Such effects can certainly impact athletic …


Maternal Mortality: A Growing Health Inequity In America, Michala Geraty Dec 2021

Maternal Mortality: A Growing Health Inequity In America, Michala Geraty

Senior Honors Theses

The United States (U.S.) is known for its quest for knowledge, innovation, and advancements in all disciplines. However, it has the highest maternal mortality ratio (MMR) among developed nations. The US MMR increased from 12.7 to 17.4 per 100,000 live births between 2007 and 2018. Over 60% of these deaths are preventable, indicating room for improvement. African American or non-Hispanic Black women are disproportionately affected, at over twice the rate of their non-Hispanic White and Hispanic counterparts. The proximal (e.g., individual level) determinants have not been able to fully explain these inequities. Using the socio-ecological model and the social determinants …


Evaluation Of Two Neonatal Challenge Models For Broiler Chickens And Their Effects On Early Performance Parameters, Callie Selby Dec 2021

Evaluation Of Two Neonatal Challenge Models For Broiler Chickens And Their Effects On Early Performance Parameters, Callie Selby

Graduate Theses and Dissertations

Formaldehyde fumigation in poultry hatch cabinets has been utilized for sanitation of hatching eggs for over a century. Formaldehyde is utilized to minimize pathogenic microbes on the surface of the egg as well as the microbial bloom during the hatching process. While formaldehyde is effective, its use is regulated in the United States and Europe due to its carcinogenic nature. Formaldehyde has been shown to damage the cuticle of the egg, cause embryonic death, and damage the epithelial lining of the respiratory tract of freshly hatched chicks, predisposing them for respiratory infection. Alternatives for formaldehyde fumigation must be identified and …

Preclinical Development Of Epicertin, A Novel Biotherapeutic For The Treatment Of Ulcerative Colitis., Micaela Ann Reeves Dec 2021

Preclinical Development Of Epicertin, A Novel Biotherapeutic For The Treatment Of Ulcerative Colitis., Micaela Ann Reeves

Electronic Theses and Dissertations

Epicertin (EPT) is a recombinant variant of the cholera toxin B subunit with a C-terminal KDEL endoplasmic retention motif. Previously, orally administered EPT demonstrated mucosal healing activity in acute and chronic dextran sulfate sodium colitis models, indicating its therapeutic potential for ulcerative colitis (UC) treatment. However, oral dosing with EPT requires neutralization of gastric acid prior to administration, hindering its facile application in the treatment of chronic diseases like UC. One solution to this issue is that EPT may also be administered intracolonically without losing efficacy. This work describes the determination of a target intracolonic dose of EPT for future …


Impact Of Pank1 Deletion On Mitochondrial Acetylation And Cardiac Function During Pressure Overload., Timothy N. Audam Dec 2021

Impact Of Pank1 Deletion On Mitochondrial Acetylation And Cardiac Function During Pressure Overload., Timothy N. Audam

Electronic Theses and Dissertations

Recent studies have associated elevated protein acetylation levels with heart failure in humans. Although mechanisms promoting elevated acetylation levels are not fully known, excess acetyl-CoA may drive enzyme-independent acetylation of cardiac proteins. Accumulation of acetyl-CoA depends on the availability of sufficient CoA, whose production is regulated by pantothenate kinases in the CoA biosynthetic pathway. We show that cardiac proteins are hyperacetylated during heart failure in humans and tested in mice whether limiting CoA abundance would improve ventricular remodeling during pressure overload-induced hypertrophy. We limited cardiac CoA levels by deleting the rate-limiting enzyme in CoA biosynthesis, Pank1 (one of three PANK-encoding …


Assessing The Role Of Arsenic Exposure And Mirna-186 In Skin Tumorigenesis And Chromosomal Instability., Angeliki Lykoudi Dec 2021

Assessing The Role Of Arsenic Exposure And Mirna-186 In Skin Tumorigenesis And Chromosomal Instability., Angeliki Lykoudi

Electronic Theses and Dissertations

Chronic arsenic exposure through drinking water is a global health issue, affecting more than 200 million people. Arsenic is a group I human carcinogen and causes chromosomal instability (CIN). Arsenic exposure is the second most cause of skin cancer after UV radiation. MiR-186 is overexpressed in arsenic-induced squamous cell carcinoma relative to premalignant hyperkeratosis. Predicted targets of miR-186 are cell cycle regulators. Thus, we hypothesize that miR-186 overexpression drives malignant transformation of HaCaT cells by induction of CIN. Stable clones of HaCaT transfected with pEP-miR-186 expression vector or empty vector were maintained under puromycin selection were exposed to 0 or …


An Analysis Of Taste Neuron Morphological Variability: Influences Of Neuron Type And Plasticity., Lisa Christina Ohman Dec 2021

An Analysis Of Taste Neuron Morphological Variability: Influences Of Neuron Type And Plasticity., Lisa Christina Ohman

Electronic Theses and Dissertations

Taste neurons are functionally and molecularly diverse, but their morphological diversity was, until recently, completely unexplored. Taste neurons were considered relay cells, communicating information from taste-transducing cells to the brain without variation in morphology. Instead, individual taste neurons are tremendously morphologically variable. To determine how differences in branching relate to the number and types of taste-transducing cells providing neuronal input, I combined sparse cell genetic labeling with a whole-mount immunohistochemistry and analysis workflow. I found that the maximum number of taste-transducing cells capable of providing convergent input onto individual gustatory neurons varied with a range of 1-22 taste-transducing cells. Consistently, …

Examination Of The Association Between C - Reactive Protein(Crp) And Covid-19 Infection Severity And Length Of Hospitalization, Abdulahi Aremu Ayanwale

Open Access Theses & Dissertations

Chronic stress can lead to many systemic complications and low-grade systemic inflammation including increased levels of inflammatory cytokines, such as C-reactive protein (CRP). CRP is a marker of systemic inflammation and is associated with depression and perceived stress. Elevations can result in ineffective immune responses, thereby increasing the risk of complications and mortality from infections. Recent evidence suggests that uncontrolled inflammatory responses associated with COVID 19 are a major determinant of disease severity.  The COVID 19 is transmitted from one person to another through droplets from coughing, sneezing, talking, touching droplets on surfaces and contamination by hand-to-mouth routes. The mechanism …

Does Precise Case Disclosure Limit Precautionary Behavior? Evidence From Covid-19 In Singapore, Aljoscha Janssen, Matthew H. Shapiro

Research Collection School Of Economics

Limiting the spread of contagious diseases can involve both government-managed and voluntary efforts. Governments have a number of policy options beyond direct intervention that can shape individuals’ responses to a pandemic and its associated costs. During its first wave of COVID-19 cases, Singapore was among a few countries that attempted to adjust behavior through the announcement of detailed case information. Singapore's Ministry of Health maintained and shared precise, daily information detailing local travel behavior and residences of COVID-19 cases. We use this policy along with device-level cellphone data to quantify how local and national COVID-19 case announcements trigger differential behavioral …
