    Guarana plant is a native of the Amazon region. Due to its high amount of caffeine and tannins, the seed has medicinal and stimulating properties. The guarana industry has grown exponentially in recent years; however, little information is available about associated mycobiota, particularly endophytic fungi. The present study aimed to compare the distribution and diversity of endophytic fungi associated with the leaves and seeds of anthracnose-resistant and susceptible guarana plants produced in Maués and Manaus, Amazonas State, Brazil. A total of 7514 endophytic fungi were isolated on Potato Dextrose Agar, Sabouraud and Czapek media, and grouped into 77 morphological groups. Overall, fungal communities in guarana leaves and seeds were mainly composed by Colletotrichum and Fusarium genera, but also by Chondrostereum, Clonostachys, Curvularia, Hypomontagnella, Lentinus, Neopestalotiopsis, Nigrospora, Peroneutypa, Phyllosticta, Simplicillium and Tinctoporellus. Obtained results indicate that some members of Colletotrichum and Fusarium genera may have experienced dysbiosis during the guarana domestication process, suggesting that some individuals may behave as latent pathogens. The susceptible guarana genotype cultivated in Manaus presented higher fungal diversity. The relative abundance of taxa and diversity among samples suggests that communities are structured by genotype and geographic location. This is the first report of mycobiota in both guarana leaves and seeds.This research was funded by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior(CAPES) project Pró-Amazônia n◦3287/13.

    Background: Automobile accidents are increasing every day and are becoming a serious public health problem due to the high morbidity and mortality rate. The goal of the current study was to characterise the traffic accidents attended by the Mobile Emergency Care Service (MECS) in Ibiara, PB. Methods: This exploratory, descriptive, documentary study adopted a quantitative approach and analysis of data. The population consisted of all victims of traffic accidents attended by MECS in the city of Ibiara, PB, from June 2015 to June 2016. The following variables were studied: age, gender, time and day of the week the accident occurred, nature of the incident, substance ingested by the victim, wearing personal protective equipment (PPE) or not, the anatomical lesions on the victim and the body regions hit during the accident. Results: The sample consisted of 49 accident victims, and the majority (81.6%) were male, predominately 30 to 59 years. Events occurring at night (63.3%) and during the week (65.3%) predominated. The most frequent type of accident was motorcycle fall (71.4%), with almost half having consumed alcohol (46.9%) and most not wearing PPE (77.6%). The regions of the body most affected were the lower limbs (67.3%) and upper limbs (53.1%). Conclusion: The main factor/cause of these accidents was due to imprudence and violation of traffic laws, highlighting the need to invest in traffic education policies, to direct campaigns for the prevention of traffic accidents, as well as expand the surveillance of traffic laws by authorities

    O Acidente Vascular Encefálico (AVC) é um evento neurológico súbito, com um foco de isquemia ou hemorragia. Ambos, qualificados pelo déficit neurológico focal abrupto. Ressaltando, que estes déficits podem ocorrer, sendo a ocorrência espontânea, perduração de 15 minutos, autoresolutiva é denominada como Ataque Isquêmico Transitório (AIT), no entanto, toda insuficiência neural que não melhorar pós esse período deve ser manejado como AVC. O artigo objetivou descrever os principais aspectos clínicos do AVC. O AVC é uma emergência para a saúde pública, em razão de ser um potencial em gerar morbimortalidades para os portadores e prejuízos para os sistemas de saúde. O AVC do tipo isquêmico representa a maioria das ocorrências, o quadro clínico do paciente é correspondente ao tecido neural afetado, inicialmente a tomografia computadorizada sem contraste é o primeiro exame, por ser crucial para descartar a etiologia hemorrágica, a condução terapêutica se baseia em medidas neuroprotetoras através da estabilização da glicemia, temperatura e sódio, adequar os níveis pressóricos, mediante o prazo estipulado impor terapia antitrombótica. A manifestação hemorrágica, pode ocorrer por torção de aneurisma sacular originando o sangramento subaracnóideo ou por hipertensão gerando o sangramento intraparenquimatoso. A partir da análise das informações coletadas, elucida-se que o diagnóstico precoce e o período transcorrido até o manejo terapêutico são cruciais para o desfecho clínico do portador, ou seja, é possível a normalização ou ocorrer sequelas neurais e óbito

    Qualidade de vida de indivíduos com HIV: revisão integrativa / Quality of living of individuals with HIV integration review

    Get PDF
     A qualidade de  vida de pacientes vivendo com HIV/AIDS é essencial, tendo em vista o caso específico dos adolescentes é ainda mais importante porque o jovem além de lidar com a resistência e a aceitação da doença, deve também enfrentar os conflitos da puberdade.O presente trabalho tem como objetivo realizar uma revisão integrativa em relação a qualidade de vida dos pacientes com HIV. Trata-se de um estudo de revisão integrativa realizado no período de 2016 a 2017, utilizando-se o banco de dados Medline e Lilacs. Apesar do impacto da infecção pelo HIV/AIDS na saúde psicológica e nas relações sociais dos indivíduos infectados, assim como no domínio físico, o uso da TARV provocou consequências positivas na saúde psicológica, proporcionando a desconstrução da ideia de morte advinda ao diagnóstico de portador do HIV/AIDS e a construção de melhores perspectivas de vida. A adesão ao tratamento em HIV/AIDS está relacionada a um aumento da sobrevida e de sua qualidade. Porém deve-se respeitar a posição pessoal do portador para fazer ou não o tratamento

    Estimating the global conservation status of more than 15,000 Amazonian tree species

    Estimates of extinction risk for Amazonian plant and animal species are rare and not often incorporated into land-use policy and conservation planning. We overlay spatial distribution models with historical and projected deforestation to show that at least 36% and up to 57% of all Amazonian tree species are likely to qualify as globally threatened under International Union for Conservation of Nature (IUCN) Red List criteria. If confirmed, these results would increase the number of threatened plant species on Earth by 22%. We show that the trends observed in Amazonia apply to trees throughout the tropics, and we predict thatmost of the world’s >40,000 tropical tree species now qualify as globally threatened. A gap analysis suggests that existing Amazonian protected areas and indigenous territories will protect viable populations of most threatened species if these areas suffer no further degradation, highlighting the key roles that protected areas, indigenous peoples, and improved governance can play in preventing large-scale extinctions in the tropics in this century

    The Amazon Basin plays key roles in the carbon and water cycles, climate change, atmospheric chemistry, and biodiversity. It has already been changed significantly by human activities, and more pervasive change is expected to occur in the coming decades. It is therefore essential to establish long-term measurement sites that provide a baseline record of present-day climatic, biogeochemical, and atmospheric conditions and that will be operated over coming decades to monitor change in the Amazon region, as human perturbations increase in the future. The Amazon Tall Tower Observatory (ATTO) has been set up in a pristine rain forest region in the central Amazon Basin, about 150 km northeast of the city of Manaus. Two 80 m towers have been operated at the site since 2012, and a 325 m tower is nearing completion in mid-2015. An ecological survey including a biodiversity assessment has been conducted in the forest region surrounding the site. Measurements of micrometeorological and atmospheric chemical variables were initiated in 2012, and their range has continued to broaden over the last few years. The meteorological and micrometeorological measurements include temperature and wind profiles, precipitation, water and energy fluxes, turbulence components, soil temperature profiles and soil heat fluxes, radiation fluxes, and visibility. A tree has been instrumented to measure stem profiles of temperature, light intensity, and water content in cryptogamic covers. The trace gas measurements comprise continuous monitoring of carbon dioxide, carbon monoxide, methane, and ozone at five to eight different heights, complemented by a variety of additional species measured during intensive campaigns (e.g., VOC, NO, NO2, and OH reactivity). Aerosol optical, microphysical, and chemical measurements are being made above the canopy as well as in the canopy space. They include aerosol light scattering and absorption, fluorescence, number and volume size distributions, chemical composition, cloud condensation nuclei (CCN) concentrations, and hygroscopicity. In this paper, we discuss the scientific context of the ATTO observatory and present an overview of results from ecological, meteorological, and chemical pilot studies at the ATTO site. © Author(s) 2015
