Abstract: The present invention relates to a method for diagnosing, in vitro, a neurodegenerative disease in an individual, in which: the level of the double-stranded RNA-dependent protein kinase (PKR) in a sample of cerebrospinal fluid from the individual is determined; it is deduced therefrom whether the individual is suffering from a neurodegenerative disease.

Abstract: A system for restricting access to television programs comprising an input for accepting cursor movement and selection commands. In one embodiment, the system displays a list of television viewers to be selected to limit their television program viewing based on a selecting blocking criterion. The system further includes means for blocking or allowing viewing of television programs based on time or dollar allowance when a selection command is entered into the input.

Abstract: A system for restricting access to television programs comprising an input for accepting cursor movement and selection commands. The system includes a display that depicts a two dimensional matrix composed of rows and columns of tiles, wherein either the rows of tiles or the columns of tiles correspond to overall program ratings and either the rows of tiles or the columns of tiles correspond to specific program content indications and depicts highlighting of individual tiles or groups of tiles based on the cursor movement commands. The system further includes means for blocking or allowing viewing of television programs based on the overall program ratings and specific content ratings of the rows and columns corresponding the highlighted tiles when a selection command is entered into the input.

Abstract: A system and method are provided for restricting access to a television by providing parental control functions. Separate parental control levels are set for different users with each user having a different password. When the television is initially turned on, the default parental control level chosen is to be the level that corresponds with the most restrictive parental control level. If another user with a less restrictive parental control level wishes to change the parental control level, they enter their password for their level of parental control.

Abstract: The present invention concerns a method and kit for determining if a subject is at increased or decreased risk of developing Alzheimer's disease. The invention further concerns vectors, transformed cells or transgenic mammals which can be used in a method for the screening of compound capable of modulating the expression of the GluR-5 gene or the activity of the GluR-5 receptor. The compounds selected by the method of the invention, as medicament for the treatment or the prevention of Alzheimer's disease, also form part of the present invention.
