Abstract: Methods for treating a bacterial infection by using a metallo-desferrioxamine complex.

Abstract: A method of-treating a relatively aged animal to reverse age-related changes in the lipid composition of organ and tissue cells, such as heart muscle cells, and the ability of the animal to withstand respiratory stress. A suspension of small unilamellar vesicles composed predominantly of egg phosphatidyl choline is administered parenterally to the animal, preferably over a period of several days and at a dose level of between about 0.1 and 1 grams lipid per kg body weight per day. Changes in the heart muscle cells are reflected in decreased levels of serum creatine phosphokinase. Liposome administration is continued until the serum creatine phosphokinase level drops at least about 50%. Also disclosed are liposome treatment methods for increasing longevity and male fertility.

Abstract: The present invention relates to a substantially purified heparanase obtained from the human SK-HEP-1 cell line and a method to purify the heparanase from a centrifuged dialyzed homogenate of the SK-HEP-1 cells or a cell culture medium containing the heparanase from the SK-HEP-1 cell line.

Abstract: A method for the ablative reshaping of material surfaces, including the steps of providing a source of an ablative beam having a given average fluence distribution over its cross-sectional extent, determining the ablation curve of the material to be reshaped, selecting, from said ablation curve, an ascending region having an at least approximately constant slope, selecting a beam fluence from among the fluences comprised in said region, irradiating the material surface to be shaped, and controlling the geometry of the material surface thus being reshaped by controlling the total amount of energy per unit area of said surface delivered during said irradiation.

Abstract: The invention provides a composition for protecting the heart from myocardial ischemia and reperfusion injury as well as for reducing post-ischemic damage, improving cardiac function and serving as a hypothermic cardiac preservative solution comprising N,N,N'N'-tetrakis-(2-pyridylmethyl)-ethylenediamine (TPEN) as active ingredient therein.

Abstract: A drug/liposome composition comprising an aqueous suspension of liposomes and, entrapped in the lipid bilayer region of the liposomes, an anthraquinone drug containing quinone and hydroquinone functionalities on adjacent anthracene rings. An iron-specific trihydroxamic chelating agent contained in the bulk aqueous phase of the suspension and a lipophilic free-radical scavenger contained in the bilayer region of the liposome cooperate to reduce chemical modification of both drug and lipid components of the composition. A preferred composition containing doxorubicin and alpha-tocopherol entrapped in the liposomes, and ferrioxamine in the aqueous suspension phase is effective in treating human neoplasms, with significantly reduced side effects over those produced by free-drug administration.
