Patent number: 10539580Abstract: Compositions and methods for detecting the presence and/or amount of one or more analytes, including analytes such as drugs of abuse, are provided. The compositions include two or more analytes associated with a solid phase, e.g., a particle or a multiwell plate. The compositions and methods also allow the simultaneous, tandem, or serial determination of the presence and/or amount of two or more analytes of interest in a sample.Type: GrantFiled: April 29, 2009Date of Patent: January 21, 2020Assignee: Psychemedics CorporationInventors: Virginia Hill, Mohammad Atefi, Michael I.

Patent number: 9261522Abstract: Methods for assessing the condition of keratinized structures, including hair, in particular methods to determine the condition of keratinized structures in relation to suitability for analysis of analytes of interest in a test sample, are presented. The methods comprise contacting the keratinized structure with a non-proteolytic reducing agent and an optional proteolytic agent. The methods further include inspection of the hair sample, or measurement of free protein eluted from the keratinized structure, after reduction and optional proteolysis to determine condition prior to analyte identification and quantitation by known techniques such as immunoassays.Type: GrantFiled: March 20, 2015Date of Patent: February 16, 2016Assignee: Psychemedics CorporationInventors: Virginia Hill, Michael I. Schaffer, Elvan Loni, Gary Neil Stowe

Patent number: 8435747Abstract: Methods that permit the rapid release of one or more analytes from head or body hair or other keratinized structures of an individual (who may previously have ingested one or more of the analytes) are provided. The methods can include contacting the keratinized structure with a reducing agent but not with a proteolytic agent. The methods can further include identification and quantification of the one or more analytes by known analytical techniques such as immunoassays. The described methods do not damage the analyte and do not cause harmful effects on a subsequently-used analyte detection probe (e.g., an antibody).Type: GrantFiled: April 29, 2009Date of Patent: May 7, 2013Assignee: Psychemedics CorporationInventors: Virginia Hill, Mohammad Atefi, Michael I.

Publication number: 20070260588Abstract: A method, apparatus and computer-usable medium for the selective, contextual retrieval and presentation of information used in review processes. Search criteria is entered for information to be retrieved for review and information source documents are then searched, maintaining references to the contextual levels encountered (e.g., chapter, section, sub-section, etc.). Once the search is completed, a hierarchical list of sentence extracts matching the search criteria and indicating their location in their respective source document is presented to the reviewer. The user can then select any level of the hierarchical view, which then displays an expanded view of the related section of the source document. The retrieved information can be exported to a plurality of formats, which are annotatable by the reviewer. Users are thereby provided with information relevant to the subject under review, structured and presented in the context of its usage within its associated source document.Type: ApplicationFiled: May 8, 2006Publication date: November 8, 2007Applicant: International Business Machines CorporationInventors: Ana Biazetti, Virginia Hill, Mary Sturgeon
