Abstract: The invention refers to the design, synthesis and evaluation of 6 synthetic oligopeptides, that have not been previously described, designed from the T and B epitopes of allergens of group I of intradomiciliary mites of the species Dermatophagoides pteronyssinus, Dermatophagoides farinae and Blomia tropicalis, which can be used in the immunomodulation of individuals having immunocompetent systems and in the production of IgY polyclonal antibodies. The invention relates to a first method for obtaining a composition of IgY polyclonal antibodies that can be used as a diagnostic reagent having low cost and high reactivity in respect of intradomiciliary mites, and a second method for the detection of mite allergens, using the IgY antibody composition developed in the first method. The invention further relates to the composition of the IgY polyclonal antibodies.

Abstract: A device for controlling the pressure of a gas in a circuit via the generation of bubbles through a liquid, which is used to produce a continuous positive airway pressure (CPAP), is provided. The device includes a container containing a liquid and a bubble tube with one end located outside the liquid connected to a device connected to a patient's respiratory tract and the other end located within the liquid. The device also includes at least one hose for adjusting the level of liquid in the container.

Abstract: A device for sampling, diluting and analyzing particles and substances normally located on surfaces. The device includes a collection system which, through a rotating collecting surface and a scraper gathers the sample. The device also includes a tank-like storage system to store the diluting solution and a dilution chamber that permits the sample to mix with the solution and be diluted. This mixture is subsequently placed in contact with a detection system which is capable of discerning the presence or not of the substance being sampled.

Abstract: A method and apparatus for on-line measurement and forecasting of a species concentration while a reaction is taking place, based on the measurement of the electrical conductivity of the reacting volume, and using such measurement to evaluate a first mathematical function relating such value to the concentration of the species in the reacting volume. The evaluation of the first mathematical function requires as inputs: electrical conductivity trajectory, time elapsed, and other significant process variables; it generates as outputs the estimated actual species concentration and at least one forecasted concentration value.
