Human Movement Sciences Faculty Publications

Polychlorinated biphenyls (PCBs) are persistent environmental organic pollutants known to have detrimental health effects. Using a mouse model, we previously demonstrated that PCB126 exposure before and during pregnancy and throughout the perinatal period adversely affected offspring glucose tolerance and/or body composition profiles. The purpose of this study was to investigate the glucose tolerance and body composition of offspring born to dams exposed to PCB126 during the nursing period only. Female ICR mice were bred, and half of the dams were exposed to either vehicle (safflower oil) or 1 µmole PCB126 per kg of body weight via oral gavage on postnatal …

School of Public Health Faculty Publications

Excessive sugar-sweetened beverages (SSB) consumption and abdominal obesity have been independently linked to numerous disorders, including diabetes and elevated C-reactive protein (CRP). This study aimed to explore the association between SSB intake, abdominal obesity, and inflammation in normal and prediabetic adults. Sugar intake from SSBs was calculated from 24-h dietary recalls and further classified into non-, medium-, and high-intake. The status of non- and prediabetes was identified based on hemoglobin A1c level. All analyses were performed under a survey module with appropriate sampling weights to control for the complex survey design. A total of 5250 eligible adults without diabetes were …

Metabolic Foundations Of Exercise-Induced Cardiac Growth., Kyle Levi Fulghum

Electronic Theses and Dissertations

Regular aerobic exercise promotes physiological cardiac growth, which is an adaptive response thought to enable the heart to meet higher physical demands. Cardiac growth involves coordination of catabolic and anabolic activities to support ATP generation, macromolecule biosynthesis, and myocyte hypertrophy. Although previous studies suggest that exercise-induced reductions in cardiac glycolysis are critical for physiological myocyte hypertrophy, it remains unclear how exercise influences the many interlinked pathways of metabolism that support adaptive remodeling of the heart. In this thesis project, we tested the general hypothesis that aerobic exercise promotes physiological cardiac growth by coordinating myocardial metabolism to promote glucose-supported anabolic pathway …

Radiologic Contrast-Induced Transmetallation In Mineral Rich Fruits: X-Ray Imaging To Understand Heat Cycling During Climate Change And Map Metal Redistribution In Biological Media For Biomedical Applications, Lin Mousa, Hayley Sanchez, Subhendra Sarkar, Zoya Vinokur

Publications and Research

Heat cycling due to climate change can affect hydrated protein or carbohydrate functions, the latter is not well studied. The project started with involving the study of heat-stressed carbohydrate behavior when bulk water was partly stripped from carbohydrates in model microwaved fruits and vegetables, like apples and sweet potatoes (that are mineral-rich) and was set in mineral exchange competition with toxic metals like Gadolinium and chelating complexes like iodinated EDTA. These are common radiologic contrast medias that strongly absorb x-rays and are currently implicated in man-made environmental toxins. Our goal was to map diffusion of injected heavy atoms as well …

Cardiometabolic Responses In Individuals With/Without Family History Of Type 2 Diabetes, Christopher J. Cavazos

MEDI 8127 Scholarly Activities Pre-Clerkship

Intro: Type 2 diabetes (T2D) has become a national epidemic and is a disease that greatly affects the Rio Grande Valley. Many individuals in the United States, especially in the Rio Grande Valley, have a family history of T2D. Previous evidence has shown that those with a family history of T2D are metabolically inflexible, have a decreased ability to clear circulating glucose, and poor postprandial microvascular recruitment in skeletal muscle tissue. The aforementioned occurs in otherwise healthy individuals with a family history of T2D to nearly the same extent as those who have T2D. Previous studies have not shown where …

Identification And Characterization Of Butyrate-Producing Species In The Human Gut Microbiome, Grace Maline

Theses/Capstones/Creative Projects

Inflammatory Bowel Diseases (IBD) including ulcerative colitis, indeterminate colitis, and Crohn’s disease are increasingly common conditions that places a high physical and financial burden on individuals and global healthcare systems. Though many treatments exist for these conditions, their unpredictable nature and causation make them difficult to manage across the variety of IBD patients. Additionally, many of these treatments come with undesirable side effects or modes of delivery. Therefore, it is worthwhile to explore the use of Short Chain Fatty Acids (SCFAs) such as butyrate whose affects in the human gut include decreased inflammation and decreased risk of colorectal cancer. As …

Ketogenic Diet As A Preventative Measure Or Treatment Option For Osteoarthritistargeting Nfl Athletes As A High-Risk Group, Kelsi J. Smith

Selected Honors Theses

Osteoarthritis (OA) is a prevalent joint disease that results from the degradation of articular cartilage, leading to inflammation, pain, and eventual joint failure. At one time, it was thought that OA was only the result of the natural decline experienced in old age; however, various risk factors have now been identified that may contribute to an increased risk for developing OA. Risk factors may include joint loading, altered biomechanics, obesity, and joint injury, to which athletes are exposed at a high rate. NFL athletes are one group of athletes that have continued to show a high prevalence of arthritis in …

Synthesis Of Glycopharmaceuticals For The Treatment Of Microbial Sepsis, Nicholas Forsythe, Alexei Demchenko, Catherine Alex

Undergraduate Research Symposium

Carbohydrates (glycans) form the basis of all living organisms and, consequently, are ubiquitous both in nature as biologically active compounds and in medicine as pharmaceuticals. One important application of carbohydrate-based drugs (glycopharmaceuticals) is the treatment of microbial sepsis, an acute illness that causes 100,000+ human deaths annually in the US alone. Exposure of the patient’s blood system to E. coli bacteria causes a massive, and often fatal, immune response. One important cellular receptor that senses the bacterium and is critically involved in triggering the immune response is CD14. Significant efforts by our team and others have been made to develop …

Reversible Glucan Phosphorylation In The Red Alga, Cyanidioschyzon Merolae, Corey Owen Brizzee

Theses and Dissertations--Molecular and Cellular Biochemistry

Starch and glycogen are an essential component for the majority of species and have been developed to maintain homeostasis in response to environmental changes. Water-soluble glycogen is an excellent source of quick, short-term energy in response to energy demands. In contrast, plants and algae have developed the macromolecule starch that is elegantly suitable for their dependence on external circumstances. Semi-crystalline starch is water-insoluble and inaccessible to most amylolytic enzymes, thus plants and algae have developed a coordinated system so that these enzymes can gain access to the denser starch energy cache. Starch-like semi-crystalline polysaccharides are also found in red algae, …

When looking at biomolecules, carbohydrate represent a large group of macromolecules that play an important role in the body. Most importantly, carbohydrates provide an energy supply for organisms, but it is proven that they are also involved in a myriad of other processes. Furthermore, synthesizing these molecules leads to advancements in chemistry, such as drug design, and other structures such as glycolipids play important roles in the immune system. Understanding this, an efficient and reliable way to create these carbohydrates is needed.

The protection and deprotection manipulations of carbohydrates play an essential role in synthetic carbohydrate chemistry.¹ Using benzyl …

Arachidin 3 Modulation Of Lipid Metabolism In Rotavirus Infections, Stormey Wisdom

Electronic Theses and Dissertations

Rotavirus (RV) can cause severe and deadly gastroenteritis in young children, infants, and immunocompromised individuals. Previous studies have shown that arachidin 3 (A3) inhibits RV replication, and that RV replication is dependent on the presence of lipids. This study investigated the alteration of lipid metabolism by A3 in RV infected HT29.f8 cells. A decrease in the RV regulation of lipid biosynthesis genes was observed with the addition of A3 using qRT-PCR. Also, immunofluorescent and histochemical staining for neutral fats, a major component of cellular lipid droplets, revealed an increased accumulation with both RV and RV+A3 when compared to no virus …

Glycosaminoglycan Lyases In The Preparation Of Oligosaccharides, Alhumaidi B. Alabbas

Theses and Dissertations

Glycosaminoglycans are heterogeneous polysaccharides that mediate important biological functions. There has been considerable interest in deciphering the precise GAG sequences that are responsible for protein interactions. In fact, several GAG oligosaccharides have been discovered to date as targeting proteins with higher level of specificity. Yet, it has been difficult to develop GAG oligosaccharides as drugs. One of the key reasons for this state of art is that GAG synthesis is extremely challenging and is highly structure-specific. Thus, much of the biology and pharmacology of GAG remains unknown and unexploited to date.

An alternative approach is to prepare GAG oligosaccharides using …

Roles Of Gabab, Muscarinic And Nicotinic Receptor Signaling In The Acquisition And Expression Of Fructose And Fat-Conditioned Flavor Preferences And Acquisition Of Quinine-Conditioned Flavor Avoidances In Rats, Francis M. Rotella

Dissertations, Theses, and Capstone Projects

In addition to increased intake of sweet solutions by mammals, learning, particularly classically-conditioned “Pavlovian-like” learning, also plays an important role. An orosensory conditioned flavor preference (CFP) can be elicited by pairing one novel flavor (conditioned stimulus, CS+) with a fructose solution and a second novel flavor (CS-) with a saccharin solution. Rats will prefer the CS+ flavor in a subsequent 2-bottle choice test with both flavors mixed in saccharin. Previous pharmacological analyses revealed that systemic administration of dopamine (DA) D1 and D2 as well as NMDA, but not opioid, receptor antagonists eliminated the acquisition (learning) of fructose-CFP. Further, expression of …

Central nervous system (CNS) disorders are becoming a major societal problem. Examples of well-known CNS disorders are: neurodegenerative disorders such as Parkinson's, Huntington's and Alzheimer’s diseases, epilepsy/seizures, addiction, bipolar disorder, catalepsy, meningitis, migraines, attention deficit/hyperactivity disorder (ADHD), and multiple sclerosis. CNS disorders can be caused by various factors and therefore can affect ages, genders and races of all.

The population of patients with CNS disorders is increasing and a significant percentage of patients have symptoms that are not controlled by existing treatments. In addition, since CNS disorders are chronic disorder, there is no cure and thus the patients have to …

Diversity Oriented Synthesis, Characterization And Anti-Cancer Activity Of Killer Peptide Nucleolipid Bioconjugates, Niki K. Rana

Seton Hall University Dissertations and Theses (ETDs)

The killer peptide sequence D-(KLAKLAK)₂ has been originally designed and developed as an antibacterial agent. Despite having excellent cytotoxicity towards bacteria, this sequence maintains low cell cytotoxity in malignant mammalian cell types such as cancer. The chemical basis for its selectivity has been attributed to its poly(cationic) amphiphilic nature, which facilitates cell permeability across the negatively charged bacterial membrane, but with limited permeability across the zwitterionic membrane of mammalian cells. The positively charged D-(KLAKLAK)₂ sequence has been found to accumulate on the surface of the mitochondria causing dissipation of the negatively charged mitochondrial membrane potential. This charge disruption …

Mouth Exposure To Carbohydrate Prior To Exercise Possibly Impairs The Efficacy Of Carbohydrate Mouth Rinsing During Exercise, Kevin Decker

Masters Theses, 2010-2019

Decker K. P., M. J. Saunders, N. D. Luden, C. J. Womack, and N. J. Hladick. Mouth Exposure to Carbohydrate Prior to Exercise Possibly Impairs the Efficacy of Carbohydrate Mouth Rinsing during Exercise. Purpose: Carbohydrate mouth-rinsing (CHO-MR) during intense endurance exercise has been associated with improved cycling performance, due to neurological influences. However, prior studies have reported the efficacy of CHO-MR is attenuated following a pre-exercise meal. To determine if this outcome is related to desensitization of CHO receptors (rather than metabolic effects following digestion), this study will investigate whether CHO-MR prior to exercise influences cycling performance when CHO-MR …
