    摘要: In an ultrasound imaging system, ultrasound echoes representing vessel walls are distinguished from ultrasound echoes from blood by using a classifier which employs the mean and variance of the raw data of gray intensities as acquired directly from an ultrasound scanner detector. In a specific embodiment, the statistical parameters of mean and variance are determined in the course of real-time processing and prior to attempted classification and then are used as parameters representing the true image as acquired.

    摘要: A method for increasing the stability and uniformity of a PEGylated G-CSF polypeptide having at least one PEG moiety attached to the epsilon amino group of a lysine residue or the N-terminal amino group and at least one PEG moiety attached to a hydroxyl group, comprising subjecting the polypeptide to an elevated pH of above 8.0 for a period of time suitable to remove PEG moieties attached to a hydroxyl group, and reducing the pH to about 8.0 or lower; as well as PEGylated G-CSF polypeptides and compositions produced according to the method and methods for increasing neutrophil levels in a patient using the PEGylated G-CSF polypeptides and compositions.
