    A huge amount of apple waste is generated from juice, cider and other apple product industries. This waste represents a cost and causes environmental problems. Apple waste is a rich source of polyphenolic compounds, mostly found in the apple peels and cores. Polyphenols are antioxidants with high value that can be extracted from the waste and exploited commercially. Proper methods of waste pasteurisation would allow its preservation and reduce waste degradation. In this study, diluted apple waste was pasteurised using three different technologies: thermal processing (TP), high pressure processing (HPP) and low pressure assisted thermal processing. The effect of processing on the waste native yeasts and moulds, inoculated Saccharomyces cerevisiae yeast and antioxidants were investigated. TP at 60, 80 and 100 °C for 30 min, HPP at 300, 400 and 500 MPa for 10 min and 600 MPa for 20 min, and low pressure assisted thermal processing at 60, 80 and 100 °C with 2 MPa for 30 min were carried out. The total yeasts and moulds initially in the diluted apple waste was about 6.6×101 cfu/g, which was fully inactivated by the three technologies. S. cerevisiae inoculated in the waste was reduced by 5-log or more with all processing methods/conditions. HPP and low pressure assisted thermal processing treatments did not affect the antioxidant activity (DPPH-radical scavenging). However, both TPC and DPPH radical scavenging decreased with TP (p < 0.05). The results of this study can be helpful for designing appropriate conditions to pasteurise fruit industry byproducts for further extraction of high value antioxidants.

  • Bridging the Computational Modelling and EHR standards using openEHR and Semantic Web Technology

    Atalag, Koray; Zivaljevic, Aleksandar; Cooling, Michael; Nickerson, David (2015-10-12)

    Conference poster

    Linking clinical data to computational physiology will enable real-world model validation as well as the possibility of personalised and population level predictive decision support tools. Electronic health records (EHR) embody quantifiable manifestations of genomic and environmental aspects that impact on biological systems when clinical data are structured. However data quality and semantic interoperability remains a major challenge in the world of EHRs. In the computational physiology domain recent attempts to enable semantic interoperability heavily rely on Semantic Web technologies and utilise ontology-based annotations (e.g. RICORDO) but a wealth of useful information and knowledge sits in EHRs where Semantic Web technologies have very limited use. openEHR provides a set of an open engineering specifications that provides a canonical health record architecture and open source tooling to support data collection and integration. Core openEHR specifications have also been adopted by ISO and CEN making it a full international standard which underpins many national programs and has multi-vendor implementations worldwide. Our work describes how to use openEHR to normalise, annotate and link clinical data with biophysical models by using openEHR Archetypes as semantic pointers to underlying clinical concepts in EHR.

  • PUKUmahi!: Kia whai te huarahi tika. NETwork! Roadmap for safe travel: Ensuring health benefits flow on to M??ori

    Neuroendocrine tumours (NET) are complex and variable, making it very difficult for clinicians to determine the best course of treatment. The NETwork project seeks to better understand the epidemiological impact of NETs in New Zealand, and to better characterise the disease to help inform oncologists how to treat it. The estimated incidence rate of patients with NETs in New Zealand is approximately 200 patients per year, however the impact among M??ori is not yet known. M??ori are disproportionately burdened by cancers of the lungs, stomach, and pancreas, so it is tempting to speculate that NET incidence among M??ori could also be high. It is essential that M??ori are involved in the study in order to get an accurate indication of the impact of this cancer in New Zealand, what genes are driving the cancers, and how each can be treated. The multi-faceted NETwork project combines epidemiological analysis and deep genome sequencing of retrospective and prospective NET tissues. Under the guidelines set out in Te Ara Tika, the design of this research project is mainstream, but is likely to involve M??ori participants and have direct relevance to M??ori. Despite being neither M??ori-centred nor Kaupapa M??ori in our approach, the NETwork team are dedicated to honouring the Treaty of Waitangi principles of partnership, participation, and protection. Mindful of the past transgressions involving the use of tissues and genetic information obtained from indigenous populations here in New Zealand and overseas, the NETwork group are keen not to repeat these errors themselves, nor facilitate the opportunity for others to do so. Following ongoing consultation with Te Mata Ira, Maui Hudson, Dr Helen Wihongi, and Associate Professor Papaarangi Reid, we have established a ???roadmap for safe travel??? to guide all aspects of the multi-faceted project. The framework has three key principles (kawa) underpinning its Governance structure, and three core cultural protocols (tikanga) to be incorporated into the implementation strategies. Adhering to these kawa and tikanga should facilitate the establishment and maintenance of relationships with key stakeholders; a vital aspect to the project. The roadmap for safe travel is still in its early stages of development, and consultation is ongoing. Nevertheless, the NETwork team have a strong platform from which to further develop their project. Although the presented framework is specific to the NETwork project, it could easily be adjusted and utilised for other clinical and biomedical projects.

    Conference poster

    Background: The prevalence of myopia continues to grow, and there are now a number of optical treatment options available to clinicians. However real world clinical data on their effectiveness is sparse. To promote anti-myopia treatments, a specialist Myopia Control Clinic (MCC) opened as a referral clinic at The University of Auckland, New Zealand in 2010, and this is the first comprehensive audit of the clinical outcomes. Case Series: We present a retrospective case series of 110 patients (aged 4 ??? 33 years, mean: 12.13 ?? 4.58 years, 57% female) who attended the MCC between 2010 and 2014. Of these, 56 underwent orthokeratology (OK), 32 wore dual focus soft contact lenses (DFCL), and 22 received advice only. Baseline myopia, vitreous and axial eye length, previous myopia progression, age, number of myopic parents, and gender were not different between OK and DFCL groups at baseline. However, the advice group were older (p = 0.037) and had less previous myopic progression (p = 0.001). Mean follow-up time was 1.30 ?? 0.88 and 1.33 ?? 0.80 years in OK and SCL groups respectively (p = 0.989). There was a significant reduction in the annualised myopia progression in both treatment groups (OK: -1.17 ?? 0.55 to -0.09 ?? 017D/yr, p < 0.001, DFCL: -1.15 ?? 0.46 to -0.10 ?? 0.23D/yr, p < 0.001). There was no difference between OK and DFCL treatment efficacy (p = 0.763), nor in axial or vitreous chamber length changes following treatment (p = 0.184). Only one adverse event was reported over the 4 year period. Conclusions: Contact lenses, whether OK or DFCL, are an effective strategy for targeting myopia progression in children. As there was no difference in the efficacy of the two methods, there are very few barriers in terms of upskilling, chair time, or capital expenditure, for any practitioner to be actively promoting myopia control treatments to at risk groups.

  • Do you see what I see? - Surveillance and response

    Patel, Reena; Dixon, Robyn; Webster, Craig (2015-07-06)

    Conference poster

    Introduction: Early warning scoring systems and rapid response teams are important strategies to improve the detection of patient deterioration in hospitals. Initiation of an appropriate response relies on nurses recognising changes in patient condition and alerting the required emergency assistance team. Study Objective: To determine the level of concordance between the nurse???s assessment and that of the emergency team, based on early warning scores (EWS). Methods: An audit of data collected between June 2011 and May 2013 was undertaken and 2780 instances were reviewed in order to determine the degree of concordance on EWS scores between nurses initiating calls and those assigned by the emergency response team. Results: 881 instances lack of concordance was identified. In the majority of instances, the nurse overestimated the severity of the patient???s condition when compared to the emergency response team???s score. Conclusion: Such lack of concordance is problematic given that failure to activate an emergency response when required has obvious implications for patient safety while inappropriate referral to emergency response teams can result in inefficient use of resources.

  • Reverse Mentoring: Benefits and Barriers

    Ross, M; Dunham, Annette (2015)

    Conference poster
    The University of Auckland Library

    Background: Current research suggests that the modern workforce is comprised of a substantial proportion of ageing employees, in addition to an influx of young, first-time workers. This diverse and multigenerational workforce provides organisations an interesting challenge, in retaining engaged and productive employees, and ensuring relevant training and development. One specific management practice is reverse mentoring. Reverse mentoring is a unique form of mentoring, whereby the traditional roles of mentor and mentee are reversed. It involves a junior employee (in age/status) mentoring a senior employee. The junior employee is able to share their recent generational learnings and perspective with a senior organisational member, who gains insight into recent trends and technologies. Whilst there appear to be many benefits from this relationship, including increased communication and understanding; leadership development; and upskilling in relevant trends, there may also be some barriers to the success of the relationship. Barriers may include a resistance to the shift in power hierarchy and challenges with changing the traditional learning pedagogy of older teacher and younger learner. Aim: Reverse mentoring is a reasonably modern concept, and as such, empirical research on this practice is relatively new. This research aims to explore any benefits and barriers experienced in a reverse mentoring relationship. Method: Participants in this study will be recruited from a Melbourne hospital, who currently run a formal reverse mentoring relationship program. Approximately 16 individuals (8 mentors and 8 mentees), will be invited to participate. The proposed study uses a qualitative method of data collection, through semi-structured interviews. Interviews will be recorded, and responses will be transcribed, with thematic analysis used to identify common themes. Thematic analysis allows the common themes and experiences of mentors and mentees, to tell an overall story of the data. Conclusion: The proposed study???s findings contribute to a currently small base of research on reverse mentoring. It is hoped that the research will help (i) inform future quantitative research on reverse mentoring and (ii) inform organisational strategies that will help employees engage in reverse mentoring relationships in ways that effectively support their training and development.

    As a main source of greenhouse gases urban areas play an important role in the global carbon cycle. To assess the potential role of urban vegetation in mitigating carbon emissions we need information on the magnitude of biogenic CO2 emissions and its driving factors. We examined how urban land use types (urban forest, parklands, sportsfields) vary in their soil CO2 efflux.We measured soil CO2 efflux and its isotopic signature, soil temperature and soil moisture over a complete growing season in Auckland, New Zealand. Soil physical and chemical properties and vegetation characteristics were also measured. Mean soil CO2 efflux ranged from 4.15 to 12 molm 2 s 1.We did not find significant differences in soil CO2 efflux among land cover types due to high spatial variability in soil CO2 efflux among plots. Soil (soil carbon and nitrogen density, texture, soil carbon:nitrogen ratio) and vegetation characteristics (basal area, litter carbon density, grass biomass) were not significantly correlated with soil CO2 efflux. We found a distinct seasonal pattern with significantly higher soil CO2 efflux in autumn (Apr/May) and spring (Oct). In urban forests and sportsfields over 80% of the temporal variation was explained by soil temperature and soil water content. The 13C signature of CO2 respired from parklands and sportsfields (-20 permil - -25 permil) were more positive compared to forest plots (-29 permil) indicating that parkland and sportsfields had a considerable proportion of C4 grasses. Despite the large intra-urban variability, our results compare to values reported from other, often climatically different cities, supporting the hypothesis of homogenization across urban areas as a result of human management practices.

  • Forbidden crystals: Penrose tiling with molecules

    Since the first discovery of quasicrystals by mathematicians in the 1960s, quasicrystalline patterns which possess unusual symmetric orders have become an issue among mathematicians. Observation of 5-fold crystal symmetry in metal alloys in 1984 has attracted other scientists. Penrose tiling is the simplest quasicrystal comprised of only pentagon motifs. Although quasicrystals have been observed in alloys and soft matter states (polymers, colloids), no one has yet successfully generated full molecular quasicrystals. Only small pieces of molecular Penrose tiling have been reported. We are working on this challenge by using molecules with 5-fold symmetry as molecular ???tiles??? to create 2-dimensional molecular Penrose tilings. Alignment of the tiles is the key to creating the quasicrystalline pattern. Possible candidates as tiles which must be synthetically accessible are croconate and its derivatives, macrocycles such as campestarene and supramolecules such as cucurbituril. The techniques of coordination and supramolecular chemistry will direct the ordering of the tiles. After deposition of the synthesised tiles on substrates, surface imaging (STM and AFM) and analytical techniques (XPS, LEED, GI-SAXS) will be used to investigate the resulting films.
