An improved method for assaying for cancer by detecting .beta.-linked galactose moieties associated with cells is disclosed wherein a label specific for such moieties is added to the cells and subsequently sensed.

An enzymatic noninvasive method for detecting cancer in mammalian tissue is disclosed. This method comprises incubating exfoliated cells from mammalian tissue suspected of containing cancerous cells, and assaying them for galactosyl transferase activity. The level of galactosyl transferase activity has been found to be significantly altered in cells from cancerous tissue as compared to the level in cells from normal tissue.

There is disclosed a novel compact power oscillator which is normally quiescent until applied to a load, to produce, under load, a unique waveform which has a unique application to self-protective devices and medical uses. The oscillator includes a high gain inverting amplifier, preferably a Darlington pair constituted by a germanium output transistor driven by a small signal transistor, a transformer, a D.C. source such as a battery, and a pair of output electrodes.

This disclosure is concerned with novel techniques and circuit configurations for rendering high gain operational amplifiers and related differencing amplifiers adaptable for use with very low impedance signal sources to permit amplification of low-power signals with ultra-low noise, high D. C. stability, high gain, and wide frequency response, through development of the signal current as a very small increment on a much larger pre-existing current forced in opposite directions through an electr...

This invention discloses a method of using galactose-binding lectins, such as Ricinus communis agglutinin I (RCA.sub.I), to kill cancer cells. RCA.sub.I has been found to severely weaken certain types of cancer cells, such as bladder carcinoma. This weakening can kill substantial numbers of cancer cells. In addition, it is possible to attach RCA.sub.I to other substances which impose stress on cells, such as cytotoxic drugs or enzymes that catalyze exothermic reactions, which can kill weakened c...

A printer for creating specialty-sized prints where media is advanced through the printer along a media advancement path, the printer including a housing, a printing mechanism disposed in the housing and configured to place a desired print on the media, a cutter mechanism disposed in the housing adjacent the printing mechanism and configured to cut the media transverse to a media advancement direction through the cutter mechanism, and a slicing mechanism disposed in the housing adjacent the prin...

A method for creating photographic-quality prints and prints produced by these methods are disclosed. The prints generally comprise three layers: a transparent carrier; an image, and a particle-based undercoat. The transparent carrier comprises a substrate for receiving an image. The image can be produced by inkjet, electrostatic, or other imaging methods, including reverse printing methods. The particle-based undercoat layer is applied to the image containing side of the transparent carrier. Al...

A printer for creating specialty-sized prints includes a printing mechanism, a cutter mechanism and a slicing mechanism. A media web or sheet is fed into the printer and is advanced by a media advancement mechanism in a media advancement direction. The cutter mechanism cuts the media transverse to the media advancement direction. The slicing mechanism slices the media parallel to the media advancement direction. The slicing mechanism includes a cam positioned on a camshaft and a slicer module. T...

Throughput of ink jet printers can be increased by using multiple print heads, each of which independently prints an image or text on a continuous roll of print media. Independently controlled printer carriages supporting the print heads simultaneously print images onto media since the printer carriages are separated by a distance that is substantially to equal to at least one dimension of the image to be printed.
