  • Publication number: 20230090960
    Abstract: The present invention relates to the use of alkali hydroxide for the regeneration of apheresis columns for the affinity chromatographic removal of CRP and a method for the simplified regeneration of apheresis columns for the affinity chromatographic removal of CRP with the use of an alkali hydroxide solution and apheresis devices which are designed in such a manner as to be resistant to alkali hydroxide solutions and to allow the regeneration of apheresis columns for the affinity chromatographic removal of CRP in continuous operation.

  • Publication number: 20210308352
    Abstract: The present invention relates to an apheresis device (1) for the extracorporeal removal of C-reactive protein from blood of a patient, wherein the apheresis device is connectable to the blood circulation of the patient. The blood is pumped via a part of the extracorporeal circulation system (2) of the apheresis device (1) according to the invention to a cell separator (7) for separation of the blood into blood plasma and cellular components. Via a first outlet of the cell separator (7), the separated blood plasma is directed by means of a plasma line (8A) to an apheresis column (4) for affinity chromatographic removal of C-reactive protein from the blood plasma. After removal of the C-reactive protein from the blood plasma of the patient, said now treated blood plasma is combined with the cellular components of the blood via a plasma line (8B).

  • Patent number: 11023144
    Abstract: This disclosure relates generally to storage device, and more particularly to method and system for dynamically allocating front end ports in a storage device. In one embodiment, the method may include determining a need for re-allocating a set of servers being served by a first set of front end ports from among a plurality of front end ports of the storage device, evaluating remaining ports of the plurality of front end ports to identify a second set of front end ports to serve the set of servers, dynamically updating a configuration of each of the plurality of front end ports by emulating virtual worldwide names (vWWNs) of the first set of front end ports onto the second set of front end ports, and serving the set of servers from the second set of front-end ports based on the updated configuration.

  • Patent number: 10065133
    Abstract: The present invention provides phosphoryl choline derivatives of general formula (I), which are suitable to be immobilized on a solid support to provide a separation material of general formula (II), which bind with both high affinity and high specificity to a protein, more specifically to C-reactive protein and anti-phosphoryl choline antibodies. Said separation materials are particularly useful in the extracorporeal removal of C-reactive protein and anti-phosphoryl choline antibodies from a biological fluid of a patient for prophylaxis and/or treatment of immune dysfunctions and cardiovascular diseases. Also provided is a column that comprises the separation material of general formula (II), as well as a device containing the column. Formula (I), wherein variable X is selected from: —SH, —NHR3, —C?CH, —CH?CH2, —N3 and —CHO; the other variables are as defined in the claims: Formula (II), wherein variable “A” represents a solid support. “A” as well as the other variables are defined in detail in the claims.
