Impact Of Physical Inactivity On Glucose Metabolism And Skeletal Muscle Secretions In Healthy Trained Rats And Potential Counteracting Effect Of Exercise And Protocatechuic Acid, Hira Shakoor Sep 2023

Impact Of Physical Inactivity On Glucose Metabolism And Skeletal Muscle Secretions In Healthy Trained Rats And Potential Counteracting Effect Of Exercise And Protocatechuic Acid, Hira Shakoor

Dissertations

Modern societies have significantly transformed people's lifestyles, leading to a substantial increase in physical inactivity, which concerns 23% of adults and 81% of adolescents worldwide. Physical inactivity is a major factor contributing to the emergence of chronic diseases, most prominently Type 2 Diabetes (T2D), which exhibits a high prevalence in many countries. T2D is characterized by elevated blood glucose levels due to cells’ responsiveness to insulin. The shift towards inactivity likely occurred more rapidly than the genome's capacity to adapt, resulting in the metabolic dysfunctions underlying the development of T2D. Skeletal muscle is crucial in the onset of these metabolic …

Chemistry & Biochemistry Faculty Publications and Presentations

Human zoonotic infection with Campylobacter is a major cause of gastroenteritis in the United States and worldwide. Listeria monocytogenes causes a potentially fatal infection in humans and is often attributed to contaminated food. Genetic typing has demonstrated that Campylobacter infection is often associated with the consumption of contaminated poultry products, with Campylobacter often colonizing the poultry gastrointestinal tract, while listeriosis is commonly associated with the consumption of contaminated ready-to-eat (RTE) foods. In this study, a strain of endospore-forming bacterium (strain NH) that is bactericidal towards the human food pathogens Campylobacter jejuni and Listeria monocytogenes was identified and characterized. Transwell experiments …

The Dangers Of Staphylococcus Aureus And Antimicrobial Resistance, Madison Pines Sep 2023

The Dangers Of Staphylococcus Aureus And Antimicrobial Resistance, Madison Pines

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Methicillin-resistant Staphylococcus aureus (MRSA) is the etiological agent responsible for many problematic infections. The signs and symptoms of an infection caused by MRSA differ based on the route of transmission and type of infection. Staphylococcus aureus can secrete toxins that act as virulence factors and aid host invasion. Obesity, old age, being a health care worker, playing contact sports, living in a crowded place, hospitalization, recent antibiotic use, and HIV patients are more at risk of developing an infection caused by MRSA. An abundance of factors has contributed to antimicrobial resistance, like misuse of antibiotics in clinical and agricultural settings …

Il-15 And Ifn-G Regulation In Murine Nk Cells, Maria Cimpean Sep 2023

Il-15 And Ifn-G Regulation In Murine Nk Cells, Maria Cimpean

Arts & Sciences Graduate Student Theses and Dissertations

Natural killer (NK) cells are innate lymphoid cells that play important roles in antiviral and antitumor responses through their cytotoxicity mechanisms and the ability to modulate immune responses through production of cytokines such as IFN-g. NK cells are able to execute these responses rapidly and without prior sensitization due to their germline-encoded receptors. Recent work in the field of immunometabolism has highlighted the impact that changes in cellular metabolism can have on immune cell function, including NK cell effector functions. Our lab has previously reported activation-specific metabolic requirements for IFN-g production by resting murine NK cells in vitro, which IL-15 …

Effects Of Acid Hydrolysis Level Prior To Heat-Moisture Treatment On Properties Of Starches With Different Crystalline Polymorphs, Ana Gonzalez, Ya-Jane Wang

Food Science Faculty Publications and Presentations

Highly crystalline starches find applications as resistant starch because of their improved thermal stability and reduced enzyme susceptibility. Both acid hydrolysis (AH) and heat-moisture treatment (HMT) have been used to alter starch gelatinization properties and digestibility. This study investigated the effects of varying AH levels (0–9%) prior to HMT on the structures and properties of starches with different crystalline polymorphs, including the A-type corn starch, the B-type potato starch, and the C-type pea starch. HMT resulted in significant increases in gelatinization temperatures and significant decreases in gelatinization enthalpy and α-amylase digestion for all three starches. When combined AH with HMT, …

Clostridial cellulitis or dermatitis affects commercial turkey flocks, primarily as they approach market age. In the field, this disease has been effectively controlled with antibiotics, but alternatives to antibiotics are needed. Bacterin-toxoid vaccination programs have been shown to prevent clostridial diseases in other species, including humans. Results from previous field studies indicate that vaccination with an experimental whole-cell Clostridium septicum (CS) bacterin-toxoid oil emulsion vaccine reduced clostridial dermatitis-associated mortality and antibiotic usage for some commercial turkey flocks, but vaccination was not always efficacious. To improve vaccine efficacy, studies were conducted to optimize the antigenic component of the experimental …

Cell Entry And Release Of Quasi-Enveloped Human Hepatitis Viruses, Anshuman Das, Efraín E Rivera-Serrano, Xin Yin, Christopher M Walker, Zongdi Feng

Faculty, Staff and Student Publications

Infectious hepatitis type A and type E are caused by phylogenetically distinct single-stranded, positive-sense RNA viruses that were once considered to be non-enveloped. However, studies show that both are released nonlytically from hepatocytes as 'quasi-enveloped' virions cloaked in host membranes. These virion types predominate in the blood of infected individuals and mediate virus spread within the liver. They lack virally encoded proteins on their surface and are resistant to neutralizing anti-capsid antibodies induced by infection, yet they efficiently enter cells and initiate new rounds of virus replication. In this Review, we discuss the mechanisms by which specific peptide sequences in …

Activating KRAS mutations (KRAS*) in pancreatic ductal adenocarcinoma (PDAC) drive anabolic metabolism and support tumor maintenance. KRAS* inhibitors show initial antitumor activity followed by recurrence due to cancer cell-intrinsic and immune-mediated paracrine mechanisms. Here, we explored the potential role of cancer-associated fibroblasts (CAFs) in enabling KRAS* bypass and identified CAF-derived NRG1 activation of cancer cell ERBB2 and ERBB3 receptor tyrosine kinases as a mechanism by which KRAS*-independent growth is supported. Genetic extinction or pharmacological inhibition of KRAS* resulted in up-regulation of ERBB2 and ERBB3 expression in human and murine models, which prompted cancer cell utilization of CAF-derived NRG1 as a …


Carm1 Arginine Methyltransferase As A Therapeutic Target For Cancer, Margarida Santos, Jee Won Hwang, Mark T Bedford Sep 2023

Carm1 Arginine Methyltransferase As A Therapeutic Target For Cancer, Margarida Santos, Jee Won Hwang, Mark T Bedford

Faculty, Staff and Student Publications

Coactivator-associated arginine methyltransferase 1 (CARM1) is an arginine methyltransferase that posttranslationally modifies proteins that regulate multiple levels of RNA production and processing. Its substrates include histones, transcription factors, coregulators of transcription, and splicing factors. CARM1 is overexpressed in many different cancer types, and often promotes transcription factor programs that are co-opted as drivers of the transformed cell state, a process known as transcription factor addiction. Targeting these oncogenic transcription factor pathways is difficult but could be addressed by removing the activity of the key coactivators on which they rely. CARM1 is ubiquitously expressed, and its KO is less detrimental in …

Background: The current standard operation for proximal gastric and gastroesophageal junction (P/GEJ) cancers with limited esophageal extension is total gastrectomy (TG). TG is associated with impaired appetite and weight loss due to the loss of gastric functions such as production of ghrelin and with anemia due to intrinsic factor loss and vitamin B12 malabsorption. Theoretically, proximal gastrectomy (PG) can mitigate these problems by preserving gastric function. However, PG with direct esophagogastric reconstruction is associated with severe postoperative reflux, delayed gastric emptying, and poor quality of life (QoL). Minimally invasive PG (MIPG) with antireflux techniques has been increasingly performed by experts …

BACKGROUND: Little is known about long-term treatment-related symptoms in older breast cancer survivors. We characterized long-term patient-reported symptoms and examined factors associated with the presence and severity of symptoms, and symptom interference with daily activities.

METHODS: Texas Cancer Registry (TCR) Medicare linkage data was used to identify breast cancer patients age 65 and older with local/regional stage disease diagnosed between 2012-2013. Symptom burden was assessed using breast-specific items from the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE™). Demographic and clinical data also were collected. Logistic regression models were used to assess the association between symptom …

Cancer immunoprevention applies immunologic approaches such as vaccines to prevent, rather than to treat or cure, cancer. Despite limited success in the treatment of advanced disease, the development of cancer vaccines to intercept premalignant states is a promising area of current research. These efforts are supported by the rationale that vaccination in the premalignant setting is less susceptible to mechanisms of immune evasion compared with established cancer. Prophylactic vaccines have already been developed for a minority of cancers mediated by oncogenic viruses (e.g., hepatitis B and human papillomavirus). Extending the use of preventive vaccines to non-virally driven malignancies remains an …

STUDY OBJECTIVES: Chronic intermittent hypoxia due to obstructive sleep apnea (OSA) causes oxidative stress, which may contribute to the pathophysiology of Parkinson's disease (PD). However, the bidirectional relationship between PD and OSA has not been satisfactorily established. The objective of this study was to try to estimate whether there is a bidirectional relationship between PD and OSA through a retrospective cohort study in the South Korean population.

METHODS: This study used data from the Korean National Health Information Database of the National Health Insurance Service, which contains data from 3.5 million individuals evenly distributed. In study 1, patients with OSA …
