Cross-Sectional Survey Of Patients, Caregivers, And Physicians On Diagnosis And Treatment Of Brain Metastases, Manmeet Ahluwalia

All Publications

Background. The development of brain metastases (BM) is one of the most feared complications of cancer due to the substantial neurocognitive morbidity and a grim prognosis. In the past decade, targeted therapies and checkpoint inhibitors have demonstrated promising intracranial response rates for tumors of multiple histologies. As overall survival for these patients improves, there is a growing need to identify issues surrounding patient survivorship and to standardize physician practice patterns for these patients. To date, there has not been an adequate study to specifically explore these questions of survivorship and practice standardization for patients with advanced cancer and BM.

Anisotropic Optical Responses Of Layered Thallium Arsenic Sulfosalt Gillulyite, Ravi P. N. Tripathi, Jie Gao, Xiaodong Yang

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Multi-element two-dimensional (2D) materials hold great promise in the context of tailoring the physical and chemical properties of the materials via stoichiometric engineering. However, the rational and controllable synthesis of complex 2D materials remains a challenge. Herein, we demonstrate the preparation of large-area thin quaternary 2D material flakes via mechanical exfoliation from a naturally occurring bulk crystal named gillulyite. Furthermore, the anisotropic linear and nonlinear optical properties including anisotropic Raman scattering, linear dichroism, and anisotropic third-harmonic generation (THG) of the exfoliated gillulyite flakes are investigated. The observed highly anisotropic optical properties originate from the reduced in-plane crystal symmetry. Additionally, the …

Experiences Of Low-Income Student-Parents At A Community College During The Coronavirus (Covid-19) Pandemic, Marlena Yvonne Jarboe

Educational Leadership & Workforce Development Theses & Dissertations

Twenty-two percent of United States undergraduate students are parents (Cruse, et al., 2020). Referred to as student-parents, they are most likely to have low-incomes and attend community colleges (Cruse, et al., 2019; Gault et al., 2014). They tend to reduce their course loads and drop out of college due to work-life balance challenges even though they typically have better grade point averages than their non-parent peers (Cruse et al., 2019; Manze, et al., 2021; Peterson, 2016).

The problem to be addressed was how community college instructors, leaders, and legislators can support low-income student-parents’ persistence toward a postsecondary credential. There is …

The Christian Right In Translation: Christian Conservative Discourse In Contemporary American Literature, Elizabeth Richardson Duke

English Theses and Dissertations

Religion in contemporary American politics and religion in contemporary American Literature: are they independent phenomena? Literary scholars have largely assumed so. Scholars have attended to nontraditional, liberal religion in postwar American literature, while overlooking how this literature represents and critiques the rise of the Christian Right. Since white evangelical and fundamentalist Christians allied with the Republican party in the late 1970s, Christian conservatives have transformed American politics. As the GOP’s most influential interest group, the Christian Right has set the terms for many of the last four decades’ most contentious and consequential debates. Historians, political scientists, and contemporary American writers …

Educating Asian American College Students On The Importance Of Community And Mentorship, Jeah Limbag

Capstone Projects and Master's Theses

Many college students may find it challenging to discover and create a supportive and consistent community or establish meaningful relationships in school. Asian American college students, in particular, have cultural values, experiences, and ideologies that can limit seeking mentors and establishing a social support network. The consequences of this could be increased feelings of loneliness and isolation, worse mental health, lower academic performance, lower attendance, and an increased likelihood of dropping out of school. To address these challenges, I have created an interactive presentation bringing awareness of the importance of mentorship and community to students in the Asian and Pacific …

The fungus Candida albicans is an opportunistic pathogen that can exploit imbalances in microbiome composition to invade its human host, causing pathologies ranging from vaginal candidiasis to fungal sepsis. Bacteria of the genus Lactobacillus are colonizers of human mucosa and can produce compounds with bioactivity against C. albicans. Here, we show that some Lactobacillus species produce a small molecule under laboratory conditions that blocks the C. albicans yeast-to-filament transition, an important virulence trait. It remains unexplored whether the compound is produced in the context of the human host. Bioassay-guided fractionation of Lactobacillus-conditioned medium linked this activity to 1-acetyl-β-carboline (1-ABC). We …

Reintegrating Biology Through The Nexus Of Energy, Information, And Matter, Kim L. Hoke, Sara L. Zimmer, Adam B. Roddy, Mary Jo Ondrechen, Craig E. Williamson, Nicole R. Buan

Department of Biochemistry: Faculty Publications

Information, energy, and matter are fundamental properties of all levels of biological organization, and life emerges from the continuous flux of matter, energy, and information. This perspective piece defines and explains each of the three pillars of this nexus. We propose that a quantitative characterization of the complex interconversions between matter, energy, and information that compose this nexus will help us derive biological insights that connect phenomena across different levels of biological organization. We articulate examples from multiple biological scales that highlight how this nexus approach leads to a more complete understanding of the biological system. Metrics of energy, information, …

Narrative Review-Drug Delivery In Age-Related Macular Degeneration, Rachel Israilevich, Raziyeh Mahmoudzadeh, Mirataollah Salabati, David Xu

Wills Eye Hospital Papers

This narrative review highlights routes of ocular drug delivery for age-related macular degeneration (AMD). AMD is the leading cause of irreversible blindness in industrialized countries and accounts for 8.7% of blindness worldwide. Advanced AMD can be classified into two subtypes: late-stage dry AMD [known as geographic atrophy (GA)] and neovascular AMD (nAMD). GA is often bilateral and results from progressive and irreversible loss of photoreceptors and areas of the retinal pigment epithelium. Wet AMD is characterized by angiogenesis from the choroid to the normally avascular regions underneath the retinal pigment epithelium (RPE) or retina, a process known as choroidal neovascularization …

Movin’ On Up? A Survey Experiment On Mobility Enhancing Policies, Jared Barton, Xiaofei Pan

Economics Faculty Journal Articles

We use a nationwide survey experiment in the United States to measure whether information on intergenerational economic mobility or policy-specific arguments influence support for six pro-mobility policies advocated by political entrepreneurs. We find the information treatments do not affect support, but the argument treatments significantly increase support for three of the policies. We also include a behavioral measure by allowing respondents the opportunity to write their U.S. Senators. We find argument treatments significantly increase the likelihood that letters address economic mobility and significantly promote advocacy for that policy in the letter, but no increase in advocacy from the information treatments. …
