The present invention relates to porous freeze-dried fibrin matrices substantially devoid of external anti-fibrinolytic agents, and methods of producing such matrices. Resilient matrices, also known as sponges, that are particularly beneficial for supporting three dimensional cell growth are obtained from plasma proteins substantially devoid of plasminogen or from partially purified plasma proteins, thus obviating the need for exogenous anti-fibrinolytic agents. Furthermore, incorporation of glycosaminoglycans and bioactive agents during the formation of the matrix results in a sponge having advantageous biological, mechanical and physical properties. The compositions of the present invention are useful clinically, per se or as cell-bearing implants.

The present invention relates to the cross-linked scuPA / suPAR complex and / or tcuPA / suPAR cross-linked complex, the process of preparation of the covalently bound single compound having fibrinolytic activity and use of the cross-linked scuPA / suPAR or tcuPA / suPAR complex in the prevention and / or treatment of thrombolytic disorders. The invention further relates to combination compositions and / or therapy regimens, comprising the cross-linked scuPA / suPAR complex or tcuPA / suPAR and one or more currently used plasminogen activators to achieve improved therapeutic efficacy and / or reduce side effects.

The present invention relates to an adrenomedullin derivative including an adrenomedullin peptide, or a fragment thereof chelated or otherwise bound to at least one active agent. Examples of active agents include a paramagnetic element, a radioactive element and a fibrinolytic agent, among others. Paramagnetic agents have a distribution that is relatively easily shown through Magnetic Resonance Imaging (MRI). Radioactive agents have applications in imaging and delivery of radiations, depending on the specific element included in the active agent. Delivery of fibrinolytic agents mainly to a specific organ, such as for example to the lungs, allows to substantially improve the specificity and efficacy of thrombolytic therapy by allowing local delivery of the fibrinolytic agent, thereby reducing the risks of major bleeding in the therapy of the organ. If the organ is the lungs, a non-limiting example of pathology treatable with the fibrinolytic agent is pulmonary embolus.

The present invention relates to a novel protease, a polynucleotide encoding the protease, and a fibrinolytic agent comprising the same. The protease is obtained from a new gene source by using metagenomic library technology, and can replace the conventional fibrinolytic agent.

The invention relates to an anti fibrinolytic composition comprising at least one tPA mutant that carries at least one point mutation substituting Ser481 to Ala on tPA, said mutant inhibits the fibrinolytic activity of at least one of tPA and uPA and therefore may be used for treating disorders associated with fibrinolytic processes, specifically, coagulopathies, thrombocytopenia and bleeding. The invention further provides methods and uses of the mutants of the invention.

The present invention is directed to methods of treatment of airway obstruction associated with fibrin-containing cast formation by administering a fibrinolytic agent.

The present invention is to provide a β-amyloid fibrinolytic agent containing a natural product as an active ingredient, and a therapeutic drug or preventive drug for diseases caused by β-amyloid fibrosis. It is a β-amyloid fibrinolytic agent, a therapeutic drug or a preventive drug for a disease caused by β-amyloid fibrosis, containing a dry powder, ground material and / or extract of earthworms as an active ingredient. The disease caused by fibrosis of beta amyloid is preferably Alzheimer's disease.

The presently disclosed subject-matter provides specific compositions, conjugates, device, kits and systems for depleting fibrinolytic agents from biological fluids. The presently disclosed subject-matter further relates to the resulting biological fluid products that are devoid in fibrinolytic activity, therapeutic methods and uses thereof. The conjugates comprise a particle, at least one linkerand at least one amino acid, derivative thereof or analog thereof being at least one of 4-(aminomethyl)-cyclo-hexane-carboxylic acid (tranexamic acid), epsilon-amino caproic acid, lysine, cyclohexanecarboxylic acid and 4-methyl-cyclohexanecarboxylic acid. A plurality of different conjugates (e.g. differing in partcile size or type of linker) can be used.

The invention discloses a preparation method and application of an amino acid chelated zinc modified Laem Tencel fiber, which is obtained through the esterification reaction of amino acid chelated zinc and Laem Tencel fiber, including ligand amino acid and zinc nitrate at a reaction temperature of 50 ℃ The chelation reaction was carried out under the conditions of ‑65℃ and pH value of 4‑7, the reaction product was precipitated by adding absolute ethanol, centrifuged and dried to obtain amino acid chelated zinc, which was dissolved in a fibrinolytic aqueous solution with cellulose pulp, Under the conditions of -130℃ and vacuum stirring, the esterification reaction was carried out for 3-4 hours to obtain the spinning solution, which was filtered and deaerated, and then wet-spun, solidified and formed in the spinning bath to obtain amino acid chelated zinc-modified ramie Tencel fiber. In the invention, the amino acid chelated zinc-modified lamina tencel fiber can improve the antioxidant property, has a good free radical scavenging effect, and can be used in the field of mask base cloth.

A method for the manufacture of biodegradable membranes for preventing adhesion formation followed open heart surgery is described herein. The manufacturing of biodegradable membranes is based on polymeric composition, comprised of copolymer of polyhydroxybutyrate / hydroxyvalerate (PHBV), poly (D, L-lactide) in the ratio of the dried powders of 3:1, the resulting mixture is dissolved in chloroform to a concentration of 6-9% followed by thorough mixing for 2 hours and heating up to 35° C. The membrane is produced by electrostatic spinning (electrospinning), wherein biologically active substances from fibrinolytic agents or direct anticoagulants are embedded in the structure of the fiber.
