Paracrine Effect Of Nrg1 And Hgf Drives Resistance To Mek Inhibitors In Metastatic Uveal Melanoma., Hanyin Cheng, Mizue Terai, Ken Kageyama, Shinji Ozaki, Peter Mccue, Takami Sato, Andrew E. Aplin

Department of Cancer Biology Faculty Papers

Uveal melanoma patients with metastatic disease usually die within one year, emphasizing an urgent need to develop new treatment strategies for this cancer. MEK inhibitors improve survival in cutaneous melanoma patients but show only modest efficacy in metastatic uveal melanoma patients. In this study, we screened for growth factors that elicited resistance in newly characterized metastatic uveal melanoma cell lines to clinical-grade MEK inhibitors, trametinib and selumetinib. We show that neuregulin 1 (NRG1) and hepatocyte growth factor (HGF) provide resistance to MEK inhibition. Mechanistically, trametinib enhances the responsiveness to NRG1 and sustained HGF-mediated activation of AKT. Individually targeting ERBB3 and …

Ketamine For The Treatment Of Depression In Patients Receiving Hospice Care: A Retrospective Medical Record Review Of Thirty-One Cases., Alana Iglewicz, Katherine Morrison, Richard A. Nelesen, Tingting Zhan, Boris Iglewicz, Nathan Fairman, Jeremy M. Hirst, Scott A. Irwin

Department of Pharmacology and Experimental Therapeutics Faculty Papers

BACKGROUND: Depression is prevalent in patients receiving hospice care. Standard antidepressant medications do not work rapidly enough in this setting. Evidence suggests that ketamine rapidly treats treatment refractory depression in the general population. Ketamine׳s role for treating depression in the hospice population warrants further study.

METHODS: A retrospective medical record review of 31 inpatients receiving hospice care who received ketamine for depression on a clinical basis was conducted. The primary outcome measure was the Clinical Global Impression Scale, which was used retrospectively to rate subjects׳ therapeutic improvement, global improvement, and side effects from ketamine over 21 days. Additionally, time to …

A Quantitative Assessment Of The January 2010 Cold Spell Effect On Mangrove Utilizing Coral Reef Fishes From Biscayne National Park, Florida, Jeffrey M. Ellis

HCNSO Student Theses and Dissertations

This study examined the effects of the January 2010 cold spell on mangrove utilizing coral reef fishes off the southeast coast of Florida, USA, in the vicinity of Biscayne National Park (BNP). An ongoing, fishery-independent mangrove visual survey documenting fish assemblages in BNP provided data from the years 1998 to 2014 for examination. Of particular interest were the presence, abundance, and size structure for five mangrove utilizing coral reef fishes: sergeant major (Abudefduf saxatilis), yellowfin mojarra (Gerres cinereus), schoolmaster snapper (Lutjanus apodus), gray snapper (Lutjanus griseus), and great barracuda (Sphyraena barracuda …

Assessment Of Nursery-Raised Acropora Cervicornis Transplants In The Upper Florida Keys, Matthew Ware

HCNSO Student Theses and Dissertations

Over the last 40 years, the Caribbean has lost half of its live coral cover, mostly in the form of Acropora cervicornis and A. palmata, due to disease, bleaching from rising water temperatures, and other stressors. To help restore these corals to reefs in Florida, the Coral Restoration Foundation (CRF) created nearshore nurseries and transplanted over 30,000 acroporid colonies across the Florida Keys. The objective of this thesis was to evaluate the growth, survivorship, and condition of nursery-raised A. cervicornis colonies that were part of two transplant projects: 1) photographic analyses of 17 past CRF transplant projects over the …

Connectivity Of Reef Fishes Between Mangroves And Coral Reefs In Broward County, Florida, Jennifer Savaro

HCNSO Student Theses and Dissertations

Many marine fishes use the mangrove ecosystem for foraging, protection, spawning, and as a nursery habitat. To develop a better understanding of energy flow between the coastal mangrove and coral reef ecosystems, the ontogentic migration and trophic connectivity of reef fishes were examined through the use of carbon (C), nitrogen (N), and oxygen (O) stable isotope ratios. Juvenile and adult gray snapper Lutjanus griseus, lane snapper L. synagris, bluestriped grunt Haemulon sciurus, French grunt H. flavolineatum, sailor’s choice H. parra, yellowfin mojarra Gerres cinereus, and great barracuda Sphyraena barracuda were collected from both mangrove …

Staghorn Coral, Acropora Cervicornis, Restoration In South Florida: Growth And Survivorship Of Outplanted Nursery Corals, Meaghan Johnson

HCNSO Student Theses and Dissertations

This thesis provides a detailed analysis of the growth and survivorship of outplanted Acropora cervicornis corals from underwater nurseries within three regions of the Florida Reef Tract. Substantial loss of stony coral cover on Florida’s coral reefs, including the branching staghorn coral, Acropora cervicornis, has occurred for decades due to disturbances such as disease, temperature induced bleaching, hurricanes, sedimentation, and pollution. This rapid population decline contributed to A. cervicornis being listed as a threatened species under the U.S. Endangered Species Act in May 2006. To aid in the recovery of the species, coral fragments were grown in underwater nurseries …

Cross-Shelf And Latitudinal Benthic Community Investigation In The Nearshore Habitats Of The Northern Florida Reef Tract, Katelyn Klug

HCNSO Student Theses and Dissertations

The Florida Reef Tract (FRT) extends from the tropical Caribbean northward along the Florida coast into a warm temperate environment where tropical reef communities diminish with increasing latitude. This study was designed to map the nearshore benthic habitats including coral reefs and evaluate how the benthic communities differ between habitats and along the coast.

Benthic communities across the northern FRT from Key Biscayne to Hillsboro Inlet (25.5°-26.3° N) were digitized from aerial photography taken in 2013 at a 1:1,000 scale. Three main hard-bottom habitat types were identified that ran parallel to shore and consecutively further away from shore: Colonized Pavement, …

A Revision Of The Genera Of Charitometridae With Abruptly Expanded Genital Pinnules, Alois Romanowski

HCNSO Student Theses and Dissertations

Feather star (Echinodermata: Crinoidea: Comatulida) family Charitometridae has not been revised since 1950. Molecular analysis, new specimens of existing species, and the discovery of a new species has revealed the need for a generic-level revision of those genera that exhibit abruptly expanded genital pinnules. A morphological study was conducted using 57 specimens representing 10 species of the Charitometridae. The genus Poecilometra is redescribed, and two species formerly placed in Strotometra have been moved to the genus based primarily on possession of pedunculate genital pinnules and a wide flange on the first pinnular of the proximal pinnules. A new species was …

Delimiting Species And Varieties Of Cycladenia Humilis (Apocynaceae), Holly Kathryn Brabazon

Student Works

Taxonomic delimitation of rare species is vital for accurate assessments of diversity and for their conservation. Cycladenia humilis, the sole species of Cycladenia, is an enigmatic perennial widely dispersed across the western United States. Within this species there are three currently recognized varieties: C. humilis var. humilis in Northern California, C. humilis var. venusta in Southern California, and C. humilis var. jonesii in Utah and Northern Arizona. Some populations occur geographically in areas between the typical distribution of each variety and the presently accepted taxonomy inadequately addresses these populations. Using five nDNA regions, we seek to clarify relationships between current …

Foregrounding The Research Log In Information Literacy Instruction, Louise R. Fluk

Publications and Research

Updating an earlier study, this article reviews the literature of information literacy (IL) instruction since 2008 for empirical evidence of the value of research logs or research journals for effective pedagogy, assessment, and prevention of plagiarism in IL instruction at the college level. The review reveals a mismatch between the acknowledged theoretical and practical value of research log assignments and the mixed advocacy for them in the literature. The article further analyzes the literature for the drawbacks of research log assignments and points toward ways of mitigating these drawbacks.

Monitoring The Progression Of Spontaneous Articular Cartilage Healing With Infrared Spectroscopy, Megan P. O'Brien, Madhuri Penmatsa, Uday Palukuru, Paul West, Xu Yang, Mathias P. G. Bostrom, Theresa Freeman, Nancy Pleshko

Publications and Research

Objective. Evaluation of early compositional changes in healing articular cartilage is critical for understanding tissue repair and for therapeutic decision-making. Fourier transform infrared imaging spectroscopy (FT-IRIS) can be used to assess the molecular composition of harvested repair tissue. Furthermore, use of an infrared fiber-optic probe (IFOP) has the potential for translation to a clinical setting to provide molecular information in situ. In the current study, we determined the feasibility of IFOP assessment of cartilage repair tissue in a rabbit model, and assessed correlations with gold-standard histology.

Design. Bilateral osteochondral defects were generated in mature white New Zealand rabbits, and …

Modeling Impacts Of Changes In Temperature And Water Table On C Gas Fluxes In An Alaskan Peatland, Jia Deng, Changsheng Li, Steve Frolking

Earth Sciences

Northern peatlands have accumulated a large amount of organic carbon (C) in their thick peat profile. Climate change and associated variations in soil environments are expected to have significant impacts on the C balance of these ecosystems, but the magnitude is still highly uncertain. Verifying and understanding the influences of changes in environmental factors on C gas fluxes in biogeochemical models are essential for forecasting feedbacks between C gas fluxes and climate change. In this study, we applied a biogeochemical model, DeNitrification-DeComposition (DNDC), to assess impacts of air temperature (T_A) and water table (WT) on C gas fluxes …

Detecting Grain Flow Rate Using A Laser Scanner, Hossein Navid, Randal K. Taylor, Arzu Yazgi, Ning Wang, Yeyin Shi, Paul Weckler

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Detecting and measuring agricultural material flow is important in a wide range of applications in agricultural engineering, such as material handling, food processing, yield monitoring, and fertilizer spreading. In these applications, flow rate is determined by measuring material mass or volume as a function of time. Although different materials require detection, the methods for a given material type (e.g., granular) can be similar. Researchers have developed methods such as impact based sensors, radiometric-based sensors, and optical methods to detect and measure material flow. Abdul Rahim and Green (1998) studied an optical-fiber sensor (containing 32 light sources and 32 light detectors) …

Explicit And Inferred Motives For Nonsuicidal Self-Injurious Acts And Urges In Borderline And Avoidant Personality Disorders, Avigal Snir, Eshkol Rafaeli, Reuma Gadassi, Kathy R. Berenson, Geraldine Downey

Psychology Faculty Publications

Nonsuicidal self-injury (NSSI) is a perplexing phenomenon that may have differing motives. The present study used experience sampling methods (ESM) which inquired explicitly about the motives for NSSI, but also enabled a temporal examination of the antecedents/consequences of NSSI; these allow us to infer other motives which were not explicitly endorsed. Adults (n = 152, aged 18–65) with borderline personality disorder (BPD), avoidant personality disorder (APD), or no psychopathology participated in a 3-week computerized diary study. We examined 5 classes of explicit motives for engaging in NSSI, finding support primarily for internally directed rather than interpersonally directed ones. We then …

Radiobiological Evaluation Of Intensity Modulated Radiation Therapy Treatments Of Patients With Head And Neck Cancer: A Dual-Institutional Study, G. Narayanasamy, A. P. Pyakuryal, S. Pandit, J. Vincent, C. Lee, P. Mavroidis, N. Papanikolaou, Mahesh Kudrimoti, T. T. Sio

Radiation Medicine Faculty Publications

In clinical practice, evaluation of clinical efficacy of treatment planning stems from the radiation oncologist's experience in accurately targeting tumors, while keeping minimal toxicity to various organs at risk (OAR) involved. A more objective, quantitative method may be raised by using radiobiological models. The purpose of this work is to evaluate the potential correlation of OAR-related toxicities to its radiobiologically estimated parameters in simultaneously integrated boost (SIB) intensity modulated radiation therapy (IMRT) plans of patients with head and neck tumors at two institutions. Lyman model for normal tissue complication probability (NTCP) and the Poisson model for tumor control probability (TCP) …

Sex Differences In Placental Epigenetic Regulation Of Leptin Hormone Are Associated With Elevated Maternal Gestational Weight Gain, Nicole E. Douthit, Nicki Aubuchon-Endsley Ph.D. (Mentor)

Idaho Conference on Undergraduate Research

In utero epigenetic factors affect health and development, though sex differences in epigenetic effects of prenatal maternal health may exist for placental hormones. Specifically, maternal prenatal obesity affects expression of placental leptin hormone genes, which play a unique role in metabolism and appetite. However, the effects of such expression on infant neurobehavioral development differ by offspring sex.

Therefore, we examined sex differences in the effects of maternal gestational weight on placental leptin gene methylation. Data (n=155) were taken from the Behavior and Mood in Mothers and Behavior in Infants Study. Maternal pre-pregnancy weight was self-reported, while delivery weight …

Investigations Into The Modification Of Dna By Doxorubicin Analogs, Hannah Kulm, Stephanie Torres, Chris Mallory, Kenneth Cornell (Mentor), Don Warner (Mentor)

Idaho Conference on Undergraduate Research

Doxorubicin (DOX) is an anthracycline chemotherapeutic that has seen widespread use to treat numerous cancer types. Its mechanism of action is still unclear, but is thought to include the intercalation of DNA, halting transcription and inducing apoptosis. Although DOX has shown strong antitumor activity, its usage is limited due to a dose-dependent onset of cumulative and irreversible life-threatening cardiac damage. Consequently, the harmful side effects necessitate the need for the production of new, less harmful anthracycline chemotherapeutics with greater effectiveness for the treatment of cancer. Three analogs of DOX (P-DOX, GPX-150 and GPX-160) have been synthesized and determined to have …

Photosynthetic Capacity Within The Phantom Gas Field Project, Traci L. Olson, Maria Pacioretty, Keith Reinhardt (Mentor)

Idaho Conference on Undergraduate Research

Anthropogenic noise has proven detrimental to organisms like bats, owls, and certain other species whose hunting or navigation success is affected by unnatural sound. However, few studies have quantified the effects of noise pollution across multiple trophic levels. Our study is quantifying the impacts of human noise on insect abundance and herbivory, and plant physiology, using experimental noise stations compared to quiet control sites in the sagebrush steppe southwest of Boise, Idaho. I am measuring variation in leaf chlorophyll fluorescence and Normalized Difference Vegetation Index (NDVI). Both of these measurements are indirect measurements of photosynthetic capacity. We hypothesized that shrubs …

The Utilization Of Polymerase Chain Reaction, Dna Barcoding And Bioinformatics In Identifying Plant Species, Lindee J. Triplett, Ryan Foo, Ronald W. Strohmeyer (Mentor)

Idaho Conference on Undergraduate Research

Bioinformatics and DNA barcoding is a process used to identify plants, animals, and fungi. DNA barcoding in plants utilizes a key variable region in the genome, the RuBisCo large subunit (RbcL) on Chloroplast DNA. Once the DNA is extracted, Polymerase Chain Reaction (PCR) amplifies that region and that sample is sent off for sequencing. Bioinformatics and DNA barcoding helps taxonomists determine the sequence of the RbcL gene as well as obtain a unique barcode that can be used to identify plants. Several plant species from our local campus were sequenced and identified using the previously described methods.

Human Impacts On Nitrogen And Phosphorus Concentrations In The North Sea, Craig Weatherhead

The Plymouth Student Scientist

This study evaluates the temporal and spatial variations in nutrient concentrations within the period of 1990-2011, with the aim to assess the effectiveness of legislative implementation and associated control measures within the period. Annual nutrient emission data were been obtained from OSPAR’s Joint Assessment Monitoring Programmes (JAMP’s) to provide values of riverine flow, direct discharge and atmospheric concentration. Temporal assessments of annual nutrient emissions were carried out on a European and national scale, using statistical analysis within periods of legislative change to assess the regional and sub-regional response to legislative implementation. Nutrient data were also obtained from the EEA database …

The Role Of Community Pharmacy-Based Vaccination In The Usa: Current Practice And Future Directions, Albert Bach, Jeffery A. Goad

Pharmacy Faculty Articles and Research

Community pharmacy-based provision of immunizations in the USA has become commonplace in the last few decades, with success in increasing rates of immunizations. Community pharmacy-based vaccination services are provided by pharmacists educated in the practice of immunization delivery and provide a convenient and accessible option for receiving immunizations. The pharmacist's role in immunization practice has been described as serving in the roles of educator, facilitator, and immunizer. With a majority of pharmacist-provided vaccinations occurring in the community pharmacy setting, there are many examples of community pharmacists serving in these immunization roles with successful outcomes. Different community pharmacies employ a number …

Is Trust Always Better Than Distrust? The Potential Value Of Distrust In Newer Virtual Teams Engaged In Short-Term Decision-Making, Paul Benjamin Lowry, Ryan M. Schuetzler, Justin Scott Giboney, Thomas A. Gregory

Information Systems and Quantitative Analysis Faculty Publications

The debate on the benefits of trust or distrust in groups has generated a substantial amount of research that points to the positive aspects of trust in groups, and generally characterizes distrust as a negative group phenomenon. Therefore, many researchers and practitioners assume that trust is inherently good and distrust is inherently bad. However, recent counterintuitive evidence obtained from face-to-face (FtF) groups indicates that the opposite might be true; trust can prove detrimental, and distrust instrumental, to decision-making in groups. By extending this argument to virtual teams (VTs), we examined the value of distrust for VTs completing routine and non-routine …

Origin And Evolution Of Petrocosmea (Gesneriaceae) Inferred From Both Dna Sequence And Novel Findings In Morphology With A Test Of Morphology-Based Hypotheses, Zhi-Jing Qiu, Yuan-Xue Lu, Chao-Qun Li, Yang Dong, James F. Smith, Yin-Zheng Wang

Biology Faculty Publications and Presentations

Background: Petrocosmea Oliver (Gesneriaceae) currently comprises 38 species with four non-nominate varieties, nearly all of which have been described solely from herbarium specimens. However, the dried specimens have obscured the full range of extremely diverse morphological variation that exists in the genus and has resulted in a poor subgeneric classification system that does not reflect the evolutionary history of this group. It is important to develop innovative methods to find new morphological traits and reexamine and reevaluate the traditionally used morphological data based on new hypothesis. In addition, Petrocosmea is a mid-sized genus but exhibits extreme diverse floral variants. This …

Pavement And Riparian Forest Shape The Bird Community Along An Urban River Corridor, Christopher J.W. Mcclure, Allison C. Korte, Julie A. Heath, Jesse R. Barber

Biology Faculty Publications and Presentations

Knowledge of habitat use by animals within urban-riparian corridors during the breeding season is important for conservation, yet remains understudied. We examined the bird community along an urban-riparian corridor through metropolitan Boise, Idaho and predicted that occupancy of individual species and species richness would be greater in forested areas than in urbanized areas. We surveyed birds throughout the summers of 2009 and 2010 and quantified the m² of each cover-type within 50-m, 100-m, and 200-m buffers surrounding each survey location using satellite imagery. Occupancy modeling revealed that eight of 14 species analyzed were positively associated with riparian forest, and …

Dynamic Tactile Information Is Sufficient For Precise Curvature Discrimination, Jacob R. Cheeseman

Masters Theses & Specialist Projects

Our tactile perceptual experiences occur when we interact, actively and passively, with environmental objects and surfaces. Previous research has demonstrated that active manual exploration enhances the tactile perception of object shape. Nevertheless, the factors that contribute to this enhancement are not well understood. The present study evaluated the ability of 14 older adults to discriminate curved surfaces by actively feeling objects with a single index finger and by passively feeling objects that moved relative to a restrained finger. The curvature discrimination thresholds obtained for passive-dynamic touch were significantly lower than those that occurred during active-dynamic touch. This result demonstrates that …

Keeping The Magic: Fursona Identity And Performance In The Furry Fandom, Jakob W. Maase

Masters Theses & Specialist Projects

The furry subculture (also known as the anthropomorphic fandom) creates identity through anthropomorphism and therianthropy. Anthropomorphism is the giving of human traits to the non-human. Therianthropy is the giving of animal traits to the human. Through play and creating art, these individuals of the furry subculture take on an anthropomorphic identity (what furries call a fursona) while bridging local and global groups through communication technologies. For this folklore project I conducted ethnographic field works interviews with the Bowling Green, Kentucky fur group. I also build off of the interviews project with an online furry role-play group as well as a …
