Abstract: A computer-based method for determining a sunscreen composition comprising a plurality of UV filter substances, comprises the steps of selecting at least one constraint for at least one characteristic of the composition to be determined (step 30), the at least one constraint comprising a sunscreen performance target; selecting an optimization objective from a plurality of optimization objectives (step 50); and automatically determining the sunscreen composition as a composition of filter substances from a set of filter substances (step 100), the composition meeting the at least one constraint and being optimized with respect to the selected optimization objective. The automatic determination comprises the steps of generating a plurality of candidate compositions, determining a sunscreen performance of the candidate compositions using a performance simulation tool and comparing the determined sunscreen performance of the candidate compositions with the sunscreen performance target.

Abstract: A method of treating a patient who has melanoma includes administering to said patient a composition containing a population of activated T cells that selectively recognize cells in the patient that aberrantly express a peptide. A pharmaceutical composition contains activated T cells that selectively recognize cells in a patient that aberrantly express a peptide, and a pharmaceutically acceptable carrier, in which the T cells bind to the peptide in a complex with an MHC class I molecule, and the composition is for treating the patient who has melanoma. A method of treating a patient who has melanoma includes administering to said patient a composition comprising a peptide in the form of a pharmaceutically acceptable salt, thereby inducing a T-cell response to the melanoma.
Abstract: An improved pasteurisation protocol for pasteurising microbial cells is disclosed. The protocol has three stages, a first heating stage, a second plateau stage at which the cells are held at a (maximum and) constant temperature, and a third cooling stage. Both the heating and the cooling stages are rapid, with the temperature of the cells passing through 40 to 80° C. in no more than 30 minutes in the heating stage. The heating rate is at least 0.5° C./minute and during cooling is at least ?0.5° C./minute. The plateau maximum temperature is from 70 to 85° C. By plotting the pasteurisation protocol on a time (t, minutes) versus temperature (T, ° C.) graph, one obtains a trapezium having an area less than 13,000° C. minute. Not only does this result in a smaller energy input (and so a reduction in costs), but a better quality (and less oxidised) oil results having a peroxide value (POV) of less than 1.5 and an anisidine value (AnV) of less than 1.0.

Abstract: The presence of either a calcium source or a carbonate source with GH30 xylanses significantly improves the release of xylan oligomers from maize and other feeds compared to the same xylanases without the calcium or carbonate source. Animal feed and animal feed additives comprising a combination of one or more polypeptides having xylanase activity; and one or more sources of calcium; and/or one or more sources of carbonate, wherein the polypeptide is a GH30 xylanase provide for improved xylan release from feedstuff.
