Title Ethical challenges for international collaborative research partnerships in the context of the Zika outbreak in the Dominican Republic: a qualitative case study Type Journal Article
Year 2017 Publication Health Research Policy and Systems Abbreviated Journal Health Res Policy Syst
Volume 15 Issue 1 Pages 82
Keywords Capacity-building; Caribbean region; Developing countries; Disease outbreaks; Dominican Republic; Health equity; Health research systems; Research ethics; Research networks; Zika virus
Abstract BACKGROUND: The establishment of international collaborative research partnerships in times of infectious disease outbreaks of international importance has been considered an ethical imperative. Frail health research systems in low- and middle-income countries can be an obstacle to achieve the goal of knowledge generation and the search for health equity before, during and after infectious disease outbreaks. METHODS: A qualitative case study was conducted to identify the challenges and opportunities facing the Dominican Republic with regards to developing international collaborative research partnerships in the context of the Zika outbreak and its ethical implications. Researchers conducted 34 interviews (n = 30 individual; n = 4 group) with 39 participants (n = 23 males; n = 16 females) representing the government, universities, international donor agencies, non-governmental organisations, community-based organisations and medical societies, in two metropolitan cities. RESULTS: Five international collaborative research projects related to the Zika virus were identified. Major ethical challenges were linked to the governance of health research, training of human resources, the institutionalisation of scientific activity, access to research funds and cultural aspects. Capacity-building was not necessarily a component of some partnership agreements. With few exceptions, local researchers were merely participating in data collection and less on defining the problem. Opportunities for collaborative work included the possibility of participation in international research consortiums through calls for proposals. CONCLUSIONS: The Dominican government and research stakeholders can contribute to the international response to the Zika virus through active participation in international collaborative research partnerships; however, public recognition of the need to embrace health research as part of public policy efforts is warranted. A working group led by the government and formed by national and international research stakeholders will be key to identify ways in which the country could respond to the ethical demand of generating new knowledge in times of outbreaks.

Title Study of a tropical soil in order to use it to retain aluminum, iron, manganese and fluoride from acid mine drainage Type Journal Article
Year 2017 Publication Journal of Environmental Management Abbreviated Journal J Environ Manage
Volume 204 Issue Pt 1 Pages 563-570
Keywords Acid mine drainage; Column test; Contaminant transport; Liner; Tropical soils; Waste rock pile
Abstract The Ore Treatment Unit (UTM-Caldas), in the city of Caldas, Minas Gerais, Brazil, nowadays in decommissioning stage, was the first uranium extraction mine in Brazil. Several negative environmental impacts in the area have occurred, because of mining, treatment and beneficiation processes. Waste rock pile 4 (WRP-4) generates acid mine drainage (AMD), which is discharged in the Nestor Figueiredo retention pond (NFP). However, leakage of acid water by the NFP dam foundation has been constantly observed. Therefore, this research aimed to investigate a typical tropical soil, in order to use it as mineral liner for the NFP to minimize the leakage of acid water through the dam foundation and to retain predominant chemical species. Geotechnical, chemical and mineralogical tests were performed to characterize the soil and a column test was carried out using the acid mine drainage as contaminant, which contained aluminum (Al), manganese (Mn), iron (Fe) and fluoride (F-). The soil presented micro aggregation, acid pH, and low values of organic matter content and cation exchange capacity, which are characteristics of highly weathered soils. Diffusion was the predominant transport mechanism in the column test. Effluent solutions with pH less than 6.0 indicated the formation of insoluble Al-F complexes in the soil and desorption of iron and manganese at concentrations above those allowed by the Brazilian legislation. At pH greater than 6.0, the desorption of iron and manganese and release of aluminum and fluoride in the free form occurred, with concentrations also higher than the allowed by the Brazilian legislation.

Title Disaster Governance for Community Resilience in Coastal Towns: Chilean Case Studies Type Journal Article
Year 2017 Publication International Journal of Environmental Research and Public Health Abbreviated Journal Int J Environ Res Public Health
Volume 14 Issue 9 Pages
Keywords community resilience; disaster governance; tsunami
Abstract This study aimed to further our understanding of a characteristic of Community Resilience known as Disaster Governance. Three attributes of Disaster Governance-redundancy, diversity, and overlap-were studied in four coastal towns in southern Chile that are at risk of tsunamis. Overall, we explored how different spatial structures of human settlements influence Disaster Governance. Using the Projective Mapping Technique, the distribution of emergency institutions (N = 32) and uses given to specific sites (e.g., for refuge, sanitary purposes and medical attention) were mapped. Content and GIS analyses (Directional Distribution and Kernel Density Index) were used to explore the dispersion and concentration of institutions and uses in each town. Disaster Governance was found to be highly influenced by decisions taken during regional, urban, and emergency planning. Governance is better in towns of higher order in the communal hierarchical structure. Most of the emergency institutions were found to be located in central and urban areas, which, in turn, assures more redundancy, overlap, and diversity in governance in the event of a tsunami. Lack of flexibility of emergency plans also limits governance in rural and indigenous areas. While the spatial relationships found in this study indicate that urban sectors have better Disaster Governance than rural and indigenous sectors, the influence of resource availability after tsunamis, the role and responsibility of different levels of governments, and the politics of disaster also play an important role in Disaster Governance for determining Community Resilience. These findings shed light on emergency planning and aspects of the Disaster Management cycle.

Title CDK4/6 inhibition is more active against the glioblastoma proneural subtype Type Journal Article
Year 2017 Publication Oncotarget Abbreviated Journal Oncotarget
Volume 8 Issue 33 Pages 55319-55331
Keywords Cdk4/6; glioblastoma; mesenchymal; palbociclib; proneural
Abstract Glioblastoma (GBM) is the most common and lethal brain tumor. Gene expression profiling has classified GBM into distinct subtypes, including proneural, mesenchymal, and classical, and identifying therapeutic vulnerabilities of these subtypes is an extremely high priority. We leveraged The Cancer Genome Atlas (TCGA) data, in particular for microRNA expression, to seek druggable core pathways in GBM. The E2F1-regulated miR-17 92 cluster and its analogs are shown to be highly expressed in proneural GBM and in GSC lines, suggesting the E2F cell cycle pathway might be a key driver in proneural GBM. Consistently, CDK4/6 inhibition with palbociclib preferentially inhibited cell proliferation in vitro in a majority of proneural GSCs versus those of other subtypes. Palbociclib treatment significantly prolonged survival of mice with established intracranial xenografts of a proneural GSC line. We show that most of these sensitive PN GSCs expressed higher levels of CDK6 and had intact Rb1, while two GSC lines with CDK4 overexpression and null Rb1 were highly resistant to palbociclib. Importantly, palbociclib treatment of proneural GSCs upregulated mesenchymal-associated markers and downregulated proneural-associated markers, suggesting that CDK4/6 inhibition induced proneural-mesenchymal transition and underscoring the enhanced role of the E2F cell cycle pathway in the proneural subtype. Lastly, the combination of palbociclib and N,N-diethylaminobenzaldehyde, an inhibitor of the mesenchymal driver ALDH1A3, showed strong synergistic inhibitory effects against proneural GSC proliferation. Taken together, our results reveal that proneural GBM has increased vulnerability to CDK4/6 inhibition, and the proneural subtype undergoes dynamic reprogramming upon palbociclib treatment-suggesting the need for a combination therapeutic strategy.
