The obesity epidemic is a ‘wicked’ problem with a complex web of determinants and outcomes. While generally higher for minoritized populations, prevalence rates manifest in surprising, nonlinear patterns. There is no consensus regarding treatment protocols or mitigation efforts, except that current efforts remain largely ineffective. Much research evidence that a profusion of determinants of health support obesity pathogenesis through various physiological processes and mechanisms, including the allostatic load, mitochondria functioning, the gut microbiome, and epigenetics. Intervening to support markers of the allostatic load (immunity, inflammation, and metabolic health) may provide a more effective treatment outcomes than traditional approaches, which tend …

Hif Expression In Clear-Cell Renal Cell Carcinoma (Ccrcc) Tumors Of Adults With And Without Obstructive Sleep Apnea (Osa), Olivia Heppell, Carlos Guerra Londono, Nilesh Gupta
Medical Student Research Symposium
Introduction: Upregulation of hypoxia-inducible factors (HIF) is an important pathological feature shared by clear cell renal cell carcinoma (ccRCC) and obstructive sleep apnea (OSA). However, it is unclear whether OSA alters the pathogenesis of ccRCC via HIF expression.
Methods: A retrospective cohort of adults undergoing nephrectomy for ccRCC was identified electronically (IRB#16040-1). The diagnosis of OSA was established with preoperative STOP-BANG scores or polysomnography. A consecutive sample of 20 individuals with and 20 without OSA was selected. Clinical characteristics and pathology results were reviewed. Resected tumor sections were immunohistochemically stained for HIF-1& HIF-2 at antibody dilutions of 1:150. Intensity and …

BACKGROUND: The circulating metabolome, reflecting underlying cellular processes and disease biology, has not been fully characterized in patients with idiopathic pulmonary fibrosis (IPF). We evaluated whether circulating levels of metabolites correlate with the presence of IPF, with the severity of IPF, or with the risk of clinically relevant outcomes among patients with IPF.
METHODS: We analyzed enrollment plasma samples from 300 patients with IPF in the IPF-PRO Registry and 100 individuals without known lung disease using a set of targeted metabolomics and clinical analyte modules. Linear regression was used to compare metabolite and clinical analyte levels between patients with IPF …

Reducing Food Scarcity: The Benefits Of Urban Farming, 2023 Brigham Young University
Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia
Journal of Nonprofit Innovation
Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

Purpose: To our knowledge, there are very few studies evaluating if the levels of folate modify the risk of cervical intraepithelial neoplasia grade 2 and higher (CIN2+ and CIN3+) associated with the levels of HPV genome methylation, two cofactors related to single carbon metabolism and independently associated with cervical cancer in previous studies. We conducted a case–control study nested in a three-arm randomized clinical pragmatic trial (ASCUS-COL trial) to evaluate the risk of CIN3+ associated with methylation levels according to serum folate concentrations. Methods: Cases (n = 155) were women with histologically confirmed CIN2+ (113 CIN2, 38 CIN3, and 4 …
Vitamin D Status Of Anabaptist Children In Southwestern Ontario, Canada, 2023 University of Guelph
Vitamin D Status Of Anabaptist Children In Southwestern Ontario, Canada, Janis A. Randall Simpson, Natalee Miller, Taylor Hartwig, Jane Leach, Melissa Purdy, Emily Roth, Victoria Mok Siue, Cynthia Soulliere, Jacqui Tam, Ann Watt
Journal of Amish and Plain Anabaptist Studies
The objective was to determine vitamin D status of Old Order Anabaptist children in rural Southwestern, Ontario, Canada, given concerns of community healthcare professionals. Fifty-two children (2.5 months - 6.5 years) (56% female) were recruited. Finger prick blood spot (BSp) samples were analyzed for 25-hydroxy (OH) vitamins D2 & D3 (BSp25(OH)D). Three-day food records were evaluated using Dietary Reference Intakes and Canada’s Food Guide (CFG) (Bush, et al. 2007). Compared to national Canadian data: mean BSp25(OH)D concentrations (78±31 nmol/L) were similar; a slightly smaller proportion (0% vs 2%) were at risk of deficiency (<30 nmol/L) or had inadequate status (4% vs 7%) (<40 nmol/L); and 10% vs 1% had BSp25(OH)D higher than 125 nmol/L. BSp25(OH)D was significantly associated (r2=0.358; p=0.001) with total vitamin D intake. From food alone, vitamin D intake was 68±39 IU/day, lower than the Recommended Dietary Allowance (RDA) of 600 IU/day, and intakes were all below the Estimated Average Requirement (EAR) of 400 IU. Even including supplemental vitamin D, 87% were below the EAR (total intake=213±194 IU/day). No children had vitamin D intakes greater than the Upper Limit. Servings of milk and alternates were 1.6±0.8/day (CFG=2/day). Unfortified farm milk was consumed by 88% of children and 89% received a vitamin D supplement. Results were comparable to recent Canadian data suggesting that most children have adequate vitamin D status. Nevertheless, these findings support the need to encourage appropriate vitamin D intake (from food and supplements) to achieve the RDA for Old Order Anabaptist children in these communities.

A Literature Review On Thermogenesis As A Prospective Obesity Treatment, 2023 Liberty University
A Literature Review On Thermogenesis As A Prospective Obesity Treatment, Kellyn Sheppard
Senior Honors Theses
The disease of obesity has quickly escalated from an epidemic to a worldwide pandemic in the last few decades, and viable treatment methods are being investigated with urgency. One such treatment method is increased induction of the thermogenesis pathway that is active in brown adipose tissue. This pathway is typically activated in mammals when they are exposed to cold temperatures for extended periods of time but can also be induced exogenously. Thermogenesis is a metabolically inefficient process that occurs in the mitochondria of a cell, meaning it uses substrate energy without generating ATP. The inefficiency of this process allows excess …
Effects Of Dimerization On The Deacylase Activities Of Human Sirt2., 2023 Rowan University
Effects Of Dimerization On The Deacylase Activities Of Human Sirt2., Jie Yang, Nathan I Nicely, Brian P Weiser
Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship
Human sirtuin isoform 2 (SIRT2) is an NAD+-dependent enzyme that functions as a lysine deacetylase and defatty-acylase. Here, we report that SIRT2 readily dimerizes in solution and in cells and that dimerization affects its ability to remove different acyl modifications from substrates. Dimerization of recombinant SIRT2 was revealed with analytical size exclusion chromatography and chemical cross-linking. Dimerized SIRT2 dissociates into monomers upon binding long fatty acylated substrates (decanoyl-, dodecanoyl-, and myristoyl-lysine). However, we did not observe dissociation of dimeric SIRT2 in the presence of acetyl-lysine. Analysis of X-ray crystal structures led us to discover a SIRT2 double mutant (Q142A/E340A) that …
Green Tea Supplementation: An Effective Lifestyle Modification For Cholesterol Management, 2023 University of Texas at Tyler
Green Tea Supplementation: An Effective Lifestyle Modification For Cholesterol Management, Samuel J. Nemati
MSN Capstone Projects
Hypercholesterolemia is an insidious disease and the leading factor to the deadliest killer in the United States – cardiovascular disease (Centers for Disease Control and Prevention, 2023a). Over 85 million American adults suffer from elevated cholesterol, and treatment can prove challenging and may require multiple modalities outside just pharmaceutical intervention – such as dietary and other lifestyle changes (Centers for Disease Control and Prevention, 2023b; Goldman, 2023). Green tea – among the most common teas consumed worldwide – exerts a uniquely antihyperlipidemic and cardioprotective effect that suggests its consideration as a potentially-viable nonpharmacological option for hypercholesterolemia (Harvard Health Publishing, 2012; …
Ethanol Dysregulates Sirt1-Mediated Lipogenic Signaling Pathways Through Α4*-Nicotinic Acetylcholine Receptors In Hepatocytes., 2023 University of Louisville
Ethanol Dysregulates Sirt1-Mediated Lipogenic Signaling Pathways Through Α4*-Nicotinic Acetylcholine Receptors In Hepatocytes., Caitlin Christina Wilkerson
Electronic Theses and Dissertations
Alcohol-associated liver disease (ALD) is a broad spectrum of diseases ranging from steatosis to severe hepatic cirrhosis, none of which have any FDA approved therapies. Downregulation of hepatic Sirtuin 1 (Sirt1) activity by ethanol has been shown to lead to an upregulation of the pro-lipogenic gene targets under its jurisdiction, resulting in increased lipogenesis and triglyceride accumulation. It was hypothesized that ethanol acts on α4*-nicotinic acetylcholine receptors (α4*-nAChRs) in hepatocytes to decrease Sirt1 expression, which ultimately dysregulates lipid metabolic homeostasis. Ethanol’s effects were investigated in cultured AML12 hepatocytes and in WT primary mouse hepatocytes acutely exposed to ethanol. Consistent with …

Investigating The Effects Of Subchronic Dietary Zinc Supplementation On Diet-Induced Metabolic Dysfunction-Associated Steatotic Liver Disease., Oluwanifemi Esther Bolatimi
Electronic Theses and Dissertations
Zinc deficiency is associated with metabolic dysfunction-associated steatotic liver disease (MASLD). Previous studies show zinc supplementation improves steatosis, but its therapeutic effects in established MASLD remain unclear. We developed a model to characterize the effects of zinc supplementation on high-fat diet (HFD) induced MASLD and hypothesized established MASLD would be attenuated. Mice were fed control diet or HFD for 12 weeks and then grouped into normal or zinc-supplemented diets for 8 additional weeks. At euthanasia, plasma and liver tissues were collected for phenotypic analysis. Twelve weeks of HFD altered glucose clearance and body composition. Eight weeks of subsequent zinc supplementation …

Electronic Theses and Dissertations
Heterocyclic amines (HCAs) are mutagens generated when cooking meat for prolonged periods of time or until well-done. Recent epidemiological studies reported significant associations between dietary HCA exposure and insulin resistance and type II diabetes. However, no previous studies have examined if HCAs, independent of meat consumption, contributes to pathogenesis of insulin resistance or metabolic disease. It is well known that HCAs require hepatic bioactivation by cytochrome P450 1A2 (CYP1A2) and N-acetyltransferase 2 (NAT2). NAT2 expresses a well-defined genetic polymorphism in humans that, depending on the combination of NAT2 alleles, correlate to rapid, intermediate, or slow acetylator phenotypes that exhibit differential …

Regular physical activity is a proven routine for weight management in addressing obesity. Another method that has gained attention for its health benefits is intermittent fasting (IF). Physical and cognitive abilities while on these routines are poorly understood in the obese population. Sixty-five male Sprague Dawley rats at 7 weeks of age were subjected to diet-induced obesity by feeding a high-fat diet (HFD) or a standard diet (SD) for 8 weeks, after which behavioral testing was performed to detect any changes in physical and cognitive abilities. Rats from the HFD-fed (now considered obese) and SD-fed groups were then subjected to …
