    Com o objetivo de avaliar o efeito do veranico ocorrido na estação Ășmida sobre o metabolismo de nitrogĂȘnio em cafeeiros em sistema a pleno sol e associados com abacateiro (Persea americana Mill.) e ingazeiro (Inga edulis Mart.), foi realizado este experimento. O estudo foi conduzido em propriedade situada no municĂ­pio de Barra do Choça, BA, composto por plantas de cafĂ© (Coffea arabica L.), variedade CatuaĂ­, sendo caracterizados dois campos experimentais (sistema sombreado x sistema a pleno sol). As avaliaçÔes foram realizadas em janeiro (perĂ­odo de veranico) e março (final da estação Ășmida), em cinco repetiçÔes por campo experimental. Os dados foram submetidos ao teste t por meio do programa SAEG, versĂŁo 9.1. Maior teor de NO3 - foi verificado no sistema a pleno sol, tanto no perĂ­odo de veranico como no final da estação Ășmida. Em março foi observado maior acĂșmulo de N-orgĂąnico no terço superior do cafeeiro a pleno sol e no terço mĂ©dio do cafeeiro sombreado. Maiores teores de nitrogĂȘnio total e a tendĂȘncia de maior atividade enzimĂĄtica da redutase do nitrato foram verificados nos sistemas arborizados, quando avaliados dentro do mesmo terço do cafeeiro nas duas estaçÔes

    Path of infectious diseases in Brazil in the last 50 years: an ongoing challenge

    ABSTRACT In this article, we comment on the main features of infectious diseases in Brazil in the last 50 years, highlighting how much of this path Revista de SaĂșde PĂșblica could portray. From 1967 to 2016, 1,335 articles focusing on infectious diseases were published in Revista de SaĂșde PĂșblica. Although the proportion of articles on the topic have decreased from about 50.0% to 15.0%, its notability remained and reflected the growing complexity of the research required for its control. It is noteworthy that studies design and analysis strategies progressively became more sophisticated, following the great development of epidemiology in Brazil in the recent decades. Thus, the journal has followed the success of public health interventions that permitted to control or eliminate numerous infectious diseases – which were responsible, in the past, for high rates of morbidity and mortality –, and also followed the reemergence of diseases already controlled and the emergence of until then unknown diseases, with a strong impact on the Brazilian population, establishing a little predictable and very challenging path

    Vascular Problems of the Pelvis

    Regardless of the gender, the human pelvis represents a complex anatomic region shared by the organs of the gastrointestinal and genitourinary tracts and the reproductive system. All these structures are included in a rigid bone case which also harbors the intricate neurovascular network that crosses over the pelvic area in direction to the lower limbs. The adequate approach of the diseases arising in the pelvic vascular network is difficult requiring precise anatomical knowledge and often the collaboration of interdisciplinary teamwork. The present chapter describes in detail the pelvic vascular anatomy and also provides a full discussion of both the tumor-related and tumor-unrelated diseases affecting these vascular structures
