13. Characterization and use of the Zerede Stream watershed, Timóteo-MG / Caracterização e uso da bacia hidrográfica do Córrego Zerede, Timóteo-MG
It is common the no integrated treatment of the studies of the natural phenomena, perhaps presupposing of that knowing some parts of a system it can be known in this whole. However, to conserve the nature, particularly the soil and the water, it is necessary the coordinated and integrated envolvement of everyone, making that the small watershed corresponds t

14. Water dynamics in level terraces. / Dinâmica da água em terraços de infiltração.
Terracing is a soil conservation practice that aims to reduce water and soil loss by interception of runoff that occurs when rainfall intensities exceed infiltration capacity. Actually, dimensions of terraces are being determined in an empirical way; however, a more detailed understanding of the physics behind the hydrological functions of terraces would all

15. Erosion number and area progression in the wrists and hands of rheumatoid patients: a quantitative microfocal radiographic study.
Microfocal radiography has been used to evaluate the relation between erosion number and erosion area in the hands and wrists of 51 patients with early to moderately advanced rheumatoid arthritis. The hands of these patients showed different patterns of erosion progression, in terms of the relation between changes in number and area, and included those showi

16. Quantitative microfocal radiography accurately detects joint changes in rheumatoid arthritis.
Microfocal radiography, producing x5 magnified images of the wrist and hands with a high spacial resolution (25 microns) in the film, permitted direct measurement of erosion area and joint space width in patients with rheumatoid arthritis. The magnitude of errors relating to direct measurement, repositioning the wrist and hand on successive x ray visits, rep

17. Biomechanical and biochemical properties of dog cartilage in experimentally induced osteoarthritis.
The finding of other investigators that increased water content is often associated with signs of a torn collagen network in human osteoarthritic (OA) cartilage led to this study. In the Pond-Nuki model of post-traumatic OA experimental but not control femoral condylar cartilage showed evidence of breakdown and stiffening of collagen network as assessed by m

18. In vivo model of cartilage degradation--effects of a matrix metalloproteinase inhibitor.
OBJECTIVES--To develop a model of cartilage degradation that (i) enables the testing of synthetic, small molecular weight matrix metalloproteinase (MMP) inhibitors as agents to prevent cartilage erosion, (ii) permits the direct assay of the principal constituents of the extracellular matrix (collagen and proteoglycan) in both the non-calcified articular cart
