Abstract: An X-ray imaging apparatus includes an X-ray source configured to generate X-rays, and to irradiate the X-rays; an imaging unit configured to photograph an object image; a controller configured to acquire object direction information from the object image, and to determine whether the object direction information corresponds to information about an irradiation direction of X-rays; and a user interface configured to output a warning if the object direction information does not correspond to the information about the irradiation direction of X-rays.

Abstract: The present invention features molecules that relate to SYNGAP (Synaptic GTPase Activating Protein), an excitatory synapse protein that has been found to bind synaptic proteins and modulate signal transduction. In one aspect, the invention provides isolated polynucleotides that encode SYNGAP or fragments or derivatives thereof. Further provided are SYNGAP or SYNGAP-related polypeptides encoded by the polynucleotides. In another aspect, the invention provides immunological molocules that are capable of binding the polypetides. Additionally provided are methods for using the molocules of this invention, e.g., to treat or prevent a disorder mediated by SYNGAP. The invention also provides screening assays for detecting compounds useful in the diagnosis or treatment of disorders impacted by SYNGAP.
