Parp Inhibitor Response Is Enhanced In Prostate Cancer When Xrcc1 Expression Is Reduced, Kaveri Goel, Vani Venkatappa, Kimiko L Krieger, Dongquan Chen, Arun Sreekumar, Natalie R Gassman

Faculty, Staff and Students Publications

Prostate cancer (PCa) is the second most common cancer worldwide and the fifth leading cause of cancer-related deaths among men. The emergence of metastatic castration-resistant prostate cancer (mCRPC) after androgen deprivation therapy (ADT) exemplifies the complex disease management for PCa. PARP inhibitors (PARPis) are being tested to treat mCRPC in tumors with defective homologous recombination repair (HRR) to address this complexity. However, increasing resistance towards PARPi in HRR-deficient patients and the low percentage of HRR-defective mCRPC patients requires the identification of new genes whose deficiency can be exploited for PARPi treatment. XRCC1 is a DNA repair protein critical in the …

University Honors Theses

This project investigates the intersectionality between race, mental health, and homelessness, emphasizing the dynamic interplay between structural factors and individual characteristics. Through an integrative literature review, the research addresses the question of how race, mental health, and homelessness are interconnected. The findings suggest a distinct relationship between untreated mental illness and an increased risk of homelessness, particularly among marginalized racial groups. In addition, some mental illnesses, such as anxiety and depression, have a higher incidence among those who face conflict due to racial discrimination. Structural components such as systemic racism in social services and healthcare practices significantly impact access to …

A Comprehensive Literature Review Of Gender Differences In Perception And Response To Stress, Zoe M. Shankland

University Honors Theses

It is well established that psychological stress, whether acute, chronic, or recurring, creates an imbalance in the body’s ability to regulate itself, leading to the potential for long-term disease. This paper looks at the possibility that women (anyone who identifies as a woman) experience more general mental stress than men (anyone who identifies as a man) due to women experiencing unique stressors under a patriarchal society. Men and women live different lives in modern society due to differing societal expectations and biological processes for women (menstruation, pregnancy, menopause). These extra feelings of stress may be tied to traditional gender roles …

Digesting The Details: How Cooking Shapes The Microbiome And Influences Obesity, Tracy Lieu

University Honors Theses

Obesity is a growing global health concern linked to chronic diseases and changes in the gut microbiome. While diet is known to affect gut microbes, less attention has been given to how food processing methods, such as heating, fermentation, and cold processing, change food in ways that influence the gut microbiome and health. This thesis reviews research on how different cooking and preparation techniques affect the availability of nutrients for microbial fermentation and the resulting effects on microbial diversity and metabolism. The findings show that fermentation and cold processing are the most supportive of gut health. These methods help preserve …

Access To Healthcare For Rural Transgender Adults In The United States, Devon Smith

University Honors Theses

Urban and rural healthcare differ significantly in the amount of facilities, providers and kinds of specialty care that are offered in each environment. The United States is split into urban and rural counties in any given region, and based on those population sizes, are the allocation of healthcare resources for residents. In rural areas in the U.S., transgender adults lack access to gender-affirming care and encounter a lack of gender-affirming care providers due to workforce shortages, discrimination, and a lack of cultural competency. To determine if these residents lacked access to care compared with their urban counterparts, I performed a …

Faculty, Staff and Student Publications

Objectives: We investigated whether self-reported vision and hearing were associated with cognitive function and loneliness among Mexican adults aged 50 and older.

Methods: Mexican Health and Aging Study data. Vision/hearing status was self-reported (excellent-very good, good, fair-poor). Cognition was measured using nine tasks. Loneliness was measured using the UCLA Loneliness Scale. Analyses controlled for demographic and health characteristics.

Results: Among 12,353 participants (mean age = 67, 58% female), poor vision, but not hearing, was associated with lower global cognition (β = -0.03, p < .05). Poor vision (OR = 1.57, 95% CI = 1.30-1.91) and hearing (OR = 1.35, 95% CI = 1.14-1.61) were associated with higher odds of being lonely after adjusting for demographics and comorbidities, but not when adjusting for limitations in daily activities and depressive symptoms.

Discussion: Poor vision is a potentially modifiable risk factor for lower cognition and loneliness among Mexican adults. …
