Abstract: et effet a été attribué à l'inhibition du complément, mais l'héparine présente également d'autres activités pouvant diminuer l'ischémie-reperfusion. Afin d'analyser ces mécanismes plus avant, nous avons comparé l'héparine et une héparine non anticoagulante O-désulfatée à activité anti-complément largement réduite. Administrée lors de la reperfusion de l'artère coronaire dans un modèle canin d'infarctus du myocarde, à la fois l'héparine et l'héparine O-désulfatée réduisent de manière égale l'adhérence de neutrophiles à l'endothélium de l'artère coronaire ischémiée et reperfusée, l'afflux de neutrophiles dans le myocarde ischémié et reperfusé, la nécrose myocardique et la libération de créatine kinase dans le plasma. L'héparine et l'héparine O-désulfatée empêchent également un dysfonctionnement de la relaxation coronaire dépendant de l'endothélium à la suite d'une lésion ischémique. En outre, l'héparine et l'héparine O-désulfatée inhibent la translocation du factllules endothéliales humaines et réduisent la liaison ADN NF-.kappa.B dans l'endothélium humain et le myocarde de rat ischémié et reperfusé. Ainsi, l'héparine et l'héparine non anticoagulante diminuent la lésion d'ischémie-reperfusion en interrompant de multiples niveaux de la cascade inflammatoire et, selon une nouvelle observation, les héparines inhibent l'activation du facteur de transcription proinflammatoire NF-.kappa.B.

Patent CA-2412040-A1 (CA)
Title: Attenuation devices
Inventor: JANSSEN ADRIAN P
IPC: G02B6/34
Filed: 2002-11-15
Abstract: In one embodiment of the invention, an optical attenuation device has an input/output 6 on which a multiplexed optical input stream is received. A  multiplexer/demultiplexer (MUX/DEMUX) (2) separates the received stream into individual optical signals on individual channels and has an output/return path (12) from the MUX/DEMUX (2) for each of the channels. Reflector means (4) in each output/return path (12) reflects all or a proportion of the optical signal on the respective channel back along the output/return path (12) to the MUX/DEMUX (2). At the MUX/DEMUX, the optical signals are combined into a multiplexed stream which is output on the input/output (6). In an alternative embodiment, the device has first and second MUX/DEMUX (2, 20), an output path (12) from the first MUX/DEMUX  (2), attenuation means (40) at the end of each output path (12) and return paths (120) from the attenuation means (40) to the second MUX/DEMUX (20). The attenuation means attenuates the optical signals on the respective channels, and the attenuated signals are combined into a multiplexed stream at the second MUX/DEMUX (20). Both embodiments achieve attenuation of multiplexed optical streams by attenuating the component optical signals of the stream in parallel.

Title: Radiotherapeutic apparatus comprising multileaf collimator
Inventor: ALBER MARKUS
IPC: G21K1/02
Filed: 2001-12-13
Abstract: An optimisation method for a fluence pattern to be provided via a radiotherapeutic apparatus comprising a multi-leaf collimator comprises an iteration of a progressive solution (such as a gradient approach) of the fluence profile, at least some iterations including a weighted penalty function which varies between solutions favoured by the collimator design and solutions not so favoured, later iterations including the penalty function at a greater weight. Thus, the penalty function represents locally preferred solutions derived from the constraints of the multi-leaf collimator (MLC). As the iteration progresses, the greater weight assigned to the penalty function drives the method towards a solution which is possible given the MLC  constraints. However, the lesser weight attached in the early stages of the iteration allows the method to settle towards a genuinely preferred solution.  Overall, therefore, the method migrates towards a theoretically ideal solution and then diverts to a nearby practically possible solution. In this way, a solution is obtained which can be put into practice but is close to a theoretically ideal solution, i.e. a solution that would be preferred in the absence of MLC constraints.

Abstract: An RF power oscillator for contactless card antennas shapes a carrier signal at the operating frequency utilizing a delay circuit having a number of taps for delaying the carrier signal by different lengths of time. The delayed signals are input into a buffer and output through resistors to a node coupl ed to the antenna. The resulting waveform for a square wave input signal, and equal-length delay taps, is a trapezoidal wave output. Any input wave form c an be shaped in a variety of ways depending upon the combinations of delay taps used. Since the buffer drivers for each delayed wave switch state at slightl y different times, the amplitude and bandwidth of emitted electromagnetic interference (EMI) is reduced for the transmission circuit.

Abstract: A trim operating wire 22 connected to a trim operating lever which can swing a nozzle, capable of adjusting the jet direction of jet water, downwards from an ordinary direction and can return the nozzle into the ordinary direction when the grip thereon is released has a structure in which one end of a pull wire 53 which is thin and rich in flexibility is connected to the trim operating lever, the other end of the pull wire is connected to one end of a push wire 57 which is thick and poor in flexibility through a push-pull converter 56, the other end of the push wire is connected to a steering nozzle 21, and the push-pull converter is disposed in a craft body at a position directly under or on the bow 24 side of a steering handle 14. The length of the pull wire connecting between the push-pull converter and the trim operating lever can be made short, and the push wire can be made long. As a result, even where the pull wire which is thin and rich in flexibility is disposed in the state of being bent at several portions thereof, the sliding resistance of an inner wire of the pull wire is small, and enhancement of operability can be contrived.
