Regulation Of Renal Proximal Tubule Na-K-Atpase By Prostaglandins, Maryann Herman, Trivikram Rajkhowa, Facundo Cutuli, James E. Springate, Mary Taub

Biology Faculty/Staff Publications

Prostaglandins (PGs) play a number of roles in the kidney, including regulation of salt and water reabsorption. In this report, evidence was obtained for stimulatory effects of PGs on Na-K-ATPase in primary cultures of rabbit renal proximal tubule (RPT) cells. The results of our real-time PCR studies indicate that in primary RPTs the effects of PGE2, the major renal PG, are mediated by four classes of PGE (EP) receptors. The role of these EP receptors in the regulation of Na-K-ATPase was examined at the transcriptional level. Na-K-ATPase consists of a catalytic α-subunit encoded by the ATP1A1 gene, as well as …

The Northwest Forest Plan: Up To Our Neck In Owls?, Ashley N. Horvat

Honors Theses

Traversing across the vast Pacific Northwest with the Northern spotted owl (Strix occidentalis caurina), one would experience a dynamic landscape that ranged from areas shrouded with ancient forests, mountains dotted with dense young forests, large swathes of empty habitat from clearcuts, and corridors filled with canopies and a plethora of life. The once vibrant forests that blanketed the Pacific Northwest in an abundance of life and sheltered these rare owls in their canopies were threatened by the removal of these primordial giants in these forests. The wild salmon that journey in record numbers through the cold rivers and …

Cluster And Classification Analysis Of Fossil Invertebrates Within The Bird Spring Formation, Arrow Canyon, Nevada: Implications For Relative Rise And Fall Of Sea-Level, Scott L. Morris

Theses and Dissertations

Carbonate strata preserve indicators of local marine environments through time. Such indicators often include microfossils that have relatively unique conditions under which they can survive, including light, nutrients, salinity, and especially water temperature. As such, microfossils are environmental proxies. When these microfossils are preserved in the rock record, they constitute key components of depositional facies. Spence et al. (2004, 2007) has proposed several approaches for determining the facies of a given stratigraphic succession based upon these proxies. Cluster analysis can be used to determine microfossil groups that represent specific environmental conditions. Identifying which microfossil groups exist through time can indicate …

A Computer Vision Application To Accurately Estimate Object Distance, Kayton B. Parekh

Mathematics, Statistics, and Computer Science Honors Projects

Scientists have been working to create robots that perform manual work for years. However, creating machines that can navigate themselves and respond to their environment has proven to be difficult. One integral task to such research is to estimate the position of objects in the robot's visual field.

In this project we examine an implementation of computer vision depth perception. Our application uses color-based object tracking combined with model-based pose estimation to estimate the depth of specific objects in the view of our Pioneer 2 and Power Wheels robots. We use the Camshift algorithm for color-based object tracking, which uses …

Past And Projected Future Changes In Snowpack And Soil Frost At The Hubbard Brook Experimental Forest, New Hampshire, Usa, John L. Cambell, Scott V. Ollinger, Gerald N. Flerchinger, Haley Wicklein, Katharine Hayhoe, Amey S. Bailey

Faculty Publications

Long‐term data from the Hubbard Brook Experimental Forest in New Hampshire show that air temperature has increased by about 1 °C over the last half century. The warmer climate has caused significant declines in snow depth, snow water equivalent and snow cover duration. Paradoxically, it has been suggested that warmer air temperatures may result in colder soils and more soil frost, as warming leads to a reduction in snow cover insulating soils during winter. Hubbard Brook has one of the longest records of direct field measurements of soil frost in the United States. Historical records show no long‐term trends in …

Implication Of Gender Stereotypes For Public Policy, Sharon Smith

Theses and Dissertations

Stereotypes continue to be present and impact the assessment of women’s leadership effectiveness. Using a data set of senior executives in the public sector from The Leadership Circle multi-rater assessment tool, research supports the theory that gender influences how bosses rate their direct reports on leadership effectiveness. Survey data identifying leadership characteristics in the assessment as communal or agentic substantiate role congruence theory that women are still penalized for behaving contrary to the feminine stereotype. Role congruence theory seeks to explain the barriers that prevent women from rising into leadership positions. Representative bureaucracy explains the consequence in public policy when …

Atomic-Force-Microscope Indentation Of Alveolar Epithelial Type Ii Cells, Catherine Eileen Cozad

Electronic Theses and Dissertations Archive

Cozad, Catherine Eileen. M.S. The University of Memphis. May 2010. Atomic-Force-Microscope Indentation of Alveolar Epithelial Type II Cells. Major Professor: Esra Roan, Ph.D. Primary rat alveolar epithelial type II (ATII) cells dedifferentiate over time in culture into alveolar epithelial type I (ATI) cells. The mechanical characteristics of ATII cells measured as elastic modulus (E) could be time dependent in culture. An atomic force microscope was used to perform force indentation (F-δ) on the ATII cells, using pyramidal cantilevers with spring constant of 0.03 ± 0.01 N/m. Seven isolations of ATII cells were cultured; square regions inconfluent cultureswere studied by indentation …

The Effectiveness Of Function-Based Classroom Interventions Using Functional Behavior Assessments And An In-School Suspension Program, Clinton Smith

Electronic Theses and Dissertations Archive

Every day administrators and teachers issue increasing numbers of disciplinary referrals that document problematic behaviors in the classroom. When placed in in-school suspension (ISS) because of disciplinary reasons students lose valuable academic instruction time and their academic achievement is negatively impacted. ISS produces little, if any, meaningful behavior change at the expense of the academic achievement of students. Although the Individuals with Disabilities Education Improvement Act (2004) makes provisions for conducting functional behavior assessments (FBA) for students with disabilities, best practices would allow using the same process for at-risk students without disabilities who have behavioral issues in the classroom. Yet …

Species Of Coccidia (Apicomplexa: Eimeriidae) Infecting Pikas From Alaska, U.S.A. And Northeastern Siberia, Russia, A. J. Lynch, Donald W. Duszynski, Joseph A. Cook

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Eighty-eight fecal samples from 2 species of pika, Ochotona collaris and Ochotona hyperborea, collected in Alaska (N = 53) and Russia (N = 35), respectively, were examined for the presence of coccidia (Apicomplexa: Eimeriidae). Five oocyst morphotypes were observed. In O. collaris, we found Eimeria calentinei, Eimeria cryptobarretti, and Eimeria klondikensis, whereas in O. hyperborea, we found Eimeria banffensis, E. calentinei, E. cryptobarretti, E. klondikensis, and Isospora marquardti. This study represents new geographic records for all 5 coccidia and new host records for E. cryptobarretti and I. …

Fluctuations And Pattern Formation In Self-Propelled Particles, Shradha Mishra, Aparna Baskaran, M. Cristina Marchetti

Physics - All Scholarship

We consider a coarse-grained description of a system of self-propelled particles given by hydrodynamic equations for the density and polarization fields. We find that the ordered moving or flocking state of the system is unstable to spatial fluctuations beyond a threshold set by the self-propulsion velocity of the individual units. In this region, the system organizes itself into an inhomogeneous state of well-defined propagating stripes of flocking particles interspersed with low density disordered regions. Further, we find that even in the regime where the homogeneous flocking state is stable, the system exhibits large fluctuations in both density and orientational order. …

Partitioning Of Minimotifs Based On Function With Improved Prediction Accuracy, Sanguthevar Rajasekaran, Tian Mi, Jerlin Camilus Merlin, Aaron Oommen, Patrick R. Gradie, Martin R. Schiller

Life Sciences Faculty Research

Background

Minimotifs are short contiguous peptide sequences in proteins that are known to have a function in at least one other protein. One of the principal limitations in minimotif prediction is that false positives limit the usefulness of this approach. As a step toward resolving this problem we have built, implemented, and tested a new data-driven algorithm that reduces false-positive predictions.

Methodology/Principal Findings

Certain domains and minimotifs are known to be strongly associated with a known cellular process or molecular function. Therefore, we hypothesized that by restricting minimotif predictions to those where the minimotif containing protein and target protein have …

Mathematics, Computer Science & Statistics Faculty Publications

The basic unit of any nervous system is the neuron. Therefore, understanding the operation of nervous systems ultimately requires an inventory of their constituent neurons and synaptic connectivity, which form neural circuits. The presence of uniquely identifiable neurons or classes of neurons in many invertebrates has facilitated the construction of cellular-level connectivity diagrams that can be generalized across individuals within a species. Homologous neurons can also be recognized across species. Here we describe NeuronBank.org, a web-based tool that we are developing for cataloging, searching, and analyzing neuronal circuitry within and across species. Information from a single species is represented in …

Optimization And Evaluation Of A Proportional Derivative Controller For Planar Arm Movement, Kathleen M. Jagodnik, Antonie J. Van Den Bogert

Mechanical Engineering Faculty Publications

In most clinical applications of functional electrical stimulation (FES), the timing and amplitude of electrical stimuli have been controlled by open-loop pattern generators. The control of upper extremity reaching movements, however, will require feedback control to achieve the required precision. Here we present three controllers using proportional derivative (PD) feedback to stimulate six arm muscles, using two joint angle sensors. Controllers were first optimized and then evaluated on a computational arm model that includes musculoskeletal dynamics. Feedback gains were optimized by minimizing a weighted sum of position errors and muscle forces. Generalizability of the controllers was evaluated by performing movements …

Diet Reconstruction Of Bighorn Sheep (Ovis Canadensis) Using Stable Isotopes, Joshua M. Whitaker

Theses and Dissertations

We determined the diet contributions of grasses, forbs and shrubs for three herds of bighorn sheep along the Wasatch Front, Utah using stable isotope techniques and determined the electivity values for different forage species for four herds. Forbs were generally the most common forage eaten across all herds while shrubs were the least used forage resource. The Provo Peak and Mount Nebo herds used grasses, forbs and shrubs at proportions similar to other bighorn sheep populations across the west, while the Antelope Island herd used forbs at higher levels than any other local herd. Additionally, the herd on Antelope Island …
