Simultaneous Positive and Purifying Selection on Overlapping Reading Frames of the tat and vpr Genes of Simian Immunodeficiency Virus
(East Carolina University, 2001-09)Tat-specific cytotoxic T cells have previously been shown to exert positive Darwinian selection favoring amino acid replacements of an epitope of simian immunodeficiency virus (SIV). The region of the tat gene encoding ... -
Skimmer Trawl Modifications to Reduce Bycatch in the Inshore Brown and Pink Shrimp Fishery in North Carolina
(East Carolina University, 1995-06)A study was conducted during May-June 1995 comparing catch composition of a standard high profile skimmer trawl net (12 fi) and a low profile skimmer trawl net (3 fi) in the North and Newport Rivers, North Carolina. Each ... -
Sld5, A Subunit of the Heterotetrameric GINS Complex is Necessary for Normal Cell Cycle Progression and Genomic Stability
(East Carolina University, 2010)Sld5 is one component of the GINS heterotetrameric complex essential to DNA replication. Specifically, GINS is known for its integral role during the G1 to S phase transition in the cell cycle. The GINS complex is comprised ... -
Spatial Ecology and Seasonal Habitat Use of the King Rail (Rallus elegans) along the Atlantic Coast
(East Carolina University, 2014)TThe King Rail (Rallus elegans) continues to experience population declines throughout its range. Due to its secretive nature and occupancy of densely vegetated marshes, little is known about the behavior and ecology of ... -
Spatio-Temporal Expression of Chondroitin Sulfate Antigens in Early Chick Pituitary and Thyroid
(East Carolina University, 2012)The chondroitin sulfate antigens d1C4 and TC2 have been hypothesized to play a role in cartilage differentiation in the limb and early morphogenesis of the heart in chick embryos. The antibody d1C4 recognizes a native ... -
Striped Bass Egg Abundance and Viability in the Roanoke River, North Carolina, and Young-of-Year Survivorship, for 1993
(East Carolina University, 1995-10)Striped bass spawning activity in the Roanoke River, North Carolina, was documented in 1993 by sampling for eggs at Barnhill's Landing (River Mile 117), which is just downstream of the spawning grounds between the towns ... -
Striped Bass Egg Abundance Viability in Scotland Neck, Roanoke River, North Carolina, for 1991
(East Carolina University, 1992-10)From 15 April to 14 June 1991, annual production and viability estimates of striped bass, Morone saxarilis, eggs spawned in the Roanoke River, North Carolina, were determined by sampling downstream of the spawning grounds ... -
A study of composition, abundance, and fatty acid profiles of zooplankton in Albemarle Sound and Chowan River, North Carolina during spring and early summer
(East Carolina University, 2014)In the Albemarle Sound and Chowan River, North Carolina, river herring (alewife and blueback herring) once comprised a commercially important fishery; however, this fishery has since collapsed and a moratorium on river ... -
A Study of the Abundance, Distribution, and Grazing Effects of Zooplankton in the Chlorophyll Maximum (CMAX) of the Neuse River Estuary, North Carolina
(East Carolina University, 2012)Phytoplankton tend to accumulate in distinct zones referred to as chlorophyll maxima, or CMAX. A pronounced CMAX occurs in the Neuse River Estuary (NRE), North Carolina, where as much as over 60% of the estuary's phytoplankton ... -
SYNAPTOPODIN-2 ISOFORM A AND D EXPRESSION IN HT-29 HUMAN COLON ADENOCARCINOMA CELLS
(East Carolina University, 2013)Synaptopodin-2 is a largely unfolded actin-binding protein that also possesses the characteristics of a hub protein. Synaptopodin-2 has other known binding partners such as filamin and [alpha]-actinin (Weins, et al. 2001 ... -
A Synthesis of Red Drum Feeding Ecology and Diets from North Carolina and South Carolina
(East Carolina University, 2014)The trophic interactions of the red drum Sciaenops ocellatus have been previously researched. However diet data on the largest adults (>750mm TL) are very limited. As fisheries management moves towards a goal of multi-species ... -
Tactical reproductive parasitism via larval cannibalism in Peruvian poison frogs
(East Carolina University, 2009-04-23)We report an unusual example of reproductive parasitism in amphibians. Dendrobates variabi- lis, an Amazonian poison frog, oviposits at the surface of the water in small pools in plants and deposits tadpoles within the ... -
Targeting aberrant signaling in the EGFR1/HER2/PI3K/PTEN/Akt/mTORC1/GSK-3 pathway : Novel therapeutic interventions in breast cancer
(East Carolina University, 2015)Breast cancer is attributed to being the second most deadly cancer in American women. Approximately 1 in 8 women will be diagnosed with breast cancer during her lifetime, and prognosis is dependent upon the genetic make-up ... -
Three Generations, One Future: A Systematic Analysis on Nicotine's Effect across generations in C. elegans.
(East Carolina University, 2013)Tobacco smoking is a worldwide epidemic that is responsible for diseases and death rates that surpass those attributed to a combination of other causes (e.g. cancer, HIV, accidents). A major mediator of tobacco-smoke related ... -
TOXICITY OF METAL OXIDE NANOPARTICLES TO CAENORHABDITIS ELEGANS
(East Carolina University, 2012)The increase in manufacturing and use of nanoparticles is expected to elevate levels of exposure to humans and other organisms. Presently, there is little understanding of the potential toxic effects of nanoparticle exposure. ... -
Transcriptional Analysis of the Bacteroides fragilis Starch Utilization Operon, osuA
(East Carolina University, 2011)The opportunistic pathogen Bacteroides fragilis is a symbiotic organism that inhabits the human gastrointestinal tract where it utilizes dietary and host-derived polysaccharides as carbon and energy sources. If abdominal ... -
Tumor Growth Induces Oxidative Clustered DNA Lesions Damage in Distant Mouse Tissue in vivo
(East Carolina University, 2010)Our goal was to ascertain if DNA damage induced by oxidative stress is capable of being exploited as a precancerous or cancer biomarker. The specific DNA damage that we assessed was oxidatively induced non-DSB clustered ... -
