Lack of nitrogen as a causing agent of Cylindrospermopsis raciborskii intermittent blooms in a small tropical reservoir.

Cylindrospermopsis raciborskii is the focus of many studies due to its toxicity and increasing blooms frequency. The comprehension of the factors that might trigger these blooms is fundamental for the maintenance of good freshwater quality. To better understand the autoecology of C.

[Health promotion in the basic units: analysis of the users' social representations about the role of the physical therapy].

The aim of this article is to identify the social representations of the users of operative groups about health and the physical therapy role in the health/disease process, as well as to verify how the representations of the users are related to the purposes of these groups. The present study was developed under a qualitative approach using the semi-structured interview. Users of the "Quality of Life" project from four basic health units of the city of Divinópolis, Minas Gerais State, were interviewed.

Thrombospondin-1 is a major activator of TGF-beta in fibrotic renal disease in the rat in vivo.

Background: Transforming growth factor-beta (TGF-beta), a profibrotic cytokine involved in many scarring processes, has to be activated extracellularly before it can bind to its receptors. Thrombospondin 1 (TSP1), a multifunctional matricellular glycoprotein, has been identified as an activator of TGF-beta in in vitro systems and during mouse postnatal development in vivo. TSP1 is expressed de novo in many inflammatory disease processes, including glomerular disease.
