Abstract:
The invention relates to the use of gelatin-like proteins, or polypeptides, with an increased calculated glass transition temperature as stabilisers in lyophilized biological or pharmaceutical compositions.
Abstract:
The invention relates to compositions suitable for plasma substitution comprising as a plasma expander a recombinant gelatin-like protein. Characteristic is that the gelatin-like protein can be a monomer or a polymer like a dimer, trimer or a tetramer of a human recombinant gelatin-like protein having an isolectric point of less than 8. The resulting gelatin-like proteins provide a method to control the clearance rate of a plasma expander by its molecular weight. Preferably the gelatin-like proteins have a low hydroxyproline content which prevents the composition from gelling and thus allows the use of high-molecular weight proteins in order to establish a suitable colloid osmotic pressure. An additional advantage of the gelatin-like proteins is that these avoid the risk of anaphylactic shock that exists in conjunction with the use of commercially available preparations.
Abstract:
Method of generating an atmospheric pressure glow discharge plasma (APG), wherein said plasma is generated in a discharge space formed between at least one first electrode surface and at least one second electrode surface. The method comprises at least the steps of supplying a gaseous substance to said discharge space and powering said first and said second electrode surface for generating said plasma. Said step of supplying a gaseous substance to the discharge space comprises providing at least one intermediate gas supply stream from at least one of said first and second electrode surfaces. The step of supplying said gaseous substance to the discharge space further comprises providing a main gas supply stream for forcing the at least one intermediate gas supply stream in a direction along the first and second electrode surfaces.
Abstract:
The invention relates to compositions suitable for plasma substitution comprising as a plasma expander a recombinant gelatin-like protein. Characteristic is that the gelatin-like protein essentially is free of hydroxyproline. This absence of hydroxyproline prevents the composition from gelling and thus allows the use of high-molecular weight proteins in order to establish a suitable colloid osmotic pressure. Specific advantage of the gelatin-like proteins is that these avoid the risk of anaphylactic shock that exists in conjunction with the use of commercially available preparations.
Abstract:
The invention relates to methods for preparing vaccine and pharmaceutical compositions comprising recombinant or synthetic gelatin as a stabiliser and to the vaccine and pharmaceutical formulations themselves, as prepared by these methods.

This invention relates to a cosmetic composition for protection against UV radiation and its detrimental effects comprising a cosmetically and dermatologically acceptable carrier and a UV absorbing compound, not being flavonoid, which is covalently linked to a carrier molecule.
Abstract:
The present invention relates to a recording medium, in particular an ink-jet recording medium of photographic quality that has excellent ink absorption speed, good drying characteristics and a good image printing quality. According to the present invention, an ink-jet recording medium is provided, comprising a support and an ink-receiving layer which has an asymmetric membrane structure comprising a dense top layer adjacent to a microporous sublayer, said ink-receiving layer comprising at least one water-swellable polymer. The present invention is further directed to methods for obtaining such a medium.
Abstract:
The invention provides oil-in-water emulsions comprising recombinant collagen-like polymer in an amount sufficient to act as stabiliser of the emulsion. The polymer is especially a polypeptide which is free of helix structure, has an isoelectric point at least 0.5 pH units removed from the pH of the oil-in-water emulsion. Furthermore, amphiphilic recombinant collagen-like polymers are provided for use in oil-in-water emulsions. The amphiphilic polymers are polar at one end as a result of a relative abundance of polar amino acids, and apolar at the other end as a result of a relative abundance of apolar amino acids.
Abstract:
The present invention is directed to a method and arrangement for controlling a glow discharge plasma in a gas or gas mixture under atmospheric conditions, in a plasma discharge space comprising at least two spaced electrodes (2), wherein at least one plasma pulse having an absolute pulse maximum is generated by applying an AC plasma energizing voltage to the electrodes (2) causing a plasma current and a displacement current. The plasma is controlled by providing a relative decrease of the displacement current after the pulse maximum. In a preferred embodiment, the energizing voltage is applied through a series circuit of a choke coil (3) and a non-saturable inductor (4).
Abstract:
The present invention provides an arrangement and method for generating a uniform and stable plasma. The arrangement comprises a discharge space (7) between at least a pair of electrodes (1, 2), which electrodes (1, 2) are arranged for providing an electric field and for generating a plasma in the electric field. At least one of the electrodes (1) has a boundary surface (6) with the discharge space (7). The boundary surface is comprised of one or more alternately arranged conductive (4) and insulating regions (5). The invention further relates to an electrode (1) for use in the arrangement described. The invention may, for example, be used in dielectric barrier discharge configurations, or in arrangements for generating plasmas at atmospheric pressures, or for generating plasmas at low temperatures, such as generating atmospheric pressure glow plasmas (APG) for material processing or surface (3) treatment purposes.
