Abstract: Cells derived from human umbilical cords are disclosed along with methods for their therapeutic use. Isolation techniques, culture methods and detailed characterization of the cells with respect to their cell surface markers, gene expression, and their secretion of trophic factors are described.

Abstract: The present invention is directed to methods and compositions for repairing damaged myocardium using human cardiac tissue-derived cells. In particular, the present invention provides methods and compositions for repairing damaged myocardium using expanded human cardiac tissue-derived cells that do not express telomerase.

Abstract: A temperature-sensitive resistance element comprises an alumina substrate having terminals and a sinuous temperature-sensitive resistance layer thereon. The layer and terminals are formed of electroplated palladium which has been recrystallized.

Abstract: A divider is made from a layer (1) of conducting material carried on an insulating support (2). A first slotline (3) is formed in the conducting layer extending from a first input port (A). A second slotline (5, 6, 7) is formed at right-angles to and spaced from the end of the first slotline (3), extending between first and second output ports (C and D). Third and fourth slotlines (8, 9) extend from the end of the first slotline (3) to points on the second slotline spaced by a distance which is electrically short compared with one-quarter of a wavelength. The third and fourth slotlines (8, 9) are an odd multiple of quarter-wavelengths long. A resistor (10) is connected across the second slotline substantially midway between the ends of the third and fourth slotlines, and has a resistance such that the output ports are correctly terminated.

Abstract: An improved tobacco-smoke filter or filter material contains granules of porous activated carbon to which has been applied a nitroxide of the group consisting of the nitroxide 4-oxo-2,2,6,6-tetramethylpiperidino-oxy, the nitroxide 1-nitronyl-3-oxyl-4,4,5,5-tetramethyl-2-phenyldihydroimidazole and mixtures thereof. The carbon may be loaded with 0.5 to 25%, suitably 1.0 to 15%, by weight of the nitroxide. Advantageously such a filter has provision for filter ventilation. For instance, in a triple filter with a center section containing the treated carbon, the said center section and/or the section upstream thereof is ventilated.
