Distributions Of Sharks Across A Continental Shelf In The Northern Gulf Of Mexico, J. Marcus Drymon, Sean P. Powers, John Dindo, Brian Dzwonkowski, Terry A. Henwood Dec 2010

Distributions Of Sharks Across A Continental Shelf In The Northern Gulf Of Mexico, J. Marcus Drymon, Sean P. Powers, John Dindo, Brian Dzwonkowski, Terry A. Henwood

University Faculty and Staff Publications

Declines in shark populations have sparked researchers and fishery managers to investigate more prudent approaches to the conservation of these fish. As managers strive to improve data collection for stock assessment, fisheries-independent surveys have expanded to include data-deficient areas such as coastal regions. To that end, a catch series from a nearshore survey off Alabama was combined with data from a concurrent offshore survey with identical methodology to examine the depth use of sharks across the continental shelf (2–366 m). The combined data set contained 22 species of sharks collected from 1995 to 2008: 21 species in the offshore data …

An Assessment Of The Use Of Chimpanzees In Hepatitis C Research Past, Present And Future: 2. Alternative Replacement Methods, Jarrod Bailey Dec 2010

An Assessment Of The Use Of Chimpanzees In Hepatitis C Research Past, Present And Future: 2. Alternative Replacement Methods, Jarrod Bailey

Experimentation Collection

The use of chimpanzees in hepatitis C virus (HCV) research was examined in the report associated with this paper (1: Validity of the Chimpanzee Model), in which it was concluded that claims of past necessity of chimpanzee use were exaggerated, and that claims of current and future indispensability were unjustifiable. Furthermore, given the serious scientific and ethical issues surrounding chimpanzee experimentation, it was proposed that it must now be considered redundant — particularly in light of the demonstrable contribution of alternative methods to past and current scientific progress, and the future promise that these methods hold. This paper builds on …

An Assessment Of The Use Of Chimpanzees In Hepatitis C Research Past, Present And Future: 1. Validity Of The Chimpanzee Model, Jarrod Bailey

Experimentation Collection

The USA is the only significant user of chimpanzees in biomedical research in the world, since many countries have banned or limited the practice due to substantial ethical, economic and scientific concerns. Advocates of chimpanzee use cite hepatitis C research as a major reason for its necessity and continuation, in spite of supporting evidence that is scant and often anecdotal. This paper examines the scientific and ethical issues surrounding chimpanzee hepatitis C research, and concludes that claims of the necessity of chimpanzees in historical and future hepatitis C research are exaggerated and unjustifiable, respectively. The chimpanzee model has several major …

Environment and Nature Conservation Collection

Although managers safeguard protected areas for migratory species, little consideration has been given to how migratory species might benefit parks. Additionally, whereas land‐sea connections are considered in management of protected areas, most effort has focused on reducing negative “downstream” processes. Here, we offer a proposal to promote positive “upstream” processes by safeguarding the seasonal pulse of marine nutrients imported into freshwater and riparian ecosystems by spawning migrations of Pacific salmon. Currently, high rates of fishing limit this important contribution to species and processes that terrestrial parks were designed to protect. Accordingly, we propose limiting exploitation in areas and periods through …

Cloning Of A Chlamydomonas Reinhardtii Marker Into A Rna Interference Construct To Test Whether The Photoreceptor Chlamyrhodopsin Is Involved In Circadian Clock Resetting, Shravya Reddy Maddi Dec 2010

Cloning Of A Chlamydomonas Reinhardtii Marker Into A Rna Interference Construct To Test Whether The Photoreceptor Chlamyrhodopsin Is Involved In Circadian Clock Resetting, Shravya Reddy Maddi

Masters Theses & Specialist Projects

Chlamydomonas reinhardtii, a unicellular eukaryotic green alga, serves as a model organism to study the circadian clock in plants and animals. Rhodopsins are blue/green-light photoreceptors also found in C. reinhardtii. Chlamyrhodopsin (COP), the most abundant eyespot protein, was reported to have no role in the phototactic and photophobic responses in C. reinhardtii. Its function is yet unknown.
In the present study, we hypothesized that the function of COP is to mediate entrainment of the circadian clock by light. In order to test this hypothesis, a C. reinhardtii selection marker conferring resistance to the antibiotic paromomycin was cloned …

The Scavenging Behaviour Of The Australian Raven (Corvus Coronoides): Patterns And Influencing Factors, R. Christopher O'Brien, Alexande Larcombe, Jan Meyer, Shari L. Forbes, Ian Dadour Dec 2010

The Scavenging Behaviour Of The Australian Raven (Corvus Coronoides): Patterns And Influencing Factors, R. Christopher O'Brien, Alexande Larcombe, Jan Meyer, Shari L. Forbes, Ian Dadour

Forensic Science Publications

The Australian Raven (Corvus coronoides) is a widespread, abundant corvid which is often considered a pest species, due to the thought that it predates on livestock, ruin crops, and is often seen feeding on refuse, in both urban and rural areas. The species is known to feed on a range of material from seeds in ploughed fields to human refuse and decomposing organic material. A large proportion of its diet consists of carrion, and as such, the Australian Raven is an effective detrivorous species capable of removing and consuming dead and decomposing carcasses. This research examined the scavenging …

[Accepted Article Manuscript Version (Postprint)] Pex5 Mutants That Differentially Disrupt Pts1 And Pts2 Peroxisomal Matrix Protein Import In Arabidopsis, Bibi Khan, Bethany Zolman Dec 2010

[Accepted Article Manuscript Version (Postprint)] Pex5 Mutants That Differentially Disrupt Pts1 And Pts2 Peroxisomal Matrix Protein Import In Arabidopsis, Bibi Khan, Bethany Zolman

Biology Department Faculty Works

PEX5 and PEX7 are receptors required for the import of peroxisome-bound proteins containing one of two peroxisomal targeting signals (PTS1 or PTS2). To better understand the role of PEX5 in plant peroxisomal import, we characterized the Arabidopsis (Arabidopsis thaliana) pex5-10 mutant, which has a T-DNA insertion in exon 5 of the PEX5 gene. Sequencing results revealed that exon 5, along with the T-DNA, is removed in this mutant, resulting in a truncated pex5 protein. The pex5-10 mutant has germination defects and is completely dependent on exogenous Suc for early seedling establishment, based on poor utilization of seed-storage fatty acids. This …

Andes Virus Regulation Of Cellular Micrornas Contributes To Hantavirus-Induced Endothelial Cell Permeability, Timothy Pepini Dec 2010

Andes Virus Regulation Of Cellular Micrornas Contributes To Hantavirus-Induced Endothelial Cell Permeability, Timothy Pepini

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Hantaviruses infect human endothelial cells (ECs) and cause two diseases marked by vascular permeability defects: hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). Vascular permeability occurs in the absence of EC lysis suggesting that hantaviruses alter normal EC fluid barrier functions. Hantavirus-infected endothelial cells are hyper-responsive to vascular endothelial growth factor (VEGF) which directs changes in EC adherens junctions and induces paracellular permeability. However, VEGF-directed responses are regulated by cellular microRNAs (miRNAs). The hantavirus nucleocapsid (N) protein binds cellular and viral RNA and reportedly co-localizes with P-bodies where miRNAs mature. These findings suggest that hantaviruses may modify …

Joint Application Of Concentration And Isotope Ratios To Investigate The Global Atmospheric Carbon Monoxide Budget: An Inverse Modeling Approach, Key Hong Park Dec 2010

Joint Application Of Concentration And Isotope Ratios To Investigate The Global Atmospheric Carbon Monoxide Budget: An Inverse Modeling Approach, Key Hong Park

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Since carbon monoxide is one of the major sinks of hydroxyl radicals, it has been used as a proxy of hydroxyl radicals, which largely control the oxidizing capacity of the atmosphere. Thus, CO-related chemistry directly or indirectly affects the abundance of other atmospheric trace gases including methane, halocarbons and tropospheric ozone. Carbon monoxide has also been shown its usefulness as a tracer of transport of pollution and fire emissions and as an additional constraint for CO2 fluxes. Variations in the global CO cycle are closely related to the change of total source strengths. Previously, to estimate the global CO …

Shear-Induced Platelet Sensitization And The Development Of An Activation Model, Jawaad Sheriff Dec 2010

Shear-Induced Platelet Sensitization And The Development Of An Activation Model, Jawaad Sheriff

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Increased shear stresses are a hallmark of flow conditions in blood recirculating devices, and patients implanted with such devices require lifelong anticoagulation to counteract the high risk of thromboembolism. Despite this limitation, manufacturers only test for hemolysis in order to optimize device design. This is primarily due to the paucity of data regarding platelet damage, a major precursor of thromboembolism. Several studies have shown that platelets exposed to constant shear stress for a specified duration become activated. However, post high-shear stress activation behavior of platelets, which is critical to understanding increased thrombotic risk associated with blood recirculating devices, is poorly …

Transcriptional Regulation Of Seprase In Melanoma By The Canonical Transforming Growth Factor- (Tgf- ) Signaling Pathway, Shaun Tulley

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The tumor invasive phenotype driven by seprase expression/activity has been widely examined in an array of malignant tumor cell types, however very little is known about the regulatory mechanisms governing this critical protease. Human seprase (also named fibroblast activation protein-alpha (FAPΑ); antiplasmin-cleaving enzyme (APCE); dipeptidyl prolyl peptidase 5 (DPP5) is a 170 kDa homodimeric glycoprotein consisting of two 97 kDa subunits. Seprase is expressed at high levels by tumor cells and stromal fibroblasts in a variety of invasive carcinomas, but is essentially absent or undetectable in normal tissues except during active tissue remodeling in embryogenesis, and in the early stages …

Reading Into Race: Unsettled Reading And The Performance Of"Race", Julie Burton Swift Dec 2010

Reading Into Race: Unsettled Reading And The Performance Of"Race", Julie Burton Swift

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Reading, race, and the primary productive link between the two--performativity--are the subject of this dissertation. By reading the formative discourse of phrenology and Ethnology, as well as nineteenth-century textbooks which teach reading, I suggest a context in which reading operates as an expressive framework for the problematics of race. In considering selected works of Edgar Allan Poe, Frederick Douglass, Harriet Jacobs, and Herman Melville, I examine the uses to which reading is put, not only to elaborate, but to perform race. By looking at unsettled reading--breakdowns of reading, failures to read, readings that prove unaccountable to the text--I emphasize the …

Domain Formation In Asymmetric Model Membranes, Hui-Ting Cheng Dec 2010

Domain Formation In Asymmetric Model Membranes, Hui-Ting Cheng

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The plasma membrane of eukaryotic cells contains a lipid bilayer which acts as a physical barrier and is the site for many cellular signaling events. The lipid molecules in the plasma membrane are non-randomly distributed within the bilayer. Both their lateral organization (lipid domains) and transverse distribution (lipid asymmetry) are important in membrane function. Since the function and structure of the plasma membrane are difficult to study due to its complex and dynamic nature, a good model membrane is needed. However, commonly used procedures for liposome preparation cannot truly mimic plasma membranes because they do not provide control over lipid …

As a clean energy source, hydrogen is an attractive alternative. Among all the challenges that hydrogen economy has, it is particularly important to develop new ways to generate hydrogen without hydrocarbons. In search of cheap and robust material, we are learning from nature.Hydrogenase enzymes, which occur in a wide variety of microorganisms, catalyze the oxidization or production of molecular hydrogen (2H+ + 2e = H2,). In the case of [NiFe]-hydrogenase enzymes, the Ni is coordinated as a [Ni-(S-Cys)4] center which undergoes a series of redox changes during the catalytic processes. This work is focusing on the synthesis of model compounds …

A Quantitative Analysis Of Racial/Ethnic Disparities In Health Care Usage: The Roles Of Perceptions Of Care & Expected Longevity, Jeffrey Alfred Jones Dec 2010

A Quantitative Analysis Of Racial/Ethnic Disparities In Health Care Usage: The Roles Of Perceptions Of Care & Expected Longevity, Jeffrey Alfred Jones

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Countless studies have documented the existence of disparities byrace and ethnicity in the health care system in the United States.However, not many have sought to explicitly quantify the relativeimportance of each of the proposed determining factors. Thisdissertation thus sought to identify the major causes of disparitiesin health care usage by employing an adaptation of theBlinder/Oaxaca decomposition method originally used in theliterature on wage differentials.Specifically, this study sought to investigate the roles that racialdifferences in patients' perceptions of care and expected longevity(as they relate to expected gains) might play in the observeddisparities in usage. Perceptions of care measures (trust andfear/dislike) were …

Links Between Conservation/Development Projects And International Conventions And Programs : The Southeastern Rainforest Of Madagascar., Benedicte Leclercq

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Integrated Conservation and Development Projects (ICDPs) emerged in the 1980s and 1990s, to reconcile the need to protect threatened natural areas and, at the same time, to foster human development. Increasingly, around the world, natural resources were being rapidly depleted. In some cases local communities were held responsible for over-exploiting these resources, even when for their subsistence. The present research was based on an intensive case study of an ICDP developed within the framework of the UNESCO World Heritage Convention and implemented around Midongy-Befotaka National Park, in the Southeastern Humid Forests of Madagascar. The main activities involved were linked not …

Characterization Of Antimicrobial Activity Present In The Cuticle Of American Lobster, Homarus Americanus, Margaret Anne Mars

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

American lobster is an ecologically and socioeconomically important species. In recent years the species has been affected by disease and the catch in Southern New England has fallen dramatically. In order to fully understand how and why diseases affect lobster populations, it is imperative to fully understand lobster defense mechanisms. The cuticle, previously believed to act only as a physical barrier, has recently been shown to contain antimicrobial activity. This thesis focused on characterizing this activity and attempted to identify the molecules responsible. A sterile shell extract prepared from a pool of lobster shells was active against Vibrio parahaemolyticus, Vibrio …

The Identification Of A Novel Binding Partner For Phospholipase Cβ1, Translin-¶Ðassociated Factor X: A Link To ¶Ÿrna Interference, Omozuanvbo Reginald Aisiku Dec 2010

The Identification Of A Novel Binding Partner For Phospholipase Cβ1, Translin-¶Ðassociated Factor X: A Link To ¶Ÿrna Interference, Omozuanvbo Reginald Aisiku

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Mammalian inositol-specific phospholipase Cβ1 (PLCβ1) is activated by Gαq subunits on the plasma membrane where it catalyzes hydrolysis of the minor membrane phosphatidylinositol 4,5 bisphosphate. While PLCβ1 localizes primarily to the plasma membrane it also exists in other compartments of the cell. It is not currently known what function PLCβ1 has in the cytosol and nucleus nor is it known what factors localize PLCβ1 to these compartments. In this study, we have identified a novel binding partner, translin-associated factor X (TRAX). Our experiments show that both proteins interact in solution and in cells. While TRAX exerts little effect on the …

Fisheries-Dependent Indicators Of Climate Change In Western Australia Wamsi:Sub-Project 4.2.3, Nick Caputi, Alan Pearce Dec 2010

Fisheries-Dependent Indicators Of Climate Change In Western Australia Wamsi:Sub-Project 4.2.3, Nick Caputi, Alan Pearce

Fisheries Research Reports

The use of fishery-dependent data may be a cost-effective way of assessing whether there have been any changes in the distribution and relative abundance of species. Such indicators are part of an ongoing data gathering system and the costs are relatively low compared to those of a fishery-independent field program. Fishery-dependent data may therefore be obtained at a higher frequency and allow detection of changes faster than would be possible from the results from the direct sampling of specific sites within entire ecosystems.

Correlates Of Inter-Generational Transmission Of Intimate Partner Violence, Nivin A. Qudeimat-Tercero Dec 2010

Correlates Of Inter-Generational Transmission Of Intimate Partner Violence, Nivin A. Qudeimat-Tercero

Regis University Student Publications (comprehensive collection)

Intimate partner violence is a prevalent phenomenon plaguing society, with its negative effects being propagated from one generation to the next. The author hypothesized that there exists a qualitative correlation between male children who witnessed adult males perpetrate violence against females in childhood and subsequent adult onset perpetration of violence against women. After conducting a meta-analysis of 44 peer-reviewed articles, the author found that: (a) children who witnessed interparental IPV manifested increased disturbed behaviors as well as cognitive and emotional impairment corresponding to the severity and frequency of the episodes witnessed; and (b) men who witnessed parental IPV were more …
