The Australian experience of World Wide Views on global warming: The first global deliberation process

World Wide Views on Global Warming was the first ever global-scale citizen deliberation process, held on 25-26 September 2009 and involving approximately 4,000 citizens in 38 countries. WWViews sought to provide citizens with a voice in the 2009 UN Climate Summit in Copenhagen (COP15) by engaging them in a deliberative process about global political positions on climate change. The process produced clear, comparable results across all participating countries that were given to COP15 negotiators. The Danish Government agencies, the Danish Board of Technology and the Danish Cultural Institute, initiated the global process. Organisers in each participating country ran events using the same standardised process. The University of Technology Sydney, the organisers of the Australian WWViews event, paid special attention to several elements of the process to maximise participation and impact within the local context. This paper outlines the standardised global process used for this deliberative event and describes and reflects upon the tailored approaches developed for Australia. It examines in detail the objectives, processes and outcomes of recruiting and supporting participants and recruiting, training and coordinating facilitators, communications and dissemination of results and specific features of the Australian event. It includes the organisers' reflections on success factors, challenges and surprises, as well as feedback from facilitators and participants. This paper concludes with a number of critical questions arising from the Australian experience of World Wide Views on Global Warming that are pertinent for practitioners designing other deliberative forums and particularly anyone concerned about future prospects for global deliberative democracy.

Local perspectives on weirs in the Upper Nepean

The Independent Expert Panel of the HawkesburyâNepean River Management Forum commissioned the Institute for Sustainable Futures to conduct research into the values held by river users and community members in relation to the weirs on the Upper Nepean River and concerns they would have with any change to the current situation. The weirs at the centre of this research are Bergins, Thurns, Sharpes and Brownlow Hill. The research questions guiding the project are: What is the nature of the social and economic relationship between people and weirs at a local level In what ways would people want to participate in decisions about the weirs and river management Local people were asked about how they use the weirs, what value they see the weirs having for their community, culture and industry and what concerns there may be about potential changes. The research aims to help the Expert Panel and the Forum make appropriate decisions about potential retention, modification or removal of the weirs and the fishways associated with them. A further aim is to facilitate public participation in the decision-making process. Within any community, there are different individuals and groups with diverse interests and experiences. These differences might result in multiple perspectives between and within groups. To differentiate some of these perspectives, the broader community was divided into four sectors: general public, community groups, identifiable water users such as irrigators and recreational users and Indigenous groups. The general public participants emphasised the aesthetic and leisure value of the river. They appear to identify very strongly with the river, with participants interpreting the existence of the weirs as integral to both the riverâs survival and the ongoing economic survival of the region. The findings indicate that this group view the weirs as an integral part of the river and the river as an integral part of the Camden community

A consensus research agenda for optimising nasal drug delivery

Nasal drug delivery has specific challenges which are distinct from oral inhalation, alongside which it is often considered. The next generation of nasal products will be required to deliver new classes of molecule, e.g. vaccines, biologics and drugs with action in the brain or sinuses, to local and systemic therapeutic targets. Innovations and new tools/knowledge are required to design products to deliver these therapeutic agents to the right target at the right time in the right patients. We report the outcomes of an expert meeting convened to consider gaps in knowledge and unmet research needs in terms of (i) formulation and devices, (ii) meaningful product characterization and modeling, (iii) opportunities to modify absorption and clearance. Important research questions were identified in the areas of device and formulation innovation, critical quality attributes for different nasal products, development of nasal casts for drug deposition studies, improved experimental models, the use of simulations and nasal delivery in special populations. We offer these questions as a stimulus to research and suggest that they might be addressed most effectively by collaborative research endeavors

Aérosols de médicaments

L\u27aérosolthérapie a bénéficié ces dernières années de progrès technologiques considérables au niveau des générateurs d\u27aérosols. Les aérosols doseurs liquides HFA avec ou sans chambre d\u27inhalation, les aérosols doseurs de poudre ont vu leurs indications respectives précisées. Les systèmes de nébulisation ont également progressé avec notamment l\u27apparition des nébuliseurs à membranes. La nébulisation permet de traiter les formes les plus sévères des maladies repiratoires, asthme, BPCO, mucoviscidose, par les bronchodilatateurs, les corticoïdes, les antibiotiques et la rhDNase I. L\u27utilisation de la nébulisation trouve depuis peu des applications pour le traitement de maladies systémiques telles que le diabète ou l\u27hypertension artérielle pulmonaire. Des perspectives apparaissent également pour la chimiothérapie antitumorale et la vaccination par aérosols. Les conditions optimales de prescription, d\u27administration et de suivi de l\u27aérosolthérapie ont été définies

The Mitochondrial Ca(2+) Uniporter: Structure, Function, and Pharmacology.

Mitochondrial Ca(2+) uptake is crucial for an array of cellular functions while an imbalance can elicit cell death. In this chapter, we briefly reviewed the various modes of mitochondrial Ca(2+) uptake and our current understanding of mitochondrial Ca(2+) homeostasis in regards to cell physiology and pathophysiology. Further, this chapter focuses on the molecular identities, intracellular regulators as well as the pharmacology of mitochondrial Ca(2+) uniporter complex

Mitochondrial Morphogenesis, Dendrite Development, and Synapse Formation in Cerebellum Require both Bcl-w and the Glutamate Receptor δ2

Bcl-w belongs to the prosurvival group of the Bcl-2 family, while the glutamate receptor δ2 (Grid2) is an excitatory receptor that is specifically expressed in Purkinje cells, and required for Purkinje cell synapse formation. A recently published result as well as our own findings have shown that Bcl-w can physically interact with an autophagy protein, Beclin1, which in turn has been shown previously to form a protein complex with the intracellular domain of Grid2 and an adaptor protein, nPIST. This suggests that Bcl-w and Grid2 might interact genetically to regulate mitochondria, autophagy, and neuronal function. In this study, we investigated this genetic interaction of Bcl-w and Grid2 through analysis of single and double mutant mice of these two proteins using a combination of histological and behavior tests. It was found that Bcl-w does not control the cell number in mouse brain, but promotes what is likely to be the mitochondrial fission in Purkinje cell dendrites, and is required for synapse formation and motor learning in cerebellum, and that Grid2 has similar phenotypes. Mice carrying the double mutations of these two genes had synergistic effects including extremely long mitochondria in Purkinje cell dendrites, and strongly aberrant Purkinje cell dendrites, spines, and synapses, and severely ataxic behavior. Bcl-w and Grid2 mutations were not found to influence the basal autophagy that is required for Purkinje cell survival, thus resulting in these phenotypes. Our results demonstrate that Bcl-w and Grid2 are two critical proteins acting in distinct pathways to regulate mitochondrial morphogenesis and control Purkinje cell dendrite development and synapse formation. We propose that the mitochondrial fission occurring during neuronal growth might be critically important for dendrite development and synapse formation, and that it can be regulated coordinately by multiple pathways including Bcl-2 and glutamate receptor family members

In vitro epigenetic reprogramming of human cardiac mesenchymal stromal cells into functionally competent cardiovascular precursors

Adult human cardiac mesenchymal-like stromal cells (CStC) represent a relatively accessible cell type useful for therapy. In this light, their conversion into cardiovascular precursors represents a potential successful strategy for cardiac repair. The aim of the present work was to reprogram CStC into functionally competent cardiovascular precursors using epigenetically active small molecules. CStC were exposed to low serum (5% FBS) in the presence of 5 \ub5M all-trans Retinoic Acid (ATRA), 5 \ub5M Phenyl Butyrate (PB), and 200 \ub5M diethylenetriamine/nitric oxide (DETA/NO), to create a novel epigenetically active cocktail (EpiC). Upon treatment the expression of markers typical of cardiac resident stem cells such as c-Kit and MDR-1 were up-regulated, together with the expression of a number of cardiovascular-associated genes including KDR, GATA6, Nkx2.5, GATA4, HCN4, NaV1.5, and \u3b1-MHC. In addition, profiling analysis revealed that a significant number of microRNA involved in cardiomyocyte biology and cell differentiation/proliferation, including miR 133a, 210 and 34a, were up-regulated. Remarkably, almost 45% of EpiC-treated cells exhibited a TTX-sensitive sodium current and, to a lower extent in a few cells, also the pacemaker I(f) current. Mechanistically, the exposure to EpiC treatment introduced global histone modifications, characterized by increased levels of H3K4Me3 and H4K16Ac, as well as reduced H4K20Me3 and H3s10P, a pattern compatible with reduced proliferation and chromatin relaxation. Consistently, ChIP experiments performed with H3K4me3 or H3s10P histone modifications revealed the presence of a specific EpiC-dependent pattern in c-Kit, MDR-1, and Nkx2.5 promoter regions, possibly contributing to their modified expression. Taken together, these data indicate that CStC may be epigenetically reprogrammed to acquire molecular and biological properties associated with competent cardiovascular precursors
