Shellfish Tissue Monitoring In Piscataqua Region Estuaries 2012, Matthew A. Wood, Philip R. Trowbridge

PREP Reports & Publications

Originally conducted by a committee of Canadian and US governments and university scientists, Gulfwatch examined the effects of decades of development and industrialization on the water quality of the Gulf of Maine as it relates to human health primarily through assessing contaminant exposure of marine organisms from 1993 to 2010. The NH Gulfwatch Program continues these efforts by collecting blue mussels at two sites in the Great Bay Estuary and one in the Hampron-Seabrook Estuary, and analyzes the organisms’ tissue for potentially harmful levels and concentrations of toxins including heavy metals, chlorinated pesticides, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons …

Goats Favour Personal Over Social Information In An Experimental Foraging Task, Luigi Baciadonna, Alan G. Mcelligott, Elodie F. Briefer

Ethology Collection

Animals can use their environments more efficiently by selecting particular sources of information (personal or social), according to specific situations. Group-living animals may benefit from gaining information based on the behaviour of other individuals. Indeed, social information is assumed to be faster and less costly to use than personal information, thus increasing foraging efficiency. However, when food sources change seasonally or are randomly distributed, individual information may become more reliable than social information. The aim of this study was to test the use of conflicting personal versus social information in goats (Capra hircus), in a foraging task.We found that goats …

Scavenger Receptor Class B Type I Regulates Cellular Cholesterol Metabolism And Cell Signaling Associated With Breast Cancer Development., Christiane Danilo, Jorge L Gutierrez-Pajares, Maria Antonietta Mainieri, Isabelle Mercier, Michael P. Lisanti, Philippe G. Frank

Department of Stem Cell Biology and Regenerative Medicine Faculty Papers & Presentations

INTRODUCTION: Previous studies have identified cholesterol as an important regulator of breast cancer development. High-density lipoprotein (HDL) and its cellular receptor, scavenger receptor class B type I (SR-BI) have both been implicated in the regulation of cellular cholesterol homeostasis, but their functions in cancer remain to be established.

METHODS: In the present study, we have examined the role of HDL and SR-BI in the regulation of cellular signaling pathways in breast cancer cell lines and in the development of tumor in a mouse xenograft model.

RESULTS: Our data show that HDL is capable of stimulating migration and can activate signal …

A Novel Subnetwork Alignment Approach Predicts New Components Of The Cell Cycle Regulatory Apparatus In Plasmodium Falciparum, Hong Cai, Changjin Hong, Timothy G. Lilburn, Armando L. Rodriguez, Sheng Chen, Jianying Gu, Rui Kuang, Yufeng Wang

Publications and Research

Background According to the World Health organization, half the world's population is at risk of contracting malaria. They estimated that in 2010 there were 219 million cases of malaria, resulting in 660,000 deaths and an enormous economic burden on the countries where malaria is endemic. The adoption of various high-throughput genomics-based techniques by malaria researchers has meant that new avenues to the study of this disease are being explored and new targets for controlling the disease are being developed. Here, we apply a novel neighborhood subnetwork alignment approach to identify the interacting elements that help regulate the cell cycle of …

Recent global warming is acting across marine, freshwater, and terrestrial ecosystems to favor species adapted to warmer conditions and/or reduce the abundance of cold-adapted organisms (i.e., “thermophilization” of communities). Lack of community responses to increased temperature, however, has also been reported for several taxa and regions, suggesting that “climatic lags” may be frequent. Here we show that microclimatic effects brought about by forest canopy closure can buffer biotic responses to macroclimate warming, thus explaining an apparent climatic lag. Using data from 1,409 vegetation plots in European and North American temperate forests, each surveyed at least twice over an interval of …

Cannabinoid 2 (Cb2) Receptor Gene Promoter And Unique Rna Transcripts In B Cells And Methods Of Use, Thomas W. Klein, Tracy Sherwood, Liang Nong, Cathy Newton

USF Patents

Cannabinoid receptor 2 (CB2) is expressed in B lymphocytes and is involved in immune regulation. Mouse splenic B cells express three CB2 transcripts utilizing two different first exons. Human peripheral blood B cells express one CB2 transcript utilizing one first exon. Alignment of sequenced RACE products to either the mouse or human genome reveals that isolated transcripts contain previously unidentified transcriptional start sites (TSS). B cells from mouse and human preferentially express one transcript, exon 1a in mouse and exon 1 in human. Multiple CB2 TSSs are utilized in mouse splenic B cells and one TSS in human peripheral blood …

Learning To Work With Clients : A Quantitative Study On Educational Pathways For Social Workers Working With Psychotropic Medication, Katherine S. Preston

Theses, Dissertations, and Projects

The current study explored how clinical social workers working with patients who are prescribed psychotropic medication went about developing the knowledge and skills to work with the population. The study identified training activities that contribute to the development of practice skills, and examined the relationship between these activities and self-rated practice competency levels. A snowball sample of 28 clinical social workers whose scope of practice included collaborating on the care of patients who are prescribed psychotropic medications were recruited. Participants completed a brief, anonymous, online questionnaire that was developed for the current study, and informed by the work of Bentley, …

Melanoma Biomolecules: Independently Identified But Functionally Intertwined, Danielle E. Dye, Sandra Medic, Mel R. Ziman Dr, Deirdre R. Coombe

Research outputs 2013

The majority of patients diagnosed with melanoma present with thin lesions and generally these patients have a good prognosis. However, 5% of patients with early melanoma (thick) will have recurrence and die within 10 years, despite no evidence of local or metastatic spread at the time of diagnosis. Thus, there is a need for additional prognostic markers to help identify those patients that may be at risk of recurrent disease. Many studies and several meta-analyses have compared gene and protein expression in melanocytes, naevi, primary, and metastatic melanoma in an attempt to find informative prognostic markers for these patients. However, …

An Exploration Of The Effects Of Stigma On The Experiences Of Foster Care Alumni, Anais J. Penninck

Theses, Dissertations, and Projects

The purpose of this qualitative study was to explore the experiences of stigma on foster care alumni. Participants were asked about their experiences in foster care related to stigma and how this may have affected their relationships and personal development. They were also prompted to share any other information the researcher may have missed. Six men were interviewed for this study between the ages of 19 and 37. The interviews provided rich information about how they interpreted the stigma and what short and long-term effects were results of this stigma. Additionally, the majority of participants who identified stigma described it …

Quantifying Mutational Impacts On Intrinsic Dna Flexibility In Prokaryotic Genomes, Mohammed Alawad

Theses

The existence of synonymous codon biases across all taxonomic groups is a long standing problem in biology. While codon bias seems to be adequately explained by the maintenance of translation efficiency and accuracy in some organisms, there is still no adequate explanation of why codon biases universally track the intergenic gc content, as these regions of the genome would not be under selection pressures affecting translation. One part of the story may come from the triplet nature of codon in which each third position defines the minor groove width and thus affects the basic structure of the DNA by altering …

Consistent Surgeon Evaluations Of Three-Dimensional Rendering Of Pet/Ct Scans Of The Abdomen Of A Patient With A Ductal Pancreatic Mass., Matthew E Wampole, John C Kairys, Edith P Mitchell, Martha L Ankeny, Mathew L Thakur, Eric Wickstrom

Department of Biochemistry and Molecular Biology Faculty Papers

Two-dimensional (2D) positron emission tomography (PET) and computed tomography (CT) are used for diagnosis and evaluation of cancer patients, requiring surgeons to look through multiple planar images to comprehend the tumor and surrounding tissues. We hypothesized that experienced surgeons would consistently evaluate three-dimensional (3D) presentation of CT images overlaid with PET images when preparing for a procedure. We recruited six Jefferson surgeons to evaluate the accuracy, usefulness, and applicability of 3D renderings of the organs surrounding a malignant pancreas prior to surgery. PET/CT and contrast-enhanced CT abdominal scans of a patient with a ductal pancreatic mass were segmented into 3D …

Urbanism And North American Funerary Practices, Rebecca Marrall

PSU McNair Scholars Online Journal

Urbanism is a way of life for those who reside in a densely inhabited area with a heterogeneous human population. The diversity of cultures, worldviews and practices found in urban areas combine in a form of cultural mixing. The urban amalgamation of cultures raises the question of how urban dwellers process their dead. Indeed, does urbanism influence regional death rituals and funerary practices? Other elements such as urban zoning laws, funerary technology or land scarcity add further dimensions to the original question. In short, do urban funerary practices and death rituals differ precisely because they are urban? My research examines …

Food Web Impacts Of The Invasive New Zealand Mudsnail In An Estuarine System, Amanda L. Kelley

PSU McNair Scholars Online Journal

Non-indigenous species (hereafter NIS) have long been recognized as adversely affecting habitats they invade. While many of their documented ecological impacts have been to specific species, namely prey, they may impact whole food webs. Both vertebrate and invertebrate NIS have been present in the Columbia River since the mid 1800’s. The New Zealand mudsnail, (Potamopyrgus antipodarum, hereafter NZMS) was first reported in the Columbia River Estuary in 1995. This typically freshwater NIS invaded Youngs Bay, a shallow embayment within the Columbia River estuary system, and has proliferated within this benthic community. To date, there have been no inquiries into the …

Oviposition Site Choice In A Neotropical Treefrog, Dendropsophus Ebraccatus, Julie Worley

PSU McNair Scholars Online Journal

An organism’s fitness is determined by its ability to produce viable offspring. For animals that lack post-hatching parental care, assessing and discriminating between oviposition sites may increase offspring survival. The Neotropical treefrog, Dendropsophus ebraccatus, is the only vertebrate known to be able to lay eggs both aquatically and terrestrially, and can do so in a given night. Laying eggs in water can increase hypoxia and aquatic predation, whereas desiccation and terrestrial predation increase with oviposition on land. Dendropsophus ebraccatus therefore provides a unique opportunity to measure adult reproductive choices in response to opposing costs associated with aquatic versus terrestrial reproduction. …

The Effect Of Road Culverts On The Benthic Macroinvertebrate Community In Wadeable Lotic Ecosystems, Travis Peterson

PSU McNair Scholars Online Journal

Roads and lotic ecosystems intersect as their paths unfold across the landscape. At their intersections lotic ecosystems are often routed underneath a road through a culvert. Road culverts allow the transportation system and lotic ecosystem to coexist, but their presence can introduce physical stress on the local ecology. The purpose of this study was to investigate the effects of road culverts on the benthic macroinvertebrate community. I collected physical habitat, water quality, and benthic macroinvertebrate data from three sample units near the culverted sections of two lotic ecosystems. Sample units were positioned in a longitudinal configuration with a reference sample …
