New Year's Absolution, Jase Graves Dec 2017

New Year's Absolution, Jase Graves

Erma Bombeck Writers' Workshop Blog

I've never been one to make New Year's resolutions. In fact, I usually scoff at the very concept of suddenly making a decision to change some aspect of one's life, especially after a night that, for many folks, involves staying up too late and losing important articles of clothing in public. The most crucial decision these people should be making is how to navigate their way to bed without ruining the carpet. But this year, I've decided to make some significant changes, considering that it's noon on a Tuesday as I write this, and I'm still wearing pajamas.

Ultrasonic Neuromodulation In Vitro At Single Neuron Resolution, Sheikh Ilham Dec 2017

Ultrasonic Neuromodulation In Vitro At Single Neuron Resolution, Sheikh Ilham

Master's Theses

Ultrasound as a widely used imaging means for medical diagnosis has drawn growing interests as a potential noninvasive neuromodulation strategy. Focused pulsed ultrasound effectively modulates neural encoding and transmission functions especially in the peripheral nervous system (PNS) with unclear mechanism of action, which is further confounded by contradictory experimental outcomes. Lack of convincing experimental methods has hindered our mechanistic understanding of ultrasonic PNS neuromodulation. To address that, we developed a novel in vitro set up to achieve simultaneous single-unit recordings from individual mouse sciatic nerve axon and systematically studied the effect of focused pulsed ultrasound (FPUS) on action potential transmission …

ETSU Faculty Works

LIMD1 (LIM domain-containing protein 1) is considered as a tumor suppressor, being deregulated in many cancers to include hematological malignancies; however, very little is known about the underlying mechanisms of its deregulation and its roles in carcinogenesis. Epstein-Barr Virus (EBV) is associated with a panel of malignancies of lymphocytic and epithelial origin. Using high throughput expression profiling, we have previously identified LIMD1 as a common marker associated with the oncogenic transcription factor IRF4 in EBV-related lymphomas and other hematological malignancies. In this study, we have identified potential conserved IRF4- and NFκB-binding motifs in the LIMD1 gene promoter, and both are …


Comparative Genome Analysis Of Multiple Vancomycin-Resistant Enterococcus Faecium Isolated From Two Fatal Cases, S.Y. Lim, K.P. Yap, C.S.J. Teh, K.A. Jabar, Kwai Lin Thong Dec 2017

Comparative Genome Analysis Of Multiple Vancomycin-Resistant Enterococcus Faecium Isolated From Two Fatal Cases, S.Y. Lim, K.P. Yap, C.S.J. Teh, K.A. Jabar, Kwai Lin Thong

Research Publications (2016 to 2020)

Enterococcus faecium is both a commensal of the human intestinal tract and an opportunistic pathogen. The increasing incidence of enterococcal infections is mainly due to the ability of this organism to develop resistance to multiple antibiotics, including vancomycin. The aim of this study was to perform comparative genome analyses on four vancomycin-resistant Enterococcus faecium (VREfm) strains isolated from two fatal cases in a tertiary hospital in Malaysia. Two sequence types, ST80 and ST203, were identified which belong to the clinically important clonal complex (CC) 17. This is the first report on the emergence of ST80 strains in Malaysia. Three of …


Evaluating Behavioral Responses Of Nesting Lesser Snow Geese To Unmanned Aircraft Surveys, Andrew Barnas, Robert Newman, Christopher J. Felege, Michael P. Corcoran, Samuel D. Hervey, Tanner J. Stechmann, Robert F. Rockwell, Susan N. Ellis-Felege Dec 2017

Evaluating Behavioral Responses Of Nesting Lesser Snow Geese To Unmanned Aircraft Surveys, Andrew Barnas, Robert Newman, Christopher J. Felege, Michael P. Corcoran, Samuel D. Hervey, Tanner J. Stechmann, Robert F. Rockwell, Susan N. Ellis-Felege

Publications and Research

Unmanned aircraft systems (UAS) are relatively new technologies gaining popularity among wildlife biologists. As with any new tool in wildlife science, operating protocols must be developed through rigorous protocol testing. Few studies have been conducted that quantify the impacts UAS may have on unhabituated individuals in the wild using standard aerial survey protocols. We evaluated impacts of unmanned surveys by measuring UAS-induced behavioral responses during the nesting phase of lesser snow geese (Anser caerulescens caerulescens) in Wapusk National Park, Manitoba, Canada. We conducted surveys with a fixed-wing Trimble UX5 and monitored behavioral changes via discreet surveillance cameras at 25 nests. …

Oscar Brousse Jacobson: The Life And Art Of A Cosmopolitan Cultural Broker, Anne Allbright Dec 2017

Oscar Brousse Jacobson: The Life And Art Of A Cosmopolitan Cultural Broker, Anne Allbright

History Theses and Dissertations

As a graduate student studying art at Yale, Oscar Brousse Jacobson (1882–1966) pinned his career on the hopes of someday opening an art school in the American West. Jacobson was a Swedish immigrant, but he felt a deep connection to the West because he spent much of his youth on a ranch in Kansas and roamed the greater Southwest by horseback during the late 1800s. Jacobson believed that after he completed his graduate studies in New England, he would eventually return West. He planned to bring great works of art, produce his own paintings, instruct young artists, and foster art …

Cks1 Expression In Melanocytic Nevi And Melanoma, Anna A. Brożyna, Andrew Aplin, Cynthia Cohen, Grant Carlson, Andrew Joseph Page, Michael Murphy, Andrzej T. Slominski, J. Andrew Carlson

Department of Cancer Biology Faculty Papers

Cyclin-dependent kinase subunit 1 (Cks1) regulates the degradation of p27, an important G1-S inhibitor, which is up regulated by MAPK pathway activation. In this study, we sought to determine whether Cks1 expression is increased in melanocytic tumors and correlates with outcome and/or other clinicopathologic prognostic markers. Cks1 expression was assessed by immunohistochemistry in 298 melanocytic lesions. The frequency and intensity of cytoplasmic and nuclear expression was scored as a labeling index and correlated with clinico-pathological data. Nuclear Cks1 protein was found in 63% of melanocytic nevi, 89% primary and 90% metastatic melanomas with mean labeling index of 7 ± 16, …


Palm Oil: The Hidden Costs, Rachel Goehring Dec 2017

Palm Oil: The Hidden Costs, Rachel Goehring

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The growing demand for palm oil generates tens of billions of dollars in revenue and employs millions in Southeast Asian countries. The story is that conserving the rainforests from palm oil production puts this economy at risk, but only because the current formula does not account for the externalities of deforestation.


Microcredit And Survival Microenterprises: The Role Of Market Structure, P.V. Viswanath Dec 2017

Microcredit And Survival Microenterprises: The Role Of Market Structure, P.V. Viswanath

Faculty Working Papers and Articles

Poverty remains a pervasive problem all over the world, but the problem is worst in underdeveloped areas like Africa. While microfinance is supposed to address this problem through the promotion of viable businesses, it has not been very successful in helping survival microenterprises, i.e., businesses that the very poor with limited human capital have access to, in sectors with low barriers to entry and selling undifferentiated products. In this paper, I examine the role of market structure in mediating the impact of micro-lending to such survival enterprises. While there have been many evaluations of microfinance institutions (MFIs), there have been …

Does Plasticity In Thermal Tolerance Trade Off With Inherent Tolerance? The Influence Of Setal Tracheal Gills On Thermal Tolerance And Its Plasticity In A Group Of European Diving Beetles., W. C.E.P. Verberk, P. Calosi, J. I. Spicer, S. Kehl, D. T. Bilton Dec 2017

Does Plasticity In Thermal Tolerance Trade Off With Inherent Tolerance? The Influence Of Setal Tracheal Gills On Thermal Tolerance And Its Plasticity In A Group Of European Diving Beetles., W. C.E.P. Verberk, P. Calosi, J. I. Spicer, S. Kehl, D. T. Bilton

School of Biological and Marine Sciences

In the face of global warming, both the absolute thermal tolerance of an ectotherms, and its ability to shift its tolerance level via acclimation, are thought to be fundamentally important. Understanding the links between tolerance and its plasticity is therefore critical to accurately predict vulnerability to warming. Previous studies in a number of ectotherm taxa suggest trade-offs in the evolution of thermal tolerance and its plasticity, something which does not, however, apply to Deronectes diving beetles, where these traits are instead positively correlated. Here we revisit the relationship between thermal tolerance and plasticity in these beetles, paying attention to a …


Seeing Witchcraft, Bernhard Udelhoven Dec 2017

Seeing Witchcraft, Bernhard Udelhoven

Journal of Global Catholicism

When Christians in Zambia struggle with witchcraft, they also struggle with African cultural and religious concepts that deal with life’s ambiguities and that require discernment. It is not by working against the cultural and religious heritage, but by working with it, as far as possible, that the pastor can identify the broken relationships towards which many witchcraft discourses point. However, before we place the concepts of witchcraft into the realm of superstition (as are the trends of mission Christianity) or the demonic (as are the trends of charismatic Christianity), the Church has the duty to look at the concepts, stay …

Negative Impact Of Female Sex On Outcomes From Repetitive Mild Traumatic Brain Injury In Htau Mice Is Age Dependent: A Chronic Effects Of Neurotrauma Consortium Study, Scott A. Ferguson, Benoit C. Mouzon, Cillian Lynch, Carlyn Lungmus, Alexander Morin, Gogce Crynen, Benjamin Carper, Gayle Bieler, Elliott J. Mufson, William Stewart, Michael Mullan, Fiona Crawford

Translational Neuroscience

Traumatic brain injury (TBI) is a serious public health concern which strikes someone every 15 s on average in the US. Even mild TBI, which comprise as many as 75% of all TBI cases, carries long term consequences. The effects of age and sex on long term outcome from TBI is not fully understood, but due to the increased risk for neurodegenerative diseases after TBI it is important to understand how these factors influence the outcome from TBI. This study examined the neurobehavioral and neuropathological effects of age and sex on the outcome 15 days following repetitive mild traumatic brain …


Comparative Study Of Spinning Field Development In Two Species Of Araneophagic Spiders (Araneae, Mimetidae, Australomimetus), Mark A. Townley, Danilo Harms Dec 2017

Comparative Study Of Spinning Field Development In Two Species Of Araneophagic Spiders (Araneae, Mimetidae, Australomimetus), Mark A. Townley, Danilo Harms

Molecular, Cellular & Biomedical Sciences

External studies of spider spinning fields allow us to make inferences about internal silk gland biology, including what happens to silk glands when the spider molts. Such studies often focus on adults, but juveniles can provide additional insight on spinning apparatus development and character polarity. Here we document and describe spinning fields at all stadia in two species of pirate spider (Mimetidae: Australomimetus spinosus, A. djuka). Pirate spiders nest within the ecribellate orb-building spiders (Araneoidea), but are vagrant, araneophagic members that do not build prey-capture webs. Correspondingly, they lack aggregate and flagelliform silk glands (AG, FL), specialized for forming prey-capture …


Effects Of Sodium Chloride On Anthracene Photolysis Kinetics In Aqueous-Organic Solutions, Kyle Blaha Dec 2017

Effects Of Sodium Chloride On Anthracene Photolysis Kinetics In Aqueous-Organic Solutions, Kyle Blaha

Theses - ALL

Polycyclic aromatic hydrocarbons (PAHs) are dangerous pollutants. The photolysis kinetics of PAHs are of interest because they are carcinogenic and can increase in toxicity through photodegradation into secondary products. They are often associated with particulate matter. The composition and physical properties of the particulate matter can affect PAH photolysis kinetics. We investigated the effects of sodium chloride on the photolysis kinetics of the PAH anthracene in water and octanol as well as mixed-phase solutions (water-octanol), which were used as models for aqueous-organic aerosols. A non-linear dependence on sodium chloride concentrations was observed. Sodium chloride enhanced photolysis at concentrations up to …

Sanika Suvarnapathaki

Current tissue engineering therapies use macro-scale three dimensional (3D) scaffolds to treat tissue defects surgically. Uneven cell seeding and oxygen and media perfusion cause low cell viability in these macro-scale scaffolds. Microencapsulation, a technique of encapsulating cells in biocompatible polymers or hydrogels, has the potential to address these key issues, and therefore this technology has been used for numerous healthcare applications over the last two decades. Cell microencapsulation in hydrogels that mimic the tissue physiology and biochemistry has made it possible to use natural hydrogels like gelatin methacrylate …


Increased Striatal Vulnerability To 3-Nitropropionic Acid In Male, But Not Female, Mice Lacking Interleukin-1r1, Matthew Frederick Allen Dec 2017

Increased Striatal Vulnerability To 3-Nitropropionic Acid In Male, But Not Female, Mice Lacking Interleukin-1r1, Matthew Frederick Allen

Theses - ALL

Interleukin-1β (IL-1β), classically considered as a pro-inflammatory cytokine, has proven essential to cellular defense in nearly all tissues (Kaur et al., 2014, Ren and Torres, 2009). In brain, studies suggest that IL-1β has pleiotrophic effects. It acts as a neuromodulator, has been implicated in the pathogenic processes associated with a number of CNS diseases, but has also been shown to provide protection to the injured CNS. With respect to the latter, IL-1β signalling appears to mitigate pathology and motor symptoms in a mouse model of Huntington’s disease (HD), a progressive neurodegenerative condition that targets the striatum. Specifically, HD mice bred …

Concise Review: Translating Regenerative Biology Into Clinically Relevant Therapies: Are We On The Right Path?, Jennifer Simkin, Ashley W. Seifert Dec 2017

Concise Review: Translating Regenerative Biology Into Clinically Relevant Therapies: Are We On The Right Path?, Jennifer Simkin, Ashley W. Seifert

Biology Faculty Publications

Despite approaches in regenerative medicine using stem cells, bio-engineered scaffolds, and targeted drug delivery to enhance human tissue repair, clinicians remain unable to regenerate large-scale, multi-tissue defects in situ. The study of regenerative biology using mammalian models of complex tissue regeneration offers an opportunity to discover key factors that stimulate a regenerative rather than fibrotic response to injury. For example, although primates and rodents can regenerate their distal digit tips, they heal more proximal amputations with scar tissue. Rabbits and African spiny mice re-grow tissue to fill large musculoskeletal defects through their ear pinna, while other mammals fail to regenerate …

Dartmouth Scholarship

Wide local excision (WLE) of tumors with negative margins remains a challenge because surgeons cannot directly visualize the mass. Fluorescence-guided surgery (FGS) may improve surgical accuracy; however, conventional methods with direct surface tumor visualization are not immediately applicable, and properties of tissues surrounding the cancer must be considered. We developed a phantom model for sarcoma resection with the near-infrared fluorophore IRDye 800CW and used it to iteratively define the properties of connective tissues that typically surround sarcoma tumors. We then tested the ability of a blinded surgeon to resect fluorescent tumor-simulating inclusions with ∼1-cm margins using predetermined target fluorescence intensities …


Concordance And Discordance: Cognitive And Neuropsychological Performance Of Twins With Autism Spectrum Disorder, Elizabeth P. Mckernan Dec 2017

Concordance And Discordance: Cognitive And Neuropsychological Performance Of Twins With Autism Spectrum Disorder, Elizabeth P. Mckernan

Theses - ALL

This study sought to examine the cognitive and neuropsychological performance of monozygotic twin pairs who vary in concordance for ASD. The study used secondary data collected from a larger pilot study, resulting in a final sample of 28 children, all of whom were monozygotic twins (IQ range: 36 – 109). First, the study sought to determine whether pairwise concordance for ASD among monozygotic twins has changed with the use of new diagnostic criteria. McNemar tests found that pairwise concordance rates were not significantly different across DSM-IV-TR and DSM-5 diagnostic criteria, but were significantly greater with the use of either parent …

The vortex produced at the leading edge of the wing, known as the leading edge vortex (LEV), plays an important role in enhancing or destroying aerodynamic force, especially lift, upon its formation or shedding during the flapping flight of birds and insects. In this thesis, we integrate multiple new and traditional vortex identification approaches to visualize and track the LEV dynamics during its shedding process. The study is carried out using a 2D simulation of a flat plate undergoing a 45 degree pitch-up maneuver. The Eulerian 𝛤1 function and 𝑄 criterion are used along with the Lagrangian coherent structures (LCS) …


Catalytic Synthesis Of Biodiesel Fuel Under Sub/Supercritical Conditions: Kinetics And Phase Behavior, Jiuxu Liu Dec 2017

Catalytic Synthesis Of Biodiesel Fuel Under Sub/Supercritical Conditions: Kinetics And Phase Behavior, Jiuxu Liu

Dissertations - ALL

In this thesis, transesterification of triglycerides and esterification of free fatty acids were executed under subcritical and supercritical alcohol conditions, and discussed in Chapter 2-5. The project was initiated by studying the phase behavior and kinetics of transesterification reactions under severe reaction conditions (T: 300-400 oC, P=200 bar), since those conditions were suggested and commonly used in the literature. At these conditions, triglycerides reacted with alcohol within minutes, and the oil-alcohol mixture formed a homogeneous phase which minimized the boundary mass transfer resistance. The composition change of the reaction mixture made the critical point of the system approach supercritical region …
