A Comparison Of Whole-Brain Dose During Stereotactic Radiosurgery For Multiple Metastases Across Technology Platforms, Alonso Gutierrez

All Publications

Stereotactic radiosurgery (SRS) is now the gold standard radiation technique for the treatment of multiple brain metastases. By virtue of its targeting accuracy, SRS, relative to whole-brain radiotherapy (WBRT), maximizes both the likelihood of tumor ablation while minimizing irradiation (injury) of the uninvolved brain. The extent to which the latter objective is accomplished varies among radiosurgery platforms. In this study, we used a standardized imaging dataset taken from a patient with 10 random brain metastases to calculate the radiation dose delivered to the uninvolved normal brain across a range of modern SRS delivery platforms. This analysis reveals that irradiation of …

B-Catenin/B-Cell Lymphoma 9 Protein-Protein Interaction Inhibiting Peptidomimetics, Jianfeng Cai, Peng Sang, Yan Shi, Haitao Ji, Min Zhang

USF Patents

Disclosed herein is a series of helical sulfono-γ-AApeptides that mimic the binding mode of the α-helical HD2 domain of B-Cell Lymphoma 9 (BCL9). As disclosed herein, sulfono-γ-AApeptides can structurally and functionally mimic the α-helical domain of BCL9, and selectively disrupt β-catenin/BCL9 PPIs with even higher potency. More intriguingly, these sulfono-γ-AApeptides can enter cancer cells, bind with β-catenin and disrupt β-catenin/BCL PPI, and exhibit excellent cellular activity, which is much more potent than the BCL9 peptide. Furthermore, enzymatic stability studies demonstrated the remarkable stability of the helical sulfono-γ-AApeptides, with no degradation in the presence of pronase for 24 h, augmenting their …

Notch1 Reverses Immune Suppression In Small Cell Lung Cancer Through Reactivation Of Sting, Yoo Sun Kim, Haobin Chen, Et Al.

2020-Current year OA Pubs

Downregulation of antigen presentation and lack of immune infiltration are defining features of small cell lung cancer (SCLC), limiting response to immune checkpoint blockade (ICB). While a high-MHC class I, immune-inflamed subset benefits from ICB, underlying mechanisms of immune response in SCLC have yet to be elucidated. Here we show that in the IMpower133 clinical trial, high, but not low, NOTCH1 expression was significantly associated with longer survival with the addition of ICB to chemotherapy among approximately 80% of SCLC patients with NE-enriched tumors (ASCL1-enriched, HR 0.39, P = 0.0012; NEUROD1-enriched, HR 0.44, P = 0.024). Overexpression or pharmacologic activation …

Despite the success of targeted inhibitors in cutaneous melanoma, therapeutic responses are limited by the aged tumor microenvironment and drug-tolerant residual cells. Given the similarities between drug tolerance and cellular dormancy, we studied the dormancy marker, nuclear receptor subfamily 2 group F member 1 (NR2F1), in response to BRAF-V600E inhibitors (BRAFi) plus MEK inhibitors (MEKi) in BRAF-mutant melanoma models. Transcriptomic analysis of melanoma patient samples treated with BRAFi + MEKi showed increased NR2F1. NR2F1 was highly expressed in the drug-tolerant invasive cell state of minimal residual disease in patient-derived and mouse-derived xenografts on BRAFi + MEKi. NR2F1 over-expression was sufficient …

Rutger Bregman’S Vision: Moral Ambition Without Imagination, Vladimir Snurenco

University Faculty Publications and Creative Works

This review critiques Rutger Bregman’s top-down blueprint—higher taxes, new laws, and big-ticket nonprofits—as a centralized moralism that sidelines the institutions that actually nurture prosperity and dignity: family, church, enterprise, and local associations. I contrast Bregman’s Robin-Hood rhetoric (and his School for Moral Ambition) with a subsidiarity-driven vision rooted in Tocqueville, Kuyper, and Nisbet, and with Michael Pakaluk’s call for vocation within business. Drawing on research by Owen Zidar (the “stealthy wealthy”) and The Millionaire Next Door, I argue Bregman caricatures the rich and misunderstands how wealth is created.

I also question his nonprofit model: celebrating outputs (money raised, nets distributed) …

Proliferative retinopathy is a leading cause of irreversible blindness in humans; however, the molecular mechanisms behind the immune cell–mediated retinal angiogenesis remain poorly elucidated. Here, using single-cell RNA sequencing in an oxygen-induced retinopathy (OIR) model, we identified an enrichment of sorting nexin (SNX)-related pathways, with SNX3, a member of the SNX family that is involved in endosomal sorting and trafficking, being significantly upregulated in the myeloid cell subpopulations of OIR retinas. Immunostaining showed that SNX3 expression is markedly increased in the retinal microglia/macrophages of mice with OIR, which is mainly located within and around the neovascular tufts. Myeloid cell-specific deficiency …

The Potential Benefits Of Co-Design In Dog-Assisted Treatment Programs For Veterans Seeking Mental Health Care, Parvin (Pary) Bahmanyari, Pauleen Bennett, Tiffani Howell

People and Animals: The International Journal of Research and Practice

Veterans are more likely than the general population to experience a range of mental health problems. While many veteran mental health support programs are available, veterans may struggle to access and engage with these services for various reasons (e.g., a stigmatized perception of mental health disorders, mistrust). Animal-assisted services have become more popular in civilian and military health care settings where traditional therapies (e.g., cognitive behavioral therapy) may not always be effective. Assistance dogs, for example, which live with veterans to provide disability support, have been successfully employed for veteran mental health. Unfortunately, a subgroup of veterans may miss out …
