Faculty Research 2024

Although patient-derived xenografts (PDX) are commonly used for preclinical modeling in cancer research, a standard approach to in vivo tumor growth analysis and assessment of antitumor activity is lacking, complicating the comparison of different studies and determination of whether a PDX experiment has produced evidence needed to consider a new therapy promising. We present consensus recommendations for assessment of PDX growth and antitumor activity, providing public access to a suite of tools for in vivo growth analyses. We expect that harmonizing PDX study design and analysis and assessing a suite of analytical tools will enhance information exchange and facilitate identification …

Integrative Approaches To Evaluate Challenges Faced By Songbirds During Migration And Associated Physiological Trade-Offs, Gabriella L. Orfanides

Theses

Migration is a demanding time for birds, and birds face numerous physiological, behavioral, and environmental challenges. As migratory birds balance the costs of numerous stressors during migration, this could result in detrimental physiological trade-offs. Understanding the trials and trade-offs that birds encounter during migration has important conservation implications. I utilized two component studies to better understand challenges encountered by migratory songbirds as well as to identify physiological metrics that may provide insight into these challenges. For the first study, I used nested PCR and DNA sequencing to determine parasite prevalence and diversity of avian haemosporidians in Canada Warblers (Cardellina canadensis) …

Medicare Drug Price Negotiation Program Draft Guidance, Fred Ledley M.D., Edward Zhou Pharmd, Paula Chaves Da Silva Ph.D.

CISI Publication

This comment focuses on Section 50.1, provisions 1 & 3 of the draft guidance regarding the negotiation of a “maximum fair price” under the Inflation Reduction Act (IRA), research and development (R&D) costs of the primary manufacturer, and prior federal financial support for novel therapeutic discovery and development. Specifically, we argue that a negotiated, “maximum fair price” must consider both public sector (federal) and private sector (manufacturer) investments and provide returns to both commensurate with the scale and risk of their investments. This comment addresses three issues and makes specific recommendations regarding each:

1. In negotiating a “maximum fair price,” both …

Optimizing Seaweed Biomass Production ‑ A Two Kelp Solution, Michael Stekoll, Alf Pryor, Alexandra Meyer, Hauke L. Kite-Powell, David Bailey, Kendall Berbery, Clifford A. Goudey, Scott Lindell, Loretta Roberson, Charles Yarish

Faculty, Staff, and Students

Interest in farming kelps has grown beyond using kelp for food, feed or biofuels. There is considerable interest in generating biomass from seaweed for use in bioplastics and other products that would substitute for petroleum-derived products. For these uses to be viable, large amounts of biomass are needed. Very large kelp farms can be expensive to build and maintain, leading to the need to optimize the biomass per unit area. Although close spacing of growlines can lead to poor growth, a viable approach may be to grow two species of kelps together: one that hangs down and one that is …

The Fishing Cat: New Insights On Distribution In The Northern Sector Of Chitwan National Park, Nepal, Rupesh Maharjan, Rama Mishra, Jhamak Bahadur Karki

School of Earth, Environmental, & Marine Sciences Faculty Publications

Fishing cat Prionailurus viverrinus (Bennett, 1833) is an elusive and medium-sized feline species with distinguished marking patterns on their head and body separating them from other feline species. Despite being distributed widely among diverse geographic locations, their abundance has declined due to significant habitat loss and human disturbances. There exists a substantial research gap regarding their abundance and distribution in Nepal. In this article, we presented the updated documentation of the fishing cat distribution in the northern sector of Chitwan National Park through our species-focused camera trapping survey. The study was carried out between April and May 2021 with a …

The Design, Construction, And Testing Of Nucleic Acid Vaccines Against Salmonella Enterica Subspecies Enterica Serovar Javiana, Alexis A. Nguyen

LSU Master's Theses

Salmonella spp. is a Gram-negative bacterium that has the ability to replicate within a variety of hosts, or within the environment, including water, soil, and vegetation. These characteristics, coupled with the zoonotic nature of non-typhoidal Salmonella, pose a significant public health concern. Salmonella is the leading cause of foodborne illnesses worldwide, and in the United States alone, the economic impact due to non-typhoidal Salmonella illnesses in 2013 was estimated to be $3.7 billion, the majority of which were due to mortalities. In a time of rising antibiotic resistance, antibiotics are no longer considered the most effective treatment for …

Faculty, Staff and Student Publications

The biomedical research community addresses reproducibility challenges in animal studies through standardized nomenclature, improved experimental design, transparent reporting, data sharing, and centralized repositories. The ARRIVE guidelines outline documentation standards for laboratory animals in experiments, but genetic information is often incomplete. To remedy this, we propose the Laboratory Animal Genetic Reporting (LAG-R) framework. LAG-R aims to document animals' genetic makeup in scientific publications, providing essential details for replication and appropriate model use. While verifying complete genetic compositions may be impractical, better reporting and validation efforts enhance reliability of research. LAG-R standardization will bolster reproducibility, peer review, and overall scientific rigor.

Disambiguation Of Aerococcus Urinae Species Diversity, Brian Ian Choi

Dissertations

Aerococcus urinae is an uncommon inhabitant of the human urogenital tract. The Gram-positive bacterium has been implicated in a wide range of urinary tract diseases that, if left untreated or undiagnosed, can progress to severe disease such as infective endocarditis. Comparative analysis of 115 A. urinae isolates from infection episodes of urinary tract infection, bacteremia, infective endocarditis, urgency urinary incontinence, stress urinary incontinence, interstitial cystitis / painful bladder syndrome, and asymptomatic individuals reveal substantial diversity with respect to predicted virulence factors, metabolism, and observed biofilm behavior. Through whole genome sequencing analysis, these strains can be reorganized into six new taxonomic …

Unveiling The Path To Lgbtq+ Inclusive And Culturally Competent Healthcare: A Multi-Dimensional Examination Of Trainings, Policies, And Perspectives, Hyunmin Yu

Dissertations

LGBTQ+ individuals encounter enduring discrimination and adverse healthcare encounters within the healthcare system, with profound implications for their health and wellbeing. Policymakers have advocated for the adoption of LGBTQ+ inclusive and culturally competent healthcare, including training for health professionals, to promote health equity among LGBTQ+ populations. However, implementation of these policies within healthcare systems varies, posing structural and individual-level barriers. In this dissertation, I employ an ecological model of LGBTQ+ health disparities and a conceptual model of determinants of health disparities in vulnerable populations within the healthcare system to examine the impact of structural inequities on the implementation of LGBTQ+ …

The Evolving Paradigm Of Antibody-Drug Conjugates Targeting The Erbb/Her Family Of Receptor Tyrosine Kinases, Peyton High, Cara Guernsey, Shraddha Subramanian, Joan Jacob, Kendra S Carmon

The Brown Foundation: Institute of Molecular Medicine

Current therapies targeting the human epidermal growth factor receptor (HER) family, including monoclonal antibodies (mAbs) and tyrosine kinase inhibitors (TKIs), are limited by drug resistance and systemic toxicities. Antibody-drug conjugates (ADCs) are one of the most rapidly expanding classes of anti-cancer therapeutics with 13 presently approved by the FDA. Importantly, ADCs represent a promising therapeutic option with the potential to overcome traditional HER-targeted therapy resistance by delivering highly potent cytotoxins specifically to HER-overexpressing cancer cells and exerting both mAb- and payload-mediated antitumor efficacy. The clinical utility of HER-targeted ADCs is exemplified by the immense success of HER2-targeted ADCs including trastuzumab …

Towards An Interdisciplinary “Science Of The Mind”: A Call For Enhanced Collaboration Between Philosophy And Neuroscience, Alessandra Buccella, Uri Maoz, Liad Mudrik

Psychology Faculty Articles and Research

In recent decades, the neuroscientific community has moved from describing the neural underpinnings of mental phenomena—as characterized by experimental psychology and philosophy of mind—to attempting to redefine those mental phenomena based on neural findings. Nowadays, many are intrigued by the idea that neuroscience might provide the “missing piece” that would allow philosophers (and, to an extent, psychologists, too) to make important advances, generating new means that these disciplines lack to close knowledge gaps and answer questions like “What is Free Will?” and “Do humans have it?.” In this paper, we argue that instead of striving for neuroscience to replace philosophy …

A Therapist Perspective: Gender Differences In Treatment Recommendations For Adults With Adhd, Inattentive Presentation, Casey Redus

Walden Dissertations and Doctoral Studies

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder with onset during childhood and often persisting into adulthood. Statistics show that more men are diagnosed with ADHD than women, and that women are more often diagnosed with ADHD inattentive type. Treatment for ADHD has not focused on non-psychopharmacology gender-based treatment recommendations, and this has been identified as requiring further research. This qualitative study explored therapists' process in making treatment recommendations for women versus men diagnosed with ADHD inattentive subtype. Social role theory was used to underpin the research. The participants of the study included ten licensed psychologists in the state …

Characterization Of The Glyoxal Response In Pseudomonas Aeruginosa, Christopher James Corcoran

Dissertations

The toxic dialdehyde glyoxal is found in all domains of life and results as a by-product from a variety of metabolic activities such as DNA oxidation, lipid peroxidation, and autoxidation of sugars such as glucose. If allowed to accumulate, the reactive aldehyde groups of glyoxal have the ability to react with a plethora of molecules including, DNA, lipids, and protein side chains. Most notably, glyoxal can react with arginine, lysine, and cysteine residues, forming irreversible covalent modifications known as advanced glycation end products (AGEs). These glyoxal-derived AGEs can impair protein function, leading to cellular toxicity and eventual cell death. Due …

The activated B cell (ABC) subset of diffuse large B-cell lymphoma (DLBCL) is characterized by chronic B-cell receptor signaling and associated with poor outcomes when treated with standard therapy. In ABC-DLBCL, MALT1 is a core enzyme that is constitutively activated by stimulation of the B-cell receptor or gain-of-function mutations in upstream components of the signaling pathway, making it an attractive therapeutic target. We discovered a novel small-molecule inhibitor, ABBV-MALT1, that potently shuts down B-cell signaling selectively in ABC-DLBCL preclinical models leading to potent cell growth and xenograft inhibition. We also identified a rational combination partner for ABBV-MALT1 in the BCL2 …

Influential Individuals Can Promote Prosocial Practices In Heterogeneous Societies: A Mathematical And Agent-Based Model, Stefani A. Crabtree, Colin D. Wren, Avinash Dixit, Simon A. Levin

Environment and Society Faculty Publications

In this paper, we examine how different governance types impact prosocial behaviors in a heterogenous society. We construct a general theoretical framework to examine a game-theoretic model to assess the ease of achieving a cooperative outcome. We then build a dynamic agent-based model to examine three distinct governance types in a heterogenous population: monitoring one's neighbors, despotic leadership, and influencing one's neighbors to adapt strategies that lead to better fitness. In our research, we find that while despotic leadership may lead towards high prosociality and high returns it does not exceed the effects of a local individual who can exert …

A Pan-Cancer Patient-Derived Xenograft Histology Image Repository With Genomic And Pathologic Annotations Enables Deep Learning Analysis, Brian S White, R Jay Mashl, Sherri R Davies, Ryan C Fields, Jacqueline L Mudd, Ramaswamy Govindan, Shunqiang Li, Li Ding, Et Al.

2020-Current year OA Pubs

Patient-derived xenografts (PDX) model human intra- and intertumoral heterogeneity in the context of the intact tissue of immunocompromised mice. Histologic imaging via hematoxylin and eosin (H&E) staining is routinely performed on PDX samples, which could be harnessed for computational analysis. Prior studies of large clinical H&E image repositories have shown that deep learning analysis can identify intercellular and morphologic signals correlated with disease phenotype and therapeutic response. In this study, we developed an extensive, pan-cancer repository of >1,000 PDX and paired parental tumor H&E images. These images, curated from the PDX Development and Trial Centers Research Network Consortium, had a …
