Identifying The 5’End Of The Camta1 Genes In Zebrafish, Morgan Fronk 2018 Brigham Young University

Identifying The 5’End Of The Camta1 Genes In Zebrafish, Morgan Fronk

Undergraduate Honors Theses

Congenital heart diseases (CHDs) are a significant cause of infant death and are frequently caused by mutations in transcription factors. Camta1 (calmodulin binding transcription activator 1) is a transcription factor that has been proposed as a modulator in embryonic heart development and a possible cause of CHDs. The only other known member of its family in vertebrates is involved in activating a hypertrophy gene program in adult heart failure. Unlike camta2, camta1 is expressed in the embryonic heart during heart looping. However, few studies have been done on camta1. In zebrafish, there are two camta1 ohnologs (homologs created through a ...

Grant, Anais Martinez, Gully Apc Burns, Brendan S. Thatcher, Vishwanath T. Anekonda, Benjamin W. Thompson, Zachary S. Roberts, Daniel H. Moralejo, James E. Blevins

Arshad M. Khan, Ph.D.

This article, which includes novel unpublished data along with commentary and analysis,
focuses on approaches to link transcriptomic, proteomic, and peptidomic datasets mined from
brain tissue to the original locations within the brain that they are derived from using digital atlas
mapping techniques. We use, as an example, the transcriptomic, proteomic and peptidomic
analyses conducted in the mammalian hypothalamus. Following a brief historical overview, we
highlight studies that have mined biochemical and molecular information from the hypothalamus
and then lay out a strategy for how these data can be linked spatially to the mapped locations in a
canonical brain atlas ...


The Effect Of Diet On Craniofacial Growth In Osteogenesis Imperfecta Mouse Model, Summer H. Ladd 2018 University of North Texas Health Science Center at Fort Worth

The Effect Of Diet On Craniofacial Growth In Osteogenesis Imperfecta Mouse Model, Summer H. Ladd

Theses and Dissertations

Osteogenesis imperfecta (OI, or “brittle bone disease”) is a rare disorder that is caused by genetic point mutations (COL1A1/COL1A2) that affect type 1 collagen. In OI type III (severe) patients, limb bones are more susceptible to skeletal fractures and the bones of the craniofacial region are underdeveloped. Some OI type III patients also suffer from dental malocclusions or fractures (dentinogenesis imperfecta, DI). The goals of this project are 1) to describe the facial phenotype in an OI mouse model, to see if this model can be used to test potential behavioral and pharmaceutical interventions; and 2) to determine if ...


Pyruvate Kinase Isoform M2 Influences Autophagy And Related Processes In Hepatocellular Carcinoma Cells, Matthew Lin 2018 University of Connecticut

Pyruvate Kinase Isoform M2 Influences Autophagy And Related Processes In Hepatocellular Carcinoma Cells, Matthew Lin

University Scholar Projects

Hepatocellular carcinoma (HCC) is the most common form of liver cancer that affects ~14 million people in the world. Like all cancers, HCC is a disease that arises from unstinted cellular growth initiated by genetic alterations, metabolic changes, and dysregulation in key cellular pathways. Of interest is the relationship between metabolism and cell proliferation/degradation for therapeutic targeting. Pyruvate kinase M2 is a dimeric, glycolytically inactive isoform of the final enzyme involved in glycolysis, that is often upregulated in cancerous tissue. It is thought that the enzymatic function of PKM2 outside of glycolysis contributes to the biosynthesis of anabolic intermediates ...

Natural Resource Ecology and Management Publications

Bacterial pneumonia is a threat to bighorn sheep (Ovis canadensis) populations. Bighorn sheep in the East Humboldt Mountain Range (EHR), Nevada, USA, experienced a pneumonia epizootic in 2009–2010. Testing of mountain goats (Oreamnos americanus) that were captured or found dead on this range during and after the epizootic detected bacteria commonly associated with bighorn sheep pneumonia die‐offs. Additionally, in years subsequent to the bighorn sheep epizootic, the mountain goat population had low kid:adult ratios, a common outcome for bighorn sheep populations that have experienced a pneumonia epizootic. We hypothesized that pneumonia was present and negatively affecting mountain ...


Developing New Apparatus For In-Situ Vermicomposting And Varying Diet Parameters To Understand Optimal Conditions For Soil Fertilization., Nataliya Ryzhenko 2018 Lesley University

Developing New Apparatus For In-Situ Vermicomposting And Varying Diet Parameters To Understand Optimal Conditions For Soil Fertilization., Nataliya Ryzhenko

Lesley University Community of Scholars Day

Vermicomposting is the process of decomposing vegetable and other food waste using earthworms.

We investigate apparatus for in-situ vermicomposting and vary diet parameters to understand optimal conditions for soil fertilization.

As a pilot project, we created a small in-situ vermicomposting apparatus which can be used in a home or at a small farm. In this setting, we need to ensure that the setup does not produce repulsive odor, since it is meant to be kept indoors. Also, the setup should be easily maintained: the food waste easily added, and the bedding kept moist.

Based on results seen, in-situ vermicomposting farm ...


Addressing The Challenges Of Conducting Observational Studies In Sheep Abattoirs, Elyssa Payne, Melissa Starling, Paul McGreevy 2018 University of Sydney

Addressing The Challenges Of Conducting Observational Studies In Sheep Abattoirs, Elyssa Payne, Melissa Starling, Paul Mcgreevy

Paul McGreevy, Ph.D.

The competing needs of maintaining productivity within abattoirs, and maintaining high standards of animal welfare, provide fertile grounds for applied research in animal behavior. However, there are challenges involved in capturing useful behavioral data from the supply chain (from paddock to processing plant). The challenges identified in this report are based on a review of the scientific literature as well as field study observations. This article describes those challenges as they relate to collecting behavioral data on livestock-herding dogs, humans and livestock as they interact in abattoirs, and provides insights and recommendations for others embarking on animal studies in confined ...


Prior Voluntary Wheel Running Prevents Memory Deficits And Enhanced Neuropathic Pain Presenting After Morphine Dosing Ceases, Nathan Plattner 2018 University of Colorado, Boulder

Prior Voluntary Wheel Running Prevents Memory Deficits And Enhanced Neuropathic Pain Presenting After Morphine Dosing Ceases, Nathan Plattner

Undergraduate Honors Theses

Clinical research studies show that chronic pain is a prevalent, difficult affliction to manage. The most common management for chronic pain is opioids, which research is showing to paradoxically induce persistent, worsened pain states as well as potentially having negative effects on memory. The necessity for understanding chronic pain and drug management options is apparent, and research is aiming to do just that. Exercise is one potential preventative measure or post hoc treatment possibility for chronic pain, as abundant research has shown. Knowledge of the interactions between exercise, morphine dosing, and peripheral nerve injury is nonexistent. As such, we desired ...


Disarming “Nature” As A Weapon: A Queer Ecosemiotic Reimagining Of Futurity And Environmental Ethics Through Memoir, Sam Lauer 2018 Bucknell University

Disarming “Nature” As A Weapon: A Queer Ecosemiotic Reimagining Of Futurity And Environmental Ethics Through Memoir, Sam Lauer

Master’s Theses

In this thesis, I posit that the need for an active, conscious, and radical queering of ecocriticism as a literary and cultural theory has arisen in light of the postmodern problematization of “nature” and the “natural,” along with the queerness of society, culture, and science. The way we understand “nature” (in life and in texts), whether of physical environments, inherent selfhood, or normalcy, begs to be appropriately informed by discourses and realities of queerness in order for both social and environmental healing to take place. I have analyzed three works of queer creative nonfiction—memoirs—to illuminate the ways in ...


Possible Breakdown Of Dopamine Receptor Synergism In A Mouse Model Of Huntington's Disease, Samantha F. Kennedy 2017 University of New Orleans

Possible Breakdown Of Dopamine Receptor Synergism In A Mouse Model Of Huntington's Disease, Samantha F. Kennedy

University of New Orleans Theses and Dissertations

The model of basal ganglia function proposed by Albin, Young and Penney (1989) describes two anatomically independent motor pathways, the direct and indirect. However, under normal conditions striatal dopamine (DA) is required for the expression of motor behavior, and DAergic control of the two pathways (via D1 and D2 receptors, respectively) is dependent on co-activation. We tested for a possible breakdown of D1/D2 synergism using transgenic R6/1 mice bearing the human huntingtin allele (Htt). Motor stereotypy, observed prior to the onset of HD-related symptoms, was rated on a 5-point scale following activation of: A) D1 receptors alone, B ...


Signature Whistle Production During A Bottlenose Dolphin Group Integration, Megan S. Broadway 2017 University of Southern Mississippi

Signature Whistle Production During A Bottlenose Dolphin Group Integration, Megan S. Broadway

Dissertations

Bottlenose dolphins are an important species of interest because they possess a variety of abilities that are relatively rare in the animal kingdom, one being complex acoustic communication. Signature whistles - distinctive calls that are unique for each individual – are one of the most studied call types, but we know little about how these calls are used in various contexts, such as during an introduction. Looking at the socio-behavioral context in which signature whistles are used is likely the best way of learning how these whistles are used in a particular context (Caldwell, Caldwell, & Tyack, 1990). For this project, the behavior ...


Effects Of Trophic Relationships On Oyster Reef Restoration Success In The Mississippi Sound, Virginia Robin Fleer 2017 The University of Southern Mississippi

Effects Of Trophic Relationships On Oyster Reef Restoration Success In The Mississippi Sound, Virginia Robin Fleer

Dissertations

Natural and anthropogenic changes resulting from altered hydrology, hurricanes, variable precipitation, and the BP oil spill have all taken their toll on oyster reefs in Mississippi. In response, oyster reef restoration efforts are currently underway within the Northern Gulf of Mexico. In order to understand why these efforts succeed or fail, it is crucial to consider predator-prey relationships within the context of the trophic dynamics of oyster reefs. Thus, for this dissertation study I integrated a multidisciplinary approach to understanding key trophic interactions affecting oyster recruitment, growth and survival, comprising field sampling, manipulative lab experiments, and individual-based modeling. Spat settlement ...

Structural Insights Into The Potency Of Sk Channel Positive Modulators, Young-Woo Nam, Razan Orfali, Tingting Liu, Kunqian Yu, Meng Cui, Heike Wulff, Miao Zhang

Pharmacy Faculty Articles and Research

Small-conductance Ca2+-activated K+ (SK) channels play essential roles in the regulation of cellular excitability and have been implicated in neurological and cardiovascular diseases through both animal model studies and human genetic association studies. Over the past two decades, positive modulators of SK channels such as NS309 and 1-EBIO have been developed. Our previous structural studies have identified the binding pocket of 1-EBIO and NS309 that is located at the interface between the channel and calmodulin. In this study, we took advantage of four compounds with potencies varying over three orders of magnitude, including 1-EBIO, NS309, SKS-11 (6-bromo-5-methyl-1H-indole-2 ...

Does The Stress Inherent To Laboratory Life And Experimentation On Animals Adversely Affect Research Data?, Jarrod Bailey

Validation of Animal Experimentation

Stress and distress in laboratory animals is often inherent and unavoidable. The effect of these factors on the reliability and relevance of experimental data is not sufficiently appreciated. Greater awareness, debate and discussion of this issue are urgently required.

Spinal Cord Injury Disrupts Circadian Rhythms In Rats, Emily M. Bateman 2017 University of Colorado Boulder

Spinal Cord Injury Disrupts Circadian Rhythms In Rats, Emily M. Bateman

Psychology and Neuroscience Undergraduate Contributions

Traumatic spinal cord injury affects 282,000 people in the United States alone. Individuals often suffer from partial paralysis and chronic pain along with physiological impairments, such as abnormal thermoregulation, decreased motor function, and poor sleep quality. Current clinical therapies focus on symptomatic treatments. Despite extensive research, all of the physiologic effects and the molecular mechanism underlying spinal cord injury, and how they affect each other, remains elusive. Here, we tested whether spinal cord injury disrupted circadian rhythms, which could prolong the recovery process. We used implanted transmitters in male and female rats to measure a marker, body temperature, and ...

The hippocampus is critical for episodic memory, and synaptic changes induced by long-term potentiation (LTP) are thought to underlie memory formation. In rodents, hippocampal LTP may be induced through electrical stimulation of the perforant path. To test whether similar techniques could improve episodic memory in humans, we implemented a microstimulation technique that allowed delivery of low-current electrical stimulation via 100 μm-diameter microelectrodes. As thirteen neurosurgical patients performed a person recognition task, microstimulation was applied in a theta-burst pattern, shown to optimally induce LTP. Microstimulation in the right entorhinal area during learning significantly improved subsequent memory specificity for novel portraits; participants ...

Ependymal cilia protrude into the central canal of the brain ventricles and spinal cord to circulate the cerebral spinal fluid (CSF). Ependymal cilia dysfunction can hinder the movement of CSF leading to an abnormal accumulation of CSF within the brain known as hydrocephalus. Although the etiology of hydrocephalus was studied before, the effects of ethanol ingestion on ependymal cilia function have not been investigated in vivo. Here, we report three distinct types of ependymal cilia, type-I, type-II and type-III classified based upon their beating frequency, their beating angle, and their distinct localization within the mouse brain-lateral ventricle. Our studies show ...

Guidelines For Morpholino Use In Zebrafish, Didier Y. R. Stainier, Nathan D. Lawson, Cecilia B. Moens

Open Access Articles

The zebrafish (Danio rerio) has emerged as a powerful model to study vertebrate development and disease. Its short generation time makes it amenable to genetic manipulation and analysis, and its small size and high fecundity make it especially well suited for large-scale forward genetic and chemical screens. Fast-developing zebrafish embryos are transparent, facilitating live imaging of a variety of developmental processes in wild-type and mutant animals. ...

This brief document provides an updated set of guidelines regarding morpholino use in zebrafish that we anticipate will be of value for experimentalists as well as journal and grant reviewers, and decision makers.

Experimental In-Vivo Models Used In Fat Grafting Research For Volume Augmentation In Soft Tissue Reconstruction, Jorge Lujan-Hernandez, Raghu Appasani, Kylee Sullivan, Leah Siegel-Reamer, Janice F. Lalikos

Open Access Articles

As the popularity of fat grafting research increases, animal models are being used as the source of pre-clinical experimental information for discovery and to enhance techniques. To date, animal models used in this research have not been compared to provide a standardized model. We analyzed publications from 1968-2015 to compare published accounts of animal models in fat grafting research. Data collected included: species used, graft characteristics (donor tissue, recipient area, amount injected, injection technique), time of sacrifice and quantification methods. Mice were most commonly used (56% of studies), with the "athymic nude" strain utilized most frequently (44%). Autologous fat was ...
