Abstract: A vehicle window shade arrangement for at least partially shading the windshield of a vehicle, such as an automobile, having a dash with an upper surface and an elongated opening in the surface extending along the width of the windshield, the window shade arrangement comprising a shade rolled about a shade tube rotatably mounted below the upper surface of the dash; a shade extender-retractor for selectively unrolling the shade from the shade tube to an extended position at least partially shading the windshield, and rolling the shade about the shade tube to a retracted position not shading the windshield; and left and right elongated side supports disposed adjacent left and right sides, respectively, of the windshield. The shade is supported and concealed by the left and right side supports when not retracted. The shade extender-retractor may comprise a manual or powered drive arrangement for driving the shade to the extended and retracted positions.

Abstract: Azaanthracene-triones of the formula: ##STR1## (in which: R.sup.1, R.sup.2, R.sup.4 and R.sup.5 are the same or are different and each is a hydrogen atom or a lower alkyl group;R.sup.3 is a hydrogen atom, a lower alkyl group, a phenyl group or an amino-substituted phenyl group; andX is a --CH--, .dbd.N-- or --NH--, whereby the ring containing the group X is a benzene, pyridine or dihydropyridene ring)have antitumoral activity.

Abstract: A 16.7 kilodalton membrane protein which is produced in mature, but no early-stage, T cells has been discovered. The protein has four distinct amphipathic domains, each having an amino acid composition which is predictive of an alpha helical structure that would be stable in a lipid bilayer. Each of these regions is flanked by a relatively polar domain whose amino acid sequence is predictive of .beta. pleat peptide regions. An antibody specific against one of the polar domains can be used to discriminate mature T-cells in a mixed-cell sample.
