Abstract: To evaluate the effect of plant extracts on the growth of Colletotrichum gloeosporioides, ethanolic extractsfrom pitomba seeds, plantain, sword-of-saint-george and maigoya leaves were obtained and incorporated inpotato-dextrose-agar medium (PDA) at concentrations of 1%, 5% and 10% (v/v). Micelial growth wasevaluated in these media. The results demonstrated the inhibitory effect of extracts from plantain andpitomba increase significantly at concentrations above 5% (v/v), causing almost complete inhibition of thefungal growth (90% and 100%, respectively). In contrast, maigoya and sword-of-saint-george extractsshowed small inhibition even at a concentration of 10% (v/v), causing a reduction, in the fungal growth, ofonly 8% and 23%, respectively. The fungitoxic activity detected in the extracts tested in this work show thepotential usage as biopreservers of papaya, preventing contamination and consequent loss of fruits duringpostharvest.
Tussen wal en schip: Wat moet er gebeuren om schuldenaren met meervoudige problematiek te helpen?

Abstract: In this study we focus on debtors with multiple problems. While this group has grown in recent years, the possibilities to settle their debts have decreased. The requirements to qualify for debt counselling are too high, there are too many rules and creditors do not cooperate. This results in an increase in the number of evictions and homeless people. Shelters become clogged and the pressure on care workers grows. Several local initiatives tackle the problem of debtors with multiple problems. And the NVVK develops new guidelines for debt counselling. We recommend attention to prevention, less barriers at debt counselling and an integral approach.

Thymocyte migration: an affair of multiple cellular interactions?
Savino W.,Ayres Martins S.,Neves-dos-Santos S.,Smaniotto S.
Brazilian Journal of Medical and Biological Research , 2003,
Abstract: Cell migration is a crucial event in the general process of thymocyte differentiation. The cellular interactions involved in the control of this migration are beginning to be defined. At least chemokines and extracellular matrix proteins appear to be part of the game. Cells of the thymic microenvironment produce these two groups of molecules, whereas developing thymocytes express the corresponding receptors. Moreover, although chemokines and extracellular matrix can drive thymocyte migration per se, a combined role for these molecules appears to contribute to the resulting migration patterns of thymocytes in their various stages of differentiation. The dynamics of chemokine and extracellular matrix production and degradation is not yet well understood. However, matrix metalloproteinases are likely to play a role in the breakdown of intrathymic extracellular matrix contents. Thus, the physiological migration of thymocytes should be envisioned as a resulting vector of multiple, simultaneous and/or sequential stimuli involving chemokines, adhesive and de-adhesive extracellular matrix proteins, as well as matrix metalloproteinases. Accordingly, it is conceivable that any pathological change in any of these loops may result in the alteration of normal thymocyte migration. This seems to be the case in murine infection by the protozoan parasite Trypanosoma cruzi, the causative agent of Chagas' disease. A better knowledge of the physiological mechanisms governing thymocyte migration will provide new clues for designing therapeutic strategies targeting developing T cells.

Abstract: The study characterized the sites and the behavior of the forest species Acacia mangium Willd; Inga uruguensis Hook& Arn; Syzygium jambolanum (Lam.) DC. and Tapirira guianensis Aubl; in a gully in Nazareno county, MG. To understand thebehavior of the forest species analyzed with the respective environmental variables of each site was also envisaged. Aiming tocharacterize the sites, the slopes of the gullies were stratified into lower, medium and upper gradients, for which analyses in the soilsfor the variables: physicochemical and moisture were performed. The monitoring of the development of the species was done by meansof the measures of total height, soil height stem circumference and crown area. Four measurements were accomplished at 20, 25, 28and 31 months of age. The statistical program R was employed for the statistical analysis. The lower, medium and upper gradientspresented soils of poor fertility in the six areas studied. On the average, the lower gradient presented greatest soil moisture followedby the medium and upper gradients. Acacia mangium and Inga uruguensis showed greatest growth in the period of the study, whileSyzygium jambolanum and Tapirira guianensis did not stand out for the studied environments. Acacia mangium presented bestgrowth in the mesic sites and Inga uruguensis stood out in the moist sites, showing a positive relationship between moisture contentand growth.

Abstract: The City Department of Environment and Sustainable Development (SEMADES, acronym in portuguese)has paid special attention to the monitoring of the environmental quality, mainly in the monitoring ofactivities that have high polluting potential. So, this work aims to avaluate the application of geotechnologies as a tool in the taking of decisions at the management and environmental monitoringof gas stations located at the Municipal District of Campo Grande - MS. For such, a spatialization ofthe gas station was made and the environmetal conditions of each gas station were surveyed, Alsocrossings with the hydrography, Areas of Permanent Preservation (APP) and the Geotechnical letter ofthe Municipal District have been carried through. The results had demonstrated that the usedgeoprocessing techniques will be able to assist the SEMADES at the control, monitoring and taking ofdecision in the Environmental licensing of gas stations, this can also be applied to other licensedactivities.
Qilin Is Essential for Cilia Assembly and Normal Kidney Development in Zebrafish
Jade Li, Zhaoxia Sun
PLOS ONE , 2011, DOI: 10.1371/journal.pone.0027365
Abstract: Defects in the cilium, a once thought vestigial organelle, have recently been implicated in many human diseases, including a number of cystic kidney diseases such as polycystic kidney disease (PKD), Bardet Bieldl Syndrome, and Meckel-Gruber Syndrome. In a forward genetic screen, qilin was identified as a novel gene important in the pathogenesis of kidney cysts in zebrafish. In this paper we characterized qilinhi3959A mutant's phenotypes in detail, investigated cilia formation in this mutant and performed structural and functional analysis of the Qilin protein. Results reveal Qilin's essential role in cilia assembly and maintenance in multiple organs, including the kidney, the lateral line organ, and the outer segment of the photoreceptor cell. In addition, rescue experiments suggest that defective pronephric cilia correlate with the formation of kidney cysts in qilinhi3959A mutants. Further, genetic analysis suggests that qilin interacts with multiple intraflagellar transport (IFT) complex B genes, which is supported by the striking phenotypic similarities between qilinhi3959A and IFT complex B mutants. Finally, through deletion analysis we provide evidence that the well-conserved N-terminus and the coiled-coil domain of Qilin are both essential and sufficient for its function. Taken all the observations together, we propose that Qilin acts in a similar role as IFT complex B proteins in cilia assembly, maintenance and kidney development in zebrafish.
Global Deliberative Democracy and Climate Change: Insights from World Wide Views on Global Warming in Australia

PORTAL : Journal of Multidisciplinary International Studies , 2011,
Abstract: On 26 September 2009, approximately 4,000 citizens in 38 countries participated in World Wide Views on Global Warming (WWViews). WWViews was an ambitious first attempt to convene a deliberative mini-public at a global scale, giving people from around the world an opportunity to deliberate on international climate policy and to make recommendations to the decision-makers meeting at the United Nations Climate Change Conference in Copenhagen (COP-15) in December 2009. In this paper, we examine the role that deliberative mini-publics can play in facilitating the emergence of a global deliberative system for climate change response. We pursue this intent through a reflective evaluation of the Australian component of the World Wide Views on Global Warming project (WWViews). Our evaluation of WWViews is mixed. The Australian event was delivered with integrity and feedback from Australian participants was almost universally positive. Globally, WWViews demonstrated that it is feasible to convene a global mini-public to deliberate on issues of global relevance, such as climate change. On the other hand, the contribution of WWViews towards the emergence of a global deliberative system for climate change response was limited and it achieved little influence on global climate change policy. We identify lessons for future global mini-publics, including the need to prioritise the quality of deliberation and provide flexibility to respond to cultural and political contexts in different parts of the world. Future global mini-publics may be more influential if they seek to represent discourse diversity in addition to demographic profiles, use designs that maximise the potential for transmission from public to empowered space, run over longer time periods to build momentum for change and experiment with ways of bringing global citizens together in a single process instead of discrete national events.
The emergence of community strategic planning in New South Wales, Australia: Influences, challenges and opportunities
Jason Prior,Jade Herriman
Commonwealth Journal of Local Governance , 2010, DOI: 10.5130/cjlg.v0i7.1890
Abstract: This paper investigates the emergence of community strategic planning in the New South Wales (NSW) local government sector, against the backdrop of a series of broad influences ranging from increased interest in participatory democracy through to sustainable infrastructure provision. It provides an understanding of how community strategic planning has evolved over the past few decades to embody these influences. The paper concludes with reflections on some common challenges and opportunities experienced by local councils in NSW that have undertaken voluntary community strategic planning or are in the process of developing community strategic plans. Given underlying similarities in the emergence of participatory long-term strategic planning in local government around the world, many of the experiences associated with the preparation of community strategic plans in the NSW context are likely to be of relevance to those undertaking similar processes in other jurisdictions.
