Title: Procede et dispositif permettant de detecter, de localiser et d'analyser des composes chimiques par activation de particules subatomiques
Inventor: MAGLICH BOGDAN C
IPC: G01V5/14
Filed: 1999-02-17
Abstract: Dispositif et procédé permettant de détecter, de localiser et d'analyser, par activation de particules subatomiques, des composés chimiques contenus dans un objet à tester. Une source d'excitation excite une cible de façon à produire simultanément des faisceaux dont chacun est constitué de certaines espèces subatomiques, tels que neutrons rapides et particules alpha. L'objet à tester (et les composés chimiques qu'il contient) est irradié par les neutrons rapides, ce qui stimule l'émission de rayons gamma instantanés. Des détecteurs gamma et alpha sont positionnés par rapport à l'objet à tester et à la cible de façon à détecter les rayons gamma instantanés et les particules alpha émis en coïncidence substantielle, et la relation physique connue entre les faisceaux est utilisée pour localiser spatialement le composé chimique activé. Les spectres d'énergie dérivés des détecteurs gamma sont filtrés de façon à éliminer tous les artefacts spectraux non pertinents, ce qui 1) permet de créer une pluralité de canaux de coïncidence parallèles ; 2) diminue le traitement de signaux ultérieur nécessaire ; et 3) augmente globalement la précision et le rendement des processus d'identification et d'analyse du composé chimique. L'invention concerne également un mode de réalisation multifaisceau/multicible, qui permet une localisation spatiale encore plus précise. Elle concerne aussi un procédé qui permet d'étalonner et d'évaluer l'efficacité du système avec divers paramètres d'analyse.

Title: Sterol glucosides in disease
Inventor: SHAW CHRISTOPHER A
IPC: G01N33/92
Filed: 2000-11-03
Abstract: The etiology of various age-related neurological diseases remains unknown.  Sporadic forms of Alzheimer's, Parkinson's, and Lou Gehrig's disease have been linked to environmental factors that cause neuronal cell death by either by excitotoxicity or by inducing oxidative stress. Our recent studies have demonstrated that various compounds not previously associated with these diseases, i.e., methionine sulfoximine and sitosterol glucoside, appear to be neurotoxins, likely acting by excitotoxic mechanisms. For these compounds, the primary excitotoxic effect appears to involve glutamate release followed by NMDA receptor activation. Lactate dehydrogenase assays demonstrate that both compounds cause rapid cell death in vitro. In addition, both compounds appear to alter antioxidant defense mechanisms, acting particularly on levels of reduced glutathione (GSH). In vivo application of MSO has historically been linked to behavioral abnormalities, including seizures, in various species. Our recent experiments have demonstrated that mice fed cycad flour containing sitosterol glucoside have severe behavioral abnormalities of motor and cognitive function, as well as significant levels of neurodegeneration in cortex, hippocampus, spinal cord, and other CNS regions measured post mortem.   The combined weight of excitotoxic action, in concert to a decline in antioxidant defenses, induced by molecules such as methionine sulfoximine and sitosterol glucoside is hypothesized to be causal to neuronal degeneration in various neurological diseases.  Understanding the mechanisms of action of these and functionally related molecules may serve to focus attention on potential neurotoxins present in the human environment. Only once such molecules have been identified, can we begin to design appropriate pharmaceutical strategies to prevent or halt the progression of the age-related neurological diseases.        Key Words Glutamate, glutathione, excitoxicity, oxidative stress, methionine sulfoximine, sitosterol glucoside, ALS, Parkinson's disease, Alzheimer's disease, ALS-PDC.     Abbreviations ALS, amyotrophic lateral sclerosis; ALS-PDC, ALS-parkinsonism dementia complex; AMPA, .alpha.-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid; ATP, adenosine triphosphate; BSSG, .beta.-sitosterol-.beta.-D-glucoside; EAA, excitatory amino acid; GluR, glutamate receptor; GSH, glutathione; LDH, lactate dehydrogenase; MSO, methionine sulfoximine; NMDA, N-methyl-D-aspartate; ROS, reactive oxygen species; SOD, superoxide dismutase.

Patent CA-2327170-A1 (CA)
Inventor: BLOEMER MARK J
IPC: G02B6/122
Filed: 1998-04-02
Abstract: A novel SH generator based on a photonic band gap (PBG), mixed half-quarter- wave, periodic structure is described. Both energy output and conversion efficiencies are nearly three orders of magnitude greater than for bulk, pha se- matched devices of comparable lengths. Similiar results for a GaAs/AlAs semiconductor periodic structure are also found. These results have immediat e applications in frequency up- and down-conversion lasers, higher and lower harmonic generation, and Raman-type lasers, where either Stokes or anti-Stok es resonances can be enhanced or suppressed near the band edge. In general, the  underlying mechanism requires the fields to be strongly confined, allowing f or longer interactions times, increased effective gain lengths, and enhanced conversion efficiencies, although strong pump confinement alone can also result in significantly enhanced SH generation.

IPC: G01N15/10

Abstract: A method and apparatus for providing a zero dead time for flow analyzers, flow cytometers, and other measurement devices. A circular buffer is used to store data from a flow analyzer in a plurality of data storage areas, until it is convenient to implement more time consuming data processing procedures. User specified parameters, including sampling rate and/or sampling period, size and number of data storage areas, size of the circular or other buffer, signal-to-noise threshold, order of processing when a plurality of Digital Signal Processors (DSPs) is used, and fixed trailing distance, are used to provide flexible and convenient operation by a user.      The probability of missing a rare event occurring within the laser beam or other light beam of a flow analyzer or other measurement device is reduced to zero. Functional equivalents may be used in place of the circular buffer, for example, First In-First Out buffers which route data to a cache for potential re-reading and/or reprocessing or additional processing of data, cascading buffers, etc. Circular and functionally equivalent buffers permit sophisticated data processing in which preceding data (for example, data not meeting the S/N threshold) subsequently are re-analyzed for the possibility that the data are part of a developing event peak, such as a developing shoulder thereof, or part of a declining peak. In addition, logic and algorithms to permit re-examination and potential reprocessing of "old" subthreshold data is utilized to improve the SIN ratio of an event peak.
