Abstract: This application discloses that inositolphosphoglycans (IPGs) can be obtained from basophils, eosinophils and mast cells and that allergen stimulation of these cells results in IPG release. It also shows that IPGs are second messengers for allergic stimulation as the addition of some types of purified IPGs to non-allergen stimulated cells resulted in histamine release or degranulation. Thus, IPG antagonists can be used for the treatment of conditions (especially allergy and asthma) mediated by the release of IPGs from mast cells, basophils or eosinophils. Preferred IPG antagonists include anti-IPG antibodies, inhibitors of the enzyme GPI-PLD and competitive antagonists.

Abstract: The invention provides a wet-type sprinkler system by which the water damage caused when a sprinkler heads function in a wrong way with ensuring a quick extinguishing operation at the time of fire. A suction pipe is provided for the system so as to communicate with a top part of a secondary pipeline 24 of a feed pipe arrangement 20 forming a water supply line from a water supply unit 16 to sprinkler heads 12. Further, a suction unit (an electromagnetic valve 54 and a suction pump 50) for sucking the air in the secondary pipeline section 24 from the top part of the secondary pipeline section 24 is provided onto the suction pipe 52. The suction pipe 52, the suction pump 50 and the electromagnetic valve 54 constitute a negative-pressure-securing section. In the secondary pipeline 24, which is filled with water in a normal condition water is negatively pressurized by the suction operation of the suction unit. The negatively pressurized state of the water is ensured under a normal condition. Thus, water in the secondary pipeline is prevented from unnecessarily being discharged when the sprinkler heads 12 function in a wrong way.  <IMAGE>

Abstract: Image processing operations are used to improve images that include visual artifacts generated by calibration markers used in intrinsic calibration of an X-ray image. Artifacts introduced by opaque or semi-transparent calibration markers may be completely or partially removed from the image. More particularly, artifacts caused by opaque calibration markers are removed by changing the pixels corresponding to the projections of the calibration markers to blend in with pixels surrounding the calibration markers. Artifacts may also be generated with semi-transparent calibration markers. These artifacts may be eliminated from the image, while leaving intact the underlying image, by subtracting a constant offset from each marker projection.

Abstract: A wireless telecommunications system comprises a radio network layer for carrying mobile-specific signaling, and a transport layer for establishing user channels between system nodes over a transport network. The transport network is visible to the radio network layer only via a primitive interface through which it can request transport services. The invisibility of the transport network to the radio network layer makes the radio network layer independent of the underlying transport network and enables the use of different transport network technologies. The radio network layer signaling procedures and connections are mapped with the underlying transport layer signaling procedures and connections by using binding information at one end of the connection leg, which is exchanged between the network and transport layers through a primitive interface, and used to "identify" the radio network layer and the transport layer connection setup signaling carried out between the nodes.

Abstract: A process is described for the synthesis of 2-hydroxyphenylalkyl ketones, by means of catalytic rearrangement of phenolic esters. This process is characterized by the use, as catalysts, of crystalline aluminosilicates of the pentasyl type having predefined values of silica/alumina ratio, grain size, surface area and porosity, and containing between 10 wt% and 40 wt% of finely ground alumina as bonding agent. The rearrangement thus catalyzed involves a high conversion of the phenolic ester, a high orthoselectivity and a low formation of phenolic by-products, thus enabling the formation of the end product in high yields. In particular, the process applies to the synthesis of 2-hydroxyacetophenone.
