20130164424 | PRODUCTION OF LOW SODIUM SALT WITH BALANCED MINERAL CONTENT - A process is provided for preparing a salt product with reduced sodium content including the step of providing a concentrated brine, which is typically seawater, to which has been added potassium chloride. The mixture is transferred to a crystalliser unit where at least a portion of the mix is transferred to the crystalliser through a washing column. Liquid is evaporated from the crystalliser such that crystals form, crystals are passed from the crystalliser through said washing column to a separating unit such that in the passing through the washing column the crystals are rinsed with the brine portion being transferred as a counter current through the column. The inventive process is characterised by recycling of the brine from which the salt crystallises, thus all main ingredients of the mixed input brine reach a steady equilibrium concentration in the mother liquor in the crystalliser. These will then precipitate as crystals, as more of the respective substances gets added to the mother liquor through inflow of mixed input brine. None of the liquor is purged out of the system as in conventional salt crystallisers. All the components in the feed are substantially contained in the product from the crystalliser either as crystalline material or soluble ingredients. | 06-27-2013 |

20090105456 | Porous keratin construct and method of making the same - The invention relates to a porous keratin construct material comprising keratin protein for use in wound healing applications. The porous keratin construct is capable of bio-absorbing into a wound to promote wound healing. The rate at which the construct bio-absorbs into the wound may be controlled altered by controlling the degree of disulfide cross-linking between the keratin proteins in the porous keratin construct. The invention is also related to a method of making the porous keratin construct. | 04-23-2009 |

20130196862 | Informatics Enhanced Analysis of Fetal Samples Subject to Maternal Contamination - The invention provides methods for chromosome copy number calling on genetic samples, such as fetal samples subject to contamination from maternal DNA. The present disclosure provides methods for determining the ploidy status of a chromosome in a fetus (such as a gestating fetus or a POC sample) from genotypic data measured from a mixed sample of DNA comprising DNA from both the mother of the fetus and from the fetus, and optionally from genotypic data from the mother and father. In some embodiments, the ploidy state is determined by using a joint distribution model to create a plurality of expected allele distributions for different possible fetal ploidy states given the parental genotypic data, and comparing the expected allelic distributions to the pattern of measured allelic distributions measured in the mixed sample, and choosing the ploidy state whose expected allelic distribution pattern most closely matches the observed allelic distribution pattern. The mixed sample of DNA may be preferentially enriched at a plurality of polymorphic loci in a way that minimizes the allelic bias, for example using massively multiplexed targeted PCR. | 08-01-2013 |
