Abstract: The present invention relates to processes for recovering areas degraded by mining by means of soil treatment. In this context, the present invention provides a method for reusing ore concentrate waste, comprising the steps of (i) generating a solid or pasty residue from ore concentration, (ii) enriching the residue with at least two organic binders and a fertilizer to obtain an enriched/improved residue, (iii) depositing the enriched residue on the mined ground to form an enriched subsoil and (iv) depositing a topsoil layer on the enriched subsoil.

Abstract: Disclosed herein are compostions and methods for improving or enhancing pathogen resistance in legume plants. Compositions comprising polypeptides encoded by legume-derived nucleotide-binding site-leucine-rich repeat (NB-LRR) genes are useful in improving resistance in legumes to Asian soybean rust. Methods of using NB-LRR genes can be used to make a transgenic resistant legume plant.

Abstract: The present invention relates to the field of biotechnology and genetic engineering, and particularly to the expression of recombinant peptides. The inoculation thereof in cattle results in the production of an immune response capable of adversely affecting Rhipicephalus microplus ticks, which feed on the inoculated cattle, decreasing the number and reproductive capacity of this tick species. Such recombinant immunogen can be used as an effective vaccine for tick control. The technical goal is the design and construction of two synthetic genes made with preferred codons for Pichia pastoris and expression thereof from a recombinant peptide, which consists in a continuous sequence and of a recombinant peptide, respectively, and the drug composition based of said recombinant polypeptide.

Abstract: The present invention relates to the preparation of the recombinant antigen of the viral capsid of Porcine circovirus 2 (PCV-2) and modifications thereof, upon expression in a prokaryotic system, purification in the monomer form, recovery of virus-like particles (VLPs) and their use in vaccine formulations, diagnostic kits and a system for quantifying in vaccine lots of the PCV-2 antigen by means of a capture ELISA assay. The antigens and vaccine formulations can be used in animal's immunization in programs for combatting PCV-2-associated diseases in conventional swine breeding systems, and represent alternatives to the commercially available vaccines. The ELISA kit can be used for testing the quality of commercial and/or experimental vaccines against PCV-2.

Abstract: This invention is related to the field of immunology of protein biotechnology and particularly to the construction of synthetic immunogens which result, where inoculated, in the production by cattle of an immune response capable of lesion to the ticks feeding on the inoculated bovines, reducing their number, their weight and their reproductive capacity to such an extent that the constructed immunogen can be used as an effective vaccine for tick control on bovines. The technical object of the invention consists of the design and construction of two synthetic immunogens constituted of a continuous and defined sequence with forty-three (43) amino acids, found in different positions in the sequence of protein Bm86, their polymerization with cysteine in the N-terminal and in the C-terminal, the medicamentous composition based on said peptide(s) and the synthetic vaccine obtained thereby.
