  Title Mesenchymal/proangiogenic factor YKL-40 related to glioblastomas and its relationship with the subventricular zone Type Journal Article
  Year 2017 Publication Folia Neuropathologica Abbreviated Journal Folia Neuropathol  
  Volume 55 Issue 1 Pages 14-22  
  Keywords (down) Ykl-40; glioblastoma; glioblastoma stem cells; subventricular zone  
  Abstract <i>Glioblastoma is the most common primary brain tumor. Despite multimodality therapy with aggressive microsurgical resection and adjuvant chemotherapy and radiotherapy, the median survival is below 15 months. Glioblastomas are heterogeneous tumors with high resistance to most chemotherapeutic drugs. According to reliable evidence, YKL-40, one of the best investigated chitinase-like protein, may facilitate invasion, migration and angiogenesis, and could be also responsible for temozolomide resistance in glioblastoma, thus conferring a dismal prognosis. Previous studies have demonstrated that glioblastoma stem cells give rise to endothelial cells through an YKL-40 influence. Such factor is closely related to the subventricular zone. This review focuses on the most recent theories involving the possible relationship between topographic gliomagenesis related to the subventricular zone and YKL-40.</i>.

  Title A system to evaluate fire impacts from simulated fire behavior in Mediterranean areas of Central Chile Type Journal Article
  Year 2017 Publication The Science of the Total Environment Abbreviated Journal Sci Total Environ  
  Volume 579 Issue Pages 1410-1418  
  Keywords (down) Wildfire behavior; Wildfire intensity; Wildfire simulation  
  Abstract Wildfires constitute the greatest economic disruption to Mediterranean ecosystems, from a socio-economic and ecological perspective (Molina et al., 2014). This study proposes to classify fire intensity levels based on potential fire behavior in different types of Mediterranean vegetation types, using two geographical scales. The study considered >4 thousand wildfires over a period of 25years, identifying fire behavior on each event, based on simulations using “KITRAL”, a model developed in Chile in 1993 and currently used in the entire country. Fire intensity values allowed results to be classified into six fire effects categories (levels), each of them with field indicators linking energy values with damage related to burned vegetation and wildland urban interface zone. These indicators also facilitated a preliminary assessment of wildfire impact on different Mediterranean land uses and, are therefore, a useful tool to prioritize future interventions.

  Title The novel long non-coding RNA TALNEC2, regulates tumor cell growth and the stemness and radiation response of glioma stem cells Type Journal Article
  Year 2017 Publication Oncotarget Abbreviated Journal Oncotarget  
  Volume 8 Issue 19 Pages 31785-31801  
  Keywords (down) Talnec2; glioblastoma; glioma stem cells; long non-cording RNAs; mesenchymal transformation  
  Abstract Despite advances in novel therapeutic approaches for the treatment of glioblastoma (GBM), the median survival of 12-14 months has not changed significantly. Therefore, there is an imperative need to identify molecular mechanisms that play a role in patient survival. Here, we analyzed the expression and functions of a novel lncRNA, TALNEC2 that was identified using RNA seq of E2F1-regulated lncRNAs. TALNEC2 was localized to the cytosol and its expression was E2F1-regulated and cell-cycle dependent. TALNEC2 was highly expressed in GBM with poor prognosis, in GBM specimens derived from short-term survivors and in glioma cells and glioma stem cells (GSCs). Silencing of TALNEC2 inhibited cell proliferation and arrested the cells in the G1\S phase of the cell cycle in various cancer cell lines. In addition, silencing of TALNEC2 decreased the self-renewal and mesenchymal transformation of GSCs, increased sensitivity of these cells to radiation and prolonged survival of mice bearing GSC-derived xenografts. Using miRNA array analysis, we identified specific miRNAs that were altered in the silenced cells that were associated with cell-cycle progression, proliferation and mesenchymal transformation. Two of the downregulated miRNAs, miR-21 and miR-191, mediated some of TALNEC2 effects on the stemness and mesenchymal transformation of GSCs. In conclusion, we identified a novel E2F1-regulated lncRNA that is highly expressed in GBM and in tumors from patients of short-term survival. The expression of TALNEC2 is associated with the increased tumorigenic potential of GSCs and their resistance to radiation. We conclude that TALNEC2 is an attractive therapeutic target for the treatment of GBM.

  Title Impact on Area-Level Physical Activity Following the Implementation of a Fitness Zone in Montevideo, Uruguay Type Journal Article
  Year 2017 Publication Journal of Physical Activity & Health Abbreviated Journal J Phys Act Health  
  Volume 14 Issue 11 Pages 883-887  
  Keywords (down) Soparc; observation; parks  
  Abstract BACKGROUND: The aim of the study was to measure the level of physical activity (PA) of the users of an urban park before and after the installation of 2 fitness zones (FZs) and to assess the impact of that intervention on the users' level of PA. METHODS: The System for Observing Play and Recreation in Communities method was applied in the urban plaza Liber Seregni in Montevideo (Uruguay): 14 different areas were mapped and then recategorized as fitness (for PAs, including sports), green, and paved zones. Observations were made in the spring (Sep-Oct) of 2011 and 2014, before and after placing 2 FZs. Participation was analyzed by gender, year, mapped areas, and zones, and significant differences were assessed using the chi2 test. RESULTS: In total, 7342 individuals (4091 men and 3251 women) were observed. A greater number of people with intense PA could be seen in the FZ, with significant differences between 2011 (45%) and 2014 (70%; P < .05). CONCLUSION: This is the first longitudinal study on the impact of an intervention to increase the level of PA in public spaces in Uruguay. Higher intensity levels of PA and fewer sedentary people were observed after the installation of the FZ.

  Title Developing local health policy: Profiling needs and opportunities in the Municipality of Quito, Ecuador Type Journal Article
  Year 2017 Publication Journal of Public Health Policy Abbreviated Journal J Public Health Policy  
  Volume Issue Pages  
  Keywords (down) Quito; local health policy; municipality; policy development; public health  
  Abstract We describe the steps taken and analysis applied in developing a local health policy agenda for the city of Quito, in Ecuador. In 2014, the Health Commissioner's Office of the Municipality of Quito analyzed the city's epidemiological health profiles, social determinants of health, the legal authority of the Municipality, and relevant literature to understand the city's health burden and develop a Ten-Year Health Plan (2015-2025). Results revealed that Quito's population suffered from noncommunicable chronic diseases (diabetes and hypertension) and identified the primary risk factors (poor nutrition, physical inactivity, and resulting overweight or obesity). Other common conditions included respiratory diseases, mental health conditions, deaths and injuries from motor vehicles, violence, and physical insecurity. The plan emphasized health promotion and disease prevention with the aim of transforming citizens' health perceptions with their active participation by fostering public and private intersectoral commitment to improve the quality of life of the population .
