Whole Exome Sequencing As A Screening Tool In Dogs: A Pilot Study, Fréderique Boeykens, Evelien Bogaerts, Liesbeth Vossaert, Luc Peelman, Filip Van Nieuwerburgh, Jimmy H Saunders, Bart J G Broeckx

Faculty, Staff and Students Publications

Background: Whole-exome sequencing (WES) is used to selectively sequence all exons of protein-coding genes. WES is considered as a cost-effective and direct approach for identifying phenotype-associated variants in protein-coding regions and is as such situated between the traditional Sanger sequencing and whole genome sequencing (WGS). While WES is already widely used as a clinical tool in human and medical genetics, its use in veterinary medicine is currently restricted to research purposes. In this article, we aimed to provide baseline performance characteristics of a WES design to assess its suitability with future applications in veterinary clinical genetics in mind.

Despite the efficacy of approved severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in preventing severe disease and death, breakthrough infections continue to occur in vaccinated individuals, contributing to further viral mutation and spread. These limitations may be attributable to the poor induction of mucosal immunity by parenteral vaccination. Mucosal adjuvants, such as T-vant, can enhance vaccine-induced immune responses through the generation of antigen-specific antibodies and T cells in the respiratory tract. In this study, we evaluated the protective efficacy of adjuvanted SARS-CoV-2 receptor binding domain (RBD) subunit vaccines administered by homologous and heterologous routes. Immunized mice were challenged with …

Real-World Experiences With Vmat2 Inhibitors In Pediatric Hyperkinetic Movement Disorders, Sujal Manohar, Jennifer Jacobe, Rebecca Berger, Joseph Jankovic, Mariam Hull

Faculty, Staff and Students Publications

Background: Vesicular monoamine transporter 2 (VMAT2) inhibitors are often prescribed for the treatment of hyperkinetic movement disorders such as tics, stereotypy, tardive dyskinesia and chorea. These dopamine depleters have been FDA approved in adults for the treatment of chorea in Huntington's disease and tardive dyskinesia. Use of VMAT2 inhibitors in pediatric hyperkinetic movement disorders, however, is limited due to lack of pediatric FDA approval. We review the real-world prescribing practices and patient experiences with VMAT2 inhibitors in children.

Methods: We performed a retrospective chart review of patients treated with VMAT2 inhibitors at a pediatric movement disorders clinic from 2011 to …

Promotion Of Hiv Clearance By Sensitization Of Hiv Reservoirs To Cell Death, Min Li, Baichao Sun, Jing Dong, Jian-Rong Li, Laurie J Minze, Min Chen, Chao Cheng, Jin Wang

Faculty, Staff and Students Publications

Introduction: HIV integrates its proviral DNA into the host genome to establish persistent infection. To promote HIV clearance, we have designed an approach for selective elimination of host cells harboring replication-competent HIV (SECH), through inhibition of autophagy and anti-apoptotic molecules during viral reactivation. SECH approach can clear HIV-infected cells in approximately 50% humanized mice. However, the mechanisms for the resistance of reservoirs to depletion in mice with failure in HIV clearance are unclear.

Methods: We have performed single cell transcriptome analyses of HIV-infected T cells that escaped the treatments, in order to identify cellular pathways that could be targeted to …

Paternal Upd (15) With Disease-Causing Mutation And Small Supernumerary Ring Chromosome 15: A Case Report, David Lee Curtis, Nasim Bekheirnia, Lorraine Potocki, Ludmila Matyakhina, Mir Reza Bekheirnia

Faculty, Staff and Students Publications

Uniparental disomy (UPD) constitutes an unconventional mode of inheritance that disrupts the typical biparental genetic contribution and may result in phenotypic abnormalities. This report centers on a patient diagnosed with Bartter syndrome Type 1, attributed to a homozygous pathogenic variant in SLC12A1 unmasked by mosaic paternal UPD of chromosome 15. We hypothesize that this pattern (or constellation) emerged from a trisomy rescue event, resulting in two distinct cell lines. Concurrently, the unmasking of a pathogenic paternal SLC12A1 variant by trisomy rescue resulted in the manifestation of Bartter syndrome Type 1. The maternally derived ring chromosome 15 and its impact on …

Developing An Annual Review Of The Literature, Weinstein R Amy, Szauter Karen, Duca Nicholas, Jacob Jackcy, Ismail Nadia, Pincavage Amber, Walsh Katherine, Alexandraki Irene

Faculty, Staff and Students Publications

Many national meetings and speaker series feature an "Annual Review of the Literature" (ARL) session in which an individual or team presents a sampling of articles, selected and prepared because they represent important current topics or new ideas in the discipline of interest. Despite this, there is little in the medical literature describing how to thoughtfully and systematically develop these sessions. We identify best practices that we have developed and used in the United States Clerkship Directors of Internal Medicine (CDIM) over many years. These include identification of a theme, team assembly, timeline development, search strategy and rubric development and …

The skills needed to collaboratively solve a jigsaw puzzle illustrate the key concepts of computational thinking in a straightforward way that makes the basics of decomposition, pattern recognition, abstraction, and algorithmic thinking come to life. The learning representation included here was taught as part of a professional development workshop for PK-12 teachers but could easily be adapted to use with learners from upper elementary grades through middle school, high school, or university.

Modeling Functional Connectivity With Learning And Memory In A Mouse Model Of Alzheimer’S Disease, Lindsay Fadel, Elizabeth Hipskind, Steen E Pedersen, Jonathan Romero, Caitlyn Ortiz, Eric Shin, Md Abul Hassan Samee, Robia G Pautler

Faculty, Staff and Students Publications

Introduction: Functional connectivity (FC) is a metric of how different brain regions interact with each other. Although there have been some studies correlating learning and memory with FC, there have not yet been, to date, studies that use machine learning (ML) to explain how FC changes can be used to explain behavior not only in healthy mice, but also in mouse models of Alzheimer's Disease (AD). Here, we investigated changes in FC and their relationship to learning and memory in a mouse model of AD across disease progression.

Methods: We assessed the APP/PS1 mouse model of AD and wild-type controls …

An Analytical Review Of Preprocessing Techniques In Bengali Natural Language Processing, Sovon Chakraborty, Protiva Das, Shakib Mahmud Dipto, Md Aktaruzzaman Pramanik, Jannatun Noor

Computer Science Faculty Publications

Research in Bengali Natural Language Processing (BNLP) is rapidly expanding. Despite being one of the most widely spoken languages in the world, BNLP research remains insufficient, particularly in Bengali speech recognition. The languages rich morphology, agglutinative structure, and diverse dialects make text and speech processing especially challenging. However, these challenges can be addressed with effective preprocessing techniques. Various organizations in Bangladesh and West Bengal are integrating Natural Language Processing (NLP) into their services, but without a thorough understanding of preprocessing, these implementations remain incomplete. Applying proper preprocessing techniques to the Bengali language will serve as a foundation for developing robust …

Igf-1 Impacts Neocortical Interneuron Connectivity In Epileptic Spasm Generation And Resolution, Carlos J Ballester-Rosado, John T Le, Trang T Lam, Anne E Anderson, James D Frost, John W Swann

Faculty, Staff and Students Publications

Little is known about the mechanisms that generate epileptic spasms following perinatal brain injury. Recent studies have implicated reduced levels of Insulin-like Growth Factor 1 (IGF-1) in these patients' brains. Other studies have reported low levels of the inhibitory neurotransmitter, GABA. In the TTX brain injury model of epileptic spasms, we undertook experiments to evaluate the impact of IGF-1 deficiencies on neocortical interneurons and their role in spasms. Quantitative immunohistochemical analyses revealed that neocortical interneurons that express glutamic acid decarboxylase, parvalbumin, or synaptotagmin 2 co-express IGF-1. In epileptic rats, expression of these three interneuron markers were reduced in the neocortex. …

Analysis Of 1,25-Dihydroxyvitamin D Genomic Action In Human Enteroids And Colonoids Reveals Multiple Regulatory Effects Of Vitamin D In Human Intestinal Physiology, Zachary K Criss, Kali Deans-Fielder, James C Fleet, Sylvia Christakos, Noah Shroyer

Faculty, Staff and Students Publications

Introduction: The intestine has molecular and functional diversity across the proximal-distal and the crypt-villus axes, so it is imperative to determine the common and compartment-specific molecular actions of vitamin D. However, very little work on vitamin D mediated gene regulation has been done in normal human intestine. Here, we examined the impact of 1,25-dihydroxyvitamin D (1,25(OH)2D3) on cultures of human intestinal epithelium derived from duodenum (Dd) and distal colon (Co) biopsies of 6 subjects per tissue.

Methods: Human enteroids and colonoids were cultured for 3 days to promote a stem cell phenotype (undifferentiated, Un) or to induce differentiation (Diff) and …

Faculty, Staff and Students Publications

BACKGROUND: Vertebral body defects pose a significant challenge in spinal reconstructive surgery. Compression fractures of the vertebral corpus are typically treated with vertebral augmentation procedures. There are significant risks associated with the introduction of foreign material in the spine, including infection and pseudarthrosis. Vascularized bone grafts (VBGs) have become a popular alternative for spinal reconstruction in the last decade thanks to their robust blood supply and autologous nature. VBGs have been described predominantly for the reconstruction of posterior vertebral defects. The objective of this study is to describe a novel procedure for the reconstruction of vertebral corpus defects in the …

Faculty, Staff and Students Publications

According to the ESC guidelines, cangrelor may be considered in P2Y12-inhibitor-naïve acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI). The aim of this review is to summarize available evidence on the optimal maintenance therapy with P2Y12 receptor inhibitor after cangrelor. Transitioning from cangrelor to a thienopyridine, but not ticagrelor, can be associated with a drug-drug interaction (DDI); therefore, a ticagrelor loading dose (LD) can be given any time before, during, or at the end of a cangrelor infusion, while a LD of clopidogrel or prasugrel should be administered at the time the infusion of cangrelor ends or within …

The Great Scrape: The Clash Between Scraping And Privacy, Daniel J. Solove, Woodrow Hartzog

Faculty Scholarship

Artificial intelligence (AI) systems depend on massive quantities of data, often gathered by “scraping”—the automated extraction of large amounts of data from the internet. A great deal of scraped data contains people’s personal information. This personal data provides the grist for AI tools such as facial recognition, deep fakes, and generative AI. Although scraping enables web searching, archiving of records, and meaningful scientific research, scraping for AI can also be objectionable and even harmful to individuals and society.

Organizations are scraping at an escalating pace and scale, even though many privacy laws are seemingly incongruous with the practice. In this …

How Theories Of Art Can Inform Debates About Ai, Jessica Silbey

Faculty Scholarship

Debates about artificial intelligence (AI) tend to swing between the optimistic and the apocalyptic. I propose a less binary approach that frames conversations about AI from the perspectives of theories of art and creativity. Whether we agree that AI is artificial or intelligent, whether it should be constrained or liberated, we cannot deny its influence on literary, artistic, and innovative production. AI may be described as simply a new tool to produce art and science, like the camera or the microscope, or it may transform art and science, the way the internet transformed global communication. Either way, these debates about …

Foundations For Platform Liability, Kathryn E. Spier, Rory Van Loo

Faculty Scholarship

From spreading misinformation to selling deadly products, bad actors use technology platforms to their advantage while causing devastating harms to privacy, health, and even democracy. Despite their central role in enabling these bad actors, the platforms almost entirely escape liability. This legal immunity is purportedly grounded in economics. From the beginning, courts and legislatures feared that liability would chill innovation, growth, and user access. They also speculated that platforms have sufficient market incentives to voluntarily police bad actors, making liability unnecessary.

Whereas many scholars have argued that platform immunity is blind to justice, this Article shows that it is also …

We measure the spin-density matrix elements (SDMEs) for the photoproduction of 𝜙⁡(1020) off of the proton in its decay to 𝐾⁰_𝑆⁢𝐾⁰_𝐿, using 105 pb⁻¹ of data collected with a linearly polarized photon beam using the GlueX experiment. The SDMEs are measured in nine bins of the squared four-momentum transfer 𝑡 in the range −𝑡=0.15−1.0 GeV², providing the first measurement of their 𝑡 dependence for photon beam energies of 𝐸𝛾=8.2−8.8 GeV. We confirm the dominance of Pomeron exchange in this region and put constraints on the contribution of other Regge exchanges. We also …

Small-X Gluon Gpd Constrained From Deeply Virtual J/Ψ Production And Gluon Pdf Through Universal-Moment Parametrization, Yuxun Guo, Xiangdong Ji, M. Gabriel Santiago, Jinghong Yang, Hao-Cheng Zhang

Physics Faculty Publications

We phenomenologically constrain the small-x and small-𝜉 gluon generalized parton distributions (GPDs) with the deeply virtual J/ψ production (DVJ/ψP) in the framework of GPDs through universal moment parameterization (GUMP). We use a hybrid cross-section formula combining collinear factorization to the next-to-leading order (NLO) accuracy of the strong coupling 𝛼_s, with corrections from nonrelativistic QCD to account for the power corrections due to the heavy J/ψ mass. We reach reasonable fit to the measured differential cross sections of DVJ/ψP by H1 at the Hadron-Electron Ring Accelerator as well as forward gluon parton distribution functions (PDFs) from JAM22 global analysis. …
