    摘要： The present invention provides a fluidized bed for dispensing small quantities of powders. The fluidized bed is made using a porous housing to permit injection and removal of fluid through the surrounding walls to improve the operation of the bed particularly for small particles of the group C size, including significantly reducing powder adhesion to the walls. In one aspect of the invention the fluidized bed housing is rotated about its longitudinal axis, which may be oriented at any suitable angle. A system for changing the volume of the bed is described as is a system for incorporating injection nozzles within the bed for constant agitation and prevention of powder adhering to the walls of the housing.

    摘要： The present invention relates to the discovery in mammalian cells, particularly human cells, of novel S-phase kinase associated proteins, p19 and p45, referred to herein as "Skp". As described herein, these proteins are components of the tumor cell-specific cyclin A/CDK2 complex and function to facilitate DNA replication. Interference with p45 function in vivo prevented entry into S-phase in both normal and transformed cells. Binding data indicated that p45 and p19 associate with each other in a binary complex. Moreover, p45 is required for p19 binding to cyclin A/CDK2.

In another embodiment, the melt spinning process of polyacrylonitrile is conducted by using imidazole type ion liquid as plasticizer, the process reduces environment pollution, is suitable for industrial production and the fiber produced thereby is improved in its strength. In yet another embodiment, polyacrylonitrile pre-oxidized fiber is produced by melt spinning, so low cost and controllable pre-oxidization of polyacrylonitrile can be achieved. In a further embodiment, high strength carbon fiber is manufactured by using polymer thickening agent. In another further embodiment, low cost and controllable pre-oxidization of polyacrylonitrile is achieved by conducting pre-oxidization before spinning, minimizing skin-core structure, so as to produce high performance carbon fiber, and reduce the production cost of carbon fiber greatly.

    摘要： Highly specific and novel methods for reversible hydrazone solid-phase extraction (rHSPE) are provided for glycan or glycopeptide isolation from proteins, peptides, and other contaminants for glycan and glycopeptide analysis. Glycans or glycopeptides in complex mixtures can be conjugated onto solid support or affinity or chemical tags via reversible hydrazone bond. The conjugation methods of the present invention are chemically specific and provide unique means for the removal of other non-glycan containing molecules in the complex sample before the glycans or glycopeptides are hydrolyzed and recovered for analysis. The hydrazone formation and hydrolysis of the novel methods allows for the analysis of glycans and glycopeptides. The hydrazide coating on the solid-phase surfaces are useful for surface glycan capture and on target glycan analysis. Uses of the information generated by the inventive methods for diagnosis and treatment are also disclosed.

    摘要： A method for improving the performance of a RAID under rebuild is disclosed. In one embodiment, such a method includes identifying a RAID requiring rebuild, such as by identifying a RAID having one or more failed storage-drive components. The method then automatically performs the following in response to identifying the RAID: the method identifies hot extents (i.e., extents most heavily accessed) in the RAID; the method migrates the hot extents from the identified failed RAID to a normal RAID not requiring rebuild, such as to an underused RAID; and the method rebuilds the failed RAID. The migration of the hot extents will ideally occur while the RAID is being rebuilt but may also be performed prior to the rebuild process. A corresponding apparatus and computer program product are also disclosed.
