Pixel-Based Absorption Correction For Dual-Tracer Fluorescence Imaging Of Receptor Binding Potential, Stephen C. Kanick, Kenneth M. Tichauer, Jason Gunn, Kimberley S. Samkoe, Brian W. Pogue

Dartmouth Scholarship

Ratiometric approaches to quantifying molecular concentrations have been used for decades in microscopy, but have rarely been exploited in vivo until recently. One dual-tracer approach can utilize an untargeted reference tracer to account for non-specific uptake of a receptor-targeted tracer, and ultimately estimate receptor binding potential quantitatively. However, interpretation of the relative dynamic distribution kinetics is confounded by differences in local tissue absorption at the wavelengths used for each tracer. This study simulated the influence of absorption on fluorescence emission intensity and depth sensitivity at typical near-infrared fluorophore wavelength bands near 700 and 800 nm in mouse skin in order …

Investigating The Role Of Micrornas In The Response To Nitrogen Deprivation In The Green Alga Chlamydomonas Reinhardtii, Adam Voshall

School of Biological Sciences: Dissertations, Theses, and Student Research

Microalgae are gaining attention as a potential feedstock for the production of biodiesel, mainly derived from triacylglycerols (TAG). In many algae, TAG synthesis increases dramatically upon certain stresses but this is often accompanied by growth retardation. Rational improvements to strain productivity are limited by the scant knowledge on algal lipid metabolism and gene regulatory mechanisms. In this context, systems-level approaches aimed at understanding and modeling metabolic and regulatory networks may enable hypothesis-driven genetic engineering strategies. The green microalga Chlamydomonas reinhardtii accumulates significant amounts of TAGs under nutrient starvation and provides a genetically tractable model for manipulating biosynthetic pathways. In order …

Enhanced Breast Cancer Therapy With Nspefs And Low Concentrations Of Gemcitabine, Shan Wu, Jinsong Guo, Wendong Wei, Jue Zhang, Jing Fang, Stephen J. Beebe

Bioelectrics Publications

Chemotherapy either before or after surgery is a common breast cancer treatment. Long-term, high dose treatments with chemotherapeutic drugs often result in undesirable side effects, frequent recurrences and resistances to therapy. The anti-cancer drug, gemcitabine (GEM) was used in combination with pulse power technology with nanosecond pulsed electric fields (nsPEFs) for treatment of human breast cancer cells in vitro. Two strategies include sensitizing mammary tumor cells with GEM before nsPEF treatment or sensitizing cells with nsPEFs before GEM treatment.Breast cancer cell lines MCF-7 and MDA-MB-231 were treated with 250 65 ns-duration pulses and electric fields of 15, 20 or 25 …

Endothelial Nitric Oxide Synthase Is Regulated By Erk Phosphorylation At Ser602, John C. Salerno, Dipak K. Ghosh, Raj Razdan, Katy A. Helms, Jonathan L. Mcmurry, Emily A. Rye, Carol A. Chrestensen

Faculty Articles

eNOS (endothelial nitric oxide synthase) contains a MAPK (mitogen-activated protein kinase)-binding site associated with a major eNOS control element. Purified ERK (extracellular-signal-regulated kinase) phosphorylates eNOS with a stoichiometry of 2–3 phosphates per eNOS monomer. Phosphorylation decreases NO synthesis and cytochrome c reductase activity. Three sites of phosphorylation were detected by MS. All sites matched the SP and TP MAPK (mitogen-activated protein kinase) phosphorylation motif. Ser602 lies at the N-terminal edge of the 42-residue eNOS AI (autoinhibitory) element. The pentabasic MAPK-binding site lies at the opposite end of the AI, and other critical regulatory features are between them. Thr46 and Ser58 …

The Kids Are All Right Online: Teen Girls' Experiences With Self-Presentation, Impression Management & Aggression On Facebook, Alison Michelle Hill

Dissertations, Theses, and Capstone Projects

Online social network participation is widespread among American adolescents. Prolific creators, consumers and curators of content, they write themselves into being (boyd, 2007) on social network sites like Facebook. Drawing on Erving Goffman's study of symbolic interaction in the form of dramaturgical perspective and The Third Person Effect, this research explores how young women ages 14-17 craft their self-presentations, engage in impression management, and experience aggression and bullying on Facebook. I propose that the majority of this age cohort craft online self-presentations that are consistent with their offline selves, yet they believe that other girls their age use their profiles …

Jean Sénac, Poet Of The Algerian Revolution, Kai G. Krienke

Dissertations, Theses, and Capstone Projects

The work presented here is an exploration of the poetry and life of Jean Sénac, and through Sénac, of the larger role of poetry in the political and social movements of the 50s, 60s, and early 70s, mainly in Algeria and America. While Sénac was part of the European community in Algeria, his position regarding French rule changed dramatically over the course of the Algerian War, (between 1954 and 1962) and upon independence, he became one the rare French to return to his adopted homeland. I will argue, sometimes polemically, that Sénac was and should be considered a properly Algerian …

Age-Related Aspects Of Mirror-Use By Bottlenose Dolphins (Tursiops Truncatus), Rachel A. Morrison

Dissertations, Theses, and Capstone Projects

Bottlenose dolphins are neuroanatomically different and evolutionarily divergent from primates yet they exhibit mirror self-recognition (MSR), a rare cognitive ability in non-human animals. This research investigated the developmental and age-related aspects of MSR in this species. During a longitudinal study, a social group of bottlenose dolphins at the National Aquarium, Baltimore, MD were exposed to a mirror and their behavioral responses were recorded to: 1) further confirm the presence of MSR in this species, 2) determine the age of emergence of MSR and 3) draw comparisons with data documenting the emergence of this ability in humans and great ape species. …

Work-Life Experiences For People With Mobility Disabilities In New York City, Jessica A. Murray

Dissertations, Theses, and Capstone Projects

Work-family (or work-life) studies aim to measure interactions between the realms of work and home. It is necessary to examine these interactions within a broad context to understand external sources of tension on the work-life dynamic, including environmental, economic, and political factors. Exploratory interviews were conducted with participants of working age with a mobility disability, and when applicable, their significant others. Questions focused on work, home and transportation environments. Using Bronfenbrenner's ecological systems theory, a model of contextual issues was constructed as the basis for an in-depth analysis of work-life issues for people with a mobility disability. Contextual research and …

Risk Assessment Of Sexually Abusive Clergy: Utility Of Sex Offender Risk Instruments With A Unique Offender Subgroup, Anthony Perillo

Dissertations, Theses, and Capstone Projects

Sex offender risk instruments provide empirically based outlooks on recidivism risk and often serve as a critical part of sex offender management. If applied to unrepresented offender groups, these instruments may offer inaccurate pictures of risk and hinder efforts to reduce sexual violence. With little research available on sexually abusive clergy prior to the abuse scandal of the early 2000s, sexually abusive clergy are one group not represented in the research used to develop risk measures. An understanding of the validity of current risk assessment practices with sexually abusive clergy is critical and timely, as changes to the handling of …

Component Trees For The Exploration Of Macromolecular Structures In Biology, Lucas Oliveira

Dissertations, Theses, and Capstone Projects

Understanding the three-dimensional structure of a macromolecular complex is essential for understanding its function. A component tree is a topological and geometric image descriptor that captures information regarding the structure of an image based on the connected components determined by different grayness thresholds. This dissertation presents a novel interactive framework for visual exploration of component trees of the density maps of macromolecular complexes, with the purpose of improved understanding of their structure. The interactive exploration of component trees together with a robust simplification methodology provide new insights in the study of macromolecular structures. An underlying mathematical theory is introduced and …

Foraging Ecology Of Shorebirds At A Stopover Site: Niche Dynamics, Aggression And Resource Use In Delaware Bay, Ivana Novcic

Dissertations, Theses, and Capstone Projects

Classical ecological theory predicts that generally similar species ought to partition resources in order to minimize competition amongst themselves. This basic idea becomes complex when one is dealing with species that migrate over thousands of miles and forage in a broad diversity of habitats and geographical locations. I studied a suite of migratory sandpipers, and asked whether they partitioned niches at a major migratory stopover in Delaware Bay. During migration, shorebirds form large, usually mixed-species flocks, which forage on marshes, mudflats, beaches or similar two-dimensional habitats where all individuals are distributed on the same horizontal plane. These habitats are often …

Oxocarbenium Ion And Alkene Metathesis Strategies For The Synthesis Of Complex Cyclohexanes, Clayton Errol Mattis

Dissertations, Theses, and Capstone Projects

Highly oxygenated cyclohexanes comprise the structures of a number of pharmacologically interesting molecules, including potently bioactive natural products and carbapyranosides. The latter, which are unnatural analogues of carbohydrates in which the ring oxygen of the parent sugar is replaced with a methylene group, have attracted interest as hydrolytically stable mimetics of their parent O-glycosides. This research reports the development of two general methodologies for the synthesis of highly oxygenated cyclohexanes: (1) Oxocarbenium Ion Cyclization (OCC) and (2) Ring Closing Metathasis (RCM).

Chapter one gives a review of the literature on the synthesis for highly oxygenated cyclohexanes.

Systematics And Evolution Of Leandra S.Str. (Melastomataceae, Miconieae), Marcelo Reginato

Dissertations, Theses, and Capstone Projects

Phylogenetic studies in the Melastomataceae have demonstrated the need of taxonomic rearrangements in the current classification. Melastomes are among the most diverse groups of plants and several cases of known artificial taxa are observed and awaiting further resolution. One example is the Leandra s.str. clade, which includes the majority of the taxa traditionally treated in the genus Leandra. Some attempts have been made to infer the relationships of Leandra s.str., but the sampling in these earlier studies was sparse and the resolution low inside the clade. The main objective here is to propose a comprehensive phylogenetic framework for this group …

Implicit Bias About Disabilities: Does It Exist For Forensic Interviewers And Could It Affect Child Credibility Decisions In Child Abuse Investigations: An Exploratory Study, Elizabeth Reiman

Dissertations, Theses, and Capstone Projects

This research project considered two questions regarding forensic interviewers: Do forensic interviewers hold implicit biases toward people with disabilities? If so, could this influence whether a forensic interviewer finds a child with a disability believable? To examine these questions, a quantitative exploratory study was conducted. Using an online survey, participants were randomly assigned to read a scenario about a child's disclosure of sexual abuse (children with and without a disability), and respond to questions about the believability of the child. Participants then completed an adapted version of the Disability Attitude Implicit Association Test (DA-IAT). The results yielded four significant findings. …

Identification And Characterization Of Protein Kinase C Substrates In Human Breast Cells, Xin Zhao

Dissertations, Theses, and Capstone Projects

Aberrations in PKC signaling can lead to the development of multiple human diseases and the most prominent association of PKC with disease has been in tumor growth and metastasis. PKC and its related pathways have been recognized as promising targets for blocking the malignancy of breast cancer cells. To better understand PKC-mediated pathway in breast cancer cells, it is important to identify the cellular substrates of PKC. The main focus of this work is to identify physiologically relevant cellular substrates of PKC in human breast cells and to characterize their roles in cancer-related phenotypes. The work to be described consists …

Optical Spectroscopy Of Xenon-Related Defects In Diamond, Yury Dziashko

Dissertations, Theses, and Capstone Projects

The work presents the results of optical studies of Xe-related defect in diamond. This defect is one of a few having narrow zero-phonon line in the near-infrared part of the photo-luminescence spectra. It appears in diamond after Xe+ ion implantation followed by thermal annealing. Given unique physical properties of diamond (hardness, optical transparency in wide spectral range, chemical inertness, high thermal conductivity, low thermal expansion coefficient) and stability of Xe-related center it can be viewed as an potential candidate for the source of single-photons, or as optically manipulated qubit, not unlike nitrogen-vacancy center. However, compared to the latter Xe-related center …

Ecological Niches, Species Distributions, And Biogeographic Processes In Rodents On Neotropical Sky Islands, Mariano Soley

Dissertations, Theses, and Capstone Projects

This dissertation focused on the methodological and theoretical improvement of correlative ecological niche models (ENMs) to better understand the processes governing species distributions and associated evolutionary divergence in rodents inhabiting mesic conditions in the Neotropics. Focusing on a widespread rodent from northern South America (Heteromys anomalus), in the first chapter I proposed and tested a methodological approach to surmount the challenge of incorporating environmental information from the margins of species geographic ranges into ENMs. In so doing, I argue how populations that exist on the borders of species' local ranges (spatial margins) can lead to exaggerated estimates of their niches …

The Influence Of An Appetitive Conditioned Stimulus On Interval Timing Behavior, Joseph Daniel Jacobs

Dissertations, Theses, and Capstone Projects

Pavlovian incentive motivation provides a theoretical framework on the basis of which experiments can be designed to examine the effects of motivational variables on timing behavior. The Pavlovian-Instrumental transfer (PIT) paradigm is a prototype for studying Pavlovian incentive motivation. The current study examined the effect of a Pavlovian appetitive conditioned stimulus (CS) on timing performance, based on the PIT paradigm. Nine pigeons were exposed to pairings of a 120-s conditioned stimulus (flashing or steady houselight) and unconditioned stimulus (food). The pigeons were then trained on the peak procedure (FI 30 s). In a subsequent testing phase, the effect of the …

The Function Of The Phospholipid Flippase Atp8a1 In Neurotransmission, Brain Development And Autistic Behavior, Daniel Joseph Kerr

Dissertations, Theses, and Capstone Projects

The function of the phospholipid flippase Atp8a1 in neurotransmission, brain development, and autistic behavior

By

Daniel J. Kerr

The plasma membrane consists of lipids and proteins. Among the integral membrane proteins are P-type ATPases, widely expressed in both prokaryotes and eukaryotes, which use ATP to translocate ions across a plasma membrane. Type IV enzymes are putative aminophospholipid translocases (APLTs) and catalyze phosphatidylserine (PS) transfer into the cytosolic leaflet of a lipid bilayer. Previously, our group showed pronounced PS externalization in Atp8a1 (-/-) mice but not wild type (WT). Subsequent behavioral testing demonstrated that these Atp8a1 (-/-) mice display significant deficiency …

A Role Of Yeast Adhesin Amyloids In Force-Dependent Adhesion And Biofilm Formation, Cho Xiao Juan Chan

Dissertations, Theses, and Capstone Projects

Candida albicans adhesins have amyloid-forming sequences (Ramsook et al. 2010, Otoo et al. 2008). Similarly, Tango and Waltz predicted that amyloid-forming sequences are also present in Saccharomyces cerevisiae flocculins, Flo1p and Flo11p. The cell surface of Flo1p- and Flo11p-expressing cells have ordered domains that are thioflavin T fluorescent and Congo red birefringent, two hallmarks of amyloids. Flo1p and Flo11p amyloids were important for activities of the flocculins including cell-to-cell adhesion, cell-to-substrate adhesion, and agar invasion. In addition, amyloid-perturbing dyes thioflavin S and Congo red inhibited aggregation, biofilm formation and agar invasion.

Force-induced formation and propagation of adhesion nanodomains in Als5p-expressing …

Dissertations, Theses, and Capstone Projects

There has been a serious deterioration of Palauan culture, language and traditional practices over the last century. To promote health and avoid this deterioration of tradition, ecological, ethnobotanical and phytochemical studies have been carried out on the plant Phaleria nisidai Kaneh. (Thymelaeaceae), "Delal a Kar", Palauan for "Mother of Medicine". This study is the first study that sets the foundations for the development of natural Palauan therapeutics, through validation of ethnomedically significant plants. Validations of these plants is done through documenting Palauan plant ethnomedical data; mapping the distribution of Palauan plants on limestone Rock Islands; and analyzing ethnopharmacological and phytochemical …

A Derivation Of The Tonal Hierarchy From Basic Perceptual Processes, David Smey

Dissertations, Theses, and Capstone Projects

In recent decades music psychologists have explained the functioning of tonal music in terms of the tonal hierarchy, a stable schema of relative structural importance that helps us interpret the events in a passage of tonal music. This idea has been most influentially disseminated by Carol Krumhansl in her 1990 monograph Cognitive Foundations of Musical Pitch. Krumhansl hypothesized that this sense of the importance or centrality of certain tones of a key is learned through exposure to tonal music, in particular by learning the relative frequency of appearance of the various pitch classes in tonal passages. The correlation of pitch-class …

The Development And Function Of The Nasopharynx And Its Role In The Evolution Of Primate Respiratory Abilities, Anthony Santino Pagano

Dissertations, Theses, and Capstone Projects

The nasopharynx is a centrally located region of the upper respiratory tract (URT) integral to several physiological functions. However, few have focused on this area within the context of human evolution. This study investigated osseous morphology, soft tissue histology, development, and evolutionary change of the nasopharynx. Multimodal analyses were performed:

Analysis 1: This study tested hypotheses on the morphological relationships of the osseous nasopharyngeal boundaries with the splanchnocranium and basicranium among dry crania representing humans and non-human primates using 3D geometric morphometrics (3D-GM). Results showed that humans, the most orthognathic group, exhibited the widest nasopharynges. Over human development, the nasopharynx …

A Feminist Inheritance? Questions Of Subjectivity And Ambivalence In Paul Mccarthy, Mike Kelley And Robert Gober, Marisa White-Hartman

Dissertations, Theses, and Capstone Projects

Feminist art of the 1970s was groundbreaking in many regards and importantly impacted specific projects by three male artists: Paul McCarthy's performance Sailor's Meat (1975), Mike Kelley's installation Half a Man (1989) and Robert Gober's 1989 installation at the Paula Cooper Gallery. Despite the general absence of feminist artists as possible influences in the critical literature on these artists, feminist sources have been hidden in plain sight in regards to these works. These artists all take up the problematic of identity formation within the domestic sphere, which was made a legitimate area of inquiry in art by numerous feminist artists …

The Interaction Between Arsenic And Struvite During Coprecipitation And Adsorption Processes, Ning Ma

Dissertations, Theses, and Capstone Projects

The formation of struvite, MgNH4PO4*6H2O (MAP), from wastes is one of the methods that can be used to recover P from wastes efficiently. However, since there are usually toxic components in the wastes, like arsenic (As), the possibility of having toxic contaminants in MAP is a big concern. So, the interaction between As and MAP during coprecipitation (CPT) and adsorption (ADS) processes were studied at pH 8-11. MAP precipitated without As at pH 8-11 was also characterized.

During CPT process, the MAP was precipitated from a MgCl2-(NH4)2HPO4-NaCl-H2O system spiked with As at an initial pH (pHi) of 8-11. The batch …

Executive Dysfunction And Reward Dysregulation: Interactions In Drug Addiction, Kristen Paula Morie

Dissertations, Theses, and Capstone Projects

Cocaine addiction is a serious public health hazard, and contributes to disastrous outcomes for individuals who suffer from it. Addiction is accompanied by an inability to control one's own behavior, and a preoccupation with cocaine at the expense of other rewarding pursuits. Previous research has suggested that difficulties with executive function and reward processing may underlie these problems, but the extent to which each contributes to addiction severity, or how these two factors may interact, remains to be elucidated. By using event related potential (ERP) measures in combination with information about self-reported anhedonia over three experiments, we set out to …
