Investigating The Cause Of Unique Mechanical Behavior In Platinum Alloy Guidewire Tips, Evan Borgeson, Alfred Rosen

Materials Engineering

The platinum alloy used by Abbott Vascular in guidewire tips exhibits a yielding behavior characterized by an abrupt transition from elastic to plastic zones and high ductility. This yielding behavior was hypothesized to be a result of one of three structural phenomena: ordering, solute strain aging, or interstitial strain aging. To test for these strengthening mechanisms in the wire, X-ray diffraction analysis, heat treatments, and tensile testing were completed. The wire has a diameter of 0.0025 inches and was supplied in two forms, the final stress relieved state, and as-drawn from the production line. Heat treatments were performed at 130 …

The Effect Of Osm On Mc3t3-E1 Osteoblastic Cells In Simulated Microgravity With Radiation, Jake Goyden, Ken Tawara, Danielle Hedeen, Jeffrey S. Willey, Julia Thom Oxford, Cheryl L. Jorcyk

Biomedical Research Institute Publications and Presentations

Bone deterioration is a challenge in long-term spaceflight with significant connections to patients experiencing disuse bone loss. Prolonged unloading and radiation exposure, defining characteristics of space travel, have both been associated with changes in inflammatory signaling via IL-6 class cytokines in bone. While there is also evidence for perturbed IL-6 class signaling in spaceflight, there has been scant examination of the connections between microgravity, radiation, and inflammatory stimuli in bone. Our lab and others have shown that the IL-6 class cytokine oncostatin M (OSM) is an important regulator of bone remodeling. We hypothesize that simulated microgravity alters osteoblast OSM signaling, …

Chapter Eight: Ethnoarchaeology Of Foraging And The Case Of Vanishing Agriculturalists In The Amazon Basin, Pei-Lin Yu

Anthropology Faculty Publications and Presentations

Debates about ancient Amazonian social organization have evaluated characterizations from a range of sources that include ethnographically documented foraging societies and archaeological discoveries suggestive of sedentized agriculturists. This study uses qualitative ethnoarchaeological data about foraging and small-scale horticulture among the Pumé of Venezuela, and Lewis Binford’s quantified database of foraging groups and environmental parameters, to develop a testable model that predicts the conditions under which Amazon Basin foragers would (or would not) intensify subsistence to the point of incorporating maize and other cultivars; as well as the conditions for reversing the process. Specific expectations for the archaeological and paleoenvironmental record …

Activity Of The Porcine Gonadotropin-Releasing Hormone Receptor Gene Promoter Is Partially Conferred By A Distal Gonadotrope Specific Element (Gse) Within An Upstream Enhancing Region, Two Proximal Gses And A Retinoid X Receptor Binding Site, Rebecca Cederberg, Jacqueline Smith, Emily A. Mcdonald, Chanho Lee, Amy R. Perkins, Brett R. White

Department of Animal Science: Faculty Publications

Background: Regulation of gonadotropin-releasing hormone (GnRH) receptor (GnRHR) numbers on gonadotropes within the anterior pituitary gland represents a critical point for control of reproductive function. Binding of GnRH to its receptor regulates follicle stimulating hormone (FSH) and luteinizing hormone (LH) release and levels of this G-protein coupled receptor on the surface of gonadotropes determines their sensitivity to GnRH pulses. While transcriptional regulation of this gene has been studied in mice, rats, humans and sheep, little is known about its regulation in the pig, an important agricultural species and human research model.

Methods: We isolated 5118 bp of 5′ flanking …

High Moisture Extrusion Of Oatmeal, Brandon F. Coleman

Master's Theses

Oats are considered to be a highly nutritious breakfast food available to consumers. Heightened consumer interest in functional food products and advances in human nutrition have led to increased levels of interest in the development of new oat based products (Webster and Wood 2011). Developments in technology have led to manufacturing of instant oatmeal, making the product more convenient to consumers. Low moisture extrusion processing is one of the most widely used methods to produce ready to eat breakfast cereals; however, there has been little research carried out to determine if high moisture extrusion methods would be viable. This study …

Lost And Found: The Third Molars Of Callimico Goeldii And The Evolution Of The Callitrichine Postcanine Dentition, Jeremiah E. Scott

Publications

This study tests the hypothesis that the third molars of Callimico goeldii represent a reversal in evolutionary tooth loss within the Callitrichinae. Loss of third molars is part of a suite of unusual characters that has been used to unite marmosets and tamarins in a clade to the exclusion of Callimico. However, molecular phylogenetic studies provide consistent support for the hypothesis that marmosets are more closely related to Callimico than to tamarins, raising the possibility that some or all of the features shared by marmosets and tamarins are homoplastic. Here, I use the binary-state speciation and extinction (BiSSE) model …

Synergistic Effects Of Fire And Elephants On Arboreal Animals In An African Savanna, Robert M. Pringle, Duncan M. Kimuyu, Ryan L. Sensenig, Todd M. Palmer, Corinna Riginos, Kari E. Veblen, Truman P. Young

Wildland Resources Faculty Publications

1. Disturbance is a crucial determinant of animal abundance, distribution and community structure in many ecosystems, but the ways in which multiple disturbance types interact remain poorly understood. The effects of multiple-disturbance interactions can be additive, subadditive or super-additive (synergistic). Synergistic effects in particular can accelerate ecological change; thus, characterizing such synergies, the conditions under which they arise, and how long they persist has been identified as a major goal of ecology.
2. We factorially manipulated two principal sources of disturbance in African savannas, fire and elephants, and measured their independent and interactive effects on the numerically dominant vertebrate (the arboreal gekkonid …

Ucp1 Is An Essential Mediator Of The Effects Of Methionine Restriction On Energy Balance But Not Insulin Sensitivity, Desiree Wanders, David H. Burk, Cory C. Cortez, Nancy T. Van, Kirsten P. Stone, Mollye Baker, Tamra Mendoza, Randall L. Mynatt, Thomas W. Gettys

Faculty Publications

© FASEB. Dietary methionine restriction (MR) by 80%increases energy expenditure (EE), reduces adiposity, and improves insulin sensitivity. We propose that the MRinduced increase in EE limits fat deposition by increasing sympathetic nervous system-dependent remodeling of white adipose tissue and increasing uncoupling protein 1 (UCP1) expression in both white and brown adipose tissue. In independent assessments of the role of UCP1 as a mediator of MR's effects on EE and insulin sensitivity, EE did not differ between wild-type (WT) and Ucp1^-/- mice on the control diet, butMR increased EE by 31%and reduced adiposity by 25% in WT mice. In contrast, …

Disease And Dowry: Community Context, Gender, And Adult Health In India, Samuel Stroope

Faculty Publications

Despite growing research on health and residential contexts, relatively little is understood about gendered contexts that are differentially important for women's and men's physical health in low- and middle-income countries. This study advances the prior knowledge by examining whether the local frequency of a salient and gendered practice in India-dowry-is associated with gender differences in physical health (acute illness, illness length, and chronic illness). Analyses are conducted using multilevel logistic and negative binomial regression models and national data on men and women across India (N = 102,763). Results show that as dowry frequency increases in communities, not only do women …

Youth Peers Put The “Invent” Into Nutribee’S Online Intervention, Ingrid C. Kohlstadt, Elizabeth T. Anderson Steeves, Kerry Rice, Joel Gittelsohn, Liane M. Summerfield, Preety Gadhoke

Educational Technology Faculty Publications and Presentations

Background: Early adolescents perceive peers as credible and relatable. Peers therefore have a unique conduit to engage early adolescents in positive health behaviors through nutrition learning such as that recommended by the U.S. Institute of Medicine (IOM).

Purpose: We developed an online, peer leader component to an existing in-person preventive nutrition intervention called NutriBee. We reasoned that youth ages 13–18 could create intervention materials that could remain engaging, credible and relatable to younger peers ages 10–12 online. Peer leaders could potentially derive health benefits from their service-learning experience.

Methods: From 2013–2014 youth could apply online to relate a personal interest …

Sleep Hygiene Practices: A Cross Cultural Survey Of Sleeping And Dreaming In College Students, Ivan Noe Martinez Salazar

Masters Theses

There is consensus that a sizeable percentage of people in most developed countries do not obtain adequate amounts or quality of sleep. These disruptions in sleep, when chronic and severe, can lead to psychological, behavioral and health consequences. The focus on behavioral and contextual factors that impact sleep has been termed “sleep hygiene”. An on-line anonymous survey collected sociodemographic information, as well as self-reports on sleep, sleep hygiene practices and dreaming across two cultural groups (English & Spanish speaking responders). A total of 204 participants (majority of them college and graduate students) answered the survey. Both cultural groups, English and …

Understanding Nucleus Pulposus Cell Phenotype: A Prerequisite For Stem Cell Based Therapies To Treat Intervertebral Disc Degeneration., Hyowon Choi, Zariel I. Johnson, Makarand V. Risbud

Department of Orthopaedic Surgery Faculty Papers

Intervertebral disc (IVD) degeneration and associated low back pain (LBP) remains a major burden to our society without significant improvements in treatment strategies or patient's quality of life. While the recent cell-transplantation studies for treatment of degenerative disc disease have shown promising results, to better gauge the success and functional outcomes of these therapies, it is crucial to understand if transplanted cells give rise to healthy nucleus pulposus (NP) tissue. NP cell phenotype is unique and is defined by expression of a characteristic set of markers that reflect specialized physiology and function. This review summarizes phenotypic markers that mirror the …
