Polyadenylation Of Vesicular Stomatitis Virus Mrna Dictates Efficient Transcription Termination At The Intercistronic Gene Junctions, Leroy N. Hwang, Nathan Englund, Asit K. Pattnaik

School of Veterinary and Biomedical Sciences: Faculty Publications

The intercistronic gene junctions of vesicular stomatitis virus (VSV) contain conserved sequence elements that are important for polyadenylation and transcription termination of upstream transcript as well as reinitiation of transcription of downstream transcript. To examine the role of the putative polyadenylation signal 3' AUACU75' at the gene junctions in polyadenylation and transcription termination, we constructed plasmids encoding antigenomic minireplicons containing one or two transcription units. In plasmid-transfected cells, analyses of the bicistronic minireplicon containing the wild-type or mutant intercistronic gene junctions for the ability to direct synthesis of polyadenylated upstream, downstream, and readthrough mRNAs showed that the AUACU …


Molecular Analysis Of The Factor V-Leiden Mutation In A Cardiac Transplant Patient Population, Caroline Maher Jan 1998

Molecular Analysis Of The Factor V-Leiden Mutation In A Cardiac Transplant Patient Population, Caroline Maher

Theses

Venous thrombosis is a serious health problem affecting 1 in 1000 individuals annually. Until recently the pathogenic factors underlying thrombosis were associated with genetic defects in protein C, protein S and antithrombin III. However these were recognised in fewer than 5-10% of thrombotic patients. A breakthrough was made with the discovery of activated protein C resistance (APCr) which is associated in 90% of cases v/herein a G-->A transition in the factor V gene results in an abnormal molecule, Factor V Leiden. APCr is a major risk factor for thrombosis being present in 20-60% of thrombotic patients. Recently a G-^A …


In Vivo And In Vitro Nuclear Magnetic Resonance Imaging And Spectroscopy Of Psychoactive Drugs In Rat Brain, Diana M. Lindquist Jan 1998

In Vivo And In Vitro Nuclear Magnetic Resonance Imaging And Spectroscopy Of Psychoactive Drugs In Rat Brain, Diana M. Lindquist

Theses and Dissertations

Four psychoactive drugs were studied using various in vivo nuclear magnetic resonance (NMR) techniques. Trifluoperazine (TFP) was given to several normal rats, whose brains were then studied using in vivo fluorine-19 NMR. Three peaks were detected in the in vivo fluorine spectra: one at -62 ppm, which was due to TFP, and two others at -55 and -75 ppm, which are due to unknown metabolites of TFP. Samples of skin, skull, muscle, and brain were obtained from these rats and extracted for in vitro analysis. The metabolites responsible for the in vivo peak at -75 ppm also appeared in the …

Turkish Journal of Medical Sciences

The purpose of this study is to examine the morphological effect which appears in acini and ductus of palatine glands in patients wearing total prostheses. Acini had considerably wide lumens due to de-generation and desquamation in secretory epithelial cells in those who wear prostheses during varying periods. It was observed that, in regions adjacent to the apical membrane in most of the epithelial cells of acini and excretory canals, large vacuoles were formed, whereas in some others, cytoplasm was disarranged due to membrane destruction. Cytoplasmic structures which were encountered in these cells underwent to degeneration and desquamation as well as …


Mannoprotein Adhesin Of Candida Albicansgerm Tubes, Gülhan Vardar-Ünlü Jan 1998

Mannoprotein Adhesin Of Candida Albicansgerm Tubes, Gülhan Vardar-Ünlü

Turkish Journal of Medical Sciences

The production and detection of a mannoprotein adhesin (MPA) of the hyphal-form cells of C. albicans on plastic petri dishes was investigated. Using Concanavalin A-coated latex microspheres, the MPA was detected on the plastic surface on which C. albicans produced germ tubes. The adhesin was extracted using dithiothreitol and iodoacetamide. It did not inhibit the adhesion of the yeast-form C. albicans to buccal epithelial cells (BEC). This suggested that the MPA of the hyphal-form cells on the plastic was different from that on the yeast cells responsible for attachment to the BECs.

A Systematic Evaluation Of Methods To Separate X- And Y- Bearing Sperm, Jacquelyn Irving Jan 1998

A Systematic Evaluation Of Methods To Separate X- And Y- Bearing Sperm, Jacquelyn Irving

Theses: Doctorates and Masters

This project was initiated to determine if was possible to enrich either X- or Y- bearing sperm, and hence to preselect the sex of a child. Two of the possible reasons why couple might want to select the sex of a child are firstly because of a family history of an X-linked recessive genetic disorder, which usually only affect sons, and secondly families who have had several children of one sex. For this study, men with three or more children of the same sex were recruited following the publication of an article in The West Australian newspaper. The percentage of …


Exclusion Mapping Of Polycystic Kidney Disease: A Third Locus, Eoin Thompson Jan 1998

Exclusion Mapping Of Polycystic Kidney Disease: A Third Locus, Eoin Thompson

Theses: Doctorates and Masters

The aim of this research was to perform exclusion on a rare form of hereditary autosomal dominant polycystic kidney disease (ADPKD). To-date, two genes for ADPKD have been identified: PKDI which has been localized to the short arm of chromosome 16 and PKD2 which has been localized to the long arm of chromosome 4. However, a small number of families have been reported that have not shown linkage to either of these two loci, thus suggesting the existence of at least one additional locus (PKD3). Two families that are affected with ADPKD and do not show linkage to PKDI or …
