Mutation of KRAS in endothelial cells (KRAS-EC) leads to intracerebral hemorrhage (ICH) in brain arteriovenous malformations (bAVM), resulting in severe disabilities or even death. However, it is unclear what causes this hemorrhagic conversion of bAVM. Here, using a locally established, clinically-relevant sporadic bAVM mouse model, created by overexpressing mutant KRAS (KRASG12V) in the brain EC, we demonstrate that KRAS-EC act as trigger for microglia (MG) activation and infiltration of macrophages (Mϕ). Using three-dimensional immunostaining approach with cleared human and mouse bAVM tissues, we demonstrate an abundance of MG/Mϕ around the bAVM nidus. The presence of MG/Mϕ are correlated to the …

College of Health Professions Faculty Papers

RAD52 is a conserved member of the homologous recombination repair (HRR) apparatus from yeast to humans. Mutating conserved amino acids in the internal and external DNA binding domains of the human RAD52 protein (HsRAD52) has discrete effects in vitro. Previous studies have shown that HsRAD52 supports multiple mechanisms of HRR in budding yeast, suggesting the utility of this model system for exploring the correspondence between losses of HsRAD52 function in vitro and their impact in vivo. We report that disrupting the internal and external DNA binding domains of HsRAD52 produced distinct effects on the repair of genomic DNA double-strand breaks …

Dysregulated ribosome biogenesis and p53 mutations are known to play oncogenic roles in various cancers, including pancreatic cancer. In this study, we demonstrated the therapeutic potential of BMH-21, a pharmacologic inhibitor of RNA polymerase I, against pancreatic cancer by uncovering a novel molecular mechanism involving RPA194-mediated ubiquitination of mutant p53 without affecting the ubiquitination of wild-type p53. Our key findings are that (i) BMH-21 selectively induces apoptosis and cell growth inhibition of pancreatic cancer cells with no effect on normal human pancreatic ductal epithelial cells; (ii) BMH-21 degrades RPA194; (iii) BMH-21 inhibits recruitment of both RPA194 and RPA135 on rDNA …

Foundation models have emerged as powerful feature extractors in computational pathology. However, they typically omit mechanisms for leveraging the global spatial structure of tissues and the local contextual relationships among diagnostically relevant regions-key elements for understanding the tumor microenvironment. Multiple instance learning (MIL) remains an essential next step following the foundation model, designing a framework to aggregate patch-level features into slide-level predictions. We present EAGLE-Net, a structure-preserving, attention-guided MIL architecture designed to augment prediction and interpretability. EAGLE-Net integrates multi-scale absolute spatial encoding to capture global tissue architecture, a top-K neighborhood-aware loss to focus attention on local microenvironments, and background suppression …

Radiation therapy is integral to the treatment regimens of over 50% of cancer patients. However, it is not biologically targeted to just the tumor, leading to adverse effects in peritumoral normal tissue. Selective uptake of gold nanoparticles (AuNPs) by tumors realizes tumor-specific radiosensitization via increased secondary electron release from high atomic number gold atoms. Here, we review AuNP-mediated radiosensitization and outline strategies to optimize tumor-targeted AuNP delivery. Modifying the physicochemical characteristics of AuNPs, including size, shape, charge, and surface chemistry, can increase their ability to evade the reticuloendothelial system (RES) and penetrate the dense tumor stromal architecture, thereby promoting tumor …

These fractions are strongly controlled by soil physicochemical properties, necessitating site-specific remediation strategies. Methods: This study developed a site-specific Pb immobilization framework linking amendment selection to soil geochemistry and sustainability considerations. Pb-contaminated residential soils from three U.S. cities, San Antonio (alkaline), Baltimore (acidic), and Detroit (near-neutral), were treated with gypsum, biochar + lime, and alum, respectively. Changes in Pb speciation were tracked using sequential extraction over 7, 30, and 90 days. Results: All amendments significantly reduced exchangeable Pb (F1) and …

What Goals? Which Point? Whose Purpose? A Critical Engagement With Sport Internalism, Francisco Javier Lopez Frias

Kinesiology and Health Science Faculty Publications

In this article, I critique the dominance of internalism in sport philosophy and outline an alternative theoretical framework that integrates internal and external elements while striving to transcend the dichotomous language used to conceptualize sport. The analysis begins by claiming that internalism conflates three fundamental teleological aspects of sport: goals, point, and purposes. I argue that this conflation limits internalism’s ability to explain the complexity of sporting practices. By carefully distinguishing these elements, I illustrate their distinct roles in shaping sport and explore how they interact. I conclude by proposing that the alternative pluralist framework briefly sketched here enables a …

Cover Crop Functional Groups Controls Decomposition And Nutrient Release In Conservation Tillage-Based Corn Production Systems, Puja Sapkota

Tennessee State University Alumni Theses and Dissertations

Grass-legume cover crop mixtures are promoted to balance ecosystem services, but predicting their decomposition and nutrient release remains a challenge. A two-year litterbag study investigated the decomposition of cereal rye, crimson clover, their field mixture, and a gradient of biomass proportions in a no-till corn system. Monocultures exhibited a strong functional dichotomy where rye decomposed slowly with a large recalcitrant fraction and clover decomposed rapidly. The field mixture yielded high biomass similar to rye and exhibited intermediate decomposition kinetics. Crucially, analysis of non-additive effects revealed a fundamental decoupling as the residue mass loss showed context-dependent synergistic acceleration but nitrogen release …

The recent spillover of highly pathogenic influenza A/H5N1 (HPAI-H5N1) viruses to cattle, other mammals, and humans poses a major risk to animal and human health. Virus adaptation to new species highlights the need for effective vaccines for animals and humans. We recently developed a rabies virus-based H5 vaccine encoding the HPAI-H5 antigen and presenting it on the surface of the rabies virus particle. To test the immunogenicity and efficacy of the vaccine in eliciting systemic and mucosal immune response, we vaccinated mice intramuscularly or intranasally with either live or inactivated and adjuvanted vaccine. The vaccine elicited neutralizing antibodies against RABV …

An Autopsy Case Of Extensive Aortic Thrombosis With Acute Kidney Injury As The Sole Clinical Manifestation, Risa Suenaga, Makoto Fukuda, Atsuhiko Suenaga, Yuki Ikeda, Maki Yoshihara, Megumi Nishiyama, Seiichi Kato, Motoaki Miyazono

Children’s Nutrition Research Center Staff Publications

Aortic thrombosis is a rare but life-threatening condition. It typically presents with abdominal or lower-limb ischemia. Although acute kidney injury (AKI) can accompany aortic thrombosis, AKI as the sole clinical manifestation has not been previously reported. A 69-year-old man with extensive atherosclerotic disease and chronic kidney disease presented with severe oliguria. Initial evaluation, including non-contrast computed tomography (CT), did not reveal any aortic abnormalities. Renal Doppler ultrasonography findings and markedly elevated D-dimer levels prompted contrast-enhanced CT, which demonstrated extensive thrombus formation extending from the descending thoracic aorta to the bilateral iliac arteries, with complete occlusion of both renal arteries and …

EGFR-mutant lung adenocarcinomas (LUADs) that are vulnerable to the EGFR antagonist osimertinib (Osi) eventually relapse, owing in part to the emergence of drug-tolerant persister (DTP) cells that arise through epigenetic mechanisms. Intratumoral DTP cells can herald a worse clinical outcome, but the way in which DTP cells influence LUAD progression remains unclear. Osi-resistant (OR) cells exhibit typical DTP cell features, including a propensity to undergo senescence and epithelial-mesenchymal transition (EMT), which can activate heightened secretory states. Therefore, we postulated that OR cells influence LUAD progression through paracrine mechanisms. To test this hypothesis, we utilized congenic pairs of EGFR-mutant LUAD cell …
