Abstract:
The present invention provides a highly-safe information processing system that is capable of effectively using nucleotide sequence information differences between individual organisms to offer semantic information useful for each individual organism while properly preventing leakage and illegal use of nucleotide sequence information. Further, the present invention includes steps a and b. Step a is performed to acquire either encrypted nucleotide sequence-related information or cryptographic key that corresponds to positional information indicating a position within a nucleotide sequence. Step b is performed to acquire the encrypted nucleotide sequence-related information or cryptographic key, whichever is not acquired in said step a, decrypt, with the cryptographic key, the encrypted nucleotide sequence-related information corresponding to the positional information compliant at least with a request for an object and/or a service, and acquire the nucleotide sequence-related information corresponding to the positional information compliant at least with the request for an object and/or a service.
Abstract:
The present invention is a model for a mutually exclusive domain folding molecular switch comprising a two-domain, bifunctional fusion protein wherein the free energy released by the folding of a first domain of the fusion protein drives an unfolding of a second domain of the fusion protein, and vice versa. The molecular structure of the fusion protein is engineered so that, at any time, the folding of the first domain necessarily unfolds the other domain, and vice versa, thereby making the folded and unfolded states of the first and second domains mutually exclusive. This is accomplished by the insertion of an exemplary insert protein into a surface loop of an exemplary target protein subject to a novel structural design criterion wherein the N-C terminal length of the exemplary insert protein is at least two-times greater than the Cnull-Cnull length of the surface loop of the exemplary target protein.
Abstract:
The virtual screening of a database of molecules is based on explicit three-dimensional molecular superpositions. The torsional flexibility of the database molecules is taken fully into account, and an arbitrary number of conformation-dependent molecular features may be considered. A fragmentation-reassembly approach is utilized, which allows for an efficient sampling of the conformational space. A fast clique-based pattern-matching algorithm generates alignments of pairs of adjacent molecular fragments on the (rigid) query molecule that are subsequently reassembled to complete database molecules. Using conventional molecular features (hydrogen bond donors and acceptors, charges, and hydrophobic groups), it is possible to rapidly produce accurate alignments of medium-sized drug-like molecules. Examples with a test database containing a diverse set of 1780 drug-like molecules (including all conformers) show that average query processing times of the order of 0.1 seconds per molecule can be achieved on a PC, depending on the size of the query molecule.

Abstract:
An apparatus and method for preserving cytological specimens for histological or histopathological use. A cytological sample from a biological tissue such as a tumor or a tumor cell line is dehydrated, disbursed and evenly distributed throughout a volume of molten material. The molten material is then drawn into a tubular member such as a pipette and allowed to solidify. Upon solidification, the cylindrical specimen is partially or completely extrudedfrom the tube for further processing, including fixation, dehydration and molten paraffin infiltration and embedding as required for presentation to a sectioning device such as a microtome. Thin circular slices of the cylindrical specimen are removed from the cylindrical specimen and transferred to a slide, fixed and stained as desired. The device and method enable the production of a slide bearing a spatially homogeneous distribution of cytological material for microscopic examination.
Abstract:
A disclosed method of developing a drug comprises, in one embodiment: selecting a sub-group of constituent drugs from a potential group, wherein the selection is made on the basis that an expected effectiveness of a combination drug comprising all of the compounds of the selected sub-group exceeds a pre-determined minimum threshold measure of expected effectiveness against a target of the drug, and such that a side-effect measure for each expected side-effect of the combination drug is less than a corresponding pre-determined maximum threshold measure of side-effect tolerability for each side-effect; and selecting a dosage for each drug of the sub-group such that each dosage is less than a dosage that would be used as a fully effective dosage of the drug when used individually against the target of the drug. Related methods of treating patients, combination drug formulations, and computer-implementations of the methods are also disclosed.
Abstract:
Systems and methods for medical diagnosis or risk assessment for a patient are provided. These systems and methods are designed to be employed at the point of care, such as in emergency rooms and operating rooms, or in any situation in which a rapid and accurate result is desired. The systems and methods process patient data, particularly data from point of care diagnostic tests or assays, including immunoassays, electrocardiograms, X-rays and other such tests, and provide an indication of a medical condition or risk or absence thereof. The systems include an instrument for reading or evaluating the test data and software for converting the data into diagnostic or risk assessment information.
Abstract:
An unidentified purified protein can be uniquely identified by combining one or more physical parameters of the protein and an accurate amino acid content. The protein can be identified by input of the one or more physical parameters and the amino acid content into an interface that outputs data from a protein database.
Abstract:
A method of detecting binding interactions and target molecules, such as proteins, protein fragments, recombinant proteins, recombinant protein fragments, extracellular matrix proteins, ligands, carbohydrates, steroids, hormones, drugs, drug candidates, immunoglobulins and receptors of eukaryotic, prokaryotic or viral origin, by mediated electrochemistry using labels that react with transition metal mediator complexes in a detectable catalytic redox reaction. These labels are attached directly to binders, target molecules, surrogate target molecules, or to affinity ligands capable of binding to the target or to surrogate target molecules capable of competing with the target for binding to another binder. The labels can be naturally present (endogenous) in the binder, target or affinity ligand, or constructed by the covalent attachment of the label to the binder, target, affinity ligand or surrogate target (exogenous).
Abstract:
Methods of determining the amount of an analyte in a mixture of analytes are provided. The methods involve contacting a sample of analytes that is labeled with two or more distinguishably detectable labels with a probe for the analyte, and determining the amounts of the two or more distinguishably detectable labels bound with the probe. In certain embodiments, the methods include averaging the amounts of the two or more labels in order to determine the amount of analyte in the sample. Kits are provided for performing the invention. The subject invention finds use in a variety of different applications, including gene expression analysis, DNA sequencing, mutation detection and other genomics and proteomics applications.
