A method for monitoring a patient for rejection reactions to an implanted organ is provided with an implantable telemetry measuring unit with electrodes that can be implanted in the organ. An electric current is passed through the body tissue via two current electrodes. The impedance of the body tissue through which this current is flowing is determined with two measuring electrodes. Each of the m...

A method and a device for detecting the thickness of a layer of fat is described, in which the layer of fat is illuminated at different sites. In the process, the light intensity emanating from the layer of fat is measured to determine the illumination at the various sites, and the thickness of the layer of fat is inferred from the relationship of the various intensities.

The illumination unit (4) is mounted in the inside of the frame (1), so that it is covered by a screen, so that the light does not shine directly in to the eyes. An indicating unit (7) of a miniaturised electro-nystagmography unit (5) is integrated in the frame (5). The electro-nystagmography unit (4) is fitted in the frame (1), between and above the eyes, and above the bridge of the nose. The ele...

A coated article and method of forming the same. The article is composed of a carbon body having a thermochemically deposited coating which renders the body resistant to oxidation at high temperatures. The coating is formed of a silicon alloy having a non-columnar grain distribution with substantially equiaxial grains of an average diameter of less than one micron. The amount of silicon in the coa...

PURPOSE:To properly erase the coordinate data of a destination from a memory even after the arrival of a vehicle at the destination. CONSTITUTION:When a distance from a current position up to a destination is less than a prescribed value at the time of starting the engine of the vehicle, destination coordinate data stored in a memory are erased. Since the destination coordinate data are not erased...

Sanitary napkins are disclosed which include at least one flap (10) having a portion that may be expanded longitudinally for permitting the flap (10) to expand when folded over a side of an undergarment (25). This enables the flap (10) to fold outwardly to the back of the undergarment (25) and conform to the contour along the curved line of the crotch. Thus, an improved sanitary product is provide...

Assay for detecting the presence or absence of a particular genetic sequence in a nucleic acid strand. Double stranded sample nucleic acid is reacted with a restriction endonuclease whose activity depends on the presence or absence of the particular base sequence to be detected at the restriction site. The DNA is denatured and reacted with an immobilized nucleic acid probe and a labeled nucleic ac...

The sound absorbing material has a polyognal cross-section (2) incorporating a porous structure. The material is also anisotropic in that it has a modulus of elasticity E in one direction which is less than the modulus of elasticity in at least one other direction. The material has a soundwave impedance characteristic in one direction which is of the same order of magnitude as the sound wave imped...

The present invention relates to methods which utilize anti-idiotypic antibodies, or fragments thereof, for tumor immunotherapy or immunoprophylaxis. Monoclonal anti-idiotypic antibodies which recognize an idiotype present on a second antibody or on a T lymphocyte or on an immune suppressor factor which is directed against a defined tumor antigen, can be used for immunization against a tumor, for ...
