Although the response of macrophages to polyethylene debris has been widely studied, it has never been compared with the cellular response to ceramic debris. Our aim was to investigate the cytotoxicity of ceramic particles (Al2O3 and ZrO2) and to analyse their ability to stimulate the release of inflammatory mediators compared with that of high-density polyethylene particles (HDP). We analysed ...

The ability of space plasmas to self-regulate through mechanisms involving self-generated fluctuations is a topic high interest. This paper presents the results new advanced quasilinear (QL) approach for instability electromagnetic ion-cyclotron modes driven by relative alpha-proton drift observed in solar wind. For an extended parametric analysis, present QL includes also effects intrinsic ani...
