Abstract: An oral drug delivery system for treatment of tuberculosis is described. The oral drug delivery system includes (e.g., a mixture or combination of): poly DL-lactide-co-glycolide nano particles having encapsulated an azole therein; poly DL-lactide-co-glycolide nano particles having moxifloxacin encapsulated therein; and poly DL-lactide-co-glycolide nano particles having RIF encapsulated therein.
Abstract: Onychomycosis is a fungal infection of the nail bed and is difficult to treat topically because penetration of the nail plate is difficult, and systemic antifungal treatments are prone to side effects and drug interactions. The present invention treats onychomycosis by applying an antifungal composition to the nail bed directly using a solid, semi-solid, or flowable carrier. The carrier can be in the form of a semi-solid into which the user digs and scrapes the nail, a solid carrier can be inserted directly under the nail in contact with the nail bed, or a flowable composition can be injected in contact with the nail bed.
Abstract: The invention relates to agents for temporarily shaping keratin fibers, said agents giving a very high degree of hold without impairing its flexibility and humidity resistance.
Abstract: Methods for making formulations of drugs and crystalline side chain polymers which formulations provide controlled and/or sustained release drug formulations.

Abstract: The present invention relates to a method for producing polymeric microspheres loaded with drugs and polymeric microspheres loaded with drugs produced thereby, specifically a method for producing polymeric microspheres loaded with drugs, the method comprising the steps of a) adding a dispersion phase containing a high molecular compound, a drug, and a water-insoluble organic solvent to a dispersion solvent to produce an O/W (oil-in-water) type or O/O (oil-in-oil) type emulsion, or adding a W/O (water-in-oil) type emulsion, which is prepared by emulsifying an aqueous solution, in which a drug is dissolved, in a water-insoluble organic solvent, in which the high molecular compound is dissolved, to the dispersion solvent to produce a W/O/W (water-in-oil-in-water) type emulsion; and b) adding an ammonia solution to the emulsion produced in step a) to convert the water-insoluble organic solvent into water-soluble solvents, and polymeric microspheres loaded with drugs produced thereby.

Abstract: A gel composition for removal of unwanted human hair from human skin that is comprised of a mixture of a majority portion of sugar and minor portions of lemon juice and water. The portions of sugar and lemon juice are initially heated to an appropriate temperature over a sufficient duration at which time the minor portion of water is added to the mixture. After adding water to the first mixture, the second mixture with water is heated until a composition of gel-like consistency has been produced. The composition is applied by hand or utensil to a part of human skin with unwanted hair and then covered with an absorbent layer of cloth until the unwanted hair has been dissolved by the composition at which time the cloth is removed from the skin with the composition absorbed therein and unwanted hair attached thereon.
Abstract: Provided herein are methods of using mannan oligosaccharides, to treat, palliate, relieve, prevent and/or eliminate urinary tract infections of humans. A mixture of oligosaccharides derived from yeast cell walls is shown to reduce, eliminate and prevent the symptoms of UTI in patients.
Abstract: The present invention provides an integral source material, the integral source material has at least one nuclide that is an integral source material having at least one nuclide that is activatable by exposure to radiation, the nuclide is a chemically bound constituent of a polymer of the integral source material, wherein the integral source material is configured before activation to provide a device.
Abstract: The present invention is directed to compounds which contain substituted naphthyridines which inhibit the activity of Akt, a serine/threonine protein kinase. The invention is further directed to chemotherapeutic compositions containing the compounds of this invention and methods for treating cancer comprising administration of the compounds of the invention. These substituted naphthyridines have unexpected advantageous properties when compared to other naphthyridines reported in PCT publication WO2003/086394, such unexpected advantageous properties may include increased cellular potency/solubility, greater selectivity, enhanced pharmacokinetic properties, lack of off target activity and so on.

Abstract: The present invention relates to a water soluble chitosan nanoparticle (WSC-NP) for delivering an anticancer agent and a preparing method thereof, more precisely, a water soluble chitosan nanoparticle for delivering an anticancer agent which has function of targeting on a wanted area by introducing a functional group in the location of highly reactive amine group and becomes an excellent gene carrier with the use of water soluble chitosan since the water soluble chitosan itself can combined with DNA having a negative electric charge(?) owing to the very strong positive electric charge(+) of its amine group, and a preparing method thereof. Therefore, a water-soluble chitosan nanoparticle for delivering an anticancer agent of the present invention can effectively envelope paclitaxel by introducing hydrophilic and hydrophobic groups in the position of highly reactive amine group of the water-soluble chitosan.
