The tuber was extracted with hexane, petroleum-ether, chloroform, methanol and water solvents. The seperation and detection of bioactive compounds were done using Thin Layer Chromatography (TLC) and Gas Chromatography Mass Spectrometry (GCMS) methods. The TLC results showed the presence of phenolic acids, flavonoids and terpenoids. While in GCMS has revealed the presence of hydrocarbon groups such as alkene, ester and ether, amino acid groups, dicarboxylic acid and cyclic aromatic compound. The total phenol content and total flavonoid content were highest in methanolic …

Metabolic-Sensing Of The Skeletal Muscle Clock Coordinates Fuel Oxidation, Hongshan Yin, Weini Li, Somik Chatterjee, Xuekai Xiong, Pradip Saha, Vijay Yechoor, Ke Ma

Faculty, Staff and Students Publications

Circadian clock confers temporal control in metabolism, with its disruption leading to the development of insulin resistance. Metabolic substrate utilization in skeletal muscle is coordinated with diurnal nutrient cycles. However, whether the molecular clock is involved in this coordination is largely unknown. Using a myocyte-selective genetic ablation mouse model of the essential clock activator Bmal1, here we identify muscle-intrinsic clock as a sensor of feeding cues to orchestrate skeletal muscle oxidation required for global nutrient flux. Bmal1 in skeletal muscle responds robustly to feeding in vivo and insulin induces its expression. Muscle Bmal1 deficiency impaired the transcriptional control of glucose …

Development Of Paper-Based Screen-Printed Carbon-Paste Electrode For Sensing Glucose For Diabetics, Yechan Hwang

19th Annual Celebration of Undergraduate Research and Creative Activity (2020)

In recent years there have been many interests in developing paper based electrodes.[1] The purpose of this project is to develop a working paper-based electrode that can detect glucose via an enzyme and redox mediator (Tris(5-amino-1, 10-phenanthroline) Iron(II)). In the process of developing a paper-based electrode, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were used as primary methods. The redox mediator was electropolymerized onto glassy carbon (GC) and carbon-paste electrodes (CPE) and their subsequent charge-transfer properties were characterized using CV and EIS. Cyclic voltammetry characterization studies of the electropolymerized films revealed excellent charge transfer properties with ΔEp ~0 mV. …

A Collaborative Approach To Incentivizing Healthy Food Choices Among Uncontrolled Diabetic Patients At A Local Federally Qualified Health Center To Improve Health Outcomes, Briauna J. Taylor

Doctoral Projects

Background: The rate of uncontrolled diabetes among patients at a local Federally Qualified Health Center (FQHC) is higher than the nation standard, a phenomenon believed to be caused by the effects of social determinants of health (SDOH). SDOH, specifically food insecurity, play a significant role in health outcomes of diabetic patients. Increasing access to healthy foods, thereby reducing food insecurity, has the potential to improve glycemic control and reduce diet related chronic disease.

Objectives: The project aims to determine if partnership with a membership based incentivized grocery store has the potential to positively impact health outcomes among vulnerable patients with …

Diabetes Debunked: What You Need To Know, Maggie Hutson

Honors Program: Senior Projects (Public)

The goal of this Honors creative project is to encourage health literacy in populations who are curious about Type 2 Diabetes or have Type 2 Diabetes. From personal experience, I have seen noncompliance in diabetics and wondered why since it is a serious, progressive disease. After researching, I found that some diabetics do not understand the scope of their disease, especially since many of the dangerous complications that arise from Type 2 Diabetes do not present until later in the disease when it is too late. For my senior project, I decided to write an educational paper as a supplement …

The Impact Of Diabetic Foot Ulcers And Unilateral Offloading Footwear On Gait In People With Diabetes, Erica Ling, Brian Lepow, He Zhou, Ana Enriquez, Ashley Mullen, Bijan Najafi

Faculty, Staff and Students Publications

BACKGROUND: Unilateral offloading footwear prescribed to patients with diabetic foot ulcers elevates one limb relative to the other, which may lead to limp and abnormal gait. This study investigated whether the unilateral foot ulcer and offloading combination negatively impacts gait function beyond diabetic peripheral neuropathy.

METHODS: Eighty-six participants were recruited in 3 groups: 12 with diabetic peripheral neuropathy and unilateral foot ulcers wearing offloading footwear (offloading group, age = 55.6 ± 9.5 years, BMI = 30.9 ± 4.5 kg/m

FINDINGS: The offloading group exhibited deteriorated gait function compared to the non-diabetic group (p < 0.005, Cohen's effect size d = 0.90-2.61). They also had decreased gait speed (p < 0.001, d = 1.79) and stride length (p < 0.001, d = 1.76), as well as increased gait cycle time (p < 0.001, d = 1.67) and limp (p < 0.050, d = 0.72-1.49) compared to the neuropathy group. The offloading group showed increased gait unsteadiness compared to the neuropathy group, but the difference did not reach statistical significance in our samples.

INTERPRETATION: This study demonstrated that while diabetic …

Faculty, Staff and Students Publications

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 …

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.

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 …
