Influence Of Translocations On Eastern Wild Turkey Population Genetics In Texas, Christopher E. Comer, Warren C. Conway, Gary Calkins, Sabrina Seidel, Randy Deyoung, Jason Hardin

Faculty Publications

Between 1979 and 2006, over 7,000 eastern wild turkeys (Meleagris gallopavo silvestris) from 16 states were translocated to east Texas in an attempt to restore a stable, huntable population. Although current populations are stable in some areas and a spring male-only hunting season was opened in 1995, turkey density in the region remains low and large areas of apparently suitable habitat are not occupied. The longterm effects of the extensive translocations and current levels of connectivity among various populations are unknown. We used microsatellite DNA analysis to assess the influence of translocations on current genetic structure and gene flow in …

Using Gis-Based, Regional Extent Habitat Suitability Modeling To Identify Conservation Priority Areas: A Case Study Of The Louisiana Black Bear In East Texas, Christopher E. Comer, I-Kuai Hung, Gary Calkins, Dan J. Kaminski, Nathan Garner

Faculty Publications

State and federal recovery plans mandate that priority areas for future population expansion be identified within the historical range of the Louisiana black bear (Ursus americanus luteolus). Despite the presence of potentially suitable habitat in east Texas and expanding populations in adjacent states, quantitative estimates of regional habitat suitability do not exist. We developed a regional extent habitat suitability index (HSI) model in a geographic information system (GIS) to evaluate year-round habitat requirements for black bears in the 43,530-km2 south black bear recovery zone in southeastern Texas. We measured hard and soft mast production, understory vegetation density, and tree den …

Seasonal Variation In Offspring Sex Ratio In The Snowy Plover, Sarah T. Saalfeld, Warren C. Conway, David A. Haukos, William P. Johnson

Faculty Publications

The Snowy Plover (Charadrius nivosus) is unique in being a determinate layer of an odd modal clutch size and in having a variable mating system in which female brood desertion occurs regularly. These traits make determining Snowy Plover offspring sex ratios important not only for long-term population stability, as the species is of conservation concern, but also for application to sex allocation theory. In this study, we determined Snowy Plover offspring sex ratios, examined differential costs of producing male and female offspring, and evaluated sex ratio variation in relation to maternal condition, habitat condition, and time during the …

Assessing Residual Reasoning Ability In Overtly Non-Communicative Patients Using Fmri, Adam Hampshire, Beth L. Parkin, Rhodri Cusack, Davinia Fernandez Espejo, Judith Allanson, Evelyn Kamau, John D. Pickard, Adrian M. Owen

Anatomy and Cell Biology Publications

It is now well established that some patients who are diagnosed as being in a vegetative state or a minimally conscious state show reliable signs of volition that may only be detected by measuring neural responses. A pertinent question is whether these patients are also capable of logical thought. Here, we validate an fMRI paradigm that can detect the neural fingerprint of reasoning processes and moreover, can confirm whether a participant derives logical answers. We demonstrate the efficacy of this approach in a physically non-communicative patient who had been shown to engage in mental imagery in response to simple auditory …

Assessing The Feasibility Of Time-Resolved Fnirs To Detect Brain Activity During Motor Imagery, Androu Abdalmalak, Daniel Milej, Mamdou Diop, Lorina Naci, Adrian M. Owen, Keith St. Lawrence

Anatomy and Cell Biology Publications

Functional near-infrared spectroscopy (fNIRS) is a non-invasive optical technique for detecting brain activity, which has been previously used during motor and motor executive tasks. There is an increasing interest in using fNIRS as a brain computer interface (BCI) for patients who lack the physical, but not the mental, ability to respond to commands. The goal of this study is to assess the feasibility of time-resolved fNIRS to detect brain activity during motor imagery. Stability tests were conducted to ensure the temporal stability of the signal, and motor imagery data were acquired on healthy subjects. The NIRS probes were placed on …

Assessing Tumor Physiology By Dynamic Contrast-Enhanced Near-Infrared Spectroscopy, Kyle Verdecchia, Jonathan Elliott, Mamadou Diop, Lisa Hoffman, Ting-Yim Lee, Keith St. Lawrence

Anatomy and Cell Biology Publications

The purpose of this study was to develop a dynamic contrast-enhanced (DCE) near-infrared spectroscopy (NIRS) technique to characterize tumor physiology. Dynamic data were acquired using two contrast agents of different molecular weights, indocyanine green (ICG) and IRDye 800CW carboxylate (IRDcxb). The DCE curves were analyzed using a kinetic model capable of extracting estimates of tumor blood flow (F), capillary transit time (t(c)) and the amount of dye that leaked into the extravascular space (EVS) - characterized by the extraction fraction (E). Data were acquired from five nude rats with tumor xenografts (>10mm) implanted in the neck. Four DCE-NIR datasets …

Development Of A 3d Ultrasound System To Investigate Post-Hemorrhagic Hydrocephalus In Pre-Term Neonates, J. Kishimoto, D. Lee, K. St. Lawrence, W. Romano, A. Fenster, S. De Ribaupierre

Anatomy and Cell Biology Publications

Clinical intracranial ultrasound (US) is performed as a standard of care on neonates at risk of intraventricular hemorrhaging (IVH) and is also used after a diagnosis to monitor for potential ventricular dilation. However, it is difficult to estimate the volume of ventricles with 2D US due to their irregular shape. We developed a 3D US system to be used as an adjunct to a clinical system to investigate volumetric changes in the ventricles of neonates with IVH. Our system has been found have an error of within 1% of actual distance measurements in all three directions and volume measurements of …

'Deviant' Burials In Archaeology, Jesslyn E. Hodgson

Anthropology Publications

The term ‘deviant’ is used to describe burials that deviate from the normative burial rites of a given society, at a given point in time. The problem with applying such a term to the archaeological record rests predominantly in the fact that the term ‘deviant’ has a negative connotation. This negative connotation insinuates that the individual in the burial context may have been viewed by their society in a negative light, however, through analysis of case studies it is shown that many ‘deviant’ burials are not in fact burials of people viewed as deviant, but ‘different’ burials given to people …

Metabolism Of Brain Cortex And Cardiac Muscle Mitochondria In Hibernating 13-Lined Ground Squirrels Ictidomys Tridecemlineatus., Kirsten Gallagher, James F Staples

Biology Publications

During bouts of torpor, mitochondrial metabolism is known to be suppressed in the liver and skeletal muscle of hibernating mammals. This suppression is rapidly reversed during interbout euthermic (IBE) phases, when whole-animal metabolic rate and body temperature (T(b)) return spontaneously to euthermic levels. Such mitochondrial suppression may contribute significantly to energy savings, but the capacity of other tissues to suppress mitochondrial metabolism remains unclear. In this study we compared the metabolism of mitochondria from brain cortex and left ventricular cardiac muscle between animals sampled while torpid (stable T(b) near 5°C) and in IBE (stable T(b) near 37°C). Instead of isolating …

Theorizing Intercultural Adaptation From The Perspective Of Boundary Game, Guo-Ming Chen

Communication Studies Faculty Publications

The impact of globalization on human society strongly demands a constructive process of intercultural adaptation and a more systematic study of the concept. In order to tackle the problem of conceptual ambiguity in the existing literature, this analytical paper attempts to lay down the conceptual foundation by theorizing intercultural adaptation as a boundary game after a brief review of the previous literature. Intercultural adaptation as a boundary game is further supported by the argument that the boundary game of intercultural adaptation must be treated as totality. The author then advocates “boundary wisdom” as the key to the success of achieving …

Development Of Matrix Assisted Ionization Methods For Characterization Of Soluble And Insoluble Proteins From Native Environments By Mass Spectrometry, Ellen Dela Victoria Inutan

Wayne State University Dissertations

Matrix-assisted laser/desorption ionization (MALDI) and electrospray ionization (ESI) have made a huge impact in the analysis of biological materials. ESI has gained its popularity involving liquid based analysis, efficient fragmentation, chromatographic and electrophoretic separations but has a limitation for solubility restricted materials and surface analysis. MALDI is applicable to large biomolecule analysis and for surface methods useful for tissue imaging but is limited for structural characterization due to poor fragmentation and is ill suited for liquid based separation methods. The research presented here relates to new ionization methods that encompass the benefits of ESI and MALDI. These novel ionization methods …

Transmission Rate In Partial Differential Equation In Epidemic Models, Alaa Elkadry

Theses, Dissertations and Capstones

The rate at which susceptible individuals become infected is called the transmission rate. It is important to know this rate in order to study the spread and the effect of an infectious disease in a population. This study aims at providing an understanding of estimating the transmission rate from mathematical models representing the population dynamics of an infectious diseases using two different methods. Throughout, it is assumed that the number of infected individuals is known. In the first chapter, it includes historical background for infectious diseases and epidemic models and some terminology needed to understand the problems. Specifically, the partial …

Methylpca: A Toolkit To Control For Confounders In Methylome-Wide Association Studies, Wenan Chen, Guimin Gao, Srilaxmi Nerella, Christina M. Hultman, Patrik K.E. Magnusson, Patrick F. Sullivan, Karolina A. Aberg, Edwin J.C.G. Van Den Oord

Biostatistics Publications

Background

In methylome-wide association studies (MWAS) there are many possible differences between cases and controls (e.g. related to life style, diet, and medication use) that may affect the methylome and produce false positive findings. An effective approach to control for these confounders is to first capture the major sources of variation in the methylation data and then regress out these components in the association analyses. This approach is, however, computationally very challenging due to the extremely large number of methylation sites in the human genome.

Result

We introduce MethylPCA that is specifically designed to control for potential confounders in studies …

An Inferential Framework For Biological Network Hypothesis Tests, Phillip D. Yates, Nitai D. Mukhopadhyay

Biostatistics Publications

Background

Networks are ubiquitous in modern cell biology and physiology. A large literature exists for inferring/proposing biological pathways/networks using statistical or machine learning algorithms. Despite these advances a formal testing procedure for analyzing network-level observations is in need of further development. Comparing the behaviour of a pharmacologically altered pathway to its canonical form is an example of a salient one-sample comparison. Locating which pathways differentiate disease from no-disease phenotype may be recast as a two-sample network inference problem.

Results

We outline an inferential method for performing one- and two-sample hypothesis tests where the sampling unit is a network and the …

Individual, Environmental, And Meteorological Predictors Of Daily Personal Ultraviolet Radiation Exposure Measurements In A United States Cohort Study, Elizabeth K. Cahoon, David C. Wheeler, Michael G. Kimlin, Richard K. Kwok, Bruce H. Alexander, Mark P. Little, Martha S. Linet, Daryl M. Freedman

Biostatistics Publications

Background

Individual exposure to ultraviolet radiation (UVR) is challenging to measure, particularly for diseases with substantial latency periods between first exposure and diagnosis of outcome, such as cancer. To guide the choice of surrogates for long-term UVR exposure in epidemiologic studies, we assessed how well stable sun-related individual characteristics and environmental/meteorological factors predicted daily personal UVR exposure measurements.

Methods

We evaluated 123 United States Radiologic Technologists subjects who wore personal UVR dosimeters for 8 hours daily for up to 7 days (N = 837 days). Potential predictors of personal UVR derived from a self-administered questionnaire, and public databases that provided …

A Cohort Study Evaluation Of Maternal Pcb Exposure Related To Time To Pregnancy In Daughters, Chris Gennings, Caroline Carrico, Pam Factor-Litvak, Nickilou Krigbaum, Piera M. Cirillo, Barbara Cohn

Biostatistics Publications

Background Polychlorinated biphenyls (PCBs) remain ubiquitous environmental contaminants. Developmental exposures are suspected to impact reproduction. Analysis of mixtures of PCBs may be problematic as components have a complex correlation structure, and along with limited sample sizes, standard regression strategies are problematic. We compared the results of a novel, empirical method to those based on categorization of PCB compounds by (1) hypothesized biological activity previously proposed and widely applied, and (2) degree of ortho- substitution (mono, di, tri), in a study of the relation of maternal serum PCBs and daughter’s time to pregnancy.

Methods We measured PCBs in maternal serum samples …

Diet And Nutrition In Cancer Survivorship And Palliative Care., Anthony J Bazzan, Andrew B Newberg, William C Cho, Daniel A Monti

Marcus Institute of Integrative Health Faculty Papers

The primary goal of palliative cancer care is typically to relieve suffering and improve quality of life. Most approaches to diet in this setting have focused only on eating as many calories as possible to avoid cachexia. However, as the concept of palliative care has evolved to include all aspects of cancer survivorship and not just end of life care, there is an increasing need to thoughtfully consider diet and nutrition approaches that can impact not only quality of life but overall health outcomes and perhaps even positively affect cancer recurrence and progression. In this regard, there has been a …

Plants As Bio-Indicators Of Subsurface Conditions: Impact Of Groundwater Level On Btex Concentrations In Trees, Jordan Wilson, Rachel Bartz, Matt Limmer, Joel Gerard Burken

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Numerous Studies Have Demonstrated Trees' Ability to Extract and Translocate Moderately Hydrophobic Contaminants, and Sampling Trees for Compounds Such as BTEX Can Help Delineate Plumes in the Field. However, When BTEX is Detected in the Groundwater, Detection in Nearby Trees is Not as Reliable an Indicator of Subsurface Contamination as Other Compounds Such as Chlorinated Solvents. Aerobic Rhizospheric and Bulk Soil Degradation is a Potential Explanation for the Observed Variability of BTEX in Trees as Compared to Groundwater Concentrations. the Goal of This Study Was to Determine the Effect of Groundwater Level on BTEX Concentrations in Tree Tissue. the Central …

Legitimacy, Adaptation And Resilience In Ecosystem Management, Barbara Cosens

Articles

Ecologists have made great strides in developing criteria for describing the resilience of an ecological system. In addition, expansion of that effort to social-ecological systems has begun the process of identifying changes to the social system necessary to foster resilience in an ecological system such as the use of adaptive management and integrated ecosystem management. However, these changes to governance needed to foster ecosystem resilience will not be adopted by democratic societies without careful attention to their effect on the social system itself. Delegation of increased flexibility for adaptive management to resource management agencies must include careful attention to assuring …
