From Heroic Imagination To Belonging-Focused Healing: A Tribute To Philip Zimbardo, Agnieszka Wilczynska Jul 2025

From Heroic Imagination To Belonging-Focused Healing: A Tribute To Philip Zimbardo, Agnieszka Wilczynska

Heroism Science

This article offers a reflective account of the Polish adaptation of the Heroic Imagination Project (HIP), a global educational initiative founded by Philip Zimbardo to promote everyday heroism through psychological awareness. As HIP took root in Poland, we developed a robust infrastructure of certified trainers, academic collaborators, and educational centers, reaching over 250 schools and 800 educators. Grounded in core psychological principles -- such as the bystander effect, social conformity, and prejudice -- the program empowered participants to resist negative social influences and cultivate moral courage. The experience also gave rise to Belonging Focus Therapy (BFT), a psychobiological and sociocultural …


Race-Neutral Pft: Implementing Patient Activation Measure Following Race- Neutral Pulmonary Function Testing, Ann M. Way Jul 2025

Race-Neutral Pft: Implementing Patient Activation Measure Following Race- Neutral Pulmonary Function Testing, Ann M. Way

Dissertations

Abstract

Background

The introduction of a race-neutral equation to predict normal values on pulmonary function testing (PFT) has led to changes in the diagnosis of pulmonary diseases previously diagnosed using a race specific equation. Minority patients appear to be most likely impacted by this change, potentially impacting how they self-manage their pulmonary health. Patient self-management can be measured and assessed by using the Patient Activation Measure (PAM) tool.

Purpose

The purpose of this project is to assess patient activation levels amongst minority patients with a new or changed pulmonary diagnosis to identify a possible need for interventions to improve patient …

Faculty, Staff and Students Publications

Malnutrition decreases intestinal bile acids, resulting in inefficient nutrient absorption and impaired catch-up growth. Mechanisms by which bile acid depletion occurs in malnutrition are unknown. Using a mouse model of early-life malnutrition, we explored bile acid homeostasis, focusing on transcriptional repression of CYP7B1, a rate-limiting enzyme in the alternative pathway of bile acid biosynthesis, by SREBP-1c, a master regulator of lipid metabolism. Mice were maintained on a low-protein low-fat or isocaloric control chow until eight weeks of age when livers were harvested for proteome profiling, western blot, RT-qPCR, and chromatin immunoprecipitation. Cultured hepatocytes and mice were treated with the SREBP-1c …

Development And Diversity Of Astrocytes, Michael R Williamson, Sanjana Murali, Benjamin Deneen

Faculty, Staff and Students Publications

Proper development of the central nervous system (CNS) depends on astrocytes, which are the most abundant glial cells in the CNS. Here, we provide an overview of astrocyte ontogeny and morphogenesis, highlighting mechanisms that regulate astrocyte development. In addition, we describe the roles of astrocytes in regulating the development of other CNS cell types, with emphasis on neural circuits and vascular networks. We also discuss evidence for astrocyte diversity and its implications for CNS development. Finally, we pose open questions related to astrocyte development and its intersection with astrocyte diversity.

Cuproptosis is a recently identified form of copper-dependent cell death. Here, we reveal that radiotherapy (RT) induces cuproptosis in cancer cells, independent of apoptosis and ferroptosis, and depletes lipoylated proteins and iron-sulfur (Fe-S) cluster proteins-both hallmarks of cuproptosis-in patient tumors. Mechanistically, RT elevates mitochondrial copper levels by upregulating copper transporter 1 (CTR1) and depleting mitochondrial glutathione, a copper chelator, thereby triggering cuproptosis. Integrated analyses of RNA sequencing (RNA-seq) from radioresistant esophageal cancer cells and single-cell RNA-seq from esophageal tumors of patients unresponsive to RT link radioresistance to the downregulation of BTB and CNC homology 1 (BACH1). This downregulation de-represses the …


Mutant P53 Gain Of Function: Why Many See It, Why Some Do Not, Guillermina Lozano, Carol Prives, Kanaga Sabapathy Jun 2025

Mutant P53 Gain Of Function: Why Many See It, Why Some Do Not, Guillermina Lozano, Carol Prives, Kanaga Sabapathy

Faculty, Staff and Student Publications

Mutations in the TP53 tumor-suppressor gene in human cancer are unique in that 60% to 70% are of the missense variety, resulting in a full-length protein that is often highly expressed in patients' tumors. These missense mutant proteins often exhibit pro-oncogenic activities (referred to as gain of function) in mouse models and human cell lines and correlate with poor cancer prognosis in some cases.

Hyaluronan (HA) in the extracellular matrix promotes epithelial-mesenchymal transition (EMT) and metastasis; however, the mechanism by which the HA network constructed by cancer cells regulates cancer progression and metastasis in the tumor microenvironment (TME) remains largely unknown. In this study, inter-α-trypsin inhibitor heavy chain 2 (ITIH2), an HA-binding protein, was confirmed to be secreted from mesenchymal-like lung cancer cells when cocultured with cancer-associated fibroblasts. ITIH2 expression is transcriptionally upregulated by the EMT-inducing transcription factor ZEB1, along with HA synthase 2 (HAS2), which positively correlates with ZEB1 expression. Depletion of ITIH2 and HAS2 reduced HA matrix formation and the migration and …

The cranial base synchondroses, comprised of opposite-facing bidirectional chondrocyte layers, drive anteroposterior cranial base growth. In humans, RUNX2 haploinsufficiency causes cleidocranial dysplasia associated with deficient midfacial growth. However, how RUNX2 regulates chondrocytes in the cranial base synchondroses remains unknown. To address this, we inactivated Runx2 in postnatal synchondrosis chondrocytes using a tamoxifen-inducible Fgfr3-creER (Fgfr3-Runx2cKO) mouse model. Fgfr3-Runx2cKO mice displayed skeletal dwarfism and reduced anteroposterior cranial base growth associated with premature synchondrosis ossification due to impaired chondrocyte proliferation, accelerated hypertrophy, apoptosis, and osteoclast-mediated cartilage resorption. Lineage tracing reveals that Runx2-deficient Fgfr3+ cells failed to differentiate into osteoblasts. Notably, Runx2-deficient chondrocytes showed …

Background and Objectives: Neuronal nitric oxide synthase (nNOS) overexpressed in melanoma plays a critical role in disease progression. Our previous studies demonstrated that nNOS inhibitors exhibited potent anti-melanoma activity and regulated PD-L1 expressions in the presence of interferon-gamma (IFN-γ). However, the role of nNOS in the melanoma immune response has not been well defined. Methods: Changes in gene expression profiles after nNOS inhibitor treatment were determined by transcriptomic analysis. A melanoma mouse model was used to determine the effects of nNOS inhibition on peripheral T cells and the in vivo anti-tumor activity of combining nNOS inhibitors with immune …

Fears And Pains And Rages: The Psychology Of Gandalf's Anger, Nicholas Birns May 2025

Fears And Pains And Rages: The Psychology Of Gandalf's Anger, Nicholas Birns

Journal of Tolkien Research

We are used to seeing emotions in Tolkien as coded morally. Lust or possessiveness is evil whereas care and forbearance are good. There are some emotions, though, that cross these moral boundaries and one of these is anger Moreover, anger in Tolkien is very coded in terms of gender, as it is nearly always male rage. After examining the cases of Saruman and Wormtongue (angry because the world will not cooperate with their plans) and Thingol (angry because he realizes he has just postponed his doom rather than staved it off), we will examine the case of Gandalf. Gandalf is …

Longevity And Cardiovascular Health: Lessons From The Mediterranean Blue Zones, Lyndsay Bancroft, Miranda Daley, Hitomi Tanizawa

NURS 464: Evidence-Based Nursing Capstone

Cardiovascular diseases are the leading cause of death globally, and poor diet is a leading risk factor for adverse cardiac events (Ahmed et al., 2023). The Mediterranean diet provides protection against coronary heart disease, regardless of the common risk factors for cardiovascular diseases like smoking, hypertension, diabetes, etc (Legrand et al., 2019). Those living in the blue zones of Greece and Italy have far fewer deaths from cardiovascular disease than populations living in other parts of the world (Legrand et al., 2021). This project aims to investigate how the Mediterranean diet has influenced the rates of cardiovascular disease amongst the …

Hypoxia Induced Ribosomal Rna Fragmentation Mediated By Rnase L, Vanessa Kristina Pizutelli, Dimitri G Pestov

Rowan-Virtua Research Day

Ischemic injury contributes to a range of global pathologies. Ischemia/Reperfusion Injury (IRI) is a paradoxical phenomenon that involves an initial restriction of blood flow followed by a sudden restoration of perfusion. This type of injury takes place in conditions such as myocardial infarction, acute kidney disease, and ischemic stroke and often leads to cellular death. Additionally, IRI exacerbates post-surgical outcomes and plays a role in graft dysfunction and transplant rejection. Despite efforts to develop therapies targeting known IRI pathways, clinical trials have largely been unsuccessful, underscoring the need for alternative mechanisms and biomarkers associated with IRI-induced apoptosis. Reactive oxygen species …

The Role Of Tgfβ-Activated Kinase 1 In Fibroblast Differentiation And Cardiac Remodeling After Injury., Daniel Chien Nguyen

Electronic Theses and Dissertations

Immediately following myocardial injury, a robust reparative response is orchestrated through intercellular communication. While various cell populations play critical roles in this process, cardiac fibroblasts have long been recognized as essential mediators of collagen synthesis and scar maturation; however, recent investigations have uncovered significant heterogeneity within the cardiac fibroblast population, revealing distinct subpopulations with roles that extend beyond their traditional functions. Notably, after tissue injury, fibroblasts exposed to damage signals can transition to an inflammatory phenotype, utilizing paracrine and autocrine signaling to coordinate immune cell recruitment and activation. Yet, the mechanisms underlying inflammatory cardiac fibroblast differentiation and their influence on …
