Recombinant human factor VIII-specific affinity ligands selected from phage-displayed combinatorial libraries of protein A.

Factor VIII-specific affibodies were selected from phage displayed libraries constructed by combinatorial mutagenesis of an alpha helical bacterial receptor domain derived from staphylococcal protein A. Bead-immobilized recombinant human factor VIII (rVIII) (80 and 90 kDa chains) protein was used during competitive biopannings in the presence of free 80-kDa chain protein, resulting in the selection of several binders that showed dissociation constants (Kd) in the range 100-200 nM as determined by biosensor analyses. One variant (Z[rVIII:3], 90-kDa chain specific) was further characterized in small-scale affinity chromatography experiments, and showed efficient and selective recovery of biologically active rVIII from Chinese hamster ovary cell supernatant-derived feed stocks.

The manufacturing process for B-domain deleted recombinant factor VIII.

The development of a cell bank used in the routine manufacturing of a B-domain deleted recombinant coagulation factor VIII (BDDrFVIII) molecule involved stable insertion of the human BDDrFVIII gene into Chinese hamster ovary (CHO) cells, selection of a cell line capable of expressing consistent levels of active BDDrFVIII, and the establishment of a cell bank. The manufacturing process begins with the culturing of CHO cells in large bioreactors. Product synthesis is initiated by altering the cell culture conditions, thereby arresting the cells in a stationary growth phase and inducing elevated expression of BDDrFVIII.

Effects of four treatment methods on social phobic patients not suitable for insight-oriented psychotherapy.

Forty-two social phobic men and women, rated unsuitable for insight-oriented psychotherapy, received one of four randomly assigned types of treatment for 3 months. All patients received basal therapy (B) in the form of standardized information, self-exposure instructions, and anxiolytic medication. One group received this treatment only, with monthly appointments.

Effects of three non-insight-oriented treatment methods on agoraphobic women suitable for insight-oriented psychotherapy.

Twenty-three agoraphobic women rated suitable for insight-oriented psychotherapy received one of three randomly assigned non-insight-oriented types of treatment for 3 months and the effect was followed up after 9 months. All patients received basal therapy (B) in the form of standardized information, self-exposure instructions and anxiolytic medication. One group received this treatment only with monthly appointments.

Effects of four treatment methods on agoraphobic women not suitable for insight-oriented psychotherapy.

Seventy-three agoraphobic women rated unsuitable for insight-oriented psychotherapy, entered one of four randomly assigned types of treatment for 3 months. All patients received basal therapy in the form of standardized information, self-exposure instructions and anxiolytic medication. One group received this treatment only at monthly appointments (B).
