Factors Contributing To Diminished Long-Term Outcomes Of Secondary Infections, Alia Tayara

Honors Theses

It is widely known that patients suffer diminished long-term outcomes in the years following secondary infections, infectious diseases that occur during or after treatment of a primary infection such as influenza or COVID-19. One common secondary infection is pneumonia, which has become the most fatal hospital-acquired infection. The bacterium responsible for pneumonia is known as Pseudomonas aeruginosa. The cytotoxic supernatant in these studies was generated from a PA103 strain of Psuedomonas aeruginosa with a type III secretion system that maintains the ability to transfer exoenzymes ExoU and ExoT into target cells during infection. The focus of the following studies was …

Assessment Of Hypothermia As A Correlate Of Pde4 Inhibitor-Induced Nausea In Mice, Marianna Susan Oditt

Honors Theses

Type-4-cAMP-phosphodiesterases (PDE4s) are a group of isoenzymes that hydrolyze the second messenger cyclic adenosine monophosphate (cAMP). PDE4 inhibitors have many therapeutic uses including reducing inflammation, however, they also have side effects like nausea and emesis, which have diminished the clinical utility of PDE4 inhibitors. When administered to mice, PDE4 inhibitors have been shown to cause hypothermia. Given that nausea and emesis in humans are also associated hypothermia, this project served to determine whether PDE4 inhibitor-induced hypothermia may represent a correlate of nausea and/or emesis in mice. To this end, the current literature was screened for articles that explore nausea, emesis …

Mimicking The Effect Of Prolactin On Stat3/Stat5 Activity In Breast Cancer, Jennifer N. Barbuto, Sarah R. Walker

Honors Theses and Capstones

Signal transducers and activators of transcription (STAT) 3 and 5 are commonly constitutively activated in breast cancer. STAT5 can outcompete STAT3 and reduce cell proliferation and metastasis. STAT5 activation is stimulated by prolactin, a natural hormone that can be harmful at high levels. The aim of this study is to identify some possible previously developed drugs that mimic the effect of prolactin and STAT5 without the added risk in MDA-MB231 breast cancer cells. Using the CLUE database query app and STAT5 up- and downregulation signatures, three drugs (X, K, and M) were chosen based on their similarity in signatures to …

The Sleep Of Shift Workers In A Remote Mining Operation: Methodology For A Randomized Control Trial To Determine Evidence-Based Interventions, Gemma Maisey, Marcus Cattani, Amanda Devine, Johnny Lo, Ian C. Dunican

Research outputs 2014 to 2021

© Copyright © 2021 Maisey, Cattani, Devine, Lo and Dunican. Shiftwork may adversely impact an individual’s sleep-wake patterns and result in sleep loss ( < 6 h. following night shift), due to the circadian misalignment and the design of rosters and shifts. Within a mining operation, this sleep loss may have significant consequences due to fatigue, including an increased risk of accidents and chronic health conditions. This study aims to (i) determine the efficacy of an intervention that comprises a sleep education program and biofeedback through a smartphone app on sleep quality, quantity, and alertness (ii) determine the prevalence of risk for a potential sleep disorder, and (iii) quantify and describe the sleep habits and behaviors of shift workers in a remote mining operation. This study consists of a randomized controlled trial whereby eighty-eight shift workers within a remote mining operation are randomized to a control group or one of three different treatment groups that are: (i) a sleep education program, (ii) biofeedback on sleep through a smartphone app, or (iii) a sleep education program and biofeedback on sleep through a smartphone app. This study utilizes wrist-activity monitors, biomathematical modeling, and a survey instrument to obtain data on sleep quantity, quality, and alertness. A variety of statistical methods will determine the prevalence of risk for a potential sleep disorder and associations with body mass index, alcohol, and caffeine consumption. A generalized linear mixed model will examine the dependent sleep variables assessed at baseline and post-intervention for the control group and intervention groups, as well as within and between groups to determine changes. The findings from this study will contribute to the current understanding of sleep and alertness behaviors, and sleep problems and disorders amongst shift workers. Importantly, the results may inform fatigue policy and practice on interventions to manage fatigue risk within the mining industry. This study protocol may have a broader application in other shiftwork industries, including oil and gas, aviation, rail, and healthcare.

Viability Of Physiologically Timed Relaxation Interventions In Children With Asd, Nicholas Mendez

CMC Senior Theses

Autism Spectrum Disorder (ASD) is an increasingly common developmental disorder that changes how people experience the world and affects individuals’ social interactions and often leads to many adverse behaviors. Current literature dictates that a primary contributor to these adverse behaviors is that those with ASD have difficulty determining their own emotional states and determining the physiological signals that their body sends them. A study by Dr. Sarabadani et al. determined that it was possible to monitor the physiology of an individual with ASD and correlate certain signals to emotions, such as stress. These findings indicate the feasibility of establishing a …
