Abstract: The present invention refers to new purified compositions of long chain polyunsaturated fatty acids, or their salts or esters, characterized by being essentially free from other usually present—but structurally different—components, such as furan fatty acids, phytanic and pristanic acids, squalene, and some oligomers, as well as several “persistent” environmental pollutants, such as polychlorinated dibenzo-dioxins and polychlorinated dibenzo-furans, polychlorinated biphenyls, polybrominated diphenyl-ethers, polycyclic aromatic hydrocarbons, and others, which are also usually present and extremely toxic. The invention also refers to the purification method to obtain said compositions and the use thereof as food, food for special medical use, food and diet supplement, and drug.

Abstract: The use is described of a composition comprising either a) alpha-linolenic acid (ALA, C18:3 n-3) or b) docosahexaenoic acid (DHA, C22:6 n-3) or c) DHA in admixture with eicosapentaenoic acid (EPA, C20:5 n-3), in a ratio of 1:0.5 to 1:1.7, respectively, and/or the pharmaceutically acceptable derivatives and/or precursors thereof; either a) or b) or c) being in a concentration not lower than 70% by weight of the total fatty acids weight in the composition, for the preparation of a drug for the prevention and/or treatment of the disturbances of the central nervous system (CNS) such as epilepsy, schizophrenia, bipolar (manic-depressive illness) and unipolar (major depression) psychiatric disorders, and by degenerative Alzheimer's disease and related forms of dementia.

Abstract: Compositions for pharmaceutical use are described, comprising bisphosphonates and vitamin D in high concentration, destined to the intramuscular and subcutaneous intermittent administration for treatment of bone and skeletal system diseases, particularly osteoporosis, and sensitive cancers. These formulations are characterized by the use of a lipid and phospholipid emulsion at high concentration, having optimal carrier and solvent power for both the pharmacologically active components.

Abstract: A composition of long-chain polyunsaturated fatty acids containing at least 80% by weight of eicosapentaenoic acid (EPA, C20:5 n-3) and/or docosahexaenoic acid (DHA, C22:6 n-3) and at least 3% by weight of n-6 fatty acids, particularly C20:4 n-6 and C22:5 n-6, is reported. For a better chemical and biological characterization of the composition, the content of other C20, C21 and C22 n-3 acids different from EPA and DHA is preferably reduced to less than 3% by weight. In the composition all said acids are present in the form of free acids, or their salts, or C1-C3 alkyl esters. The described composition is useful for the production of a dietetic or pharmaceutical preparation useful for treatment of conditions sensitive to the action of EPA and DHA, particularly in subjects potentially exposed to bleeding problems or to problems caused by coagulation defects.

Abstract: The present invention relates to a process for the preparation of a composition comprising unsaturated compounds, in particular polyunsaturated compounds, which comprises concentrating and purifying the compounds by contact with silicon and/or aluminum derivatives. The process of the invention represents an advantageous substitute of the usual distillation processes, coupled or not to chromatographic processes, and allows to isolate and remove polar byproducts.

Abstract: A method is described for the production of wine, comprising the steps of: a) preparing a grape must; b) subjecting said grape must to clarification; and c) subjecting said clarified grape must to alcoholic fermentation to obtain said wine; characterized in that it comprises the step of adding to said clarified grape must, in sequence 1) at least one tannin and 2) a lysozyme. The use of tannin and lysozyme according to the invention enables to eliminate the sulfiting step involved in traditional methods and the sulfite-free wine thus obtained exhibits good chemical and microbiological stability.

Abstract: The use of some semisynthetic derivatives of the antifungal polyene partricin to selectively hinder the growth of tumor cells is here described. Their use can be associated with the use of other known antineoplastic agents, in particular in the cases where a resistance to these agents is present or has developed.The invention can be applied to systems of cell cultures as well as to the therapeutic practice.

Abstract: The use of ester and/or amide derivatives of partricin A and/or B to inhibit or forestall the growth of yeasts and molds in cell cultures of animal or vegetable origin, including hybridomas and cells whose DNA was modified. This use consists in adding the afore-said derivatives to the cell cultures in concentrations such as to inhibit the growth of yeast and molds but such as not to be toxic for the cell cultures themselves. The invention can be made use of, for instance, in the production of vaccines and in the conservation of organs and tissues intended for transplantation.
