HOW CAN WE REDUCE THE EFFECTS OF ENVIRONMENTAL POLLUTANTS ON THE PLACENTA?
(East Carolina University, 2020-11-19)Prenatal exposure to endocrine disrupting chemicals can lead to birth defects and adult disease. While it is impossible to avoid pollutant exposure, development of a prenatal supplement that augments natural protective ... -
How do modified nanoclays adversely affect aquatic species relative to natural nanoclay?
(East Carolina University, 2017-07-17)Nanoclays represent a large class of modified nanomaterials (NMs) (i.e. nanoscale particles from 1 to 100 nm) that has received great attention from the scientific and industrial communities. This material has been widely ... -
Hox Gene Expression During Oreochromis niloticus Pharyngeal Arch Development : Discovering the Hox Code
(East Carolina University, 2010)Hox genes encode transcription factors and have been extensively studied by evolutionary and developmental biologists. Hox genes are responsible for determining specific regional identities along the anterior-posterior and ... -
HUMAN T-CELL LEUKEMIA VIRUS TYPE 1-ENCODED PROTEIN HBZ INCREASES VIRAL INFECTION
(East Carolina University, 2017-05-04)Human T-lymphotropic virus type 1 (HTLV-1) is a complex retrovirus, infecting CD4+ T lymphocytes. About 10 million people worldwide are infected with HTLV-1. HTLV-1 has been linked to adult T-cell leukemia (ATL), a disease ... -
Hybridization in two subspecies of triodanis perfoliata, a cleistogamous annual plant (campanualaceae)
(East Carolina University, 2013)The presence of a cleistogamous (obligately selfing) plant breeding system may have implications for reproductive isolation between species. The effects of this trait on plant hybridization previously have received little ... -
Hydrogeomorphology and Horizontal Movement of Juncus roemerianus
(East Carolina University, 2015)Juncus roemerianus, black needlerush, is common in high marshes and occasionally in low marshes along the Mid-Atlantic and southern USA. Previous work found that J. roemerianus patches remained relatively stable in the ... -
Hypoxia and Serum Deprivation in Human Mesenchymal Stem Cells, and the Protective Role of Thymosin [Beta]-4
(East Carolina University, 2011)Background: Current literature suggests nutrient deprivation and hypoxia affect human mesenchymal stem cell (hMSC) survival after cell transplantation. Wound-healing protein Thymosin [beta]-4 (T[beta]-4) has been shown ... -
Identification and mapping of two divergent, unlinked major histocompatibility complex class II B genes in Xiphophorus fishes.
(East Carolina University, 1998-08)We have isolated two major histocompatibility complex (MHC) class II B genes from the inbred fish strain Xiphophorus maculatus Jp 163 A. We mapped one of these genes, designated here as DXB, to linkage group III, linked ... -
Identification of a Potential RNAzyme in Brucella abortus with Heme-Dependent Peroxidase Activity
(East Carolina University, 2020-11-19)Bovine brucellosis is of significant concern to the U.S. cattle industry and has not been controlled by vaccination in some areas of the world. The inability to control this pathogen is currently a serious public health ... -
IDENTIFICATION OF GEOCHEMICAL TRACERS WITHIN BIOMINERALS OF JUVENILE AND LARVAL MERCENARIA MERCENARIA : IMPLICATIONS FOR MODELING LARVAL DISPERSAL
(East Carolina University, 2013)This study was designed to investigate the application of geochemical signals within biominerals to identify site fidelity and natal origin of the commercially valuable bivalve Mercenaria mercenaria. My first study ...
