Bioenergetics and Trophic Impacts of Invasive Indo-Pacific Lionfish
(East Carolina University, 2010)Indo-Pacific lionfish, Pterois volitans and Pterois miles, are non-native marine fish with established populations in the western North Atlantic Ocean and Caribbean Sea. Rapid population growth threatens native fish ... -
CAN NUTRIENT ADDITIONS MEDIATE GAPE LIMITED PREDATION IN LARVAL RANA SPHENOCEPHALA?
(East Carolina University, 2013)Some predators are limited in the size prey item that they can catch and consume, and this is referred to as "gape limited". Prey found with these predators may have the ability to respond by growing rapidly to reach a ... -
Can Passive Acoustics be Used to Estimate the Length of Atlantic Croaker (Micropogonias undulatus) within the Pamlico Estuary?
(East Carolina University, 2010)The Atlantic States Marine Fisheries Council (AFMFC) attributes the decline in the Atlantic croaker (Micropogonias undulatus) stock to over-fishing practices. The majority of collected Atlantic croaker are small, young of ... -
Cardiac and Mitochondrial Adaptations in Response to Aging and Doxorubicin in Rats Bred for Divergent Aerobic Capacities
(East Carolina University, 2012)Doxorubicin (DOX) remains as one of the most widely prescribed and effective anticancer agents. A major limitation of the therapeutic effectiveness of the drug is the occurrence of irreversible, progressive, dose-dependent ... -
CHARACTERIZATION OF MIGRATING NEURAL CREST CELLS FROM HINDBRAIN EXPLANTS IN ZEBRAFISH
(East Carolina University, 2010)Our lab was interested in creating a reproducible mechanism for obtaining neural crest cells in culture from cultured hindbrain explants of zebrafish. We have characterized the population of cells migrating from the ... -
Characterization of Site-Directed Mutants in the Cytochrome c-550 Protein of Photosystem II
(East Carolina University, 2010)Photosynthesis is the process by which cyanobacteria, algae, and higher plants convert light energy to chemical energy via the biosynthesis of carbohydrates. Photosystem II is a multi-protein/pigment complex embedded in ... -
Characterization of the GINS subunit psf1 in Drosophila Melanogaster
(East Carolina University, 2010)GINS (Go Ichi Ni San; 5,1,2,3 in Japanese) is a heterotetrameric protein complex known to be essential for the establishment of DNA replication forks and the progression of the replisome. The GINS complex is known to be ... -
Coevolutionary analysis of Appalachian Xystodesmid millipedes and their symbiotic Mesostigmatid mites
(East Carolina University, 2010)Mites (Acari) form symbiotic relationships with many animal taxa including fish, amphibians, reptiles, birds, mammals, mollusks, and arthropods. They are frequently found living on millipedes, and it has often been ... -
Consequences of Reduced Versican Expression in Embryonic Chick Synovial Joint Development
(East Carolina University, 2012)The different mechanisms involved in vertebrate synovial joint development are actively being uncovered. A variety of studies have thus far discovered the involvement of several large molecules in the processes of joint ... -
Conspicuous female ornamentation and male mate preference of Threespine Sticklebacks (Gasterosteus aculeatus)
(East Carolina University, 2012)Sexual selection drives the evolution of exaggerated male ornaments (traits showing little function outside social interactions) in many animal species. Female ornamentation is now acknowledged also to be common but is ... -
Does history matter? : An experimental assessment of whether dragonfly colonization history affects insect biodiversity within ephemeral ponds
(East Carolina University, 2010)Current interactions among species could have an important role in controlling biodiversity. Some studies, however, have shown that the particular time a species arrives at a site during the process of community assembly ... -
DOES THE QUANTITY OF RESOURCES IN THE ENVIRONMENT ALTER THE IMPACT OF MULTIPLE PREDATORS ON THEIR PREY?
(East Carolina University, 2013)Predation is an important biological process affecting prey populations and most prey in nature are exposed to multiple predator species. Much research has revealed that the combined effect of multiple predators on their ... -
Drosophila Psf2 Has a Role In Chromosome Condensation
(East Carolina University, 2012)The condensation state of chromosomes is a critical parameter in multiple processes within the cell. Failures in the maintenance of appropriate condensation states may lead to genomic instability, mis-expression of genes, ... -
Ecological effects of rising sea level on shorezone
(East Carolina University, 2009)This study examines the ecological effects of sea-level rise on shorezone in the Neuse River estuary and western Pamlico Sound, NC. Shorezone is defined here in an ecohydrological context as the area of wetland that extends ... -
Effect of green tea Polyphenon 60 on microRNA expression in MCF-7 breast cancer cells
(East Carolina University, 2010)In Western countries, breast cancer is the most common form of cancer and it is the second leading cause of female cancer death in America. The biochemical basis of the observed anti-oncogenic properties of green tea has ... -
Effects of 5-fluorouracil Drug Treatment on the Expression Profile of MicroRNAs in MCF7 Breast Cancer Cells
(East Carolina University, 2010)Breast cancer is one of the leading causes of deaths in women worldwide. 5-flourouracil (5-FU) is a classic chemotherapeutic drug that has been widely used in the treatment of breast cancer patients. In this study, using ... -
The effects of environmental nickel toxicity upon survival, growth, reproduction, fecundity, and lifespan of nematodes Caenorhabditis elegans, Pristionchus pacificus, and Caenorhabditis briggsae
(East Carolina University, 2012)Nickel (II) is a common component of many natural products and man-made devices. Due to its frequent use in everyday life, relatively large amounts of nickel are being released into the environment. Nickel, however, is a ... -
The Effects of Gastrin and Hox-A1 on HT-29 Cell Proliferation
(East Carolina University, 2013)Gastrin is a gastrointestinal peptide hormone synthesized in G cells and secreted in the antrum of the stomach. Though its primary role is to stimulate the secretion of gastric acid by parietal cells, it is also involved ... -
Effects of Modified Vaccinia Virus Ankara Expressing Mesothelin and the Poxvirus Immunoregulatory A35R gene in the Treatment of Murine Pancreatic Cancer
(East Carolina University, 2012)Pancreatic cancer is the fourth leading cause of cancer-related deaths in the United States. Pancreatic tumors over-express the protein mesothelin, and therefore, it is used as a tumor target antigen for vaccine development. ... -
