Arsenic--Physiological effect; Cardiovascular system--Diseases; Liver--Effect of arsenic on; Arsenic--Toxicology
Chronic arsenic exposure is associated with increased cardiovascular disease (CVD). Prenatal arsenic exposure at 49 ppm arsenic accelerates atherosclerosis underlying CVD in ApoE-/- mice, but the mechanism is unknown. This dissertation examines the...
Within the Appalachian hills of eastern Kentucky, large-scale coal mining operations are directly altering the headwater landscape through the construction of hollow fills. These man-made landforms and their associated in-stream structures alter a...
Nerves--Regeneration; Spinal cord--Wounds and injuries--Treatment
These studies set out to identify strategies to rescue and repair the adult nervous system. First, we investigated the role of ciliary neurotrophic factor (CNTF) in 5HT1A receptor-induced neurogenesis in the rodent brain. Systemic treatment with an...
Periodontitis--Age factors; Natural immunity; Age factors in disease
Periodontal disease arises from excessive host inflammatory responses to the tooth-associated microbial biofilm, known as dental plaque. Severity ranges from superficial inflammation of the gingivae (gingivitis) to extensive destruction of...
Recent advances in understanding the molecular mechanisms of mutagenesis indicate that most mutations are dependent on the activity of translesion synthesis DNA polymerases. The impact of reducing the level of these polymerases on mutagenesis and...
The inherited bone marrow failure syndromes (IBMFS) encompass a heterogeneous collection of rare disorders characterized by hematological abnormalities, generalized growth delays, and an increased incidence of malignant transformation. These...
Recent studies indicate post-translational deacetylation by members of the superfamily of histone deacetylase complexes (HDACs) is necessary for oligodendrocyte precursor cell (OPC) differentiation into mature oligodendrocytes (OLs). However, it...
Determining the mechanical properties of the spine is a significant step in understanding the behavior of the spine under normal conditions. Although a limited amount of data for cyclic loading is currently available, the tests are not completely...
A potential source of fine grained suspended sediments in a stream system is the
upper hillslopes of the drainage. Quantifying the sediment produced and transported to a
stream from these hillslopes is challenging because of the complex nature of...
Heart--Hypertrophy; Hydrogen sulfide--Therapeutic use
Background: Although matrix metalloproteinase (MMPs) and tissue inhibitor of metalloproteinase (TIMPs) play a vital role in tumor angiogenesis and TIMP-3 causes apoptosis, their role in cardiac angiogenesis is unknown. Interestingly, a disruption...
The goals of this dissertation is to further the understanding of the roles of two genes identified by differential display polymerase chain reaction (ddPCR) of cat visual cortex as candidate genes to play a role in visual cortical plasticity....
Background The anthracycline doxorubicin (DOX) is widely used as an effective antineoplastic drug. Cardiotoxicity leading to congestive heart failure is the primary factor limiting the clinical use of DOX. However, although a variety of approaches...
The fundamental question of the exact nature of the role played by TNF in the failing myocardium remains one of contention. Many preclinical studies have demonstrated beneficial effects with TNF antagonism and recently the dichotomous role played...
Photography--Psychological aspects; Mourning customs in art; Mourning customs in literature; Phenomenology and art
The creation of liminal spaces has been used for centuries cross-culturally to create sacred or taboo meanings in rituals, people, places, or objects. Liminality is constructed by the overlapping of cultural categories and "ruptures" an...
Human adult olfactory epithelium contains neural progenitors (hONPs) which replace damaged cellular components throughout life. Methods to isolate and expand the hONPs have been developed in our laboratory. In response to morphogens, the hONPs...
Ribosomal biogenesis failure may contribute to neurodegenerative diseases, while its excessive activation has been shown to drive tumor growth. As ribosomal production is initiated and regulated by the Pol1-mediated transcription of rRNA genes in...
Chronic periodontitis is strongly associated with composition of the oral biofilm
occupying the gingival crevicular aspect of the tooth and its associated root. Some gram-negative,
"red complex" bacteria instigate periodontal bone loss in...
Spinal cord--Wounds and injuries--Treatment; Physical therapy
Activity-based rehabilitation in the form of overground or body weight-supported treadmill (BWST) locomotor step training has become the most widely accepted therapy translated from preclinical animal research to spinal cord injury (SCI) patients....
Gene therapy; Spinal cord--Wounds and injuries; Tissue engineering
The combination of viral mediated gene delivery, tissue engineering, and Schwann cell (SC) transplantation offer a promising strategy to enhance axonal regeneration and functional recovery following spinal cord injury (SCI). The rationale and...
Embryonic development requires the orchestration of temporally precise genetic events that culminate in the formation of a complete organism. The molecular mechanisms responsible for ontogenesis are regulated by environmental and somatic factors in...
