A Review Of The Institute Of Medicine’S Analysis Of Using Chimpanzees In Biomedical Research, Robert C. Jones, Ray Greek 2017 California State University, Chico

A Review Of The Institute Of Medicine’S Analysis Of Using Chimpanzees In Biomedical Research, Robert C. Jones, Ray Greek

Robert C. Jones, Ph.D.

We argue that the recommendations made by the Institute of Medicine’s 2011 report, Chimpanzees in Biomedical and Behavioral Research: Assessing the Necessity, are methodologically and ethically confused. We argue that a proper understanding of evolution and complexity theory in terms of the science and ethics of using chimpanzees in biomedical research would have had led the committee to recommend not merely limiting but eliminating the use of chimpanzees in biomedical research. Specifically, we argue that a proper understanding of the difference between the gross level of examination of species and examinations on finer levels can shed light on important ...


Ivd Formation In Monodelphis Domestica, Emma C.B. Gray, Jen Maier, Karen Sears 2017 Parkland College

Ivd Formation In Monodelphis Domestica, Emma C.B. Gray, Jen Maier, Karen Sears

Phenotypic Plasticity Research Experience for Community College Students

The research summarized on this poster supports the use of the gray short-tailed opossum (Monodelphis domestica) as a lab animal for research into invertebral disc formation and degeneration. Preliminary data suggests that some genes involved in the formation and maintenance of the notochord in mice are the same in the short-tailed opossum. Data also suggests the ossification of the vertebral column of pups proceeds anteriorly to posteriorly and that much of the maturation of the nucleus puposus happens in the first ten days.


Finding A Link Between Circadian Rhythms And The Immune System Of Captive Zebra Finches (Taeniopygia Guttata), Amber Bishop 2017 Western Kentucky University

Finding A Link Between Circadian Rhythms And The Immune System Of Captive Zebra Finches (Taeniopygia Guttata), Amber Bishop

Honors College Capstone Experience/Thesis Projects

Circadian rhythms are commonplace in organisms and are normally controlled by a master clock. More recent evidence suggests that autonomous clocks operate in various systems in the body, including the immune system. This study looks for such a connection between the circadian rhythm and the immune system. In this study, captive zebra finches (Taeniopygia guttata) were exposed to different light and dark cycles and blood samples were taken every six hours. Birds were exposed to 12 hours of light and then 12 hours of darkness (LD), 24 hours of darkness (DD), or 48 hours of DD. After collecting whole blood ...


Analysis Of Population Structure In A California Newt (Taricha Torosa) Metapopulation, Jessica Vincent 2017 Western Kentucky University

Analysis Of Population Structure In A California Newt (Taricha Torosa) Metapopulation, Jessica Vincent

Honors College Capstone Experience/Thesis Projects

As anthropogenic influences take an ever-increasing toll on the environment, understanding how environmental change affects species is paramount. Concern regarding decline in amphibian populations has spurred research examining the effects of habitat change on the dynamics of populations at landscape levels. One important goal is to understand how gene flow among populations is affected by changes in habitat. Biologists need to consider the relationship between gene flow and habitat alterations so that movements among individual breeding ponds can be maintained over time, reducing risk of local extinction events. This study focuses on patterns of gene flow among thirteen populations of ...


Evaluating The Social Behavior And Activity Patterns Of Clouded Leopards (Neofelis Nebulosa) At The Nashville Zoo: Research And Literature Review, Meghan Ryckeley 2017 Western Kentucky University

Evaluating The Social Behavior And Activity Patterns Of Clouded Leopards (Neofelis Nebulosa) At The Nashville Zoo: Research And Literature Review, Meghan Ryckeley

Honors College Capstone Experience/Thesis Projects

The behavior of the elusive clouded leopard (Neofelis nebulosa) is not well understood. In captivity, they are prone to exhibit stress-related behaviors and are often aggressive to conspecifics when paired. The present study built on past research by examining clouded leopards at the Nashville Zoo at Grassmere (NZG) to determine their activity patterns and temperament. Twelve leopards were exposed to familiar and unfamiliar objects and people, as well as their reflection in a mirror over nine trials. The males were often more reactive than the females, and the 5-year olds more reactive than their younger counterparts. The mirror image and ...


Detection Of Tetracyclines In An Anaerobic Waste Digester Using Solid Phase Extraction And High-Performance Liquid Chromatography Mass Spectrometry, Courtney Cruse 2017 Western Kentucky University

Detection Of Tetracyclines In An Anaerobic Waste Digester Using Solid Phase Extraction And High-Performance Liquid Chromatography Mass Spectrometry, Courtney Cruse

Honors College Capstone Experience/Thesis Projects

Antibiotics are introduced to livestock to encourage growth and for the treatment of diseases. These antibiotics are not completely metabolized by swine, and thus these antibiotics are excreted with their waste. This poses a potential risk to human health as these antibiotics, a potential link to antibiotic resistant bacteria, then enter the surface water, ground water, and soil. In collaboration with the US Department of Agriculture (USDA) in Bowling Green, Kentucky, this research is concerned with analyzing the degradation of tetracyclines in swine waste from an anaerobic digester. Waste samples obtained from a digester and swine waste at the USDA ...


Growth And Survival Of Salamanders Exposed To Different Formulations Of Glyphosate-Based Herbicide, Jessica Johnson 2017 Western Kentucky University

Growth And Survival Of Salamanders Exposed To Different Formulations Of Glyphosate-Based Herbicide, Jessica Johnson

Honors College Capstone Experience/Thesis Projects

Amphibian populations have been experiencing rapid declines worldwide in the past few decades. There are many proposed causations, including the use of agricultural chemicals such as herbicides. Glyphosate based herbicides are one of the most widely used herbicides. This study looks at the effects of different brands of glyphosate-based herbicides, including those intended for aquatic use, on the survival and growth of axolotl salamander larvae. Out of four brands of glyphosate herbicide (Aquamaster, Aquaneat, Helosate plus, and Roundup Pro), the survival rates of Roundup Pro were the lowest. Most mortality occurred between the 3 mg/L and 6 mg/L ...


Characterization Of An 18f-Growth Hormone Secretagogue Probe For Positron Emission Tomography Imaging Of The Growth Hormone Secretagogue Receptor, Ahmed Abbas 2017 The University of Western Ontario

Characterization Of An 18f-Growth Hormone Secretagogue Probe For Positron Emission Tomography Imaging Of The Growth Hormone Secretagogue Receptor, Ahmed Abbas

Electronic Thesis and Dissertation Repository

Cardiovascular disease affects 1.6 million Canadians, of whom one-third have heart failure (HF). HF is diagnosed by imaging investigations and detection of circulating biomarkers. Most of the current imaging strategies study morphologic and gross functional changes, but fall short of imaging molecular abnormalities associated with HF. Biomarkers offer molecular targets; however, clinical biomarkers circulate systemically and are not cardiac-specific. Thus, there is critical need for a biomarker that is endogenous to myocardial tissues. The growth hormone secretagogue receptor 1a (GHSR1a), which binds the hormone ghrelin, is expressed by cardiomyocytes and is elevated in HF patients. This study characterized the ...


Investigation Into The Mechanism Of Ion Transport In Rio Negro Characiformes, Vineza D. Reduta 2017 University of San Diego

Investigation Into The Mechanism Of Ion Transport In Rio Negro Characiformes, Vineza D. Reduta

Undergraduate Honors Theses

Four fish species within the Characiform Order [(Rosy tetras (Hyphessobrycon rosaceus), Serpae tetras (Hyphessobrycon eques), Emperor tetras (Nematobrycon palmeri) and Penguin tetras (Thayeria obliqua)] are native to the ion-poor, acidic waters of the Rio Negro. In this paper, we focus on Wood’s revised Na+/NH4+ exchange model to gain better insight into the mechanisms of ion transport within the Characids. We exposed each species to two experimental treatments: (i) 1mM ammonia (high external ammonia [HEA]), to test coupling of Na+ uptake and ammonia excretion, and (ii) 100μM Acetazolamide (carbonic anhydrase inhibitor), to test coupling of Na+ uptake and ...


Measuring Fertilization In Populations Of Sea Scallop (Placopecten Magellanicus): Developing And Testing Methods In The Laboratory And Field, Skylar Bayer 2017 University of Maine

Measuring Fertilization In Populations Of Sea Scallop (Placopecten Magellanicus): Developing And Testing Methods In The Laboratory And Field, Skylar Bayer

Electronic Theses and Dissertations

Most marine organisms are broadcast spawners, releasing their sperm and eggs into the water column. Methods of measuring in situ fertilization have proven successful with a few model species, which are reviewed in my introductory chapter. However, many commercially exploited species, such as the sea scallop Placopecten magellanicus, have been neglected. Sea scallop populations have greatly increased from fishing closures, but the mechanism behind this response is uncertain, particularly in regard to fertilization. In this dissertation I developed a methodology of measuring fertilization success and spawning events of P. magellanicus, tested it in laboratory and field settings, and developed a ...


Functional Analysis And Treatment Of Self-Injurious Feather Plucking In A Black Vulture (Coragyps Atratus), Kristen L. Morris 2017 Rollins College

Functional Analysis And Treatment Of Self-Injurious Feather Plucking In A Black Vulture (Coragyps Atratus), Kristen L. Morris

Thesis Projects

Feather plucking (FP) is a maladaptive behavior observed in captive avian species. This self-injurious behavior results in damage to and removal of feathers and skin tissue, resulting in animal welfare and financial consequences. The etiology and maintenance of FP have been hypothesized through medical and environmental processes, yet a definitive solution has not been found. The current study investigated the environmental variables maintaining the FP of a Black Vulture (Coragyps atratus), as well as evaluated a function-based treatment for this behavior. The behavior was found to be maintained by positive reinforcement in the form of contingent attention. Treatment consisted of ...


Does Genotype Correlate With Phenotype? Evaluating Ruffed Lemur (Varecia Spp.) Color Vision Using Subject Mediated Automatic Remote Testing Apparatus (Smarta), Raymond Vagell 2017 CUNY Hunter College

Does Genotype Correlate With Phenotype? Evaluating Ruffed Lemur (Varecia Spp.) Color Vision Using Subject Mediated Automatic Remote Testing Apparatus (Smarta), Raymond Vagell

School of Arts & Sciences Theses

Ruffed lemur (Varecia spp.) color vision research was conducted using a multidisciplinary approach: psychophysics, genetic analysis, technology, and animal training. The behavioral manifestation of Varecia spp. trichromacy was shown using a touchscreen apparatus (SMARTA). Trichromats performed better than dichromats when discriminating red from green (G2 = 78.10, p < 0.001).


Lymphoid Hematopoiesis And The Role Of B-Cells In Transgenic Mouse Model Of Sickle Cell Disease, Christina Cotte 2017 University of Connecticut - Storrs

Lymphoid Hematopoiesis And The Role Of B-Cells In Transgenic Mouse Model Of Sickle Cell Disease, Christina Cotte

University Scholar Projects

Sickle cell disease (SCD) has been shown to be associated with decreased baseline immunity and thus increased susceptibility to infection. I sought to discern possible causes of this by looking into the correlations between SCD and hematopoiesis, the immune system and the neuroendocrine system, and ultimately by conducting experiments surrounding the impaired immune system of SCD. These experiments focused on the potential causes and effects of the diminution of B-1a cells in the SCD spleen. Adoptive transfers, infections with Streptococcus pneumoniae, and histologic imaging were conducted to establish if the diminution of the B-1a cells in the SCD spleen is ...


In Vitro Studies On Metabolism Of Salvinorin A, Lukasz M. Kutrzeba, Vardan T. Karamyan, Robert C. Speth, John S. Williamson, Jordan K. Zjawiony 2017 University of Mississippi

In Vitro Studies On Metabolism Of Salvinorin A, Lukasz M. Kutrzeba, Vardan T. Karamyan, Robert C. Speth, John S. Williamson, Jordan K. Zjawiony

John S. Williamson

Microbial transformation of natural products is a well established model for mammalian metabolism. Salvinorin A, a diterpenoid isolated from the hallucinogenic mint Salvia divinorum Epling & Játiva-M (Lamiaceae), is a potent non-nitrogenous κ-opioid receptor agonist. The metabolism of salvinorin A has still not yet been well established. Thirty fungal species were screened for the ability to metabolize salvinorin A. We observed that salvinorin A undergoes fast hydrolysis of the acetate group at carbon atom C2, resulting in formation of the pharmacologically inactive product, salvinorin B. Ex vivo experiments were also performed using organelle fractions isolated from rat liver and brain. Crude ...


The Effects Of Methamphetamine Exposure On Cardiovascular Development In Combination With Hypoxia In Danio Rerio, Sarah Donaldson 2017 University of Akron

The Effects Of Methamphetamine Exposure On Cardiovascular Development In Combination With Hypoxia In Danio Rerio, Sarah Donaldson

Honors Research Projects

The purpose of this study was to determine the effects of methamphetamine combined with hypoxia on the development and function of the cardiovascular system in Danio rerio embryos. It was hypothesized that the combined effect of the drug and decreased oxygen concentration would result in decreased cardiac parameters due to underdevelopment of the ventricle and vessels resulting from cardiomyopathy and lack of blood flow to tissues. It was found that methamphetamine exposure correlated to an increase in stroke volume, caudal artery and vein diameters and RBC velocities alone, while having a multiplicative effect of increasing arterial RBC velocity when combined ...


Animal Sentience And The Precautionary Principle, Jonathan Birch 2017 London School of Economics and Political Science

Animal Sentience And The Precautionary Principle, Jonathan Birch

Animal Sentience: An Interdisciplinary Journal on Animal Feeling

In debates about animal sentience, the precautionary principle is often invoked. The idea is that when the evidence of sentience is inconclusive, we should “give the animal the benefit of the doubt” or “err on the side of caution” in formulating animal protection legislation. Yet there remains confusion as to whether it is appropriate to apply the precautionary principle in this context, and, if so, what “applying the precautionary principle” means in practice regarding the burden of proof for animal sentience. Here I construct a version of the precautionary principle tailored to the question of animal sentience together with a ...


Mammary Extracellular Matrix Directs Differentiation Of Testicular And Embryonic Stem Cells To Form Functional Mammary Glands In Vivo, Robert D. Bruno, Jodie M. Fleming, Andrea L. George, Corinne A. Boulanger, Pepper Schedin, Gilbert H. Smith 2017 Old Dominion University

Mammary Extracellular Matrix Directs Differentiation Of Testicular And Embryonic Stem Cells To Form Functional Mammary Glands In Vivo, Robert D. Bruno, Jodie M. Fleming, Andrea L. George, Corinne A. Boulanger, Pepper Schedin, Gilbert H. Smith

Medical Diagnostics & Translational Sciences Faculty Publications

Previously, we demonstrated the ability of the normal mammary microenvironment (niche) to direct non-mammary cells including testicular and embryonic stem cells (ESCs) to adopt a mammary epithelial cell (MEC) fate. These studies relied upon the interaction of transplanted normal MECs with non-mammary cells within the mammary fat-pads of recipient mice that had their endogenous epithelium removed. Here, we tested whether acellular mammary extracellular matrix (mECM) preparations are sufficient to direct differentiation of testicular-derived cells and ESCs to form functional mammary epithelial trees in vivo. We found that mECMs isolated from adult mice and rats were sufficient to redirect testicular derived ...


An Assessment Of The Role Of Chimpanzees In Aids Vaccine Research, Jarrod Bailey 2016 New England Anti-Vivisection Society

An Assessment Of The Role Of Chimpanzees In Aids Vaccine Research, Jarrod Bailey

Jarrod Bailey, Ph.D.

Prior to Simian Immunodeficiency Virus (SIV)-infected macaques becoming the ‘model of choice’ in the 1990s, chimpanzees were widely used in AIDS vaccine research and testing. Faced with the continued failure to develop an effective human vaccine, some scientists are calling for a return to their widespread use. To assess the past and potential future contribution of chimpanzees to AIDS vaccine development, databases and published literature were systematically searched to compare the results of AIDS vaccine trials in chimpanzees with those of human clinical trials, and to determine whether the chimpanzee trials were predictive of the human response. Protective and ...


Lessons From Chimpanzee-Based Research On Human Disease: The Implications Of Genetic Differences, Jarrod Bailey 2016 New England Anti-Vivisection Society

Lessons From Chimpanzee-Based Research On Human Disease: The Implications Of Genetic Differences, Jarrod Bailey

Jarrod Bailey, Ph.D.

Assertions that the use of chimpanzees to investigate human diseases is valid scientifically are frequently based on a reported 98–99% genetic similarity between the species. Critical analyses of the relevance of chimpanzee studies to human biology, however, indicate that this genetic similarity does not result in sufficient physiological similarity for the chimpanzee to constitute a good model for research, and furthermore, that chimpanzee data do not translate well to progress in clinical practice for humans. Leading examples include the minimal citations of chimpanzee research that is relevant to human medicine, the highly different pathology of HIV/AIDS and hepatitis ...


An Analysis Of The Use Of Dogs In Predicting Human Toxicology And Drug Safety, Jarrod Bailey, Michelle Thew, Michael Balls 2016 British Union for the Abolition of Vivisection

An Analysis Of The Use Of Dogs In Predicting Human Toxicology And Drug Safety, Jarrod Bailey, Michelle Thew, Michael Balls

Jarrod Bailey, Ph.D.

Dogs remain the main non-rodent species in preclinical drug development. Despite the current dearth of new drug approvals and meagre pipelines, this continues, with little supportive evidence of its value or necessity. To estimate the evidential weight provided by canine data to the probability that a new drug may be toxic to humans, we have calculated Likelihood Ratios (LRs) for an extensive dataset of 2,366 drugs with both animal and human data, including tissue-level effects and Medical Dictionary for Regulatory Activities (MedDRA) Level 1–4 biomedical observations. The resulting LRs show that the absence of toxicity in dogs provides ...
