It has now been discovered that certain mutant forms of pro-urokinase, such as so-called pro-UK mutant \u201cM5\u201d -, perform in the manner of pro-UK in lysing \u201cbad\u201d blood clots, while sparing hemostatic fibrin in the so-called \u201cgood\u201d blood clots. A user may wish to buy a song that is currently playing on the vehicle digital radio. In addition, a method is provided for manufacturing the foaming composition in which the particles are heated and an external pressure exceeding atmospheric pressure is applied to the soluble foaming particles. Variations of material refractive indices, physical dimensions, andor optical mode distributions with temperature may at least partly compensate one another to yield the designed temperature dependence. A plurality of strip conductors 1262 overlap with drawing lines 121 arranged to transmit data signals to data signal lines 111 with an insulating film 132 sandwiched therebetween, and the plurality of strip conductors 1262 are electrically connected by connecting portions 1263, 1264 and 1265 having portions which do not overlap with the drawing lines.
