Effects Of Novel Synthetic Nucleosides As Anti-Tumor Agents On Human Acute Promyelocytic Leukemia Cell Line (Hl-60), Salma Awad Merghani Mahmoud

Theses

Nucleosides and their analogs are considered a clinically proven class of therapeutic agents possessing anticancer and antiviral activity. Several trifluoromethyl-substituted pyrazole N-nucleosides (coded NIA, NIIA and NIIA) and their nucleobases were synthesized and tested for the ability to induce apoptosis in acute human promyelocytic cell line (HL-60). The growth and proliferation of HL-60 was more effectively inhibited by NIA, NIIA and their nucleobases compared to NIIIA and its nucleobase. In addition, DNA fragmentation was detected in a concentration-dependent manner as a result of nucleosides treatment. A caspase-3-dependent apoptosis was observed based on the Western blot analysis of poly-ADP-ribose polymerase (PARP) …

The Aeolian Flux Of Calcium, Chloride And Nitrate To The Mcmurdo Dry Valleys Landscape: Evidence From Snow Pit Analysis, Rebecca A. Witherow, W. Berry Lyons, Nancy A. Bertler, Kathleen A. Welch, Paul A. Mayewski, Sharon B. Sneed, Thomas H. Nylen, Michael J. Handley, Andrew G. Fountain

Geography Faculty Publications and Presentations

We have determined the flux of calcium, chloride and nitrate to the McMurdo Dry Valleys region by analysing snow pits for their chemical composition and their snow accumulation using multiple records spanning up to 48 years. The fluxes demonstrate patterns related to elevation and proximity to the ocean. In general, there is a strong relationship between the nitrate flux and snow accumulation, indicating that precipitation rates may have a great influence over the nitrogen concentrations in the soils of the valleys. Aeolian dust transport plays an important role in the deposition of some elements (e.g. Caý?) into the McMurdo Dry …

Iron In Ice Cores From Law Dome: A Record Of Atmospheric Iron Deposition For Maritime East Antarctica During The Holocene And Last Glacial Maximum, Ross Edwards, Peter N. Sedwick, Vin Morgan, Claude Boutron

OES Faculty Publications

Total dissolvable iron (TDFe) was measured in sections of ice cores recovered from Law Dome on the coast of Wilkes Land, East Antarctica. These samples include ice dating from the Last Glacial Maximum (LGM), the Last Deglaciation, and the early and mid Holocene as well as samples from the Anthropocene that have been dated with seasonal to annual resolution. Combining our TDFe concentration data with estimates of the ice accumulation rate, we estimate the atmospheric iron deposition for Law Dome and the adjacent Southern Ocean during these periods. Our results indicate that the atmospheric iron deposition flux to this region …

Sources Of Nitrogen And Phosphorus In Stormwater Drainage From Established Residential Areas And Options For Improved Management, Surasithe Khwanboonbumpen

Theses: Doctorates and Masters

From early April 2002 to June 2003, a study was conducted at Wanneroo and Bannister Creek in Perth's metropolitan area (Western Australia), aiming to quantify major sources of nitrogen (N) and phosphorus (P) entering urban residential catchments on two of the major dunal systems. The export of N and P from these catchments in stormwater discharge was measured, allowing investigation of some of the key pathways through which N and P enter the drainage network from the catchment. This information was then used to recommend catchment management approaches to reduce nutrient discharge into stormwater.

Fisheries Research Report No. 152 - Development Of A Dna Database For Compliance And Management Of Western Australian Sharks., Rory Mcauley, K. Ho, R. Thomas

Fisheries Research Reports

Final FRDC Report - Project 2003/067

The capability to identify individual shark species from processed body parts is necessary for the WA Department of Fisheries to ensure the compliance of all WA fisheries with both existing protected species regulations and proposed new management measures for commercially important shark species. This project established a reference database of genetic profiles or ‘fingerprints’ for nine of Western Australia’s protected and commercially important shark species. Fingerprints from a 10th species, the shortfin mako (Isurus oxyrinchus) could not be obtained due to probable primer sequence mismatching. The database, in conjunction with an associated inspection and …

Spatial Autocorrelation Of Deer-Vehicle Accidents In Vigo County, J. Scott Horn

All-Inclusive List of Electronic Theses and Dissertations

Deer-vehicle accidents (DV As) are a problem in many areas. They cause millions of dollars in property damage, personal injury, and loss of life each year. This thesis examines whether DVAs in Vigo County, Indiana during the year 2000 were spatially autocorrelated; and whether DV As selected by deer habitat were spatially autocorrelated. Specifically using Moran's I to test for spatial autocorrelation this study determined if and to what degree spatial autocorrelation existed among these DVAs. A Moran's I value of .0023 shows that the accidents occurred randomly. These DV A data were then used to plot a map which …
