A test-scale wireless chemical sensor network (WCSN) has been deployed within a controlled Environmental Chamber (EC). The combined signals from the WCSN were used to initiate a controllable response to the detected chemical event. When a particular sensor response pattern was obtained, a purging cycle was initiated. Sensor data were continuously checked against user-defined action limits, to determine if a chemical event had occurred. An acidic contaminant was used to demonstrate the response of the sensor network. Once the acid plume was simultaneously detected by a number of wireless chemical sensor nodes, an automatic response action, which was the purging …

This study with Australian consumers investigated how appealing different health claims combined with particular food carriers were to Australian consumers, and compared the results of a similar study with Dutch consumers. 149 shoppers considered up to 30 different food concepts, rating how ‘attractive’, ‘believable’, and ‘new and different’ they found each concept and their ‘intention to try’. Each variable was significantly related to intention to try (p<0.001) and together explained 56% of the intention score. Claims and carriers independently had a significant effect on ratings of attractiveness and intention to try but, unlike the Dutch study, the carrier was a more important predictor of intention to purchase than the claim. Implications for regulation of health claims for food are discussed.

Changes of molecular dynamics in the α-to-β transition associated with amyloid fibril formation were explored on apo-myoglobin (ApoMb) as a model system. Circular dichroism, neutron and X-ray scattering experiments were performed as a function of temperature on the protein, at different solvent conditions. A significant change in molecular dynamics was observed at the α-to-β transition at about 55 ˚C, indicating a more resilient high temperature β structure phase. A similar effect at approximately the same temperature was observed in holo-myoglobin, associated with partial unfolding and protein aggregation. A study in a wide temperature range between 20 K and 360 K …
M Protein Mediated Plasminogen Binding Is Essential For The Virulence Of An Invasive Streptococcus Pyogenes Isolate, Martina L. Sanderson-Smith, K. Dinkla, J. N. Cole, Amanda J. Cork, P. G. Maamary, Jason D. Mcarthur, G. S. Chhatwal, Mark J. Walker

The human protease plasmin plays a crucial role in the capacity of the group A streptococcus (Streptococus pyogenes; GAS) to initiate invasive disease. The GAS strain NS88.2 was isolated from a case of bacteremia from the Northern Territory of Australia, a region with high rates of GAS invasive disease. Mutagenesis of the NS88.2 plasminogen binding M protein Prp was undertaken to examine the contribution of plasminogen binding and cell surface plasmin acquisition to virulence. The isogenic mutant NS88.2prp was engineered whereby four amino acid residues critical for plasminogen binding were converted to alanine codons in the GAS genome sequence. The …

The alpha-crystallins are members of the small heat shock protein (sHSP) family of molecular chaperones which have evolved to minimize intracellular protein aggregation, however they are also implicated in a number of protein deposition diseases. In this study we have employed novel mass spectrometry techniques to investigate the changes in quaternary structure associated with this switch from chaperone to adjuvant of aggregation. We have replicated the oligomeric rearrangements observed for in vivo disease-related modifications, without altering the protein sequence, by refolding the alpha-crystallins in vitro. This refolding results in a loss of dimeric substructure concomitant with an augmentation of substrate …
Cell Wall-Bound Ultraviolet-Screening Compounds Explain The High Ultraviolet Tolerance Of The Antarctic Moss, Ceratodon Purpureus, L. J. Clarke, Sharon A. Robinson
Cell Wall-Bound Ultraviolet-Screening Compounds Explain The High Ultraviolet Tolerance Of The Antarctic Moss, Ceratodon Purpureus, L. J. Clarke, Sharon A. Robinson
Faculty of Science - Papers (Archive)
Studies of ultraviolet (UV) light-induced DNA damage in three Antarctic moss species have shown Ceratodon purpureus to be the most UV tolerant, despite containing lower concentrations of methanol-soluble UV-screening compounds than the co-occurring Bryum pseudotriquetrum. In this study, alkali extraction of cell wall-bound phenolics, combined with methanol extraction of soluble phenolics, was used to determine whether cell wall-bound UV screens explain the greater UV tolerance of C. purpureus. The combined pool of UV screens was similar in B. pseudotriquetrum and C. purpureus, but whilst B. pseudotriquetrum had almost equal concentrations of MeOH-soluble and alkali-extractable cell wall-bound UV-screening compounds, in C. …

Evaluation of climate model simulations using observed data contributes to the assessment of confidence in model predictions of future climate change. The mid-Holocene represents an opportunity to evaluate model simulations of El Niño–Southern Oscillation (ENSO) in comparison with coral proxy evidence of reduced ENSO amplitude. Quantitative comparisons between coral records and model output have been limited by (1) the use of different measures of ENSO amplitude, (2) possible sampling of natural variability in short records, and (3) uncertainty about the stationarity of the relationship between central Pacific sea surface temperature (SST) variability and ENSO signals at the coral site. We …

This study evaluated the menus and food service experience of inmates in three correctional centres in Sydney (one minimum security, one high security, and one for women). Menus were evaluated against recommended dietary intakes, dietary guidelines and nutrition policy statements. Menus generally provided a well varied selection of foods which met the majority of individual nutritional requirements and dietary guidelines - assuming all food provided was consumed. Focus groups and interviews with 35 inmates explored their attitudes about and experiences of the foodservice provision. Sixteen key themes of concern were identified, including: • Complaints about food quality, lack of choice, …
Allelic Variants Of Streptokinase From Streptococcus Pyogenes Display Functional Differences In Plasminogen Activation., Jason D. Mcarthur, F. C. Mckay, V. Ramachandran, P. Shyam, Amanda J. Cork, Martina L. Sanderson-Smith, J. N. Cole, U. Ringdahl, U. Sjobring, M. Ranson, Mark J. Walker

A common mammalian defence mechanism employed to prevent systemic dissemination of invasive bacteria involves occlusion of local microvasculature and encapsulation of bacteria within fibrin networks. Acquisition of plasmin activity at the bacterial cell surface circumvents this defence mechanism allowing invasive disease initiation. To facilitate this process, S. pyogenes secrete streptokinase, a plasminogen activating protein. Streptokinase polymorphism exhibited by S. pyogenes isolates is well characterised. However, the functional differences displayed by these variants and the biological significance of this variation has not been elucidated. Phylogenetic analysis of ska sequences from 28 S. pyogenes isolates revealed two main sequence clusters (clusters 1 …

Water constitutes the intracellular matrix in which biological molecules interact. Understanding its dynamic state is a main scientific challenge, which continues to provoke controversy after more than 50 years of study. We measured water dynamics in vivo in the cytoplasm of Escherichia coli by using neutron scattering and isotope labelling. Experimental timescales covered motions from pure water to interfacial water, on an atomic length scale. In contrast to the widespread opinion that water is ‘tamed’ by macromolecular confinement, the measurements established that water diffusion within the bacteria is similar to that of pure water at physiological temperature.

There is strong evidence that a diet high in wholegrains is associated with lower BMI, waist circumference and risk of being overweight; that a diet high in wholegrains and legumes can help reduce weight gain; and that significant weight loss is achievable with energy controlled diets that are high in cereals and legumes. There is weak evidence that high intakes of refined grains may cause small increases in waist circumference in women. There is no evidence that low carbohydrate diets that restrict cereal intakes offer long term advantages for sustained weight loss. There is insufficient evidence to make clear conclusions …

We present direct quasielastic neutron scattering measurements, in vivo, of macromolecular dynamics in E. coli. The experiments were performed on a wide range of time-scales, to cover the large panel of internal and self-diffusion motions. Three major internal processes were extracted at physiological temperature: a fast picosecond (ps) process that corresponded to restricted jump diffusion motions, and two slower processes that resulted from reorientational motions occurring in about 40 ps and 90 ps, respectively. The analysis of the fast process revealed that the cellular environment leads to an appreciable increase in internal molecular flexibility and diffusive motion rates compared to …

Serum opacity factor (SOF) is a unique multifunctional virulence determinant expressed at the surface of Streptococcus pyogenes and has been shown to elicit protective immunity against GAS infection in a murine challenge model. SOF consists of two distinct domains with different binding capacities: an N-terminal domain that binds apolipoprotein AI and a C-terminal repeat domain that binds fibronectin and fibrinogen. The capacity of SOF to opacify serum by disrupting the structure of high density lipoproteins may preclude its use as a vaccine antigen in humans. This study generated mutant forms of recombinant SOF with reduced (100-fold) or abrogated opacity factor …

1 Previous studies of Antarctic clonal moss populations using RAPD markers have reported extraordinarily high levels of genetic variation. This has been claimed to reflect somatic mutation, possibly resulting from elevated UV-B radiation. 2 Our study used microsatellite markers to compare the genetic variation present within continental Antarctic, sub-Antarctic and temperate populations of the moss Ceratodon purpureus. 3 In contrast to the RAPD studies, microsatellite data revealed that C. purpureus populations from continental Antarctica display less intra-population genetic diversity than populations from a range of temperate and sub-Antarctic sites. 4 Analysis of Molecular Variation (AMOVA) revealed that populations within the …

Elastic incoherent neutron scattering was used to explore solvent isotope effects on average macromolecular dynamics in vivo. Measurements were performed on living E. coli bacteria containing H2O and D2O, respectively, close to physiological conditions of temperature. Global macromolecular flexibility, expressed as mean square fluctuation (MSF) values, and structural resilience in a free energy potential, expressed as a mean effective force constant, hk0i, were extracted in the two solvent conditions. They referred to the average contribution of all macromolecules inside the cell, mostly dominated by the internal motions of the protein fraction. Flexibility and resilience were both found to be smaller …

The relationships between heat production, alternative oxidase (AOX) pathway flux, AOX protein, and carbohydrates during floral development in Nelumbo nucifera (Gaertn.) were investigated. Three distinct physiological phases were identified: pre-thermogenic, thermogenic, and post-thermogenic. The shift to thermogenic activity was associated with a rapid, 10-fold increase in AOX protein. Similarly, a rapid decrease in AOX protein occurred post-thermogenesis. This synchronicity between AOX protein and thermogenic activity contrasts with other thermogenic plants where AOX protein increases some days prior to heating. AOX protein in thermogenic receptacles was significantly higher than in post-thermogenic and leaf tissues. Stable oxygen isotope measurements confirmed that the …

High Plantar Pressures And Foot Pain: Are They Contributing To Falls In Older Adults?, Karen J. Mickle, Bridget J. Munro, S. R. Lord, Hylton B. Menz, Julie R. Steele
Faculty of Health and Behavioural Sciences - Papers (Archive)
Falls, the leading cause of injuries in older adults, typically occur during ambulation. As such, gait and balance abnormalities are frequently cited as falls risk factors. During normal gait, the foot is the only source of direct contact with the ground and, therefore, it plays a substantial role in maintaining stability and balance. Foot pain has been found to impair balance and gait in women (Leveille, 1998), and has been shown to be falls risk factor in institutionalised elders (Menz, 2006), however it unknown whether foot pain is a risk factor for falling in community-dwelling older adults. As foot pain …

Breast cancer is a prevalent, life-impacting disease. With increasing incidence rates and a growing number of survivors, greater efforts must be directed towards improving the physical functioning and quality of life (QoL) of women living with a diagnosis of breast cancer. Although exercise interventions have been reported to provide these benefits, without the development of adverse events. many impediments to exercise exist (Rogers, 2007). While several psychosocial or physical capacity impediments to exercise have been investigated, a recent study found that a substantial proportion (70.3%) of women living with a breast cancer diagnosis reported experiencing bra discomfort during exercise (Gho, …

Ischaemic preconditioning is a powerful cardioprotective phenomenon. Cardioprotection afforded by (n-3) polyunsaturated fatty acids (PUFA) also suggests preconditioning-like effects. This study examined the effects of dietary fish oil on heart function and injury during myocardial ischemia and reperfusion and interactions between diet and ischemic preconditioning (IP). Male Wistar rats were fed diets containing 10% fat by weight including either 7% fish oil + 3% olive oil (n-3) PUFA); 5% sunflower seed oil + 5% olive oil ((n-6) PUFA); or 7% saturated fat-rich beef tallow + 3% olive oil (SF) for 6 weeks. Isolated perfused hearts subjected to 30min regional ischemia …

Some atypical antipsychotics clinically used to treat schizophrenia induce weight gain by unknown mechanisms. The dorsal vagal complex (DVC) of the brainstem and the endogenous cannabinoid system are implicated in the regulation of appetite signalling and food intake. We investigated whether antipsychotic drugs alter cannabinoid receptor-binding density in the DVC. Female Sprague–Dawley rats were treated with olanzapine, haloperidol, aripiprazole or vehicle for 1 wk (short-term) or 12 wk (chronic). Quantitative autoradiographic methods were employed to investigate the binding density of cannabinoid receptors in the DVC using a highly sensitive Beta Imager. Short-term olanzapine induced a significant 39% decrease in cannabinoid …

Malnutrition is prevalent in elderly hospitalised patients and has been associated with longer lengths of stay (LOS), higher rates of complications and increased hospital costs. Feeding assistance has traditionally been the role of nurses, however with an ageing population and an ever-increasing workload there may not be sufficient time to ensure the nutritional care of all patients. A program in which trained volunteers assist, socialise and feed nutritionally vulnerable patients at lunch on weekdays has been initiated in a major suburban hospital in Sydney. The pilot study reported here aimed to evaluate the lunchtime assistance program in terms of dietary …

The 3 main types of fat in our diet are saturated fat, monounsaturated fat and polyunsaturated fat. Saturated fatty acids do not contain any carbon double bonds, as the fatty acid is fully saturated with hydrogens. Monounsaturated fatty acids, as the name suggests contain fatty acids with one carbon double bond (i.e. mono meaning one) and likewise polyunsaturated fatty acids contain two or more carbon double bonds.

Using a context-based case-control trial, 41 adults with type 2 diabetes mellitus were randomized into four groups to complete dietary assessments (computerized or interviewer administered) at 0, 2 and 8 weeks and food records at 0 and 2 weeks. Repeatability of reported energy, total fat, saturated, polyunsaturated and monounsaturated fatty acids between the computerized and interviewer administered methods were assessed using repeated measures ANOVA. Paired t-tests and Pearson's correlations determined relative validity of the assessments.

The domain of life planning and personal development includes the important techniques of values clarification, strengths identification, goal setting and action planning. In the past two decades practices such as life coaching have grown in popularity (Green, Oades & Grant, 2006). Moreover, in mental health contexts, the recovery movement has challenged the illness and deficit focus (Andresen, Caputi, Oades, 2006; Oades et al, 2005) whilst within the discipline of psychology, the positive psychology movement has questioned the negative focus of clinical psychology (Resnick & Rosenheck, 2006). It is however easier to critique an existing area than the provide suggestions and …

To construct a nutrient database for use with a large population-based cohort study, the Blue Mountains Eye Study, dietary intakes were estimated using the Australian electronic food composition nutrient databases to which values for additional nutrients were added, including folate, vitamin B12, carotenoids and fatty acids. The addition of nutrient data from alternative, overseas, database sources may be useful in relation to the assessment of outcome measures, however the data obtained from these sources need to be interpreted with care, especially in relation to absolute quantities of intake.
