As focus for exploration of Mars transitions from current robotic explorers to development of crewed missions, it remains important to protect the integrity of scientific investigations at Mars, as well as protect the Earth's biosphere from any potential harmful effects from returned martian material. This is the discipline of planetary protection, and the Committee on Space Research (COSPAR) maintains the consensus international policy and guidelines on how this is implemented. Based on National Aeronautics and Space Administration (NASA) and European Space Agency (ESA) studies that began in 2001, COSPAR adopted principles and guidelines for human missions to Mars in 2008. …


Threading A Decolonial Feminist Response To Covid-19: One Community Psychologist's Reflection On The Assemblages Of Violence, Jesica S. Fernandez Mar 2024

Threading A Decolonial Feminist Response To Covid-19: One Community Psychologist's Reflection On The Assemblages Of Violence, Jesica S. Fernandez

Ethnic Studies

To challenge and interrogate the assemblages of violence produced by racial capitalism, and exacerbated by the COVID-19 pandemic, community psychologists must engage in a transdisciplinary critical ethically reflexive practice. In this reflexive essay, or first-person account, I offer a decolonial feminist response to COVID-19 that draws strength from the writings of three women of Color decolonial and postcolonial feminist thinkers: Gloria E. Anzaldúa, Sylvia Wynter, and Arundhati Roy. Through their writings I share my reflections on the sociopolitical moment associated with COVID-19. Of importance, I argue in support of engaging a decolonial feminist standpoint to understand the inequitable and dehumanizing …

Staphylococcus Aureus Oleate Hydratase Produces Ligands That Activate Host Ppara, Christopher D. Radka, Matthew W. Frank, Tyler S. Simmons, Cydney N. Johnson, Jason W. Rosch, Charles O. Rock

Markey Cancer Center Faculty Publications

Commensal gut bacteria use oleate hydratase to release a spectrum of hydroxylated fatty acids using host-derived unsaturated fatty acids. These compounds are thought to attenuate the immune response, but the underlying signaling mechanism(s) remain to be established. The pathogen Staphylococcus aureus also expresses an oleate hydratase and 10- hydroxyoctadecanoic acid (h18:0) is the most abundant oleate hydratase metabolite found at Staphylococcal skin infection sites. Here, we show h18:0 stimulates the transcription of a set of lipid metabolism genes associated with the activation of peroxisome proliferator activated receptor (PPAR) in the RAW 264.7 macrophage cell line and mouse primary bone marrow-derived …

In the United States, most real-world estimates of COVID-19 vaccine effectiveness are based on data drawn from large health systems or sentinel populations. More data is needed to understand how the benefits of vaccination may vary across US populations with disparate risk profiles and policy contexts. We aimed to provide estimates of mRNA COVID-19 vaccine effectiveness against moderate and severe outcomes of COVID-19 based on state population-level data sources. Using statewide integrated administrative and clinical data and a test-negative case-control study design, we assessed mRNA COVID-19 vaccine effectiveness against SARS-CoV-2-related hospitalizations and emergency department visits among adults in South Carolina. …


Extramedullary Hematopoiesis In Cancer, Derek A G Barisas, Kyunghee Choi Mar 2024

Extramedullary Hematopoiesis In Cancer, Derek A G Barisas, Kyunghee Choi

2020-Current year OA Pubs

Hematopoiesis can occur outside of the bone marrow during inflammatory stress to increase the production of primarily myeloid cells at extramedullary sites; this process is known as extramedullary hematopoiesis (EMH). As observed in a broad range of hematologic and nonhematologic diseases, EMH is now recognized for its important contributions to solid tumor pathology and prognosis. To initiate EMH, hematopoietic stem cells (HSCs) are mobilized from the bone marrow into the circulation and to extramedullary sites such as the spleen and liver. At these sites, HSCs primarily produce a pathological subset of myeloid cells that contributes to tumor pathology. The EMH …

Approximately five million Ukrainians were displaced to the EU/EEA following the Russian invasion of Ukraine. While tuberculosis (TB) notification rates per 100,000 Ukrainians in the EU/EEA remained stable, the number of notified TB cases in Ukrainians increased almost fourfold (mean 2019-2021: 201; 2022: 780). In 2022, 71% cases were notified in three countries, and almost 20% of drug-resistant TB cases were of Ukrainian origin. Targeted healthcare services for Ukrainians are vital for early diagnosis and treatment, and preventing transmission.

Hydrogen sulfide (H2S) is a noxious, potentially poisonous, but necessary gas produced from sulfur metabolism in humans. In Down Syndrome (DS), the production of H2S is elevated and associated with degraded mitochondrial function. Therefore, removing H2S from the body as a stable oxide could be an approach to reducing the deleterious effects of H2S in DS. In this report we describe the catalytic oxidation of hydrogen sulfide (H2S) to polysulfides (HS2+n−) and thiosulfate (S2O32−) by poly(ethylene glycol) hydrophilic carbon clusters (PEG-HCCs) and poly(ethylene glycol) oxidized activated charcoal (PEG-OACs), examples of oxidized carbon nanozymes (OCNs). We show that OCNs oxidize H2S …

Bacterial type IV secretion systems (T4SSs) are a versatile family of macromolecular translocators, collectively able to recruit diverse DNA and protein substrates and deliver them to a wide range of cell types. Presently, there is little understanding of how T4SSs recognize substrate repertoires and form productive contacts with specific target cells. Although T4SSs are composed of a number of conserved subunits and adopt certain conserved structural features, they also display considerable compositional and structural diversity. Here, we explored the structural bases underlying the functional versatility of T4SSs through systematic deletion and subunit swapping between two conjugation systems encoded by the …

Weed Detection Using Lightweight Deep Learning Models With Transfer Learning And Hyperparameter Optimization, Ali Shaheen

Masters Theses & Doctoral Dissertations

In agriculture, the presence of weeds adversely impacts yield. Confronting this challenge manually requires continuous and labor-intensive field monitoring processes. Artificial intelligence, notably deep learning is one the most promising for weed detection, particularly when deployed to edge devices. However, these edge devices have limited computational resources, making it challenging to deploy large Deep Learning (DL) models often resulting in a performance-size trade-off. This research proposes a three-pronged approach that leverages DL lightweight architectures (LWA) to optimize for size and minimize computational resources at the edge, transfer learning to mitigate constraints associated with limited data commonly encountered in this domain, …


Understanding Provider Perspectives: Catalysts And Challenges Of Intelligent Clinical Decision Support Systems, Andrew Behrens Mar 2024

Understanding Provider Perspectives: Catalysts And Challenges Of Intelligent Clinical Decision Support Systems, Andrew Behrens

Masters Theses & Doctoral Dissertations

The study aims to understand the providers' perspectives of Intelligent Clinical Decision Support Systems (ICDSS). Providers are the key users of ICDSS. ICDSS uptake is heavily reliant on providers. However, providers have a powerful sense of personal identity due to their prestige, high autonomy, and socially accepted role. Currently, providers are resisting ICDSS. ICDSS resistance is due to poor fit with workflow, lack of relevant output and usefulness, insensitivity to complex patients, autonomy challenges, and an impact on the provider-patient relationship. Recently, researchers have overlooked the providers' contextual perspectives of ICDSS. The study addressed the research gap by understanding the …
