摘要:
A method is provided for screening the sensitizing properties of chemical compounds. The method is based on keratinocytes or cells that share important hallmarks of these cells, but other components e.g. proteins could also be used. This method is of importance for several conditions, including but not limited to allergic contact dermatitis (ACD), drug hypersensitivity reactions (DHRs) and autoimmune diseases.

Amyloid β (Aβ) aggregates are considered as possible targets for therapy and/or diagnosis of Alzheimer disease (AD). It has been previously shown that curcumin targets Aβ plaques and interferes with their formation, suggesting a potential role for prevention or treatment of AD. In the present invention, curcumin-derivatives with improved physicochemical properties were synthesized and a "click chemistry" as well as a conventional liposome preparation method, were used to generate nanoliposomes decorated with the curcumin derivatives. These derivatives were designed to maintain the planar structure required for interaction with Aβ, as directly confirmed by Surface Plasmon Resonance experiments. Surface Plasmon Resonance experiments, measuring the binding of flowing liposomes to immobilized Aβ1-42, indicated that the liposomes exposing curcumin derivatives have extremely high affinity for Aβ1-42 fibrils (1-5 nM), likely because of the occurrence of multivalent interactions. The present invention describes the synthesis of the curcumin derivatives and the preparation and characterization of new nanoliposomes with a very high affinity for Aβ1-42 fibrils, to be exploited as vectors for the targeted delivery of new diagnostic and therapeutic molecules for AD.
摘要:
To carry out a transparent test of integrated circuits, all of the state registers and input/output registers that determine the applications' execution context are included into circular scan paths having the output of the last stage connected to the input of the first stage. Before the test, the contents of the registers are shifted via the scan path into a RAM. After the test, the saved contents of the registers are reloaded from the RAM to the registers via the scan path.

PCT No. PCT/GR94/00021 Sec. 371 Date May 1, 1995 Sec. 102(e) Date May 1, 1995 PCT Filed Sep. 2, 1994 PCT Pub. No. WO95/06908 PCT Pub. Date Mar. 9, 1995The present invention relates to a fail-safe control interface including branches for providing signals having a safe state or a non-safe state. Each branch comprises inputs for receiving at least two binary control signals (Si, Si*); a source of a non-safe state (Fe) connectable through a basic chain of elements (14, 15) to an output (Oi) when the control signals realize a predetermined combination; a concurrent checker (17) providing an error detection signal (g1, g2) if the inputs of a pair of its inputs are at predetermined states; and means (14*) for providing a first input of said pair of inputs with a signal corresponding to the state of said output and the second input of said pair of inputs with a signal corresponding to the output of a duplicate chain of the basic chain, this duplicate chain reacting like the basic chain in response to the control signals.

Technique de contrôle transparent de circuits intégrés. Elle permet de contrôler les circuits intégrés sans perdre le contexte d'exécution des applications, et s'applique à deux types de blocs, à savoir d'une part les blocs combinatoires et séquentiels, et d'autre part les mémoires vives et les fichiers de registres. Pour le premier type de bloc, on a mis au point une technique de stockage, de contrôle et de restitution. Elle met en oeuvre une trajectoire circulaire de balayage et consiste à transférer, par l'intermédiaire de la trajectoire de balayage, le contenu de divers registres aux entrées de données d'une mémoire vive, à stocker le contenu des registres dans la mémoire vive, à effectuer le contrôle, à transférer les données stockées à la trajectoire de balayage, et à les transférer aux registres correspondants. Pour le second type de bloc, on a mis au point une technique de contrôle transparent permettant de contrôler les mémoires vives sans en détruire le contenu initial. A cette fin, on a mis au point une technique permettant de dériver des processus de contrôle transparent de mémoire vive. La mise en oeuvre de ces processus de contrôle peut s'effectuer selon des techniques d'autocontrôle ou des techniques à trajectoire de balayage. Les processus de contrôle transparent se composent d'un processus de prédiction ou d'initialisation de signatures ou d'un processus de contrôle transparent de base. Le processus de contrôle par prédiction de signature est obtenu par l'élimination de toutes les opérations d'écriture du processus de contrôle transparent de base. On peut également éliminer les opérations de lecture de sorte que les données de lecture ne soient pas introduites dans la méthode de compression de sortie. Cette technique évite tout masquage d'erreurs dû aux erreurs produites à la fois lors du processus de contrôle par prédiction de signature, et lors du processus de contrôle transparent de base. Ce dernier est obtenu selon plusieurs étapes de transformation à partir d'un processus de contrôle normal
摘要:
The present application describes a drug dispensing device. The device is comprised of an armband, a rigid housing, made of polymeric or composite material, with any geometric shape, which separates in two along the longitudinal axis, incorporating therein a capsule containing a concentrated fluid whose geometric shape allows its storage within said housing. The centre of the top of one of the capsule faces contains a valve which, upon being actuated by at least one flexible tab, by pressing the mouth of the user, is expelled from the inside of the capsule, allowing him to suck the concentrated fluid contained therein. In this way, the device allows the user to correct the reference values quickly and effectively and thus regain the sense of physical safety while practicing sports in extreme situations or while practicing activities in water environments.
