Frontal Brain Injury: Effects On Flexibility, Impulse Control, And Attention, Christopher Matthew O'Hearn 2020 WVU

Frontal Brain Injury: Effects On Flexibility, Impulse Control, And Attention, Christopher Matthew O'Hearn

Graduate Theses, Dissertations, and Problem Reports

Traumatic Brain Injury (TBI) is defined as an impact to the head, penetration of the skull, or rapid deceleration of the skull, resulting in an alteration of brain function or neurological deficit. Cognitive deficits are common following TBI and often go unresolved due to a lack of effective treatments. These deficits often perseverate into the chronic post injury phase, so the development of rehabilitative strategies is imperative. Behavioral flexibility, impulse control, and attention are a few cognitive processes that are commonly affected by TBI. The current research compares these processes between rats with and without a severe frontal brain injury …


Evaluating The Occurrence Of Age-Related Peripheral Neuropathy In Het3 Mice And Development Of A Whole Tissue Imaging Technique For Analyzing Total Innervation In The Subcutaneous Adipose Depot, Jake Willows 2019 University of Maine

Evaluating The Occurrence Of Age-Related Peripheral Neuropathy In Het3 Mice And Development Of A Whole Tissue Imaging Technique For Analyzing Total Innervation In The Subcutaneous Adipose Depot, Jake Willows

Electronic Theses and Dissertations

Adipose tissue can be characterized as either being a white (energy storing) depot or a brown (energy expending) depot and both have been found to contain dense networks of neural innervation. This adipose nerve supply regulates numerous metabolic functions and likely plays an important role in the function of adipose blood vessels. Recently our lab has shown in the C57BL/6 mouse model that peripheral neuropathy, or the dying back and dysfunction of the nerves in the superficial tissues such as the skin, can extend into the subcutaneous adipose tissue in conditions commonly associated with the neuropathic phenotype (i.e. diabetes, obesity, …


Establishing An Ideal Inclusion Rate Of Fermented Soybean Meal And Sodium Butyrate On Growth Performance, Complete Blood Cell Count, And Nutrient Utilization In Nursery Pigs, Kristopher A. Bottoms 2019 University of Arkansas, Fayetteville

Establishing An Ideal Inclusion Rate Of Fermented Soybean Meal And Sodium Butyrate On Growth Performance, Complete Blood Cell Count, And Nutrient Utilization In Nursery Pigs, Kristopher A. Bottoms

Graduate Theses and Dissertations

To evaluate increasing levels of sodium butyrate (SB) in nursery diets on growth performance (Experiment 1 & 2), complete blood cell count (Experiment 2), and the optimal level of fermented soybean meal for maximum performance in weanling pigs (Experiment 3), weaned pigs were blocked with initial body weight (BW) and allotted to dietary treatments. Treatments were: 1) Control (C) moderately complex corn-soybean-meal based supplemented with 0.05% benzoic acid (BA), but devoid of SB; C diet supplemented with 0.05%, 0.10%, or 0.15% SB (Experiment 1). Treatments in experiment 2 consisted of 1) a moderately complex corn-soybean-meal based diet devoid of SB …


Estimation Of Genetic Components Related To Infectious Bovine Keratoconjunctivitis Susceptibility In Angus And Angus Derived Cattle Produced In The Southern United States, Eric Oxford 2019 University of Arkansas, Fayetteville

Estimation Of Genetic Components Related To Infectious Bovine Keratoconjunctivitis Susceptibility In Angus And Angus Derived Cattle Produced In The Southern United States, Eric Oxford

Graduate Theses and Dissertations

The economic impact of infectious bovine keratoconjunctivitis (IBK) has been documented in many parts of the world. Many researchers have observed that prevention of this disease is very difficult given current methodologies. This is primarily due to the multifactorial nature of this disease. The objective of this dissertation was to determine the impact of IBK on calf performance and estimate genetic parameters, heritability and estimated breeding values for IBK susceptibility. Data were analyzed using PROC GLIMMIX of SAS; while genetic parameters were estimated using a linear animal model for both single- and two-traits through MTDFREML. Additional evaluations calculated heritability using …


Environmental Risk Factors For Inflammatory Bowel Disease: Triclosan And Other Consumer Antimicrobials, Katherine Z. Sanidad 2019 University of Massachusetts Amherst

Environmental Risk Factors For Inflammatory Bowel Disease: Triclosan And Other Consumer Antimicrobials, Katherine Z. Sanidad

Doctoral Dissertations

Inflammatory bowel disease (IBD) has become a serious health problem since the incidence and prevalence of IBD has dramatically increased throughout the world. There is evidence that environmental factors are primarily responsible for the increase of IBD, therefore, it is important to identify novel environmental risk factors to reduce the risk of IBD and its associated diseases. Antimicrobials used in consumer products might serve as environmental risk factors for IBD and its associated diseases. Triclosan (TCS), triclocarban (TCC), benzalkonium chloride (BAC), benzethonium chloride (BET), and chloroxylenol (PCMX) are widely used antimicrobial ingredients in consumer products and are ubiquitous contaminants in …


Patterns Of Morphological Plasticity In Metriaclima Zebra And Danio Rerio Suggest Differently Canalized Phenotypes Due To Form-Function Relationships, Dylan Jockel 2019 University of Massachusetts Amherst

Patterns Of Morphological Plasticity In Metriaclima Zebra And Danio Rerio Suggest Differently Canalized Phenotypes Due To Form-Function Relationships, Dylan Jockel

Masters Theses

In order to ascertain the degree of compatibility in developmental restructuring and behavioral plasticity between two fish species frequently made subject of laboratory research (Metriaclima zebra & Danio rerio), alternative trophic niche exposure experiments utilizing novel three-prong feeding treatments were conducted to obtain morphometric data, which demonstrated both species do bear some degree of plasticity. The results are somewhat complicated by differences in locality of detectable restructuring, which may be due to disparity in the form-function relationship for each species’ lineage. Each is notable in the manner of respective species’ jaw protrusion, as it is driven by anterior …

Assessing Undergraduate Student And Faculty Views On Animal Research: What Do They Know, Whom Do They Trust, And How Much Do They Care?, Eric P. Sandgren, Robert Streiffer, Jennifer Dykema, Nadia Assad, Jackson Moberg

Attitudes Toward Animal Research Collection

Research using animals is controversial. To develop sound public outreach and policy about this issue, we need information about both the underlying science and people’s attitudes and knowledge. To identify attitudes toward this subject at the University of Wisconsin-Madison, we developed and administered a survey to undergraduate students and faculty. The survey asked respondents about the importance of, their confidence in their knowledge about, and who they trusted to provide information on animal research. Findings indicated attitudes varied by academic discipline, especially among faculty. Faculty in the biological sciences, particularly those who had participated in an animal research project, reported …

Tracing Nutrient Sources To Lipid Production In Birds And Insects Using Stable Isotope (Δ13c, Δ2h) Tracers: Implications For Nutritional Physiology Of Migratory Species, Libesha Anparasan 2019 The University of Western Ontario

Tracing Nutrient Sources To Lipid Production In Birds And Insects Using Stable Isotope (Δ13c, Δ2h) Tracers: Implications For Nutritional Physiology Of Migratory Species, Libesha Anparasan

Electronic Thesis and Dissertation Repository

Using stable isotope measurements of inert tissues to determine origins and migratory patterns is well established. However, isotopically determining nutritional origins of lipids, the primary fuel of migration, has not been attempted. I explored isotopic links between diet and stored lipids in captive White-throated Sparrows (Zonotrichia albicollis) and true armyworm moths (Mythimna unipuncta) using δ13C and δ2H measurements. Isotopic discrimination between body lipids and diet was established as linear calibration functions. Isotopic uptake following a diet switch in moths was used to trace lipid accumulation over time. Isotopic correlations between breath metabolic …


Phenotypically Plastic Responses To Predation Risk Are Temperature Dependent, Thomas M. Luhring, Janna M. Vavra, Clayton E. Cressler, John DeLong 2019 University of Nebraska - Lincoln

Phenotypically Plastic Responses To Predation Risk Are Temperature Dependent, Thomas M. Luhring, Janna M. Vavra, Clayton E. Cressler, John Delong

School of Biological Sciences: Faculty Publications

Predicting how organisms respond to climate change requires that we understand the temperature dependence of fitness in relevant ecological contexts (e.g., with or without predation risk). Predation risk often induces changes to life history traits that are themselves temperature dependent. We explore how perceived predation risk and temperature interact to determine fitness (indicated by the intrinsic rate of increase, r) through changes to its underlying components (net reproductive rate, generation time, and survival) in Daphnia magna. We exposed Daphnia to predation cues from dragonfly naiads early, late, or throughout their ontogeny. Predation risk increased r differentially across temperatures …

Martin Stephens, PhD

The Evidence-based Toxicology Collaboration (EBTC) was established recently to translate evidence-based approaches from medicine and health care to toxicology in an organized and sustained effort. The EBTC held a workshop on “Evidence-based Toxicology for the 21st Century: Opportunities and Challenges” in Research Triangle Park, North Carolina, USA on January 24-25, 2012. The presentations largely reflected two EBTC priorities: to apply evidence-based methods to assessing the performance of emerging pathwaybased testing methods consistent with the 2007 National Research Council report on “Toxicity Testing in the 21st Century” as well as to adopt a governance structure and work processes to move that …

Stephens, Sevcan Gül Akgün-Ölmez, Sebastian Hoffman, Rob De Vries, Burkhard Flick, Thomas Hartung, Manoj Lalu, Alexandra Maertens, Hilda Witters, Robert Wright, Katya Tsaioun

Martin Stephens, PhD

Systematic review methodology is a means of addressing specific questions through structured, consistent, and transparent examinations of the relevant scientific evidence. This methodology has been used to advantage in clinical medicine, and is being adapted for use in other disciplines. Although some applications to toxicology have been explored, especially for hazard identification, the present preparatory study is, to our knowledge, the first attempt to adapt it to the assessment of toxicological test methods. As our test case, we chose the zebrafish embryotoxicity test (ZET) for developmental toxicity and its mammalian counterpart, the standard mammalian prenatal development toxicity study, focusing the …


Welfare Challenges Influence The Complexity Of Movement: Fractal Analysis Of Behaviour In Zebrafish, Anthony G. Deakin, Joseph W. Spencer, Andrew R. Cossins, Iain S. Young, Lynne U. Sneddon 2019 University of Liverpool

Welfare Challenges Influence The Complexity Of Movement: Fractal Analysis Of Behaviour In Zebrafish, Anthony G. Deakin, Joseph W. Spencer, Andrew R. Cossins, Iain S. Young, Lynne U. Sneddon

Lynne Sneddon, PhD

The ability to assess welfare is an important refinement that will ensure the good condition of animals used in experimentation. The present study investigated the impact of invasive procedures on the patterns of movement of zebrafish (Danio rerio). Recordings were made before and after fin clipping, PIT tagging and a standard pain test and these were compared with control and sham handled zebrafish. The fractal dimension (FD) from the 3D trajectories was calculated to determine the effect of these treatments on the complexity of movement patterns. While the FD of zebrafish trajectories did not differ over time in either the …


Does Environmental Enrichment Promote Recovery From Stress In Rainbow Trout?, Kieran C. Pounder, Jennifer L. Mitchell, Jack S. Thomson, Tom G. Pottinger, Jonathan Buckley, Lynne U. Sneddon 2019 University of Liverpool

Does Environmental Enrichment Promote Recovery From Stress In Rainbow Trout?, Kieran C. Pounder, Jennifer L. Mitchell, Jack S. Thomson, Tom G. Pottinger, Jonathan Buckley, Lynne U. Sneddon

Lynne Sneddon, PhD

The EU Directive on animal experimentation suggests that all protected animals should have enrichment to improve welfare yet relatively little research has been conducted on the impact of enrichment in fish. Studies employing enrichment in zebrafish have been contradictory and all fish species should be provided with species-specific enrichments relevant to their ecology. Salmonids are important experimental models in studies within aquaculture, toxicology and natural ecosystems. This study therefore sought to establish whether an enriched environment in an experimental aquarium may promote improved welfare in rainbow trout (Oncorhynchus mykiss) by enhancing their recovery from invasive procedures. Trout were …

Lynne Sneddon, PhD

Fish are used in a variety of experimental contexts often in high numbers. To maintain their welfare and ensure valid results during invasive procedures it is vital that we can detect subtle changes in behaviour that may allow us to intervene to provide pain-relief. Therefore, an automated method, the Fish Behaviour Index (FBI), was devised and used for testing the impact of laboratory procedures and efficacy of analgesic drugs in the model species, the zebrafish. Cameras with tracking software were used to visually track and quantify female zebrafish behaviour in real time after a number of laboratory procedures including fin …

Oral anticoagulants are a critical component of stroke prevention, but carry a risk of brain hemorrhage. These hemorrhagic complications tend to occur in elderly individuals, especially those with predisposing conditions such as cerebral amyloid angiopathy (CAA). Clinical evidence suggests that non-vitamin K antagonist oral anticoagulants are safer than traditional oral anticoagulants. We analyzed whether the anticoagulant dabigatran produces cerebral microhemorrhage (the pathological substrate of MRI-demonstrable cerebral microbleeds) or intracerebral hemorrhage in aged mice with and without hemorrhage-predisposing angiopathy. We studied aged (22 months old) Tg2576 (a model of CAA) and wild-type (WT) littermate mice. Mice received either dabigatran etexilate (DE) …

In November 2013, a group of international experts in animal research policy (n = 11) gathered in Vancouver, Canada, to discuss openness and accountability in animal research. The primary objective was to bring together participants from various jurisdictions (United States, Sweden, Australia, New Zealand, Germany, Canada and the United Kingdom) to share practices regarding the governance of animals used in research, testing and education, with emphasis on the governance process followed, the methods of community engagement, and the balance of openness versus confidentiality. During the forum, participants came to a broad consensus on the need for: (a) evidence-based metrics to …


Practical Considerations In Regenerative Medicine Research: Iacucs, Ethics, And The Use Of Animals In Stem Cell Studies, Susan VandeWoude, Bernard E. Rollin 2019 Colorado State University - Fort Collins

Practical Considerations In Regenerative Medicine Research: Iacucs, Ethics, And The Use Of Animals In Stem Cell Studies, Susan Vandewoude, Bernard E. Rollin

Bernard Rollin, PhD

The intent of US federal laws mandating IACUC review of animal-related activities was to satisfy contemporary socioethical concerns by introducing deliberations about ethics and animal welfare into the research process when animals are used. These laws and the system they chartered have worked well for the most part in providing opportunities for consideration of animal welfare as a vital part of animal research. As a result, investigators today are far less naïve about the ethical issues raised by research on animals and typically more sympathetic about the need for such consideration. As evidence of this growing awareness, the literature on …
