Abstract: In a method for efficiently analyzing a posttranslational modification of a protein using no enzyme, a protein or peptide to be analyzed is reacted with an acid (a thioester or hydrazine) under certain conditions. This makes it possible to detect variously modified states of a protein or peptide, whereby the identification of each specific modifying group and the position of each modified amino acid can be efficiently analyzed using a chemical method and a mass spectrometric apparatus.

Abstract: The present invention relates to identification tagging, and is specifically directed to identification tagging of ammunition. An isotopic taggant is deposited in a layer at the interface between the primer and the propellant so that, as the ammunition is fired, the taggant is dispersed throughout the propellant. The taggant is thus contained in the gunshot residue formed during the firing, and can be read by analysis of residue particles. Alternatively, the taggant may be deposited in a layer under the primer reactants, or in pellets which are easily destroyed by the chemical reactions involved in firing the ammunition, again dispersing the taggant throughout the propellant and the gunshot residue. Non-isotopic chemical taggants may also be employed if they are encoded so as to minimize the possibility of the information being destroyed or improperly read after the taggants are exposed to the chemical reactions in firing the ammunition.
Abstract: The invention relates to novel aromatic compositions consisting of HLA molecules, which two different potential perfume carriers are assigned. The invention aims at developing novel aromatic compositions consisting of HLA molecules based on the selection of alleles of genes which are relevant from an olfactory viewpoint and subsequent processing thereof. According to the invention, the aromatic compositions are produced by selecting one allele amongst known class I HLA alleles, which differs in at least one characteristic from other alleles of HLA class I molecules and which is present in less than 5% of individuals of the world population; the protein that is coded for by the selected allele undergoes assembly in the presence of ?2-microglobulin (?2m); the formed HLA class I molecules are purified with the bonded peptides and fragmented with the protease, and the odor-active substances resulting from fragmentation are added as individual components or as a mixture to a cosmetic preparation.

Abstract: A cuvette package for loading multicell cuvettes from the package into measurement instruments having their cuvette loading accessories designed to accept known packages. On top of a row of multicell cuvettes is attached a detachable bonding strip having a width smaller than that of the width of the row of multicell cuvettes. The bonding strip serving to keep the row of cuvettes together during transport and being easily detachable when the cuvettes are being loaded into the instrument. The multicell cuvettes are loaded into the instrument from the dispensing device which supports the cuvette in place and has its top surface provided with an opening permitting the removal of the strip by pulling off from the supported multicell cuvette package.
Abstract: The invention provides an apparatus, methods, and compositions for dispensing a fragrance onto laundry in a dryer without substantial loss of that fragrance during the drying process. The apparatus includes an electrostatic vapor generator capable of dispensing a fragrance composition into a dryer. The invention also provides electrostatically dispensable fragrance compositions containing glycols, vegetable oils, and perfumes. The invention further provides a kit and method for enhancing residual fragrance on laundry by adding a fabric conditioning composition and a fragrance composition in separate steps during the laundering process. The invention includes embodiments wherein the dispensation of the fragrance compositions is computer controlled.

Abstract: The invention relates to indicator molecules for detecting the presence or concentration of an analyte in a medium, such as a liquid, and to methods for achieving such detection. More particularly, the invention relates to copolymer macromolecules containing relatively hydrophobic indicator component monomers, and hydrophilic monomers, such that the macromolecule is capable of use in an aqueous environment.
Abstract: The invention relates to compounds of the general formula (1), wherein R represents a group CH?N—OH or a group CN. The inventive compounds are characterized by interesting and original odor characteristics which diffuse extremely well and are suitable for use as fragrances, for example in cosmetic preparations, technical products or in alcoholic perfumery.
Abstract: Diagnostic method, based on the amounts of biogenic amines that are contained in a body fluid or other sample. A number of measured parameters related to the desired diagnostic information are derived from the amounts. For each diagnostic information desired, an input consisting of the identification of the diagnostic information is provided. The input is compared to the measured parameters and a diagnostic response is derived from the comparison. The measured parameters may be derived from the amounts of the biogenic amines according to a program stored in a memory.
Abstract: The present invention provides methods, compounds, and kits useful in the analysis of reaction products and components of reaction mixtures, and in certain embodiments for the rapid and simultaneous determination of enantiomeric ratios, percent conversions, and absolute configurations.

Abstract: The invention concerns a composition capable of indicating by color change when consumer articles, particularly volatile material dispensers, containing or associated with the composition have become inefficient in use. The composition includes: a) a volatile liquid component, b) a non-volatile component of an oxide or hydroxide of the metals of group III or IV of the periodic table and a polymer obtainable by the reaction, in the presence of the volatile liquid component, of a functionalized polymer with a cross-linking, and c) a dye capable of changing color as a function of the medium in which it is incorporated. Optionally, the composition can also contain an effective amount of an acidic compound. The invention also concerns the consumer article containing the composition, in particular a device aimed to diffuse a volatile or partially volatile liquid, more specifically an air freshener.
