description: The aim of the paper is to provide a solution which increases the security of a mobile environment for both individuals and for workers in an enterprise. The proposed solution adapts Shamir's approach for sharing a secret for encryption key management. One part of the key is stored on a Bluetooth (or NFC) wristband or on an enterprise server, while a mobile device is used to store all the rest. The approach can be applied for both securing documents and voice data. The solution is supported by a mathematical formality which is missing in the currently known advice within cryptographic folklore.

description: We present a dynamical analysis to infer the structural parameters and properties of the two nearby, compact, high velocity dispersion galaxies MRK1216 & NGC1277. Combining deep HST imaging, wide-field IFU stellar kinematics, and complementary long-slit spectroscopic data out to 3 R_e, we construct orbit-based models to constrain their black hole masses, dark matter content and stellar mass-to-light ratios. We obtain a black hole mass of log(Mbh/Msun) = 10.1(+0.1/-0.2) for NGC1277 and an upper limit of log(Mbh/Msun) = 10.0 for MRK1216, within 99.7 per cent confidence. The stellar mass-to-light ratios span a range of Upsilon_V = 6.5(+1.5/-1.5) in NGC1277 and Upsilon_H = 1.8(+0.5/-0.8) in MRK1216 and are in good agreement with SSP models of a single power-law Salpeter IMF. Even though our models do not place strong constraints on the dark halo parameters, they suggest that dark matter is a necessary ingredient in MRK1216, with a dark matter contribution of 22(+30/-20) per cent to the total mass budget within 1 R_e. NGC1277, on the other hand, can be reproduced without the need for a dark halo, and a maximal dark matter fraction of 13 per cent within the same radial extent. In addition, we investigate the orbital structures of both galaxies, which are rotationally supported and consistent with photometric multi-Sérsic decompositions, indicating that these compact objects do not host classical, non-rotating bulges formed during recent (z <= 2) dissipative events or through violent relaxation. Finally, both MRK 1216 and NGC 1277 are anisotropic, with a global anisotropy parameter delta of 0.33 and 0.58, respectively. While MRK 1216 follows the trend of fast-rotating, oblate galaxies with a flattened velocity dispersion tensor in the meridional plane of the order of beta_z = delta, NGC 1277 is highly tangentially anisotropic and seems to belong kinematically to a distinct class of objects.

description: The James Webb Space Telescope (JWST), scheduled for launch in 2018, is the successor to the Hubble Space Telescope (HST) but with a significantly larger aperture (6.5 m) and advanced instrumentation focusing on infrared science (0.6-28.0 $μ$m ). In this paper we examine the potential for scientific investigation of Titan using JWST, primarily with three of the four instruments: NIRSpec, NIRCam and MIRI, noting that science with NIRISS will be complementary. Five core scientific themes are identified: (i) surface (ii) tropospheric clouds (iii) tropospheric gases (iv) stratospheric composition and (v) stratospheric hazes. We discuss each theme in depth, including the scientific purpose, capabilities and limitations of the instrument suite, and suggested observing schemes. We pay particular attention to saturation, which is a problem for all three instruments, but may be alleviated for NIRCam through use of selecting small sub-arrays of the detectors - sufficient to encompass Titan, but with significantly faster read-out times. We find that JWST has very significant potential for advancing Titan science, with a spectral resolution exceeding the Cassini instrument suite at near-infrared wavelengths, and a spatial resolution exceeding HST at the same wavelengths. In particular, JWST will be valuable for time-domain monitoring of Titan, given a five to ten year expected lifetime for the observatory, for example monitoring the seasonal appearance of clouds. JWST observations in the post-Cassini period will complement those of other large facilities such as HST, ALMA, SOFIA and next-generation ground-based telescopes (TMT, GMT, EELT).

The Effects of the Flow State on Social Orientation Within and Beyond Group Boundaries
Creators: name: Tepper, Stephanie J.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Research on flow, a positive emotional experience characterized by full absorption, involvement,
and enjoyment during an activity, has primarily focused on the individual benefits of this mental
state. In the present study, I investigate the mechanisms by which flow may produce changes in
social orientation such that the boundaries between the self and other are diminished. In a 2x2
study, UNC undergraduates (N=106) were randomly assigned to a flow or no flow condition;
half of the participants were also randomly assigned to have a mirror in the cubicle during the
study to manipulate self-consciousness. I hypothesized that flow would alter social orientation
such that people reported increased feelings of closeness with others, mediated by decreases on
self-consciousness. Contrary to hypotheses, primary analyses demonstrated no significant effects
of condition on average measures of social closeness, although participants in the flow and
mirror conditions reported the highest feelings of closeness with others on individual items from
two measures of interpersonal closeness. Further, participants in the flow and mirror condition
also exhibited higher levels of state mindfulness. This work implies that the flow state should be
conceptualized and researched in terms of the potential social benefits of decreasing boundaries
between individuals.

description: We compare the standard 50%-efficient single beam splitter method for Bell-state measurement to a proposed 75%-efficient auxiliary-photon-enhanced scheme [W. P. Grice, Phys. Rev. A 84, 042331 (2011)] in light of realistic conditions. The two schemes are compared with consideration for high input state photon loss, auxiliary state photon loss, detector inefficiency and coupling loss, detector dark counts, and non-number-resolving detectors. We also analyze the two schemes when multiplexed arrays of non-number-resolving detectors are used. Furthermore, we explore the possibility of utilizing spontaneous parametric down-conversion as the auxiliary photon pair source required by the enhanced scheme. In these different cases, we determine the bounds on the detector parameters at which the enhanced scheme becomes superior to the standard scheme and describe the impact of the different imperfections on measurement success rate and discrimination fidelity. This is done using a combination of numeric and analytic techniques. For many of the cases discussed, the size of the Hilbert space and the number of measurement outcomes can be very large, which makes direct numerical solutions computationally costly. To alleviate this problem, all of our numerical computations are performed using pure states. This requires tracking the loss modes until measurement and treating dark counts as variations on measurement outcomes rather than modifications to the state itself. In addition, we provide approximate analytic expressions that illustrate the effect of different imperfections on the Bell-state analyzer quality.

description: Der aktuelle Trend im Umfeld von Modellierungstools geht weg von monolithischen Desktop Applikationen und hin zu Applikationen, die über die Cloud verfügbar sind.Die unterschiedlichen Editoren solcher Tools sollten unabhängig voneinander agieren, was bedeutet, dass eine direkte Kommunikation zwischen diesen Services nicht vorgesehen ist. Diese Services sollten wiederverwendbar und erweiterbar bleiben, um alle Vorteile von Micro Services zu gewährleisten.Dennoch müssen diese unabhängigen Editoren und deren Services das mit gemeinsamen Modellen und das Editieren möglicherweise überlappenden Modellteile unterstützen.Diese Arbeit versucht diese Problemstellung zu lösen, in dem eine zentrale Komponente eingeführt wird, die für die gesamte Modelverwaltung zuständig ist, und dabei auch zentral und leicht zugänglich sein wird.Damit soll auch gewährleistet werden, dass die verschiedenen Editoren, die von Anwenderinnen und Anwendern gleichzeitig bedient werden können, das darunter liegende Model gleichzeitig bearbeiten können.Es werden die Anforderungen für eine solche Komponente definiert, gefolgt von der Implementierung verschiedener Editoren, die direkt mit der neuen Verwaltungskomponente interagieren können.Abschließend, um das Resultat dieser Arbeit zu bewerten, werden die neue Komponente sowie die Editoren in ein Modellierungstool eingebunden. Dies ermöglicht einen direkten Vergleich mit existierenden Desktop-Anwendungen.
description: Currently, many modeling toolchains are moving from monolithic desktop applications to cloud-based solutions.The involved editors of those tools should be operating independently from one another, which means direct communication between those services is not allowed. This is because, that those micro services should stay reusable and extensible.However, at the same time these independent editors and their supporting micro services should operate on common models and allow to manipulate potentially overlapping parts of the underlying models.This thesis aims to solve this problem, by introducing an independent component, that is able to manage the entire model handling, whilst being centralized and easily accessible.It also has to ensure the interoperability of multiple editors used by one user at a time to manipulate an underlying model.The requirements for such an artifact are researched and defined in the scope of this thesis.To demonstrate the artifact, editing capabilities that work with the newly introduced model management component are implemented.Finally, to evaluate the artifacts, the managing component as well as the editing components are integrated in a web-based editor project which is directly comparable to an existing desktop application.

description: To address the complexity of Reunification, this thesis focuses on the three phases of German Reunification, giving the reader a full picture of women’s lives before, during, and after Reunification. Watching the transition unfold makes it clear that we cannot simply categorize women as winners or losers. It is important to study East German women twenty-five years after Reunification because the level of analysis of Reunification’s effects in regards to women was high directly after Reunification soon tapered off.

description: We demonstrate, using first-principles calculations, that the electronic structure of FeSe$_{1-x}$Te$_{x}$ ($x$=0.5) is topologically non-trivial, characterized by an odd $\mathbb Z_2$ invariant and Dirac cone type surface states, in sharp contrast to the end member FeSe ($x$=0). This topological state is induced by the enhanced three-dimensionality and spin-orbit coupling due to Te substitution (compared to FeSe), characterized by a band inversion at the $Z$ point of the Brillouin zone, which is confirmed by our ARPES measurements. The results suggest that the surface of FeSe$_{0.5}$Te$_{0.5}$ may support a non-trivial superconducting channel in proximity to the bulk.

The condensed scalar mixes charged and neutral fields dual to composite fermionic operators in the Dirac equations. Both gapped and gapless bands of stable quasiparticles are found.

description: We extend classical Propositional Logic (PL) by adding a new primitive binary connective $φ|ψ$, intended to represent the "superposition" of sentences $φ$ and $ψ$, an operation motivated by the corresponding notion of quantum mechanics, but not intended to capture all aspects of the latter as they appear in physics. To interpret the new connective, we extend the classical Boolean semantics by employing models of the form $\langle M,f\rangle$, where $M$ is an ordinary two-valued assignment for the sentences of PL and $f$ is a choice function for all pairs of classical sentences. In the new semantics $φ|ψ$ is strictly interpolated between $φ\wedgeψ$ and $φ\veeψ$. By imposing several constraints on the choice functions we obtain corresponding notions of logical consequence relations and corresponding systems of tautologies, with respect to which $|$ satisfies some natural algebraic properties such as associativity, closedness under logical equivalence and distributivity over its dual connective. Thus various systems of Propositional Superposition Logic (PLS) arise as extensions of PL. Axiomatizations for these systems of tautologies are presented and soundness is shown for all of them. Completeness is proved for the weakest of these systems. For the other systems completeness holds if and only if every consistent set of sentences is extendible to a consistent and complete one, a condition whose truth is closely related to the validity of the deduction theorem.

description: Allosteric (long-range) interactions can be surprisingly strong in proteins of biomedical interest. Here we use bioinformatic scaling to connect prior results on nonsteroidal anti-inflammatory drugs to promising new drugs that inhibit cancer cell metabolism. Many parallel features are apparent, which explain how even one amino acid mutation, remote from active sites, can alter medical results. The enzyme twins involved are cyclooxygenase (aspirin) and isocitrate dehydrogenase (IDH). The IDH results are accurate to 1% and are overdetermined by adjusting a single bioinformatic scaling parameter. It appears that the final stage in optimizing protein functionality may involve leveling of the hydrophobic cutoffs of the arms of conformational hydrophilic hinges.

description: Colossal two-phase Liquid Argon Time Projection Chambers (LAr TPCs) are a proposed option for future long-baseline neutrino experiments. This study illustrates the feasibility of using an EMCCD camera to capture light induced by single cosmic events in a two-phase LAr TPC employing a THGEM. An Andor iXon Ultra 897 EMCCD camera was externally mounted via a borosilicate glass viewport on the Liverpool two-phase LAr TPC. The camera successfully captured the secondary scintillation light produced at the THGEM holes that had been induced by cosmic events. The light collection capability of the camera for various EMCCD gains was assessed. For a THGEM gain of 64 and an EMCCD gain of 1000, clear images were captured with an average signal-to-noise ratio of 6. Preliminary 3D reconstruction of straight cosmic muon tracks has been performed by combining the camera images, PMT signals and THGEM charge data. Reconstructed cosmic muon tracks were used to determine THGEM gain and to calibrate the intensity levels of the EMCCD image.
An End-to-End Framework For Universal Lesion Detection With Missing Annotations

description: Fully annotated large-scale medical image datasets are highly valuable. However, because labeling medical images is tedious and requires specialized knowledge, the large-scale datasets available often have missing annotation issues. For instance, DeepLesion, a large-scale CT image dataset with labels for various kinds of lesions, is reported to have a missing annotation rate of 50\%. Directly training a lesion detector on it would suffer from false negative supervision caused by unannotated lesions. To address this issue, previous works have used sophisticated multi-stage strategies to switch between lesion mining and detector training. In this work, we present a novel end-to-end framework for mining unlabeled lesions while simultaneously training the detector. Our framework follows the teacher-student paradigm. In each iteration, the teacher model infers the input data and creates a set of predictions. High-confidence predictions are combined with partially-labeled ground truth for training the student model. On the DeepLesion dataset, using the original partially labeled training set, our model can outperform all other more complicated methods and surpass the previous best method by 2.3\% on average sensitivity and 2.7\% on average precision, achieving state-of-the-art universal lesion detection results.
Developing and Verifying Fluorescent Constructs For Observing p27 Dynamics in Mammalian Cells
Creators: name: Kiserow, Deborah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: The cell cycle is a highly controlled mechanism composed of G1, S, G2, and M phases,
with the transitions between these phases regulated in part by cyclin dependent kinases
(CDKs). CDK inhibitors (CKIs) including p21 and p27 are key proteins that arrest the cell in G1
to prevent division when the cell is under stress or possesses DNA damage. Additionally, p27
expression is upregulated in quiescence (G0), when the cell is not actively cycling. p27 is
targeted for degradation at the G0/G1 transition, and again at the G1/S transition when p21 is
also degraded, though the order of cell cycle protein degradation at G1/S, and its impact on
normal cell proliferation, is unknown. The purpose of this study is to develop a fusion protein
biosensor that mirrors endogenous p27 expression in mammalian cells.

description: Analyses and applications based on bibliographic references are of ever increasing importance. However, reference linking methods described in the literature are only able to link around half of the references in papers. To improve the quality of reference linking in large scholarly data sets, we propose a blocking-based reference linking approach that utilizes a rich set of reference fields (title, author, journal, year, etc.) and is independent of a target collection of paper records to be linked to. We evaluate our approach on a corpus of 300,000 references. Relative to the original data, we achieve a 90% increase in papers linked through references, a five-fold increase in bibliographic coupling, and a nine-fold increase in in-text citations covered. The newly established links are of high quality (85% F1).
Development of an engineered skin substitute for the treatment of burn injuries

Subjects: Biomaterials

description: Skin is the largest organ in the body and it acts as a barrier between the internal body organs and the external environment. Thus, it is more susceptible to injury than any other organ. Although there are several skin substitutes available there is no single one that is used as a standard treatment, because most substitutes lack one or two essential properties that make the best clinical outcome. Here we explore the possibility of improving on currently available skin substitutes by designing a composite material (hydrogel in a porous carrier) to help with healing full thickness and partial thickness burn wounds.

description: We investigate how the sentence choice semantics (SCS) for propositional superposition logic (PLS) developed in \cite{Tz17} could be extended so as to successfully apply to first-order superposition logic(FOLS). There are two options for such an extension. The apparently more natural one is the formula choice semantics (FCS) based on choice functions for pairs of arbitrary formulas of the basis language. It is proved however that the universal instantiation scheme of FOL, $(\forall v)φ(v)\rightarrowφ(t)$, is false, as a scheme of tautologies, with respect to FCS. This causes the total failure of FCS as a candidate semantics. Then we turn to the other option which is a variant of SCS, since it uses again choice functions for pairs of sentences only. This semantics however presupposes that the applicability of the connective $|$ is restricted to quantifier-free sentences, and thus the class of well-formed formulas and sentences of the language is restricted too. Granted these syntactic restrictions, the usual axiomatizations of FOLS turn out to be sound and conditionally complete with respect to this second semantics, just like the corresponding systems of PLS.

Body Image in Adolescent Males: Body Dissatisfaction as a Moderator of Drive for Muscularity and Depression
Creators: name: Staples, Cody
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Most research examining the correlates and outcomes associated with body image has focused on female populations, but there has been a recent emphasis on studying body image in males.  Drive for muscularity, which examines whether or not a person desires to gain muscle mass, is an important construct to analyze during the assessment of male body image.  The current study analyzed associations among drive for muscularity, body dissatisfaction, and depressive symptoms within a sample of adolescent males.  Drive for muscularity was positively correlated to body dissatisfaction and depressive symptoms at a single time point, supporting findings from previous studies.  A significant interaction effect suggested that body dissatisfaction moderated the relationship between drive for muscularity and depressive symptoms over time.  The current study adds to existing literature regarding male body image by suggesting that the relationship between drive for muscularity and body dissatisfaction can provide insight on future negative outcomes.

description: We report detections of two candidate distant submillimeter galaxies (SMGs), MM J154506.4$-$344318 and MM J154132.7$-$350320, which are discovered in the AzTEC/ASTE 1.1 mm survey toward the Lupus-I star-forming region. The two objects have 1.1 mm flux densities of 43.9 and 27.1 mJy, and have Herschel/SPIRE counterparts as well. The Submillimeter Array counterpart to the former SMG is identified at 890 $μ$m and 1.3 mm. Photometric redshift estimates using all available data from the mid-infrared to the radio suggest that the redshifts of the two SMGs are $z_{\rm photo} \simeq$ 4-5 and 3, respectively. Near-infrared objects are found very close to the SMGs and they are consistent with low-$z$ ellipticals, suggesting that the high apparent luminosities can be attributed to gravitational magnification. The cumulative number counts at $S_{\rm 1.1mm} \ge 25$ mJy, combined with other two 1.1-mm brightest sources, are $0.70 ^{+0.56}_{-0.34}$ deg$^{-2}$, which is consistent with a model prediction that accounts for flux magnification due to strong gravitational lensing. Unexpectedly, a $z > 3$ SMG and a Galactic dense starless core (e.g., a first hydrostatic core) could be similar in the mid-infrared to millimeter spectral energy distributions and spatial structures at least at $\gtrsim 1"$. This indicates that it is necessary to distinguish the two possibilities by means of broad band photometry from the optical to centimeter and spectroscopy to determine the redshift, when a compact object is identified toward Galactic star-forming regions.

The Longitudinal Mutual Influence Model of Social Norms Perceptions and Risky Alcohol Use
Creators: name: Giordano, Michael L.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: Past research has shown that college students consistently misperceive the amount of alcohol that
their peers consume; consistent with theories of peer influence, this misperception is associated
with personal use of alcohol. Few studies to date have used a longitudinal design in order to test
changes over time as well as a model of mutual influence between alcohol use and social norms
perceptions. A representative sample of 889 UNC students completed survey questionnaires
during their summer orientation, again four months later, and finally four years later. Risky
alcohol use, social norms perceptions, academic achievement, and misconduct all were assessed.
Latent growth curve modeling revealed that social norms perceptions before entering college
were related significantly to baseline levels of alcohol use. Both initial levels of alcohol use and
changes in alcohol use predicted later social norms perceptions, confirming recent research that
has suggested reciprocal influence effects. Analyses showed that alcohol use prior to college is a
predictor of academic achievement, but change in alcohol use is not. Changes in alcohol use
were not associated with intial social norms perceptions and did not predict academic
achievement or misconduct; explanations and model improvements are discussed. Findings
underscore the importance of the transition period between high school and college and highlight
the reciprocal relationship between alcohol use and social norms perceptions.

description: The general relativistic Poynting-Robertson (PR) effect is a very important dissipative phenomenon occurring in high-energy astrophysics.

The radiation field is considered as constituted by photons emitted from a rigidly rotating spherical source around the compact object. Such dynamical system admits the existence of a critical hypersurface, region where the gravitational and radiation forces balance and the matter reaches it at the end of its motion. Selected test particle orbits are displayed. We show how to prove the stability of these critical hypersurfaces within the Lyapunov theory. Then, we present how to study such effect under the Lagrangian formalism, explaining how to analytically derive the Rayleigh potential for the radiation force. In conclusion, further developments and future projects are discussed.

description: In the 'Ageing Well Public Talk series' we are exploring how important it is, over our lifespan, to maintain well-balanced nutrition and hydration as well as regular physical and social activity in older age, also known as the 'Five Pillars of Ageing Well'. Ageing demonstrates most significantly when we reach a certain age, the usual benchmark being 65+, but ageing starts much sooner and the way ageing demonstrates when we are over 65 depends on decisions we have been making over our life span.The series and related materials such as ‘The Five Pillars of Ageing Well’ became the cornerstones of further engagement with the public, specifically around COVID-19 and the relating self-isolation, which are now available on the OU website and the Internet.The overall aim of these series of interventions is to facilitate a step change in user behaviour and support service provision. Self-management and becoming partner in our own health care is an important aspect of these talks. This may have a wider impact in healthcare economies, as ageing and related co-morbidities have a substantial health and economic burden footprint.I have been presenting the ‘Ageing Well’ Lecture Series in collaboration with Third Age University and Free Time University overseas and more recently with primary care practices in the UK. Currently also collaborating with Age UK MK, Public Health Northamptonshire, Carers MK, UKeMED & Cambridge Medical Academy, East of England Academic Health Science Network and the and Voluntary Health Scotland on delivering ‘Ageing Well Public Talks’.All talks last between 60-90 min, A synopsis for each talk is contained in this document.
Clement of Alexandria and Early Christian Views of Martyrdom
Creators: name: Helms, Lindsey
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Introduction
We cannot begin to understand Clement’s stance on martyrdom without first considering
the context in which he lived. The setting is late second-century Alexandria, a Roman epicenter
of trade and education situated on the northwest coast of Egypt. According to Strabo, the city
was erected in 331 BCE by Alexander the Great on the site of the Egyptian village Rhakotis.
When Alexander’s Hellenistic Empire was divided among three of his generals following his
death, Ptolemy I became the ruler of Egypt and began the Ptolemaic dynasty. During his reign,
Alexandria replaced Memphis as the capital of Egypt and prospered as an economic and
educational hub.
Since archaeological evidence from Alexandria preceding the fourth century CE is
scarce, much of our insight about Christianity in second- and third-century Alexandria is derived
from textual evidence. One of the largest contributors of this evidence is Eusebius, an author
whose validity is often called into question due to his failure to witness firsthand many of the
events he describes, the frequency with which he stakes claims that have no support from other
sources, and the possibility that he falsified his records in order to assert his own agenda. There
is evidence that Eusebius’ accounts are blemished by a variety of fallacies; for example, his
Church History is peppered with anachronisms and postulations that we have good reason to
doubt.
Be that as it may, we would have little to no knowledge of Alexandrian Christianity if it
were not for the information we are able to glean from Eusebius’ documentation. If held to the
same high standards that scholars criticize Eusebius for failing to meet, many sources would
likely be deemed unreliable and we would be forced to discard multitudes of crucial documents
that constitute the very foundation upon which our understanding of history is built. Therefore, I
will treat Eusebius as a source from which some knowledge about Christians in second- and
third-century Alexandria can be gathered.

description: Human-robot interaction relies on a noise-robust audio processing module capable of estimating target speech from audio recordings impacted by environmental noise, as well as self-induced noise, so-called ego-noise. While external ambient noise sources vary from environment to environment, ego-noise is mainly caused by the internal motors and joints of a robot. Ego-noise and environmental noise reduction are often decoupled, i.e., ego-noise reduction is performed without considering environmental noise. Recently, a variational autoencoder (VAE)-based speech model has been combined with a fully adaptive non-negative matrix factorization (NMF) noise model to recover clean speech under different environmental noise disturbances. However, its enhancement performance is limited in adverse acoustic scenarios involving, e.g. ego-noise. In this paper, we propose a multichannel partially adaptive scheme to jointly model ego-noise and environmental noise utilizing the VAE-NMF framework, where we take advantage of spatially and spectrally structured characteristics of ego-noise by pre-training the ego-noise model, while retaining the ability to adapt to unknown environmental noise. Experimental results show that our proposed approach outperforms the methods based on a completely fixed scheme and a fully adaptive scheme when ego-noise and environmental noise are present simultaneously.

TALEN-generated Xenopus kcp mutants show malformation of the epicardium
Creators: name: Williams, Clara
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: The epicardium, the outermost layer of the heart, is a pluripotent precursor structure that contributes cells to many non-muscle structures within the heart during development.  This study seeks to investigate the role of kielin/chordin-like protein (kcp) in the development of the epicardium. Kcp is expressed in the epicardium, and is known to act as an enhancer of bone morphogenetic protein (BMP) signaling in other organ systems. BMP is also a vital pathway in heart development, where it has been shown to direct morphogenesis, and play a role in cell migration and differentiation. However, the role kcp has in regulating BMP in the heart has not previously been characterized. We performed genome editing using Transcription Activator-Like Effector Nucleases (TALENs) to create compound heterozygous kcp mutants in Xenopus to characterize the epicardial phenotype of these mutants. We found that tbx18-marked cells failed to localize to the epicardium as seen in the control. This supports the conclusion that kcp is necessary for the correct development of the epicardium, which opens the way for further research to describe the exact nature and causes of this defect. Because the early development of the heart, and of the epicardium in particular, is highly conserved among vertebrates, these findings likely translate well in describing the role of kcp in human epicardial development.
Comprehensive molecular characterization of surgical vs. dietary weight loss: impact on mammary tumor burden
Creators: name: Doerstling, Steven S.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Background: Obesity is a widespread health concern and established risk factor for
basal-like breast cancer. However, studies are conflicted on the benefits of weight loss
relevant to breast cancer prevention. Recent studies suggest that certain methods of
robust weight loss with long-term maintenance, such as bariatric surgery, might in fact
be able to reverse obesity-associated breast cancer risk.
Hypothesis: We hypothesize that weight loss by sleeve gastrectomy will generate
sufficient metabolic normalization to reverse obesity-driven mammary tumor burden
more effectively than weight loss by diet alone.
Methods: Mice were fed a low-fat control (CON) or high-fat diet-induced obesity (DIO)
regimen for 15 weeks to model chronic obesity. DIO mice were randomized to continue
on a high-fat diet (Obese) or undergo weight loss by either sleeve gastrectomy (~70%
excision of the stomach) in combination with switching to a low-fat diet or by switching
to a low-fat diet alone, resulting in formerly obese (FOB)-Surg and FOB-Diet mice,
respectively. Additionally, a subset of normal weight (NW) Control mice (Con, n=25)
was maintained on a low-fat diet throughout the study. NW Control, FOB-Diet, and
Obese mice underwent a sham procedure to control for the insult of surgery. FOB-Surg
and FOB-Diet mice did not lose a significantly different amount of weight and body fat;
both groups had significantly lower weight and percent body fat than Obese mice. Eight
weeks after surgical procedures and diet switches, all mice on study were orthotopically
injected with E0771 mammary tumor cells, which model BLBC.
Results: At the end of study, ex vivo tumor volume in FOB-Surg mice was not
significantly different from NW Control mice and significantly different from Obese mice.
However, tumor volume in FOB-Diet mice was significantly different from NW Control
mice and not significantly different from Obese mice. In addition, FOB-Surg mice had
levels of serum tumor necrosis factor-alpha (TNF-a), insulin, and mammary adipocyte
size that were not significantly different from NW Control mice and significantly different
from FOB-Diet and Obese mice. Lastly, pathway analysis of mammary tissue gene
expression revealed redundant upregulation of genes in extracellular matrix remodeling
and growth factor signaling in Obese vs. FOB-Surg and FOB-Diet vs. FOB-Surg mice.
Conclusions: Our results demonstrate that surgical weight loss imparted a plurality of
metabolic advantages, functional genomic changes, and successful reversal of obesity-associated
mammary tumor burden that were not similarly achieved by dietary weight
loss.
