摘要:
The invention provides compositions and methods of use in reprogramming somatic cells. Compositions and methods of the invention are of use, e.g., for generating or modulating (e.g., enhancing) generation of induced pluripotent stem cells by reprogramming somatic cells. The reprogrammed somatic cells are useful for a number of purposes, including treating or preventing a medical condition in an individual. The invention further provides methods for identifying an agent that reprograms somatic cells to a pluripotent state and/or enhances the speed and/or efficiency of reprogramming. Certain of the compositions and methods relate to modulating the Wnt pathway.

Methods and apparatus are provided for adaptively locking out a display on a vehicle device based on user interaction. A method begins by counting a number of user initiated display changes with an event counter, and timing the user initiated display changes with an event timer. The method continues by comparing the number of user initiated display changes in the event counter to an allowable number of user initiated display changes corresponding to the time in the event timer, and disabling the display for a display lockout time period if the number of user initiated display changes exceeds the allowable number of user initiated display changes.

A method of transforming slow-growing mycobacteria, such as M. bovis BCG, M. leprae, M. tuberculosis, M. avium, M. intracellulare and M. africanum; a method of manipulating genomic DNA of slow-growing mycobacteria through homologous recombination; a method of producing homologously recombinant (HR) slow-growing mycobacteria in which heterologous DNA is integrated into the genomic DNA at a homologous locus; homologously recombinant (HR) slow-growing mycobacteria having heterologous DNA integrated into their genomic DNA at a homologous locus; and mycobacterial DNA useful as a genetic marker.

The present invention relates to stress proteins and methods of modulating an individual's immune response. In particular, it relates to the use of such stress proteins in immune therapy and prophylaxis, which results in an induction or enhancement of an individual's immune response and as an immunotherapeutic agent which results in a decrease of an individual's immune response to his or her own cells. The present invention also relates to compositions comprising a stress protein joined to another component, such as a fusion protein in which a stress protein is fused to an antigen. Further, the present invention relates to a method of generating antibodies to a substance using a conjugate comprised of a stress protein joined to the substance.

An improved surface-mount electrical wire connector includes a connector housing and electrical contacts. The housing supports the electrical contacts and includes an upper surface with openings to receive the stripped ends of electrical wire. The upper surface includes an enhanced bearing surface established between a pair of openings by selectively chamfering the perimeter of the openings. This enhanced surface accommodates a suction-cup head on conventional pick-and-place assembly equipment. The electrical contacts include an upper section for receiving and retaining a wire and a lower section, extending through a lower surface of the housing, for solderably affixing the connector to a printed circuit board. The lower section of the contacts preferably include two, parallel, spaced apart members which provide four exposed surfaces to receive and retain solder.

This invention related to constructs comprising mutant HIV genomes having an alteration in a nucleotide sequence which is critical for genomic RNA packaging and non-infectious, immunogenic HIV particles produced by expression of these constructs in mammalian cells. Cell lines which stably produce non-infectious, immunogenic HIV particles are also included. Prophylactic and therapeutic vaccines, diagnostic reagents, and related methods are further described.
摘要:
The present invention relates to recombinant mycobacteria, particularly recombinant M. bovis BCG, which express heterologous DNA encoding a product (protein or polypeptide) of interest, such a protein or polypeptide (e.g., an antigen) against which an immune response is desired, or a cytokine.
