摘要： In the membrane filtration of a liquid cell culture medium, superior flux rates and product recovery are obtained when a first charged particulate material and optionally a second charged particulate material bearing a charge opposite that of the first material are sequentially added to the medium prior to filtration.

摘要： A purified heparinase I, II and III free of lyase activity and each having a molecular weight of 42,800 84,100, 70,800, respectively, are produced by culturing Flavobacterium heparinum. The kinetic properties of the heparinases have been determined as well as the conditions to optimize their activity and stability.

摘要： A process for forming a purified solute from an aqueous solution is provided whereby a mixture of an extractant, a hydrate former and the aqueous solution is first formed. The hydrate former forms a hydrate with water while the solute does not form a hydrate. The extractant takes up the solute from the aqueous solution. The mixture is subjected to a temperature and pressure sufficient to form the solid hydrate of the hydrate former, an aqueous solution of the solute and a portion comprising the extractant containing the solute. The solute is recovered from the portion comprising the extractant and the solute.

摘要： A computer-implemented process determines candidate three-dimensional shapes of ring-shaped molecules through an exhaustive search of combinations of torsion angles of the bonds of the ring, given known bond lengths and bond angles for the bonds between atoms of the rings, a range of torsion angles and a resolution. Candidate combinations of the torsion angles are selected according to the range and resolution and coordinates of the atoms of the ring are determined for each candidate combination. It is then determined whether each candidate combination defines a physically possible ring. Indications of such candidate combinations are recorded. Candidate combination may then be selected from those recorded so that coordinates of atoms in candidate repetitive structures may be determined.

摘要： Heparinase is produced by growing the bacteria, Flavobacterium heparinum, in a defined medium consisting of a carbon source, two or more amino acids and mineral salts in the absence of protein. Heparinase is recovered by batch chromatography of the cell extract from hydroxylapatite by elution with sodium chloride and sodium phosphate buffer washes.

摘要： Pharmaceutical compositions for delivering an effective dose to a desired site of a heparinase. These compositions are based on the discovery that heparinase alone can inhibit angiogenesis. The effective dosage is dependent not only on the heparinase, but also on the method and means of delivery, which can be localized or systemic. For example, in some applications, as in the treatment of psoriasis or diabetic retinopathy, the inhibitor is delivered in a topical ophthalmic carrier. In other applications, as in the treatment of solid tumors, the inhibitor is delivered by means of a biodegradable, polymeric implant.
摘要翻译： 用于将有效剂量递送至肝素酶的所需位点的药物组合物。 这些组合物基于单独的肝素酶可以抑制血管发生的发现。 有效剂量不仅取决于肝素酶，而且还取决于递送的方法和手段，其可以是局部的或全身性的。 例如，在一些应用中，如在牛皮癣或糖尿病性视网膜病变的治疗中，抑制剂在局部眼科载体中递送。 在其他应用中，如在实体瘤的治疗中，抑制剂通过可生物降解的聚合物植入物递送。
