Abstract: The invention refers to the use of extracts of Deschampsia antarctica (EDA) for counteracting the human skin barrier damage caused by environmental aggressions and for preventing and/or ameliorating disorders related to an impaired barrier function.

Abstract: The present invention relates to a product obtained from gastropod spawn, to be used to prepare dermatological, cosmetic or cosmeceutical compositions designed for skin care; said product has the capacity to activate and mobilize skin stem cells, as well as prevent the loss thereof that takes place as a consequence of chronological and premature ageing. The present invention also relates to the process followed in order to obtain said product.

Abstract: The composition comprises of a component A selected from a hydroxylated derivative of benzoic acid or of cinamic acid, their esters, amides or salts, a glycoside of a hexose, and their mixtures; and a component B selected from quinic acid, shikimic acid, their alkaline metal or alkaline earth salts, their methyl esters, and mixtures of the same. This composition is suitable for protecting the skin against ultraviolet radiation coming from the sun or artificial sources, such as those used in phototherapy units and in sun tanning rooms. For application in the field of dermatology and nutrition, and, in particular, in the photoprotection of the skin and mucosa, photo-ageing and photocarcinogenesis, including protection of the immune system associated with the skin.

Abstract: This invention describes an agent for cutaneous photoprotection against UVA (I and II) and UVB radiation that contains an aqueous extract obtained from a plant in the Gramineae family from the Antarctic Continent (Deschampsia Antarctica), which presents both antioxidant and dissipation of excess UV radiation properties.

Abstract: Derivatives of the compound p-hydroxyphenyl propionic acid characterised by those derivatives having the general formulas (I) and (Ia), where n can take the values 1,2,3; R can be H or CH3 and R1 can be CH3 or H with pharmacological activity and their application in medicine for the treatment of disorders of the immunological system.

Abstract: The process to produce heterologous proteins in a minimal culture medium consists of (i) transforming a bacterial strain that is secretary in a minimal culture medium with a plasmid that contains the coding sequence of said heterologous protein, (ii) culturing said strain in a minimal culture medium, and (iii) recovering the heterologous protein. The bacterial strain that is secretary in a minimal culture medium can be obtained by means of a process that comprises (a) transforming bacteria adapted to grow in a minimal culture medium with a plasmid that comprises a DNA sequence that encodes for a protein that is toxic for a bacteria when it accumulates in the cytoplasm and whose synthesis is coupled to the secretion into the periplasm, (b) culturing said transformed bacteria in a minimal culture medium, and (c) selecting the surviving bacteria. It is applicable in the production of proteins of interest in bacteria that are secretary in a minimal culture medium.

Abstract: A process for obtaining polymers with antiviral activity is disclosed. Molecules carrying carbonyl groups and hydroxyl groups in the .alpha. position relative to the carbonyl, and molecules carrying amino and sulfonated groups, react in water or in mixtures of water with water-miscible solvents. The reaction takes place under specific conditions of temperature, time and pH. The first reacting molecule may be a monosaccharide whereas the second reacting molecule may comprise aliphatic aminosulfates. Upon completion of the reaction the polymeric material is purified by conventional processes such that the polymeric material has a molecular weight between 1,500 and 100,000. The polymeric material has antiviral activity, either lacks or has very low toxicity and anticoagulant activity, and is thus suitable for pharmaceutical preparations for use in topical or systemic antiviral therapy in humans or animals.
