Studies On The Role Creb As A Mediator Of Neurotrophin-3 Actions In Oligodendrocytes, Jamie Richard Johnson Jan 2000

Studies On The Role Creb As A Mediator Of Neurotrophin-3 Actions In Oligodendrocytes, Jamie Richard Johnson

Theses and Dissertations

In the central nervous system (CNS), oligodendrocytes (OLGs) are the cells responsible for producing the myelin membrane which allows for the saltatory conduction of neuronal impulses. We have previously shown that CREB (cAMP response element binding protein), a transcription factor that belongs to a large family bZip (basic leucine zipper) proteins, could be a mediator of neuronal signals that, coupled to different signal transduction pathways, may play different regulatory roles at specific stages of oligodendrocyte development. We have found before that, in committed OLGs, CREB activation by phosphorylation can be triggered by β-adrenergic stimulation and appears to play a role …

Detection And Modeling Of Radiation Induced Effects In Tissues By Dielectric Spectroscopy, Dorin A. Todor Jan 2000

Detection And Modeling Of Radiation Induced Effects In Tissues By Dielectric Spectroscopy, Dorin A. Todor

Physics Theses & Dissertations

The work presented here is applied physics research in the field of radiation treatment. We address the development of a new and innovative method, in vivo and possibly non-invasive, for tumor and healthy tissues control during and after the radiation treatment. The radiation treatment is delivered in an almost standardized manner for particular classes of tumors. The large variance in the individual radio sensitivity of healthy tissues and tumors often leads to local recurrence of neoplastic growth and/or distant metastatic disease which often remains untreated. The method is based on the measurement and analysis of electrical impedance data in …


Management Of A Bioeroding Sponge On The Pearl Oyster, Pinctada Maxima, Luisa Rawlinson Jan 2000

Management Of A Bioeroding Sponge On The Pearl Oyster, Pinctada Maxima, Luisa Rawlinson

Theses : Honours

This thesis examines environmentally and economically viable ways to manage a sponge that is bioeroding the pearl oyster, Pinctada maxima, in pearl oyster farms throughout north-western Australia. The sponge is causing a massive loss in revenue to the pearling industry as a result of damage to the half-shell, the pearl and, often, death of the oyster. The information arising from this study is important for pearl producers and the Australian pearling industry, to ensure that the best quality P. maxima can be grown in a way that will not have adverse effects on the pristine environment in which these …

An Examination Of The Impact Of Moon Phase On Catch Rates Of The Western Rock Lobster, Petra Roberts

Theses : Honours

The western rock lobster is the most valuable single-species fishery in Australia returning a commercial value of around $250 million annually. This fishery is considered fully exploited and requires careful management to ensure a viable and sustainable fishery. Scientists at Marine Research Laboratory, Western Australia have already built detailed computer models of the lobster fishery and further research is required to continuously update and refine these models to provide an accurate picture of the fishery. One area of interest that could improve this model is the impact of the moon phase, if any, on the daily catch rates of the …


Salinity Tolerance Of Selected Ectomycorrhizal Fungi (Pisolithus Tinctorius Pers.) And Ectomycorrhizal Eucalypts, Ben Bradshaw Jan 2000

Salinity Tolerance Of Selected Ectomycorrhizal Fungi (Pisolithus Tinctorius Pers.) And Ectomycorrhizal Eucalypts, Ben Bradshaw

Theses : Honours

Increasing soil salinity has become a major problem worldwide. It has led to a reduction in the amount of arable land, has put at risk the supply of freshwater and threatens the existence of many natural habitats. The major increase in salinity has been attributed to human activities such as clearing of natural vegetation and large-scale irrigation programmes. The alleviation of this problem has focussed on changed management strategies. the most significant of which is the re-establishment of deep rooted plants in sail affected areas. This, however, is difficult because of the variation in salt tolerance of such plants and …

Effects Of Bac On The Innervation Of Stomach, Berri̇n Gençer Tarakçi Jan 2000

Effects Of Bac On The Innervation Of Stomach, Berri̇n Gençer Tarakçi

Turkish Journal of Veterinary & Animal Sciences

Serosal application of BAC (benzalkonium chloride) to the pyloric antrum of the rat led to a complete loss of the intrinsic innervation of the treated region and also extensive loss of extrinsic sensory projections in the treated and untreated regions of the stomach. However, no changes were seen in the numbers of primary afferents projecting to the stomach, or expression of neuropeptides or neuronal proteins in the neurons. This finding is in marked contrast to the changes reported in sensory cell bodies after sectioning of the sciatic nerve, and suggested that visceral and somatic afferents may respond differently to axonal …


Development Of An Enzyme Immunoassay For The Determination Of Ovine Growth Hormone In Plasma, Behi̇ç Serpek, Seyfullah Hali̇loğlu Jan 2000

Development Of An Enzyme Immunoassay For The Determination Of Ovine Growth Hormone In Plasma, Behi̇ç Serpek, Seyfullah Hali̇loğlu

Turkish Journal of Veterinary & Animal Sciences

A competitive enzyme immunoassay for the determination of ovine growth hormone (oGH) was developed. The assay is based on (anti-rabbit IgG) goat IgG-coated microtitreplates, anti-oGH from rabbits, biotinyl-oGH and streptavidin-horseradish peroxidase. The assay is done directly with 40 ml of plasma and the calibration graph (90% relative binding at 0.38 ± 0.02 ng ml -1 and 50% relative binding at 3.80 ± 0.18 ng ml -1 ) is prepared in plasma without measurable endogenous oGH. Recovery in different plasma samples with added oGH amounted to 96.78 - 100.03 %, and all variabilities were < 10.44. The assay shows no significant binding of oFSH, oLH, oTSH and oPRL. The assay detects high and low plasma oGH levels within the physiological variation as well as changes in plasma oGH after stimulation with growth hormone releasing factor. Hence, it offers a reliable alternative radioimmunoassay. However, a reference method providing evidence of the identity of exogenous oGH will be required for proving illegal treatment with oGH and for forensic purposes.
