20150369807 | METHODS AND DEVICES FOR DETERMINING A DISEASE STATE - The present invention, in some embodiments thereof, relates to methods and devices for determining a disease state in a patient. In some embodiments, human serum albumin may be analyzed for associated molecules, wherein the associated molecules are related to a disease such as cancer. Certain aspects of the invention are generally directed to devices and methods for determining a disease state as a function of the three-dimensional structure of a blood protein, human serum albumin (HSA) or its complex with other ligands, e.g., due to binding to disease-specific ligands. HSA interacts with biomolecules associated with a disease presence, and liganded HSA may differentially partition between aqueous phases of a predetermined partitioning system, wherein the partitioning behavior differs between HSA from healthy individuals and HSA from people harboring the predetermined disease, such as breast cancer. | 12-24-2015 |
20150220700 | METHODS AND DEVICES FOR DETERMINING OPTIMAL AGENT DOSAGES - The present invention is generally directed to methods and devices for determining dosing for a medical agent. In some embodiments, a mathematical algorithm is employed for computing erythropoiesis-stimulating agents dosing for treating anemia in a subject, e.g., a human subject. Any suitable dosing may be used, e.g., intravenous, subcutaneous, or oral dosing. In some cases, dosing for a wide range of subject types and health conditions can be achieved using the devices and methods disclosed herein. | 08-06-2015 |
20150219655 | METHODS AND DEVICES FOR ANALYZING SPECIES TO DETERMINE DISEASES - The present invention, in some embodiments thereof, generally relates to methods and devices for determining the health status of a subject, e.g., whether the subject has a disease or other condition. In some embodiments, a plurality or mixture of species may be differentially solubilized in a single two-phase aqueous system, or other multi-phase aqueous system. The nature or degree of the solubilization of the species may be used to determine the health status of a subject. For example, some embodiments are directed to devices and methods for determining a disease or other condition as a function of the changes to the structure of two or more species. The species may be selected based on their differential solubility behavior in a two-phase or other multi-phase aqueous system. Preferential enrichment of the species concentrations in one of the phases, and/or the ratios of species in the phases may be determined, and in some cases compared to their respective values for healthy and/or diseased subjects to determine the health status of the subject. | 08-06-2015 |
20150160246 | DEVICES AND METHODS FOR DETERMINING AND/OR ISOLATING CELLS SUCH AS CIRCULATING CANCER OR FETAL CELLS - Some embodiments of the present invention generally relate to devices and methods for determining and/or isolating cells. For example, one aspect is generally directed to methods and devices for detecting, identifying, counting, and/or potentially sorting cells of interest in blood or other biological sample. In some embodiments, blood samples (or other biological fluids) may be treated with signaling entities, such as pH-sensitive entities, that change color or otherwise produce a signal in suitable internal environments. For example, certain cells, such as cancer or fetal cells, may have differences in intracellular pH compared to other cells, which can be detected using pH-sensitive entities. In certain embodiments, the cells may be sorted based on such signaling entities; for example, illumination of cells in a suitable machine for sorting cells (e.g., using fluorescent light) may allow determination of the cells, which may also be recovered or isolated for further manipulation in some cases. | 06-11-2015 |

20140065642 | SYSTEMS AND METHODS FOR CHARACTERIZATION OF MOLECULES - The present invention generally provides systems and methods for the detection, identification, or characterization of differences between properties or behavior of corresponding species in two or more mixtures comprised of molecules, including biomolecules and/or molecules able to interact with biomolecules, using techniques such as partitioning. The experimental conditions established as distinguishing between the mixtures of the molecules using the systems and methods of the invention can also be used, in some cases, for further fractionation and/or characterization of the biomolecules and/or other molecules, using techniques such as single-step or multiple-step extraction, and/or by liquid-liquid partition chromatography.

After fractionation, different phases of a partitioning system can be analyzed via an analytical technique such as spectral analysis, chromatography, or the like, to produce a spectrum or other symbolic representation of the species after fractionation, and the spectra of the various fractions/phases compared to define a comparative spectrum as a marker or otherwise providing information about the sample, including such information that is independent of the original level of abundance of the molecules in the mixture. Comparative spectra of various samples can be compared to each other and/or to controls or reference spectra and/or comparative spectra to determine a variety of information. In some embodiments, the methods can be used for discovering and/or identifying patterns in a mixture of species and/or corresponding patterns of species in a second mixture, where each mixture of species originates from biological systems with different physiological conditions as markers associated with specific diagnostics, and can be used for screening for such markers once discovered and identified during diagnostics screening. | 12-08-2011 |
