Monitoring of lactate in interstitial fluid, saliva and sweat by electrochemical biosensor: the uncertainties of biological interpretation
Lactate electrochemical biosensors were fabricated using Pediococcus sp lactate oxidase (E.C. 1.1.3.2), an external polyurethane membrane laminate diffusion barrier and an internal ionomeric polymer barrier (sulphonated polyether ether sulphone polyether sulphone, SPEES PES). In a needle embodiment, a Pt wire working electrode was retained within stainless steel tubing serving as pseudoreference. The construct gave linearity to at least 25 mM lactate with 0.17 nA/mM lactate sensitivity. A low permeability inner membrane was also unexpectedly able to increase linearity. Responses were oxygen dependent at pO2 < 70 mmHg, irrespective of the inclusion of an external diffusion barrier membrane. Subcutaneous tissue was monitored in Sprague Dawley rats, and saliva and sweat during exercise in human subjects. The tissue sensors registered no response to intravenous Na lactate, indicating a blood-tissue lactate barrier. Salivary lactate allowed tracking of blood lactate during exercise, but lactate levels were substantially lower than those in blood (0â3.5 mM vs. 1.6â12.1 mM), with variable degrees of lactate partitioning from blood, evident both between subjects and at different exercise time points. Sweat lactate during exercise measured up to 23 mM but showed highly inconsistent change as exercise progressed. We conclude that neither tissue interstitial fluid nor sweat are usable as surrogates for blood lactate, and that major reappraisal of lactate sensor use is indicated for any extravascular monitoring strategy for lactate
Orangutans venture out of the rainforest and into the Anthropocene
Conservation benefits from understanding how adaptability and threat interact to determine a taxonâs vulnerability. Recognizing how interactions with humans have shaped taxa such as the critically endangered orangutan (Pongo spp.) offers insights into this relationship. Orangutans are viewed as icons of wild nature, and most efforts to prevent their extinction have focused on protecting minimally disturbed habitat, with limited success. We synthesize fossil, archeological, genetic, and behavioral evidence to demonstrate that at least 70,000 years of human influence have shaped orangutan distribution, abundance, and ecology and will likely continue to do so in the future. Our findings indicate that orangutans are vulnerable to hunting but appear flexible in response to some other human activities. This highlights the need for a multifaceted, landscape-level approach to orangutan conservation that leverages sound policy and cooperation among government, private sector, and community stakeholders to prevent hunting, mitigate human-orangutan conflict, and preserve and reconnect remaining natural forests. Broad cooperation can be encouraged through incentives and strategies that focus on the common interests and concerns of different stakeholders. Orangutans provide an illustrative example of how acknowledging the long and pervasive influence of humans can improve strategies to preserve biodiversity in the Anthropocene
Aesthetics and Psychological Effects of Fractal Based Design
Highly prevalent in nature, fractal patterns possess self-similar components that repeat at varying size scales. The perceptual experience of human-made environments can be impacted with inclusion of these natural patterns. Previous work has demonstrated consistent trends in preference for and complexity estimates of fractal patterns. However, limited information has been gathered on the impact of other visual judgments. Here we examine the aesthetic and perceptual experience of fractal âglobal-forestâ designs already installed in humanmade spaces and demonstrate how fractal pattern components are associated with positive psychological experiences that can be utilized to promote occupant wellbeing. These designs are composite fractal patterns consisting of individual fractal âtree-seedsâ which combine to create a âglobal fractal forest.â The local âtree-seedâ patterns, global configuration of tree-seed locations, and overall resulting âglobal-forestâ patterns have fractal qualities. These designs span multiple mediums yet are all intended to lower occupant stress without detracting from the function and overall design of the space. In this series of studies, we first establish divergent relationships between various visual attributes, with pattern complexity, preference, and engagement ratings increasing with fractal complexity compared to ratings of refreshment and relaxation which stay the same or decrease with complexity. Subsequently, we determine that the local constituent fractal (âtree-seedâ) patterns contribute to the perception of the overall fractal design, and address how to balance aesthetic and psychological effects (such as individual experiences of perceived engagement and relaxation) in fractal design installations. This set of studies demonstrates that fractal preference is driven by a balance between increased arousal (desire for engagement and complexity) and decreased tension (desire for relaxation or refreshment). Installations of these composite mid-high complexity âglobal-forestâ patterns consisting of âtree-seedâ components balance these contrasting needs, and can serve as a practical implementation of biophilic patterns in human-made environments to promote occupant wellbeing

Political Marketing Activity in Simultaneous Regional Elections 2015
Regional head election system was change in 2015. It has impact on political marketing strategy to all stake holders, such as political party and candidatures.The purposes of this research is to analyzeashifting ofpolitical marketing issueson regional election 2015. The research approach uses the mix method with the type of sequential explanatory. The subjects of this research are the candidates, election successful teams or supporting team, and young voters. Location of research based on cluster system district and sub district in Bandung, Cianjur, Magelang, Sleman, and Medan. The data are collected through techniques of questionnaires to young voters; interview to candidates, election successful teams and young voters, as well as the documentation of media and data on Regional General Elections Commission (KPUD). There are also triangular data techniqueinterviews with the General Elections Commission (KPU), the community and supporting team, and documentation and questionnaire form. The result shows that the system of political marketing has already started shifting from product, promotion, price, place, and people known as the 5Ps from mostly dominated by Political Partyinto the role of PEOPLE as candidature in influensing the voters. The Result also tells that shifting from using convetional media into almost using digital media was powerfull
Immigration into the mainstream: Conflicting ideological streams, strategic reasoning and party competition
More and More Restrictive-But Not Always Populist: Explaining Variation in the British Conservative Party's Stance on Immigration and Asylum
This is the Author's Accepted Manuscript of an article published in the Journal of Contemporary European Studies Vol. 21, Iss. 1, copyright Taylor & Francis 2013, available online at: http://www.tandfonline.com/10.1080/14782804.2013.766474Centre-right parties are commonly inclined towards appeals and policies on immigration that are both restrictive in nature and populist in tone-in part because this is what they believe in, in part because it affords them an electoral advantage over their rivals on the centre-left. One would expect, however, that the extent to which they focus on immigration and asylum will vary according to public opinion, according to who leads them, and according to whether they are in government or in opposition. This would appear to be the case for the British Conservative Party, but the relationship is not an entirely consistent one. Moreover, while the Party has, for half a century, pursued ever more restrictive policies, the extent to which it has couched its approach in populist rhetoric varies considerably over time-and not always in line with the severity of its stance on immigration. The reason for this lies partly in the social and economic liberalism of some of its leaders (and in their related concern to act 'responsibly' on race and immigration) but also in their anxiety not to alienate key sections of the middle classes who must be persuaded to support the Party if it is to win elections. These considerations are likely to weigh heavily with other centre-right parties, too. © 2013 Copyright Taylor and Francis Group, LLC
