A Forensic Investigation Into The Possible Origins Of Three Human Skeletons, Jefferson P. Sinnott 2018 State University of New York College at Buffalo - Buffalo State College

A Forensic Investigation Into The Possible Origins Of Three Human Skeletons, Jefferson P. Sinnott

Forensic Science Theses

The Anthropology Department at Buffalo State has three human skeletons that have been part of the department’s collection for several years. The origin of the skeletons is currently unknown. Modern DNA techniques coupled with forensic anthropological techniques may now allow us to determine with some certainty the geographic origin of the skeletons. Ancestry, sex, age, and stature were assessed using current anthropological techniques. Afterwards, one tooth from each of the three skeletons was extracted, pulverized and DNA was isolated. Y-STR fragment size analysis of the DNA samples can provide information about the patrilineage of male individuals. Mitochondrial DNA sequencing ...


Characterization Of The Roles Of Muscle-Synthesized Brain-Derived Neurotrophic Factor And Presynaptic Tyrosine Receptor Kinase B In Motor Neuron Axonal Transport, Luke A. VanOsdol 2018 Northern Michigan University

Characterization Of The Roles Of Muscle-Synthesized Brain-Derived Neurotrophic Factor And Presynaptic Tyrosine Receptor Kinase B In Motor Neuron Axonal Transport, Luke A. Vanosdol

All NMU Master's Theses

Brain-derived neurotrophic factor (BDNF) is a small, diffusible protein essential for the development and function of neurons. It is synthesized by many types of tissue, including muscle. BDNF actions are mediated via binding to its receptor, tyrosine receptor kinase B (TrkB). The BDNF-TrkB complex is endocytosed into a specialized vesicle, which induces downstream signaling cascades locally in the dendrites, or, more often, is delivered to the cell soma via retrograde axonal transport, where it modulates gene expression. BDNF activation of TrkB is critical for the initiation of axonal transport, and this cellular process relies on the interaction of numerous adaptor ...

Mediation And Moderation Of Intergenerational Epigenetic Effects Of Trauma, Stefanie Renee Pilkay 2017 University of Tennessee, Knoxville

Mediation And Moderation Of Intergenerational Epigenetic Effects Of Trauma, Stefanie Renee Pilkay

Doctoral Dissertations

Trauma and early-life stress have been linked to poor mental and physical health outcomes. In fact, research has identified trauma and stress can influence epigenetic marks on genes that can alter gene activity. It is suspected that epigenetically altered gene activity is involved in behavior and mental health. This may help explain why some individuals don’t experience great benefit from treatment for the effects of stress, and severe mental health symptoms can be chronic for decades or a lifetime. Moreover, some trauma-related mental health symptoms have shown generational patterns that appear linked to epigenetic marks. Therefore, this study sought ...


Characterizing Mekk1: Candidate Behavioural Isolation Gene, Caryn Dooner 2017 The University of Western Ontario

Characterizing Mekk1: Candidate Behavioural Isolation Gene, Caryn Dooner

Electronic Thesis and Dissertation Repository

Behavioural isolation can occur due to divergence in aspects of courtship and mating, and can contribute to reproductive isolation. The purpose of this study is to determine how a gene, Mekk1, contributes to female rejection behaviour between D. melanogaster and D. simulans. Unique polymorphisms were identified within D. simulans Mekk1 that could contribute to behaviour, most of which are non-coding. Both transcripts of Mekk1 appear to be expressed at similar levels in D. simulans and D. melanogaster. These data also indicate that Mekk1 may be expressed in a specific region of the brain called the mushroom body, which has previously ...


Genomic Data Reveal A Loss Of Diversity In Two Species Of Tuco-Tucos (Genus Ctenomys) Following A Volcanic Eruption, Jeremy L. Hsu, Jeremy Chase Crawford, Mauro N. Tammone, Uma Ramakrishnan, Eileen A. Lacey, Elizabeth A. Hadly 2017 Chapman University

Genomic Data Reveal A Loss Of Diversity In Two Species Of Tuco-Tucos (Genus Ctenomys) Following A Volcanic Eruption, Jeremy L. Hsu, Jeremy Chase Crawford, Mauro N. Tammone, Uma Ramakrishnan, Eileen A. Lacey, Elizabeth A. Hadly

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Marked reductions in population size can trigger corresponding declines in genetic variation. Understanding the precise genetic consequences of such reductions, however, is often challenging due to the absence of robust pre- and post-reduction datasets. Here, we use heterochronous genomic data from samples obtained before and immediately after the 2011 eruption of the Puyehue-Cordón Caulle volcanic complex in Patagonia to explore the genetic impacts of this event on two parapatric species of rodents, the colonial tuco-tuco (Ctenomys sociabilis) and the Patagonian tuco-tuco (C. haigi). Previous analyses using microsatellites revealed no post-eruption changes in genetic variation in C. haigi, but an unexpected ...


Linking Taxonomic Diversity And Trophic Function: A Graph-Based Theoretical Approach, Marcella M. Jurotich, Kaitlyn Dougherty, Barbara Hayford, Sally Clark 2017 Wayne State College

Linking Taxonomic Diversity And Trophic Function: A Graph-Based Theoretical Approach, Marcella M. Jurotich, Kaitlyn Dougherty, Barbara Hayford, Sally Clark

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The purpose of this study is to develop a novel, visual method in analyzing complex functional trait data in freshwater ecology. We focus on macroinvertebrates in stream ecosystems under a gradient of habitat degradation and employ a combination of taxonomic and functional trait diversity analyses. Then we use graph theory to link changes in functional trait diversity to taxonomic richness and habitat degradation. We test the hypotheses that: 1) taxonomic diversity and trophic functional trait diversity both decrease with increased habitat degradation; 2) loss of taxa leads to a decrease in trophic function as visualized using a bipartite graph; and ...


Recognizing Challenges And Opportunities In The Quest To End Hunger, Jennifer Williams Zwagerman 2017 Texas A&M University School of Law

Recognizing Challenges And Opportunities In The Quest To End Hunger, Jennifer Williams Zwagerman

Texas A&M Law Review

As an attorney and professor that does not focus on intellectual property law, I was a bit apprehensive about providing a keynote address for a Symposium focusing on “Agriculture, Intellectual Property, and Feeding the World in the 21st Century.” As I thought about this topic, knowing that there were other speakers who would focus more on the IP issues and technical aspects of various topics, I kept coming back to the importance of technology as we worktowards the goal of feeding the world, and the many ways in which innovation plays a role in meeting that goal. It also brought ...


Accurate Cytogenetic Biodosimetry Through Automated Dicentric Chromosome Curation And Metaphase Cell Selection, Jin Liu, Yanxin Li, Ruth Wilkins, Canadian Nuclear Laboratories, Joan H. Knoll, Peter Rogan 2017 Western University

Accurate Cytogenetic Biodosimetry Through Automated Dicentric Chromosome Curation And Metaphase Cell Selection, Jin Liu, Yanxin Li, Ruth Wilkins, Canadian Nuclear Laboratories, Joan H. Knoll, Peter Rogan

Biochemistry Publications

Accurate digital image analysis of abnormal microscopic structures relies on high quality images and on minimizing the rates of false positive (FP) and negative objects in images. Cytogenetic biodosimetry detects dicentric chromosomes (DCs) that arise from exposure to ionizing radiation, and determines radiation dose received based on DC frequency. Improvements in automated DC recognition increase the accuracy of dose estimates by reclassifying FP DCs as monocentric chromosomes or chromosome fragments. We also present image segmentation methods to rank high quality digital metaphase images and eliminate suboptimal metaphase cells. A set of chromosome morphology segmentation methods selectively filtered out FP DCs ...


Examining The Neuronal Dopaminergic Pathway Underlying Sleep Behavior And Related Dopamine Sleep Disorders, Mary Beth Putz 2017 University of San Diego

Examining The Neuronal Dopaminergic Pathway Underlying Sleep Behavior And Related Dopamine Sleep Disorders, Mary Beth Putz

Undergraduate Honors Theses

The human brain is an extremely complex organ with approximately 100 billion different neurons that are constantly sending and receiving messages. These messages are sent using the chemical messengers of the brain: neurotransmitters and neuromodulators. Mechanisms of neural control of sleep are substantially conserved across species. Evidence from multiple animal models including flies, zebrafish, and mice shows that the arousal, or wake phase, is regulated by conserved neuromodulators such as dopamine, norepinephrine, and serotonin. Since these neurotransmitter systems are distributed throughout the brain and sub-serve many functions in addition to sleep, the precise circuit mechanisms by which these neurotransmitters regulate ...


Divergent Responses Of Larval And Juvenile Blue Mussels To Low Salinity Exposure, Melissa A. May 2017 University of Maine

Divergent Responses Of Larval And Juvenile Blue Mussels To Low Salinity Exposure, Melissa A. May

Electronic Theses and Dissertations

In this study, we compared the osmotic stress response of larval and juvenile blue mussels (Mytilus edulis) at the transcriptomic, metabolomic, and whole organism levels. Blue mussels inhabit coastal areas, where they face climate-induced reductions in nearshore salinity. Despite their ecological and economic importance, scientists do not fully understand the underlying transcriptomic and cellular mechanisms of the osmotic stress response in blue mussels or how the ability to respond to stress changes throughout development. Blue mussels spend the first weeks of life developing through several larval stages in the plankton. These early life history stages are more vulnerable to environmental ...
