Abstract:
Provided are water-soluble ligand-binding proteins derived from molluscs and analogs of ligand-gated ion channels, crystals thereof and their use for screening ligands of ligand-gated ion channels. In particular, water-soluble ligand-binding proteins are provided that are capable of forming multimers and are amenable to crystallization. The crystal structure of one of these proteins, an acetylcholine binding protein (AChBP) is provided, which can be used to generate 3D models of the extracellular ligand-binding domain of ligand-gated ion channels and thus for screening of drugs that act on these ion channels. Furthermore, chimeric proteins are provided that are capable of binding a ligand of a ligand-gated receptor, and comprising at least the amino acids of the AChBP determining solubility of the AChBP, in the same positions as in the AChBP, and furthermore comprising amino acids determining binding to said ligand.
Abstract:
The invention relates to peptides for use as antiviral agent, consisting of an amino acid chain which contains a domain of 10 to 25 amino acids, wherein the majority of the amino acids of the one half of the domain are positively charged amino acids and the majority of the amino acids of the other half of the domain are uncharged amino acids. The invention further relates to oligomers of these peptides consisting of at least two such peptides which are coupled to each other, optionally via a spacer, for use as antiviral agent, in addition to the use of the peptides and/or oligomers for the manufacture of a medicine for treating viral infections.

Abstract:
The invention relates to analogs of angiotensins, in particular to cyclised analogs having Ang(l-8) agonistic or antagonistic activity and to cyclised Ang(l-7) analogs with agonistic or antagonistic activity and displaying improved proteolytic resistance compared to their linear counterparts. Provided is a cyclic angiotensin peptide analog comprising a thioether-bridge linkage between the amino acids corresponding to positions Tyr 4 and Pro 7 in naturally occurring Angiotensin. Also provided is the use of analogs in therapy, for example hypertension.
Abstract:
The present invention relates to a pharmaceutical composition for photodynamic treatment of a fungal skin disorder, said pharmaceutical composition comprising a photosensitizer and an enhancer, wherein the photosensitizer is a cationic photosensitizer and the enhancer is chosen from the group of i) an acid, and ii) a metal chelating agent. Such a composition is capable of eliminating both conidiae and hy- phae. The invention also relates to a method for the preparation of the pharmaceutical composition.
Abstract:
A device for separating, analysing, detecting and/or determining particles in a liquid sample flow, particularly a microchip (1), wherein the device (1) comprises: -at least one sample flow separation area (4); -a sample flow supply (2) to supply the sample flow (S) to said sample flow separation area (4); and -at least one field generator (5, 6) which is configured to generate a field to substantially laterally separate certain sample flow particles when the sample flow flows through said separation area (4), for example via separation by free flow electrophoresis, free flow isoelectric focusing and/or isotachophoresis ; wherein the device is provided with an at least 2-dimensional detection pattern (9) located at least partly in and/or downstream with respect to said separation area (4), wherein said detection pattern (9) is suitable to interact with certain sample flow particles to be detected and/or determined. The invention also provides a method for separating, analysing, detecting and/or determining particles in a liquid sample flow.
Abstract:
Method for providing a thermal barrier coating and substrate . The thermal barrier coating (5) is provided on a thermally grown oxide (4) which is grown on a metallic bond coating (3) provided on said substrate (1) Adhesion between the bond coating (3) and thermally grown oxide coating (4) is improved by providing projections at the interface of yttriaalumina garnet (4) compounds. Service life at relatively high temperature of the thermally grown oxide coating (4) is improved by having alumina grain (6) with relatively large size. These are obtained by pre-annealing the bond coating (3) in an inert gas atmosphere followed by controlled preoxidation.
Abstract:
The present invention relates to constructs and methods for the screening, selection and identification of stress factors that disrupt the bioenergetics of the living cell, in particular the bioenergetics of the microbial cell. It provides in one aspect a promoter with an activity correalted to, and capable of serving as an indicator of change in the bioenergetics in the cell. It also provides fusion constructs and hosts comprising these constructs which may be used in the method of the invention. Thus, the invention allows for a rapid screening, selection and identification of stress factors for the cell, such as anti microbial compounds and antimicrobial treatments. These stress factors may be screened separately or in combination for their optimal effective concentration.
Abstract:
The present invention discloses a method for selecting a gene involved with nisin-resistance in a species of bacteria comprising providing candidate genes that are differentially expressed in nisin-resistant and sensitive strains of said species and selecting from said candidate genes at least one gene that results in an altered nisin-resistance phenotype in a strain of said species, when expression of said gene is altered. The invention further provides a bacterial strain obtained by the method of the invention, and a method for fermenting dairy products with said bacterial strain. The invention also discloses cheese produced by fermentation according to the invention.
