Rapid Invasion By The Annual Grass Ventenata Dubia Into Protected-Area, Low-Elevation Sagebrush Steppe, Melissa Nicolli, Thomas J. Rodhouse, Devin S. Stucki, Matthew Shinderman

Western North American Naturalist

Wiregrass (Ventenata dubia [Leers] Coss.), an annual grass from the Mediterranean region of North Africa and Eurasia that has aggressive invasion potential in many North American plant communities, has only recently been reported in low-elevation sagebrush steppe. We first encountered wiregrass in 2014 in the John Day Fossil Beds National Monument, a low-elevation steppe protected area in central Oregon. This discovery was incidental to formal vegetation monitoring that was initiated in the monument in 2009. We first encountered wiregrass in monitoring plots in 2016, and, from plot data, we documented rapid spread during 2017–2019. Wiregrass infestation increased within our …

Interactions Of Deet And Novel Repellents With Mosquito Odorant Receptors, Gariel G. Grant, Rachel R. Estrera, Narendra Pathak, C. Dennis Hall, Maia Tsikolia, Kenneth J. Linthicum, Ulrich R. Bernier, Adam C. Hall

Neuroscience: Faculty Publications

The carboxamide N,N-di-ethyl-meta-Toluamide (DEET) is the most effective and widely used insect repellent today. However, drawbacks concerning the efficacy and the safety of the repellent have led to efforts to design new classes of insect repellents. Through quantitative structure-Activity relationships, chemists have discovered two chemical groups of novel repellents: The acylpiperidines and the carboxamides, with the acylpiperidines generally more potent in biological assays. Although the exact mechanism of action of DEET and other repellents has not yet been thoroughly elucidated, previous research shows that the activity of insect odorant receptors are inhibited in the presence of repellents. The present electrophysiological …

Integrating Field Methods, Remote Sensing And Modeling To Monitor Climate-Adapted Tidal Marsh Restoration, Alexandra S. Thomsen

AES Theses

Sea level rise threatens coastal wetlands worldwide. In response, wetland restoration projects are implementing strategies that decrease vulnerability to this threat. Vegetation monitoring at sites employing new restoration strategies, including determination of appropriate and efficient monitoring techniques, is critical to improve understanding of factors leading to restoration success and maximize benefits of future projects. In Central California, sediment addition raised a degraded marsh plain to a high elevation expected to be resilient to sea level rise over the next century. We conducted area searches of plant survival and modeled effects of nine predictors on new vegetation cover using two monitoring …

Associating Landscape Variables With Nesting Occupancy And Success Of Songbirds Using Nest Boxes In Semi-Urban Greenspaces, Amanda Preece

AES Theses

Habitat fragmentation and loss of biodiversity due to urbanization is happening at a rapid pace. Greenspaces within our cities can provide habitat for native species, and effective management of urban and semi-urban parks is an increasingly important way to support these species. I compared landscape metrics surrounding nest boxes used by five avian species in four semi-urban parks of central coastal California, USA, to determine which land cover elements best predicted nest box occupancy and success. Five species were included in this study – Ash-throated Flycatcher (Myiarchus cinerascens), Chestnut-backed Chickadee (Poecile rufescens), Oak Titmouse (Baeolophus …

Beauty Is Not Black And White: A Content Analysis Of Black Women’S Body Image In Television Media, Alexis Hubbard

Graduate Theses and Dissertations

There are few bodies of literature that look at Black women’s body image in television media. When Black women were studied most research (Falconer & Neville, 2000; Jhally & Kilbourne, 2010; Smith, 2014; Shearon-Richardson, 2011;) compared them to White ideals. However, this study did a content analysis of Black women in predominantly Black or ethnically diverse television shows using qualitative studies that suggest a Black ideal. The researcher examined lead character(s) body shapes, comments about their body, hair texture and comments about their hair. This research looked at protective factors (aspects Black life that allow for more body satisfaction) like …

Microbial Experience Influences Tumor- Infiltrating T Lymphocytes, Hanna Groeber

Masters Theses

Immune cells, including T cells, have been used for anti-cancer therapy with varying degrees of success. One potential reason for immunotherapy failures in clinical trials may be that typical specific pathogen free (SPF) mice do not accurately replicate human microbial experience, which has important influence on shaping the adaptive immune response. Recently, several previous studies have shown that the immune system of SPF mice more closely resembles newborn human immunity, whereas immune systems from mice exposed to diverse pathogens more closely reflect adult human immunity.

To study the impact of microbial experience on the immune response, we have adopted a …

Connecting Meaningful Moments: Exploring Empathy Through Storytelling, Samantha Maida

Theses

As individuals transition through life, it is growing more and more difficult for everyone to live in the same world when perceptions of situations are skewed. Each individuals’ perception is colored by their life’s experiences which give rise to a distorted view of the world, creating biases, and affirming that our perception is a product of our past that is pushing forward into our future. The more technology promotes isolation and damages in-person communication, the more individuals are growing less aware of those around them, and how their experiences, and life events affect the way they view and respond to …

Diagnosis And Management Of Malignant Peripheral Nerve Sheath Tumors: Current Practice And Future Perspectives, Bethany C Prudner, Tyler Ball, Richa Rathore, Angela C Hirbe

2020-Current year OA Pubs

One of the most common malignancies affecting adults with the neurofibromatosis type 1 (NF1) cancer predisposition syndrome is the malignant peripheral nerve sheath tumor (MPNST), a highly aggressive sarcoma that typically develops from benign plexiform neurofibromas. Approximately 8-13% of individuals with NF1 will develop MPNST during young adulthood. There are few therapeutic options, and the vast majority of people with these cancers will die within 5 years of diagnosis. Despite efforts to understand the pathogenesis of these aggressive tumors, the overall prognosis remains dismal. This manuscript will review the current understanding of the cellular and molecular progression of MPNST, diagnostic …

Disease And Treatment Patterns Among Patients With Pouch-Related Conditions In A Cohort Of Large Tertiary Care Inflammatory Bowel Disease Centers In The United States, Edward L Barnes, Laura Raffals, Millie D Long, Gaurav Syal, Maia Kayal, Ashwin Ananthakrishnan, Benjamin Cohen, Joel Pekow, Parakkal Deepak, Jean-Frederic Colombel, Hans H Herfarth, Robert S Sandler

2020-Current year OA Pubs

BACKGROUND: Gaps exist in our understanding of the clinical course of pouch-related disorders.

METHODS: We evaluated baseline disease activity and longitudinal treatment patterns among patients with inflammatory conditions of the pouch.

RESULTS: Among 468 patients with an ileal pouch-anal anastomosis (IPAA), 94 (20%) had acute pouchitis, 96 (21%) had chronic pouchitis, and 192 (41%) had Crohn disease of the pouch. Following an IPAA, 38% of patients were treated with a biologic and 11% underwent inflammatory bowel disease- or bowel-related surgery.

CONCLUSIONS: Treatment patterns after IPAA indicate that pouch-related disorders have a significant impact on individual patients and the healthcare system.

Transcriptomes From German Shepherd Dogs Reveal Differences In Immune Activity Between Atopic Dermatitis Affected And Control Skin, K Tengvall, K Bergvall, M Olsson, B Ardesjö-Lundgren, F H G Farias, M Kierczak, Å Hedhammar, K Lindblad-Toh, G Andersson

2020-Current year OA Pubs

Canine atopic dermatitis (CAD) is an inflammatory and pruritic allergic skin disease with both genetic and environmental risk factors described. We performed mRNA sequencing of non-lesional axillary skin biopsies from nine German shepherd dogs. Obtained RNA sequences were mapped to the dog genome (CanFam3.1) and a high-quality skin transcriptome was generated with 23,510 expressed gene transcripts. Differentially expressed genes (DEGs) were defined by comparing three controls to five treated CAD cases. Using a leave-one-out analysis, we identified seven DEGs: five known to encode proteins with functions related to an activated immune system (CD209, CLEC4G, LOC102156842 (lipopolysaccharide-binding protein-like), LOC480601 (regakine-1-like), LOC479668 …

Aggressive Angiomyxoma In The Ischiorectal Fossa, Asra Wahid, Abdul Hakeem, Sadaf Khan

Medical College Documents

Aggressive Angiomyxoma (AA) is a soft tissue tumour that principally affects women of the reproductive age, primarily involving the pelvis and the perineum. Despite being slow growing, it is classified as aggressive due to its locally infiltrative nature and high recurrence. It is rare, often asymptomatic and is misdiagnosed. However, it has characteristic features on radiographic imaging. Complete surgical resection is the ideal approach to treat AA. We report a case of an aggressive angiomyxoma in a 17 year old female, located in the ischiorectal fossa and diagnosed incidentally on a magnetic resonance imaging (MRI). The lesion was excised without …

Objectives: Ewing's sarcoma is an aggressive malignancy of bone and soft tissue in children and young adults. Despite advances in modern therapy, metastasis can occur and results in high mortality. The objective of this study was to identify whether the signaling transduction proteins, insulin growth factor receptor (IGF1R) and S6 kinase (S6K), can predict poor prognosis in Ewing's sarcoma.

Methods: After the Institutional Research Board approval, immunohistochemical experiments on tissue microarray slides containing 32 archived Ewing's sarcoma tumor samples were performed with antibodies against IGF1Rb and p-S6K. Immunohistochemical staining results were correlated with patients' clinical data including clinical stage and …

Palbociclib Treatment Alters Nucleotide Biosynthesis And Glutamine Dependency In A549 Cells, Lindsey R. Conroy, Pawel Lorkiewicz, Liqing He, Xinmin Yin, Xiang Zhang, Shesh N. Rai, Brian F. Clem

Neuroscience Faculty Publications

Background

Aberrant activity of cell cycle proteins is one of the key somatic events in non-small cell lung cancer (NSCLC) pathogenesis. In most NSCLC cases, the retinoblastoma protein tumor suppressor (RB) becomes inactivated via constitutive phosphorylation by cyclin dependent kinase (CDK) 4/6, leading to uncontrolled cell proliferation. Palbociclib, a small molecule inhibitor of CDK4/6, has shown anti-tumor activity in vitro and in vivo, with recent studies demonstrating a functional role for palbociclib in reprogramming cellular metabolism. While palbociclib has shown efficacy in preclinical models of NSCLC, the metabolic consequences of CDK4/6 inhibition in this context are largely unknown.
