Molecular analysis of herpes simplex virus type 1 latency in experimentally infected mice / Barry Slobedman.

Slobedman, Barry January 1994 (has links)
Copies of author's previously published articles inserted inside back cover. / Bibliography: leaves 137-179. / x, 179, [26] leaves, [28] leaves of plates : ill. ; 30 cm. / Title page, contents and abstract only. The complete thesis in print form is available from the University Library. / The aims of this study are to determine whether latent HSV genomes are a result of viral DNA amplification in the PNS during the establishment phase and to investigate the relationship between HSV DNA copy number and viral transcriptional activity during latent infection of the PNS. In order to map the distribution of viral nucleic acid sequences in latently infected sensory ganglia, experiments are undertaken using a mouse model that makes novel use of the segmental sensory innervation of flank skin. / Thesis (Ph.D.)--University of Adelaide, Dept. of Microbiology and Immunology, 1995?

Enzyme replacement therapy in a murine model of mucopolysaccharidosis type IIIA / by Briony Lee Gliddon.

Gliddon, Briony Lee January 2002 (has links)
Addenda page on inside back cover. / Bibliography: leaves 153-176. / xiii, 176 leaves ; ill. (some col.) ; 30 cm / Title page, contents and abstract only. The complete thesis in print form is available from the University Library. / Mucopolysaccharideosis type IIIA (MPS IIIA, Sanfilippo A syndrome) is an autosomal recessive lysosomal storage disease, with a prevalence in Australia of 1 in 114,000. MPS IIIA is caused by a deficiency of the lysosomal enzyme sulphamidase which is needed together with other exohydrolases and a N-acetyltransferase to break down the glycosaminoglycan heparan sulphate to sulphate and monosaccharides. Patients are characterised by severe central nervous systems degeneration together with mild somatic involvement; this disproportionate correlation is unique amongst the mucopolysaccharidoses. Features include severe behavioural disturbances, such as hyperactivity and aggressiveness, coarse hair and mild hepatosplenomegaly. Death is usually in the mid- to late-teenage years. Enzyme replacement therapy by intravenous administration of recombinant human NS (rhNS) has been proposed as a potential therapy for MPS IIIA. This thesis suggests that rhNS, entering the brain in the first few weeks of life, is able to retard the behaviour and learning difficulties in MPS IIIA mice. / Thesis (Ph.D.)--University of Adelaide, Dept. of Paediatrics, 2003

Temperature monitoring during transport of test samples

Holm, Perbie January 2006 (has links)
<p>Quality is the main focus in management of all laboratories. Accurate results of the analyses are not only determined by the analytical procedure but also by preanalytical factors. In the total analytical process of clinical specimens, there are many possible preanalytical sources of error. Monetoring of temperature on test samples of the transport boxes is one way to reduce the mistakes in the preanalytical phase.</p><p>In this study, four laboratories from primary health care were invited to participate. The temperature has been measured on test samples of the transport boxes being delivered to the laboratory.</p><p>In three cases the temperature remained within the limits, but in the fourth case the temperature varied more than the allowed interval. Mistakes found in the preanalytical phase, especially in the handling and processing in the process before complete distribution of test samples to laboratory. This suggests that good communication and cooperation among the personnel is the key to improvement of the laboratory quality.</p>

Enhancement of anaerobic biodegradation of petroleum hydrocarbons in contaminated groundwater: laboratory mesocosm studies

Fan, Xiaoying 06 1900 (has links)
This project was a part of a study to evaluate natural attenuation (NA) as a viable remedial option for petroleum hydrocarbon (PHC) contamination at upstream oil- and gas-contaminated sites in Alberta, Canada. Laboratory mesocosms were set up using groundwater and sediment materials collected from two PHC contaminated sites (Site 1 and Site 3) in Alberta to investigate the enhancement of anaerobic PHC biodegradation by amendment of terminal electraon acceptors (TEAs, nitrate or sulfate) and/or nutrients (ammonium and phosphate). Multiple lines of evidence, including the removal of benzene, toluene, ethylbenzene and xylenes (BTEX) and CCME F1 fraction hydrocarbons (C6 to C10), rapid depletion of TEAs, the production of biogenic gases, and detection of the metabolites verified that anaerobic PHC biodegradation was occurring in both laboratory mesocosm studies. Selective biodegradation of PHCs under different reducing conditions was observed. However, there was no conclusive evidence that one reducing condition will universally favor the biodegradation of specific PHCs. In both studies, nutrient amendment showed no enhancement effects. The calculated first-order biodegradation rates in Site 1 mesocosm study ranged from 0.0032 to 0.033 d-1 for benzene, 0 to 0.028 d-1 for ethylbenzene, 0.0021 to 0.036 d-1 for m-, p-xylenes, and 0.0006 to 0.0045 d-1 for F1-BEX (F1 hydrocarbons exclduding BEX) under the tested conditions. The laboratory first-order biodegradation rates of BEX were higher than the estimated field rates, indicating the potential of enhanced anaerobic biodegradation in situ. However, when comparing the TEA amended mesocosms with the unamended controls (in which iron reduction might be the predominant process), the enhancement effects were less apparent and inconsistent. The calculated first-order biodegradation rates in Site 3 mesocosm study ranged from 0 to 0.0009 d-1 for benzene, 0 to 0.011 d-1 for ethylbenzene, 0 to 0.0016 d-1 for m- and p-xylenes, and 0 to 0.15 d-1 for o-xylene. Sulfate amendment significantly stimulated biodegradation of all xylenes and CCME F1 hydrocarbons. However, there was no definitive evidence that nitrate or sulfate amendment could enhance benzene or ethylbenzene biodegradation. / Environmental Engineering

Multi-unit common value auctions : theory and experiments

Ahlberg, Joakim January 2012 (has links)
Research on auctions that involve more than one identical item for sale was,almost non-existing in the 90’s, but has since then been getting increasing attention. External incentives for this research have come from the US spectrum, sales, the European 3G mobile-phone auctions,  and Internet auctions. The policy relevance and the huge amount of money involved in many of them have helped the theory and experimental research advance. But in auctions where values are equal across bidders, common value auctions, that is, when the value depends on some outside parameter, equal to all bidders, the research is still embryonic. This thesis contributes to the topic with three studies. The first uses a Bayesian game to model a simple multi-unit common value auction, the task being to compare equilibrium strategies and the seller’s revenue from three auction formats; the discriminatory, the uniform and the Vickrey auction. The second study conducts an economic laboratory experiment on basis of the first study. The third study comprises an experiment on the multi-unit common value uniform auction and compares the dynamic and the static environments of this format. The most salient result in both experiments is that subjects overbid. They are victims of the winner’s curse and bid above the expected value, thus earning a negative profit. There is some learning, but most bidders continue to earn a negative profit also in later rounds. The competitive effect when participating in an auction seems to be stronger than the rationality concerns. In the first experiment, subjects in the Vickrey auction do somewhat better in small groups than subjects in the other auction types and, in the second experiment, subjects in the dynamic auction format perform much better than subjects in the static auction format; but still, they overbid. Due to this overbidding, the theoretical (but not the behavioral) prediction that the dynamic auction should render more revenue than the static fails inthe second experiment. Nonetheless, the higher revenue of the static auction comes at a cost; half of the auctions yield negative profits to the bidders, and the winner’s curse is more severely widespread in this format. Besides, only a minority of the bidders use the equilibrium bidding strategy.The bottom line is that the choice between the open and sealed-bid formats may be more important than the choice of price mechanism, especially in common value settings.
