  • Publication number: 20200138919
    Abstract: An easily administrable drug treatment to increase the recanalization rate associated with intravenously t-PA would represent a major advance in the acute ischemic stroke (AIS) management. The inventors demonstrate the presence of NETs network in intracranial thrombus extracted during AIS reperfusion procedures. Thrombi are encapsulated by these NETs network, which confer t-PA resistance. In fact, in presence of DNAse 1, t-PA-induced thrombolysisis accelerated, whereas DNAse alone is inefficient. These results suggest that a co-therapy associating t-PA and DNAse 1 may potentialize t-PA efficacy. Accordingly, the present invention relates to a method of treating an acute ischemic stroke (AIS) in a patient in need thereof comprising administering to the patient a therapeutically effective combination of t-PA and DNAse, wherein administration of the combination results in enhanced therapeutic efficacy relative to the administration of t-PA alone.

  • Patent number: 9654751
    Abstract: A method, apparatus and system for providing color grading or color correction for displays includes a plurality of virtual device models where each virtual device model has a virtual model specification (VMS) which controls a display feature. Each display includes a display specification including a display requirement or requirements. An apparatus of the present invention is configured to compare the display feature of at least one VMS against the display requirement of the display specification to determine a best match therebetween to select a virtual device model to control a display picture. Color correction is further provided in post production using the VMS to provide consistency across multiple display types.

  • Patent number: 8847976
    Abstract: A method, apparatus and system for transforming a calorimetric adjustment of a sequence of images from an input color space into an output color space includes a color adjustment device for determining a transformation table for converting the input color space of the sequence of images to an output color space, for applying a first order approximation to at least one subset of the sequence of images, the subsets of the sequence of images defined by the transformation table, and if the sequence of images has not reached convergence, for applying a second order approximation to at least one subset of the sequence of images. In one embodiment, the color components of the output color space are defined by a combination of intermediate terms, where the number of the intermediate terms corresponds to the number of input color space components. The transform is configured to survive a video distribution workflow.

  • Patent number: 7491299
    Abstract: In the photochemical synthetic process in semi-continuous mode according to the invention, a reactor comprising two zones is used, the radiating portion of the lamp(s) being totally immersed in a first zone which is completely filled with reaction medium and spills off via an overflow into a second zone whose volume is sufficient to contain the volume of reaction medium originating from the first zone and corresponding substantially to the volume of the reagent(s) gradually introduced.

  • Publication number: 20080102135
    Abstract: A method for making, storing and using a surgical graft from equine amniotic membrane in veterinary ophthalmology. The amniotic membrane is obtained from equine placenta, from which the chorion has been separated. Sheets of the amniotic membrane are cut to size and mounted on filter paper. The cells of the amniotic membrane are killed, preferably while being frozen and thawed in the storage solution. The equine amniotic membrane can be used in a variety of ocular surgeries in horses but also other species such as food animals, dogs and cats. It represents a strong biomaterial that will give a good physical support to the ocular tissues while inducing a minimal amount of scarring which is primordial in ocular surgeries in order to obtain the best visual outcome.

  • Publication number: 20060068645
    Abstract: A modular electric terminal connector, in particular for a monobody defibrillation probe. This terminal includes a stacking of elementary cylindrical parts, alternatively conducting and insulating, each of which includes a central cavity receiving the sheath of a cable comprising several connection wires. An axial pin, placed on a casing at the free extremity of stacking, is connected to a respective connection wire to form an axial contact of the terminal. Rods passing through homologous borings formed in each part ensure axial and angular alignment of the various parts of stacking. The unit is solidarized by injection of an adhesive under pressure. Suitable openings make it possible to connect by laser welding the conducting elementary parts to the wires located in the sheath to form the annular contacts of the terminal.
