BdR-repr\ue9sentations dans le cas relatif

-representations in the relative case In this work, we develop a relative analogue of Sen's theory for -representations. We give applications to the theory of -adic representations, linking it to the theory of relative -modules and to the theory of -adic Higgs modules, developed by G. Faltings

Surconvergence des repr\ue9sentations p-adiques : le cas relatif

We generalize Tate-Sen's formalism; this allows to extend Sen's theory and to prove the overconvergence of $p$-adic representations in the relative case

Adhesion of Transferrin to Tisifilcon A Contact Lenses

Tear proteins accumulate on contact lenses causing lens deterioration and conjunctival irritation. We examined the adhesion of transferrin to contact lenses made of tisifilcon A, a rigid gas-permeable silicone hydrogel (FDA Group III). Lenses were incubated 2.0 mg/ml solutions of human holo-transferrin for 1, 2, 3, and 4 days, and protein adhesion was determined by bicinchoninic acid assay. Transferrin adhesion increased from day 0 to day 3 and then dropped after days 4 and 5. This pattern resembled transferrin adhesion to lenses made of polymacon (FDA Group I), alphafilcon (FDA Group II), omafilcon (FDA Group II) and balafilcon (FDA Group III) materials, but differed from the pattern of transferrin adhesion to etafilcon (FDA Group IV) material. Transferrin adhesion to tisifilcon A was greater than transferrin adhesion to all other materials except balafilcon, which had equivalent transferrin adhesion. These differences may be related to the positive charges on transferrin originating from arginine residues and the N-terminus. These cause transferrin to adhere better to the low water ionic Group III materials than to the non-ionic materials (FDA Groups I and II) and the high water ionic material (FDA Group IV)
