摘要:
Disclosed herein is a class of linkable tetrasaccharide compounds that includes the amino phenyl glycoside of sialyl Lewis X (SLeX) and related analogs. These compounds have conjugatable nucleophilic groups, making them useful in preparing multimeric SLeX compositions. In particular, the disclosed SLeX compounds can be used to prepare selectin binding ligand conjugates by linking them to a reporter moiety, such as a contrast agent, a radiodiagnostic agent, or a cytotoxic or chemotherapeutic agent. The SLeX compounds and conjugates of the invention exhibit binding to selectin that is similar to native Sialyl LeX, and are, therefore, useful for diagnosing and treating selectin-mediated disorders and related conditions.

An embodiment for analyzing a body-part of a patient is proposed. A corresponding data-processing method includes the steps of providing a sequence of input images representing the body-part over an analysis period, each input image including a set of input values each one being indicative of a response to an interrogation signal of a corresponding location of the body-part at a corresponding acquisition instant included in the analysis period, associating an analysis function of time with each one of a set of selected locations, the analysis function modeling a trend of the input values of the selected location in the sequence of input images, and providing a reference function of time for the analysis functions; in an embodiment, the data-processing method further includes comparing the analysis function of each selected location with the reference function to determine a polarity trend representing a trend over the analysis period of a polarity of a divergence between the analysis function of the selected location and the reference function, and creating a parametric image including a parametric value for each selected location, the parametric value being indicative of the polarity trend of the selected location.

An embodiment is proposed for analyzing a body-part. A corresponding embodiment of a data-processing method includes the steps of providing a parametric map including a plurality of parameter values each one characterizing a corresponding location of the body-part, and determining at least one statistical indicator of at least one distribution of a plurality of analysis parameter values corresponding to selected analysis locations, each statistical indicator being indicative of a condition of an analysis region of the body-part defined by the analysis locations. In an embodiment, the step of determining at least one statistical indicator includes, for each distribution of the analysis parameter values, determining a saturation value partitioning an ordered sequence of processing parameter values, corresponding to selected processing locations at least including the analysis locations, into a first subset and a second subset consisting of a number of the processing parameter values being determined according to a predefined auto-scaling percentage, generating an auto-scaled map including, for each processing location, an auto-scaled value being equal to the corresponding processing parameter value if included in the second subset, or the saturation value if the corresponding processing parameter value is included in the first subset, and determining the at least one statistical indicator from the auto-scaled values corresponding to the analysis locations.

The present invention relates to a gasket (7) for a pre-filled syringe 1 into which liquid (3) is charged, wherein a peripheral side surface of the gasket (7 a) that is in contact with an inner surface of the syringe barrel (2) is provided with a restriction (8), the bottom surface (7c) of the gasket (7) that is not in contact with the liquid (3) is formed into a tapered shape (10) and the gasket (7) has a hardness comprised from 57 to 60 when measured by a JIS hardness meter.
摘要:
Injectable aqueous suspension of microbubbles filled with a biocompatible gas and a method of preparation thereof. At least 10% of the total volume of gas contained in the microbubbles is contained in microbubbles with a diameter of 1.5 μm or less. The microbubbles can be obtained by preparing an emulsion comprising an aqueous medium, a phospholipid and a water immiscible organic solvent. The emulsion is then freeze-dried and then reconstituted in an aqueous suspension of gas-filled microbubbles.
