Abstract: The invention provides a device for growing genetically enhanced aquatic photoautotrophic organisms in a stable culture, causing said organisms to produce ethanol, and then separating, collecting, and removing the ethanol in situ.

Abstract: The present invention discloses genetically-modified cyanobacteria with ethanol-production capabilities enhanced over the currently-reported art, and methods of making such cyanobacteria. The invention provides a genetically modified photoautotrophic, ethanol producing host cell comprising an overexpressed pyruvate decarboxylase enzyme converting pyruvate to acetaldehyde and an overexpressed Zn2+ dependent alcohol dehydrogenase enzyme converting acetaldehyde to ethanol.

Abstract: A sample of normal tissue specimens obtained from a subset of a population of subjects with shared characteristics is profiled in order to generate a plurality of structural indices that correspond to statistically significant representations of characteristics of tissue associated with the population. The structural indices include cell density, matrix density, blood vessel density and layer thickness. Alternatively, the sample of normal tissue specimens obtained from the subset of the population of subjects with shared characteristics can also be profiled in order to generate a plurality of cell function and/or mechanical indices that correspond to statistically significant representations of characteristics of tissue associated with the population. Structural, mechanical and/or cell function indices for a plurality of tissue populations are determined, and then stored in a database. The database information is then used to classify tissue specimens (e.g.

Abstract: A physics based model of the absorption of light by histological stains used to measure the amount of one or more stains at locations within tissue is disclosed. The subsequent analysis results in several improvements in the detection of tissue on a slide, improvements to autofocus algorithms so focusing during image acquisition is confined to tissue, improvements to image segmentation and identification of tissued and its features, improvements to the identification of stain where multiple stains are used, and improvements to the quantification of the extent of staining. The invention relates to the application of these improvements to stain detection and quantification to provide for objective comparison between tissues and closer correlation between the presentations of such features and concurrent patterns of gene or protein expression.
