  • Publication number: 20230227575
    Abstract: A therapeutic molecule (single chain-based antibody or ligand-based) optimized for expression and secretion from engineered T cells, which may be gamma delta (gd) T cells. When expressed from engineered gdT cells, the STAR will be secreted and mediate engagement between gdT cells and antigen/receptor on target cells. Binding mediates the formation of a cytolytic synapse between the gdT cell and the target cell leading to activation the gdT cells to release proteolytic enzymes that kill target cells.

  • Patent number: 7575918
    Abstract: The present invention relates to the discovery, identification and characterization of toxic agents which are lethal to pathogens and methods for targeting such toxic agents to a pathogen or pathogen infected cells in order to treat and/or eradicate the infection. In particular, the present invention relates to toxic agents which target bacteria at different stages of the bacterial life cycle, which are delivered alone or in combination to bacteria or bacteria-infected cells. The invention relates to toxic agents which are lethal to diseased cells and methods for targeting such toxic agents to a diseased cell in order to treat and/or eradicate the disease. The present invention relates to promoter elements which are pathogen-specific or tissue-specific and the use of such promoter elements to achieve pathogen-specific or tissue-specific expression of the toxic agent(s) and/or ribozyme(s) of the present invention.

  • Publication number: 20050232808
    Abstract: An exemplary oil burning lamp comprises a reservoir configured for storing a supply of oil, a base, a burner tube and a wick. The base is being sized and shaped to receive the reservoir. The burner tube is movably mounted to the reservoir between a retracted position and an extended position. The burner tube has a first end, an opposing second end and at least one opening. In the retracted position, the both ends are located within the reservoir. In the extended position, the first end is located within the reservoir, the second end is located outside the reservoir, and the opening is located such that fragranced components of oil stored in the reservoir can be entrained by air and emanated from the base. The wick is mounted to the burner tube, extends into the reservoir, and extends outwardly from the second end of the burner tube.

  • Patent number: 4786747
    Abstract: Benzamides of the formula (I): ##STR1## in which Ar is optionally substituted aryl; X is O, S or NH and R is optionally substituted alkyl or alkenyl when X is O or S, or is optionally substituted alkanoyl when X is NH, are prepared by(a) reacting a compound of the formula (II):ArCONHCH.sub.2 CN (II)with a brominating agent in a solvent which is substantially chemically inert to the reactants and in which compound (II) is soluble, to form a compound of the formula (III): ##STR2## and (b) reacting the compound (III) with a compound RXH.Preferably, bromination is carried out rapidly in dried ethyl acetate.The process avoids hydration of the CN group of the compound (III) to a carbamoyl group obviating a subsequent dehydration step later.The intermediate compound (III) is novel.The substituted benzamides are useful as herbicides and fungicides.

  • Patent number: 4125879
    Abstract: The invention provides a computer store having successively addressed storage locations for individual words grouped together to form so-called clotheslines. Data can be written into and read out from either end of a clothesline. A clothesline thus combines the properties of a stack and a silo and can be considered as either a double-ended stack or as a reversible silo.
