“…Nevertheless, a final expression for the magnetic filtration theory has not been developed yet. There are still contradictions between the experimental results reported in the literature (Franz and Franzeb, 1998;Svoboda, 1994Svoboda, , 2001Ebner and Ritter, 2001;Clarkson and Kelland, 1978), and these results cannot be used for special industrial applications since they were obtained in laboratory conditions and not scaled up; however, these results have been derived specifically for magnetic separators used in the mineral industry. It must be noted that porosity of the magnetic filter matrices and size of particles captured in the filter are less than those in the magnetic separators.…”

The magnetic filtration theory was evaluated to intensify the filtration of industrial fluids by magnetic filters. Effects of filtration velocity and external magnetic field intensity on filter performance were investigated and the dependence of the logarithmic efficiency coefficient on filtration velocity was questioned. It was concluded that change in the magnetic susceptibility of the dispersion particles, caused by external magnetic field, and change in the flow rate properties of the liquid alongside the filter pores are the most essential factors to be considered in the design, development, and modeling of magnetic filtration systems in various industrial areas.

“…High-gradient magnetic separation of micron-size particles has been modeled extensively by considering the important forces on the magnetic particles as they flow through the separator (Ebner and Ritter, 2001;Gerber and Birss, 1983;Ying et al, 2000). Particle capture has been shown to be governed by competition between the magnetic attraction of the particles to the magnetized wires and the viscous drag on the particles from the flowing fluid.…”

The role of intracellular proteases (e.g., calpains and caspases) in the pathophysiology of neuronal cell death has been extensively investigated. More recently, accumulating data have suggested that extracellular proteolysis also plays a critical role. The two major systems that modify the extracellular matrix in brain are the plasminogen activator (PA) and matrix metalloproteinase (MMP) axes. This Mini-Review delineates major pathways of PA and MMP action after stroke, brain trauma, and chronic inflammation. Deleterious effects include the disruption of blood-brain barrier integrity, amplification of inflammatory infiltrates, demyelination, and possibly interruption of cell-cell and cell-matrix interactions that may trigger cell death. In contrast, PA-MMP actions may contribute to extracellular proteolysis that mediates parenchymal and angiogenic recovery after brain injury. As the mechanisms of deleterious vs. potentially beneficial PA and MMP actions become better defined, it is hoped that new therapeutic targets will emerge for ameliorating the sequelae of brain injury and inflammation.
