Abstract: An in situ measuring instrument of the convergence angle (CA) of a dental preparation or stump in the field of dentistry, applied to humans or other species, having a movable bar, and a support bar arranged parallel to each other and coupled perpendicularly and slidable relative to a central bar by a first guiding hole at one end of the central bar and a second guiding hole at one end of the support bar which allow the relative vertical movement of the movable bar and horizontal movement of the support bar, allowing both bars to be adjusted to the base of the stump. This instrument allows measuring both natural and artificial teeth and implants, as well as fixed and mobile prostheses, just as if any device attached to the tooth (artificial or implant) is desired to be installed.

Abstract: This invention relates to a fungicidal composition for controlling phytopathogenic diseases, comprising a mixture of volatile compounds: 14-17% v/v ethanol, 28-33% v/v 3-methylbutanol, 18-21% v/v isobutyl acetate, 17-20% v/v isoamyl acetate, and 13-16% v/v alpha-bisabolol, relative to the total volume of the composition. The invention also relates to the use of the fungicidal composition in order to inhibit the growth of the pathogenic fungus Botrytis cinerea.

Abstract: A piece of scientific/technological equipment is presented for the generation of a convergent photon beam for radiotherapy or other applications. This equipment consists of adequately modifying the trajectory of an electron beam from a linear accelerator (LINAC) by applying magnetic and/or electric fields. These electrons perpendicularly impact the surface of a curved material that has a particular curvature ratio (anode), thus generating X-rays. The interaction of the electrons with the atoms of the anode's material generate X-rays with a non-isotropic angular-spatial distribution, with a greater concentration in the focal direction, which is defined by the geometry of the anode. A curved collimator with an adequate curvature ratio is attached to the back of the anode. The collimator is made up of an array of a great number of small holes that point toward the focal point. This device transmits X-rays solely in the focal direction.

Abstract: The present invention features compositions and methods for the treatment of erectile dysfunction. The compositions include substantially pure polypeptides derived from ?-latrotoxin and can include other substances, such as pharmaceutically acceptable carriers or diluents, liposomes, hydrogels, and additional active ingredients for the treatment of erectile dysfunction. Also provided are methods, including methods for using the compositions for treatment of erectile dysfunction and in the preparation of medicaments.

Abstract: The present invention discloses a method for cryopreservation of human spermatozoa: the method comprises providing spermatozoa free from seminal liquid; mixing the spermatozoa with vitrification medium, wherein the main cryoprotectant agent is 0.1-0.3 M sucrose; placing the sample inside straws and rapidly freezing them; refrigerating the straws with no need of liquid N2; and devitrifying the sample in a medium of the present invention. The present invention furthermore discloses a portable kit that makes easy to implement the method, said kit comprising vitrification and devitrification solutions in the volumes required to develop the method and the physical support to carry out the same, i.e. the straws. The use of this kit is also disclosed for the treatment of disorders related to reproductive failures.

Abstract: The present invention is directed to an active agent with contraceptive properties which corresponds to a peptide fragment of the Latrodectus mirabilisi's venom. The peptide generally includes the amino acid sequence of SEQ ID NO 2 or sequences that are at least 85% similar, obtained by chemical synthesis or through recombinant DNA technologies. Furthermore, a pharmaceutical contraceptive composition comprising the peptide fragment and one or more pharmaceutically acceptable vehicles is also described. The peptide fragment and pharmaceutical compositions are useful as a contraceptive and spermicide agent.

Abstract: The invention is referred to a new dentifrice composition with anticariogenic properties, which has as active anticariogenic ingredients a combination of propolis, methylparaben and propylparaben. From these 3 components, propolis is the major component, which is reinforced in its activity for a smaller amount of methylparaben and propylparaben obtaining a composition with a high anticariogenic composition without side effects. These active ingredients are present in the following percentages in relation to the total weight of the dentifrice composition: 2 a 10% of propolis; 0.01 a 0.30% of methylparaben 0.01 a 0.15% of propylparaben The dentifrice composition also includes a fluorinated compound and other auxiliary components usually used for formulation such as abrasives, moisturizing, foaming agents, thickeners, sweeteners, flavorants and demineralized water.
