Abstract: A magnetic field sensor, including an insulating substrate and a conductive thin film deposited on the substrate. The thin film consists of a material having an extraordinary Hall coefficient, the thin film also has a resistivity and a film thickness no greater than a threshold thickness at which the resistivity is substantially equal to 150% of a bulk resistivity of the material. The sensor also includes conductors coupled to the thin film for injecting a current into the film and measuring a voltage generated across the thin film responsive to the injected current. Devices having other types of thin films, including homogeneous and non-homogeneous films, the films having enhanced extraordinary Hall coefficients, are also provided.

Abstract: Binding of two members of a binding couple reveal epitopes which art revealed only after binding and antibodies directed against these epitopes bind to the bound couple at a significantly higher affinity than their binding affinity to either of the two members themselves when not bound to one another. The novel epitope and the antibodies of the invention have various therapeutic and diagnostic applications such as treatment and immunization against viral diseases.

Abstract: Binding of two members of a binding couple reveals epitopes which are revealed only after binding and the monoclonal antibody secreted from the hybridoma cell line CG-10 directed against these epitopes bind to the bound couple at a significantly higher affinity than their binding affinity to either of the two members themselves when not bound to one another.

Abstract: A method for diagnosing malignancy in a tumor. A waveform representative of pulsatile blood flow in the tumor is measured, and the post-systolic portion of the wave form is fit with a mathematical function such as an exponential decay curve. A decay constant greater than about 48 pixels is diagnostic of malignancy.

Abstract: Use of a compound selected from the group consisting of pentoxifylline, propentofylline and torbafylline for topical treatment of psoriasis or atopic dermatitis and pharmaceutical compositions comprising them.

Abstract: The invention relates to compositions which induce in humans regeneration of the corneal endothelium. The compositions of the invention are of value in regenerating the corneal endothelium in humans, which is frequently damaged in the course of eye surgery and injuries. Such regeneration is very important to ensure the full functionality of the eye. The compositions of the invention comprise as active ingredient an adequate quantity of fibroblast growth factor (FGF) in a suitable physiologically acceptable vehicle. A preferred embodiment of the invention relates to a composition containing a certain quantity of hyaluronic acid and any other viscoelastic agent.

Abstract: Enzymes are stabilized by encagement in a double layer having a polyaldeh base coat linked to the amino groups of the enzyme, and an outer polymer coat crosslinked therewith. The outer coat is made of a polymer which in the unlinked state has free amino and/or acyl hydrazide groups.Optionally the stabilized enzyme is immobilized within a matrix.Processes for the preparation of the encaged and optionally immobilized enzymes are described.

Abstract: The invention relates to an electrochemical cell which is safe even under adverse conditions and abuse. The cells comprise an alkaline metal anode, a current collector and an inorganic oxyhalide liquid cathode which contains an alkaline earth metal salt in a suitable solvent, such as thionyl chloride. The cell may contain sulfur dioxide dissolved in the solvent. Suitable salts are alkaline earth metal aluminum chlorides.

Abstract: A channel electron multiplier is described having a tubular wall coated w a secondary-electron emitting material and including an electric field for accelerating the electrons, the electric field comprising a plurality of low-resistive conductive rings each alternating with a high-resistive insulating ring. The thickness of the low-resistive rings is many times larger than that of the high-resistive rings, being in the order of tens of microns for the low-resistive rings and at least one order of magnitude lower for the high-resistive rings; and the diameter of the channel tubular walls is also many times larger than the thickness of the high-resistive rings. Both single-channel and multiple-channel electron multipliers are described. A very important advantage, particularly in making multiple-channel multipliers, is the simplicity of the procedure that may be used in constructing such multipliers. Other operational advantages are described.
