Abstract
Enhancement of endothelialization and patency of a small diameter (2 mm), wide pore, PTFE graft was attempted by coating the luminal surface with a platelet derived angiogenesis fraction (PDAF) and implanting it in a rat model. PDAF was delivered to the grafts by combining it with a carrier polymer. PDAF-treated grafts were initially implanted in the retroperitoneum for 21 days followed by removal of one for histology and in situ end to side bypass to the infrarenal aorta for the other. Vascularized grafts were examined at 14 days for patency and 100 days for patency and histology. Significant differences were noted in transmural ingrowth of capillaries and tissue at 21 days post implantation in PDAF-treated verses untreated grafts. Similarly, near significance was noted in capillary ingrowth and significance was noted in tissue ingrowth at 100 days in PDAF-treated grafts. Despite favorable trends particularly early in the time course, no significant differences in graft patency, endothelialization, or hydroxyproline content was demonstrated between PDAF-treated and untreated grafts. Results of this preliminary study are encouraging for further study of PDAF-treated PTFE grafts and the potential that rapid vascularized neointima formation results improved in graft patency rates.

Abstract
BACKGROUND AND OBJECTIVES It is expected that the graduating dental student will have acquired the skills and knowledge to confidently treat most circumstances that they may encounter in private practice. The aims of this study were to evaluate final year dental students' self-reported levels of confidence in expected core skills just prior to graduation and to explore their career intentions both directly after graduating as well as in the longer term. METHODS After ethical approval was obtained, a survey and participant information sheet was distributed to all final year undergraduate dental students in 2014. Statistical analysis was carried out using SPSS version 22.0 with the alpha value set at 0.05. RESULTS The response rate was 69% (58/84). Most (44.8%) were going to be working in New Zealand private practices with 34.5% definitely considering specializing. The majority reported high self-confidence levels for sealant restorations (96.6%) and radiography (94.8%), while very few were confident in carrying out soft tissue biopsies (1 .8%) or restoring dental implants and treating medical emergencies (10.5%). Some gender differences were found. CONCLUSIONS The general finding was that most NZ graduates perceived themselves to be confident in managing the most fundamental aspects of general practice. Similar to their counterparts around the world, they will benefit from further mentoring and additional exposure to the more complex clinical tasks such as the restoration of implants and soft tissue biopsies.

Abstract
BACKGROUND AND OBJECTIVES Sugar, a known aetiological factor in dental decay, has been used in paediatric medications as a bulking agent, preservative and to improve taste. Although artificial sweeteners have largely replaced sugar, some prescribed and over-the-counter (OTC) paediatric medications and supplements containing sugar are still available in New Zealand. Little is currently known about the knowledge, opinions and practices of staff in NZ pharmacies regarding sugar-containing paediatric medications. This study was carried out to investigate these factors. METHODS After ethical approval was obtained, questionnaires were delivered to all staff members at pharmacies in the greater Dunedin area. Quantitative statistical analysis was carried out using SPSS version 22.0 with the alpha value set at 0.05. Qualitative data were analysed using a general inductive technique. RESULTS A total of 58 questionnaires were returned giving a pharmacy response rate of 63.0%. Some 29.9% of respondents thought the inclusion of sugar in medications necessary and 77.6% agreed that sugar in paediatric medications can contribute to dental decay. Most of the 67.2% who reported that they do not give advice to customers regarding sugar in medications and oral health, felt it was not a priority. Parental request was the main factor determining provision or recommendations regarding sugar-free options (87.9%). CONCLUSION Although choice of a sugar-free medication can be limited by many factors, inter-professional collaboration and knowledge sharing on this topic would be advantageous. In addition, the provision of more formalised education, either as part of undergraduate pharmacy curricula or as part of continuing education, should be considered.

Abstract
BACKGROUND AND OBJECTIVES Among other restorative strategies, the Accident Compensation Corporation (ACC) provides benefits for dental implant treatment to replace teeth lost as a result of trauma. While ACC has funded over 15,000 dental implants since 2002, the outcomes of this treatment and patient perceptions of this treatment have not been investigated. The aim of this study was to investigate the perceptions of the dental implant treatment outcomes and reasons for failure to complete restorative treatment in patients who had undergone trauma-related implant surgery funded by ACC between February 2006 and September 2009, but had not completed the prosthetic component of the treatment. METHODS A randomly selected sample of 399 patients, who had undergone dental implant surgery but not completed the crown restoration, was identified from the ACC database. These individuals were contacted by mail for expressions of interest and 181 clients were interviewed by telephone. Responses to open-ended questions were entered into an Excel spreadsheet and analysed using a general inductive technique. RESULTS A common emergent theme was the high level of satisfaction expressed by participants with the implant process, however just under half of those responding felt they had been pushed into having implants and were given the impression that this was the only treatment ACC paid for. The cost of the prosthetic phase of the treatment and surgical complications were identified as the primary reasons why participants failed to complete the restorative phase of treatment, after completing the surgical phase. CONCLUSIONS The results highlighted the need to better inform patients of their treatment options and to allow time for them to process this information before progressing with care. A patient decision tool may help to give greater ownership of the treatment options. Newly implemented protocols to assist dentists to better assess treatment needs may also assist in achieving improvements in perceived treatment outcomes for patients.

Abstract
With increasing use of herbal medicines for chronic or serious illness, relevant quality assurance methods are essential for making claims of therapeutic benefit. Adequate demonstration of safety and efficacy based on chemical composition and ensuring consistency between manufactured batches is critical. To date, there has been no uniform standard approach or detailed framework provided to industry for selecting relevant chemical markers used to standardize herbal products. We developed the Herbal Marker Ranking System (Herb MaRS) providing guidance on prioritizing the selection of chemical markers for quality control of complex multi-herb mixtures, while also taking into account the bioactivity in relation to the symptoms of the disease and its concentration in the formula. We apply the Herb MaRS evaluation criteria to a seven-herb formulation for the treatment of irritable bowel syndrome with constipation. Our ranking scale accommodates the clinical and pharmacological use of the formulation and its claimed indications.

Abstract
Genetic polymorphisms in the APOE ɛ and TOMM40 '523' poly-T repeat gene loci have been associated with significantly increased risk of Alzheimer's disease. This study investigated the independent effects of these polymorphisms on human cognitive ageing, and the extent to which nominally significant associations with cognitive ageing were mediated by previously reported genetic associations with brain white matter tract integrity in this sample. Most participants in the Lothian Birth Cohort 1936 completed a reasoning-type intelligence test at age 11 years, and detailed cognitive/physical assessments and structural diffusion tensor brain magnetic resonance imaging at a mean age of 72.70 years (s.d.=0.74). Participants were genotyped for APOE ɛ2/ɛ3/ɛ4 status and TOMM40 523 poly-T repeat length. Data were available from 758-814 subjects for cognitive analysis, and 522-543 for mediation analysis with brain imaging data. APOE genotype was significantly associated with performance on several different tests of cognitive ability, including general factors of intelligence, information processing speed and memory (raw P-values all<0.05), independently of childhood IQ and vascular disease history. Formal tests of mediation showed that several significant APOE-cognitive ageing associations--particularly those related to tests of information processing speed--were partially mediated by white matter tract integrity. TOMM40 523 genotype was not associated with cognitive ageing. A range of brain phenotypes are likely to form the anatomical basis for significant associations between APOE genotype and cognitive ageing, including white matter tract microstructural integrity.

Abstract
Associations between brain cortical tissue volume and cognitive function in old age are frequently interpreted as suggesting that preservation of cortical tissue is the foundation of successful cognitive aging. However, this association could also, in part, reflect a lifelong association between cognitive ability and cortical tissue. We analyzed data on 588 subjects from the Lothian Birth Cohort 1936 who had intelligence quotient (IQ) scores from the same cognitive test available at both 11 and 70 years of age as well as high-resolution brain magnetic resonance imaging data obtained at approximately 73 years of age. Cortical thickness was estimated at 81 924 sampling points across the cortex for each subject using an automated pipeline. Multiple regression was used to assess associations between cortical thickness and the IQ measures at 11 and 70 years. Childhood IQ accounted for more than two-third of the association between IQ at 70 years and cortical thickness measured at age 73 years. This warns against ascribing a causal interpretation to the association between cognitive ability and cortical tissue in old age based on assumptions about, and exclusive reference to, the aging process and any associated disease. Without early-life measures of cognitive ability, it would have been tempting to conclude that preservation of cortical thickness in old age is a foundation for successful cognitive aging when, instead, it is a lifelong association. This being said, results should not be construed as meaning that all studies on aging require direct measures of childhood IQ, but as suggesting that proxy measures of prior cognitive function can be useful to take into consideration.
