The invention relates to a timer device capable of performing one or more control actions in response to the time lapsed since a user initiated action took place. The timer device comprises contact means operatable between two conditions, timer means, and means for storing first and second time stamps. The device further comprises control means for setting a first time stamp in response to the contact means being operated between first and second conditions, setting a second time stamp in response to the contact means being operated between the second and first conditions, calculating the time elapsed between the two time stamps, comparing the elapsed time with a preset time value, and performing a control action if the elapsed time is greater than the preset time value.

In a process for producing an iron-dextran compound for use in parenteral treatment of iron-deficiency in humans or animals a stable compound of desired relatively low molecular weight is obtained by using first hydrogenation and then oxidation to convert reducing terminal groups on the dextran molecules before reaction with the iron. By varying the ratio of hydrogenated groups to oxygenated groups the average molecular weight of the resulting iron-dextran compound can be varied.

The present invention relates to a method for improving the properties of a cellulolytic enzyme by amino acid substitution, deletion or insertion, the method comprising the steps of:a. constructing a multiple alignment of at least two amino acid sequences known to have three-dimensional structures similar to endoglucanase V (EGV) from Humicola insolens known from Protein Data Bank entry 4ENG; b. constructing a homology-built three-dimensional structure of the cellulolytic enzyme based on the structure of the EGV; c. identifying amino acid residue positions present in a distance from the substrate binding cleft of not more than 5 Å; d. identifying surface-exposed amino acid residues of the enzyme; e. identifying all charged or potentially charged amino acid residue positions of the enzyme; f. choosing one or more positions wherein the amino acid residue is to be substituted, deleted or where an insertion is to be provided; and g. carrying out the substitution, deletion or insertion by using conventional protein engineering techniques. Also described are cellulase variants obtained by this method.

Glycosides of diacylglycerol, e.g. 3-β-D-galactopyranosyloxy-2-(octadeca-9Z,12Z,15Z-trienoyloxy)propanyl octadeca-9Z,12Z,15Z-trienoate (GOPO), which was isolated from extracts of rose-hips by activity guided fractionation, can be used as an oral anti-inflammatory agent for the treatment of inflammatory diseases such as arthritis and osteoarthrosis.

Disclosed is an apparatus for scanning a surface with electromagnetic radiation. The apparatus comprises a base plate for supporting a medium said medium having a scanning surface to be scanned, an optical head unit adapted to scan the scanning surface with electromagnetic radiation propagating along an optical axis, a fluid film generation unit connected to the optical head unit and adapted to generate a fluid film between the scanning surface and a gliding surface of the fluid film generation unit for maintaining a predetermined distance between the gliding surface and the scanning surface during scanning operation of the optical head unit across the scanning surface, and control means for controlling the position of the fluid film relative to the optical axis.
摘要:
This invention relates to a doser comprising a syringe (2) with a needle (3) which extends beyond the doser (1), which comprises an engagement face (4) in the vicinity of the needle so that the engagement face rests against the surface of the tissue into which the needle is inserted. Detector means (5) are provided on said engagement face to sample signals on the skin of the patient. The invention further provides means (13) for receiving external information related to health monitoring of a patient. This provides a doser that may record heart rate, EKG, BGM and hypo-alarm administered medicine. The doser may further be arranged to calculate an appropriate dose of medication on the basis of a number of acquired inputs.
