Alternative Polyadenylation Modulates Expression Of Pro-Fibrotic Proteins And Contributes To Lung Fibrosis, Junsuk Ko 2020 The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences

Alternative Polyadenylation Modulates Expression Of Pro-Fibrotic Proteins And Contributes To Lung Fibrosis, Junsuk Ko

The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences Dissertations and Theses (Open Access)

Idiopathic pulmonary fibrosis (IPF) is a chronic lung disease which affects about 5 to 8 million individuals in the world. Despite the high prevalence, there is currently no cure for IPF, and the cause of this disease is still unclear. Our laboratory and collaborators have shown that nudix hydrolase 21 (NUDT21, which is also known as cleavage factor 25, CFIm25) is a key regulator of alternative polyadenylation (APA). NUDT21 depletion causes 3’UTR shortening via APA leading to enhanced mRNA stability and protein translation. This NUDT21 reduction promotes tumor growth in glioblastoma by enhancing expression of oncogenes. Cancer and IPF ...


Safe Sleep: Developmental Implications For Hospitalized Infants, Katherine Kohlsaat 2020 University of Rhode Island

Safe Sleep: Developmental Implications For Hospitalized Infants, Katherine Kohlsaat

Senior Honors Projects

The rate at which an infant develops both physically and cognitively is significant during sleep, as this is the time when the entire body can dedicate its efforts to this cause. Parents of healthy infants follow the guidelines set by the American Academy of Pediatrics (AAP) relating to safe sleep, and since their introduction in 1992, the rate of Sudden Infant Death Syndrome (SIDS) has decreased by 40% (Center for Disease Control and Prevention, 2016). However, if an infant has been hospitalized since birth due to necessary invasive procedures such as open-heart surgery, these protocols cannot be initially implemented. Common ...


Amygdala And Neocortical Structural Volume Analysis In The Shank3b Mutant Mouse Model Of Autism Spectrum Disorder, Preet Sawhney 2020 University of Connecticut

Amygdala And Neocortical Structural Volume Analysis In The Shank3b Mutant Mouse Model Of Autism Spectrum Disorder, Preet Sawhney

Honors Scholar Theses

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that is characterized by abnormal social behavior, deficits in communication, and motor stereotypy. The SHANK3 gene, responsible for the generation of a scaffolding protein that is integral for the development of synapses, has been identified as one of the primary candidate genes implicated in the disorder. Shank3B is the rodent homolog for this gene. Research has shown that when this gene is disrupted in rodent models (e.g., via knock-out (KO)), ASD-like behaviors result. These include deficits in social interaction, increased anxiety, and repetitive self-grooming. The current study aimed to identify a ...


Oxidative Stress Analysis Of Placental Tissue In The Rupp Pregnant Rat, Natalie Ganios 2020 The University of Akron

Oxidative Stress Analysis Of Placental Tissue In The Rupp Pregnant Rat, Natalie Ganios

Williams Honors College, Honors Research Projects

Preeclampsia is a disease associated with a vasoconstrictive phenotype due to disrupted signaling in the vascular endothelial growth factor (VEGF) relaxation pathway. The purpose of these studies is to determine the level of oxidative damage that is occurring in the placenta of the reduced uterine perfusion pressure (RUPP) rat, which serves as a common model for preeclampsia. RUPP and SHAM placenta tissue will be examined for oxidative stress as an indicator of tissue damage associated with the pathologically induced ischemia. Oxidative stress in the placental tissue will be measured by performing the following oxidative stress assays: 8-isoprostane test, TBARS assay ...


Physiological Response Of Elasmobrachs During Propofol Immersion, Matthew Levendosky 2020 Georgia Southern University

Physiological Response Of Elasmobrachs During Propofol Immersion, Matthew Levendosky

Electronic Theses and Dissertations

Sensory experiments require anesthesia so the animal is immobilized, however fish anesthetics have shown to depress sensory responses. Newer anesthetics may offer similar anesthetic relief, but differ in means of action so sensory responses may be unaffected. Propofol has been used intravenously on small elasmobranchs but may provide prolonged effects if used as an immersion anesthetic. Objectives of this study were 1. Determine appropriate concentration of anesthetic to minimize induction and recovery for animals anesthetized at a surgical plane of anesthesia and 2. Measure physiological response of the pupil to light stimuli during anesthetic immersion. To address these objectives, I ...


Towards A Hybrid Comfortable Passenger Cabin Interior For The Flying V Aircraft, Peter Vink, Thomas Rotte, Shabila Anjani, Chiara Percuoco, Roelof Vos 2020 Delft University of Technology

Towards A Hybrid Comfortable Passenger Cabin Interior For The Flying V Aircraft, Peter Vink, Thomas Rotte, Shabila Anjani, Chiara Percuoco, Roelof Vos

International Journal of Aviation, Aeronautics, and Aerospace

The Flying-V is a V-shaped airplane in development, which uses less fuel due its form. Passengers are in the oval cabin in the wing, which asks for an alternative design to the interior. At the same time there is a demand for more comfortable interiors.

80 students were asked to develop interior design ideas for this Flying V concept. A jury of experts selected four aircraft interior concepts and these were developed and a 1:1 scale mockup was made, with a hybrid interior. It included a chaise longue seats, the group space, beds and ‘staggered’ seats for the middle ...


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 by-products of fed and ...


Response Of Early Life Stage Homarus Americanus To Ocean Warming And Acidification: An Interpopulation Comparison, Maura K. Niemisto 2019 University of Maine

Response Of Early Life Stage Homarus Americanus To Ocean Warming And Acidification: An Interpopulation Comparison, Maura K. Niemisto

Electronic Theses and Dissertations

Anthropogenic carbon released into the atmosphere is driving rapid, concurrent increases in temperature and acidity across the world’s oceans, most prominently in northern latitudes. The geographic range of the iconic American lobster (Homarus americanus) spans a steep thermal gradient and one of the most rapidly warming oceanic environments. Understanding the interactive effects of ocean warming and acidification on this species’ most vulnerable early life stages is important to predict its response to climate change on a stage-specific and population level. This study compares the responses of lobster larvae from two sub-populations spanning New England’s north-south temperature gradient (southern ...

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

Western Research Forum

Using stable isotope measurements of insect tissues to determine origin and migratory patterns is well established. However, isotopically determining nutritional origins of lipids, the primary fuel of migration, has not been as thoroughly researched. We explored isotopic links between diet and stored lipids in laboratory raised True armyworm moths (Mythimna unipuncta) using δ13C and δ2H measurements. Pupae were randomly separated into four groups (n=20) and fed isotopically distinct nectar, each consisting of a combination of high δ13C (C4 sugar), or low δ13C (C3 sugar) carbohydrate, with high δ2H (deuterium ...


The Effects Of Salinity On Zootechnical Performance Of Spotted Seatrout (Cynoscion Nebulosus) In Recirculating Aquaculture Systems, Eric Gigli 2019 University of Southern Mississippi

The Effects Of Salinity On Zootechnical Performance Of Spotted Seatrout (Cynoscion Nebulosus) In Recirculating Aquaculture Systems, Eric Gigli

Master's Theses

The spotted seatrout (Cynoscion nebulosus) is a euryhaline finfish candidate for marine aquaculture in the northern Gulf of Mexico. Aquaculture of this species currently uses salinities of 25 psu or greater making production challenging in areas where high salinity water is not available. This study aimed to document the effects of salinity on zootechnical performance of spotted seatrout embryos, early larvae, and juveniles in recirculating aquaculture systems to assist with the development of protocols for low salinity culture.

Embryos obtained from a volitional spawn at 29 psu were incubated at three salinities (12.5, 18.75, or 25 psu) until ...

Thermal Biology Of Temperate And High-Latitude Arachnids, Susan E. Anthony 2019 The University of Western Ontario

Thermal Biology Of Temperate And High-Latitude Arachnids, Susan E. Anthony

Electronic Thesis and Dissertation Repository

Temperate and high latitude terrestrial ecosystems have high thermal variability, and the ectotherms that inhabit these regions must have thermal tolerances that mirror these temperatures. However, the thermal limits of many high-latitude arachnids are unknown, as well as any underlying mechanisms of seasonal plasticity for any arachnid. The objective of my thesis is to measure the thermal tolerances of temperate, Arctic, and sub-Arctic arachnids, and identify if they have thermal plasticity, either seasonally or following acclimation. I collected the high-latitude pseudoscorpion Wyochernes asiaticus streamside from the Yukon Territory, where besides large thermal variability, they are also inundated with spring flooding ...

Quantifying The Morphological And Physiological Effects Of Drought, Grass Invasion, And Fire On Longleaf, Loblolly, And Slash Pine, Laura Young 2019 Georgia Southern University

Quantifying The Morphological And Physiological Effects Of Drought, Grass Invasion, And Fire On Longleaf, Loblolly, And Slash Pine, Laura Young

Electronic Theses and Dissertations

Climate change is altering ecosystems on a global scale, creating novel ecological scenarios with which plant species must cope. Factors such as altered precipitation and fire regimes and non-native plant invasion may negatively affect native plant species, while interactions between these stressors could magnify their impacts. The complexity of multiple stressors and the effects they have on native pine seedlings are difficult to predict without evaluating their combinations in field experiments. In a multi-year study, I investigated the effects of drought and plant invasion on three southeastern pine species under pre and post-fire conditions. We planted longleaf (Pinus palustris), loblolly ...


Total Energy Intake And Self-Selected Macronutrient Distribution During Wildland Fire Suppression, Alexander N. Marks, Joseph A. Sol, Joseph W. Domitrovich, Molly R. West, Brent C. Ruby 2019 University of Montana, Missoula

Total Energy Intake And Self-Selected Macronutrient Distribution During Wildland Fire Suppression, Alexander N. Marks, Joseph A. Sol, Joseph W. Domitrovich, Molly R. West, Brent C. Ruby

Graduate Student Theses, Dissertations, & Professional Papers

Introduction: Wildland firefighters (WLFF) work long hours in extreme environments resulting in high daily total energy expenditure (TEE). Increasing work shift eating episodes and/or providing rations that promote convenient feeding has shown augmented self-selected work output, as has regular carbohydrate (CHO) consumption. It remains unclear how current WLFF feeding strategies compare to more frequent nutrient delivery. Our study’s aim was to determine WLFFs’ self-selected field total energy intake (TEI), composition, and patterns feeding during wildland fire suppression shifts.

Methods: 86 WLFF (16 female, 70 male; 27.5 ± 6.4 yr) deployed to fire incidents across the United States ...


Thermal And Low Oxygen Tolerance Of A Southern Population Of Striped Bass (Morone Saxatilis), Daniel A. Lleras 2019 Georgia Southern University

Thermal And Low Oxygen Tolerance Of A Southern Population Of Striped Bass (Morone Saxatilis), Daniel A. Lleras

Electronic Theses and Dissertations

Climate change projections estimate a 2-3°C increase in water temperatures by the end of the century. The amount of habitat with suitable temperature and oxygen concentration for aquatic organisms will also be reduced. Striped bass (Morone saxatilis) inhabiting the rivers in Southeastern Georgia make an interesting study system as they do not participate in summer coastal migrations typical of their northern conspecifics. Instead, fish in this southern population remain in freshwater environments that experience warming and decreases in dissolved oxygen. The present study aims to determine the thermal and low oxygen tolerance of juvenile striped bass collected from southeast ...


Impacts Of Ammonia And Temperature On Freshwater Snail Behavior And Physiology., Megan Christine DeWhatley 2018 University of Louisville

Impacts Of Ammonia And Temperature On Freshwater Snail Behavior And Physiology., Megan Christine Dewhatley

Electronic Theses and Dissertations

Gastropods are one of the most imperiled groups of animals in North America, yet there are major gaps in the literature pertaining to pollutants and climate change, and especially sublethal impacts. This dissertation assesses the effects of climate warming and unionized ammonia (NH3), one of the most abundant water pollutants, on the behavior and physiology of two caenogastropod snails: fine-ridged elimia (Elimia semicarinata) and Shawnee rocksnails (Lithasia obovata) (Gastropoda: Neotaenioglossa: Pleuroceridae). Righting behavior, or the movement used by snails to turn themselves right-side-up, was used as the main endpoint; delays in this behavior compromise fitness via lost feeding time ...


The Thermal Ecology Of Sceloporus Occidentalis, Luis Patricio Burgos 2018 California Polytechnic State University, San Luis Obispo

The Thermal Ecology Of Sceloporus Occidentalis, Luis Patricio Burgos

Master's Theses

With temperatures rising globally, assessing the possible impacts of the changing climate becomes more and more urgent. Ectotherms are excellent indicators of potential climatic ramifications on biodiversity because of their heavy reliance on the environment for their thermoregulation. Studies have historically looked at thermal tolerance values to establish predictive models for population and species extinctions.

In chapter 1, we looked at recent studies that suggest that thermal tolerance may be a plastic trait and test the effects empirically. Most studies are based on captive lizards acclimated to laboratory conditions that do not necessarily reflect natural environments, and if thermal tolerance ...
