Reef Fish And Coral Assemblages On Hospital Point And Near Bastimentos Island, Panama, Elaine Shen

Independent Study Project (ISP) Collection

Because worldwide declines coral reef health are of major concern, studying coral reefs through the lens of conservation efforts at local scales is essential for determining and monitoring effective policy measures. In the Bocas del Toro Archipelago, there are conflicts of interest between exploitative rapid tourism development, overfishing practices, and national efforts to conserve the local marine biodiversity. Coral and reef fish species abundance richness, diversity, evenness, and similarity were measured to see how coral and reef fish assemblages changed between protected and unprotected areas. A total of 329 fish and 322.5 square meters of benthos were analyzed using underwater …

Dissertations

This dissertation’s focus is at the intersection of study abroad, impact assessment, and a population of gifted and talented students at a specialized, residential high school called The Gatton Academy. A summative impact evaluation was conducted to assess effects of Gatton Academy study abroad programs on student participants’ perceptions of peer belongingness, mentor belongingness, and personal growth and development, as well as to compare differences among three different program models being employed by the school. The three program models studied included a Non-Credit program, a Faculty-led Field-Study, and a Faculty-led Traditional program. The research was conducted amidst documented calls for …

Examining Teacher Practices Related To Student-To-Student Discourse In The Middle School Classroom, April Dawn Craft

Dissertations

As schools strive to develop 21st century learners equipped with skills in critical thinking and communication, the use of research-based teaching strategies, such as student-to-student discourse, is a necessary component of highly effective instruction. Research has shown that the way in which a teacher facilitates discourse in the classroom has a powerful impact on student learning and achievement. This case study examines the beliefs and instructional practices of a middle grades science teacher as they pertain to the use of student-to-student discourse, or students' use of a set of common language patterns in order to construct meaning or to develop …

Orm Expression Alters Sphingolipid Homeostasis And Differentially Affects Ceramide Synthase Activity, Athen N. Kimberlin, Gongshe Han, Kyle D. Luttgeharm, Ming Chen, Rebecca E. Cahoon, Julie M. Stone, Jennifer E. Markham, Teresa M. Dunn, Edgar B. Cahoon

Center for Plant Science Innovation: Faculty Publications

Sphingolipid synthesis is tightly regulated in eukaryotes. This regulation in plants ensures sufficient sphingolipids to support growth while limiting the accumulation of sphingolipid metabolites that induce programmed cell death. Serine palmitoyltransferase (SPT) catalyzes the first step in sphingolipid biosynthesis and is considered the primary sphingolipid homeostatic regulatory point. In this report, Arabidopsis (Arabidopsis thaliana) putative SPT regulatory proteins, orosomucoidlike proteins AtORM1 and AtORM2, were found to interact physically with Arabidopsis SPT and to suppress SPT activity when coexpressed with Arabidopsis SPT subunits long-chain base1 (LCB1) and LCB2 and the small subunit of SPT in a yeast ( …

Chemical Activation Of A Food Deprivation Signal Extends Lifespan., Mark Lucanic, Theo Garrett, Ivan Yu, Fernando Calahorro, Azar Asadi Shahmirzadi, Aaron Miller, Matthew S Gill, Robert E. Hughes, Lindy Holden-Dye, Gordon J. Lithgow

Natural Sciences and Mathematics | Student Professional Publications

Model organisms subject to dietary restriction (DR) generally live longer. Accompanying this lifespan extension are improvements in overall health, based on multiple metrics. This indicates that pharmacological treatments that mimic the effects of DR could improve health in humans. To find new chemical structures that extend lifespan, we screened 30 000 synthetic, diverse drug-like chemicals in Caenorhabditis elegans and identified several structurally related compounds that acted through DR mechanisms. The most potent of these NP1 impinges upon a food perception pathway by promoting glutamate signaling in the pharynx. This results in the overriding of a GPCR pathway involved in the …

The Benefits Of Attending The Annual Biomedical Research Conference For Minority Students (Abrcms): The Role Of Research Confidence, Bettina J. Casad, Amy L. Chang, Christine M. Pribbenow

Psychology Faculty Works

The Annual Biomedical Research Conference for Minority Students (ABRCMS) is designed to support undergraduate students’ professional development as future scientists. Juniors, seniors, and postbaccalaureates who attended ABRCMS during 2008–2011 were emailed a link to an online questionnaire in which they reported their experiences at the conference. Attendees reported many ABRCMS-provided benefits. Frequency of attending or presenting at ABRCMS is positively related to science self-efficacy, research confidence, sense of belonging in science, and intentions to pursue a research degree in graduate school. Increased research confidence predicts graduate school plans and intentions for a research career in science; however, men were slightly …

Characterizing The Reproduction Number Of Epidemics With Early Subexponential Growth Dynamics., Gerardo Chowell, Cécile Viboud, Lone Simonsen, Seyed M Moghadas

Global Health Faculty Publications

Early estimates of the transmission potential of emerging and re-emerging infections are increasingly used to inform public health authorities on the level of risk posed by outbreaks. Existing methods to estimate the reproduction number generally assume exponential growth in case incidence in the first few disease generations, before susceptible depletion sets in. In reality, outbreaks can display subexponential (i.e. polynomial) growth in the first few disease generations, owing to clustering in contact patterns, spatial effects, inhomogeneous mixing, reactive behaviour changes or other mechanisms. Here, we introduce the generalized growth model to characterize the early growth profile of outbreaks and estimate …

Feasibility Of The Use Of Neutron Activation Analysis Techniques In An Underwater Environment, Michael D. Chick

Masters Theses & Specialist Projects

Elements when bombarded with neutrons emit a gamma ray that is characteristic of the isotope that underwent a neutron induced nuclear reaction; this is known as neutron activation. The characteristic gamma energy of an isotope can then be detected and recorded. One can then analyze the gamma energies captured and determine the elemental makeup of the sample. This form of analysis can be used in an underwater environment making it potentially a valuable tool for agencies tasked with maritime security of ports and waterways, or clean-up operations. This thesis will focus on the feasibility of neutron interrogation using pulsed fast/thermal …

The Effects Of Sulfuric Acid Deposition On The Growth And Development Of Pond Breeding Salamanders In The Genus Ambystoma, Kenneth J. Anderson

Masters Theses & Specialist Projects

In terrestrial habitats with a history of mining activity and previous or ongoing reclamation efforts, understanding the effects of acidification on the ecology of amphibians is an important part of the restoration process and the conservation of local amphibian populations. Pond-breeding amphibians spend much of their post metamorphic life history in direct contact with the soil in upland habitat adjacent to aquatic breeding sites. I reared recently metamorphosed marbled salamanders (Ambystoma opacum) to evaluate the role of soil acidity on determinants of fitness such as growth and survival. My results indicate that a substrate of pH 4 was lethal to …

Metal-Organic Hybrid Nanocomposites For Energy Harvesting Applications, Thulitha Madawa Abeywickrama

Masters Theses & Specialist Projects

Various synthetic methods have been developed to produce metal nanostructures including copper and iron nanostructures. Modification of nanoparticle surface to enhance their characteristic properties through surface functionalization with organic ligands ranging from small molecules to polymeric materials including organic semiconducting polymers is a key interest in nanoscience. However, most of the synthetic methods developed in the past depend widely on non-aqueous solvents, toxic reducing agents, and high temperature and high-pressure conditions. Therefore, to produce metal nanostructures and their nanocomposites with a simpler and greener method is indeed necessary and desirable for their nano-scale applications. Hence the objective of this thesis …

Development Of Dihydrochalcone Functionalized Gold Nanoparticles For Augmented Antineoplastic Activity, Jason N. Payne

Masters Theses & Specialist Projects

Phloridzin, an antidiabetic and antineoplastic agent usually found in fruit trees, is a dihydrochalcone constituent that has a clinical/pharmaceutical significance as a sodiumglucose linked transport 2 (SGLT2) inhibitor. Phloridzin never experienced widespread clinical usage in the pharmaceutical market due to its side effects and poor bioavailability when compared to other antidiabetic therapeutics. The poor bioavailability is primarily attributed to the degradation of the glycosidic bond of the phloridzin, resulting in the formation of phloretin, the aglycone of phloridzin and glucose. While phloretin displays a reduced capacity of SGLT2 inhibition, this nutraceutical shows enhanced antineoplastic activity in comparison to phloridzin. Gold …

Visible-Light Generation Of High-Valent Metal-Oxo Intermediates And A Biomimetic Oxidation Catalyzed By Manganese Porphyrins With Iodobenzene Diacetate, Ka Wai Kwong

Masters Theses & Specialist Projects

High-valent iron-oxo intermediates play central roles as active oxidants in enzymatic and synthetic catalytic oxidations. Many transition metal catalysts are designed for biomimetic studies of the predominant oxidation catalysts in Nature, the cytochrome P450 enzymes.

In this work, a new photochemical method to generate high-valent iron-oxo porphyrin models was discovered. As controlled by the electronic nature of porphyrin ligands, iron(IV)-oxo porphyrin radical cations (Compound I model) and iron(IV)-oxo porphyrin derivatives (Compound II model) were produced. These observations indicate that the photochemical reactions involve a heterolytic cleavage of O-Br in precursors to give a putative iron(V)-oxo intermediate, which might relax to …

These data were collected in the northern-most reaches of the Andes Mountains in the Piedras Blancas páramo, Sierra de La Culata National Park, Venezuela, during January-March 2014 (dry season). Sites were located in the high Andean páramo (superpáramo), between 4250m-4350m, with slopes of 15-25 degrees, and on northeast facing aspects. We sampled three sites in a 5 km area: Rio Azul (8.8866, -70.8685), Avenida (8.8847, -70.8666), and Gloria (8.8928, -70.8714). Life in this region is subject to harsh and dynamic tropical alpine conditions.This region is the driest in Venezuela’s high alpine, with an annual precipitation of 860 mm (Pico …

Preterm Neonatal Lateral Ventricle Volume From Three-Dimensional Ultrasound Is Not Strongly Correlated To Two-Dimensional Ultrasound Measurements, Jessica Kishimoto, Sandrine De Ribaupierre, Fateme Salehi, Walter Romano, David S. C. Lee, Aaron Fenster

Anatomy and Cell Biology Publications

The aim of this study is to compare longitudinal two-dimensional (2-D) and three-dimensional (3-D) ultrasound (US) estimates of ventricle size in preterm neonates with posthemorrhagic ventricular dilatation (PHVD) using quantitative measurements of the lateral ventricles. Cranial 2-D US and 3-D US images were acquired from neonatal patients with diagnosed PHVD within 10 min of each other one to two times per week and analyzed offline. Ventricle index, anterior horn width, third ventricle width, and thalamo-occipital distance were measured on the 2-D images and ventricle volume (VV) was measured from 3-D US images. Changes in the measurements between successive image sets …

Can We Predict The Effects Of Multiple Stressors On Insects In A Changing Climate?, Sirpa Kaunisto, Laura V Ferguson, Brent J Sinclair

Biology Publications

The responses of insects to climate change will depend on their responses to abiotic and biotic stressors in combination. We surveyed the literature, and although synergistic stressor interactions appear common among insects, the thin taxonomic spread of existing data means that more multi-stressor studies and new approaches are needed. We need to move beyond descriptions of the effects of multiple stressors to a mechanistic, predictive understanding. Further, we must identify which stressor interactions, and species' responses to them, are sufficiently generalizable (i.e. most or all species respond similarly to the same stressor combination), and thus predictable (for new combinations of …

Generalized Partial Directed Coherence And Centrality Measures In Brain Networks For Epileptogenic Focus Localization, Joshua Aaron Adkinson

Doctoral Dissertations

Accurate epileptogenic focus localization is required prior to surgical resection of brain tissue for treatment of patients with intractable temporal lobe epilepsy, a clinical need that is partially fulfilled to date through a subjective, and at times inconclusive, evaluation of the recorded electroencephalogram (EEG). Using brain connectivity analysis, patterns of causal interactions between brain regions were derived from multichannel EEG of 127 seizures in nine patients with focal, temporal lobe epilepsy (TLE). The statistically significant directed interactions in the reconstructed brain networks were estimated from three second intracranial multi-electrode EEG segments using the Generalized Partial Directed Coherence (GPDC) and validated …
