    摘要: Provided are compositions and methods for therapy of macular degeneration including dry age-related macular degeneration (dAMD), juvenile macular degenerations (JMDs) where toxic retinoids are known to accumulate as part of the pathogenesis, such as Stargardt disease, and Best disease, and neovascular wet age-related macular degeneration. The method entails administering to an individual in need of therapy for macular degeneration a first polynucleotide that can facilitate a reduction in the amount of rod opsin (RHO) mRNA in the individual; or a second polynucleotide that can facilitate a reduction in the amount of RPE65 mRNA in the individual; or a combination thereof. The polynucleotides of the invention are hammerhead ribozymes or shRNAs. The polynucleotides target a sequence in RHO mRNA or RPE65 mRNA and facilitate reduction in the target mRNA via ribozymatic cleavage of the target, or by hybridization to the target, which leads to RNAi mediated degradation of the target mRNA.

    摘要: The present invention relates to the reaction of phosphate rock with nitric acid and urea to produce nitrogen-phosphorus containing slurries, which slurries may be granulated and dried to produce solid N-P fertilizer products with agronomically advantageous low pHs (1.1-4.0). Products with optimum physical and chemical properties were discovered by investigating the characteristics of each individual material as a function of the nitric acid acidulation ratio (mole ratio HNO.sub.3 :CaO) and the mole ratio urea:CaO present in each product. Acidulation ratios ranged from 1.2 to 2.1 while ratios urea:CaO ranged from 1.6 to 4.0. Selected products with optimum physicochemical properties are tabulated below:______________________________________ Acidulation Ratio Ratio Melting HNO.sub.3 :CaO, M/M Urea:CaO, M/M Grade Pt, .degree.C. ______________________________________ 1.2 2.2 23.8--11.7--0 137-139 1.4 2.4 25.0--11.0--0 136 1.6 2.8 25.9--9.9--0 133-137 1.8 3.0 26.4--9.2--0 134-135 2.0 3.3 27.2--8.7--0 130 2.1 3.2 36.6--8.8--0 125-130 ______________________________________ Acidulation P.sub.2 O.sub.5 Solubility, Critical Rela- Ratio % pH of 1% tive Humidity HNO.sub.3 :CaO, M/M Water Citrate solution at 25.degree.

    摘要: A process for producing high-analysis dicalcium phosphate containing phosphatic fertilizers and by-product calcium nitrate. It comprises reacting phosphate rock with nitric acid, followed by pyrolysis of the resulting acidulate to effect liberation of approximately one-half of the initially consumed nitric acid. Recycling of this liberated nitric acid allows production of available phosphate with approximately one-half the acid equivalents normally consumed during sulfuric acid processing. The calcium nitrate in the resulting pyrolyzate is separated from the phosphatic constituent by dissolution in water followed by filtration. Depending upon the initial HNO.sub.3 :CaO acidulation ratio, the available phosphate content of the resulting solid phosphatic fertilizers is high enough (48% P.sub.2 O.sub.5) to allow their use either for bulk blending with nitrogen and potash salts to produce complete grade fertilizers or for direct application as a phosphate nutrient. The resulting calcium nitrate stream may be processed to produce a variety of solid or fluid nitrogen fertilizer products. No "throw away" by-products (other than possibly siliceous gangue) are produced.

    摘要: A process for oxidizing aqueous elemental phosphorus containing residues (sludges) to produce orthophosphate containing slurries suitable for subsequent reaction with ammonia to produce nitrogen- and phosphorus-containing fertilizer products. It comprises reacting aqueous elemental phosphorus containing residues with certain special mixtures of concentrated nitric acid and sulfuric acid to effect the conversion of the elemental phosphorus content of the residues into mostly orthophosphoric acid and very little orthophosphorous acid with the relative ratios of orthophosphoric acid to orthophosphorous acid produced being dependent upon the weight ratio H.sub.2 SO.sub.4 :HNO.sub.3 employed in the processing. The reaction is conducted at the boiling point of the resulting aqueous reaction medium. Prior to the conversion to fertilizer products, the aqueous reaction product intermediate may be subjected to a solids separation step to remove insoluble salts of certain environmentally undesirable metals, such as, Pb, Cd, Ba, and Cr which are derived from phosphate rock via the dust component of phosphorus sludge.
