Chemical Isolation From Plant Endophytes, David Dahl, Dr. Steven Wood

Journal of Undergraduate Research

The major research that I have worked with is on the extraction of biologically active compounds from plant endophytes native to the west desert of Utah and high altitude Paramo of Ecuador. For a year I have been working the Department of Chemistry and Biochemistry’s Natural Product Research Group under Dr. Noel Owen and Dr. Steven Wood. I planned and am executing a project that combines several different disciplines; anthropology, botany, and chemistry.

Relative Binding Affinity Of Non-Occupied And Single-Ion-Occupied Acetylcholinesterase With Acetylcholine, Scott Hollingshaus, Dr. James P. Lewis

Journal of Undergraduate Research

Trans-membrane channels are the highway mechanisms of biological cells. Through these channels, cells transfer information in the form of ions and other molecules. These transferred materials are called permeating ions. It is well known that most channels work on the principles of size, shape, and charge. Charged channels allow permeating ions of the opposite charge and appropriate shape to pass, while similarly charged ions cannot pass. However, the fluid inside and outside a cell contains many atomic ions, such as sodium (Na+) ions. Because these atomic ions are both small and charged they are able to fit through many different …

Engineering Small Molecule-Dependent Tools For The Study Of Protein Function In Vivo, Jonathan Dewey, Dr. Allen R. Buskirk

Journal of Undergraduate Research

Analyzing the function of newly discovered genes and the proteins that they encode is crucial to the advancement of genetics, cell and molecular biology, and medicine. Scientists have implemented various methods to study individual proteins within a cell, including genetic and small-molecule dependent approaches. Our goal is to combine the generality of genetic manipulation with the time-sensitivity of small-molecule dependence to create tools to study the function of Hedgehog pathway proteins and validate them as drug targets.

Heart Rate Variability As A Moderator Of Trauma Writing Outcomes, Alison Eonta

Theses and Dissertations

Writing about personal traumatic experiences is associated with beneficial effects on physical and psychological symptoms compared with writing about emotionally neutral events. However, not everyone benefits from trauma writing to the same extent. The present study hypothesized that the effectiveness of trauma writing may be moderated by emotion regulation, as indexed by respiratory sinus arrhythmia (RSA). Research also shows that greater physiological reactivity is predictive of better trauma writing outcomes. Given the importance of physiological output in emotional processing, response training was developed and found to increase appropriate physiological reactivity. Because higher RSA is thought to indicate a more flexible …

A Hypochondriac Investigates The Evolution Of Medicine, Natalie S. Sherif

Blogging the Library

This exhibit will open to the public in February 2014, but until then I have my work cut out for me. I am currently researching various aspects of medical history spanning from the mid-1800s, through the Civil War, to WWI. Thus far I have read accounts of women volunteers during the American Civil War, important changes that went into effect during WWI, and an overly detailed description on how to perform tooth extractions according to the latest science of the 1860s.

Size-Based Separation Of Bioparticles Using Planar Nanofluidic Devices, Jie Xuan

Theses and Dissertations

Nanofluidic devices are structures having at least one dimension in the submicron range, which is of the same order of magnitude as the sizes of biomolecules and bioparticles such as proteins and viruses. As a result, size-selective separations are important applications for nanofluidics. Well-defined micro or nano device structures fabricated via micromachining have greatly reduced sample consumption and enabled separations in a parallel fashion, promising significant speed and resolution advantages over conventional size separation techniques, such as gel electrophoresis and size exclusion chromatography. In collaboration with others, I have developed a size separation method using nanofluidic devices consisting of an …

Cytotoxicity Of Traditional Medicinal Plants Of Ghana, Stephanie Henderson, Dr. Gary M. Booth

Journal of Undergraduate Research

Medicinal plants are the oldest known health-care products in the world (WHO, 1996), and according to the World Health Organization, 80% of the population in Africa still use traditional medicines for primary health care (WHO, 2003). The situation in Ghana is particularly significant. In the Upper Region of Ghana, a population of over 1.2 million, there is one traditional healer to approximately 490 people, as opposed to one biomedical physician to every 66,667 people (Boye and Ampofo, 1987).

Blood Protein Isotopic Investigation, Michael J. Gravett, Kent Hatch

Journal of Undergraduate Research

Stable isotope ratios have been used for a variety of purposes in the biological sciences. These ratios have been used by plant ecologists to asses the photosynthetic mode, to measure water balance, and to trace nitrogen sources (Gannes, 1997). They have been used by animal ecologists to determine trophic relationships in food webs, to discriminate between animals that live in different biomes, to trace migratory animals, to follow nutrients through the body, and to undertake dietary reconstruction of both current and extinct species (Bearhop, 2002).

Rates Of Carbon And Nitrogen Stable Isotope Turnover In Fin Tissues Of Gambusia Affinis, Michael Bingham, Dr. Jeff Bullock

Journal of Undergraduate Research

The principle objectives of this research analysis were to determine the uptake and turnover rates of carbon and nitrogen stable isotopes in fish and to establish if this isotope verification procedure is possible by testing tissue samples of their fins. This investigation is separated into two main experiments: first, the stable isotope incorporation in the new growth of fin tissue, and second, the rate of stable isotope turnover in the old growth of fin tissue. Both experiments of this study were done with Gambusia affinis, a species of fish better know as mosquito fish.

Developing A New Fluctuating-Charge Force Field For Charmm, Soren Harward, David Busath

Journal of Undergraduate Research

Molecular Dynamics (hereafter abbreviated MD) is a method of simulating on a computer the behavior of molecules. For over twenty years, it had been a valuable tool that has allowed chemists and physicists to observe chemical interactions that would are difficult or impossible to measure with standard laboratory equipment. The rapid growth of computing power has made feasible simulations of larger and larger systems, so that now biologists can use MD to study the complex chemistry of living organisms.

Cruisin’ In The Bat-Mobile: Coevolution Of S-Symbiont Arsenophonus Spp. In Batflies (Diptera: Streblidae), Richard E. Trowbridge, Dr. Michael F. Whiting

Journal of Undergraduate Research

Symbiotic relationships between bacteria and insect hosts are common, with more than ten percent of insect species relying upon intracellular bacteria for their development and survival (Braendle 2003). These symbionts can stem from an obligatory association [primary (P-) endosymbionts], involving a number of properties (e.g. localization within special host cells; close concordance of the evolutionary trees of endosymbiont and host species). Besides P-endosymbionts, most bacteria contain a heterogeneous assemblage of bacteria called secondary (S-) endosymbionts. Usually, evolutionary trees of S-endosymbionts show little congruence to host trees, which is often interpreted as the result of independent horizontal transmissions. However, some evidence …

Do Inquiry, Constructivist Based Biology Laboratories Affect The Confidence And Attitude Of Preservice Elementary Education Teachers Toward Teaching Science In Their Classrooms?, Heddie L. Richard, Dr. Larry St. Clair

Journal of Undergraduate Research

Integrative Biology 101 is an optional course for preservice elementary education students to improve their science teaching skills. The format of the course allows each student the option to teach a science lesson and participate in a lab directed by the teacher’s assistant (T.A). Each lab follows a ‘cookbook’ style method. The T.A. gives the directions and explains the findings. The purpose of my research was to determine what science teaching methods improved the pre-service elementary school teachers’ attitude and confidence level.

Erythrocyte Shape Change And Vesicle Release With Methyl-Beta-Cyclodextrin, Jeremy Fairbourn, Dr. John Bell

Journal of Undergraduate Research

The study of membrane properties has direct applications in many branches of science. These properties influence the shape and behavior of the cell. With respect to erythrocytes, the membrane becomes susceptible to the action of secretory Phospholipase A2 (sPLA2) following treatment with ionophores such as ionomycin. The changes produced by ionomycin are experimental analogs to occurrences in the body. The normal actions of the immune system and metabolism cause changes to the cells such that apoptosis is eventually the endpoint of the cell.

Influenza A Virus M2 Protein Selectivity And Permeability Of Ammonium Ions At Varying Ph, Jared Kevin Pearson, David D. Busath

Journal of Undergraduate Research

The M2 protein inside the Influenza A virus capsid is vital to the virus’ replication. When the virus enters a cell, the M2 protein forms ion channels that allow the viral RNA to dissociate from stabilizing proteins, enter the host cell nucleus, and replicate. Blocking the formation of these ion channels, or disabling M2 protein ion transport therefore is an important area of research; inactivating the channel will prevent Influenza A replication.
