  • Patent number: 9751955
    Abstract: A method for regeneration of a cellulose containing material, comprises the steps: a) exposing the cellulose containing material to oxygen with an alkali aqueous solution at a pH of at least 9, and a temperature of at least 20° C., b) dispersing the cellulose containing material in the alkali aqueous solution, wherein the temperature of the alkali aqueous solution is lowered below 15° C., and wherein the pH of the alkali aqueous solution is above 9, c) adding an organic solvent to the dispersion to precipitate cellulose, and d) separating the precipitated cellulose by at least one method selected from filtering and centrifugation. The method makes it possible to maintain a high alkali pH value in the process, which saves costs since the pH value does not have to be lowered by additions of various additives. The method makes it possible to remove non-cellulose parts of the cloth.

  • Patent number: 9745334
    Abstract: The present invention is directed to new bifunctional compounds and methods for treating HIV infections. The bifunctional small molecules, generally referred to as CDM-Hs, function through orthogonal pathways, by inhibiting the gp120-CD4 interaction, and by introducing cytotoxic moieties to gp120-expressing cells, thereby causing cell death and preventing cell infection and spread of HIV. It is shown that CDM-Hs bind to gp120 and gp-120 expressing cells competitively with CD4, and these compounds cause cell death of HIV-infected cells, thereby decreasing viral infectivity. Compounds and methods are described herein.
