Novel Mechanisms Of Neuronal And Hormonal Regulation Of Large Intestinal Electrolyte Transport, Andrew John Nickerson

Graduate Theses, Dissertations, and Problem Reports (ETD)

The mammalian colon plays a vital role in maintaining overall electrolyte and fluid homeostasis in the body, and it possesses the ability to either secrete or absorb water depending upon the needs of the organism. Secretion or absorption of electrolyte ions, such as Na⁺, Cl^- and K⁺, drives the movement of water across the colonic epithelium – the inner gut lining where all transport takes place. Aberrant absorptive and/or secretory activity within the colonic epithelium is central to the pathogenesis of many gastrointestinal diseases, such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), constipation …

Utilizing The Coughing Rat Model Of Pertussis To Improve Vaccine Efficacy, Jesse M. Hall

Graduate Theses, Dissertations, and Problem Reports (ETD)

Pertussis, also known as whooping cough, is a respiratory disease caused by the highly contagious, Gram-negative pathogen Bordetella pertussis (Bp). Infection occurs through inhalation of aerosolized droplets containing Bp, which then colonizes ciliated epithelial cells of the respiratory tract. Here, Bp expresses toxins and virulence factors that lead to leukocyte recruitment, paroxysmal cough, and impairment of host innate responses. Currently, in developed countries, acellular pertussis vaccines (aP; DTaP; Tdap) are used to prevent Bp infection and whooping cough disease. However, we currently realize that the aP vaccine efficacy quickly wanes resulting in a reemergence of pertussis. Recent …

Role Of Vascular Endothelial Growth Factor Receptor 2 Pathway Due To Preeclampsia: A Review, Firdous Ali

Williams Honors College, Honors Research Projects

Preeclampsia is a pregnancy complication that is characterized mainly by hypertension in the mother. The exact pathogenesis of preeclampsia is unknown, although the disease is attributed to a number of factors such as angiogenic factor levels and endothelial dysfunction. Presently, the control program for the disease involves the delivery of the fetus and the placenta. There is a need to develop novel therapies that would control preeclampsia from the moment it is diagnosed to minimize the effects on the mother and child. VEGF is a protein involved in the pathogenesis of the condition. The defect in one of its receptors, …

Minimally Invasive Repair Of Elongated Chordae Tendineae In The Mitral Valve, Walid Abuhashim, Diana Albaba, Austin Ghiates, Rebecca Leiter, Mary Robakowski

Williams Honors College, Honors Research Projects

In the United States, about 4 million people have been estimated to suffer from severe mitral valve regurgitation [5]. Due to the high risks involved, about half of those patients are ineligible for surgery to repair the valve, because of their poor health [6]. Elongation of the chordae tendineae has been found to be one of the significant causes of regurgitation. To address this, the team has developed a device called “Chord Fastener”, which will restore proper function to the valve via shortening of the chordae tendineae [1]. Via this shortening mechanism, the device will reduce mitral valve regurgitation and …

MODULATION OF PHARYNGEAL HEALTH IN BACTERIAL DIET-DEPENDENT SURVIVAL

by

DENIZ SIFOGLU

August 2021

Advisor: Dr. Joy Alcedo Major: Biological Sciences Degree: Doctor of Philosophy Both diet and bacterial microbiome modulate insulin signaling, which regulates key physiological processes that are important for survival. However, the mechanisms through which diet and the microbiome modulate insulin signaling remain unclear. To understand these mechanisms, I turned to the nematode worm C. elegans, whose diet consists of different types of bacteria. Like humans and other animals, C. elegans has to modulate its responses to its diet and to bacteria to optimize its survival. Because …

Hypochlorite-Mediated Oxidation Of Dopamine: Implications In Parkinson’S Disease And Manganism, Praneet Kaur Marwah

Wayne State University Dissertations

Both Parkinson’s disease and manganism (a condition caused by chronic exposure to excessive levels of manganese) affect the extrapyramidal system of the brain, disrupt dopaminergic signaling and cause similar motor symptoms. While there is no physiological explanation for the susceptibility of dopamine-rich regions of the brain in both disorders, dopamine itself is a likely candidate. Dopamine can undergo both enzymatic and spontaneous oxidation, and the principal product of dopamine oxidation in vivo is cysteinyl dopamine. We demonstrate here that hypochlorous acid, which is produced in the brain by the enzyme myeloperoxidase, converts cysteinyl dopamine into a neurotoxic dihydrobenzothiazine, DHBT-1, that …

Journal Articles: Biochemistry & Molecular Biology

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy with high mortality, poor prognosis, and palliative treatments, due to the rapid upregulation of alternative compensatory pathways and desmoplastic reaction. miRNAs, small non-coding RNAs, have been recently identified as key players regulating cancer pathogenesis. Dysregulated miRNAs are associated with molecular pathways involved in tumor development, metastasis, and chemoresistance in PDAC, as well as other cancers. Targeted treatment strategies that alter miRNA levels in cancers have promising potential as therapeutic interventions. miRNA-345 (miR-345) plays a critical role in tumor suppression and is differentially expressed in various cancers, including pancreatic cancer (PC). The underlying …

Batra, Sidharth Mahapatra

Journal Articles: Biochemistry & Molecular Biology

Haploinsufficiency of chromosome 17p and c-Myc amplification distinguish group 3 medulloblastomas which are associated with early metastasis, rapid recurrence, and swift mortality. Tumor suppressor genes on this locus have not been adequately characterized. We elucidated the role of miR-212-3p in the pathophysiology of group 3 tumors. First, we learned that miR-212-3p undergoes epigenetic silencing by histone modifications in group 3 tumors. Restoring its expression reduced cancer cell proliferation, migration, colony formation, and wound healing in vitro and attenuated tumor burden and improved survival in vivo. MiR-212-3p also triggered c-Myc destabilization and degradation, leading to elevated apoptosis. We then isolated an …

Physician Knowledge, Attitudes, And Behaviors Towards Registered Dietitian Nutritionists, Amy Motley Jones

UNF Graduate Theses and Dissertations

Diet is increasingly linked with overall quality of life, and a healthy diet is now being considered one of the cornerstones of preventative care. Physicians rely on Registered Dietitian Nutritionists (RDNs) as most doctors lack the nutrition knowledge to properly treat their patients, especially during their residency. Little published information exists on the specific collaboration of RDNs and resident physicians. This study aimed to determine whether mentoring with an RDN increased physician nutrition knowledge, increased consults to RDNs, and whether physician attitudes improved regarding their understanding of the role of the RDN in healthcare. Knowledge or attitude alone are not …
