Abstract: The invention relates to haptens, immunogens and secondary immunoreactive agents, to the use thereof for producing wide-spectrum antibodies against quinolone-type antibiotics, to the application thereof to immunochemical analysis techniques, and to a kit enabling the detection of said antibiotics in biological samples from food products of animal origin.

Abstract: The invention relates to an aptamer, the structure thereof comprising at least one nucleotide sequence 5?-GGCA(A/G)GGA-3?, that can specifically bind to the poly(A) hairpin of the 5?UTR region of the genome of the human immunodeficiency virus type 1 (HIV-1), providing the method for producing aptamers with said sequence by means of a combination of experimental techniques of in vitro selection of nucleic acids with computational techniques of sequence optimization. The invention also relates to a DNA gene structure for synthesizing said aptamers, preferably RNA. The invention further relates to the different uses of the above-mentioned aptamer, including the use thereof as a biosensor molecule for detecting and/or quantifying HIV-1, as an inhibitor of the production of viral particles of HIV-1, and to the application thereof in medicine, the invention also relating to a method for treating a disease caused by HIV-1, and to a pharmaceutical composition comprising said aptamer.

Abstract: The invention discloses a system for the simultaneous detection and/or quantification of various analytes in a sample or for the simultaneous detection and/or quantification of an analyte in various samples, comprising: a multi-electrode chip (10) comprising an array of microelectrodes (11a, 11b, 11c, 11d); a single-duct cell (20), comprising a groove (21) which accommodates the multi-electrode chip (10) and a duct (22) through which a fluid sample can sequentially flow through each of the microelectrodes (11a, 11b, 11c, 11d) of a multi-electrode chip (10) when the latter is inserted into the groove (21); and a multi-duct cell (30), comprising a groove (31) housing the multi-electrode chip (10) and several independent ducts (32a, 32b, 32c, 32d) through which several samples can pass independently through each electrode (11a, 11b, 11c, 11d) of the multi-electrode chip (10).

Abstract: The canine excrement collector is a mechanical device for canine excrement collection. The canine excrement collector includes a telescopic mast with a handle and a walking leash on the upper end of the telescopic mast. The canine excrement collector further includes a trigger positioned at the upper end of the telescopic mast. The trigger is internally attached to a retractable pulley. The retractable pulley is connected to a cord whose free end extends longitudinally inside the telescopic mast, passing through a second pulley connected to a floating hexagonal piece, and reaching a fixed hexagonal piece located at a lower end of the telescopic mast.
