To escape from dangerous stimuli, animals execute escape behaviors that are fundamentally different from normal locomotion. The rolling escape behavior of Drosophila larvae consists of C-shaped bending and rolling. However, the muscle contraction patterns that lead to rolling are poorly understood. We find that following the initial body bending, muscles contract in a circumferential wave around the larva as they enter the bend, maintaining unidirectional rolling that resembles a cylinder rolling on a surface. We study the structure of motor circuits for rolling, inhibit different motor neurons to determine which muscles are essential for rolling, and propose circuit and biomechanical …

BACKGROUND: The most prevalent cancer treatments cause cell death through DNA damage. However, DNA damage response (DDR) repair pathways, initiated by tumor cells, can withstand the effects of anticancer drugs, providing justification for combining DDR inhibitors with DNA-damaging anticancer treatments.

METHODS: Cell viability assays were performed with CellTiter-Glo assay. DNA damage was evaluated using Western blotting analysis. RNA-seq and single-cell level expression were used to identify the DDR signatures. In vivo, studies were conducted in mice to determine the effect of ATris on TMZ sensitization.

RESULTS: We found a subpopulation of glioma sphere-forming cells (GSCs) with substantial synergism with temozolomide …

Interleukin-17-Mediated Protective Cytokine Signaling Against Degeneration Of The Retinal Pigment Epithelium, Yan Chen, Sarah E Bounds, Xiang Ma, James Regun Karmoker, Yin Liu, Jian-Xing Ma, Jiyang Cai

Faculty, Staff and Student Publications

Injuries to the retinal pigment epithelium (RPE) and outer retina often result in the accumulation of retinal microglia within the subretinal space. These subretinal microglia play crucial roles in inflammation and resolution, but the mechanisms governing their functions are still largely unknown. Our previous research highlighted the protective functions of choroidal γδ T cells in response to RPE injury. In the current study, we employed single-cell RNA sequencing approach to characterize the profiles of immune cells in mouse choroid. We found that γδ T cells were the primary producer of interleukin-17 (IL-17) in the choroid. IL-17 signaled through its receptor …

Correlation Between Purposeful Patient Medication Education And Patient Experience Scores, Paula Shredl

Doctoral Dissertations and Projects

The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) is a national grading system that is used by payors to determine patients’ perception of their hospital stay. This public benchmarking system is tied to reimbursements and encompasses several domain areas. The medication and nursing domain questions revolve around how the nursing staff explained the purpose and possible side effects of patient medication. This project targeted a medical-surgical unit in a suburban faith-based hospital that was not meeting the national benchmarks in the nursing domain. The purpose of this evidence-based practice project, which was conducted using the Iowa Model of …

Using Mindfulness In Nursing Burnout. An Integrative Review., April Day Branham

Doctoral Dissertations and Projects

The purpose of this integrative review is to evaluate if mindfulness is effective in decreasing nursing burnout. Nursing burnout has negatively affected the nursing profession for many years, and since the COVID-19 pandemic, it appears to be worse. Mindfulness is a practice that has been used for decades, however, it is gaining more attention in the nursing realm. Mindfulness consists of being present in a moment without judgment. It can consist of individual exercises that are completed using an instructor in person, in an application on a smartphone or computer, or yoga-based mindful activities. A preliminary literature review was completed …

Multiple cancers exhibit aberrant protein arginine methylation by both type I arginine methyltransferases, predominately protein arginine methyltransferase 1 (PRMT1) and to a lesser extent PRMT4, and by type II PRMTs, predominately PRMT5. Here, we perform targeted proteomics following inhibition of PRMT1, PRMT4, and PRMT5 across 12 cancer cell lines. We find that inhibition of type I and II PRMTs suppresses phosphorylated and total ATR in cancer cells. Loss of ATR from PRMT inhibition results in defective DNA replication stress response activation, including from PARP inhibitors. Inhibition of type I and II PRMTs is synergistic with PARP inhibition regardless of homologous …

In this issue of the Journal of Bacteriology, N. J. Bonde, E. A. Wood, K. S. Myers, M. Place, J. L. Keck, and M. M. Cox (J Bacteriol 205:e00184-23, 2023, https://doi.org/10.1128/jb.00184-23) used an unbiased transposon-sequencing (Tn-seq) screen to identify proteins required for life when cells lose the RecG branched-DNA helicase (synthetic lethality). The proteins’ identities indicate pathways that prevent endogenous DNA damage, pathways that prevent its homology-directed repair (HDR) “strand-exchange” intermediates between sister chromosomes, and pathways that resolve those intermediates. All avoid intermediate pile-up, which blocks chromosome segregation, causing “death-by-recombination.” DNA damage is managed to regulate crucial but …

The prognosis of childhood medulloblastoma (MB) is often poor, and it usually requires aggressive therapy that adversely affects quality of life. microRNA-211 (miR-211) was previously identified as an important regulator of cells that descend from neural cells. Since medulloblastomas primarily affect cells with similar ontogeny, we investigated the role and mechanism of miR-211 in MB. Here we showed that miR-211 expression was highly downregulated in cell lines, PDXs, and clinical samples of different MB subgroups (SHH, Group 3, and Group 4) compared to normal cerebellum. miR-211 gene was ectopically expressed in transgenic cells from MB subgroups, and they were subjected …

Rotavirus-Mediated Dgat1 Degradation: A Pathophysiological Mechanism Of Viral-Induced Malabsorptive Diarrhea, Zheng Liu, Hunter Smith, Jeanette M Criglar, Antonio J Valentin, Umesh Karandikar, Xi-Lei Zeng, Mary K Estes, Sue E Crawford

Faculty, Staff and Students Publications

Gastroenteritis is among the leading causes of mortality globally in infants and young children, with rotavirus (RV) causing ~258 million episodes of diarrhea and ~128,000 deaths annually in infants and children. RV-induced mechanisms that result in diarrhea are not completely understood, but malabsorption is a contributing factor. RV alters cellular lipid metabolism by inducing lipid droplet (LD) formation as a platform for replication factories named viroplasms. A link between LD formation and gastroenteritis has not been identified. We found that diacylglycerol O-acyltransferase 1 (DGAT1), the terminal step in triacylglycerol synthesis required for LD biogenesis, is degraded in RV-infected cells by …

BACKGROUND: "Brain-predicted age" estimates biological age from complex, nonlinear features in neuroimaging scans. The brain age gap (BAG) between predicted and chronological age is elevated in sporadic Alzheimer disease (AD), but is underexplored in autosomal dominant AD (ADAD), in which AD progression is highly predictable with minimal confounding age-related co-pathology.

METHODS: We modeled BAG in 257 deeply-phenotyped ADAD mutation-carriers and 179 non-carriers from the Dominantly Inherited Alzheimer Network using minimally-processed structural MRI scans. We then tested whether BAG differed as a function of mutation and cognitive status, or estimated years until symptom onset, and whether it was associated with established …

Most neutralizing anti-SARS-CoV-2 monoclonal antibodies (mAbs) target the receptor binding domain (RBD) of the spike (S) protein. Here, we characterize a panel of mAbs targeting the N-terminal domain (NTD) or other non-RBD epitopes of S. A subset of NTD mAbs inhibits SARS-CoV-2 entry at a post-attachment step and avidly binds the surface of infected cells. One neutralizing NTD mAb, SARS2-57, protects K18-hACE2 mice against SARS-CoV-2 infection in an Fc-dependent manner. Structural analysis demonstrates that SARS2-57 engages an antigenic supersite that is remodeled by deletions common to emerging variants. In neutralization escape studies with SARS2-57, this NTD site accumulates mutations, including …

Parasympathetic Activity And Bronchial Hyperresponsiveness In Athletes, Audrey Badza

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

Bronchial hyperresponsiveness (BHR) is a term used to describe the bronchial constriction response to environmental stimuli. BHR is increasingly common in endurance athletes due to increased exposure to some stimuli. The purpose of this review is to evaluate Stang et al.'s (2016) article, "Parasympathetic Activity and Bronchial Hyperresponsiveness in Athletes" and discuss the significance of their results. The results concluded that BHR is related to the parasympathetic activity of the heart rather than the pupils. The study concluded that there is an association between BHR and parasympathetic activity of the heart, methacholine is associated with BHR and cardiac vagal activity, …

Review Of: Pull Through Blessings: The Colorful Tapestry Of Hirschsprung’S Disease—Lisa Sensenig And Helen Zimmerman, Adin Stauffer

Journal of Amish and Plain Anabaptist Studies

Hirschsprung’s Disease (HD) is a genetic condition found in a child born without ganglion cells in part of the intestines. Ganglion cells send signals to intestinal muscles to contract to help pass bowel movements. No signal means no bowel movement, which results in babies not eating, becoming uncomfortable and sleepy, spitting up, and if not treated, eventually dying. [First paragraph.]

Plain Anabaptists And Covid-19: A Distinct Response To Government Restrictions?, Michael Sauder

Journal of Amish and Plain Anabaptist Studies

Plain Anabaptists have a distinct way of relating to the government. Does that mean they would have distinct decision making processes in relation to government-promulgated public health restrictions regarding COVID-19? This essay argues that plain Anabaptist populations did not exhibit particularly unique decision-making and responses to COVID-19.

Partnering With The Old Order Mennonites In The Finger Lakes Region Of New York State To Identify The Mechanisms Of Protective Immunity Against Atopic Disease Development, Alexandra N. Kaplan, Camille A. Martina, Elizabeth R. Catlin, John Looney, Kirsi M. Järvinen

Journal of Amish and Plain Anabaptist Studies

Old Order Mennonites (OOM) follow a traditional agrarian lifestyle; key aspects include home births, large families, limited antibiotic usage, consumption of whole foods and unpasteurized milk, and early exposure to soil, stables, and farm animals. There is evidence that a farming lifestyle protects against asthma and allergies, yet the biological mechanisms behind this protective effect remain unknown. The “Zooming into Old Order Mennonites” (ZOOM) cohort study was established to further explore protective factors and mechanisms. This study compares immune development among OOM children from the Finger Lakes Region of New York to those residing 65 miles northwest in Rochester, NY. …

Vitamin D Status Of Anabaptist Children In Southwestern Ontario, Canada, Janis A. Randall Simpson, Natalee Miller, Taylor Hartwig, Jane Leach, Melissa Purdy, Emily Roth, Victoria Mok Siue, Cynthia Soulliere, Jacqui Tam, Ann Watt

Journal of Amish and Plain Anabaptist Studies

The objective was to determine vitamin D status of Old Order Anabaptist children in rural Southwestern, Ontario, Canada, given concerns of community healthcare professionals. Fifty-two children (2.5 months - 6.5 years) (56% female) were recruited. Finger prick blood spot (BSp) samples were analyzed for 25-hydroxy (OH) vitamins D2 & D3 (BSp25(OH)D). Three-day food records were evaluated using Dietary Reference Intakes and Canada’s Food Guide (CFG) (Bush, et al. 2007). Compared to national Canadian data: mean BSp25(OH)D concentrations (78±31 nmol/L) were similar; a slightly smaller proportion (0% vs 2%) were at risk of deficiency (<30 nmol/L) or had inadequate status (4% vs 7%) (<40 nmol/L); and 10% vs 1% had BSp25(OH)D higher than 125 nmol/L. BSp25(OH)D was significantly associated (r2=0.358; p=0.001) with total vitamin D intake. From food alone, vitamin D intake was 68±39 IU/day, lower than the Recommended Dietary Allowance (RDA) of 600 IU/day, and intakes were all below the Estimated Average Requirement (EAR) of 400 IU. Even including supplemental vitamin D, 87% were below the EAR (total intake=213±194 IU/day). No children had vitamin D intakes greater than the Upper Limit. Servings of milk and alternates were 1.6±0.8/day (CFG=2/day). Unfortified farm milk was consumed by 88% of children and 89% received a vitamin D supplement. Results were comparable to recent Canadian data suggesting that most children have adequate vitamin D status. Nevertheless, these findings support the need to encourage appropriate vitamin D intake (from food and supplements) to achieve the RDA for Old Order Anabaptist children in these communities.

Bi-Negativity: An Assessment Of Negativity Surrounding Bisexuality From The Lgbtq+ And Heterosexual Communities, Whitney R. Ford

The Confluence

This study was conducted to test the hypothesis that negative attitudes towards bisexual people (bi-negativity) exists within the LGBTQ+ and heterosexual communities and to determine if levels of bi-negativity are higher within the LGBTQ+ group. I administered the Gender-Based Attitudes Towards Bisexuality (GBAB) Scale by Nielsen et al. (2022) to measure bi-negativity using an online survey. The results, obtained from 87 participants who identify as LGBTQ+ and 121 participants who identify as heterosexual between the ages of 18 and 80, support my hypothesis that bi-negativity exists within both groups. However, contrary to my second hypothesis, higher levels of bi-negativity were …

Regulation Of Mirnas In Obesity And Diabetes, Eva Maher, Ava O'Meara, Cathy Brougham

SURE Journal: Science Undergraduate Research Experience Journal

Introduction: The prevalence of obesity and obesity-related secondary disorders has increased dramatically in recent years. Dysregulated microRNA (miRNA) expression has been linked to the development of obesity and its associated disorders. Adipose derived stem cells (ADSCs) are promising cell models of obesity, obesity-related inflammation and diabetes. Furthermore, miRNA expression profiles have emerged as promising targets for the novel treatment of diseases such as obesity. In order to enhance miRNA-based therapies, the miRNA expression profile of obesity and its related disorders must be monitored to further understand the underlying mechanisms of obesity and to identify novel targets.
