The Brazilian biodiversity is recognized as one of the most expressive in the terrestrial biosphere and plays an important role to human well-being and health, providing basic products and ecosystem services. The products or goods from natural ecosystems include pharmaceutical material, food such as fishery, timber, and many others. Natural ecosystems also provide essential life-supporting services such as purification of air and water, climate regulation, reproductive and feeding habitats for extractivism, as well as maintenance of organisms responsible for cycling soil nutrients, making them available to plant absorption. Environmental disruption has impacted human well being and health, resulting in severe social poverty with spread of diseases. Increasing in vector-borne and diseases in humans and animals occur as a result of negative anthropogenic interventions in the natural ecosystems.

This paper aims to problematize the itinerancy as a way to operationalize care in the territory. With the creation of the Unified Health System, the notion of territory has become an organizing principle of work processes in primary health care and mental health policies. In the delicate field of coordination between these policies, itinerant practices now have a strategic importance in the deinstitutionalization of practices and construction of integral care. We take the deinstitutionalization and the integrality as conceptual operators that make the difference that Psychiatric and Health reforms want to print in the care practices. Warned that by joining in a posture of active search in the life territory of users, the itinerant practices fall in a field of tensions, which can both be called to work as a part of the State apparatus to population control, as in a strategic place for the construction of a contextualized care to users' way of life. We believe that it is possible to resist the social control mandate and build an ethics of care with itinerancy to explore the political power of the movement and transform the users' territory in a laboratory for the invention of life.

The association between paracoccidioidomycosis (PCM) and AIDS is relatively rare in contrast to the higher incidence of other systemic mycosis. The explanation may be that AIDS is still predominantly an urban disease, and the PCM is endemic in Latin American rural areas. The aim of this study was to detect the prevalence of Paracoccidioides brasiliensis infection in HIV-positive patients at an endemic area of paracoccidioidomycosis in Brazil. Skin test with purified 43 kD glycoprotein (gp43) was performed in 90 HIV/AIDS patients. The prevalence found was 12.2% and it may be even greater, considering that HIV/AIDS patients may not respond to the intradermal test, which depends on cellular immunity for its positivity.

Soil management systems, as those that integrate crop and livestock production, aiming at maintenance or recovering of soil quality, are indispensable for a sustainable agricultural management. Our hypothesis is that the land use for integrated crop-livestock systems improves soil physical properties, thus contributing to a sustainable agricultural soil use in the southwestern Cerrado region. The aim of this study was to investigate the influence of different tillage systems on some soil physical properties of the Cerrado. The soil under study was classified as an Oxisol and the following management systems were evaluated: a) soil under natural vegetation; b) soil under soybean for one year followed by three years of pasture; c) soil under soybean for four years, followed by four years of pasture; d) soil under continuous notillage soybean; e) soil under continuous pasture. Soil density, soil penetration resistance and aggregate stability in water were evaluated from 1995-2006. The soil use for continuous Brachiaria decumbens pasture degraded the soil physical properties less than crop-livestock integration and continuous crop systems.

The Pantanal biome is characterised by seasonal flooding which determines specific ecosystem processes, with the occurrence of adapted plants and animals to the annual shrinking and expansion of habitats due to the seasonal hydrological regime. Biodiversity abundance varies during the dry and wet seasons. The Pantanal's biodiversity is a fundamental component of ecosystem services for human society, including nutrient cycling, fish production, ecotourism, carbon storage, flood control, among others, which are relevant to regional and global environmental consequences. The biome has been impacted by the conversion of natural vegetation into agricultural fields and pasture for cattle raising, with alteration and loss of natural habitats and biodiversity. Major negative impacts occur in uplands, with drastic deforestation of savanna vegetation, where main rivers feeding the Pantanal have their springs. This article discusses future needs and priorities for ecological research, in order to better understand the biome's natural system, to achieve conservation and sustainable use.
