  • Publication number: 20180000066
    Abstract: The present invention relates to a platelet protection solution (PPS) having an amount of one or more ?-galactosidase inhibitors with or without an amount of one or more sialidase inhibitors, and optionally one or more glycan-modifying agents; and one or more of PPS components that include a salt, a citrate source, a carbon source, or any combination thereof.

  • Publication number: 20170370952
    Abstract: The present invention relates to a reconstitution solution for spray dried plasma having a non-anticoagulant compound that does not bind calcium. When the reconstitution solution of the present invention is mixed with spray dry plasma, the reconstituted plasma mediates platelet adhesion and aggregation about the same as or greater than the starting plasma prior to spray drying. The present invention also relates to an assay for determining platelet adhesion and aggregation using microfluidic flow cell system having a shear flow. The assay assesses labeled whole blood samples having reconstituted plasma having spray dried plasma and a reconstitution solution; platelets; and red blood cells. After inducing a shear flow under conditions suitable for clot formation, coverage area of the platelets, intensity of the platelets, morphology, or a combination thereof is detected to determine platelet accumulation (e.g., platelet adhesion and aggregation).

  • Publication number: 20170270197
    Abstract: Computer-implemented systems and methods are disclosed to interface with one or more storage devices storing a plurality of documents, wherein each of the plurality of documents is associated with one or more tags of one or more predefined hierarchies of tags, wherein the one or more hierarchies of tags include multiple dimensions. In accordance with some embodiments, a method is provided to identify one or more documents from the data storage devices. The method comprises acquiring, via an interface, a selection of one or more tags of the one or more predefined hierarchies of tags. The method further comprises identifying one or more documents from the data storage devices in response to the selection, the identified one or more documents having tags that have a relationship with the selected tags, and providing data corresponding to the identified documents for displaying in the interface.

  • Publication number: 20170046235
    Abstract: A system restores a user interface (“UI”) state. The system receives an action performed by a user that interacts with a UI, and determines a transaction based on the action, where the transaction is configured to modify a model corresponding to the UI. The system stores a first UI state of the UI and a first model state of the model, and then commits the transaction. The system subsequently determines to undo the transaction based on a first user interaction. The system then restores the UI to the first UI state and the model to the first model state. In one embodiment, the first model state is restored before undoing the transaction, while the first UI state is restored after undoing the transaction.

  • Publication number: 20160000064
    Abstract: The present invention relates to methods and compositions for reducing sialidase activity and inhibiting bacterial proliferation of one or more bacteria in a platelet product preparation from one or more donors. In general, the method includes contacting the platelet product preparation with an amount of a sialidase inhibitor, to thereby obtain a sialidase inhibitor-treated platelet product preparation. Sialidase activity is reduced and the proliferation of one or more bacteria is inhibited, as compared to a platelet product preparation not subjected to the sialidase inhibitor treatment.
