Background: Follicular lymphoma (FL) and marginal zone lymphoma (MZL) are indolent non-Hodgkin lymphomas (iNHL). Median survival for iNHL is approximately 20 years. Because standard treatments are not curative, patients often receive multiple lines of therapy with associated toxicity-rationally designed, combination therapies with curative potential are needed. The immunomodulatory drug lenalidomide was evaluated in combination with rituximab for the frontline treatment of FL in the phase 3 RELEVANCE study. Ibrutinib, an oral Bruton tyrosine kinase inhibitor, is active in NHL and was evaluated in combination with lenalidomide, rituximab, and ibrutinib (IRR) in a phase 1 study.

Methods: The authors conducted an …

Deep Dive Into The Chronic Toxicity Of Tyre Particle Mixtures And Their Leachates, Paul Boisseaux, Cassandra Rauert, Pradeep Dewapriya, Marie Laure Delignette-Muller, Robyn Barrett, Lee Durndell, Florian Pohl, Richard Thompson, Kevin V. Thomas, Tamara Galloway

School of Geography, Earth and Environmental Sciences

Particles from the tread of vehicle tyres are a global pollutant, which are emitted into the environment at an approximate rate of 1.4 kg.year⁻¹ for an average passenger-car. In this study, popular tyre brands were used to generate a tyre tread microparticle mixture. The chronic toxicity of both particles and chemical leachates were compared on a planktonic test species (Daphnia magna). Over 21 days of exposure, pristine tyre tread microparticles were more toxic (LC50 60 mg.L⁻¹) than chemical lechates alone (LC50 542 mg.L⁻¹). Microparticles and leachates showed distinct effects on reproduction and morphological development at …

During aging, blood cell production becomes dominated by a limited number of variant hematopoietic stem cell (HSC) clones. Differentiated progeny of variant HSCs are thought to mediate the detrimental effects of such clonal hematopoiesis on organismal health, but the mechanisms are poorly understood. While somatic mutations in DNA methyltransferase 3A (DNMT3A) frequently drive clonal dominance, the aging milieu also likely contributes. Here, we examined in mice the interaction between high-fat diet (HFD) and reduced DNMT3A in hematopoietic cells; strikingly, this combination led to weight gain. HFD amplified pro-inflammatory pathways and upregulated inflammation-associated genes in mutant cells along a pro-myeloid trajectory. …

Natural killer (NK) cell deficiency (NKD) occurs when an individual’s major clinical immunodeficiency derives from abnormal NK cells and is associated with several genetic etiologies. Three categories of β actin-related diseases with over 60 ACTB (β actin) variants have previously been identified, none with a distinct NK cell phenotype. An individual with mild developmental delay, macrothrombocytopenia, susceptibility to infections, molluscum, and EBV-associated lymphoma had functional NK cell deficiency for over a decade. A de novo ACTB variant encoding G342D β actin was identified and was consistent with the individual’s developmental and platelet phenotype. This novel variant also was found to …

Tissue-Resident Memory T Cell Signatures From Single-Cell Analysis Associated With Better Melanoma Prognosis, Chongming Jiang, Cheng-Chi Chao, Jianrong Li, Xin Ge, Aidan Shen, Vadim Jucaud, Chao Cheng, Xiling Shen

Faculty, Staff and Students Publications

Tissue-resident memory T cells (TRM) are a specialized T cell population residing in peripheral tissues. The presence and potential impact of TRM in the tumor immune microenvironment (TIME) remain to be elucidated. Here, we systematically investigated the relationship between TRM and melanoma TIME based on multiple clinical single-cell RNA-seq datasets and developed signatures indicative of TRM infiltration. TRM infiltration is associated with longer overall survival and abundance of T cells, NK cells, M1 macrophages, and memory B cells in the TIME. A 22-gene TRM–derived risk score was further developed to effectively classify patients into low- and high-risk categories, distinguishing overall …

The initial step in estrogen-regulated transcription is the binding of a ligand to its cognate receptors, named estrogen receptors (ERα and ERβ). Phytochemicals present in foods and environment can compete with endogenous hormones to alter physiological responses. We screened 224 flavonoids in our engineered biosensor ERα and ERβ PRL-array cell lines to characterize their activity on several steps of the estrogen signaling pathway. We identified 83 and 96 flavonoids that can activate ERα or ERβ, respectively. While most act on both receptors, many appear to be subtype-selective, including potent flavonoids that activate ER at sub-micromolar concentrations. We employed an orthogonal …

A Journey In Science: Molecular Vaccines For Global Child Health In Troubled Times Of Anti-Science, Peter J Hotez

Faculty, Staff and Students Publications

My scientific life in translational medicine runs in two parallel, yet often converging paths. The first, is four-decade-long commitment to develop new vaccines for parasitic and neglected tropical diseases, as well as pandemic threats. This includes a vaccine for human hookworm infection that I began as an MD-PhD student in New York City in the 1980s, and a new low-cost COVID vaccine that reached almost 100 million people in low- and middle-income countries. Alongside this life in scientific research, is one in public engagement for vaccine and neglected disease diplomacy to ensure that people who live in extreme poverty can …

Dolutegravir-Induced Neural Tube Defects In Mice Are Folate Responsive, Gabriel L Tukeman, Hui Wei, Ying L Lin, Bogdan J Wlodarczyk, Richard H Finnell, Robert M Cabrera

Faculty, Staff and Students Publications

Objectives: In 2018, the Botswana Tsepamo Study reported a nine-fold increased risk of neural tube defects in infants whose mothers were treated with dolutegravir (DTG) from the time of conception. As maternal folate supplementation and status is a well known modifier of neural tube defect (NTD) risk, we sought to evaluate birth outcomes in mice fed normal and low folic acid diets treated with DTG during pregnancy.

Design: DTG was evaluated for developmental toxicity using pregnant mice fed normal or low folic acid diet.

Methods: CD-1 mice were provided diet with normal (3 mg/kg) or low (0.3 mg/kg) folic acid. …

A Comparative Analysis Of Tonebp Conditional Knockout Mouse Models Reveals Inter-Dependency Between Compartments Of The Intervertebral Disc, Greig Couasnay, Haley Garcia, Florent Elefteriou

Faculty, Staff and Students Publications

Interactions between notochord and sclerotome are required for normal embryonic spine patterning, but whether the postnatal derivatives of these tissues also require interactions for postnatal intervertebral disc (IVD) growth and maintenance is less established. We report here the comparative analysis of four conditional knockout mice deficient for TonEBP, a transcription factor known to allow cells to adapt to changes in extracellular osmotic pressure, in specific compartments of the IVD. We show that TonEBP deletion in nucleus pulposus (NP) cells does not affect their survival or aggrecan expression, but promoted cell proliferation in the NP and in adjacent vertebral growth plates …

Gastrointestinal immune cells, particularly muscularis macrophages (MM) interact with the enteric nervous system and influence gastrointestinal motility. Here we determine the human gastric muscle immunome and its changes in patients with idiopathic gastroparesis (IG). Single cell sequencing was performed on 26,000 CD45+ cells obtained from the gastric tissue of 20 subjects. We demonstrate 11 immune cell clusters with T cells being most abundant followed by myeloid cells. The proportions of cells belonging to the 11 clusters were similar between IG and controls. However, 9/11 clusters showed 578-11,429 differentially expressed genes. In IG, MM had decreased expression of tissue-protective and microglial …

BACKGROUND: Although the associations between genetic variations and lung cancer risk have been explored, the epigenetic consequences of DNA methylation in lung cancer development are largely unknown. Here, the genetically predicted DNA methylation markers associated with non-small cell lung cancer (NSCLC) risk by a two-stage case-control design were investigated.

METHODS: The genetic prediction models for methylation levels based on genetic and methylation data of 1595 subjects from the Framingham Heart Study were established. The prediction models were applied to a fixed-effect meta-analysis of screening data sets with 27,120 NSCLC cases and 27,355 controls to identify the methylation markers, which were …

Neuroscience And The Criminal Legal System: A Humanitarian Application Framework, Dorothy Hayes

DePaul Journal of Health Care Law

Advancements in neuroscience call our intuitive notion of free will into question—and by implication, invite a reassessment of the United States criminal legal system and its reliance on radical personal agency. In the backdrop of the evolving landscape of neuroscience and neurolaw is an inquiry: how do we appropriately and ethically incorporate advancements of these fields into law and policy? This paper pulls that question to the forefront, advocating for a humanitarian-forward framework to guide the process. The framework emphasizes the Daubert standard, addresses the “G2i” problem, and includes a balancing test to ensure the protection of neurorights. The paper …

The Relationship Between Stress Mindset And Burnout In College Athletes, Amber M. Shipherd, Creighton Avery, Sarah Gomez, Kelly B. Renner

Journal of Athlete Development and Experience

High levels of stress can result in college athletes experiencing symptoms of burnout, and electing to terminate their sport participation. Research suggests there may be a relationship between athlete burnout and one’s view of stress (Avery et al., 2022). The purpose of this study was to examine the relationship between stress mindset and burnout in college athletes, while controlling for gender, coping self-efficacy, and perceived stress. College athletes (N = 118) completed measures of stress mindset, athletic burnout, coping self-efficacy, and perceived stress via online survey software. Non-parametric partial correlations were conducted to determine relationships between variables while controlling …

“Zero Preparation For Life After Sports”: Former College Athletes’ Use Of Tiktok To Express Transitioning Out Of Sport, Molly Harry, Sydney Hammit

Journal of Athlete Development and Experience

Every college athlete will transition out of competition and this transition is often tumultuous for athletes who have dedicated years to the sports they love. Despite these challenges, athletes are rarely given a platform to discuss their transition with peers experiencing a similar situation who can offer support. However, through social media, former college athletes are creating platforms to center their transition successes and struggles. Through the lens of Schlossberg’s Transition Theory (1981), this study used thematic analysis to examine transition experiences of former college athletes responding to a viral TikTok video. Comments (n = 869) demonstrated former athletes …

Dissecting The Genetic Diversity Of Usda Cowpea Germplasm Collection Using Kompetitive Allele Specific Pcr-Single Nucleotide Polymorphism Markers, Jesse Potts, Vincent N. Michael, Geoffrey Meru, Matthew W. Blair

Agricultural and Environmental Sciences Faculty Research

Cowpea (Vigna unguiculata L. Walp) is an important grain legume crop of the subtropics, particularly in West Africa, where it contributes to the livelihoods of small-scale farmers. Despite being a drought-resilient crop, cowpea production is hampered by insect pests, diseases, parasitic weeds, and various abiotic stresses. Genetic improvement can help overcome these limitations, and exploring diverse cowpea genetic resources is crucial for cowpea breeding. This study evaluated the genetic diversity of 361 cowpea accessions from the USDA core collection for the species using 102 Kompetitive Allele Specific PCR (KASP) single nucleotide polymorphism (SNP) markers. A total of 102 KASP-SNP was …

Leaving Home: Loss And Restoration In Marilynne Robinson's "Gilead" And "Housekeeping", Zachary Stevenson

Undergraduate Honors Theses

The concepts of restoration and reconciliation are central to Marilynne Robinson’s first two novels, Housekeeping (1980) and Gilead (2004). Housekeeping structures itself around the narrator Ruth Stone’s thirst for familial wholeness, and Gilead tracks the aging Congregationalist minister John Ames’s growing realization that there are rifts in both his town and his personal life that demand healing. The books are also united in their ambivalence towards the possibility of achieving total wholeness, as in each novel the movement towards restoration is undercut in important ways. However, the books ultimately diverge in the scope of the restitution that they allow. Whereas …

The Polyglutamine Domain Is The Primary Driver Of Seeding In Huntingtin Aggregation, Adam Skeens, Chathuranga Siriwardhana, Sophia E. Massinople, Michelle M. Wunder, Zachary L. Ellis, Kaitlyn M. Keith, Tyler Girman, Shelli L. Frey, Justin Legleiter

Chemistry Faculty Publications

Huntington’s Disease (HD) is a fatal, neurodegenerative disease caused by aggregation of the huntingtin protein (htt) with an expanded polyglutamine (polyQ) domain into amyloid fibrils. Htt aggregation is modified by flanking sequences surrounding the polyQ domain as well as the binding of htt to lipid membranes. Upon fibrillization, htt fibrils are able to template the aggregation of monomers into fibrils in a phenomenon known as seeding, and this process appears to play a critical role in cell-to-cell spread of HD. Here, exposure of C. elegans expressing a nonpathogenic N-terminal htt fragment (15-repeat glutamine residues) to preformed htt-exon1 fibrils induced …

The Effect Of Ethanol Treatment On The Protein Content Of Difi Exosomes, Kenzie Rushing

[Archive] Belmont University Research Symposium (BURS)

Colorectal cancer (CRC) is the second most common cause of cancer death in the United States in both men and women combined, second only to lung cancer.1 CRC metastasis is the primary cause of mortality largely due to therapy resistant cancer cells.2 Therefore, detection before metastasis is of great importance and could potentially lead to earlier detection and decreased mortality. Extracellular vesicles (EVs), including exosomes, are lipid bound vesicles secreted by cells3 that are involved in cell-cell communication and have been found to promote CRC progression and metastasis.4 The proteome of exosomes is thought to reflect that of the originating …

Herein, titanium dioxide (TiO2) NPs were bioengineered using a novel and facile ultrasound-assisted approach utilizing the greenly extracted essential oil of Ocimum basilicum. FTIR and UV-Vis spectrophotometry were used to confirm the formation of TiO2 NPs. The X-ray diffraction (XRD) analysis showed the crystalline nature of TiO2 NPs. TEM analysis revealed the spherical morphology of the NPs with sizes ranging from 5.55 to 13.89 nm. Energy-dispersive X-ray (EDX) confirmed the purity of the …

Neuroplasticity In The Dentate Gyrus: A Multimethod Investigation On Hippocampal Ltp Following Prenatal Alcohol Exposure, Monica Goncalves-Garcia

Psychology ETDs

Studies have demonstrated alcohol-related deficits in LTP associated with histaminergic and glutamatergic impairments. The histaminergic H3R inverse agonist ABT-239 has shown promise in reversing these deficits. The present study focuses on another H3R inverse agonist, SAR-152594, and its impact on LTP deficits following moderate PAE. The findings reveal that systemic administration of 1 mg/kg of SAR-152594 reverses deficits in potentiation fEPSPs in adult male rats exposed to moderate PAE. Time-frequency analyses of evoked responses indicate PAE-related reductions in power during the fEPSP and increased power during later components of evoked responses, both reversed by SAR-152594. These results provide further evidence …

Decolonizing And Diversifying The Biosciences Curriculum – A Practical Guide To Getting Started, Catherine Mansfield, Lovleen Tina Joshi, Isaiah J. Ting, Katharine Hubbard

Peninsula Dental School

To create inclusive bioscience learning environments, we need to challenge the dominance of white European perspectives within our discipline through diversification and decolonization of the curriculum. Bioscientists may be unsure how to start this process or may struggle to see how it is relevant within scientific disciplines. Here, we provide some practical suggestions of how to start with diversification and decolonization. We highlight a published culturally competent curriculum structure that may be of value and give multiple steps towards decolonization. These range from considering terminology, addressing gaps in our own knowledge to learning how to pronounce names from multiple cultures …

Why We Need To Decolonize The Biosciences Curriculum, Lovleen Tina Joshi, Catherine Mansfield, Isaiah J. Ting, Katharine Hubbard

Peninsula Dental School

Bioscience has a history linked to exploitation, colonialism and marginalization. Biology has been dominated by white European perspectives, and pseudoscientific ‘biological’ arguments have been used to justify discrimination and oppression, particularly on the basis of disability and ethnicity. Addressing this legacy within bioscience education is challenging, particularly as many bioscientists are unaware of this history and its on- going influence on the discipline. In this article, we explore what decolonization of the curriculum means within the context of bioscience. To demystify terminology for those new to the subject, we first consider the differences between diversification and decolonization. We then explore …

Quality Improvement Protocol: Improving The Use Of Nonpharmacological Pain Management Strategies Within The Inpatient Hospital Setting, Katherine Salamon, Christina Russell, Dara Devinney, Catherine M Soprano

Department of Medicine Faculty Papers

Background: There are many nonpharmacological pain management services available to hospitalized youth; however, not all youth are offered these services. Lack of knowledge about resources, difficulty with the referral process, and lack of understanding about nonpharmacological pain management services and when to refer patients are among the main reasons for lack of utilization. Quality improvement (QI) initiatives have grown within hospital settings and can serve to create change in fast-paced environments. Methods: The current QI project aimed to pilot an educational program to increase the use of nonpharmacological pain management interventions. Staff located on one floor of a pediatric hospital …
