The chytrid fungus Batrachochytrium dendrobatidis has been implicated in the decline and extinction of numerous frog species worldwide. In Queensland, Australia, it has been proposed as the cause of the decline or apparent extinction of at least 14 high-elevation rainforest frog species. One of these, Taudactylus eungellensis, disappeared from rainforest streams in Eungella National Park in 1985-1986, but a few remnant populations were subsequently discovered. Here, we report the analysis of B. dendrobatidis infections in toe tips of T. eungellensis and sympatric species collected in a mark-recapture study between 1994 and 1998. This longitudinal study of the fungus in individually marked frogs sheds new light on the effect of this threatening infectious process in field, as distinct from laboratory, conditions. We found a seasonal peak of infection in the cooler months, with no evidence of interannual variation. The overall prevalence of infection was 18% in T. eungellensis and 28% in Litoria wilcoxii/jungguy, a sympatric frog that appeared not to decline in 1985-1986. No infection was found in any of the other sympatric species. Most importantly, we found no consistent evidence of lower survival in T. eungellensis that were infected at the time of first capture, compared with uninfected individuals. These results refute the hypothesis that remnant populations of T. eungellensis recovered after a B. dendrobatidis epidemic because the pathogen had disappeared. They show that populations of T. eungellensis now persist with stable, endemic infections of B. dendrobatidis.

The small GTPase Rab5 is a key regulator of clathrin-mediated endocytosis. On early endosomes, within a spatially restricted domain enriched in phosphatydilinositol-3-phosphate [PI(3)P], Rab5 coordinates a complex network of effectors that functionally cooperate in membrane tethering, fusion, and organelle motility. Here we discovered a novel PI(3)P-binding Rab5 effector, Rabankyrin-5, which localises to early endosomes and stimulates their fusion activity. In addition to early endosomes, however, Rabankyrin-5 localises to large vacuolar structures that correspond to macropinosomes in epithelial cells and fibroblasts. Overexpression of Rabankyrin-5 increases the number of macropinosomes and stimulates fluid-phase uptake, whereas its downregulation inhibits these processes. In polarised epithelial cells, this function is primarily restricted to the apical membrane. Rabankyrin-5 localises to large pinocytic structures underneath the apical surface of kidney proximal tubule cells, and its overexpression in polarised Madin-Darby canine kidney cells stimulates apical but not basolateral, non-clathrin-mediated pinocytosis. in demonstrating a regulatory role in endosome fusion and (macro) pinocytosis, our studies suggest that Rab5 regulates and coordinates different endocytic mechanisms through its effector Rabankyrin-5. Furthermore, its active role in apical pinocytosis in epithelial cells suggests an important function of Rabankyrin-5 in the physiology of polarised cells.

Background Cardiovascular diseases and their nutritional risk factors-including overweight and obesity, elevated blood pressure, and cholesterol-are among the leading causes of global mortality and morbidity, and have been predicted to rise with economic development. Methods and Findings We examined age-standardized mean population levels of body mass index (BMI), systolic blood pressure, and total cholesterol in relation to national income, food share of household expenditure, and urbanization in a cross-country analysis. Data were from a total of over 100 countries and were obtained from systematic reviews of published literature, and from national and international health agencies. BMI and cholesterol increased rapidly in relation to national income, then flattened, and eventually declined. BMI increased most rapidly until an income of about I$5,000 (international dollars) and peaked at about I$12,500 for females and I$17,000 for males. Cholesterol's point of inflection and peak were at higher income levels than those of BMI (about I$8,000 and I$18,000, respectively). There was an inverse relationship between BMI/cholesterol and the food share of household expenditure, and a positive relationship with proportion of population in urban areas. Mean population blood pressure was not correlated or only weakly correlated with the economic factors considered, or with cholesterol and BMI. Conclusions When considered together with evidence on shifts in income-risk relationships within developed countries, the results indicate that cardiovascular disease risks are expected to systematically shift to low-income and middle-income countries and, together with the persistent burden of infectious diseases, further increase global health inequalities. Preventing obesity should be a priority from early stages of economic development, accompanied by population-level and personal interventions for blood pressure and cholesterol.

Since the early 1970s, when cannabis first began to be widely used [1], the proportion of young people who have used cannabis has steeply increased and the age of first use has declined [2, 3]. Most cannabis users now start in the mid-to-late teens [1], an important period of psychosocial transition when misadventures can have large adverse effects on a young person's life chances.

This essay explores the relationship between the development of public libraries in the context of an increasingly market-dominated economy and marketised society. It argues that although neo-liberalism as a policy goal and practice has taken different forms over time, there are common themes in terms of its emphasis on market values, privatisation, and the support of measures that reduce the role of public funding and the state in the provision of public services. This has led some commentators to express concerns that the meaning and practice of citizenship and democracy is being transformed, managed or otherwise diminished. These concerns are compounded by changes effected by new digital technology. Imbricated with this issue are debates surrounding the future of the public library, and attempts by librarians and others to reinvent and reimagine its purpose. With reference to some innovative initiatives in the USA and Scandinavia, it is suggested that public libraries, through their service and spatial rearticulation, can conceivably help strengthen and revitalise public democracy and the public sphere.

In the last decade the principle of Open Access to publicly funded research has been getting a growing support from policy makers and funders across Europe, both at national level and within the European Union context. At European level some of the first relevant steps taken by the European Research Council (ERC) with a statement supporting Open Access (2006), shortly followed by guidelines for researchers funded by the ERC (2007) stating that all peer-reviewed publications from ERC funded projects should be made openly accessible shortly after their publication. Those guidelines were revised in October 2013, reinforcing the mandatory character of the requirements and expanding them to monographs.

Wind- induced exposure is one of the major forces shaping the geomorphology and biota in coastal areas. The effect of wave exposure on littoral biota is well known in marine environments (Ekebon et al., 2003; Burrows et al., 2008). In the Cabrera Archipelago National Park wave exposure has demostrated to have an effect on the spatial distribution of different stages of E.marginatus (Alvarez et al., 2010). Standarized average wave exposures during 2008 along the Cabrera Archipelago National park coast line were calculated to be applied in studies of littoral species distribution within the archipelago. Average wave exposure (or apparent wave power) was calculated for points located 50 m equidistant on the coastline following the EXA methodology (EXposure estimates for fragmented Archipelagos) (Ekebon et al., 2003). The average wave exposures were standardized from 1 to 100 (minimum and maximum in the area), showing coastal areas with different levels of mea wave exposure during the year. Input wind data (direction and intensity) from 2008 was registered at the Cabrera mooring located north of Cabrera Archipelago. Data were provided by IMEDEA (CSIC-UIB, TMMOS http://www.imedea.uib-csic.es/tmoos/boyas/). This cartography has been developed under the framework of the project EPIMHAR, funded by the National Park's Network (Spanish Ministry of Environment, Maritime and Rural Affairs, reference: 012/2007 ). Part of this work has been developed under the research programs funded by "Fons de Garantia Agrària i Pesquera de les Illes Balears (FOGAIBA)".

Jusqu’à son suicide dans la nuit du 12 au 13 mars 1990, à l’âge de 86 ans, Bruno Bettelheim a marqué l’histoire de la psychologie. Dix-sept ouvrages, dont quatre écrits en collaboration, constituent, pour l’essentiel, sa contribution originale au traitement de l’autisme infantile : une thérapie de milieu, entièrement fondée sur les travaux de Freud. Certains n’hésitent pas, d’ailleurs, à le considérer comme un pionnier de l’histoire de la psychanalyse. Après sa mort, cependant, les langues se délient. D’anciens pensionnaires de l’école orthogénique de Chicago racontent que Bettelheim les battait, témoignages corroborés par d’anciens membres du personnel. Des proches collaborateurs ont même affirmé que Bettelheim mentait tout le temps, mensonges qui ont contribué à créer « le mythe Bettelheim », bien décrit dans l’ouvrage de Pollak (1997/2003), Bruno Bettelheim ou la fabrication d’un mythe. L’objectif de ce texte n’est pas d’aborder l’ensemble des reproches adressés à Bettelheim et à son oeuvre, mais d’examiner les failles de son fameux ouvrage Psychanalyse des contes de fées (Bettelheim, 1976). Salué par deux prix en 1977 (National Book Critics Circle Award et National Book Award), Psychanalyse des contes de fées reste, sans conteste, le plus grand succès populaire de tous ses ouvrages, tant aux États-Unis d’Amérique que dans les pays francophones. En 1995, la New York Public Library plaçait l’ouvrage parmi les 159 « livres du siècle », en dépit des quelques critiques dévastatrices parues dès sa sortie (Arthur, 1978 ; Blos, 1978 ; Heisig, 1977 ; Lurie, 1976 ; Zipes, 1979), dont une accusation de plagiat, laquelle accusation réapparaîtra après sa mort (Dundes, 1991b ; Pollak, 1997/2003). Nous présenterons, d’abord, le point de vue de Bettelheim, quant aux bienfaits, pour les enfants, de s’entendre raconter, par un adulte, les contes de fées. Nous verrons alors, à notre grande surprise, que la valeur qu’il leur accorde, en utilisant une grille psychanalytique, est non seulement largement exagérée, mais contraire aux données empiriques et historiques. Le recours de Bettelheim à la notion du complexe d’OEdipe, largement commentée dans son ouvrage, servira d’exemple. Nous discuterons brièvement, ensuite, du silence de Bettelheim sur les auteurs qui ont écrit sur le sujet et de l’accusation de plagiat portée contre lui.

Background: Parental obesity is a predominant risk factor for childhood obesity. Family factors including socio-economic status (SES) play a role in determining parent weight. It is essential to unpick how shared family factors impact on child weight. This study aims to investigate the association between measured parent weight status, familial socio-economic factors and the risk of childhood obesity at age 9. Methodology/Principal Findings: Cross sectional analysis of the first wave (2008) of the Growing Up in Ireland (GUI) study. GUI is a nationally representative study of 9-year-old children (N = 8,568). Schools were selected from the national total (response rate 82%) and age eligible children (response rate 57%) were invited to participate. Children and their parents had height and weight measurements taken using standard methods. Data were reweighted to account for the sampling design. Childhood overweight and obesity prevalence were calculated using International Obesity Taskforce definitions. Multinomial logistic regression examined the association between parent weight status, indicators of SES and child weight. Overall, 25% of children were either overweight (19.3%) or obese (6.6%). Parental obesity was a significant predictor of child obesity. Of children with normal weight parents, 14.4% were overweight or obese whereas 46.2% of children with obese parents were overweight or obese. Maternal education and household class were more consistently associated with a child being in a higher body mass index category than household income. Adjusted regression indicated that female gender, one parent family type, lower maternal education, lower household class and a heavier parent weight status significantly increased the odds of childhood obesity. Conclusions/Significance: Parental weight appears to be the most influential factor driving the childhood obesity epidemic in Ireland and is an independent predictor of child obesity across SES groups. Due to the high prevalence of obesity in parents and children, population based interventions are required.
