Abstract: Cosmetic composition which can be applied topically, comprising at least one compound of the general formula (I) in which R1 is H, C1-C20-alkyl, cycloalkyl or aryl-C1-C4-alkyl, n is 1-4, X is —O—, —NH— or —NR2— and R2H or C1-C20-alkyl; and at least one compound corresponding to the above formula (I) but in which XR1 with X having the possible meaning of —NH— is the residue of an alpha-amino acid; use of these compounds and of the composition for stimulating the synthesis of the proteins of the basement membrane; and also both those compounds of the formula (I) in which X is —NR2— and both R1 and R2 are different from H, and the compounds corresponding to formula (I) but in which XR1 with X having the possible meaning of —NH— is the residue of an alpha-amino acid, as such.

Abstract: Topical composition for use especially as a skin lightener, characterized in that it contains an effective amount of at least one compound of general formula (I) or a mixture of such compounds and/or an acid addition salt thereof: in which X is NH or a direct bond and n is 2, 3 or 4, preferably 2 or 3, and its use for lightening skin colour, for depigmenting liver spots and for evening out non-uniformities in skin colouration. The invention further relates to dermatologically effective compositions containing at least one disulfide of general formula (I) and at least one additional skin care ingredient.

Abstract: The drumstick provided for musical instruments such as drums and percussion instruments comprises a drumstick shaft and a drumstick head comprising an outlet opening from which the light of at least one light-emitting diode provided in the drumstick can exit. According to the invention, the drumstick comprises two shells that are complementary to one another and extend parallel to the longitudinal axis of the drumstick, said shells being glued together and preferably made of wood, at least the first shell of which comprising a notch within which a switching apparatus is disposed for controlling the light-emitting diode which is located in the drumstick head or which is located in the drumstick shaft and is connected to at least one fiber-optic cable that leads to the outlet opening of the drumstick head.
