Cytotoxic Effects Of Ruthenium Compounds On Human Cancer Cell Lines., Katie Beth Brown

Electronic Theses and Dissertations

Chemotherapy is the most common cancer treatment. Traditionally, platinum-based drugs are used in chemotherapy. More recently, researchers have focused on ruthenium based compounds as a substitute for the platinum compounds. Ruthenium-based compounds appear to be less toxic to healthy cells than traditional platinum-based compounds. In this study, 7 ruthenium-based compounds were tested on HT-29 (colon) and MCF-7 (breast) human cancer cell lines with the specific aim of determining whether or not any of the ruthenium-based compounds exhibited cytotoxic properties. In addition, levels of vascular endothelial growth factor (VEGF) production were tested in supernate from the cancer cells treated with various …

Characterization Of The Genes Involved In Biosynthesis And Transport Of Schizokinen, A Siderophore Produced By Rhizobium Leguminosarum Iari 917., David Jack Hammond

Electronic Theses and Dissertations

Iron is the 4th most abundant metal on the earth's crust and is required by most organisms as a cofactor for many enzymes; however, at physiological pH and aerobic conditions iron forms insoluble ferric oxyhydroxide polymers. Siderophores are low molecular weight compounds that scavenge ferric ions, bind with high affinity, and transport it into the cell via multicomponent transport systems. Rhizobia are soil dwelling organisms that form symbiotic relationships with host plants and fix atmospheric nitrogen, while the bacteria receive nutrients. R. leguminosarum IARI 917 produces a siderophore characterized as 'schizokinen'. In the present study, we have characterized the binding …

Characterization Of Murine Cardiac Cholinergic Innervation And Its Remodeling In Type 1 Diabetes., Abigail Marie Mabe

Electronic Theses and Dissertations

Murine models have become increasingly popular to study various aspects of cardiovascular diseases due to their ease of genetic manipulation. Unfortunately, there has been little effort put into describing the distribution of autonomic nerves in the mouse heart, making it difficult to compare current findings from clinical and experimental models related to cardiovascular diseases. Furthermore, determination of the requirements for the development of this system and its maintenance in adult mice remains largely unexplored. This study represents the first detailed mapping of cholinergic neuroanatomy of the mouse heart based on immunohistochemical staining using true cholinergic markers. We found cholinergic innervation …

Medicaid Financing: How The Fmap Formula Works And Why It Falls Short, Christie Provost Peters

National Health Policy Forum

Medicaid costs for health and long-term care services for low-income individuals are substantial. As a result, each state’s “match rate,” or federal medical assistance percentage (FMAP), which determines the share of Medicaid benefit costs the federal government pays, has enormous implications for state budgets and state economies, as well as for Medicaid beneficiaries and providers. Shifts in the FMAP from year to year, even minor ones, can mean the gain or loss of tens or hundreds of millions of federal matching dollars, depending on the size of the state’s Medicaid program. This paper explains the FMAP formula, examines the limitations …

Neural Substrates Of Sound–Touch Synesthesia After A Thalamic Lesion, Michael S. Beauchamp, Tony Ro

Publications and Research

Neural plasticity induced by stroke can mediate positive outcomes, such as recovery of function, but can also result in the formation of abnormal connections with negative consequences for perception and cognition. In three experiments using blood-oxygen level dependent (BOLD) functional magnetic resonance imaging, we examined the neural substrates of acquired auditory-tactile synesthesia, in which certain sounds can produce an intense somatosensory tingling sensation in a patient with a thalamic lesion. Compared with nine normal controls, the first experiment showed that the patient had a threefold greater BOLD response to sounds in the parietal operculum, the location of secondary somatosensory cortex. …

Gender Specific Differences In The Pros And Cons Of Smoking Among Current Smokers In Eastern Kentucky: Implications For Future Smoking Cessation Interventions, Dana A. Hazen, David M. Mannino, Richard Clayton

David M. Mannino

This study investigated gender differences in the perceived “pros” and “cons” of smoking using the constructs of decisional balance (DB) and stage of change from the Transtheoretical Model. The population distribution for stage of change among a population-based, cross-sectional survey of 155 current smokers over 40 years was: precontemplation (22.6%), contemplation (41.9%), preparation (35.5%). Results of stepwise regression models indicated significant gender differences in DB were in the preparation stage of change; scores on the DB measure increased 3.94 points (95% CI: 1.94, 5.93) for male smokers. Interventions targeting the “pros” and “cons” of smoking may need to be gender …

Scan-Rescan And Intra-Observer Variability Of Magnetic Resonance Imaging Of Carotid Atherosclerosis At 1.5 T And 3.0 T, Arvin Vidal, Yves Bureau, Trevor Wade, J David Spence, Brian K Rutt, Aaron Fenster, Grace Parraga

Medical Biophysics Publications

Carotid atherosclerosis measurements for eight subjects at baseline and 14 +/- 2 days later were examined using 1.5 T and 3.0 T magnetic resonance imaging (MRI). A single observer blinded to field strength, subject and timepoint manually segmented carotid artery wall and lumen boundaries in randomized images in five measurement trials. Mean increases in the signal-to-noise ratios (SNR) for T1-weighted images acquired at 3.0 T compared to 1.5 T were 90% (scan) and 80% (rescan). Despite significantly improved SNR and contrast-to-noise ratios (CNR) for images acquired at 3.0 T, vessel wall volume (VWV) intra-observer variability was not significantly different using …

Glypican-1 Modulates The Angiogenic And Metastatic Potential Of Human And Mouse Cancer Cells, Takuma Aikawa, Chery A. Whipple, Martha E. Lopez, Jason Gunn, Alison Young, Arthur D. Lander, Murray Korc

Dartmouth Scholarship

Cells isolated from many types of human cancers express heparin-binding growth factors (HBGFs) that drive tumor growth, metastasis, and angiogenesis. The heparan sulfate proteoglycan glypican-1 (GPC1) is a coreceptor for HBGFs. Here we show that both cancer cell–derived and host-derived GPC1 are crucial for efficient growth, metastasis, and angiogenesis of human and mouse cancer cells. Thus downregulation of GPC1 in the human pancreatic cancer cell line PANC-1, using antisense approaches, resulted in prolonged doubling times and decreased anchorage-independent growth in vitro as well as attenuated tumor growth, angiogenesis, and metastasis when these cells were transplanted into athymic mice. Moreover, athymic …
