  • The STn-SNc hyperdirect pathway modulates dopaminergic neuron activity by inhibiting GABAergic inputs from the SNr via endocannabinoids

    The hyperdirect pathway of the basal ganglia circuitry terminates with a glutamatergic projection from the Subthalamic Nucleus (STN) to the Substantia Nigra pars compacta (SNc). We recently showed that glutamate released in the SNc drives endocannabinoid production in dopaminergic neurons, which in turn inhibits GABAergic transmission in that region. The present study investigated the potential role of STN glutamatergic projections of the hyperdirect pathway in this novel endocannabinoid modulatory mechanism. Whole-cell patch-clamp recordings were made from SNc dopaminergic neurons in horizontal brain slices (rat) containing STN, SNc and Substantia Nigra pars reticulata (SNr) regions. Either electrical (bi-polar electrode) or pharmacological (local carbachol application) stimulation of the STN was performed to evoke selective glutamate release from terminals in the SNc. GABAergic inputs to the SNc from the SNr were electrically stimulated to evoke inhibitory post-synaptic currents (eIPSCs). Single-pulse electrical stimulation of the STN caused transient (< 1 sec) attenuation of GABAergic eIPSCs amplitudes recorded from dopaminergic neurons (to 73% of control). The eIPSC attenuation was prevented by block of either cannabinoid CB1 receptors with rimonabant (3 µM) or metabotropic glutamate mGluR1 receptors with CPCCOEt (100 µM). Pharmacological activation of STN neurons by rapid local perfusion of muscarinic agonist carbachol (100 µM, 10 s) caused a similar attenuation of eIPSC amplitude. These findings show that glutamate release from STN terminals in the SNc modulates GABAergic transmission through endocannabinoid signalling – a previously undescribed function of the hyperdirect pathway.

    The University of Auckland Library

    Although the value of DNA profiles found at a crime scene is indisputable, there is increasing importance in identifying the cellular source of the DNA as well as the identity of the person to whom the profile belongs. Knowledge regarding the cellular source from which the DNA profile originates increases the evidential value of the sample. Our research involves investigation of protein candidates in order to find an epithelial cell type-specific protein that will enable differentiation of vaginal, buccal and skin cells in forensic samples. We have used several methods including histochemical stains, western analysis and immunohistochemistry to investigate candidate proteins known to be present in various types of epithelial cells. Our most current results from these studies will be presented here.

    HI-SEAS HI-SEAS (Hawaii Space Exploration Analog and Simulation, www.hi-seas.org) is a habitat on an isolated Mars-like site on the Mauna Loa side of the saddle area on the Big Island of Hawaii at approximately 8200 feet above sea level. HI-SEAS is unique, in addition to its setting in a distinctive analog environment, as: - we select the crew to meet our research needs (in contrast, at serendipitous analogs, such as Antarctic stations, crew selection criteria are not controlled by researchers); - the conditions (habitat, mission, communications, etc.) are explicitly designed to be similar to those of a planetary exploration mission; - the site is accessible year round, allowing longer-duration isolated and confined environment studies than at other locations; - the Mars-like environment offers the potential for analog tasks, such as geological field work by human explorers and/or robots. The ability to select crew members to meet research needs and isolate them in a managed simulation performing under specific mission profiles makes HI-SEAS ideal for detailed studies in space-flight crew dynamics, behaviors, roles and performance, especially for long-duration missions. MISSIONS TO DATE As of February 2016, there have been three missions completed at HI-SEAS, two of four months in length, and one of eight months. The fourth mission, which is twelve months long, is currently under way, and will end in August 2016. UPCOMING MISSIONS The next cycle of missions will see the research focus at HI-SEAS shift from crew cohesion and performance to crew composition. We expect the first of three eight-month missions to start in late 2016. CURRENT RESEARCH The current research projects being carried out at HI-SEAS focus on crew cohesion, function and performance. Preliminary results from each of these projects are being presented in detail by the co-authors separately at this meeting. This presentation will provide an overview of the research conducted to date, and the plans for the future. OPPORTUNISTIC RESEARCH In order to maximize research return, and to provide HI-SEAS crews with a realistic workload, we welcome proposals for opportunistic research to be carried out during HI-SEAS missions. Proposed projects must a) advance human space exploration by addressing NASA’s needs and requirements; b) require a long-duration analog for desired research outcomes; and c) not confound the primary research. If you are interested in submitting an opportunistic research proposal, please contact the first author.

    Conference poster
    The University of Auckland Library

    Branching is a fundamental process affecting plant form and is a source of much of the wide variety of plant architecture seen in nature. Our aim is to understand the function of genes involved in branching using petunia as a model system. This research involves the study of the decreased apical dominance (dad) mutants in petunia, which have increased basal branching compared with wild type. It also involves the investigation of genes known to affect branching in other plant species to discover their effects in petunia. One of these genes, MAX2, was identified from an increased branching mutant in Arabidopsis, and its effects in petunia are being investigated by misexpression of the petunia orthologue. Previous grafting experiments using the dad mutants in petunia have shown that a graft-transmissible signal is involved in causing the increased branching phenotype. Hormones are graft-transmissible chemicals and variation in their levels play important roles in the control of apical dominance, one of the most studied controls in lateral branching. Auxin and cytokinin levels in dad mutant and wild type plants were investigated, but the levels of these hormones were not consistent with them being the graft-transmissible signal modified by the DAD genes. In order to investigate the relationships between the DAD genes, the branching phenotypes of the single and double dad mutants were characterised and analysed. Grafting experiments to investigate the interactions between the DAD genes in controlling the branching signal were also undertaken. This work has revealed interactions between the DAD genes and provided evidence for the order of action of these genes.

    Snakin-1 is a 63 residue antimicrobial protein originally isolated from potato (Solanum tuberosum).1 It is active against a number of bacterial and fungal phytopathogens such as Clavibacter michiganensis, Pseudomonas syringae and Fusarium solani. Snakin-1 is a member of the GASA (gibberellic acid stimulated in Arabidopsis)/snakin family and the mature protein consists of a GASA domain incorporating six intramolecular disulfide bonds.2 The amino acid sequences of these proteins do not correspond to any known structural motifs. GASA/snakin proteins are found in a variety of plant species and appear to be involved in a range of functions including cell elongation and cell division.2 Their expression profiles support these roles and are commonly linked to development.2 It has also been speculated that the 12 conserved cysteines in these proteins perform a role in redox regulation.2 We have recently completed the total chemical synthesis of native Snakin-1 and showed that its antimicrobial activity is comparable to that of the naturally occurring protein.3 In an attempt to understand how this small protein functions we have determined its threedimensional structure by X-ray crystallography using a quasi-racemic protein system.4 Phase information for structural determination was obtained by radiation-damage induced phasing.5 The structure of snakin-1 appears to be novel, different to known classes of cysteine-rich plant antimicrobial peptide. Its features include a large and distinctly electropositive loop that we speculate to be membrane targeting, and a two helix bundle which is a potential membrane-interacting feature able to disrupt the structural integrity of its target bacteria.

  • 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.

    Conference poster

    While cities are generally major sources of anthropogenic carbon dioxide (CO2) emissions, recent research has shown that parts of urban areas may also act as CO2 sinks due to CO2 uptake by vegetation. However, currently available results are related to a large degree of uncertainty due to the limitations of the applied methods and the limited number of studies available from urban areas, particularly from the southern hemisphere. In this study, we explore the potential of eddy covariance and tracer measurements (13C and 14C isotopes of CO2) to quantify and partition CO2 fluxes and concentrations in a residential urban area in Auckland, New Zealand. Based on preliminary results from autumn and winter (March to July 2014) the residential area is a small source of CO2 (0.11 mol CO2 m-2 day-1). CO2 fluxes and concentrations follow a distinct diurnal cycle with a morning peak between 7:00 and 9:00 (max: 0.25 mol CO2 m-2 day-1/412 ppm) and midday low with negative CO2 fluxes (min: -0.17 mol CO2 m-2 day-1/392 ppm) between 10:00 and 15:00 local time, likely due to photosynthetic CO2 uptake by local vegetation. Soil CO2 efflux may explain that CO2 concentrations increase and remain high (401 ppm) throughout the night. Mean diurnal winter delta13C values are in anti-phase with CO2 concentrations and vary between -9.0 - -9.70/00. The depletion of delta13C compared to clean atmospheric air (-8.20/00) is likely a result of local CO2 sources dominated by gasoline combustion (appr. 60%) during daytime. A sector analysis (based on prevailing wind) of CO2 fluxes and concentrations indicates lower CO2 fluxes and concentrations from the vegetation-dominated sector, further demonstrating the influence of vegetation on local CO2 concentrations. These results provide an insight into the temporal and spatial variability CO2 fluxes/concentrations and potential CO2 sinks and sources from a city in the southern hemisphere and add valuable information to the global database of urban CO2 fluxes.

  • Development of an organisational memory scale

    Dunham, Annette (2007-12-06)

    Conference poster
    The University of Auckland Library

    In many countries, people are retiring earlier than ever before and the retirement of the baby boom generation over the next two decades further intensifies the impact of this trend. Accompanying this development, are fears about the potential loss of organisational knowledge or memory which may equate to the loss of the organisation’s competitive advantage. Organisations, while recognizing that older workers often possess valuable “organisational memory” seem to also assume these same workers will readily divest themselves of their knowledge. Encouraging experienced workers to act as a mentor to younger or less experienced workers, is often mentioned in the management and related literature as a way of capturing and retaining valuable organisational knowledge. However, employees (including older workers) in the possession of considerable organisational memory, may, or may not be willing to divulge their knowledge to others, for a number of reasons. This poster presents initial results from the first of a series of studies designed to examine the relationship between organisational memory in the individual and propensity to mentor. It outlines the development and exploratory factor analysis of an “Organisational Memory” scale that taps the individual’s own resources in terms of organisational knowledge and expertise. Subsequent studies in the proposed research aim to help organisations more effectively target potential mentors for the purposes of retaining organisational knowledge, while also identifying the relevant costs and benefits of mentoring perceived by those individuals. By doing so it is hoped organisations will have a clearer understanding of how they can minimize costs while emphasising the benefits of such a relationship for the potential mentor. In contrast to the “development outcomes” focus of much of the mentoring literature, these studies give attention to the “knowledge sharing role of mentoring, while also touching on developmental outcomes, in this case, for the mentor

    We report on an experimental method to measure conductivity of cortical tissue. We use a pair of 5mm diameter Ag/AgCl electrodes in a Perspex sandwich device that can be brought to a distance of 400 microns apart. The apparatus is brought to uniform temperature before use. Electrical impedance of a sample is measured across the frequency range 20 Hz-2.0 MHz with an Agilent 4980A four-point impedance monitor in a shielded room. The equipment has been used to measure the conductivity of mature mouse brain cortex in vitro. Slices 400 microns in thickness are prepared on a vibratome. Slices are bathed in artificial cerebrospinal fluid (ACSF) to keep them alive. Slices are removed from the ACSF and sections of cortical tissue approximately 2 mm times 2 mm are cut with a razor blade. The sections are photographed through a calibrated microscope to allow identification of their cross-sectional areas. Excess ACSF is removed from the sample and the sections places between the electrodes. The impedance is measured across the frequency range and electrical conductivity calculated. Results show two regions of dispersion. A low frequency region is evident below approximately 10 kHz, and a high frequency dispersion above this. Results at the higher frequencies show a good fit to the Cole-Cole model of impedance of biological tissue; this model consists of resistive and non-linear capacitive elements. Physically, these elements are likely to arise due to membrane polarization and migration of ions both intra- and extra-cellularly.

    Conference poster

    Demographic evidence indicates that learners in Aotearoa-New Zealand are increasingly likely to speak more than one language and that this is most evident in the Auckland region. These trends suggest emerging challenges for researchers and practitioners. This poster presents our TLRI* research, in progress, which documents the diversity of language use and experiences of children in early childhood education and care in the Auckland region. The collaborative research team includes University of Auckland researchers and teacherresearchers in four early childhood centres: a Māori-medium centre, a Samoan immersion centre, and a kindergarten and a centre with children from a wide range of heritage language backgrounds. Theoretical frameworks influencing the design and analyses include an additive approach to bilingual activity and contexts that views children as potentially capable. The research (2013-2015) addresses three questions: 1. What languages do children from participating ECE centres use in their learning in the centre and at home? 2. What experiences and outcomes for children who learn in more than one language in the early years are valued by parents, teachers, and children? 3. How might the opportunities and challenges for children who learn in more than one language be addressed in educational practice? Objectives within each of the four partner-centre settings are to: · document the languages spoken by children, parents, and teachers in the ECE centre and at home · document and interpret the learning experiences of young children who learn in more than one language (as valued by parents, teachers, and children) · document the valued outcomes for young children who learn in more than one language · in partnership between teacher-researchers and University of Auckland researchers, analyse and theorise the data gathered, using funds of knowledge and additive bilingualism approaches, to build on understandings of the learning and teaching of children who learn in more than one language, and · analyse and theorise, using an 'additive approach' (to bilingualism, immersion, or multi-literacies), to extend understandings of the learning and teaching of children who learn in more than one language.) Research team members are using a range of qualitative and quantitative approaches to generate data about the experiences, opportunities, and challenges associated with learning in more than one language. Methods/tools include: questionnaires for parents and teachers, focus group interviews with parents and teachers, and fieldnote observations of arrivals and departures at the centres, videotaped observations of children's learning experiences in ECE settings, and conversations with children. In the poster session, aspects of these processes will be discussed. This research is significant, given the demographics and that there are gaps in current knowledge about learning experiences, valued outcomes and possible futures for children who are learning in more than one language in their ECE and (or) their family environments. Our study is designed to contribute new findings and to advance knowledge and practice about children learning in more than one language in the early years.

  • An optimal sampling schedule for neonates, infants & children receiving cefazolin +/- vancomycin for cardiopulmonary bypass

    Sturge, Jacqueline; Anderson, Brian; Holford, Nicholas (2016-08-22)

    Conference poster
    The University of Auckland Library

    Background: Dosing of prophylactic antibiotics in children during cardiopulmonary bypass (CPB) remains poorly defined. Pharmacokinetic (PK) studies can be improved using optimal design when sampling is limited, or multiple factors influence PK. We aimed to optimize a sampling schedule designed to determine cefazolin and vancomycin PK in children undergoing CPB. Methods: A one compartment distribution model for vancomycin and a three compartment distribution model for cefazolin was used with theory based allometric scaling and maturation to describe first-order elimination clearance. The CPB circuit was represented by an additional compartment. We assumed 60 subjects received cefazolin 50 mg.kg-1, with 50 of these subjects undergoing a procedure with CPB. We assumed 15 subjects also received 15 mg.kg-1 vancomycin. Optimal times for up to 8 samples per patient were estimated, ignoring CPB effects, using WinPOPT (University of Otago, New Zealand). Optimal sampling times for determination of CPB related changes were considered separately. Designs were selected based on relative standard errors (RSEs) for model parameters and comparison of criterions summarizing design efficiency. Results: Sample times were 0.001, 0.001, 0.108, 0.36, 1.05, 1.85 h following the first dose, and 0.36 and 2.5 h after the second dose, for With CPB subjects. Sample times were 0.127, 0.43, 0.43, 1.3, 3.18, 6, 6 h after the first dose and 6 h after the second dose, for Without CPB subjects. Five samples, taken directly from the CPB circuit, were required to adequately capture CPB related changes in CPB V and CL. RSE estimates of cefazolin, vancomycin and CPB circuit parameters for the final design were ≤ 30%, with the exception of one of the cefazolin volumes (V2) for which RSEs were 49%. Conclusion: The sampling schedule may be used in the planning of a clinical study of children receiving cefazolin and vancomycin during CPB.

  • Considering clinical protocols and guidelines: what lessons for IPE?

    Barrow, Mark; Gasquoine, S (2016-08-30)

    Conference poster
    The University of Auckland Library

    Background: Interprofessional collaboration is enhanced if professionals work across discursive boundaries. While interprofessional education interventions may encourage this the practice environment may militate against the implementation of understandings developed in educational settings. Summary of work: Interviews with doctors and nurses highlighted differences between each professions’ views of clinical protocols and guidelines. This prompted us to conduct a critical discourse analysis of a number of clinical guidelines and the systems which guide their development and approval. Summary of results: Our analysis shows a range of discourses at work within clinical protocols régimes. Development and approval systems are dominated by collectivist discourses emphasising communication and collaboration within rigid bureaucratic systems. The protocols exemplify a neo-liberal discourse where people who are the objects of care are positioned as clients or consumers amenable to standardised aliquots of diagnosis and care, the level of which can be justified on the basis of scoring systems and claims related to a ‘scientific’ evidence base. The régimes also suggests (perhaps falsely) flattened hierarchical structures, a democratising discourse where all professional voices are equal in the provision of care. Discussion: A nursing identity relies on experience, holistic views of patients and collective approaches to practice. The medical identity is based on craft-based development of expertise associated with generating distinctive and sometime idiosyncratic responses to a patient’s needs. Each comes to protocols with different ‘agenda’. Conclusions: The collectivist discourse of protocol development does not seem to carry through to their utilisation. Protocols appear to act as objects that reinforce discursive boundaries between the groups. Take-home messages: Educators need to consider the effect of protocols on practice and account for this in the design of educational interventions. Understanding the discursive roll of protocols might help educators design more robust IPE programmes.

  • Synthesis and mechanistic studies of PLA₂ inihibition by the marine alkaloid hyrtiosulawesine

    Conference poster
    The University of Auckland Library

    The first isolation of hyrtiosulawesine (1) was from an Indonesian collection of the marine sponges Hyrtios erectus and H. reticulatus.1 The β-carboline alkaloid was subsequently re-isolated from a Red Sea collection of Hyrtios sp. and found to display anti-phospholipase A2 (PLA2) activity with an IC50 value of 14 μM. Phospholipase A2 catalyses the hydrolysis of membrane phospholipids at the sn-2 position to generate arachidonic acids (AA).3,4 AA are precursors to a large family of compounds known as the eicosanoids associated with inflammatory reactions.4 PLA2 inhibition by hyrtiosulawesine would lead to a decrease in AA and proinflammatory eicosanoids, with anti-inflammatory effect.4 In an effort to understand the structural attributes of the natural product (1) that cause PLA2 inhibition, hyrtiosulawesine and a series of related model compounds (2, 3) will be synthesised and evaluated for biological activity. Biomimetic nucleophiles will be used to probe hyrtiosulawesine and related compounds in order to determine their reactivity and possible site of reaction. Bioactive members of the library of compounds will subsequently be subjected to reaction with bee venom phospholipase A2 to identify the presence of any covalent adducts. Further studies may be directed to discovering the nature and location of the covalent linkage within the enzyme active site. The latest results will be presented. References 1.

  • The potential of urban forests to mitigate atmospheric CO2 concentrations

    Weissert, Lena; Salmond, Jennifer; Schwendenmann, Luitgard (2013)

    Conference poster
    The University of Auckland Library

    The urban population in New Zealand is expected to increase significantly over the next years. Urban areas are generally large sources of anthropogenic carbon dioxide (CO2) emissions. However, attempts to quantify atmospheric CO2 concentrations and fluxes have suggested that densily vegetated urban areas may absorb sufficient quantities of anthropogenic CO2 to act as a local sink. Consequently, urban greening programs now form an important part of many urban climate change mitigation policies globally as well as in New Zealand. However, knowledge about the direct contribution of urban vegetation on atmospheric CO2 concentrations is still limited and measurements scarce. This paper examines the methods used to date to estimate / measure carbon pools and CO2 fluxes from urban vegetation and soils (collectively known as urban forests) and aggregates currently available results. Results from the northern hemisphere show that carbon pools in urban forests were comparable to 3 – 60% of the annually released fossil fuel emissions, while photosynthetic uptake accounted for 0.3 – 2.6% of the total estimated emissions in urban areas. Whilst vegetation did not offset CO2 emissions on an annual basis in these scenarios, vegetative CO2 uptake resulted in significantly lower atmospheric CO2 concentrations in summer. However, the currently available results are related to a large degree of uncertainty due to the limitations of the applied methods, the limited number of urban areas studied and the temporal / spatial resolution of the fieldwork. This paper demonstrates that in order to effectively quantify and encorporate carbon fluxes from urban areas into annual CO2 budgets, future research needs to use a combination of methodologies and be aware of the scales of their studies. Thus, before investing in urban greening programs the potential of urban vegetation as a climate change mitigation measure needs to be further investigated, particularly for cities in the southern hemisphere.

  • Baby, Baby: Pregnant Again After Postnatal Depression

    Cowie, Susan (2008-09-10)

    Conference poster
    The University of Auckland Library

    Depression following birth has wide ranging impacts on the woman, her new baby and her family. Studies indicate that treatment has been effective in shortening the duration of depression but does not prevent the increased risk of experiencing depression following another birth. This study explores in detail women’s and practitioners understandings of first time mother’s experiences of and recovery from depression and then focus on how the women prepare for and make sense of the experience of second time pregnancy and motherhood. It is hoped to develop strategies to reduce recurrence and impact of depression in women with young children. Results are presented of interviews with 25 women who had previously experienced post natal depression. Interviews were conducted 3-6 months before birth, focusing firstly on how the women make sense of their transition to first time motherhood and coping with/recovery from depression and secondly, on their expectations of second time birth and motherhood. The second interview, completed 3 months after birth, focused on their experience of the pregnancy, birth, and life with another child. Qualitative methodologies were employed. Of particular interest were the things that women described as helpful and unhelpful, their understanding of the help/treatment (e.g. Home help, CBT, support group, Arapax) they had gained and how this influenced their decisions and coping second time round. Preliminary analyses, particularly of time one data (collection complete), are reported and issues related to the study design and implementation are discussed.
