摘要： A modified annexin protein, preferably annexin V, is used to prevent thrombosis without increasing hemorrhage. Annexin binds to phosphatidylserine on the outer surface of cell membranes, thereby preventing binding of the prothrombinase complex necessary for thrombus formation. It does not, however, affect platelet aggregation necessary for hemostasis. The modified annexin molecule can be a homodimer of annexin, an annexin molecule coupled to one or more polyethylene glycol chains, or an annexin molecule coupled to another protein. By increasing the molecular weight of annexin, the modified annexin is made to remain in circulation for sufficient time to provide a sustained therapeutic effect.

摘要翻译： 修饰的膜联蛋白，优选膜联蛋白V，用于预防血栓形成而不增加出血。 膜联蛋白与细胞膜外表面上的磷脂酰丝氨酸结合，从而阻止血栓形成所必需的凝血酶原酶复合物的结合。 然而，它并不影响止血所需的血小板聚集。 修饰的膜联蛋白分子可以是膜联蛋白的同型二聚体，偶联到一个或多个聚乙二醇链的膜联蛋白分子，或与另一种蛋白偶联的膜联蛋白分子。 通过增加膜联蛋白的分子量，使修饰的膜联蛋白保持循环足够的时间以提供持续的治疗效果。

摘要： Disclosed is a method for modifying naturally occuring biocompatible biopolymers of plant and animal origin by subjecting same to ionizing radiation in the presence of a mediating gas, typically acetylene to enable one to selectively enhance and modify one or more of the physiochemical propserties of the starting materials which have a wide range of uses in medicine, food technology and other industrial applications. Notwithstanding the modifications, the biocompatibility of the biopolymer remains unchanged and no new or additional functional groups are introduced into the starting biopolymer.

摘要： The invention relates to a component for producing thermoplastically moldable, biodegradable and bright polymer mixtures based on starch, with good dimensional stability in water. The dimensional stability in water and the biodegradability of said component are adjustable and the component can be used for producing sheet materials, semi-finished or finished products, for example for packagings, containers, articles required in horticultural nurseries, and for other purposes. The invention, furthermore, relates to a process for producing the component from polyvinyl acetate and alkali silicate. A suspension of polyvinyl acetate is hydrolized and saponified in the batch process in the presence of catalytic additions such as, in particular glycerol, by adding the alkali silicate and hydroxides at high temperatures. Organosilicates of high homogeneity and fineness are formed. Additions of said component in small amounts have a positive effect on the phase compatibility of the hydrophilic starch and a hydrophobic polymer such as polyvinyl acetate in the course of preparation of the blend in the extruder. The properties of the extruded products are substantially enhanced.
