dopamine And Dopamine Agonists As Angiogenesis Inhibitors In The Treatment Of Cancer, Benjamin Finley, Katherine Liu, Daniel Powell, Jamie Kellner, David H. Kinder

Pharmacy and Wellness Review

In recent years, there have been numerous developments in monoclonal antibodies used as anticancer drugs with a focus on reducing the ability of cancers to metastasize and produce new vasculature. These agents are called angiogenesis inhibitors and although these agents have been proven effective in treating certain types of cancers, production and administration of monoclonal antibodies comes at a steep cost with a severe side effect profile. Under normal physiologic conditions, angiogenesis is an important mechanism to create new blood vessels from preexisting vessels, usually occurring in adults. Tumor cells can hijack the angiogenesis pathway to produce new distant tumors …
