  • Patent number: 8524739
    Abstract: This disclosure provides a new class of compounds referred to as “reversed chloroquines” (RCQs), which are highly effective against CQR and CQS malaria parasites. RCQs are hybrid molecules, which include an antimalarial quinoline analog (such as chloroquine) moiety and a CQR reversal moiety. Exemplary RCQ chemical structures are provided. Also provided are pharmaceutical compositions including the disclosed RCQ compounds, and methods of using such compounds and compositions for the treatment of malaria and inhibition of CQR or CQS Plasmodium sp. (such as P. falciparum).

  • Publication number: 20120118764
    Abstract: A closure 40 for a container body includes a liner 46 which incorporates a hydrogen generating device comprising a hydride which generates hydrogen on contact with moisture. The liner may be an interference fit within the body 42. The liner 46 and other liners described may include control means for controlling passage of moisture to the hydrogen generating means and/or sealing means for sealing the closure to a container. In use, with the closure secured to a container, water vapour passes into liner 46 and contacts the hydride which generates hydrogen. A reaction between hydrogen and oxygen which has passed into the container takes place, catalysed by a catalyst, and water is produced. Thus, oxygen is scavenged.

  • Publication number: 20120114529
    Abstract: A closure (40) includes a body (42) with a screw threaded portion (44) for engaging the closure with a container, for example a bottle. Inwards of portion (44) is a liner (46) comprising a hydrogen generating device, wherein the liner includes one layer (48) which incorporates a hydride dispersed in a polymeric matrix and, on opposite sides of layer (48) are arranged PET layers (50, 52). Layer (50) is arranged to act as a control layer to control the rate of passage of water vapour from the beverage in the container to the hydride containing layer (48) and thereby control generation of hydrogen by the hydrogen generating device. In use, water vapour passes through layer (50) and contacts the hydride associated with layer (48) which results in production of molecular hydrogen which combines with oxygen which may have entered a container with which the closure (40) is associated.

  • Publication number: 20100028499
    Abstract: A container (22) includes a shell (24) made from a polymer, for example PET, and incorporating a catalyst, for example a palladium catalyst. A closure (40) incorporates a plug which includes a source of hydrogen, for example a hydride. In use, with container (22) including a beverage and closure (40) in position, the headspace in the container will be saturated with water vapor. This vapor contacts the hydride associated with plug (42) and as a result the hydride produces molecular hydrogen which migrates into the polymer matrix of shell (24) and combines with oxygen which may have entered the container through its permeable walls. A reaction between the hydrogen and oxygen takes place, catalysed by the catalyst, and water is produced. Thus, oxygen which may ingress the container is scavenged and the contents of the container are protected from oxidation.

  • Publication number: 20070050064
    Abstract: A method for fabricating a component using a tool includes determining an actual property of a region of the component, comparing the actual property of the region of the component with an expected property of the region to determine a difference between the actual property and the expected property, and updating a path of the tool that is electronically stored in a memory and executable by a processor for fabricating the component based on the difference between the actual property and the expected property of the region.

  • Publication number: 20050182670
    Abstract: A method for arranging a life insurance transaction while managing risk exposure associated with the transaction is disclosed. In one embodiment, the method includes coordinating the initiation of an insurance policy that relates to the life of a person. Execution of a loan on behalf of an owner of the policy for the payment of premiums due on the policy is also coordinated with a lending entity. The posting of collateral for the loan by a third party is coordinated, thereby removing risk exposure from the lending entity, the policy owner, and/or the insured.
