Selection And Genetic Drift In North American Maize, Collin Lamkey

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Characterizing the impact of selection and genetic drift in the formation of heterotic groups and patterns in maize can reveal important insights into the mechanism underlying adaptation, and the relative importance of each force in defining population structure. The objectives were to characterize the role selection for hybrid performance had in defining population structure in both a reciprocal full-sib selection (RFS) program and a large collection of historically important inbred lines.

The Illumina GoldenGate Assay was used to genotype the University of Nebraska-Lincoln Replicated Recurrent Selection (UNL-RpRS) program. Eight cycles of S1-progeny and RFS selection were conducted for an index …

Method Of Myelinating Isolated Motoneurons, James Hickman

UCF Patents

One of the most significant interactions between Schwann cells and neurons is myelin sheath formation. Myelination is a vertebrate adaptation that enables rapid conduction of action potentials without a commensurate increase in axon diameter. In vitro neuronal systems provide a unique modality to study both factors influencing myelination and diseases associated with myelination. Currently, no in vitro system for motoneuron myelination by Schwann cells has been demonstrated. This work details the myelination of motoneuron axons by Schwann cells, with complete node of Ranvier formation, in a defined in vitro culture system. This defined system utilizes a novel serum-free medium in …

Sorting Reality From What We Think We Know About Breast Cancer In Africa, Sulma I. Mohammed, Joe B. Harford

Department of Comparative Pathobiology Faculty Publications

Much attention has been paid to the features of breast cancer in Africa and the parallels between breast cancer in indigenous Africans and in African American women, including a shift toward earlier onset; a tendency toward poorer outcomes; and an increased likelihood for the tumors to be negative for the estrogen receptor (ER), the progesterone receptor (PR), and/or the human epidermal growth factor receptor-2 (HER2) [1,2]. One of the more aggressive forms of breast cancer is termed ‘‘triple negative,’’ i.e., ER2, PR2, HER22 [3]. Patients with triple negative breast cancer tend to be younger than patients with other forms of …

The Genetic Interacting Landscape Of 63 Candidate Genes In Major Depressive Disorder: An Explorative Study, Magnus Lekman, Ola Hössjer, Peter Andrews, Henrik Källberg, Daniel Uvehag, Dennis Charney, Husseini Manji, John A. Rush, Frances J. Mcmahon, Jason H Moore, Ingrid Kockum

Dartmouth Scholarship

Background:

Genetic contributions to major depressive disorder (MDD) are thought to result from multiple genes interacting with each other. Different procedures have been proposed to detect such interactions. Which approach is best for explaining the risk of developing disease is unclear.

This study sought to elucidate the genetic interaction landscape in candidate genes for MDD by conducting a SNP-SNP interaction analysis using an exhaustive search through 3,704 SNP-markers in 1,732 cases and 1,783 controls provided from the GAIN MDD study. We used three different methods to detect interactions, two logistic regressions models (multiplicative and additive) and one data mining and …

The Contributions Of Donald Lee Johnson To Understanding The Quaternary Geologic And Biogeographic History Of The California Channel Islands, Daniel R. Muhs

Monographs of the Western North American Naturalist

Over a span of 50 years, native Californian Donald Lee Johnson made a number of memorable contributions to our understanding of the California Channel Islands. Among these are (1) recognizing that carbonate dunes, often cemented into eolianite and derived from offshore shelf sediments during lowered sea level, are markers of glacial periods on the Channel Islands; (2) identifying beach rock on the Channel Islands as the northernmost occurrence of this feature on the Pacific Coast of North America; (3) recognizing of the role of human activities in historic landscape modification; (4) identifying both the biogenic and pedogenic origins of caliche …

The Differentiated Effects Of Lyrical And Non-Lyrical Music On Reading Comprehension, Cameron Miller

Theses and Dissertations

The present study seeks to observe the effect of background music on reading comprehension, specifically searching for possible differences between effects brought on by different genres (i.e. classical and rock) and the presence of lyrics. Research on task performance in the presence of background sound is mixed, in part due to the large number of possible applications. An overview of existing research on this topic is presented, including articles on the relationship between music and cognitive ability, distractors and processing resources, and pre-existing studies on music and reading comprehension. University students participated in a randomized experiment, taking the Reading Comprehension …

Evidence For Transfer Of Membranes From Mesenchymal Stem Cells To Hl-1 Cardiac Cells, Robert Boomsma, David Geenen

Open Access Publishing Support Funded Articles

This study examined the interaction of mouse bone marrow mesenchymal stem cells (MSC) with cardiac HL-1 cells during coculture by fluorescent dye labeling and then flow cytometry. MSC were layered onto confluent HL-1 cell cultures in a 1 : 4 ratio. MSC gained gap junction permeant calcein from HL-1 cells after 4 hours which was partially reduced by oleamide. After 20 hours, 99% MSC gained calcein, unaffected by oleamide. Double-labeling HL-1 cells with calcein and the membrane dye DiO resulted in transfer of both calcein and DiO to MSC. When HL-1 cells were labeled with calcein and MSC with DiO, …

Relaxed Substrate Specificity Leads To Extensive Trna Mischarging By Streptococcus Pneumoniae Class I And Class Ii Aminoacyl-Trna Synthetases, Jennifer Shepherd, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Aminoacyl-tRNA synthetases provide the first step in protein synthesis quality control by discriminating cognate from noncognate amino acid and tRNA substrates. While substrate specificity is enhanced in many instances by cis- and trans-editing pathways, it has been revealed that in organisms such as Streptococcus pneumoniae some aminoacyl-tRNA synthetases display significant tRNA mischarging activity. To investigate the extent of tRNA mischarging in this pathogen, the aminoacylation profiles of class I isoleucyl-tRNA synthetase (IleRS) and class II lysyl-tRNA synthetase (LysRS) were determined. Pneumococcal IleRS mischarged tRNA^Ile with both Val, as demonstrated in other bacteria, and Leu in a tRNA sequence-dependent …

Ergovaline Stability In Tall Fescue Based On Sample Handling And Storage Methods, Krista La Moen Lea, Lori Smith, Cynthia Gaskill, Robert Coleman, S. Ray Smith

Plant and Soil Sciences Faculty Publications

Ergovaline is an ergot alkaloid produced by the endophyte Neotyphodium coenophialum (Morgan-Jones and Gams) found in tall fescue [Schedonorus arundinacea (Schreb.) Dumort.] and blamed for a multitude of livestock disorders. Ergovaline is known to be unstable and affected by many variables. The objective of this study was to determine the effect of sample handling and storage on the stability of ergovaline in tall fescue samples. Fresh tall fescue was collected from a horse farm in central Kentucky at three harvest dates and transported on ice to the University of Kentucky Veterinary Diagnostic Laboratory. Plant material was frozen in liquid …

Everything Is Related, Neal Deroo

Protozoacidal Trojan-Horse: Use Of A Ligand-Lytic Peptide For Selective Destruction Of Symbiotic Protozoa Within Termite Guts, Amit Sethi, Jennifer Delatte, Lane Foil, Claudia Husseneder

Faculty Publications

© 2014 Sethi et al. For novel biotechnology-based termite control, we developed a cellulose bait containing freeze-dried genetically engineered yeast which expresses a protozoacidal lytic peptide attached to a protozoa-recognizing ligand. The yeast acts as a 'Trojan-Horse' that kills the cellulose-digesting protozoa in the termite gut, which leads to the death of termites, presumably due to inefficient cellulose digestion. The ligand targets the lytic peptide specifically to protozoa, thereby increasing its protozoacidal efficiency while protecting non-target organisms. After ingestion of the bait, the yeast propagates in the termite's gut and is spread throughout the termite colony via social interactions. This …

Gene Expression Analysis Of Bovine Peripheral Blood Mononuclear Cells In Response To Adenovirus-Vectored Foot-And-Mouth Disease Vaccine, Frank Zappulla

Master's Theses

Foot-and-mouth disease virus (FMDV) gives rise to a highly contagious and economically important disease of cloven-hooved animals. Vaccination reduces the economic impact by inducing serotype-specific protection. Recently, a replication-defective adenovirus-vectored foot-and-mouth disease (FMD) subunit vaccine was developed and licensed. Serum virus neutralization (SVN) titer ≥1.5 to FMDV is the best predictor of vaccine-induced protection. However, protection does not always correlate with the presence of neutralizing antibodies. For example, some animals with high SVN titer develop signs of disease, and conversely, some animals with negligible SVN titer are protected. Categorizing cattle on the parameters of seroconversion and protection status yields four …

Dartmouth Scholarship

Background: A growing body of evidence suggests that exposure to toxic metals occurs through diet but few studies have comprehensively examined dietary sources of exposure in US populations.

Purpose: Our goal was to perform a novel dietary-wide association study (DWAS) to identify specific dietary sources of lead, cadmium, mercury, and arsenic exposure in US children and adults.

Methods: We combined data from the National Health and Nutrition Examination Survey with data from the US Department of Agriculture’s Food Intakes Converted to Retail Commodities Database to examine associations between 49 different foods and environmental metal exposure. Using blood and urinary biomarkers …

Induced Phytoextraction Of Lead From Contaminated Urban Soil Through Manipulation Of Rhizosphere And Plant Biogeochemical Functions In Switchgrass (Panicum Virgatum), Deayne M. Johnson

Master of Science in Integrative Biology Theses

Contamination of soils with lead (Pb) continues to pose a risk to the health of humans especially in residential urban areas. Remediation of these soils is necessary to reduce the amount of Pb and alleviate risk to human health. Phytoextraction of Pb through chemically induced accumulation of Pb in the harvestable foliage and removal of contaminated plant material has great potential in offering a solution to this environmental problem. The effects of the combined application of a soil fungicide (benomyl), synthetic chelates (ethylenediamineteteraacetic acid, EDTA), and foliar-Fe supplement on lead (Pb) phytoextraction from contaminated soil by switchgrass (Panicum virgatum) was …
