  • Publication number: 20130152271
    Abstract: A nursing cape covers a mother's upper torso and does not expose the feeding child or the mother's breast to public view while the child is breastfeeding. The nursing cape includes a front panel, a back panel, a neck opening formed between the front panel and the back panel, and a collar attached around a perimeter of the neck opening. A first fastening system and a second fastening system are secured to the collar. The first fastening system and the second fastening system are coupled together to adjust the size of the neck opening. A first hand opening is located proximate to the first side seam of the front panel. A second hand opening is located proximate to the second side seam of the front panel. The first hand opening and the second hand opening allow a user to slip the hands through them when wearing the nursing cape.

  • Publication number: 20080152632
    Abstract: This invention provides a system for rapid determination of pharmacologic effects on target tissue types in cell populations cultured in vitro. The cells contain a promoter-reporter construct that reflects a toxicologic or metabolic change caused by the agent being screened. The promoter is taken from a gene known to be up- or down-regulated according to the metabolic state of the cell, and linked to a reporter gene that provides an external signal for monitoring promoter activity. The promoter-reporter cells may be produced by placing these genetic alterations into a line of human embryonic stem cells, bulking up the cells to any extent desired, and then differentiating the cells into the desired tissue type. This disclosure explains some of the powerful features of the promoter-reporter cells of this invention, and shows various ways the skilled reader can use the invention for pharmaceutical development and testing, or to monitor graft survival.

  • Publication number: 20070217999
    Abstract: The present invention provides a reporter system comprising a reporter gene encoding a reporter protein that is secretable from cells in which it produced or expressed either in vitro or in vivo and excretable in a body fluid from whole animals comprising such systems. The reporter system is useful for the detection of gene activation events or biochemical changes related to, or that occur, as a result of altered metabolic or disease status or toxicological stress in toxicological screening.

  • Publication number: 20060105323
    Abstract: A system for the detection of gene activation events is provided which comprises a nucleic acid construct encoding a protein of the lipocalin protein family and a peptide tag in which the expression of the construct in a cell or in the cells of a transgenic animal demonstrates the activation of a gene or genes of interest, in which the protein expressed is secreted from the cell and in which detection of the peptide tag indicates expression of the construct.

  • Patent number: 5477038
    Abstract: A process which provides electronic access to pre-paid funds for cash or payment for goods and services. A card is issued to a customer with a value selectable by the customer. The card has a magnetic stripe with an encoded card number including a bank identification number (BIN) and an account number. The central card processor establishes a zero balance database including the card numbers, but with blank fields for the customer data and the value of the account. When a customer purchases a card, the sales agent transmits to the central database computer which fills in the blanks in the database, activating the account, and transmits an acknowledgement signal back to the sales agent. The customer can immediately use the card in ATM or other remote terminals to acquire cash or purchase goods and services. The customer inputs a PIN number which is provided with the card, or a customer selected alternative PIN number.
