  1. The Synthesis and biological testing of nucleoside derivatives
    Panayides, Jenny-Lee, 2012-10-05T10:03:31Z
    As a first generation of compounds, the nucleosides adenosine 8, cytidine 11, guanosine 9, inosine 116 and uridine 12, as well as the sugar ᴅ-(-)-ribose 100, were transformed into the corresponding 5’-O-(tert-butyldiphenylsilyl)- and 5’-O-(4,4’-dimethoxytrityl)-derivatives. These were subsequently p ...
  2. The utilization of second generation feedstocks for the production of platform chemicals by filamentous fungi
    Hu, Ziyi, 2012-10-05T10:11:08Z
    The depletion of petroleum and other platform chemical resources are a global concern; therefore alternative substrates must be identified to replace these current sources. Thus allowing research in fungal biotechnology to prosper, as filamentous fungi can utilize second-generation feedstocks or ...
  3. Stress response to genotoxic agents and to infection
    Hull, Rodney, 2012-10-08T04:56:10Z
    Insects have evolved various physiological responses to cope with stressors such as pathogens, toxins and environmental factors. It is known that the responses resulting from infection or DNA damage share some of the same pathways. Exposure of Drosophila melanogaster and the dung beetle Euonitice ...
  4. Molecular analysis of the domain with no name (DWNN)/RBBP6 in human cancers
    Mbita, Zukile, 2012-10-08T05:00:29Z
    Retinoblastoma binding protein 6 (RBBP6) is a nuclear protein, previously implicated in the regulation of cell cycle and apoptosis. It is a multi-domain protein containing a Zinc finger, a RING finger, an Rb binding domain, a p53 binding domain and a novel N-terminal protein domain, the so called, D ...
  5. Taxonomic variation, species limits and Phylogenetic relationships in Oliniaceae
    Sebola, Ramagwai Joseph, 2012-10-08T05:07:38Z
    A new classification of the Oliniaceae is presented. The monogeneric Oliniaceae is one of the smallest, but lesser known myrtalean families that has not been monographed since Cufodontis’ (1960) revision, despite advances in analytical tools. In this thesis, a combination of morphometric phenetic (p ...
