Abstract: Abstract For use in ophthalmic surgery, the surgeon has available a supply of "spare parts" which are artifi-cial members, possibly simulating different components of the eye, that are suited, depending on their struc-tural forms and shapes, for surgical implantation in the eye as and/or in connection with repair and/or re-enforcement and/or replacement structures for damaged or diseased eye components.  The members basically are made of cohesive sheet materials of biocompatible sub-stances such as cross-linked hyaluronic acid, PMMA, or other equivalents thereof.  Certain of such "spare parts" are particularly well suited for dealing with the problem of the torn posterior capsule when encoun-tered during an extracapsular cataract extraction.

Title: Apparatus for dilating a body cavity
Inventor: WATERS GERARD A
IPC: A61M29/00
Filed: 1989-04-11
Granted: 1993-05-11
Abstract: ABSTRACT            The invention provides an apparatus for dilating a body cavity comprising an expandable member having a normal position and a dilated position.  In the normal position, the member defines a narrow generally elongate shape for insertion in a body cavity.  A means is provided to expand the member to its dilated position in which the member forms a hollow generally open ended elongate shape having a substantially continuous sidewall to dilate the body cavity. In one form the expandable member comprises a sheet of material capable of being rolled into the normal position, and the means to expand the member comprises an inherent resilience of the sheet of material causing it to be naturally urged into a partially unrolled dilated position.

Abstract: Specific binding assays are disclosed which utilize a sensitizer as a label.  Such sensitizers include any moiety which, when stimulated by "excitation" wlth radiation of one or more wavelengths or other chemical or physical stimulus (e.g., electron transfer, eLectrolysis, electroluminescence or energy transfer), will achieve an excited state which (a) upon interaction with molecular oxygen will produce singlet molecular oxygen, or (b) upon interaction with a leucodye will assume a reduced form which can then be returned to its original unexcited state by interaction with molecular oxygen resulting in the production of hydrogen peroxide.  Either interaction with the excited sensitizer will, with the addition of other reagents, produce a detectable signal.

Abstract: METHOD OF PRODUCING MIXED METAL OXIDE MATERIAL, AND OF PRODUCING A BODY COMPRISING THE MATERIAL Abstract A novel method of producing mixed metal oxide powder (e.g., ferrite powder, or high temperature superconductor powder such as YBa2Cu3Ox powder) is disclosed. The method comprises forming an intimate mixture of appropriate metalsalts (e.g.., nitrates and acetates), at least one of which is an oxidizing agent with respect to at least one of the others, and heating the mixture to a reaction temperature such that an exothermic redox reaction occurs. Appropriate choice of oxidizing and reducing agents permits control of heat of reaction and reaction temperature. The product of the reaction typically is a precursor of the desired mixed oxide, theprecursor typically consisting essentially of the metal constituents of the mixed oxide and oxygen. Heat treatment in an O2-containing atmosphere transforms the precursor into the desired mixed oxide powder. The thus produced powder can thenbe used in conventional fashion, e g., to produce bodies therefrom by pressing and/or sintering.

Abstract: A nucleic acid probe, wherein the label is a catalytically active enzyme, is provided.  The nucleic acid of the probe is a DNA or a RNA and comprises a segment of at least 20 nucleotides in the sequence complementary to that of the target segment of the probe.  In the probe, the nucleic acid and enzyme are covalently joined by a linker, which is bonded, at one end, to the 5'-carbon of the 5'-nucleotide of the nucleic acid and, at the other end, to the enzyme and which comprises an hydrazone or hydrazide group.  Also provided is a nucleic acid, which is an intermediate for making a probe according to the invention and which is derivatized, at the 5'-carbon of the 5'-nucleotide, with a moiety with a free hydrazino group.  Further provided are methods of making a nucleic acid probe of the invention.  In one such method, a nucleic acid of the invention is reacted with an enzyme, which is derivatized to have an aldehyde group.  In another such method, a probe of the invention, with an hydrazone in the linker joining the nucleic acid and enzyme, is reduced with cyanoborohydride; such reduction changes the hydrazone to an hydrazide but otherwise does not substantially affect the probe.  Further, a method is provided for detecting a nucleic acid analyte by carrying out a nucleic acid probe hybridization assay with a probe according to the invention for the analyte.  Finally, the invention provides the compound 4-N'-benzylamidobenzaldehyde and nucleic acid probes labeled with 2,4-dinitrophenyl or 4-N'-benzylamidophenyl through a linker which comprises an hydrazone or hydrazide group.
