An analytic apparatus and method is provided for diagnosis, prognosis and biomarker discovery using transcriptome data such as mRNA expression levels from microarrays, proteomic data, and metabolomic data. The invention provides for model-based analysis, especially using kernel-based models, and more particularly similarity-based models. Model-derived residuals advantageously provide a unique new tool for insights into disease mechanisms. Localization of models provides for improved model efficacy. The invention is capable of extracting useful information heretofore unavailable by other methods, relating to dynamics in cellular gene regulation, regulatory networks, biological pathways and metabolism.

This invention is to use knowledge pattern learning and search system for selecting microorganisms to produce useful materials and to generate clean energy from wastes, wastewaters, biomass or from other inexpensive sources. The method starts with an in silico screening platform which involves multiple steps. First, the organisms' profiles are compiled by linking the massive genetic and chemical fingerprints in the metabolic and energy-generating biological pathways (e.g. codon usages, gene distributions in function categories, etc.) to the organisms' biological behaviors. Second, a machine learning and pattern recognition system is used to group the organism population into characteristic groups based on the profiles. Lastly, one or a group of microorganisms are selected based on profile match scores calculated from a defined metabolic efficiency measure, which, in term, is a prediction of a desired capability in real life based on an organism's profile. In the example of recovering clean energy from treating wastewaters from food process industries, domestic or municipal wastes, animal or meat-packing wastes, microorganisms' metabolic capabilities to digest organic matter and generate clean energy are assessed using the invention, and the most effective organisms in terms of waste reduction and energy generation are selected based on the content of a biowaste input and a desired clean energy output. By selecting a microorganism or consortia of multiply microorganisms using this method, one can clean the water and also directly generate electricity from Microbial Fuel Cells (MFC), or hydrogen, methane or other biogases from microorganism fermentation. In addition, using similar screening method, clean hydrogen can be recovered first from an anaerobic fermentation process accompanying the wastewater treatment, and the end products from the fermentation process can be fed into a Microbial Fuel Cell (MFC) process to generate clean electricity and at the same time treat the wastewater. The invention can be used to first select the hydrogenic microorganisms to efficiently generate hydrogen and to select electrogenic organisms to convert the wastes into electricity. This method can be used for converting wastes to one or more forms of renewable energies.

Methods and kits are provided for assessing radiation injury and exposure in a subject. The methods comprise measuring the levels of at least two (2) protein biomarkers from different biological pathways and correlating the levels with an assessment of radiation injury and exposure. Additional use of peripheral blood cell counts and serum enzyme biomarkers, evaluated in the early time frame after a suspected radiation exposure, and use of integrated multiple parameter triage tools to enhance radiation exposure discrimination and assessment are also provided. The information obtained from such methods can be used by a clinician to accurately assess the extent of radiation injury/exposure in the subject, and thus will provide a valuable tool for determining treatment protocols on a subject by subject basis.

The present invention describes methods for carrying out experiments on living cells, including making measurements of the operation transcriptional regulatory processes and indicators of the kinds of processes operating in the cell in response to external stimuli. Image analysis allows for gathering data concerning the flow of information through a cell's genomic regulatory network as it is executing a programmatic change in its activities as a function of said stimuli. The method also allows collection of data of the results of the information-processing in the cell by observing the decisions the cell makes when modulating cellular process activities.

Provided herein is a system and method for analyzing microarray data (transcriptome profiles), metabolite data (metabolome profiles), protein level data (proteome profiles), or any combination thereof to determine the biochemical pathways affected by a treatment. The system and method can be used to generate biochemical pathway information for any organism for which metabolic profile data can be obtained.
