Differences In Ultrasonic Vocalizations Between Wild And Laboratory California Mice (Peromyscus Californicus), M. C. Kalcounis-Rueppell, R. Petric, J. R. Briggs, C. Carney, M. M. Marshall, J. T. Willse, David O. Ribble, J. P. Crossland

Biology Faculty Research

Background: Ultrasonic vocalizations (USVs) emitted by muroid rodents, including laboratory mice and rats, are used as phenotypic markers in behavioral assays and biomedical research. Interpretation of these USVs depends on understanding the significance of USV production by rodents in the wild. However, there has never been a study of muroid rodent ultrasound function in the wild and comparisons of USVs produced by wild and laboratory rodents are lacking to date. Here, we report the first comparison of wild and captive rodent USVs recorded from the same species, Peromyscus californicus.

Methodology and Principal Findings: We used standard ultrasound recording techniques to ...

High-Throughput Snp Discovery Through Deep Resequencing Of A Reduced Representation Library To Anchor And Orient Scaffolds In The Soybean Whole Genome Sequence, David L. Hyten, Steven B Cannon, Qijian Song, Nathan Weeks, Edward W Fickus, Randy C Shoemaker, James E. Specht, Andrew D Farmer, Gregory D May, Perry B Cregan 2010 USDA-ARS

High-Throughput Snp Discovery Through Deep Resequencing Of A Reduced Representation Library To Anchor And Orient Scaffolds In The Soybean Whole Genome Sequence, David L. Hyten, Steven B Cannon, Qijian Song, Nathan Weeks, Edward W Fickus, Randy C Shoemaker, James E. Specht, Andrew D Farmer, Gregory D May, Perry B Cregan

Agronomy & Horticulture -- Faculty Publications

Background: The Soybean Consensus Map 4.0 facilitated the anchoring of 95.6% of the soybean whole genome sequence developed by the Joint Genome Institute, Department of Energy, but its marker density was only sufficient to properly orient 66% of the sequence scaffolds. The discovery and genetic mapping of more single nucleotide polymorphism (SNP) markers were needed to anchor and orient the remaining genome sequence. To that end, next generation sequencing and high-throughput genotyping were combined to obtain a much higher resolution genetic map that could be used to anchor and orient most of the remaining sequence and to help ...


Distribution And Ecotypic Variation Of The Invasive Annual Barb Goatgrass (Aegiolops Triuncialis) On Serpentine Soil, Kelly G. Lyons, A M. Shapiro, M. W. Schwartz 2010 Trinity University

Distribution And Ecotypic Variation Of The Invasive Annual Barb Goatgrass (Aegiolops Triuncialis) On Serpentine Soil, Kelly G. Lyons, A M. Shapiro, M. W. Schwartz

Biology Faculty Research

Successful colonization of newly introduced species is driven by a multitude of factors and is highly dependent on the species. It has long been hypothesized that preadaptation and postestablishment natural selection of introduced species can facilitate their invasion; however, to date, limited research has been dedicated to these theories. In addition, although the correlation between establishment of invasive species and disturbance has been noted and widely studied, the susceptibility of undisturbed habitats to invasion remains unclear. In California, serpentine habitats are severe edaphic environments that have been relatively free of anthropogenic disturbance and nonindigenous species invasions. In this study, we ...


Complexity And Human Gait, Leslie M. Decker, Fabien Cignetti, Nicholas Stergiou 2010 University of Nebraska at Omaha

Complexity And Human Gait, Leslie M. Decker, Fabien Cignetti, Nicholas Stergiou

Journal Articles

Recently, the complexity of the human gait has become a topic of major interest within the field of human movement sciences. Indeed, while the complex fluctuations of the gait patterns were, for a long time, considered as resulting from random processes, the development of new techniques of analysis, so-called nonlinear techniques, has open new vistas for the understanding of such fluctuations. In particular, by connecting the notion of complexity to the one of chaos, new insights about gait adaptability, unhealthy states in gait and neural control of locomotion were provided. Through methods of evaluation of the complexity, experimental results obtained ...


Variability Of Lower Extremity Joint Kinematics During Backward Walking In A Virtual Environment, Dimitrios Kastavelis, Mukul Mukherjee, Leslie M. Decker, Nicholas Stergiou 2010 University of Nebraska at Omaha

Variability Of Lower Extremity Joint Kinematics During Backward Walking In A Virtual Environment, Dimitrios Kastavelis, Mukul Mukherjee, Leslie M. Decker, Nicholas Stergiou

Journal Articles

Backward walking (BW) shows significant differences with forward walking (FW) and these differences are potentially useful in rehabilitation. However the lack of visual cues makes BW risky. The purpose of this study was to investigate the effect of visual cues provided by a virtual environment on FW and BW on gait variability. Each subject underwent four conditions of treadmill walking at self-selected pace. The subjects walked backwards in three conditions and forwards in the fourth condition. A virtual corridor was displayed to the subjects in the FW condition (forward optic flow) and two of the backward conditions (forward and backward ...


Cell-Cell Junction Signaling Regulating Dna Double-Strand Break Repair In Breast Cells, SINDUJA ETHIRAJ 2010 Virginia Commonwealth University

Cell-Cell Junction Signaling Regulating Dna Double-Strand Break Repair In Breast Cells, Sinduja Ethiraj

Theses and Dissertations

Genomic instability and acquisition of invasiveness through the basement membrane extracellular matrix (ECM) are two major processes for epithelial cell malignancy in breast cancer. DNA double-strand break repair (DSBR) is one of the processes that get misregulated during breast cancer progression. In addition, radiation induced breaks such as those induced during radiation therapy to treat breast cancer patients are repaired by DSBR, rendering this pathway relevant for therapy as well. DSBR can occur either by homologous recombination (HR) or non-homologous end-joining (NHEJ). HR is accepted as the more error-free pathway. HR is regulated by the cell cycle status such that ...

An Intelligent Data-Centric Approach Toward Identification Of Conserved Motifs In Protein Sequences, Kathryn Dempsey Cooper, Benjamin Currall, Richard Hallworth, Hesham Ali 2010 University of Nebraska at Omaha

An Intelligent Data-Centric Approach Toward Identification Of Conserved Motifs In Protein Sequences, Kathryn Dempsey Cooper, Benjamin Currall, Richard Hallworth, Hesham Ali

Interdisciplinary Informatics Faculty Proceedings & Presentations

The continued integration of the computational and biological sciences has revolutionized genomic and proteomic studies. However, efficient collaboration between these fields requires the creation of shared standards. A common problem arises when biological input does not properly fit the expectations of the algorithm, which can result in misinterpretation of the output. This potential confounding of input/output is a drawback especially when regarding motif finding software. Here we propose a method for improving output by selecting input based upon evolutionary distance, domain architecture, and known function. This method improved detection of both known and unknown motifs in two separate case ...


Biochemical Profiling Of Histone Binding Selectivity Of The Yeast Bromodomain Family, Qiang Zhang, Suvobrata Chakravarty, Dario Ghersi, Lei Zeng, Alexander N. Plotnikov, Roberto Sanchez, Ming-Ming Zhou 2010 University of Nebraska at Omaha

Biochemical Profiling Of Histone Binding Selectivity Of The Yeast Bromodomain Family, Qiang Zhang, Suvobrata Chakravarty, Dario Ghersi, Lei Zeng, Alexander N. Plotnikov, Roberto Sanchez, Ming-Ming Zhou

Interdisciplinary Informatics Faculty Publications

Background: It has been shown that molecular interactions between site-specific chemical modifications such as acetylation and methylation on DNA-packing histones and conserved structural modules present in transcriptional proteins are closely associated with chromatin structural changes and gene activation. Unlike methyl-lysine that can interact with different protein modules including chromodomains, Tudor and MBT domains, as well as PHD fingers, acetyl-lysine (Kac) is known thus far to be recognized only by bromodomains. While histone lysine acetylation plays a crucial role in regulation of chromatin-mediated gene transcription, a high degree of sequence variation of the acetyl-lysine binding site in the bromodomains has limited ...


Dependency On De Novo Protein Synthesis And Proteomic Changes During Metamorphosis Of The Marine Bryozoan Bugula Neritina, Yue Him Wong, Shawn M. Arellano, Huoming Zhang, Timothy Ravasi, Pei-Yuan Qian 2010 Western Washington University

Dependency On De Novo Protein Synthesis And Proteomic Changes During Metamorphosis Of The Marine Bryozoan Bugula Neritina, Yue Him Wong, Shawn M. Arellano, Huoming Zhang, Timothy Ravasi, Pei-Yuan Qian

Shannon Point Marine Center Faculty Publications

Background: Metamorphosis in the bryozoan Bugula neritina (Linne) includes an initial phase of rapid morphological rearrangement followed by a gradual phase of morphogenesis. We hypothesized that the first phase may be independent of de novo synthesis of proteins and, instead, involves post-translational modifications of existing proteins, providing a simple mechanism to quickly initiate metamorphosis. To test our hypothesis, we challenged B. neritina larvae with transcription and translation inhibitors. Furthermore, we employed 2D gel electrophoresis to characterize changes in the phosphoproteome and proteome during early metamorphosis. Differentially expressed proteins were identified by liquid chromatography tandem mass spectrometry and their gene expression ...

Litter-Carbon Dynamics: The Importance Of Decomposition, Accretion, And Sequestration In Understanding Ecosystem Carbon Cycling, Amy Kochsiek 2010 University of Nebraska at Lincoln

Litter-Carbon Dynamics: The Importance Of Decomposition, Accretion, And Sequestration In Understanding Ecosystem Carbon Cycling, Amy Kochsiek

Dissertations and Theses in Biological Sciences

The atmospheric CO2 concentration has been increasing since the industrial revolution. A proposed mitigation strategy is sequestering carbon (C) in terrestrial ecosystems, either in plant biomass or soil organic matter. The litter-C pool is the second largest C pool in agroecosystems post-harvest, and the amount of litter-C loss has been correlated with ecosystem respiration. Yet, the potential importance of the litter pool as one of the major C pools in a system is relatively unknown. We do, however, know that the size of the litter pool can be affected by increases or decreases in both litter-C production and decomposition ...


Dna Replication And Genome Maintenance Of Human Papillomavirus Type 16 In Mammalian Cells, Daraporn Pittayakhajonwut 2010 University of Nebraska - Lincoln

Dna Replication And Genome Maintenance Of Human Papillomavirus Type 16 In Mammalian Cells, Daraporn Pittayakhajonwut

Dissertations and Theses in Biological Sciences

Human papillomavirus (HPV) is a major causative agent of cervical cencer and a number of human cancers. The high‐risk types can be detected in more than 90% of cervical cancer, of which HPV16 is the most common found. The virus establishes a latent infection in basal epithelial cells in which the viral genomes can be stably maintained as extrachromosomal DNA for decades before the development of cancer. Several attempts have been made in bovine papillomavirus (BPV) to understand how the virus can maintain its genome at constant copy numbers in dividing cells. The viral protein E2 has been proposed ...


Selection For Increased Starvation Resistance Using Drosophila Melanogaster: Investigating Physiological And Life History Trait Responses To Starvation And Dietary Supplementation In The Context Of An Obese Phenotype, Tiffany Elisse Schwasinger-Schmidt 2010 University of Nebraska at Lincoln

Selection For Increased Starvation Resistance Using Drosophila Melanogaster: Investigating Physiological And Life History Trait Responses To Starvation And Dietary Supplementation In The Context Of An Obese Phenotype, Tiffany Elisse Schwasinger-Schmidt

Dissertations and Theses in Biological Sciences

Artificial selection for starvation resistance provided insight into the relationships between evolved physiological and life history trait responses following exposure to biologically induced stress. Investigations of alterations to body composition, metabolic rate, movement, and life history traits including development time, female egg production, and longevity in response to brief periods of starvation were conducted on genetically based starvation-resistant and control lines of Drosophila melanogaster. Analysis of the starvation-resistant lines indicated increased energy storage with increased triglyceride deposition and conversion of carbohydrates to lipid, as identified by respiratory quotient values. Correlations between reductions in metabolic rates and movement in the starvation-resistant ...


Incorporation Of Europium (Iii) Coordination Compounds Into Silica Microspheres, Johnathan Nathanael Brantly 2010 Western Kentucky University

Incorporation Of Europium (Iii) Coordination Compounds Into Silica Microspheres, Johnathan Nathanael Brantly

Honors College Capstone Experience/Thesis Projects

The unique optical properties of silica microspheres and lanthanoid elements present the opportunity to adapt silica microspheres containing rare earth elements for novel optical applications. The research demonstrates the first example of incorporating insoluble lanthanoid coordination compounds into silica microspheres. The work explored the controlled synthesis of silica microspheres and the reaction conditions under which lanthanoid complexes can be incorporated into the microspheres. The environment of the coordinated lanthanoid ions before and after incorporation into silica microspheres was probed using spectroflurophotometry. The surface morphology of silica microspheres was characterized using atomic force microscopy (AFM) and scanning electron microscopy (SEM). The ...


Implementation Of Supervised Agricultural Experience Programs: The Agriculture Teachers' Perspective, Michael S. Retallick 2010 Iowa State University

Implementation Of Supervised Agricultural Experience Programs: The Agriculture Teachers' Perspective, Michael S. Retallick

Agricultural Education and Studies Publications

The purpose of this qualitative exploratory study was to examine how agriculture teachers implement supervised agricultural experience (SAE). A combination of focus groups and individual telephone interviews were conducted. Iowa agriculture teachers offered SAE because it is (a) a means of developing life skills, (b) a component of the FFA award system, and (c) theoretically, one–third of the agricultural education model. Although agriculture teachers were able to talk conceptually and theoretically about the benefits and value of SAE, they did not necessarily practice SAE in that manner. The method in which teachers implemented SAE programs varied considerably as did ...
