Protein stabilized pharmacologically active agents, methods for the preparation thereof and methods for the use thereof

In accordance with the present invention, there are provided compositions and methods useful for the in vivo delivery of substantially water insoluble pharmacologically active agents (such as the anticancer drug paclitaxel) in which the pharmacologically active agent is delivered in the form of suspended particles coated with protein (which acts as a stabilizing agent). In particular, protein and pharmacologically active agent in a biocompatible dispersing medium are subjected to high shear, in the absence of any conventional surfactants, and also in the absence of any polymeric core material for the particles. The procedure yields particles with a diameter of less than about 1 micron. The use of specific composition and preparation conditions (e.g., addition of a polar solvent to the organic phase), and careful election of the proper organic phase and phase fraction, enables the reproducible production of unusually small nanoparticles of less than 200 nm diameter, which can be sterile-filtered. The particulate system produced according to the invention can be converted into a redispersible dry powder comprising nanoparticles of water-insoluble drug coated with a protein, and free protein to which molecules of the pharmacological agent are bound. This results in a unique delivery system, in which part of the pharmacologically active agent is readily bioavailable (in the form of molecules bound to the protein), and part of the agent is present within particles without any polymeric matrix therein.

Precursors for CVD silicon carbo-nitride films

Classes of liquid aminosilanes have been found which allow for the production of silicon carbo-nitride films of the general formula SixCyNz. These aminosilanes, in contrast, to some of the precursors employed heretofore, are liquid at room temperature and pressure allowing for convenient handling. In addition, the invention relates to a process for producing such films. The classes of compounds are generally represented by the formulas: and mixtures thereof, wherein R and R1 in the formulas represent aliphatic groups typically having from 2 to about 10 carbon atoms, e.g., alkyl, cycloalkyl with R and R1 in formula A also being combinable into a cyclic group, and R2 representing a single bond, (CH2)n, a ring, or SiH2.

Endopelvic fascia treatment for incontinence

Methods, devices, and systems for treating the support structures of the body, particularly for incontinence, take advantage of two mechanisms to enhance the support provided by the fascia, ligaments and tendons: first, the invention increases a modulus of elasticity of these tissues, and particularly of the fascial tissues. The increase in modulus can be effected by directing sufficient energy to the fascial tissue so as to promote the formation of scar tissue. The second mechanism attaches tissue planes together, often by directing energy to an interface between adjacent fascial tissues.

The present invention provides systems and methods for selectively applying electrical energy to a target location within the head and neck of a patient's body, particularly including tissue in the ear, nose and throat. In one aspect, a method is provided for reducing the volume of enlarge swollen tissue in the patient's nose, such as swollen nasal tissue, mucus membranes, turbinates, polyps, neoplasms, cartilage (e.g., the nasal septum) or the like. In particular, the turbinates are treated by positioning one or more electrode terminal(s) adjacent to the turbinates, and delivering electrically conductive fluid, such as isotonic saline, to the nasal cavity to substantially surround the electrode terminal(s) with the fluid. High frequency voltage is applied between the electrode terminal(s) and one or more return electrode(s) to remove a small tissue segment, channel or hole from the region near or in the turbinates to shrink the turbinates and prevent swelling, due to the formation of scar tissue as the wound heals. The high frequency voltage may be selected to effect a small amount of thermal damage to the walls of the channel or hole to facilitate the formation of scar tissue without extending this thermal damage beyond the immediate region of the target site.

Bag for use in the intravascular treatment of saccular aneurysms

A bag for use in the intravascular treatment of saccular aneurysms and a method of forming the bag are disclosed. The bag is formed from a plurality of flexible, resilient filamentary members braided into a tubular sleeve and biased into a first shape having an expanded first diameter sized to substantially fill the aneurysm. The bag is resiliently deformable into a second shape having a diameter smaller than the first and sized to slidingly interfit within the lumen of a catheter. An opening is provided in the bag to receive a clotting medium, such as a platinum wire, on which blood clots can be induced to form by mechanical or electrolytic means. The opening is urged to a closed position by resiliently biasing the filamentary members. In use the, bag is inserted into a saccular aneurysm via the catheter and expands to its first diameter upon release therefrom. Interstices between the interbraided filamentary members provide pores allowing blood from the aneurysm to enter the bag when the bag is positioned within the aneurysm. The clotting medium wire is packed into the bag, blood clots on the wire and occludes the aneurysm, sealing it off from the blood stream and preventing rupture. The wire is released from the catheter and is contained within the bag in the aneurysm.

Natural input recognition tool

A recognition tool according to various examples of the invention intelligently recognizes natural input before it is passed to a destination or target application. More particularly, the recognition tool according to various examples of the invention provides better formatting for text recognized from natural input, based upon the context in which the text is being inserted into a target application. The recognition tool also provides various tools for correcting inaccurately recognized text. The recognition tool may allow a user to select only a part of an inaccurate text, and then identify alternate text candidates based upon the selected portion of the inaccurate text. Further, when the user selects text containing multiple words for correction, the recognition tool provides cross combinations of alternate text candidates for the user's selection. Still further, if the user replaces inaccurate text by submitting a new natural input object, the recognition tool ensures that the text recognized from the new natural input object is different from the inaccurate text been replaced. The recognition tool additionally affects the recognition experience after recognized text has been provided to the target application. The recognition tool provides the target application with the original natural input object for the recognized text, along with the alternate text candidates for that original natural input object. Thus, the target application can use the alternate text candidates to correct inaccurately recognized text. Further, a user can insert the original natural input object for recognized text within the target application.

Sequestration of carbon dioxide

A process for selectively removing carbon dioxide from a gaseous stream by converting the carbon dioxide to a solid, stable form is provided. In a sequestration process, carbon dioxide enriched air is passed through a gas diffusion membrane to transfer the carbon dioxide to a fluid medium. The carbon dioxide rich fluid is then passed through a matrix containing a catalyst specific for carbon dioxide, which accelerates the conversion of the carbon dioxide to carbonic acid. In the final step, a mineral ion is added to the reaction so that a precipitate of carbonate salt is formed. This solid mineral precipitate can be safely stored for extended periods of time, such as by burying the precipitate in the ground or depositing the precipitate into storage sites either on land or into a body of water. An apparatus for removing carbon dioxide from a gaseous stream is also provided.

Stent and process for producing the same

InactiveUS20060036311A1Risk of twistingRisk of tearingStentsButtonsThrombusPolymer
A stent comprising a tubular stent matrix of which diameter is extendable and a flexible polymer layer covering the stent matrix. The polymer layer is closely attached to and covers the entire surface of the stent matrix. Since the flexible polymer layer closely covers the entire surface of the stent matrix not only the outer periphery of the stent matrix, the stent has no problem of causing allergic to metal, stimulus of tissues due to metal, and rust development. Since the inner periphery of the stent is a flat and smooth surface covered by the polymer layer without convexes and concaves, the formation of thrombus can be inhibited well. There is no problem of drift between the polymer layer and the stent matrix, thereby maintaining the positional relationship between the stent matrix and the polymer layer before and after the expansion of the stent.
