Charged-particle nuclear modification factors in PbPb and pPb collisions at √=sNN=5.02 TeV

The spectra of charged particles produced within the pseudorapidity window |η| < 1 at √ sNN = 5.02 TeV are measured using 404 µb −1 of PbPb and 27.4 pb−1 of pp data collected by the CMS detector at the LHC in 2015. The spectra are presented over the transverse momentum ranges spanning 0.5 < pT < 400 GeV in pp and 0.7 < pT < 400 GeV in PbPb collisions. The corresponding nuclear modification factor, RAA, is measured in bins of collision centrality. The RAA in the 5% most central collisions shows a maximal suppression by a factor of 7–8 in the pT region of 6–9 GeV. This dip is followed by an increase, which continues up to the highest pT measured, and approaches unity in the vicinity of pT = 200 GeV. The RAA is compared to theoretical predictions and earlier experimental results at lower collision energies. The newly measured pp spectrum is combined with the pPb spectrum previously published by the CMS collaboration to construct the pPb nuclear modification factor, RpA, up to 120 GeV. For pT > 20 GeV, RpA exhibits weak momentum dependence and shows a moderate enhancement above unity

Crossing spatial analyses and livestock economics to understand deforestation processes in the Brazilian Amazon: the case of Sao Felix do Xingu in South Para

The Amazon is the largest tropical forest area on earth, and has been undergoing rapid deforestation for the last four decades. In the Brazilian Amazon, large-scale pasture for cattle ranching and soybean production are the main land uses, leading to a yearly deforestation rate of 0.5%. These conversions are mostly located in frontier areas distributed along the so-called "arc of deforestation". Within this large zone, various land use change processes are interacting through several modes of land valuation and organisation. From several case studies in the State of Pará (Brazil), the current project aims at analysing how landscape dynamics are related to infrastructure development, ecological conditions, zoning policies and to the evolution and the organisation of the production, consumption and marketing chains of livestock products. This paper presents the results for one test site, the region of São Félix do Xingú, South of Pará. This region is the focus of land speculation, cattle expansion, and deforestation. Road construction, investments in electrical energy, financial credit for cattle, and the land reform policies have all fuelled this process. All these factors make this region one of the most dynamic agricultural frontiers in the Brazilian Amazon. The main objective of the paper is to improve our understanding of deforestation processes by crossing spatial analyses and livestock economics studies, and to characterise the role and impact of various natural and anthropic factors in the location and development of the main types of farmers, and their policy implications

Prevalence and predictors of posttraumatic stress disorder in adult survivors of childhood cancer.

OBJECTIVE: Recent studies have found that a subset of young adult survivors of childhood cancer report posttraumatic stress symptoms in response to their diagnosis and treatment. However, it is unclear if these symptoms are associated with impairment in daily functions and/or significant distress, thereby resulting in a clinical disorder. Furthermore, it is unknown whether this disorder continues into very long-term survivorship, including the 3(rd) and 4(th) decades of life. This study hypothesized that very long-term survivors of childhood cancer would be more likely to report symptoms of posttraumatic stress disorder, with functional impairment and/or clinical distress, compared to a group of healthy siblings. PATIENTS AND METHODS: 6,542 childhood cancer survivors over the age of 18 who were diagnosed between 1970 and 1986 and 368 siblings of cancer survivors completed a comprehensive demographic and health survey. RESULTS: 589 survivors (9%) and 8 siblings (2%) reported functional impairment and/or clinical distress in addition to the set of symptoms consistent with a full diagnosis of Posttraumatic Stress Disorder (PTSD). Survivors had more than a four-fold risk of PTSD compared to siblings (OR=4.14, 95%CI: 2.08-8.25). Controlling for demographic and treatment variables, increased risk of PTSD was associated with educational level of high school or less (OR=1.51, 95% CI=1.16-1.98), being unmarried (OR=1.99, 95% CI=1.58-2.50), annual income less than $20,000 (OR=1.63, 95% CI=1.21-2.20), and being unemployed (OR=2.01, 95% CI=1.62-2.51). Intensive treatment was also associated with increased risk of full PTSD (OR=1.36, 95% CI 1.06 -1.74). CONCLUSIONS: Posttraumatic stress disorder is reported significantly more often by childhood cancer survivors than by sibling controls. Although most survivors are apparently doing well, a subset report significant impairment that may warrant targeted intervention

Drosophila melanogaster as a model organism for bluetongue virus replication and tropism

Bluetongue virus (BTV) is the etiological agent of bluetongue (BT), a hemorrhagic disease of ruminants that can cause high levels of morbidity and mortality. BTV is an arbovirus transmitted between its ruminant hosts by Culicoides biting midges (Diptera: Ceratopogonidae). Recently, Europe has experienced some of the largest BT outbreaks ever recorded, including areas with no known history of the disease, leading to unprecedented economic and animal welfare issues. The current lack of genomic resources and genetic tools for Culicoides restricts any detailed study of the mechanisms involved in the virus-insect interactions. In contrast, the genome of the fruit fly (Drosophila melanogaster) has been successfully sequenced, and it is used extensively as a model of molecular pathways due to the existence of powerful genetic technology. In this study, D. melanogaster is investigated as a model for the replication and tropism of BTV. Using reverse genetics, a modified BTV-1 that expresses the fluorescent mCherry protein fused to the viral nonstructural protein NS3 (BTV-1/NS3mCherry) was generated. We demonstrate that BTV-1/NS3mCherry is not only replication competent as it retains many characteristics of the wild-type virus but also replicates efficiently in D. melanogaster after removal of the bacterial endosymbiont Wolbachia pipientis by antibiotic treatment. Furthermore, confocal microscopy shows that the tissue tropism of BTV-1/NS3mCherry in D. melanogaster resembles that described previously for BTV in Culicoides. Overall, the data presented in this study demonstrate the feasibility of using D. melanogaster as a genetic model to investigate BTV-insect interactions that cannot be otherwise addressed in vector species
