  • Patent number: 6977246
    Abstract: The present invention relates to certain novel dinucleotides and formulations thereof which are highly selective agonists of the P2Y2 and/or P2Y4 purinergic receptor. They are useful in the treatment of chronic obstructive pulmonary diseases such as chronic bronchitis, PCD, cystic fibrosis, as well as prevention of pneumonia due to immobility. Furthermore, because of their general ability to clear retained mucus secretions and stimulate ciliary beat frequency, the compounds of the present invention are also useful in the treatment of sinusitis, otitis media and nasolacrimal duct obstruction. They are also useful for treatment of dry eye disease and retinal detachment as well as facilitating sputum induction and expectoration.

  • Patent number: 6919446
    Abstract: Disclosed are a method for the reduction of an oligosaccharide mixture and an oligosaccharide mixture prepared thereby. In accordance with the disclosed invention, a mixture of oligosaccharides having a given DP profile is reduced to a DE of essentially zero by catalytically hydrogenating the mixture under reaction conditions sufficient to preserve the DP profile of the mixture, which reaction conditions typically include a reaction temperature ranging from about 50° C. to about 150° C. and a reaction pressure of at least about 1500 psi. Surprisingly, when the mixture is a malto-oligosaccharide mixture, the reduced mixture will have a superior color-fastness and thermal stability as compared to a similar unreduced mixture of malto-oligosaccharides, and also low reactivity towards nitrogen-containing species.

  • Patent number: 6893832
    Abstract: Disclosed is a method for quantifying cholesterol in HDL, which does not require complex fragmentation and separation operations, and by which the HDL cholesterol in test samples containing HDL and other lipoproteins such as low density lipoprotein (LDL), very low density lipoprotein (VLDL) and chylomicron (CM) may be quantified selectively, simply and accurately. The method for quantifying cholesterol in high density lipoprotein comprises a first step of erasing cholesterol in lipoproteins other than high density lipoprotein in a test sample, and a second step of adding a surfactant which specifically acts on high density lipoprotein to the product of the first step and enzymatically quantifying cholesterol in high density lipoprotein.

  • Patent number: 6869938
    Abstract: The present invention relates to improved methods for making and using bioadhesive, bioresorbable, anti-adhesion compositions made of intermacromolecular complexes of carboxyl-containing polysaccharides, polyethers, polyacids, polyalkylene oxides, multivalent cations and/or polycations. The polymers are associated with each other, and are then either dried into membranes or sponges, or are used as fluids or microspheres. Bioresorbable, bioadhesive, anti-adhesion compositions are useful in surgery to prevent the formation and reformation of post-surgical adhesions. The compositions are designed to breakdown in-vivo, and thus be removed from the body. Membranes are inserted during surgery either dry or optionally after conditioning in aqueous solutions.
