PEPTIDE FOR USE IN THE REDUCTION OF SIDE EFFECTS IN THE FORM OF IMMUNOSTIMULATORY REACTIONS/EFFECTS

The aim of the invention is to effectively inhibit virus-, bacteria-, or parasite-infected cells and tumor cells in a targeted manner, even in the case of mutations. According to the invention, biologically active molecules are administered, said biologically active molecules including at least one protease inhibitor for at least one specific target protease of the virus-, bacteria-, or parasite-infected cells and/or tumor cells and at least one peptide-inhibited siRNA, PNA or RNA, the peptide bond of which is broken by the at least one target protease for the purpose of activating the peptide-inhibited siRNA, PNA or RNA. The molecules are used, for example, to influence the gene expression of diseased and infected organs or cells.

Biologically active molecules for influencing virus-, bacteria-, parasite-infected cells and/or tumor cells and method for the use thereof

A device for the measurement of chemical and/or biological samples, in particular by means of luminescence spectroscopy, comprises an irradiation unit, a sample receiver, at least one optical unit and a detector unit. The color marker in the sample, which contains at least one color marker, is stimulated by irradiation into producing luminescence and gives off light. The light emitted by the color markers is detected by detectors in the detector unit. According to the invention, the measurement results may be improved by the irradiation unit generating pulsed irradiation. The irradiation unit is thus preferably controlled by a control unit in such a way that the irradiation pulses impinge on the sample in a temporal sequence.

Method and device for the measurement of chemical and/or biological samples

The invention relates to a method for optically detecting at least one entity which is arranged on a substrate. The at least one entity is scanned with a measuring volume using at least one radiation source and a confocal optic. During a scanning process an auxiliary focus is generated by means of at least one second radiation source and a second optic. Radiation generated by the first radiation source is collimated by a first optic and radiation generated by the second radiation source is collimated by a second optic. A retroreflection from the auxiliary focus is detected by at least one detector and is used to measuring the position of an interface and, thus, for indirectly positioning the measuring volume. The position of the auxiliary focus relative to the measuring volume is adjustable in a defined manner.

Scanning microscopic method having high axial resolution

A micromechanical ejection pump for extracting small fluid volumes from a flowing sample fluid is provided with a substrate, and a canal for pressurized working fluid. The micromechanical ejection pump also has a canal for ejecting a fluid volume from the sample fluid. The working fluid canal runs into the extension of the sample fluid canal discharging crosswise thereto. The ejection canal connected to the sample fluid canal branches off from the working fluid canal opposite to the sample fluid canal. The working fluid canal and the ejection canal have in particular a substantially similar cross-section of 0.01-0.12 mm,, wherein the ratio of the cross-section of the sample fluid canal to the cross-section of the working fluid canal or the ejection canal is preferably between 0.2 and 0.5, more particularly between 0.3 and 0.4 and most preferably 0.35.
