Abstract: A locally-activatable bivalent thrombin binding agent is provided having two thrombin binding moieties for non-overlapping sites on a surface of thrombin linked together by a linker. The linker is a polypeptide having 5 to 30 amino acid residues existing in a folded state under an environmental condition where the binding agent is inactive. The linker changes conformation from the folded state to an unfolded state in response to a change in bulk temperature and/or to the presence of hyper-mobile water thereby activating the binding agent. Such locally-activatable thrombin binding agents can be administered systemically while only targeting specific sites of coagulation or inflammation since the thrombin binding agent will only activate at the site where the existence of atherosclerotic plaques has changed the local bulk temperature and/or created hyper-mobile water sufficiently to unfold the linker and activate the binding agent.

Abstract: ClotFoam is a sealant and hemostatic agent for use in cases of non-compressible hemorrhage for moderate to severe bleeding. It can be applied in the operating room through laparoscopic ports, or directly over lacerated tissue in laparotomy procedures or outside the operating room through a mixing needle and/or a spray injection method following intracavitary severe trauma or surgery. Its crosslinking technology generates an adhesive scaffold that carries a fibrin sealant required for hemostasis. Clotfoam produces a foam that spreads throughout a body cavity reaching the lacerated tissue to seal tissue and promote the coagulation cascade. The composition is biocompatible and non-inflammatory. The invention uses fibrin monomer polymerized by a change of pH as active sealing component. The viscoelastic properties of the foam as well as the rapid formation of a fibrin clot ensure that the sealant remains at the site of application without being washed away by blood.
Abstract: Silent brain ischemia (SBI) or ischemia of other organs can result from an embolism that is introduced into the arterial system during a medical procedure.

Abstract: Here, we present a photodegradable microparticle system that can be employed to entrap and deliver bioactive proteins to cells during culture. By using a photosensitive delivery system, experimenters can achieve a wide variety of spatiotemporally regulated release profiles with a single microparticle formulation, thereby enabling one to probe many questions as to how protein presentation can be manipulated to regulate cell function. Photodegradable microparticles were synthesized via inverse suspension polymerization with a mean diameter of 22 ?m, and degradation was demonstrated upon exposure to several irradiation conditions. The protein-loaded depots were incorporated into cell cultures and release of bioactive protein was quantified during the photodegradation process. This phototriggered release allowed for the delivery of TGF-?1 to stimulate PE25 cells and for the delivery of fluorescently labeled Annexin V to assay apoptotic 3T3 fibroblasts during culture.

Abstract: The present invention relates to recombinant blood coagulation factor IX (rFIX) mutants having factor VIII (FVIII) independent factor X (FX) activation potential. Five full length FIX proteins with combinations of mutations of amino acids important for functional activity of FIX and FIX wild type were cloned and expressed in HEK 293 cells. The proteins were tested by an activated partial thromboplastin time (aPTT) assay in FVIII-depleted plasma as well as in FVIII-inhibited patient plasma. In FVIII-depleted plasma functional activity of the FIX mutants was calculated as increased FVIII equivalent activity. The mutant proteins had increased FVIII equivalent activity. In FVIII-inhibited patient plasma the FEIBA equivalent activity was calculated for analysis of FVIII independent FX activation potential. The proteins had also increased FEIBA equivalent activity. Furthermore, the pre-activated FIX proteins had an increased activity in FIX-depleted plasma containing FVIII inhibitors.
