2 nd Brazilian Consensus on Chagas Disease, 2015

Abstract Chagas disease is a neglected chronic condition with a high burden of morbidity and mortality. It has considerable psychological, social, and economic impacts. The disease represents a significant public health issue in Brazil, with different regional patterns. This document presents the evidence that resulted in the Brazilian Consensus on Chagas Disease. The objective was to review and standardize strategies for diagnosis, treatment, prevention, and control of Chagas disease in the country, based on the available scientific evidence. The consensus is based on the articulation and strategic contribution of renowned Brazilian experts with knowledge and experience on various aspects of the disease. It is the result of a close collaboration between the Brazilian Society of Tropical Medicine and the Ministry of Health. It is hoped that this document will strengthen the development of integrated actions against Chagas disease in the country, focusing on epidemiology, management, comprehensive care (including families and communities), communication, information, education, and research

An update of the Worldwide Integrated Assessment (WIA) on systemic insecticides. Part 2: impacts on organisms and ecosystems

New information on the lethal and sublethal effects of neonicotinoids and fipronil on organisms is presented in this review, complementing the previous WIA in 2015. The high toxicity of these systemic insecticides to invertebrates has been confirmed and expanded to include more species and compounds. Most of the recent research has focused on bees and the sublethal and ecological impacts these insecticides have on pollinators. Toxic effects on other invertebrate taxa also covered predatory and parasitoid natural enemies and aquatic arthropods. Little, while not much new information has been gathered on soil organisms. The impact on marine coastal ecosystems is still largely uncharted. The chronic lethality of neonicotinoids to insects and crustaceans, and the strengthened evidence that these chemicals also impair the immune system and reproduction, highlights the dangers of this particular insecticidal classneonicotinoids and fipronil. , withContinued large scale – mostly prophylactic – use of these persistent organochlorine pesticides has the potential to greatly decreasecompletely eliminate populations of arthropods in both terrestrial and aquatic environments. Sublethal effects on fish, reptiles, frogs, birds and mammals are also reported, showing a better understanding of the mechanisms of toxicity of these insecticides in vertebrates, and their deleterious impacts on growth, reproduction and neurobehaviour of most of the species tested. This review concludes with a summary of impacts on the ecosystem services and functioning, particularly on pollination, soil biota and aquatic invertebrate communities, thus reinforcing the previous WIA conclusions (van der Sluijs et al. 2015)

Low-cost automatic station for compost temperature monitoring

ABSTRACT Temperature monitoring is an important procedure to control the composting process. Due to cost limitation, temperature monitoring is manual and with daily sampling resolution. The objective of this study was to develop an automatic station with US$ 150 dollars, able to monitor air temperature at two different points in a compost pile, with a 5-min time resolution. In the calibration test, the sensors showed an estimated uncertainty from ± 1 to ± 1.9 ºC. In the field validation test, the station guaranteed secure autonomy for seven days and endured high humidity and extreme temperature (> 70 °C)

Evaluation of Collagen Fibers, MMP2, MMP9, 8-OHdG and Apoptosis in the Aorta of Ovariectomized LDL Knockout Mice Submitted to Aerobic Exercise

Abstract Background: In menopause, there is greater cellular exposure to oxidative stress, related to the decreased antioxidative effects of estrogen. These metabolic changes favor the progression of cardiovascular diseases, such as atherosclerosis. Abnormal function of the aorta - the most important artery - is associated with many cardiovascular diseases. Collagen, especially types I and III, is one of the most important aortic wall components and it can be affected by many factors, including menopause. The 8-OHdG is one of the main markers of DNA oxidative damage induced by reactive oxygen species (ROS). Objective: We aimed to investigate effects of moderate aerobic training on the ascending aorta of LDL-knockout (LDL-KO) and ovariectomized female mice. Methods: A total of 15 C57BL/6 mice and 15 LDL-KO mice were divided into experimental groups. The thickness and volume density of types I and III collagen fibers were performed by morphoquantitative analysis, whereas the MMP-2 and MMP-9 and 8-OHdG were detected by immunohistochemistry and apoptosis was detected by the TUNEL assay. The significance level for all tests was p < 0.05. Results: Exercise causes an increase in the thickness of the aorta in LDL-KO groups, particularly accentuated in the ovariectomized groups. The type I collagen fibers showed an increase in volume density influenced by training in both Control groups and in the LDL-KO group. Type III collagen density decreased in both groups. The MMP-2 showed moderade immunostaining in the tunica media in LDL-KO groups, which did not occur in the control groups and the MMP-9 stained irregularly in all tissues. The marker 8-OhdG was stronger in the exercise training groups. Additionally, the ovariectomy, the exercise training and the LDL-KO treatments increased apoptosis. Conclusion: These results suggest that moderate-intensity aerobic exercise in ovariectomized mice associated to an increase in LDL rate possibly increases oxidative stress and apoptosis induction

Sistema de recomendação de fertilizantes e corretivos para a cultura do abacaxi - fertcalc-abacaxi Fertilizer and lime recommendation system for pineapple - fertcalc-abacaxi

A demanda nutricional do abacaxizeiro é alta em relação à de outras culturas e depende do cultivar, do peso do fruto, do destino da produção, do sistema e da densidade de plantio, e a variação desses fatores nem sempre está contemplada nas tabelas de adubação. O objetivo deste trabalho foi propor um Sistema de Recomendação de Fertilizantes e Corretivos para a Cultura do Abacaxi (FERTCALC-Abacaxi), elaborado a partir da sistematização e modelagem de informações de literatura e do conhecimento atual sobre adubação e nutrição mineral da cultura. O FERTCALC-Abacaxi baseia-se no método do balanço nutricional e está subdividido em dois subsistemas: o subsistema requerimento, que contempla a demanda pela planta, considerando a eficiência de recuperação dos nutrientes aplicados e uma dose para atender o critério de "sustentabilidade", e o subsistema suprimento, que compreende a oferta de nutrientes pela calagem, pelo solo, pela matéria orgânica e pelos resíduos orgânicos. Simulações realizadas com o FERTCALC-Abacaxi mostraram que o Sistema recomenda maiores doses para o cultivar Pérola em relação ao Smooth Cayenne, para plantios mais adensados e para obtenção de frutos mais pesados. Diferentemente das tabelas, as doses variaram de forma contínua com a produtividade esperada e com o teor de nutrientes no solo, sendo maiores no primeiro em relação ao segundo cultivo. Por contemplar na sua estrutura maior número de fatores envolvidos na resposta da cultura à adubação, a exemplo da produtividade esperada, do cultivar, do peso do fruto, do sistema e da densidade de plantio, e considerar a contribuição dos resíduos orgânicos do cultivo anterior, o FERTCALC-Abacaxi constitui-se numa alternativa mais versátil para recomendar doses de fertilizantes e corretivos para o abacaxizeiro, embora precise ser aperfeiçoado em futuras versões e ter seu desempenho avaliado em condições práticas.<br>The nutritional demand of pineapple plants is higher than for other crops and IT depends on cultivar, fruit weight, production destination and planting density and cultivation system. However, the variation in these factors is not always taken into account in fertilization tables. The purpose of this study was to propose a fertilizer and lime recommendation system for pineapple designated FERTCALC-Abacaxi, based on systematization and modeling of literature data and the current knowledge concerning fertilization and mineral nutrition of the crop. FERTCALC-Abacaxi is based on the nutritional balance method and is divided into two subsystems: the requirement subsystem that contemplates the plant demand, considering the efficiency of recovery of the applied nutrients and a dose to meet the requirement "sustainability"; and the supply subsystem that comprises the nutrient supply by liming, soil, organic matter, and by organic residues. Simulations with FERTCALC-Abacaxi showed that the System recommends higher doses for the Pérola cv., than for Smooth Cayenne, for denser planting systems and to obtain heavier fruits; and differently from the tables, it varied continuously with the expected productivity and soil nutrient contents, being higher in the first than in the second growing cycle. In view of the higher number of factors taken into consideration that reflect the response of the crop to fertilization, for example the expected yield, cultivar, fruit weight, planting density and system, besides taking into account the contribution of organic residues from the previous cycle, the FERTCALC- Abacaxi represents a more versatile alternative for fertilizer and lime recommendation for the pineapple crop. However, improvements in future versions of the System as well as its validation under practical conditions are necessary
