    Abstract: The present invention relates to polypeptide fragments comprising an amino-terminal fragment of the PA subunit of a viral RNA-dependent RNA polymerase possessing endonuclease activity, wherein said PA subunit is from Influenza A 2009 pandemic H1N1 virus or is a variant thereof. This invention also relates to (i) crystals of the polypeptide fragments which are suitable for structure determination of said polypeptide fragments using X-ray crystallography and (ii) computational methods using the structural coordinates of said polypeptide to screen for and design compounds that modulate, preferably inhibit the endonucleolytically active site within the polypeptide fragment. In addition, this invention relates to methods identifying compounds that bind to the PA polypeptide fragments possessing endonuclease activity and preferably inhibit said endonucleolytic activity, preferably in a high throughput setting. This invention also relates to compounds which are able to modulate, preferably to inhibit, the endonuclease activity of the PA subunit polypeptide fragment or variant thereof of the present invention and pharmaceutical compositions comprising said compounds for the treatment of disease conditions caused by viral infections with viruses of the Orthomyxoviridae family, Bunyaviridae family and/or Arenviridae family, preferably caused by viral infections with Influenza A 2009 pandemic H1N1 virus. Preferably, said compounds are identifiable by the methods disclosed herein or said pharmaceutical compositions are producible by the methods disclosed herein.

    Abstract: A microscope and imaging method in which a layer of the sample is illuminated by a thin strip of light and the sample is viewed perpendicular to the plane of the strip of light. The depth of the strip of light thus essentially determines the depth of focus of the system. To record the image, the object is displaced through the strip of light, which remains fixed in relation to the detector, and fluorescent and/or diffused light is captured by a planar detector. Objects that absorb or diffuse a large amount of light are viewed from several spatial directions. The three-dimensional images, which are captured from each direction can be combined retrospectively to form one image, in which the data is weighted according to its resolution. The resolution of the combined image is then dominated by the lateral resolution of the individual images.

    Abstract: Tools are provided for obtaining and assessing data concerning the physical or behavioral traits of an biological specimen population for the purpose of identifying, treating, or gathering intelligence on the condition of the specimen population. In one aspect, a computer system is provided to assess a condition of a biological specimen by studying the physical traits of a sample that comprises a number of specimens. The condition may comprise a human central nervous system condition. A user interface is provided that comprises a computer screen, an input interface portion, and a processing mechanism. The user interface may further comprise a specimen information input mechanism. The specimen information input mechanism may comprise a specimen type input that allows the user to specify, through the computer screen input, the type of specimen to be studied.

    Abstract: A method of system is provided for assaying specimens. In connection with such system or method, plural multi-pixel target images of a field of view are obtained at different corresponding points in time over a given sample period. A background image is obtained using a plural set of the plural target images. For a range of points in time, the background image is removed from the target images to produce corresponding background-removed target images. Analysis is performed using at least a portion of the corresponding background-removed target images to identify visible features of the specimens. A holding structure is provided to hold a set of discrete specimen containers. A positioning mechanism is provided to position a plural subset of the containers to place the moving specimens within the plural subset of the containers within a field of view of the camera.
