Thalassiosira Spp. Community Composition Shifts In Response To Chemical And Physical Forcing In The Northeast Pacific Ocean, P. Dreux Chappell, Leann P. Whitney, Traci L. Haddock, Susanne Menden-Deuer, Eric G. Roy, Mark L. Wells, Bethany D. Jenkins

Cell and Molecular Biology Faculty Publications

Diatoms are genetically diverse unicellular photosynthetic eukaryotes that are key primary producers in the ocean. Many of the over 100 extant diatom species in the cosmopolitan genus Thalassiosira are difficult to distinguish in mixed populations using light microscopy. Here, we examine shifts in Thalassiosira spp. composition along a coastal to open ocean transect that encountered a 3-month-old Haida eddy in the northeast Pacific Ocean. To quantify shifts in Thalassiosira species composition, we developed a targeted automated ribosomal intergenic spacer analysis (ARISA) method to identify Thalassiosira spp. in environmental samples. As many specific fragment lengths are indicative of individual Thalassiosira spp., …

Rov-Based Tracking Of A Shallow Water Nocturnal Squid, Samuel Yim, Christopher M. Clark, Timothy Peters, Vladimir Prodanov, Pat Fidopiastis

Biological Sciences

This paper describes the use of a Remotely Operated Vehicle (ROV) equipped with a monocular vision system to find and track the squid Euprymna scolopes, so that motion behaviors of the squid could be characterized through the use of off-line image processing and state estimation. The ROV was deployed for several nights at several nearshore locations off Oahu, resulting in 10 hours of squid footage. Using blob-tracking image processing techniques and a Particle Filter state estimator, the squid can be detected and tracked. The position, velocity, and acceleration of the squid relative to the stationary ROV can be determined. Experiment …

Genomic Insights Into Triple-Negative And Her2-Positive Breast Cancers Using Isogenic Model Systems, Prakriti Mudvari, Kazufumi Ohshiro, Vasudha S. Nair, Anelia Horvath, Rakesh Kumar

Biochemistry and Molecular Medicine Faculty Publications

Introduction

In general, genomic signatures of breast cancer subtypes have little or no overlap owing to the heterogeneous genetic backgrounds of study samples. Thus, obtaining a reliable signature in the context of isogenic nature of the cells has been challenging and the precise contribution of isogenic triple negative breast cancer (TNBC) versus non-TNBC remains poorly defined.

Methods

We established isogenic stable cell lines representing TNBC and Human Epidermal Growth Factor Receptor 2 positive (HER2+) breast cancers by introducing HER2 in TNBC cell lines MDA-MB-231 and MDA-MB-468. We examined protein level expression and functionality of the transfected receptor by treatment with …

Role Of Endothelial To Mesenchymal Transition In The Pathogenesis Of The Vascular Alterations In Systemic Sclerosis., Sergio A Jimenez

Scleroderma Center Faculty Papers

The pathogenesis of Systemic Sclerosis (SSc) is extremely complex, and despite extensive studies, the exact mechanisms involved are not well understood. Numerous recent studies of early events in SSc pathogenesis have suggested that unknown etiologic factors in a genetically receptive host trigger structural and functional microvascular endothelial cell abnormalities. These alterations result in the attraction, transmigration, and accumulation of immune and inflammatory cells in the perivascular tissues, which in turn induce the phenotypic conversion of endothelial cells and quiescent fibroblasts into activated myofibroblasts, a process known as endothelial to mesenchymal transition or EndoMT. The activated myofibroblasts are the effector cells …

Sensor-Driven Hierarchical Path Planning For Unmanned Aerial Vehicles Using Canonical Tasks And Sensors, Spencer James Clark

Theses and Dissertations

Unmanned Aerial Vehicles (UAVs) are increasingly becoming economical platforms for carrying a variety of sensors. Building flight plans that place sensors properly, temporally and spatially, is difficult. The goal of sensor-driven planning is to automatically generate flight plans based on desired sensor placement and temporal constraints. We propose a simple taxonomy of UAV-enabled sensors, identify a set of generic sensor tasks, and argue that many real-world tasks can be represented by the taxonomy. We present a hierarchical sensor-driven flight planning system capable of generating 2D flights that satisfy desired sensor placement and complex timing and dependency constraints. The system makes …

The Role Of Phob In The Phosphate Signaling Pathway, Eliza H. Norcross, Dr. William R. Mccleary

Journal of Undergraduate Research

Every living cell requires a means of sensing its environment and responding appropriately. Even a single cell needs to coordinate its functions to survive. One way cells process environmental stimuli is through signal transduction pathways. Types of signaling used in bacteria include two component systems. “Two component” refers to the two parts of the system, a histidine kinase and a response regulator. The bacterium E. coli uses a two component system called the phosphate signaling pathway to sense and respond to varying levels of phosphate in the environment.

The Size Of A Melanin-Based Plumage Ornament Correlates With Glucocorticoid Receptor Concentrations In The Skin Of That Ornament, Christine R. Lattin, L. Michael Romero

Faculty Publications

© 2013 The Author(s) Published by the Royal Society. All rights reserved. Glucocorticoid hormones such as corticosterone (CORT) play crucial roles in many physiological processes. CORT's actions are primarily mediated via binding to two receptors (glucocorticoid receptors (GRs) and mineralocorticoid receptors (MRs)) in different target tissues. CORT receptors can be independently regulated from circulating hormone titres, from tissue to tissue and even within different regions of the same tissue type. Increasing evidence has shown relationships between circulating CORT and melaninbased pigmentation in skin and feathers, yet to our knowledge, there have been no studies of CORT receptors in the skin …

The hero shrew's (Scutisorex somereni) massive interlocking lumbar vertebrae represent the most extreme modification of the vertebral column known in mammals. No intermediate form of this remarkable morphology is known, nor is there any convincing theory to explain its functional significance. We document a new species in the heretofore monotypic genus Scutisorex; the new species possesses cranial and vertebral features representing intermediate character states between S. somereni and other shrews. Phylogenetic analyses of DNA sequences support a sister relationship between the new species and S. somereni. While the function of the unusual spine in Scutisorex is unknown, it gives these …

Surviving: One Family’S Experience With Cancer, Jennifer M. Denmon

The Qualitative Report

People experience trauma in many ways. Discussing the trauma in the form of illness narratives can be beneficial, not only to the patient, but for their families as well (Hydén, 1997). Illness narratives are becoming more popular in the medical field, but mostly are written from the perspective of the patient and their spouse. Little is written from the perspective of the children. In this article, my immediate family and I write our narratives detailing the experience of my father’s cancer. Major themes that emerged from our stories are disbelief, unreliable memories, wanting to forge ahead, and a stronger family. …

Green Synthesis, Processing And Characterization Of Nanostructured Metal- And Bi-Metal (Hydroxy-)Stannates, Kuo-Ting Liao

Doctoral Dissertations

Because our limited fossil fuel reserves are being depleted while worldwide energy demands are increasing, an energy crisis has emerged. To mitigate the problem, one major approach is to design and discover new energy materials with superior cost-effectiveness and functionality. Along this line, this dissertation work presents a high-throughput, low temperature and solution-based, green synthesis and processing strategy to enable various nanostructured, metal and bi-metal stannates for future energy storage and harvesting applications.

Specifically, a generic green synthesis route was developed by applying a room temperature, solution-based process for nanostructured copper and copper-zinc hydroxystannate [CuSn(OH)₆(CuHS) and Cu_{x …}

Β2 Adrenergic Receptor Fluorescent Protein Fusions Traffic To The Plasma Membrane And Retain Functionality, Jaclyn Bubnell, Patrick Pfister, Maria L. Sapar, Matthew E. Rogers, Paul Feinstein

Publications and Research

Green fluorescent protein (GFP) has proven useful for the study of protein interactions and dynamics for the last twenty years. A variety of new fluorescent proteins have been developed that expand the use of available excitation spectra. We have undertaken an analysis of seven of the most useful fluorescent proteins (XFPs), Cerulean (and mCerulean3), Teal, GFP, Venus, mCherry and TagRFP657, as fusions to the archetypal G-protein coupled receptor, the β2 adrenergic receptor (β2AR). We have characterized these β2AR::XFP fusions in respect to membrane trafficking and G-protein activation. We noticed that in the mouse neural cell line, OP 6, that membrane …

Food Insecurity Among Children In Massachusetts, Stephanie Ettinger De Cuba, Deborah A. Frank, Maya Pilgrim, Maria Buitrago, Anna Voremberg, Harris Rollinger, Denise A. Hines

New England Journal of Public Policy

This article focuses on the prevalence among Massachusetts children and families of food insecurity, inadequate access to enough nutritious food for an active and healthy life. It summarizes research findings on the association of food insecurity with less optimal children’s health and development from the prenatal period through adolescence. Food insecurity also correlates with other material hardships, such as housing and energy insecurity. Data show families’ participation in public nutrition and other assistance program is associated with decreased prevalence of food insecurity and with mitigation of its impact on children’s health and well-being. The article concludes with recommendations for policy …

Department of Veterinary Clinical Sciences Faculty Publications

Background

Herpes simplex virus 1 (HSV-1) and varicella zoster virus (VZV) cause extensive intra-ocular and neural infections in humans and are closely related to Felid herpes virus 1 (FeHV-1). We report the extent of intra-ocular replication and the extent and morphological aspects of neural replication during the acute and latent phases of FeHV-1 infection. Juvenile, SPF cats were inoculated with FeHV-1. Additional cats were used as negative controls. Cats were euthanized on days 6, 10, and 30 post-inoculation.

Results

FeHV-1 was isolated from the conjunctiva, cornea, uveal tract, retina, optic nerve, ciliary ganglion (CG), pterygopalatine ganglion (PTPG), trigeminal ganglion (TG), …

Allergic airway inflammation is attenuated by oral tolerization (oral exposure to allergen, followed by conventional sensitization and challenge with homologous antigen), which decreases airway allergen challenge-induced eosinophilic infiltration of the lungs and bone marrow eosinophilia. We examined its effects on bone marrow eosinophil and neutrophil production. Mice of wild type (BP-2, BALB/c, and C57BL/6) and mutant strains (lacking iNOS or CD95L) were given ovalbumin (OVA) or water (vehicle) orally and subsequently sensitized and challenged with OVA (OVA/OVA/OVA and H2O/OVA/OVA groups, resp.). Anti-OVA IgG and IgE, bone marrow eosinophil and neutrophil numbers, and eosinophil and neutrophil production ex vivo were evaluated. …
