Purpose of review: The shift of modern dietary regimens from 'Mediterranean' to 'western' style is believed to be responsible, in part, for the increase in cardiovascular disease, obesity, type II diabetes and cancer. A classic 'Mediterranean' diet consists of adequate intake of seafood, vegetables, fruit, whole grain and nonpurified monounsaturated vegetable oil. Thus, in humans, dietary intake of seafood is the major source of taurine, as the level of endogenously produced taurine is low. Recent findings: Taurine has been shown to affect coronary artery disease, blood pressure, plasma cholesterol and myocardial function in animal models of human disease. A major role of taurine is to act as an antioxidant and absorb hypochlorous acid but not the oxidative radical. It seems that this beneficial effect of taurine in antioxidant therapy has not been well promoted. Summary: This review will focus on determining whether taurine could be a factor contributing to the further prevention of heart disease. © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins.

(Figure Equotion Presented) Specific stimuli can be used to trigger the release of cargo encapsulated in polymer carriers in applications ranging from drug delivery to catalysis. Current approaches can be categorized in two classes: application of an external stimulus, such as light, and exploitation of environmental changes, such as chemical and enzymatic degradation (see picture). © 2010 Wiley-VCH Verlag GmbH & Co.

The goal of this article (letter to the editor) is to emphasize the value of exploring ranking stability when using the importance measures, mean decrease accuracy (MDA) and mean decrease Gini (MDG), provided by Random Forest. We illustrate with a real and a simulated example that ranks based on the MDA are unstable to small perturbations of the dataset and ranks based on the MDG provide more robust results. © The Author 2010.

The polysaccharide hyaluronan (HA) (synonyms - hyaluronic acid, hyaluronate) is a versatile, polymorphic, glycosoaminoglycan with vast biological functions. HA is found throughout the body, primarily residing in skin, thus playing an important role in wound healing. Research regarding HA's function has changed over the years, primarily focussing on a particular aspect or function. The contribution of HA in each stage of normal wound healing as well as its clinical wound dressing applications will be examined. © 2012 Inc and John Wiley & Sons Ltd.

This paper analyses the natural voltage-balancing characteristic of a three-phase flying capacitor multilevel converter when it is operated under the spectrally optimal Phase Disposition (PD) pulsewidth modulation (PWM) strategy. Using this analysis, it is shown that PD PWM has superior balancing characteristics compared to the phase-shifted carrier PWM strategy, because it places more spectral energy into the differential-mode sideband harmonics that drive the voltage-balancing process. From this understanding, an alternative balance booster filter network connection is proposed that significantly improves the natural balancing response of a flying capacitor converter for either PWM strategy. The analysis is confirmed by extensive simulation and experimental studies. © 2011 IEEE.

A symmetric self-Hilbertian filter is a product filter that can be used to construct orthonormal Hilbert-pair of wavelets for the dual-tree complex wavelet transform. Previously reported techniques for its design does not allow control of the filters frequency response sharpness. The Zero-Pinning (ZP) technique is a simple and versatile way to design orthonormal wavelet filters. ZP allows the shaping of the frequency response of the wavelet filter by strategically pinning some of the zeros of the parametric Bernstein polynomial. The non-zero Bernstein parameters, αis, are the free-parameters and are constrained in number to be twice the number of pinned zeros in ZP. An extension to ZP is presented here where the number of free-parameters is greater than twice the number of pinned zeros. This paper will show how the extended ZP can be used to the design of Hilbert pairs with the ability to shape the filter response. © 2011 Elsevier B.V. All Rights Reserved.

Background Team ball sports such as soccer, basketball and volleyball have high participation levels worldwide. Musculoskeletal injuries are common in team ball sports and are associated with significant treatment costs, participation loss and long-term negative side effects. The results of recent randomized controlled trials provide support for the protective effect of injury-prevention exercise programmes (IPEPs) in team ball sports, but also highlight that achieving adequate compliance can be challenging. A key process in enhancing the ultimate impact of team ball sport IPEPs is identifying the specific implementation components that influence the adoption, execution and maintenance of these interventions. Despite this, no systematic review focussing on the specific implementation components of team ball sport IPEPs has been conducted. Objectives Our objective was to assess the reporting of specific implementation components in the published literature on team ball sport IPEPs using the Reach Efficacy Adoption Implementation Maintenance (RE-AIM) framework. Methods Six electronic databases were systematically searched from inception to December 2012 for papers reporting team ball sport IPEP trials. All eligible papers were independently evaluated by two raters before reaching consensus on the reporting of individual RE-AIM items, using the RE-AIM Model Dimension Items Checklist (RE-AIM MDIC). Results A total of 60 papers, reporting 52 unique intervention trials, met eligibility criteria. Before consensus, the level of agreement across all trials between reviewers using the RE-AIM MDIC ranged from 81 to 91 %. The RE-AIM MDIC dimension of 'efficacy' had the highest level of reporting, with the five individual items in this dimension reported in 19-100 % of eligible trials (mean 58 %). The RE-AIM MDIC dimension 'maintenance-setting level' had the lowest level of reporting, with none of the four individual items in this dimension reported. For other dimensions, the mean level of reporting and range across items were 'reach' 34 % (12-60 %); 'adoption-setting level' 1 % (0-2 %); 'adoption-delivery agent level' 7 % (4-10 %); 'implementation' 36 % (13-63 %) and 'maintenance individual level' 1 % (0-4 %). Conclusion Information on the specific implementation components of team ball sport IPEPs in published studies is scarce. In particular, major reporting gaps exist regarding the adoption and maintenance of these programmes. The RE-AIM MDIC can be successfully applied to reviewing literature in this context. © 2014 Springer International Publishing Switzerland.

Where hemispheric lateralization was once considered an exclusively human trait, it is increasingly recognized that hemispheric asymmetries are evident throughout the animal kingdom. Emotion is a prime example of a lateralized function: given its vital role in promoting adaptive behavior and hence survival, a growing body of research in affective neuroscience is working to illuminate the cortical bases of emotion processing. Presuming that human and non-human primates evolved from a shared ancestor, one would anticipate evidence of organizational continuity in the neural substrate supporting emotion processing. This paper thus reviews research examining the patterns of lateralization for the expression and perception of facial emotion in non-human primates, aiming to determine whether the patterns of hemispheric asymmetry that characterize the human brain are similarly evident in other primate species. As such, this review seeks to enhance understanding of the evolution of hemispheric specialization for emotion, using emotion lateralization in non-human primates as a window through which to view emotion lateralization in humans. © 2013 Lindell.

Consensus decision making is complex and challenging in multicriteria group decision making due to the involvement of several decision makers, the presence of multiple, and often conflicting criteria, and the existence of subjectiveness and imprecision in the decision making process. To ensure effective decisions being made, the interest of all the decision makers usually represented by the degree of consensus in the decision making process has to be adequately considered. This paper presents a consensus-based approach for effectively solving the multicriteria group decision making problem. The subjectiveness and imprecision of the decision making process is adequately handled by using intuitionistic fuzzy numbers. An interactive algorithm is developed for consensus building in the group decision making process. A decision support system framework is presented for improving the effectiveness of the consensus building process. An example is presented for demonstrating the applicability of the proposed approach for solving the multicriteria group decision making problem in real world situations. © 2013 Elsevier Ltd.

Objectives To evaluate cigarette branding strategies used to segment a market with some of the toughest tobacco controls. To document brand variant and packaging portfolios and assess the role played by colour before plain packaging, as well as consider the threat that recently implemented legislation poses for tobacco manufacturers. Data sources Brand variant and packaging details were extracted from manufacturer ingredient reports, as well as a retail audit of Australian supermarkets. Details were also collected for other product categories to provide perspective on cigarette portfolios. Methods Secondary and primary data sources were analysed to evaluate variant and packaging portfolio strategy. Results In Australia, 12 leading cigarette brands supported 120 brand variants. Of these 61 had names with a specific colour and a further 26 had names with colour connotation. There were 338 corresponding packaging configurations, with most variants available in the primary cigarette distribution channel in four pack size options. Conclusions Tobacco companies microsegment Australian consumers with highly differentiated product offerings and a family branding strategy that helps ameliorate the effects of marketing restrictions. To date, tobacco controls have had little negative impact upon variant and packaging portfolios, which have continued to expand. Colour has become a key visual signifier differentiating one variant from the next, and colour names are used to extend brand lines. However, the role of colour, as a heuristic to simplify consumer decisionmaking processes, becomes largely redundant with plain packaging. Plain packaging’s impact upon manufacturers’ branding strategies is therefore likely to be significant. © 2015, BMJ Publishing Group. All rights reserved.
