Apparatus and method for quantifying the biological components of a biological system having at least two different refractive indices through detection of wave front distortions. The biological component fractions are determined based on information gathered on their respective indices when exposed to particular wavelengths of light.

There is disclosed antibody molecules containing at least one CDR derived from a mouse monoclonal antibody having specificity for human TNF.alpha.. There is also disclosed a CDR grafted antibody wherein at least one of the CDRs is a hybrid CDR. Further disclosed are DNA sequences encoding the chains of the antibody molecules, vectors, transformed host cells and uses of the antibody molecules in the treatment of diseases mediated by TNF.alpha..

A biological electrode includes an electrode element having electroconductivity with respect to a living body, the biological electrode used by disposing said electrode element at a predetermined position, and the electrode element being made of biodegradable material.

Methods for exterminating pests using compositions comprising at least one protease enzyme. A detergent component may also be utilized in such compositions.

Airborne particles are impacted on a collection surface, analyzed, and then the collection surface is regenerated. Thus, the same collection surface can be used in numerous cycles. The analysis can be focused on one or more properties of interest, such as the concentration of airborne biologicals. Sensors based on regenerative collection surfaces may be incorporated in many networks for applications such as building automation.

There is disclosed antibody molecules containing at least one CDR derived from a mouse monoclonal antibody having specificity for human CD22. There is also disclosed a CDR grafted antibody wherein at least one of the CDRs is a modified CDR. Further disclosed are DNA sequences encoding the chains of the antibody molecules, vectors, transformed host cells and uses of the antibody molecules in the treatment of diseases mediated by cells expressing CD22.

Methods for exterminating pests using compositions comprising at least one protease enzyme. A detergent component may also be utilized in such compositions.

A spray-type cryogenic probe including a dual stream, cryogenic liquifier for converting stored gas into an ultracold liquid which is ejected from the probe in a fine, controlled stream to freeze tissue.

A laboratory lamp is provided for supplying a constant source of daylight-bright, soft, evenly diffused light for the examination of test plates which are translucent or transparent. A generally cylindrical housing has a recess in the center of its top wall for holding a plate to be examined. Near the bottom of the housing is a white light source providing light emitted evenly around a circumference substantially concentric with the cylindrical housing. A light baffle is supported in the housing...

An apparatus is disclosed comprising an electrode for detection of biopotentials, and a high-input impedance, low-noise amplifier packaged with and in direct contact with the electrode, the input terminal of the first active device of the amplifier being epoxy bonded to the electrode. The amplifier is designed with thick film resistors, and without any capacitors, thus minimizing noise generation in the amplifier.
