A dominant allele controls development into female mimic male and diminutive female ruffs
(2013-12)Maintaining polymorphisms for genes with effects of ecological significance may involve conflicting selection in males and females. We present data from a captive population of ruffs (Philomachus pugnax) showing that a ... -
Drosophila Ctf4 is essential for efficient DNA replication and normal cell cycle progression
(2011)Background Proper coordination of the functions at the DNA replication fork is vital to the normal functioning of a cell. Specifically the precise coordination of helicase and polymerase activity is crucial for efficient ... -
Drosophila Ctf4 is essential for genome stability and normal cell cycle progression
(East Carolina University, 2010)Proper DNA replication and well-timed cell cycle progression are vital to the normal functioning of a cell. Precise coordination between these mechanisms' constituent proteins ensures their processivity while safeguarding ... -
Drosophila Oocytes as a Model for Understanding Meiosis: An Educational Primer to Accompany “Corolla Is a Novel Protein That Contributes to the Architecture of the Synaptonemal Complex of Drosophila”
(2015-01)Achieving a thorough understanding of the events and ramifications of meiosis is a common learning objective for undergraduate introductory biology, genetics, and cell biology courses. Meiosis is also one of the most ... -
Drosophila Ovarian Stem Cell Establishment is Regulated by Nuclear Hormone Receptor ftz-f1
(East Carolina University, 2017-06-28)Stem cells are a fundamental underpinning of tissue biology. Loss of the self-renewing function of stem cells leads to conditions such as infertility and tissue wasting. Stem cells integrate a variety of signals to maintain ... -
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, ... -
Duodenal carcinoma at the ligament of Treitz. A molecular and clinical perspective
(2010)Background There is very small occurrence of adenocarcinoma in the small bowel. We present a case of primary duodenal adenocarcinoma and discuss the findings of the case diagnostic modalities, current knowledge on the ... -
EARLY LIFE HISTORY OF LARVAL RIVER HERRING IN A COASTAL WATERSHED: ABUNDANCE, GROWTH, AND MORTALITY
(East Carolina University, 2017-12-18)River herring are two closely-related, anadromous fish species, Alewife (Alosa aestivalis) and Blueback Herring (A. pseudoharengus), which have been historically, commercially, and ecologically important along the North ... -
Early Nicotine Exposure Altered Larval Neuromuscular Function and Adult Germline Apoptosis via MiRNA-Dependent Mechanisms
(East Carolina University, 2016-04-29)MicroRNAs fine tune the expression of target genes needed for homeostasis. Our pilot study showed that nicotine altered 17% miRNAs in C. elegans larvae. Here, we investigated the role of microRNAs in mediating nicotine-induced ... -
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 ... -
Educational engagement and the environment: Investigating service learning in the nonhuman sciences
(2014)Classic definitions outline service learning as engaging students in experiential education where learning goals are reached when service activities are combined with reflective assignments. In an effort to integrate ... -
THE EFFECT OF CHANGES IN SODIUM CONCENTRATIONS ON MITOCHONDRIA
(2015-05-01)Atherosclerosis, hardening of the arteries, is the major cause of stroke, peripheral artery disease and heart attack. . Overproduction of superoxide anions in mitochondria can give rise to atherosclerosis. Superoxide anions ...
