The Complement System In Covid-19: Friend And Foe?, Anuja Java, Anthony J Apicelli, M Kathryn Liszewski, Ariella Coler-Reilly, John P Atkinson, Alfred Hj Kim, Hrishikesh S Kulkarni

Open Access Publications

Coronavirus disease 2019 (COVID-19), the disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has resulted in a global pandemic and a disruptive health crisis. COVID-19-related morbidity and mortality have been attributed to an exaggerated immune response. The role of complement activation and its contribution to illness severity is being increasingly recognized. Here, we summarize current knowledge about the interaction of coronaviruses with the complement system. We posit that (a) coronaviruses activate multiple complement pathways; (b) severe COVID-19 clinical features often resemble complementopathies; (c) the combined effects of complement activation, dysregulated neutrophilia, endothelial injury, and hypercoagulability appear to be intertwined …

Molecular Pathways Elicited By Toll-Like Receptor 2 (Tlr2) Signaling During Staphylococcus Aureus Craniotomy Infection, Chinyere Agba, Cortney E. Heim, Christopher M. Horn, Tammy Kielian

Posters: 2020 Summer Undergraduate Research Program

A craniotomy is required to access the brain during neurosurgery for tumor resection or epilepsy treatment and despite extensive precautionary measures, infectious complications occur at a frequency of 1-3% (1-3). Approximately half of craniotomy infections are caused by S. aureus, which forms a biofilm on the bone flap. Our laboratory has developed a mouse model of S. aureus craniotomy-associated biofilm infection that shares important ultrastructural and MRI attributes with human disease (4). Toll-like receptor 2 (TLR2) is expressed by cells of the innate immune system and is critical for recognizing pathogen-associated molecular patterns (PAMPs) in the cell wall of gram-positive …

Living In The Impasse: British Writers And Non-Normative Identities, 1880-1940, Nicole Lawrence

Doctoral Dissertations

“Living in the Impasse: British Writers and Non-Normative Identities, 1880-1940” engages queer theory, affect theory, and literary analysis to demonstrate literature’s affective capacity to provide writers with imaginative spaces in which to express non-normative gender and sexuality and queer modes of relating. Exploring key gender or sexually non-normative writers from the late Victorian through early modernist period, the project explicates how Oscar Wilde, E.M. Forster, Radclyffe Hall, and Virginia Woolf strategically used their writing to articulate the non-normative self not yet possible to be expressed without legal jeopardy and censorship in other social contexts. This dissertation develops the concept of …

Pilot Project For Future Fast And Accurate Detection Of The Human Fecal Marker Hf183 For Presence Of Human Pollution In The New River, Angie Louis

All HCAS Student Capstones, Theses, and Dissertations

One type of pollution that has a negative impact on the environmental waters originates from fecal contamination. Identifying the source of pollution is an important step in effective resource management, mitigation, and reducing risk to human health. Microbial source tracking (MST) can be used to identify fecal pollution and to identify specific microbes in the environment and the quantitative polymerase chain reaction (qPCR) can be utilized in this analysis. In this pilot study the New River waterway, running through the City of Fort Lauderdale, was tested for a human specific bacteria Bacteroids, using the TaqMan HF183 qPCR assay (HF183/BFDrev). …

Final 5-Year Findings From The Phase 3 Helios Study Of Ibrutinib Plus Bendamustine And Rituximab In Patients With Relapsed/Refractory Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma, Gam Fraser, S Rule, Et Al

Peninsula Medical School

We report final analysis outcomes from the phase 3 HELIOS study (NCT01611090). Patients with relapsed/refractory chronic lymphocytic leukemia/small lymphocytic lymphoma without deletion 17p (n = 578) were randomized 1:1 to 420 mg daily ibrutinib or placebo plus ≤6 cycles of bendamustine plus rituximab (BR), followed by ibrutinib or placebo alone. Median follow-up was 63.7 months. Median investigator-assessed progression-free survival was longer with ibrutinib plus BR (65.1 months) than placebo plus BR (14.3 months; hazard ratio [HR] 0.229 [95% confidence interval (CI) 0.183-0.286]; p < .0001). Despite crossover of 63.3% of patients from the placebo plus BR arm to ibrutinib treatment upon disease progression, ibrutinib plus BR versus placebo plus BR demonstrated an overall survival benefit (HR 0.611 [95% CI 0.455-0.822]; p = .0010; median not reached in either arm). Long-term follow-up data confirm the survival benefit of ibrutinib plus BR over BR alone. Safety profiles were consistent with those known for ibrutinib and BR.

Forensic Autosomal Short Tandem Repeats And Their Potential Association With Phenotype, Nicole Wyner, Mark Barash, Dennis Mcnevin

Faculty Research, Scholarly, and Creative Activity

Forensic DNA profiling utilizes autosomal short tandem repeat (STR) markers to establish identity of missing persons, confirm familial relations, and link persons of interest to crime scenes. It is a widely accepted notion that genetic markers used in forensic applications are not predictive of phenotype. At present, there has been no demonstration of forensic STR variants directly causing or predicting disease. Such a demonstration would have many legal and ethical implications. For example, is there a duty to inform a DNA donor if a medical condition is discovered during routine analysis of their sample? In this review, we evaluate the …

Effect Of Cannabidiol And ∆9-Tetrahydrocannabinol Concentration On Breast Cancer Cell Viability, Dorothy Achiaa Agyemang

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

-Tetrahydrocannabinol (THC) and cannabidiol (CBD) are phytocannabinoids that have a potential impact in cancer treatments. Studies have shown that certain cannabinoids cause cancer cells to die, but only with selective concentrations, which have not been well documented. The first study of this thesis was to determine the exact concentration of CBD and THC needed to kill human MCF-7 breast cancer cells rather than create mass multiplication leading to more growth of the cancer. To conduct this experiment, cell culture was performed with a MCF-7 breast cancer cell line. The treatment groups were treated with CBD or THC at varying concentrations …

Comparative Gene Expression Profiling Between Optic Nerve And Spinal Cord Injury In Xenopus Laevis Reveals A Core Set Of Genes Inherent In Successful Regeneration Of Vertebrate Central Nervous System Axons, Morgan A. Sammons, Jamie L. Belrose, Aparna Prasad, Kurt M. Gibbs, Ben G. Szaro

Biological Sciences Faculty Scholarship

Background

The South African claw-toed frog, Xenopus laevis, is uniquely suited for studying differences between regenerative and non-regenerative responses to CNS injury within the same organism, because some CNS neurons (e.g., retinal ganglion cells after optic nerve crush (ONC)) regenerate axons throughout life, whereas others (e.g., hindbrain neurons after spinal cord injury (SCI)) lose this capacity as tadpoles metamorphose into frogs. Tissues from these CNS regions (frog ONC eye, tadpole SCI hindbrain, frog SCI hindbrain) were used in a three-way RNA-seq study of axotomized CNS axons to identify potential core gene expression programs for successful CNS axon regeneration.

Transcriptome Analysis And Expression Of Selected Cationic Amino Acid Transporters In The Liver Of Broiler Chicken Fed Diets With Varying Concentrations Of Lysine, Collins N. Khwatenge, Boniface M. Kimathi, Samuel N. Nahashon

Agricultural and Environmental Sciences Faculty Research

Amino acids are known to play a key role in gene expression regulation. Amino acid signaling is mediated via two pathways: the mammalian target of rapamycin complex 1 (mTORC1) and the amino acid responsive (AAR) pathways. Cationic amino acid transporters (CATs) are crucial in these pathways due to their sensing, signaling and transport functions. The availability of certain amino acids plays a key role in the intake of other amino acids, hence affecting growth in young birds. However, the specific mechanism for regulating lysine transport for growth is not clear. In this study, we analyze the transcriptome profiles and mRNA …

Characterization Of The Biogeography And Temporal Dynamics Of The Trachymyrmex Septentrionalis Fungus Garden Microbiome, Kevin Lee

Doctoral Dissertations

Like all fungus-growing ants, Trachymyrmex septentrionalis engages in an obligate mutualism with a Basidiomycete fungus that it raises as its primary nutrition source. Therefore, the success of the symbiosis is dependent upon the health of the fungus garden containing this fungus, which may be affected by the composition of its microbiome. Most of what is known about fungus garden microbiomes comes from studies of the Neotropical fungus growing ants, especially the most evolutionarily derived and economically impactful “leaf-cutting” species. Although fungus-farming ants inhabit a vast range, little is known about how dispersal of microbes from their biogeographically and temporally distinct …

Stress And Negative Affect As Mediators In The Association Between Parental Social Support And Lung Function In Adolescents With Asthma, Amber Osorno, Eric Sternlicht, Pornchai Tirakitsoontorn, Azucena Talamantes, Anchalee Yuengsrigul, Zeev N. Kain, Brooke Jenkins

SURF Posters and Papers

Asthma is the leading chronic condition amongst children in the United States as 7.5% of children are diagnosed with asthma. Studies have shown that positive social support is associated with positive asthma management. A strong social support system predicts good management of asthma symptoms; however, current literature has not yet examined how social support impacts lung function as opposed to merely symptom management. Stress and negative affect have been revealed to be associated with worse asthma control, as well as exacerbation of symptoms. Stressful situations, such as the death of a family member, unemployment, and familial tensions lead to worsening …

Perceptions Of Elementary School Support Staff Of Their Role In Supporting The School Mission Statement, Matthew Dean

Dissertations

School district mission statements are intended to be unifying declarations that set a tone and direction for organizations and provide a unifying motivator for the individuals who serve those organizations (Rey, 2017). School district mission statements should be created and articulated in a manner that can be understood and followed by certified administrators and teachers, as well as classified personnel such as district support staff (Lynch, 2016). Without adequate articulation, school district mission statements can fall short of providing guidance and motivation to every employee in the district (Rey, 2017). This qualitative study was initiated to gain the perceptions of …

Exploring Korean Hand Therapy In Treating Plantar Fasciitis: A Pilot Study, Alice A-Hui Osborn Fetzer

Theses and Dissertations

PF is one of the most common foot and ankle problems. People with PF experience mild to severe pain that interferes moderately with activities of daily living (ADL). Due to chronic pain that interferes with ADL, people with PF often use non-steroidal anti-inflammatory medications and/or acetaminophen. These medications alleviate pain but cannot eliminate it. Additionally, with chronic use, these medications can cause well-known adverse side effects. The purposes of this study were to investigate the effect of Korean Hand Therapy (KHT) in (1) treating the pain experienced in patients with plantar fasciitis (PF), (2) evaluating its impact on functionality, and …

Algal Coverage Detection And Classification Using Envi: Correlation With Dissolved Oxygen Levels In Elkhorn Slough, Ca, Jason Dawson

All HCAS Student Capstones, Theses, and Dissertations

Estuaries are exposed to varying stressors, whether they be physical, chemical, or environmental. The most notable of stressors is eutrophication of coastal and inland ecosystems. This is a result of increased supply of nutrients fueling production within the system. One outcome of this increased nutrient load to the system is that of algal blooms. These blooms can impact the aesthetic appearance and degrade the quality of health of the system. Many of these coastal zones and waterways are critical habitats for many biological (some endangered) species and serve as recreational areas for human populations. Elkhorn Slough, California is one of …

A Study Of The Relationship Between Uric Acid And Substantia Nigra Brain Connectivity In Patients With Rem Sleep Behavior Disorder And Parkinson’S Disease, Timothy M. Ellmore, Jessika Suescun, Richard J. Castriotta, Mya C. Schiess

Publications and Research

Low levels of the natural antioxidant uric acid (UA) and the presence of REM sleep behavior disorder (RBD) are both associated with an increased likelihood of developing Parkinson’s disease (PD). RBD and PD are also accompanied by basal ganglia dysfunction including decreased nigrostriatal and nigrocortical resting state functional connectivity. Despite these independent findings, the relationship between UA and substantia nigra (SN) functional connectivity remains unknown. In the present study, voxelwise analysis of covariance was used in a cross-sectional design to explore the relationship between UA and whole-brain SN functional connectivity using the eyes-open resting state fMRI method in controls without …

Pharmaceutical Sciences and Research

An emerging coronavirus, SARS-CoV-2, is the causative agent for the ongoing pandemic of coronavirus disease 2019 (COVID-19), which has caused a worldwide social and economic disruption. Currently, no antiviral drugs with proven clinical efficacy, or vaccines for its prevention. Therefore, to combat the pandemic of this novel coronavirus, new effective treatments are urgently needed. In the process of traditional drug development, developing new drugs from scratch is a time- consuming process, requires high-investment, and is a high-risk process, which is impractical to face the immediate global challenge of the SARS-CoV-2 pandemic. Drug repurposing strategy is one of the effective ways …

Aims: Mesencephalic astrocyte-derived neurotrophic factor (MANF) is a secretory neurotrophic factor protein that promotes repair after neuronal injury. The microglia cell surface receptor (triggering receptor expressed on myeloid cells-2; TREM2) regulates the production of pro- and antiinflammatory mediators after stroke. Here, we study MANF and TREM2 expression after middle cerebral artery occlusion (MCAo) and explore if docosahexaenoic acid (DHA) treatment exerts a potentiating effect. Methods: We used 2 hours of the MCAo model in rats and intravenously administered DHA or vehicle at 3 hours after the onset of MCAo. Neurobehavioral assessment was performed on days 1, 3, 7, and 14; …
