Abstract:
An insecticidal polymer matrix containing Piperonyl Butoxide (PBO) and deltamethrin (DM), wherein the ratio between the content of PBO and the content of DM in terms of weight is higher than 3.
Abstract:
The diagnosis apparatus according to the invention for the picture providing recording of fluorescing biological tissue by way of an endoscope contains a stimulation light source which beams spectral components suitable for fluorescence stimulation into the tissue through the endoscope. The fluorescent light reflected by the tissue reaches through the endoscope optics into a head piece where it is split into a green, and spacially separated from this, a red spectral component and falls each on one half of a CCD solid body of a highly sensitive black and white camera. In an electronic and processor component the video signals allocated to the green and to the red spectral component are processed into two separate processing channels in a manner such that the separately processed green-red video signals are simultaneously inputted to a color video monitor and here may be superimposed to a red-green monitor picture, which may show changes of tissue indicating disease, for example dysplasia, carcinomas in situ etc., in all organs which are endoscopically accessible.
Abstract:
By incorporating PBO and phtalocyanine in a polymeric matrix, the surface concentration of the PBO after migration to the surface is reduced relatively to a matrix without phtalocyanine. This can be used to control the migration of PBO and retain PBO for a long-lasting effect.

Abstract:
An insecticidal polymer matrix containing HDPE (high density polyethylene), LDPE (low density polyethylene), preferably containing PBO (Piperonyl Butoxide) and DM (Deltamethrin), wherein the ratio of the contents of HDPE to LDPE is between 5 and 20 and most preferably between 8 and 10. The matrix is highly useful for bed nets against mosquitoes.
Abstract:
The invention concerns a 5-aminolevulinic acid ester (E-ALA) solution for producing a pharmaceutical preparation useful for diagnosing and/or treating tissue and/or cell pathologies by local radiation exposure using radiation emitted by a light source energy followed, in the case diagnosis, by detection of fluorescent protoporphyrin IX (Pp1X). The E-ALA concentration in the solution is less than 1% and ranges between 0.01% and 0.5%. The low E-ALA concentration in the solution increases Pp1X synthesis and homogenises its distribution in the cell layers while highly reducing the secondary toxicity for the treated cells.
