摘要:
Monoclonal antibodies immunospecific for the neutrophil chemotactic factor, IL-8, have been humanized by reshaping the variable regions to conform more closely to human counterparts. These antibodies are useful in immunoassays to detect IL-8 and as ligands on immunoaffinity columns for purification of human IL-8. In addition, the humanized antibodies have an antiinflammatory effect in patients.
摘要:
The present invention discloses a reshaped human antibody against human IL-8 comprising:(A) L chains each comprising:(1) a human L chain C region; and,(2) an L chain V region comprising a human Lchain FR, and an L chain CDR of mouse monoclonal antibody against human IL-8; and,(B) H chains each comprising:(1) a human H chain C region; and,(2) an H chain V region comprising a human Hchain FR, and an H chain CDR of mouse monoclonal antibody against human IL-8. Since the majority of this reshaped human antibody originates in human antibody and the CDR has low antigenicity, the reshaped human antibody of the present invention has low antigenicity to humans, and can therefore be expected to be useful in medical treatment. The present invention further discloses polynucleotides which encode reshaped antibodies against IL-8, as well as host cells and methods to produce these antibodies.
摘要:
A reshaped human antibody is characterized as having the same binding affinity for IL-8 as a chimeric antibody but with low immunogenicity in comparison. The reshaped antibody has the following elements: a human L chain C region or a human L chain FR and an L chain CDR from a mouse monoclonal antibody against human IL-8 and a human H chain C region or a human H chain FR and an H chain CDR of mouse monoclonal antibody against human IL-8. Since the reshaped human antibody has low immunogenicity to humans, it is suitable for use in medical treatment of a variety of medical conditions.

In a chip-size package, an insulator tape is formed with a conductive wire having a wider section which is greater in width than other sections of the wire and a conductive bump connected to the wider section of the wire. The insulator tape is further formed with a first plurality of slits arranged on one side of the wider section of the wire and a second plurality of slits arranged on the other side of the wider section. An integrated circuit chip is provided having a conductive pad connected to the copper bump.

An isolated converter with a reduced size is disclosed. A small-sized multilayer sheet transformer includes a multilayer circuit board composed of a plurality of sheet substrates, coil patterns of primary and secondary coils disposed coaxially on the sheet substrates, and a core member disposed in a coil pattern unit formed of the coil patterns. In this multilayer sheet transformer, a coil pattern formed on the outer surface of the top layer and a coil pattern formed on the outer surface of the bottom layer are for the same coil on either the primary or secondary side. In the case where the coil patterns formed on the outer surfaces of the top and bottom layers of the multilayer sheet transformer are for the primary coil, an isolation gap is formed between the multilayer sheet transformer and a circuit on the secondary side to prevent an electrical breakdown between the primary and secondary sides. In the case where the coil patterns formed on the outer surfaces of the top and bottom layers of the multilayer sheet transformer are for the secondary coil, an isolation gap is formed between the multilayer sheet transformer and a circuit on the primary side to prevent an electrical breakdown between the primary and secondary sides.

A binocular telescope provided with a pair of left and right lens-barrels respectively containing optical systems, a first guide shaft for supporting these lens-barrels in such a manner that the lens-barrels can slide in a direction perpendicular to the optical axes of the optical systems and can rotate, a second guide shaft for restraining the relative tilt of the lens-barrels around this first guide shaft in such a manner that the optical axes of the left and right optical systems become parallel to each other, a first rib for holding both ends of the first guide shaft by fitting upper and lower covers to each other, and a second rib for restraining the tilt of the optical axes of the entire lens-barrels around the first guide shaft.

A prism optical system provided with: a first prism on which a light ray coming from an objective lens is incident; a second prism on which the light ray coming from this first prism is incident, and from which this incident light ray is emitted; and a plate-like member which is interposed between the aforesaid prisms so as to provide a predetermined air space therebetween and which has a diaphragm opening and a light blocking portion. Further, an uneven portion, which consists of depressions and projections and has a serrate section, for preventing light rays, which have been reflected from the surface of the light blocking portion of this plate-like member, from entering a field stop is provided in the light blocking portion thereof. Thereby, occurrences of ghosts and flares due to stray light are prevented. Moreover, ghosts and flares are reduced.

An interpupillary distance adjusting mechanism for use in a binocular telescope, having a pair of lens-barrels which contain lens optical systems, respectively, and are placed in parallel with each other. The interpupillary distance adjusting mechanism further has first and second guide shafts, which slidably guide the pair of lens-barrels in a direction substantially perpendicular to the direction of the optical axes of the lens optical systems, interpupillary distance adjusting springs for pushing the pair of lens-barrels in a sliding direction, and an interpupillary distance adjusting cam which can adjust an interpupillary distance by sliding the pair of lens-barrels along the guide shafts as the result of undergoing a pushing force from the interpupillary distance adjusting spring, of converting a part of the pushing force in a direction which intersects the sliding direction, and of moving the pair of lens-barrels by pushing the pair of lens-barrels against the first guide.
