Fibronectin binding protein F1 (Sfb1) of Streptococcus pyogenes (group A streptococcus [GAS]) is a well-characterized adhesin that has been shown to induce protection in mice against a lethal intranasal GAS challenge after intranasal immunization with cholera toxin B subunit (CTB) as adjuvant. With a murine skin infection model, we have shown that Sfb1/CTB vaccination neither elicits opsonizing antibodies nor prevents systemic bacterial growth and dissemination to internal organs after a subcutaneous GAS challenge. These results indicate that an Sfb1-based vaccine should be complemented with additional protective antigens in order to be used in areas such as the tropical north ...


Two Distinct Genotypes Of Prtf2, Encoding A Fibronectin Binding Protein, And The Evolution Of The Gene Family In Streptococcus Pyogenes, V. Ramachandran, Jason D. Mcarthur, C. E. Behm, C. Gutzeit, M. Dowton, P. K. Fagan, R. Towers, B. J. Currie, K. S. Sriprakash, Mark J. Walker Nov 2004

The group A Streptococcus (GAS) is an important pathogen responsible for a wide range of human diseases. Fibronectin binding proteins (FBPs) play important role in promoting GAS adherence and invasion of host cells. The gene prtF2 encodes a FBP and is contained in approximately 60% of GAS strains. In the present study we have examined 51 prtF2-positive GAS strains isolated from the Northern Territory of Australia and describe two genotypes of prtF2, which are mutually exclusive. Both genotypes have been previously identified in the literature as pfbp and fbaB. We show these genotypes map to the same chromosomal location within ...


Austrochlamys Heardensis (Fleming, 1957) (Bivalvia: Pectinidae) From Central Kerguelen Plateau, Indian Ocean: Palaeontology And Possible Tectonic Significance, P. G. Quilty, C. V. Murray-Wallace, J. M. Whitehead Sep 2004

Austrochlamys Heardensis (Fleming, 1957) (Bivalvia: Pectinidae) From Central Kerguelen Plateau, Indian Ocean: Palaeontology And Possible Tectonic Significance, P. G. Quilty, C. V. Murray-Wallace, J. M. Whitehead

Austrochlamys heardensis (Fleming) is recorded from a boulder of Late Pliocene (3.62–2.5 Ma) volcaniclastic sandstone dredged 70 km east-north-east of Heard Island, the third record of the species. The collection is much larger than the original described by Fleming and includes left valves which are described for the first time. The species is compared with A. anderssoni (Hennig) from Cockburn Island and ‘Chlamys’ mawsoni Fletcher from Îles Kerguelen. The source rock accumulated in fully marine, highly current-affected conditions. The collection is dominated by right valves, possibly because left valves are more susceptible to breakage and the effects ...


Australian Backyard Gardens And The Journey Of Migration, Lesley M. Head, Pat Muir, E. Hampel Jul 2004

Australian Backyard Gardens And The Journey Of Migration, Lesley M. Head, Pat Muir, E. Hampel

Faculty of Science - Papers (Archive)

Gardens have been an important site of environmental engagement in Australia since the British colonization. They are places where immigrant people and plants carry on traditions from their homelands, and work out an accommodation with new social and biophysical environments. We examine the backyard gardens of three contemporary migrant groups in suburban Australia, Macedonian, Vietnamese and British-born, and a fourth group of first generation Australians with both parents born overseas. There is strong emphasis on the production of vegetables in Macedonian backyards, and herbs and fruit in Vietnamese backyards. British backyards were more diverse, some focusing on non-native ornamental flowers ...


Comparison Of Solvent Regimes For The Extraction Of Photosynthetic Pigments From Leaves Of Higher Plants, J. L. Dunn, J. D. Turnbull, Sharon A. Robinson Apr 2004

Comparison Of Solvent Regimes For The Extraction Of Photosynthetic Pigments From Leaves Of Higher Plants, J. L. Dunn, J. D. Turnbull, Sharon A. Robinson

Faculty of Science - Papers (Archive)

The relative efficiency of methanol- and acetone-based solvents for the extraction of pigments from photosynthetic tissues of plant was compared, together with the advantages of multiple versus single extractions. The two commonly employed triple acetone extractions (100:80:80% and 85:100:100%) performed comparably for most pigments and for all plant species tested. Single extractions with either 96% methanol or 85% acetone failed to extract the more hydrophobic pigments, especially ?-carotene. We conclude that multiple extractions that combine pure and aqueous (80–85%) acetone are preferable for extraction of the full range of pigments. These results suggest that previous ...


Nativeness, Invasiveness And Nation In Australian Plants, Lesley M. Head, Pat Muir Apr 2004

Nativeness, Invasiveness And Nation In Australian Plants, Lesley M. Head, Pat Muir

Faculty of Science - Papers (Archive)

The conceptualization of alien invasive species conflates two axes of variability that have become unhelpfully blurred. The nativeness/alienness axis refers to the presumed belonging of a species in ecological or social space. Invasiveness refers to the behavior of the species in question, particularly in relation to other species. The overlay of nation introduces further variability. Teasing these axes apart is important for more effective environmental management. We examine these concepts using two influential forms of ecological knowledge: the biogeographical and ecological literature and the vernacular experiences of suburban backyarders. Three case studes, the invasive native Pittosporum undulatum and two ...


National Inquiry On Bushfire Mitigation And Management, S. Ellis, P. Kanowski, R. J. Whelan Mar 2004

National Inquiry On Bushfire Mitigation And Management, S. Ellis, P. Kanowski, R. J. Whelan

Faculty of Science - Papers (Archive)

Bushfires are an inherent part of the Australian environment. We cannot prevent them, but we can minimise the risks they pose to life, property and infrastructure, production systems, and the environment. Australia has a large and very capable force of volunteer and career firefighters, advanced firefighting technologies, and significant firefighting resources. But the geographical scale of our country, the large and expanding rural–urban interface, and the potential for rapid bushfire development and spread under adverse weather conditions mean that individual Australians cannot rely solely on fire agencies to protect their lives and property from bushfires. Bushfires have a fundamental ...


Trace Gas Emissions From Biomass Burning Inferred From Aerosol Optical Depth, Clare Paton-Walsh, N. B. Jones, Stephen R. Wilson, A. Meier, N. Deutscher, D. W. Griffith, R. Mitchell, S. Campbell Mar 2004

Trace Gas Emissions From Biomass Burning Inferred From Aerosol Optical Depth, Clare Paton-Walsh, N. B. Jones, Stephen R. Wilson, A. Meier, N. Deutscher, D. W. Griffith, R. Mitchell, S. Campbell

Faculty of Science - Papers (Archive)

We have observed strong correlations between simultaneous and co-located measurements of aerosol optical depth and column amounts of carbon monoxide, hydrogen cyanide, formaldehyde and ammonia in bushfire smoke plumes over SE Australia during the Austral summers of 2001/2002 and 2002/2003. We show how satellite-derived aerosol optical depth maps may be used in conjunction with these correlations to determine the total amounts of these gases present in a fire-affected region. This provides the basis of a method for estimating total emissions of trace gases from biomass burning episodes using visible radiances measured by satellite.


Food Fears: A National Survey On The Attitudes Of Australian Adults About The Safety And Quality Of Food, P. G. Williams, E. Stirling, N. Keynes Jan 2004

Food Fears: A National Survey On The Attitudes Of Australian Adults About The Safety And Quality Of Food, P. G. Williams, E. Stirling, N. Keynes

Faculty of Health and Behavioural Sciences - Papers (Archive)

A national telephone survey of a representative sample of 1200 Australian adults was conducted in March 2002 in order to identify the factors of greatest concern to consumers in relation to the safety and quality of food, to measure recent trends in views about hazards in the food supply, to explore beliefs about the safety of additives and to discover whether consumers use food labels to check for ingredients of concern. Forty five percent of Australians responded that they were more concerned about the safety and quality of food than they were five years previously, while only 5% were less ...

Protecting Group Effects On The Efficiency Of The Ruthenium-Catalyzed Alder-Ene Reaction, Joseph Hartley, Stephen G. Pyne

Faculty of Science - Papers (Archive)

The efficiency of the ruthenium-catalysed Alder-ene reaction of hydroxy alkenes depends heavily on the nature of the O-protecting groups employed as well as the length of the carbon spacer between the hydroxy and alkene group.


Negotiating Nature: Collaboration And Conflict Between Aboriginal And Conservation Interests In New South Wales, Australia, Michael Adams Jan 2004

Negotiating Nature: Collaboration And Conflict Between Aboriginal And Conservation Interests In New South Wales, Australia, Michael Adams

Faculty of Science - Papers (Archive)

Faced with the paradox of a large global increase in conservation reserves and a simultaneous global decrease in actual effective protection for biodiversity, conservation scientists and policymakers are questioning established conservation theory and practice. I argue that the fundamental premises, the foundational myths, for Western-style conservation also need to be questioned. The statistics on Indigenous land claims, and conservation reserves, in Australia and more specifically the state of New South Wales (NSW), reveal a landscape of policy failure in both arenas. Focusing on Australia, I use spatial analysis and policy histories to demonstrate converging trajectories of land use priorities for ...


Molecular Dynamics Simulations Of Peptides Containing An Unnatural Amino Acid: Dimerization, Folding, And Protein Binding, Haibo Yu, Xavier Daura, Wilfred Van Gunsteren Jan 2004

Molecular Dynamics Simulations Of Peptides Containing An Unnatural Amino Acid: Dimerization, Folding, And Protein Binding, Haibo Yu, Xavier Daura, Wilfred Van Gunsteren

Faculty of Science - Papers (Archive)

We have performed molecular dynamics (MD) simulations to study the dimerization, folding, and binding to a protein of peptides containing an unnatural amino acid. NMR studies have shown that the substitution of one residue in a tripeptide β-strand by the unnatural amino acid Hao (5-HO2CCONH-2-MeO-C6H3-CO-NHNH2) modifies the conformational flexibility of the β-strand and the hydrogen-bonding properties of its two edges: The number of hydrogen-bond donors and acceptors increases at one edge, whereas at the other, they are sterically hindered. In simulations in chloroform, the Hao-containing peptide 9 (i-PrCO-Phe-Hao-Val-NHBu) forms a β-sheet–like hydrogen-bonded dimer, in good agreement with the available ...

We investigated the performance of the recently developed SPC/L model for liquid water, as a pure liquid, in binary mixtures with DMSO, and as a solvent model in a peptide folding simulation. Additionally, in order to test the compatibility with the GROMOS biomolecular force field, free energies of hydration of a set of representative compounds were computed. The results are compared to those for the well established SPC water model, which is generally used as a solvent model in conjunction with the GROMOS force field already for more than two decades. It turns out that as a pure liquid ...

Photosynthesis In Silico. Overcoming The Challenges Of Photosynthesis Education Using A Multimedia Cd-Rom, A. W. Russell, G. M.A. Netherwood, Sharon A. Robinson

Faculty of Science - Papers (Archive)

Photosynthesis is a central topic in biology education. It remains one of the most challenging, largely because of a) its conceptual difficulty, leading to lack of interest and misconceptions among students; b) the difficulties students have in visualising the process, or relating it to things they can see, especially when the topic is presented purely as a molecular process; and c) limitations to the practical demonstration of photosynthesis because equipment is either cheap, unreliable and antiquated or prohibitively expensive. In response, we have combined expertise in photosynthesis research and education, and in graphic design, to produce an interactive, multimedia package ...


Landscape Management: Is It The Future?, R. J. Whelan Jan 2004

Landscape Management: Is It The Future?, R. J. Whelan

Faculty of Science - Papers (Archive)

As a Keynote Address at the 2004 Nature Conservation Council Conference, Bushfire in a Changing Environment - New Directions in Management, this paper argues that the landscape is a template with biodiversity assets, and human assets and bushfires overlaid. Two case studies, the Greater Glider and Eastern Bristlebird, are used to illustrate how the impact of bushfire on a species is contingent on it is distributed in the landscape, relative to the locations of its remnant habitat. Mitigation of bushfire effects, using fuel-reduction programs, is a process that also needs to be considered at a landscape scale, and has the potential ...


Processes Controlling Metal Transport And Retention As Metal-Contaminated Groundwaters Efflux Through Estuarine Sediments, Stuart L. Simpson, Edward J. Maher, Dianne F. Jolley Jan 2004

Processes Controlling Metal Transport And Retention As Metal-Contaminated Groundwaters Efflux Through Estuarine Sediments, Stuart L. Simpson, Edward J. Maher, Dianne F. Jolley

Faculty of Science - Papers (Archive)

Factors affecting the transport and retention of Cd, Cr, Cu, Ni, Pb and Zn in acidic groundwaters as they pass through estuarine sediments were investigated using column experiments. Acidic groundwaters caused the rapid dissolution of iron sulfide (AVS) and other iron and manganese phases from sediments that are important for metal binding and buffering. Metal breakthrough to overlying water occurred in the order of Ni>Zn>Cd>>Cu>>Cr/Pb. Metal transport increased as the sediment permeability increased, reflecting the low resistance to flow caused by larger sand-sized particles and the decreased abundance of metal adsorption sites on these materials ...

Faculty of Science - Papers (Archive)

A new pentacyclic Stemona alkaloid, stemocurtisinol (3), with a pyrido[1,2-a]azepine A,B-ring system, and the known pyrrolo[1,2-a]azepine alkaloid oxyprotostemonine (4) have been isolated from a root extract of S. curtisii. The structure and relative stereochemistry of stemocurtisinol was determined by spectral data interpretation and X-ray crystallography. This compound is a diastereoisomer of oxystemokerrin and has the opposite configuration at C-4 and C-19. The individual alkaloid components showed significant larvicidal activity (IC50 4−39 ppm) on mosquito larvae (Anopheles minimus HO).

Using A Taxonomy Of Errors As A Conceptual Framework For Differences In Patterns Of Use For Casual And Novice Users, Jocelyn R. Harper, Peter Caputi, Rohan Jayasuriya, Shae-Leigh C. Vella, P. Hyland Jan 2004

Using A Taxonomy Of Errors As A Conceptual Framework For Differences In Patterns Of Use For Casual And Novice Users, Jocelyn R. Harper, Peter Caputi, Rohan Jayasuriya, Shae-Leigh C. Vella, P. Hyland

Faculty of Health and Behavioural Sciences - Papers (Archive)

A taxonomy of errors was applied in a recent study of casual and novice users of a statistical analysis software. The taxonomy was found to be useful and several extensions to the taxonomy were proposed. The aim of this study is to confirm the theoretical validity of the proposed extensions and the usefulness of the taxonomy in describing the patterns of human-computer interaction and predicting changes in use patterns with learning.


Individual Differences In Anticipated Emotions, Desires And Intentions In Approaching A Computer Task, Jocelyn R. Harper, Peter Caputi, Rohan Jayasuriya Jan 2004

Individual Differences In Anticipated Emotions, Desires And Intentions In Approaching A Computer Task, Jocelyn R. Harper, Peter Caputi, Rohan Jayasuriya

Faculty of Health and Behavioural Sciences - Papers (Archive)

Research on user training has drawn on psychological theory to understand individual differences effects. An extension of the Model of Goal-directed Behaviour (MGB) was used to test the role of Personality variables, Computer self-efficacy and Computer anxiety as antecedents of anticipated emotions, goal desires and intentions. Positive anticipated emotions were demonstrated to intervene in the relation between Computer self efficacy and goal desires.

Objective To develop a method to monitor trends in the cost of the Illawarra Healthy Food Basket (IHFB) and report trends from 2000 to 2003.

Design Detailed instructions for the method of pricing the IHFB were developed and tested. The price of the IHFB was collected each year in September at a major supermarket, green grocer and butcher in five Illawarra suburbs, representing a range of socio-economic locations. Data on welfare payments available to the reference family, assuming all members were unemployed, were collected from staff of Centrelink.

Main outcome measures The average weekly cost of the IHFB, the Illawarra ...


Diet And Metabolic Syndrome: Where Does Resistant Starch Fit In?, Linda C. Tapsell Jan 2004

Diet And Metabolic Syndrome: Where Does Resistant Starch Fit In?, Linda C. Tapsell

Faculty of Health and Behavioural Sciences - Papers (Archive)

Metabolic syndrome is a term linking the clinical profiles of some of the world’s major health problems today: obesity, heart disease and diabetes. It is predicated on dietary patterns, and particularly on the delivery of fuel. The effects may be seen first in the development of abdominal obesity and insulin resistance leading to type 2 diabetes mellitus and coronary heart disease. This review examines the role resistant starch might play in the prevention and management of these conditions. Beginning with a definition of resistant starch, a critical review of the scientific literature is presented. Current knowledge suggests that resistant ...


An Exploratory Study Of Older Adults' Perceptions Of Dtca For Prescription Medications, Sandra C. Jones, Judy Mullan Jan 2004

An Exploratory Study Of Older Adults' Perceptions Of Dtca For Prescription Medications, Sandra C. Jones, Judy Mullan

Faculty of Health and Behavioural Sciences - Papers (Archive)

There are many arguments for and against Direct-To-Consumer-Advertising (DTCA) and their impact on the consumer. A study involving 97 older consumers was carried out to investigate their perceptions about long or short versions of written DTCA for arthritis or diabetes medication. The results indicate that even though the ads may improve doctor-patient discussion about medications, they would not necessarily empower them to make decisions. Some of the consumers also believed that DTCA might cause people to ask for inappropriate medicines, become confused and possibly stop seeking medical advice.


An Exploratory Study On The Effect Of Positive (Warmth Appeal) And Negative (Guilt Appeal) Print Imagery On Donation Behaviour In Animal Welfare, M. Haynes, Jennifer Thornton, Sandra C. Jones Jan 2004

An Exploratory Study On The Effect Of Positive (Warmth Appeal) And Negative (Guilt Appeal) Print Imagery On Donation Behaviour In Animal Welfare, M. Haynes, Jennifer Thornton, Sandra C. Jones

Faculty of Health and Behavioural Sciences - Papers (Archive)

Very few studies in social marketing empirically compare the effectiveness of positive and negative appeals. This study examines the effect of positive (warmth appeal) and negative (guilt appeal) print imagery on donation behaviour to an animal welfare organisation. A quasiexperimental design was used to test the appeals, using a convenience sample of 282 university students, with each experimental group being exposed to only one type of appeal. The results indicated that negative imagery which evoked guilt was more effective than positive imagery which evoked warmth, on intention to donate money and time to the animal welfare organisation.


The Influence Of Magazine Advertising On Parents' Nutrition Ratings Of Food Products For Children, Christina Hoang, Sandra C. Jones, Jennifer Thornton Jan 2004

The Influence Of Magazine Advertising On Parents' Nutrition Ratings Of Food Products For Children, Christina Hoang, Sandra C. Jones, Jennifer Thornton

Faculty of Health and Behavioural Sciences - Papers (Archive)

Childhood obesity currently affects approximately 22 million children under the age of five worldwide (Rochinni, 2002) and its increasing prevalence in developed nations makes it one of the most common nutritional problems among children (Sorof and Stephen, 2002). A study was conducted to investigate parents’ health-related perceptions for a series of magazine advertisements for commonly advertised and popular children’s food products. The study revealed that confusion exists among parents and this was most evident in relation to the energy content of food products. Parents are important due to the instrumental role they play in their child’s nutrition - both ...


The Impact Of Different Types Of Incentives On Re-Enrolment Into Health Management Programs, Sandra C. Jones, Christina Hoang Jan 2004

The Impact Of Different Types Of Incentives On Re-Enrolment Into Health Management Programs, Sandra C. Jones, Christina Hoang

Faculty of Health and Behavioural Sciences - Papers (Archive)

The Australian Health Management Group (AHMG) offers disease- and risk-management programs for members, aimed at improving health status and reducing health care costs. As an incentive to re-enrol, members are posted a small gift upon receipt of their completed enrolment form. The purpose of the present study was to determine whether the provision of an incentive has a measurable effect on re-enrolment rates. Members were allocated to one of three conditions: “gift”; “competition”; or “no incentive”. We found that the provision of an incentive resulted in an increase in re-enrolment rates, with little difference between the “competition” and “gift” conditions ...


What Can Change Blindness Tell Us About The Visual Processing Of Complex Objects?, Simone Keane, Stephen A. Palmisano Jan 2004

What Can Change Blindness Tell Us About The Visual Processing Of Complex Objects?, Simone Keane, Stephen A. Palmisano

Faculty of Health and Behavioural Sciences - Papers (Archive)

Processing visual information about objects in our environment is an essential and widely used skill. However, recent research in change blindness suggests that humans are remarkably poor at detecting certain types of changes to objects. In particular, changes to the configuration of an object's parts are detected quicker and more accurately than changes to the shape of the parts or a switching of parts. The implication of this finding is that information regarding the layout or configuration of an object is better encoded than finer details, like part shape. The aim of the current study was to determine whether ...
