POLYMERIZATION LAMP AND COMPOSITES FOR FILLING DENTAL CAVITIES
The invention provides novel light-curable composites or composite compositions for filling dental cavities using a novel polymerization lamp (curing lamp). The novel composites or composite compositions have two polymerizable functions, since they contain a first initiator in a small amount and at least one further initiator in a greater amount. The first initiator reacts to different light wavelengths from the at least one further initiator. On irradiation with light for the first initiator the composite is converted to the gel state (preliminary curing), and on subsequent irradiation with the light for the at least one further initiator the composite cures completely (final curing). The invention likewise provides a novel polymerization lamp which emits the light wavelengths needed for the at least two initiators at the required times in the required intensity. The inventive use of the composites having two polymerizable functions or of the composite compositions having two polymerizable functions and of the novel polymerization lamp minimizes polymerization-related stresses in the tooth and filling.

The invention provides the use of at least one binary group 15 element compound of the general formula R1R2E-E'R3R4 (I) or R5E(E'R6R7)2 (II) as the educt in a vapor deposition process. In this case, R1, R2, R3 and R4 are independently selected from the group consisting of H, an alkyl radical (C1 - C10) and an aryl group, and E and E' are independently selected from the group consisting of N, P, As, Sb and Bi. This use excludes hydrazine and its derivatives. The binary group 15 element compounds according to the invention allow the realization of a reproducible production and/or deposition of multinary, homogeneous and ultrapure 13/15 semiconductors of a defined combination at relatively low process temperatures. This makes it possible to completely waive the use of an organically substituted nitrogen compound such as 1.1 dimethyl hydrazine as the nitrogen source, which drastically reduces nitrogen contaminations - compared to the 13/15 semiconductors and/or 13/15 semiconductor layers produced with the known production methods.

The present invention provides novel templates for peptide grafting. The template is a modified lasso peptide wherein an amino acid sequence of the wildtype lasso peptide comprising one to five amino acids is substituted by another amino acid sequence comprising one to five amino acids. In the modified lasso peptides according to the present invention, any site of the wildtype lasso peptide can be substituted by another amino acid sequence com- prising one to five amino acids. The term "another amino acid sequence" refers to any amino acid sequence that differs from the amino acid sequence of the respec- tive site in the wildtype lasso peptide. The modified lasso peptides according to the present invention are produced by applying the natural maturation machinery for the processing of lasso peptide pre- cursor variants. These variants are generated on the DNA level of the precursor genes by site-directed mutagenesis. The lasso peptide precursor proteins are het- erologously coexpressed with the two processing enzymes and the ex- port/immunity protein which transform the precursor into the modified lasso variant that is secreted into the culture supernatant from which the modified lasso peptide is extracted and purified.

Abstract
The present invention relates to a device for spreading active agricultural agents, wherein the device can be brought to the site of action temporally and spatially separated from the production process and comprises a dispenser as well as non-water-soluble nanofibers and/or mesofibers storing active agricultural agents. The polymers of which the nanofibers or mesofibers consist are preferably biodegradable. The active agricultural agents are selected from the group consisting of fungicides, herbicides, bactericides, plant growth regulators and plant nutrients. They are preferably pheromones, kairomones, and signal substances. The invention further discloses a method for producing said device, wherein the nanoparticles and/or mesofibers storing active agents are produced by means of electrospinning. The device can be used to bring active agricultural agents to the site of action thereof temporally and spatially separated from the production process. The spreading can be done mechanically or automatically. The site is preferably a useful area from pomiculture, viticulture, horticulture or a commercial row crop. The device according to the invention is particularly suited for controlling arthropods.
The invention relates to describing and applying gene sequences and the expressed proteins or protein sequences of the cytokine-dependent transcription factor STAT1 and the homologous sequences in other STAT transcription factors, and the protein sequences thereof, having an increased affinity, relative to the wild type of STAT transcription factors, for corresponding DNA sequences due to improved specific recognition of the corresponding DNA sequences. By identifying the underlying molecular mechanism for dissociating the STAT transcription factors from the corresponding DNA sequences, the invention enables improved verification of the activation state of each STAT transcription factor.

The present invention provides an apparatus and a method for distinguishing enantiomers with the aid of broadband femtosecond circular-dichroism laser-ionization mass spectrometry. In this case, an fs laser system is used, the laser pulse duration (τ) of which is less than or equal to 200 fs, with respect to a bandwidth-limited pulse, and the central wavelength (λ) of which is in the range between 200 nm and 1.100 nm. The spectral bandwidth of the laser pulse is chosen from bandwidths of less than or equal to 40 nm and those of more than 40 nm. The laser pulses are circular-polarized, in which case it is possible to change between right-hand and left-hand circular-polarized light. The circular-polarized fs laser pulses are used directly for ionization, wherein the light material interaction is enantiomium-specific. There is therefore no need for separation of substance mixtures. The wavelength which is appropriate for ionization of a specific analyte need never be known in advance: for bandwidths of less than or equal to 40 nm, the wavelength is varied in order to determine the appropriate wavelength. For bandwidths of more than 40 mm, the wavelength which is appropriate for the respective molecule is intrinsically contained in the spectrum. The sample to be examined and an achiral reference substance are examined simultaneously in the flight-time mass spectrometer for both circular polarizations. For a given ionization wavelength and polarization of the laser pulse, each flight-time mass spectrum obtained in this way was not only substance-specific but also enantiomium-specific. The apparatus according to the invention and the associated method combine CD spectroscopy and mass spectrometry and are suitable for identification and examination of enantiomers even in previously unknown substance mixtures.

Squamous cell carcinomas of the head and neck region (HNSCC) form a group of metastasizing tumours with a high mortality rate in humans and animals. Since it has been discovered that the biomolecule ozone inhibits the growth of various carcinoma cells in vitro, we have used the highly aggressive and lethal VX2 carcinoma of the New Zealand rabbit as HNSCC tumour model in order to test whether ozone has antitumour effects in vivo. Therapeutic insufflation of a medical ozone/oxygen (O3/O2) gas mixture into the peritoneum (O3/O2 pneumoperitoneum) at an advanced stage of a neoplastic disease led to a survival rate of 7/14 rabbits. Six of the seven surviving rabbits showed a complete tumour regression and the absence of local or remote pulmonary metastases. Insufflation of pure oxygen (O2) led to a survival rate of 3/13 animals, which was associated with complete tumour remission in two of the three surviving animals. Of the fourteen sham-treated animals, only one developed spontaneous tumour remission and survived. No side effects or changes in standard blood parameters were observed after repeated intraperitoneal insufflations with O3/O2 or O2 gas. Animals with O3/O2-induced tumour regression developed tolerance to reimplantation of the VX2 tumour. It was possible to reverse this by immunosuppression with a combination of dexamethasone and cyclosporin A, suggesting that the O3/O2-mediated activation of the body's immune surveillance has an antitumor effect. Although the exact mechanisms of action are still unclear, the available data indicates that O3/O2 pneumoperitoneum is a promising new strategy in tumour therapy.
