Where To Build Food Banks: A Machine Learning Approach, Gavin Ruan

The Journal of Purdue Undergraduate Research

Over 44 million Americans currently suffer from food insecurity, of whom 13 million are children. Food insecurity has been shown to cause a wide range of both physical and developmental issues. Across the United States, thousands of food banks and pantries serve as vital sources of food and other forms of aid for food-insecure families. By optimizing food bank locations, food banks and their resources would become more accessible to families who desperately require it. The aim of this paper is to build a machine learning framework that is able to optimize food bank locations and to consider factors such …

American Globality And The Us Prison Regime: State Violence And White Supremacy From Abu Ghraib To Stockton To Bagong Diwa, Dylan Rodriguez

Kritika Kultura

What do we make of the abiding significance of state-sanctioned human captivity and imprisonment on a massive, unprecedented scale as a primary American modality of civilization? Democracy? Modernity and (postmodern) Nation-building? The American prison intertwines as it animates two structural logics: 1) white supremacy as a historical modality of social (dis)organization, and 2) the circulation, militarization, and mobilization of allegedly local or domestic US social formations across global geographies, including and beyond the Philippines. This paper considers the formation of the United States prison industrial complex as an epochal global regime that is integral to the fabric of an incipient …

Tnf Prevents Establishment Of Anti-Tumor Immunity And Elucidates Toxicities Following Myxoma Virus Based Oncolytic Virotherapy, Miriam Beatriz Valenzuela Cardenas

Biomedical Sciences ETDs

Tumor Necrosis Factor Alpha (TNF) can lead to tumor regression through its direct cytolytic activity, yet it has also been implicated to facilitate tumor progression. This scenario complicates the efficacy and applicability of TNF based therapeutics as treatment for malignancies. In the context of oncolytic virotherapy (OV) which uses replicating viruses to treat tumors and acts by triggering production of pro-inflammatory cytokines, exploring such mechanisms is vital. Here we show that a Myxoma based oncolytic virus (vPD1/IL12) can induce large amounts TNF. The presence of TNF in the context of vPD1/IL12 plays a detrimental role both for tumor regression by …

5-Fluorouracil Induced Oxidative Stress Is Variable Across Triple Negative Breast Cancer Cell Lines, Rachel L. Walker

Departmental Honors & Graduate Capstone Projects

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer with treatment limited to chemotherapy. However, not all patient tumors respond to chemotherapy. The variable cytotoxic effects of chemotherapies may be due to how cancer cells regulate reactive oxygen species (ROS). In this study, we examined two mouse breast cancer cell lines: 4T1 and EO771, vary when treated with hydrogen peroxide (H2O2) and 5-Fluorouracil (5FU), known ROS-inducing substances. In 4T1 cells H2O2 increased oxidized DNA but caused minimal cell death. While in EO771 cells that same amount of H2O2 caused complete apoptosis. Cell number, ROS, and cell death showed …

Decentralized And Divided: Philadelphia’S Public Assistance System And Community-Based Initiatives, Gianna Casey, Shari Orisich

Honors Theses

Public assistance programs and community-based initiatives have aided Philadelphian’s residents in a cohesive effort to fill the gaps of community-needs. While both are inherently different in their methodologies and executions, their structures are built upon a collective foundation of legislative principles and policy-based ordinances in Philadelphia. These concepts, first began with poor laws and religious organizations in the 19th century, have turned into a complex system that has fallen tremendously short of sufficiently addressing the specialized needs of Philadelphian families. The surrounding laws for public assistance program administration (e.g. TANF and WIC), are founded within the objectives of these poor …

Targeting Myeloid Cell Iron Metabolism In Salmonella-Induced Colitis, Mariella Arcos Padilla

Biomedical Engineering ETDs

Salmonellosis is a severe infection caused by Salmonella enterica serovar Typhimurium, leading to significant global morbidity and mortality.

Previous studies have shown that mice lacking the iron storage protein ferritin heavy chain (FTH1) in myeloid cells exhibit worsened Salmonella infection. Nuclear receptor co-activator 4 (NCOA4) directs FTH1 autophagic degradation to release iron from storage during conditions of low iron. However, the role of myeloid NCOA4 in regulating bacterial infections remains unclear.

Here, we found that myeloid NCOA4 deficiency augments spleen iron levels and increases cellular iron accumulation, oxidative stress, and ferroptosis in bone marrow-derived macrophages (BMDM) cells. This deficiency also …
