Abstract: Brain glucose utilization can be increased by administering an agent that improves central nervous system insulin sensivity. By improving the central nervous system insulin sensivity and increasing brain glucose utilization, a ge- related memory loss and dementia can be prevented and/or reduced. The improvement in brain glucose utilization is independent of treatment for Typ e II diabetes. Among the central nervous system insulin sensitizers that can b e administered to increase brain glucose utilization are thiazolidinediones, including troglitazone, rosiglotazone and pioglitazone. Other useful compoun ds include oxyzolidinediones, including JPP501, and non-chiral acyclic agents, including GL 262370, and substituted 4-hydroxy-phenylalcanoic acid derivativ es which are PPAR gamma receptor activators. All of these agents act on the nuclear receptor PPAR gamma. In a preferred embodiment, the agents are administered in the form of prodrugs which are designed to cross the blood brain barrier.

Title: Organization of test cases
Inventor: SLUIMAN HARM
IPC: G06F9/44
Filed: 2001-12-27
Abstract: Embodiments of the invention include a test case that is encapsulated defining its relationship with other such encapsulated test cases. An encapsulated test case may be explicitly associated with one or more parent test cases. Additionally, or alternatively, a test case embodying aspects of the present invention may be explicitly associated with one or more child test cases. Through such explicit relationships between test cases a complex hierarchical structure of test cases can be quickly and efficiently created. Further aspects of the invention, which may be incorporated in some embodiments, include an encapsulated test case which, when associated with other encapsulated test case, results in an explicit tree-like hierarchical structure of test cases being defined. In further embodiments of the present invention, a test case (encapsulated or conventional) may be associated with a test case association property. The test case association property explicitly defines the relationship between a parent test case and a child test case. That is, the test case association property defines a bi-directional (i.e., two way) association between a parent and child test case. In one embodiment, the test case association property is embodied in an object (such as, for example, a JAVA language object). In this embodiment, a selected test case may be associated with one or more test case association property objects wherein each test case association property object describes the relationship for only one parent test of the selected test case and the relationship for only child test case of the selected test case.

Abstract: L'invention concerne un procédé d'attaque électrochimique pour réaliser des pores de filtre fins dans une ébauche en silicium à dopage n ou p, lesdits pores présentant une section transversale approximativement constante. L'ébauche est connectée sous la forme d'une anode ou d'une cathode, puis plongée dans une solution d'attaque, dans laquelle est placée une contre-électrode servant à produire un courant d'attaque, et enfin soumise à l'action de la lumière, ce qui provoque la formation de porteurs minoritaires dans l'ébauche. Le taux de production des porteurs minoritaires est régulé par l'intermédiaire de l'exposition à la lumière, de sorte qu'il diminue d'autant plus que l'attaque progresse, c'est-à-dire d'autant plus que la profondeur des pores augmente.
