The Effects Of Neonatal Handling On Adrenocortical Responsiveness, Morphological Development And Corticosterone Binding Globulin In Nestling American Kestrels (Falco Sparverius), Buddy A. Whitman, Creagh W. Breuner, Alfred M. Dufty

Biology Faculty Publications and Presentations

Early developmental experiences play an important role in development of the adult phenotype. We investigated the effects of neonatal handling on the hypothalamic-pituitary-adrenal axis in a free-living avian species, the American kestrel (Falco sparverius). In the handled group (H), kestrel chicks were handled for 15 min/day from hatching until 26 days of age, after which time blood samples were collected for analysis of adrenal responsiveness and corticosterone binding globulin (CBG) levels. The non-handled control group (NH) was left undisturbed until 26 days of age when blood samples were collected and analyzed as above. Handled and NH kestrels did not differ …

Characterization Of A Dual Acoustic Receiver System For Measuring Range And Bearing To Acoustic Tags, Victoria Campana, Justin Knight

Computer Engineering

Experiements were performed to determine the effectiveness of the Lotek RT-A Hydrophone system and if it could provide the data necessary for a particle filter to determine the location of a shark. Over the period of a few months, we tested off the Cal Poly Pier at set GPS coordinates to characterize how accurately the Lotek System can determine range and orientation. Ranges from 0-500 meters were tested with the Lotek system being in a stationary position and Lotek receiver tag being put at specified GPS coordinates. The two hydrophone rigging was then rotated a full 360 degrees to gauge …

Beyond The Language Program Model: The Importance Of Student Identity For The English Language Learner, Arthi Rao

College of Education Theses and Dissertations

This ethnographic dissertation study focuses on life in fourth grade classrooms, examining how sociocultural experiences and influences in the local learning environment impact native Spanish-speaking English language learners’ (ELL) identities, and subsequently how students perceive their schooling experience and language practices. Connections are made between their learning and experiences that occur in their classrooms and schools at large, specifically through language of instruction and schooling practices, and how ELLs identify themselves as individuals and members of society. This qualitative research looks at ELLs in transitional bilingual and dual language classroom contexts through the frameworks of sociocultural theory and language as …

Stress-Dependent Impairment Of Passive-Avoidance Memory By Propranolol Or Naloxone, Allen M. Schneider, Peter E. Simson , '78, Ranga Keshani Atapattu , '08, Lynn G. Kirby , '89

Psychology Faculty Works

Previous work has shown that the effect of opioid-receptor blockade on memory modulation is critically dependent upon the intensity of stress. The current study determined the effect of adrenergic-receptor blockade on memory modulation under varied levels of stress and then compared the effect of adrenergic-receptor blockade under intense stress to that of a) opioid-receptor blockade and b) concurrent opioid- and adrenergic-receptor blockade. In the first experiment, the β-adrenergic-receptor blocker propranolol impaired retention in the passive-avoidance procedure when administered immediately after exposure to intense stress (passive-avoidance training followed by swim stress) but not mild stress (passive-avoidance training alone). In the second …

Who Am I And Who Do You Want Me To Be? Effectively Defining A Lesbian, Gay, Bisexual, And Transgender Social Group In Asylum Applications, Keith Southam

Chicago-Kent Law Review

Asylum law provides an area within immigration law that is unexpectedly friendly to lesbians, gay men, bisexuals, and transgender persons. Persons who suffer persecution on account of "membership in a particular social group" are eligible to live and work in the United States. This encompasses lesbians, gay men, bisexuals, and transgender persons who suffer persecution. However, United States law does not clearly define applicable standards in this area. As a result, different adjudicators in the asylum process focus on different methodological approaches and sometimes inject bias into the process. In addition, because the terms "lesbian," "gay," "bisexual," and "transgender" are …

Potential Water Quality Changes Due To Corn Expansion In The Upper Mississippi River Basin, Silvia Secchi, Philip W Gassman, Manoj Jha, Lyubov Kurkalova, Catherine L Kling

Articles

While biofuels may yield renewable fuel benefits, there could be downsides in terms of water quality and other environmental stressors, particularly if corn is relied upon exclusively as the feedstock. The consequences of increased corn production will depend importantly on where (and how) the additional corn is grown, which, in turn, depends on the characteristics of land and its associated profitability. Previous work has relied on rules of thumb for allocating land to increased acreage based on historical land use or other heuristics. Here, we advance our understanding of these phenomena by describing a modeling system that links an economics-driven …

A Novel Exercise Device For Users In Wheelchairs: A Study Of Abdominal Muscle Activation, Rebecca Jo Campbell

Master's Theses

This study evaluates the use of a wheelchair balance board. The balance board was created as a sensory stimulation tool for users with various disabilities. It was originally designed to create vestibular stimulation for the person after they were loaded on.  This study was used as a way to test if the balance board could be used for other things such as physical therapy and exercise.  Ten able-bodied individuals were used to show the functionality of the device.  They were asked to perform six different abdominal exercises while the muscle activity of their rectus abdominis and external obliques was measured …

Measuring The Nanoindentation Properties Of Alendronate-Time Treated Canine Cortical, Folorunso Ashaolu

Master's Theses

This study examines the nanoindentation (energy inclusive) properties of 0.2 mg/kg alendronate treated ribs at one and three years against a vehicle treated control in a fresh-frozen, non-cold-mounted, condition.  This was to verify if the tissue-level properties for 0.2 ALN treated beagles would increase because of an increased level of mineralization despite a microdamage increase.

A total of twelve (12) skeletally mature (1–2 years old) female beagle dogs were treated daily for three years and one year with oral doses of vehicle (VEH, 1 mL/kg saline) or alendronate (ALN, 0.2 Merck, Rahway, NJ). The 0.2 mg dose corresponds, on a …

Ischemia Impairs Vasodilation In Skeletal Muscle Resistance Artery, Kyle Remington Struthers

Master's Theses

Functional vasodilation in arterioles is impaired with chronic ischemia. We sought to examine the impact of chronic ischemia and age on skeletal muscle resistance artery function. To examine the impact of chronic ischemia, the femoral artery was resected from young (2-3mo) and adult (6-7mo) mice and the profunda femoris artery diameter was measured at rest and following gracilis muscle contraction 14 days later using intravital microscopy. Functional vasodilation was significantly impaired in ischemic mice (14.4±4.6% vs. 137.8±14.3%, p<0.0001 n=8) and non-ischemic adult mice (103.0±9.4% vs. 137.8±14.3%, p=0.05 n=10). In order to analyze the cellular mechanisms of the impairment, a protocol was developed to apply pharmacological agents to the experimental preparation while maintaining tissue homeostasis. Endothelial and smooth muscle dependent vasodilation were impaired with ischemia, 39.6 ± 13.6% vs. 80.5 ± 11.4% and 43.0 ± 11.7% vs. 85.1 ± 10.5%, respectively. From this data, it can be supported that smooth muscle dysfunction is the reason for the observed impairment in arterial vasodilation.

Factors Influencing Ectoparasitism On Western Fence Lizards (Sceloporus Occidentalis): Host Sex, Testosterone, Reproductive Condition, And Behavior, Nicholas B. Pollock

Master's Theses

Host-parasite relationships are one of the most common symbiotic relationships present in a diverse array of ecosystems. There are numerous factors that impact the dynamics of these relationships. Major factors that can influence the degree of parasitism include host sex, hormonal state, reproductive condition, and behavior. It has been observed in several vertebrate taxa that males have higher ectoparasite intensities than females and males with increased testosterone have increased ectoparasite intensities. One potential reason for these observations is that testosterone concentrations are elevated in males, particularly during the breeding season, and when circulating concentrations increase males become more vulnerable to …

Learning To Fly: The Untold Story Of How The Wright Brothers Learned To Be The World's First Aeronautical Engineers, Daniel Lawrence Slusser

Master's Theses

This paper examines the education, events, and experiences of the Wright brothers in order to determine how they developed the necessary skills to engineer the first viable aircraft. Without high school diplomas, and with no advanced formal education, the Wright brothers were able to develop aircraft that far exceeded the capabilities of aircraft designed and built by professional engineers that had worked on the problem of flight for much longer and with substantially larger research budgets. I argue that the Wright brothers’ success resulted from their experiences in the printing and bicycle industries as well as their formal and informal …

Iron-Sulfur Proteins Are The Major Source Of Protein-Bound Dinitrosyl Iron Complexes Formed In Escherichia Coli Cells Under Nitric Oxide Stress, Aaron P. Landry, Xuewu Duan, Hao Huang, Huangen Ding

Faculty Publications

Protein-bound dinitrosyl iron complexes (DNICs) have been observed in prokaryotic and eukaryotic cells under nitric oxide (NO) stress. The identity of proteins that bind DNICs, however, still remains elusive. Here we demonstrate that iron-sulfur proteins are the major source of protein-bound DNICs formed in Escherichia coli cells under NO stress. Expression of recombinant iron-sulfur proteins, but not proteins without iron-sulfur clusters, almost doubles the amount of protein-bound DNICs formed in E. coli cells after NO exposure. Purification of recombinant proteins from the NO-exposed E. coli cells further confirms that iron-sulfur proteins, but not proteins without iron-sulfur clusters, are modified, forming …

Branchless Trichomes Links Cell Shape And Cell Cycle Control In Arabidopsis Trichomes, Remmy Kasili, Cho Chun Huang, Jason D. Walker, L. Alice Simmons, Jing Zhou, Chris Faulk, Martin Hülskamp, John C. Larkin

Faculty Publications

Endoreplication, also called endoreduplication, is a modified cell cycle in which DNA is repeatedly replicated without subsequent cell division. Endoreplication is often associated with increased cell size and specialized cell shapes, but the mechanism coordinating DNA content with shape and size remains obscure. Here we identify the product of the BRANCHLESS TRICHOMES (BLT) gene, a protein of hitherto unknown function that has been conserved throughout angiosperm evolution, as a link in coordinating cell shape and nuclear DNA content in endoreplicated Arabidopsis trichomes. Loss-of-function mutations in BLT were found to enhance the multicellular trichome phenotype of mutants in the SIAMESE (SIM) …

Vesicular Stomatitis Virus-Simian Retrovirus Type 2 Vaccine Protects Macaques From Detectable Infection And B-Cell Destruction, Rajeev Gautam, Arun Iyer, Meredith Hunter, Arpita Das, Tessa Williams, Jason Dufour, Cristian Apetrei, K. Gus Kousoulas, Preston A. Marx

Faculty Publications

Natural infection with simian retrovirus (SRV) has long been recognized in rhesus macaques (RMs) and may result in an AIDS-like disease. Importantly, SRV infections persist as a problem in recently imported macaques. Therefore, there is a clear need to control SRV spread in macaque colonies. We developed a recombinant vesicular stomatitis virus (VSV)-SRV vaccine consisting of replication-competent hybrid VSVs that express SRV gag and env in separate vectors. The goal of this study was to assess the immunogenicity and protective efficacy of the VSV-SRV serotype 2 vaccine prime-boost approach in RMs. The VSV-SRV vector (expressing either SRV gag or env) …

Reading Te Leaves: New Approaches To The Identification Of Transposable Element Insertions, David A. Ray, Mark A. Batzer

Faculty Publications

Transposable elements (TEs) are a tremendous source of genome instability and genetic variation. Of particular interest to investigators of human biology and human evolution are retrotransposon insertions that are recent and/or polymorphic in the human population. As a consequence, the ability to assay large numbers of polymorphic TEs in a given genome is valuable. Five recent manuscripts each propose methods to scan whole human genomes to identify, map, and, in some cases, genotype polymorphic retrotransposon insertions in multiple human genomes simultaneously. These technologies promise to revolutionize our ability to analyze human genomes for TE-based variation important to studies of human …

Host Specificity Of Anthonomus Tenebrosus (Coleoptera: Curculionidae), A Potential Biological Control Agent Of Tropical Soda Apple (Solanaceae) In Florida, J. Medal, N. Bustamante, E. Bredow, H. Pedrosa, W. Overholt, R. Díaz, J. Cuda

Life History Benefits Of Residency In A Partially Migrating Pond-Breeding Amphibian, Kristine L. Grayson, Larissa L. Bailey, Henry M. Wilbur

Biology Faculty Publications

Species with partial migration, where a portion of a population migrates and the other remains residential, provide the opportunity to evaluate conditions for migration and test mechanisms influencing migratory decisions. We conducted a five-year study of two populations of red-spotted newts (Notophthalmus viridescens), composed of individuals that either remain as residents in the breeding pond over the winter or migrate to the terrestrial habitat. We used multistate mark-recapture methods to (1) test for differences in survival probability between migrants and residents, (2) determine if migrants breed every year or skip opportunities for reproduction, and (3) estimate the frequency …
