Headstarting Eastern Box Turtles In Southwest Michigan: Implications For Growth, Survival, And Spatial Ecology, Faith C. Kuzma

Masters Theses

Turtles and tortoises are one of the most endangered groups of animals in the world as anthropogenic activities like overexploitation, collection for the pet trade, and habitat loss and fragmentation have caused dramatic population declines in recent years. As a result, proactive conservation techniques are being increasingly implemented to facilitate population recovery. Headstarting is a popular chelonian conservation technique that aims to reduce vulnerability and increase survival of juvenile turtles. While headstarting has been a valuable tool for many species, there is increasing evidence that species-specific influences impact its success. In this study, we headstarted four annual cohorts of eastern …

Behrman, Tomás Huanca, William R. Leonard, Victoria Reyes-García, Asher Rosinger, Susan Tanner, Eduardo A. Undurraga, Ariela Zycherman

Department of Agricultural Economics Faculty Publications

Knowing what happens over time to the lifeways of people in contemporary small-scale non-industrial societies of the rural Global South matters because it helps assess changes in the quality of life of underrepresented groups. It has been hard to answer the question because longitudinal information is rarely collected in such settings. A longitudinal dataset of nine years (2002–2010) from a horticultural-foraging society of Indigenous People in the Bolivian Amazon (Tsimane’) is used for an exploratory analysis of micro-level trends in indicators of well-being and economic inequalities. We selected 13 Tsimane’ villages (from ∼ 100) that varied in proximity to town …

Computational Analysis Of Cas Proteins Unlocks New Potential In Hiv-1 Targeted Gene Therapy, Will Dampier, Rachel Berman, Michael Nonnemacher, Brian Wigdahl

Kimmel Cancer Center Faculty Papers

Introduction: The human immunodeficiency virus type 1 (HIV-1) pandemic has been slowed with the advent of anti-retroviral therapy (ART). However, ART is not a cure and as such has pushed the disease into a chronic infection. One potential cure strategy that has shown promise is the Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas gene editing system. It has recently been shown to successfully edit and/or excise the integrated provirus from infected cells and inhibit HIV-1 in vitro, ex vivo, and in vivo. These studies have primarily been conducted with SpCas9 or SaCas9. However, additional Cas proteins are …

Factors Associated With Blood Mercury Concentrations And Their Interactions With Three Glutathione S-Transferase Genes (Gstt1, Gstm1, And Gstp1): An Exposure Assessment Study Of Typically Developing Jamaican Children, Manouchehr Hessabi, Katherine A Loveland, Mohammad H Rahbar

Faculty, Staff and Student Publications

BACKGROUND: Jamaican soil is abundant in heavy metals including mercury (Hg). Due to availability and ease of access, fish is a traditional dietary component in Jamaica and a significant source of Hg exposure. Mercury is a xenobiotic and known neuro-toxicant that affects children's neurodevelopment. Human glutathione S-transferase (GST) genes, including GSTT1, GSTM1, and GSTP1, affect Hg conjugation and elimination mechanisms.

METHODS: In this exposure assessment study we used data from 375 typically developing (TD) 2-8-year-old Jamaican children to explore the association between environmental Hg exposure, GST genes, and their interaction effects on blood Hg concentrations (BHgCs). We used multivariable general …

Soil Carbon And Nitrogen After Eight Years Of Rotational Grazing In The Nebraska Sandhills Meadows, Gandura O. Abagandura, Martha Mamo, W. H. Schacht, Aaron Shropshire, Jerry Volesky

Department of Agronomy and Horticulture: Faculty Publications

Grassland provides many ecosystem services; therefore, sustainable management practices of grassland are crucial for maintaining and enhancing its ecosystem health and resilience. Rotational grazing at a high stocking density (a.k.a., ultrahigh stocking density) is purported to sequester greater amounts of carbon (C) in grassland soils than rotational grazing at low stocking densities. This study was conducted in the Nebraska Sandhills meadows for eight years to evaluate how rotational grazing with different stocking densities can affect soil C and total nitrogen (TN) in bulk soils, soil organic matter fractions, and sequestration rate. The grazing management included a high stocking density with …

Contributions Of The Microbiome-Derived Metabolome For Risk Assessment And Prognostication Of Pancreatic Cancer, Ricardo A León-Letelier, Rongzhang Dou, Jody Vykoukal, Michele T Yip-Schneider, Anirban Maitra, Ranran Wu, Kim-An Do, Jianjun Zhang, C Max Schmidt, Samir Hanash, Johannes F Fahrmann

Faculty, Staff and Student Publications

Background: Increasing evidence implicates microbiome involvement in the development and progression of pancreatic ductal adenocarcinoma (PDAC). Studies suggest that reflux of gut or oral microbiota can lead to colonization in the pancreas, resulting in dysbiosis that culminates in release of microbial toxins and metabolites that potentiate an inflammatory response and increase susceptibility to PDAC. Moreover, microbe-derived metabolites can exert direct effector functions on precursors and cancer cells, as well as other cell types, to either promote or attenuate tumor development and modulate treatment response.

Content: The occurrence of microbial metabolites in biofluids thereby enables risk assessment and prognostication of PDAC, …

Faculty, Staff and Student Publications

Therapeutic resistance remains a major obstacle to successful clinical management of diffuse intrinsic pontine glioma (DIPG), a high-grade pediatric tumor of the brain stem. In nearly all patients, available therapies fail to prevent progression. Innovative combinatorial therapies that penetrate the blood-brain barrier and lead to long-term control of tumor growth are desperately needed. We identified mechanisms of resistance to radiotherapy, the standard of care for DIPG. On the basis of these findings, we rationally designed a brain-penetrant small molecule, MTX-241F, that is a highly selective inhibitor of EGFR and PI3 kinase family members, including the DNA repair protein DNA-PK. Preliminary …

Faculty, Staff and Student Publications

Immune checkpoint inhibitors (ICI) are important treatment options for metastatic non-small cell lung cancer (mNSCLC). However, not all patients benefit from ICIs and can experience immune-related adverse events (irAEs). Limited understanding exists for germline determinants of ICI efficacy and toxicity, but Human Leukocyte Antigen (HLA) genes have emerged as a potential predictive biomarker. We performed HLA typing on 85 patients with mNSCLC, on ICI therapy and analyzed the impact of HLA Class II genotype on progression free survival (PFS), overall survival (OS), and irAEs. Most patients received pembrolizumab (83.5%). HLA-DRB4 genotype was seen in 34/85 (40%) and its presence correlated …

Exploring The Significance Of The Traditional Chef’S Uniform In Making Sense Of Professionalism In Culinary Arts Using Interpretative Phenomenological Analysis, Orla Mc Connell

European Journal of Food Drink and Society

Previous studies have found that professionalism is an important success factor for chefs. Yet, research on what professionalism “means” to chefs, and how they “make sense” of it, is currently underexplored. While there is some evidence of the significance of the traditional chef’s uniform in professional identity formation, it also needs further consideration. Culinary arts lecturers and chefs have already contributed to these discussions, but the student voice remains largely unknown. Alongside this, there is no prior research specifically on professionalism in culinary arts in Ireland. Therefore, a research gap emerged, which this paper intends to address. Using interpretative phenomenological …

Eristalis Tenax Movement Behavior In Response To Light, Temperature, And Food, Jeffery J. Zheng, Zdena M. Janderova, Jason D. Lang

Georgia Journal of Science

Drone flies, Eristalis tenax (Diptera: Syrphidae), are important generalist pollinators and visit flowers globally that range widely in color. The flies’ photoreceptors allow them to sense light wavelengths between 300-600 nm and E. tenax exhibit a positive phototactic response. To understand the effects of light on E. tenax movement, we conducted two-choice behavioral tests to determine their phototactic response to different wavelengths of light across the spectrum (ultraviolet to red light, plus full spectrum white light). The drone flies moved most and quickest toward sunlight, with almost twice the percentage of flies moving toward sunlight than toward black and …

Crispr-Cas9 Base Editing Of Pathogenic Camkiiδ Improves Cardiac Function In A Humanized Mouse Model, Wei Tan, Hui Li, John R Mcanally, Kenian Chen, Lin Xu, Philipp E Scherer, Ning Liu, Rhonda Bassel-Duby, Eric N Olson

Faculty, Staff and Student Publications

Cardiovascular diseases are the most common cause of worldwide morbidity and mortality, highlighting the necessity for advanced therapeutic strategies. Ca2+/calmodulin-dependent protein kinase IIδ (CaMKIIδ) is a prominent inducer of various cardiac disorders, which is mediated by 2 oxidation-sensitive methionine residues within the regulatory domain. We have previously shown that ablation of CaMKIIδ oxidation by CRISPR-Cas9 base editing enables the heart to recover function from otherwise severe damage following ischemia/reperfusion (IR) injury. Here, we extended this therapeutic concept toward potential clinical translation. We generated a humanized CAMK2D knockin mouse model in which the genomic sequence encoding the entire regulatory domain was …

Cell Cycle Arrest Induces Lipid Droplet Formation And Confers Ferroptosis Resistance, Hyemin Lee, Amber Horbath, Lavanya Kondiparthi, Jitendra Kumar Meena, Guang Lei, Xiaoguang Liu, Pranavi Koppula, Mi Li, Iqbal Mahmud, Bo Wei, Philip L Lorenzi, Khandan Keyomarsi, Masha V Poyurovsky, Kellen Olszewski, Boyi Gan

Faculty, Staff and Student Publications

How cells coordinate cell cycling with cell survival and death remains incompletely understood. Here, we show that cell cycle arrest has a potent suppressive effect on ferroptosis, a form of regulated cell death induced by overwhelming lipid peroxidation at cellular membranes. Mechanistically, cell cycle arrest induces diacylglycerol acyltransferase (DGAT)-dependent lipid droplet formation to sequester excessive polyunsaturated fatty acids (PUFAs) that accumulate in arrested cells in triacylglycerols (TAGs), resulting in ferroptosis suppression. Consequently, DGAT inhibition orchestrates a reshuffling of PUFAs from TAGs to phospholipids and re-sensitizes arrested cells to ferroptosis. We show that some slow-cycling antimitotic drug-resistant cancer cells, such as …

Faculty, Staff and Student Publications

Host anti-viral factors are essential for controlling SARS-CoV-2 infection but remain largely unknown due to the biases of previous large-scale studies toward pro-viral host factors. To fill in this knowledge gap, we perform a genome-wide CRISPR dropout screen and integrate analyses of the multi-omics data of the CRISPR screen, genome-wide association studies, single-cell RNA-Seq, and host-virus proteins or protein/RNA interactome. This study uncovers many host factors that are currently underappreciated, including the components of V-ATPases, ESCRT, and N-glycosylation pathways that modulate viral entry and/or replication. The cohesin complex is also identified as an anti-viral pathway, suggesting an important role of …
