Publication number: 20230098156Abstract: Biomarkers of high blood pressure are measured to identify high blood pressure of the subject based on one or more biomarkers. In many embodiments, the response of the biomarker to blood pressure occurs over the course of at least an hour, such that the high blood pressure identification is based on a cumulative effect of physiology of the subject over a period of time. The methods and apparatus of identifying high blood pressure with biomarkers have the advantage of providing improved treatment of the subject, as the identified biomarker can be related to an effect of the high blood pressure on the subject, such as a biomarker corresponding to central blood pressure. The sample can be subjected to increases in one or more of pressure or temperatures, and changes in the blood sample measured over time.Type: ApplicationFiled: August 12, 2022Publication date: March 30, 2023Applicant: COR HEALTH, INC.Inventors: Robert G.

Patent number: 8557031Abstract: This invention relates to methods for chemically grafting and attaching ceragenin molecules to polymer substrates; methods for synthesizing ceragenin-containing copolymers; methods for making ceragenin-modified water treatment membranes and spacers; and methods of treating contaminated water using ceragenin-modified treatment membranes and spacers. Ceragenins are synthetically produced antimicrobial peptide mimics that display broad-spectrum bactericidal activity. Alkene-functionalized ceragenins (e.g., acrylamide-functionalized ceragenins) can be attached to polyamide reverse osmosis membranes using amine-linking, amide-linking, UV-grafting, or silane-coating methods. In addition, silane-functionalized ceragenins can be directly attached to polymer surfaces that have free hydroxyls.Type: GrantFiled: January 7, 2011Date of Patent: October 15, 2013Assignee: Sandia CorporationInventors: Michael Hibbs, Susan J.

Patent number: 7202091Abstract: Systems and methods for establishing and/or maintaining the accuracy of a multivariate calibration model designed for quantitative optical spectroscopic measurement of attributes or analytes in bodily tissues, bodily fluids or other biological samples, which are particularly useful when the spectral absorbance of the attribute or analyte is small relative to the background. The present invention provides an optically similar reference sample to reduce the effect of instrument or environment variation on the measurement capability of the model. The optically similar reference can be a gel composition having scattering particles suspended therein. The reference gel can be directly applied to a spectroscopic instrument sampler, or can be in a container specifically designed for optimal coupling to a spectroscopic instrument.Type: GrantFiled: October 28, 2002Date of Patent: April 10, 2007Assignee: InLight Solutions, Inc.Inventors: Howland D.

Publication number: 20030087456Abstract: An apparatus and method for infrared spectral analysis of samples to determine if the samples are normal or abnormal or to otherwise classify the sample. More specifically, the apparatus and method classify the sample on the basis of attenuation of infrared radiation at different wavelengths using a within-sample variance model. Further, the method and apparatus can include merging the output of multivariate classification models with the within-sample variance model applied to the infrared spectra sample such that their combined output results in a classification accuracy that is greater than any single model. The invention is useful in classifying, for example, biological samples such as human tissue, including cervical cells.Type: ApplicationFiled: October 2, 2002Publication date: May 8, 2003Inventors: Howland D.T.
