Historical Ecology of Striped Bass Stocking in the Southeastern United States
(East Carolina University, 2012)Striped bass (Morone saxatilis) is the most recreationally and commercially important non-salmonid fish species in the continental United States. As such, it has been exploited to the point of collapse at various points ... -
HORIZONTAL GENE TRANSFER (HGT) AND SPHAGNUM FALLAX: A PHYLOGENETIC LOOK INTO THE OCCURRENCE, PREVALENCE, AND IMPORTANCE OF HORIZONTAL GENE TRANSFER IN A BOG MOSS
(East Carolina University, 2020-11-04)Horizontal gene transfer (HGT) is a biological process that involves any transmission of genetic material that isn't vertical in nature. HGT occurs frequently between prokaryotes and plays a significant role in prokaryotic ... -
Horizontal gene transfer of epigenetic machinery and evolution of parasitism in the malaria parasite Plasmodium falciparum and other apicomplexans
(2013)Background The acquisition of complex transcriptional regulatory abilities and epigenetic machinery facilitated the transition of the ancestor of apicomplexans from a free-living organism to an obligate parasite. The ... -
Hormone Exposure During Pregnancy and Maternal Care
(East Carolina University, 2015-12-17)It is suspected that prenatal hormones can affect maternal care, which has important implications for the neurological development of pups. To determine if the altered hormone levels affected maternal care, pregnant dams ... -
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 ...
