The Ventral Hippocampus Dynamically Regulates Amygdala Encoding And Learned Fear, Matthew Richard Herbst

Dissertations (1934 -)

The nervous system has evolved a set of survival circuits optimized to respond to environmental threats. Adaptive threat responding requires learning to predict when and where a threat may occur based on available cues. Such learning depends on a distributed network of brain structures, but there is much we do not understand about how these brain areas interact to support fear memory. Addressing this gap is crucial for understanding anxiety- and fear-related disorders as dysfunction in fear learning networks is implicated in the development and persistence of pathological fear states. In my dissertation work, I used a rodent model of …

Predicting Mental Health Crisis In Veterans: Early Warning Signs, Precursors And Protective Factors, Priyanka Annapureddy

Dissertations (1934 -)

Mental Health (MH) conditions have recently increased to a large extent due to socio-demographic changes. Posttraumatic Stress Disorder (PTSD) is one of the most common mental health disorders prevalent in US. PTSD is even more troubling at double the rate in combat veterans leaving their service compared to general population. Severity of PTSD is associated with risk taking behaviors such as substance abuse, non-suicidal self-injury, and sexual risk behaviors. Psychological disorders are often preceded by early warning signs and recognizing the early warning signs of PTSD will help in preventing the returning or worsening of PTSD symptoms. Ecological momentary assessment …

Investigations Into The Negative Impact Of Temperature Stress On Fertility In Wild Strains Of Caenorhabditis Elegans, Nicholas B. Sepulveda

Dissertations (1934 -)

Sexual reproduction and its coincident genetic recombination are powerful adaptive strategies. However, sexual reproduction has disadvantages. One ancient and conserved disadvantage is temperature sensitivity. In organisms diverse as plants, insects, nematode worms, and humans, as temperatures increase, fertility decreases. The goal of this dissertation is to examine the negative impact of elevated temperature stress on fertility in sexually reproducing organisms using wild strains of Caenorhabditis elegans. C. elegans presents a unique opportunity to study these effects broadly in two contexts, as worms may be either self-fertile hermaphrodites that produce both egg and sperm or males which produce only sperm. In …

Remembering Who Foster Care Is For: Public Accommodation And Other Misconceptions And Missed Opportunities In Fulton V. City Of Philadelphia, Chris Gottlieb

Cardozo Law Review

The Supreme Court’s opinion in Fulton v. City of Philadelphia, which held that a Catholic foster care agency could refuse to accept gay foster parents, and virtually all commentary on the case, are flawed by a profound misunderstanding of key aspects of the foster care system. The case’s role in the broader culture war between religious rights advocates and those supporting LGBTQ equality has led advocates on both sides to use Fulton for their own purposes at the expense of the families the foster care system is intended to serve.

Carrie Menkel-Meadow: Dispute Resolution In A Feminist Voice, Andrea K. Schneider

Articles

The presence of women in the law has changed the law’s substance, practice, and process. Carrie Menkel-Meadow, whose scholarship centers on this theme, is one such revolutionary woman.

Professor Menkel-Meadow, who I am proud to call my colleague, co-author, and friend (hereinafter referred to as Carrie), began her career in 1977 with a series of simple questions that sparked a breathtaking body of work. Carrie probed the depth of male domination in the realm of law and wondered what changes female representation might engender. In particular, she focused her inquiry on the value orientation each respective gender might bring to …

Latinas’ Use Of Spirituality As A Coping Mechanism, Ashley Lauren Faytol

Dissertations (1934 -)

Intimate partner violence (IPV) is a widespread public health concern with consequences that negatively impact many areas of survivors’ functioning (Centers for Disease Control and Prevention [CDC], 2017, 2019; Ellsberg et al., 2008; Gorde et al., 2004; Kelly, 2010a). The negative impacts of IPV are more severe for Latinas than their White counterparts (e.g., Bonomi et al., 2009; Kelly, 2010b; Stockman et al., 2015), causing IPV to be considered a health disparity within the Latina community (Caetano et al., 2005). While spirituality has been shown to be an effective coping mechanism for many stressors in Latinas’ lives, it has not …

Transdisciplinarity In Transformative Ocean Governance Research - Reflections Of Early Career Researchers, Mia Strand, Kelly Ortega-Cisneros, Holly J. Niner, Michel Wahome, James Bell, Jock C. Currie, Hashali Hamukuaya, Giulia La Bianca, Alana M.S.N. Lancaster, Ntemesha Maseka, Lisa Mcdonald, Kirsty Mcquaid, Marly M. Samuel, Alexander Winkler

School of Biological and Marine Sciences

This paper interrogates the concept of transdisciplinarity, both theoretically and practically, from a perspective of early career researchers (ECRs) in transformative ocean governance research. Aiming to advance research methodologies for future complex sustainability challenges, the paper seeks to illuminate some common uncertainties and challenges surrounding transdisciplinarity from a marine science perspective. Following a literature review on transdisciplinary research, workshops, and a series of surveys, we determine that transdisciplinarity appears to be a concept in search of definition, and that there is a need to explore transdisciplinarity specifically from an ocean research perspective. The paper discusses a number of challenges experienced …

Dietary Inorganic Nitrate As An Ergogenic Aid: An Expert Consensus Derived Via The Modified Delphi Technique, Oliver M. Shannon, Jason D. Allen, Raul Bescos, Louise Burke, Tom Clifford, Chris Easton, Javier T. Gonzalez, Andrew M. Jones, Kristin L. Jonvik, Filip J. Larsen, Peter Peeling, Barbora Piknova, Mario Siervo, Anni Vanhatalo, Kerry Mcgawley, Simone Porcelli

School of Health Professions

Abstract Introduction Dietary inorganic nitrate is a popular nutritional supplement, which increases nitric oxide bioavailability and may improve exercise performance. Despite over a decade of research into the effects of dietary nitrate supplementation during exercise there is currently no expert consensus on how, when and for whom this compound could be recommended as an ergogenic aid. Moreover, there is no consensus on the safe administration of dietary nitrate as an ergogenic aid. This study aimed to address these research gaps. Methods The modified Delphi technique was used to establish the views of 12 expert panel members on the use of …

Symptom Severity Mixity In Older-Age Bipolar Disorder: Analyses From The Global Aging And Geriatric Experiments In Bipolar Disorder Database (Gage-Bd), Farren B.S. Briggs, Martha Sajatovic

Faculty Scholarship

Objective: Some individuals with bipolar disorder (BD) experience manic and depressive symptoms concurrently, but data are limited on symptom mixity in older age bipolar disorder (OABD). Using the Global Aging & Geriatric Experiments in Bipolar Disorder Database, we characterized mixity in OABD and associations with everyday function. Methods: The sample (n = 805), from 12 international studies, included cases with both mania and depression severity ratings at a single timepoint. Four mixity groups were created: asymptomatic (A), mixed (Mix), depressed only (Dep), and manic only (Man). Generalized linear mixed models used mixity group as the predictor variable; cohort was included …

Recommendations For Establishing A Market For Invasive Green Crabs In New England, Eve Fischer, Jesse Minor, Marissa Mcmahan

All Faculty Scholarship

Green crabs are one of the most invasive marine species in the world. Their populations in New England have grown significantly due to climate change, increasing their environmental and socioeconomic impacts. Green crabs are voracious predators of soft shell clams, and have had a detrimental impact on the region’s valuable clam fisheries. They also prey on juvenile lobsters and other shellfish and compete with native crab species for resources. Green crabs burrow into and damage eelgrass beds, which are a vital habitat for many marine species and an important “blue carbon” sink. Due to their rapid rate of reproduction as …

Redefining The Catalytic Hect Domain Boundaries For The Hect E3 Ubiquitin Ligase Family, Emma I. Kane, Steven A. Beasley, Johanna M. Schafer, Justine E. Bohl, Young Sun Lee, Kayla J. Rich, Elizabeth F. Bosia, Donald E. Spratt

Chemistry

There are 28 unique human members of the homologous to E6AP C-terminus (HECT) E3 ubiquitin ligase family. Each member of the HECT E3 ubiquitin ligases contains a conserved bilobal HECT domain of approximately 350 residues found near their C-termini that is responsible for their respective ubiquitylation activities. Recent studies have begun to elucidate specific roles that each HECT E3 ubiquitin ligase has in various cancers, age-induced neurodegeneration, and neurological disorders. New structural models have been recently released for some of the HECT E3 ubiquitin ligases, but many HECT domain structures have yet to be examined due to chronic insolubility and/or …

The Trichloroethylene Metabolite S-(1,2-Dichlorovinyl)-L-Cysteine Inhibits Lipopolysaccharide-Induced Inflammation Transcriptomic Pathways And Cytokine Secretion In A Macrophage Cell Model, Sean M. Harris, Kelly M. Bakulski, John Dou, Ethan Houskamp, Eleanor Scheeres, Emily Schellenboom, Olivia Harlow, Rita Loch-Caruso, Erica Boldenow

University Faculty Publications and Creative Works

Studies have shown that the trichloroethylene metabolite S-(1,2-dichlorovinyl)-l-cysteine (DCVC) inhibits cytokine secretion in pathogen stimulated fetal membrane tissue but little is known about the mechanism for these effects, including which cell types or transcriptomic pathways are impacted. Macrophages play a critical role in fetal membrane immune responses during infection. We tested the hypothesis that DCVC inhibits lipopolysaccharide (LPS) stimulated inflammation pathways in macrophage-like THP-1 cells. We treated THP-1 cells for 24 h then treated with 1, 5, or 10 μM DCVC for 24 h. After a 4 h incubation with lipopolysaccharide (LPS), we collected RNA and cell media. We performed …

Beginning with the development of the first social work competencies (labeled Abilities), pioneering efforts in assessment and holistic curricular design and delivery are reviewed. A new, one-semester, social work generalist curriculum is introduced. Emphasis is placed on the importance of developing a competency-based curriculum that is integrated both horizontally and vertically and that engages the social work student …

Incidence And 5-Year Survival Of Children And Adolescents With Hepatoblastoma In The United States, Justin A Kahla, David A Siegel, Shifan Dai, Philip J Lupo, Jennifer H Foster, Michael E Scheurer, Andras A Heczey

Center for Medical Ethics and Health Policy Staff Publications

Objective: Hepatoblastoma (HB) is the most common pediatric primary malignant liver tumor, its incidence has been increasing worldwide, but recent changes in incidence and outcomes with high population coverage are not well characterized.

Methods: We defined the incidence of HB diagnosed during 2003-2017 from United States Cancer Statistics (USCS) database, and survival during 2001-2016 from the National Program of Cancer Registries (NPCR). Data were stratified by sex, race/ethnicity, age, tumor stage, county population, and diagnosis year. Incidence trends were assessed by calculating average annual percent change (AAPC) using Joinpoint regression. Differences in overall 5-year survival were estimated using Cox regression …

Psychiatric Polygenic Risk Scores: Child And Adolescent Psychiatrists’ Knowledge, Attitudes, And Experiences, Stacey Pereira, Katrina A Muñoz, Brent J Small, Takahiro Soda, Laura N Torgerson, Clarissa E Sanchez, Jehannine Austin, Eric A Storch, Gabriel Lázaro-Muñoz

Center for Medical Ethics and Health Policy Staff Publications

Psychiatric polygenic risk scores (PRS) have potential utility in psychiatric care and prevention, but there are concerns about their implementation. We surveyed 960 US-based practicing child and adolescent psychiatrists' (CAP) about their experiences, perspectives, and potential uses of psychiatric PRS. While 23% of CAP reported that they had never heard of PRS, 10 % of respondents have had a patient/family bring PRS to them and 4% have generated PRS for patients. Though 25% stated they would request PRS if a patient/caregiver asked, 35% indicated that nothing would prompt them to request PRS. Most respondents (54%) believed psychiatric PRS are currently …

Potential Interactions Between Cerebellar Dysfunction And Sleep Disturbances In Dystonia, Luis E Salazar Leon, Roy V Sillitoe

Duncan NRI Faculty and Staff Publications

Dystonia is the third most common movement disorder. It causes debilitating twisting postures that are accompanied by repetitive and sometimes intermittent co- or over-contractions of agonist and antagonist muscles. Historically diagnosed as a basal ganglia disorder, dystonia is increasingly considered a network disorder involving various brain regions including the cerebellum. In certain etiologies of dystonia, aberrant motor activity is generated in the cerebellum and the abnormal signals then propagate through a "dystonia circuit" that includes the thalamus, basal ganglia, and cerebral cortex. Importantly, it has been reported that non-motor defects can accompany the motor symptoms; while their severity is not …

Identifying Phenotypic Expansions For Congenital Diaphragmatic Hernia Plus (Cdh+) Using Decipher Data, Amy Hardcastle, Aliska M Berry, Ian M Campbell, Xiaonan Zhao, Pengfei Liu, Amanda E Gerard, Jill A Rosenfeld, Saumya D Sisoudiya, Andres Hernandez-Garcia, Sara Loddo, Silvia Di Tommaso, Antonio Novelli, Maria L Dentici, Rossella Capolino, Maria C Digilio, Ludovico Graziani, Cecilie F Rustad, Katherine Neas, Giovanni B Ferrero, Alfredo Brusco, Eleonora Di Gregorio, Diana Wellesley, Claire Beneteau, Madeleine Joubert, Kris Van Den Bogaert, Anneleen Boogaerts, Dominic J Mcmullan, John Dean, Maria G Giuffrida, Laura Bernardini, Vinod Varghese, Nora L Shannon, Rachel E Harrison, Wayne W K Lam, Shane Mckee, Peter D Turnpenny, Trevor Cole, Jenny Morton, Jacqueline Eason, Marilyn C Jones, Rebecca Hall, Michael Wright, Karen Horridge, Chad A Shaw, Wendy K Chung, Daryl A Scott

Congenital diaphragmatic hernia (CDH) can occur in isolation or in conjunction with other birth defects (CDH+). A molecular etiology can only be identified in a subset of CDH cases. This is due, in part, to an incomplete understanding of the genes that contribute to diaphragm development. Here, we used clinical and molecular data from 36 individuals with CDH+ who are cataloged in the DECIPHER database to identify genes that may play a role in diaphragm development and to discover new phenotypic expansions. Among this group, we identified individuals who carried putatively deleterious sequence or copy number variants affecting CREBBP, SMARCA4, …

Residence In A Latinx Enclave And End-Induction Minimal Residual Disease Positivity Among Children With Acute Lymphoblastic Leukemia, Joshua P Muñiz, John P Woodhouse, Amy E Hughes, Sandi L Pruitt, Karen R Rabin, Michael E Scheurer, Philip J Lupo, Jeremy M Schraw

Center for Medical Ethics and Health Policy Staff Publications

Racial and ethnic inequities in survival persist for children with acute lymphoblastic leukemia (ALL). In the US, there are strong associations between SES, race/ethnicity, and place of residence. This is evidenced by ethnic enclaves: neighborhoods with high concentrations of ethnic residents, immigrants, and language isolation. The Latinx enclave index (LEI) can be used to investigate how residence in a Latinx enclave is associated with health outcomes. We studied the association between LEI score and minimal residual disease (MRD) in 142 pediatric ALL patients treated at Texas Children's Hospital. LEI score was associated with end-induction MRD positivity (OR per unit increase …

Center for Medical Ethics and Health Policy Staff Publications

Post-transplantation cyclophosphamide (PTCy) has been shown to effectively control graft-versus-host disease (GvHD) in haploidentical (Haplo) transplantations. In this retrospective registry study, we compared GvHD organ distribution, severity, and outcomes in patients with GvHD occurring after Haplo transplantation with PTCy GvHD prophylaxis (Haplo/PTCy) versus HLA-matched unrelated donor transplantation with conventional prophylaxis (MUD/conventional). We evaluated 2 cohorts: patients with grade 2 to 4 acute GvHD (aGvHD) including 264 and 1163 recipients of Haplo and MUD transplants; and patients with any chronic GvHD (cGvHD) including 206 and 1018 recipients of Haplo and MUD transplants, respectively. In comparison with MUD/conventional transplantation ± antithymocyte globulin …

Telomere Biology Disorders: Time For Moving Towards The Clinic?, Luis F Z Batista, Inderjeet Dokal, Roy Parker

2020-Current year OA Pubs

Telomere biology disorders (TBDs) are a group of rare diseases caused by mutations that impair telomere maintenance. Mutations that cause reduced levels of TERC/hTR, the telomerase RNA component, are found in most TBD patients and include loss-of-function mutations in hTR itself, in hTR-binding proteins [NOP10, NHP2, NAF1, ZCCHC8, and dyskerin (DKC1)], and in proteins required for hTR processing (PARN). These patients show diverse clinical presentations that most commonly include bone marrow failure (BMF)/aplastic anemia (AA), pulmonary fibrosis, and liver cirrhosis. There are no curative therapies for TBD patients. An understanding of hTR biogenesis, maturation, and degradation has identified pathways and …

Functional Characterization Of Enhancer Activity During A Long Terminal Repeat's Evolution, Alan Y Du, Xiaoyu Zhuo, Vasavi Sundaram, Nicholas O Jensen, Hemangi G Chaudhari, Nancy L Saccone, Barak A Cohen, Ting Wang

2020-Current year OA Pubs

Many transposable elements (TEs) contain transcription factor binding sites and are implicated as potential regulatory elements. However, TEs are rarely functionally tested for regulatory activity, which in turn limits our understanding of how TE regulatory activity has evolved. We systematically tested the human LTR18A subfamily for regulatory activity using massively parallel reporter assay (MPRA) and found AP-1- and CEBP-related binding motifs as drivers of enhancer activity. Functional analysis of evolutionarily reconstructed ancestral sequences revealed that LTR18A elements have generally lost regulatory activity over time through sequence changes, with the largest effects occurring owing to mutations in the AP-1 and CEBP …

Neoadjuvant Atezolizumab For Resectable Non-Small Cell Lung Cancer: An Open-Label, Single-Arm Phase Ii Trial, Jamie E Chaft, G Alexander Patterson, Saiama N Waqar, Et Al.

2020-Current year OA Pubs

In an ongoing, open-label, single-arm phase II study ( NCT02927301 ), 181 patients with untreated, resectable, stage IB-IIIB non-small cell lung cancer received two doses of neoadjuvant atezolizumab monotherapy. The primary end point was major pathological response (MPR; ≤10% viable malignant cells) in resected tumors without EGFR or ALK alterations. Of the 143 patients in the primary end point analysis, the MPR was 20% (95% confidence interval, 14-28%). With a minimum duration of follow-up of 3 years, the 3-year survival rate of 80% was encouraging. The most common adverse events during the neoadjuvant phase were fatigue (39%, 71 of 181) …

Physical Adversarial Attack On A Robotic Arm, Yifan Jia, Christopher M. Poskitt, Jun Sun, Sudipta Chattopadhyay

Research Collection School Of Computing and Information Systems

Collaborative Robots (cobots) are regarded as highly safety-critical cyber-physical systems (CPSs) owing to their close physical interactions with humans. In settings such as smart factories, they are frequently augmented with AI. For example, in order to move materials, cobots utilize object detectors based on deep learning models. Deep learning, however, has been demonstrated as vulnerable to adversarial attacks: a minor change (noise) to benign input can fool the underlying neural networks and lead to a different result. While existing works have explored such attacks in the context of picture/object classification, less attention has been given to attacking neural networks used …

Immersion In Hot Water As A Phytosanitary Treatment For Thaumatotibia Leucotreta (Lepidoptera: Tortricidae) In Bell Pepper (Capsicum Annuum L.), Nelson L. Mwando, Shepard Ndlela, Rainer Meyhöfer, Sevgan Subramanian, Samira A. Mohamed

All Peer-Reviewed Publications

The False codling moth (FCM), Thaumatotibia leucotreta is a major quarantine pest that hampers Capsicum production and trade in sub-Saharan Africa (SSA) and may need a postharvest treatment to meet quarantine standards of lucrative overseas markets. In this study, we evaluated the efficacy of hot water treatment (HWT) as a potential nonchemical quarantine control option against T. leucotreta in bell pepper and its effect on the quality parameters of the peppers. Infested bell pepper harboring different immature stages of T. leucotreta were subjected to a hot water treatment of 50 ± 0.2 °C for eight different time-points to determine heat …
