  • Patent number: 11787909
    Abstract: Acrylamide-derived hydrogels and methods of fabrication thereof from an acrylic monomer, a crosslinking agent comprising an organosilicon compound, a polymerization initiator, a solvent and a polymerization accelerator, as well as their use in controlling circulation losses. The obtained hydrogels interact with the walls of the reservoir and exhibits an increase in viscosity, either at delayed times or in response to a given stimulus, such as changes in temperature, pressure, pH, salinity, using a simple and easily scalable methodology.

  • Patent number: 11535858
    Abstract: The present invention generally relates to the field of genetic engineering and obtaining transgenic traits for agronomic applications. More specifically, the present invention relates to a specific transgenic event in agricultural crops that improves plant characteristics. Yet more specifically, the invention relates to a polynucleotide construct comprising a gene from Arabidopsis thaliana. In particular, the polynucleotide construct of the invention comprises the gene AtBBX21 which encodes a B-box protein from Arabidopsis thaliana. The transgenic event of the invention increases green and seed yield, reduces photoinhibition, improves water use efficiency, increases tuber and chlorophyll production and improves photosynthetic rates, among others. The polynucleotide construct of the invention comprises a sequence depicted as SEQ ID NO: 1. The invention also provides a transgenic plant transformed with said polynucleotide construct, wherein said plant exhibits improved characteristics.

  • Patent number: 9744236
    Abstract: The present invention describes Photolabile Compounds methods for use of the compounds. The Photolabile Compounds have a photoreleasable ligand, which can be biologically active, and which is photoreleased from the compound upon exposure to light. In some embodiments, the Photolabile Compounds comprise a light antenna, such as a labeling molecule or an active derivative thereof. In one embodiment, the light is visible light, which is not detrimental to the viability of biological samples, such as cells and tissues, in which the released organic molecule is bioactive and can have a therapeutic effect. In another embodiment, the photoreleasable ligand can be a labeling molecule, such as a fluorescent molecule.
