Abstract: Techniques for managing access privileges in a data processing system include obtaining a plurality of rules for granting and/or denying privileges to a first actor to perform at least one action on a first instance of a first data entity of data entities; identifying, from among attributes of the first data entity, a first attribute whose values are used by one or more of the plurality of rules; obtaining, from a user or from at least one data store, a first value of the first attribute; identifying, using the first value and from among the plurality of rules, a first rule that depends on the first value; generating a graphical user interface (GUI) including a visual rendering of at least some of the plurality of rules, the visual rendering emphasizing the first rule identified using the first value of the first attribute; and displaying the generated GUI to the user.

Abstract: Methods for treating malaria are provided, the treatment comprising the step of removing malaria-infected red blood cells from the patient's blood. Blood is drawn from the patient's circulatory system and circulated through a blood purification device that selectively eliminates the infected red blood cells from all other blood's components and replaces the cleansed blood back into the patient's circulatory system. A blood purification device, which is useful to perform the therapeutic methods of the invention, is also provided. The device leverages the magnetic properties of the hemozoin contained within the infected red blood cells and comprises one or more separation chambers (4) though which blood flows through a high-gradient magnetic field generated by an array of wires (5) separated from the chambers and not in contact with the patient blood.
