摘要:
The present invention relates to proteic acid polymers (pLNs) comprising specific properties to reduce tissue damage and improve functional recovery after injury, and the production process of said proteic acid polymers. Those pLNs are preferably obtained using the protein laminin diluted in an acidic pH in the presence of divalent cation. The use of said proteic acid polymers for the production of a drug, a pharmaceutical composition containing such pLNs and a method of treatment of animals affected by traumatic, degenerative or inflammatory tissue injuries in nervous tissue, muscle, epithelial and connective tissues in general are also objects of the present invention.

The present invention relates to at least partially purified protein, capable of modulating the DNA replication in plants, muteins thereof, DNA coding therefor and to a method to confer to one ormore plant cells the capacity to provide such a protein or mutein. The invention also relates to plants, comprising the said DNA and the progeny thereof.
摘要:
Dengue virus (DENV) is a Flavivirus that causes the major human arbovirosis, for which no specific treatment exists. The C protein, the viral capsid protein, is a symmetric homodimeric a-helical protein that interacts with intracellular lipid droplets (LDs) during viral replication, possibly via a alpha2-alpha2' non-polar central patch that has been hypothesized to interact with lipids. The C protein binding sites to LD were identified, revealing a new function for a conserved segment in the N- terminal disordered region, and indicating that conformational selection is involved in recognition. The obtained results showed that C protein positively-charged N-terminal region prompts the interaction with negatively- charged LDs, after which a conformational rearrangement enables the access of the central hydrophobic patch to LD surface. Altogether, the results allowed the design of a peptide with inhibitory activity of C protein-LD binding, paving the way for new drug development approaches against dengue. The ability of this peptide to bind to LDs in a similar fashion to that of the C protein was demonstrated employing different techniques, such as, but not limited to, nuclear magnetic resonance, zeta potential analysis and atomic force microscopy. Moreover, the de novo designed peptides were tested regarding their ability to inhibit DENV C protein binding to LDs, having been shown that it effectively inhibits the DENV C interaction with LDs, a finding of direct applicability for dengue and related Flavivirus originated pathologies.
摘要:
The present invention patent application comprises a substrate for cultivating pluripotent stem cells that is produced by immobilising embryonic mouse fibroblast cells in ethanol, and the method for producing the substrate. The invention aims at providing a substrate having the necessary complexity to ensure that at least 95% of the cells remains pluripotent. Moreover, the use of feeding cell layers is replaced, culture conditions are maintained and contamination with animal molecules by the matrix is eliminated, with an inexpensive substrate that is compatible with national scientific demand.
摘要:
The proposed innovation relates to the biotechnological improvement of plant species of commercial interest. More specifically, the present invention relates to the production of transgenic plants with greater tolerance to water scarcity and salt stress by means of the expression of a new gene of coffee (of the Coffea arabica species), belonging to the HD-Zip family, and characterised by a homeodomain associated with a leucine zipper. The expression of this transcriptional factor is induced in leaves and roots of coffee plants subjected to various water scarcity conditions (both moderate and severe); transgenic plants that over-express this gene exhibit greater tolerance both to different drought intensities and to high salt concentrations.

摘要:
The present invention refers to the use of phthalimide and/or sulphonamide derivatives with nitric oxide donor properties, which have important activities in increasing the gamma-globin gene expression and anti-inflammatory and analgesic activities, effective in the treatment of hematologic diseases which require reducing the TNF-a levels and an exogenous source of nitric oxide. More particularly, the present invention describes the use of such phthalimide and/or sulphonamide derivatives for the treatment of sickle-cell diseases. The invention also has as a novel characteristic the disclosure of new functionalized phthalimide derivatives designed from the prototypes thalidomide and hydroxyurea, and designed rationally through the strategy of molecular hybridization for the treatment of said diseases. The invention still discloses a new method for obtaining a specific sulphonamide derivative which can be used in the preparation of a drug for the treatment of diseases which require reducing the levels of the TNF-a factor and an exogenous source of nitric oxide.
