  • Publication number: 20130101654
    Abstract: A mechanical insecticide is made by mixing water with at least one type of silane to make a silane solution which is then mixed with diatomaceous earth until there is substantial deposition of the silane material on the diatomaceous earth material, to make a silanized diatomaceous earth. The silanized diatomaceous earth can be diluted with water and applied to vertical and overhead surfaces using a sprayer, for the control of insects. The silanized diatomaceous earth can also be dried into a powder for broadcast application, or mixed as a paste for brush/roller/caulk application.

  • Patent number: 8419803
    Abstract: Methods and compositions for producing flowable compositions, e.g. pastes, that set into calcium phosphate products are provided. In the subject methods, dry reactants that include a calcium source and a phosphate source are combined with a setting fluid to produce the flowable composition. A feature of the subject methods is that the dry reactants include a particulate calcium and/or phosphate reactant having a mean particle size of less than about 8 ?m and narrow size distribution. Also provided are the compositions themselves as well as kits for use in practicing the subject methods. The subject methods and compositions produced thereby find use in a variety of applications, including the repair of hard tissue defects, e.g., bone defects.

  • Patent number: 8388984
    Abstract: Compositions which deliver adsorbents, alone or in combination with active drug “degrading molecules,” in a site-specific manner to the intestine, and which eliminate or at least lower the concentration of residual unwanted material within the intestine, and methods of treatment using the compositions, are disclosed. The compositions are ideally designed to specifically release the adsorbents in a programmed manner at a specific site of the intestinal tract. Programmed delivery prevents adsorbents from interfering with the normal absorption process of a given molecule after oral absorption, until it reaches the lower part of the small intestine. The compositions can be used to adsorb, and therefore remove, any residual drug, metabolite thereof, or bacterial toxin after oral or parenteral administration which would otherwise cause adverse effects in the lower intestine and/or colon.
