  • Publication number: 20200283851
    Abstract: Described are non-invasive methods of detecting in vivo cell death by measuring levels of ubiquitous and tissue specific miRNA. The method can be applied for detection of pathologies caused or accompanied by cell death, as well as for diagnosis of infectious disease, cytotoxic effects induced by different chemical or physical factors, and the presence of specific fetal abnormalities.

  • Patent number: 9163229
    Abstract: This invention provides compositions and methods for rapid isolation and purification of nucleopolymers from biological samples using anionic exchange media. The method of this invention can utilize commercially available anion exchanger materials with selected solutions of known ionic strength for absorption and elution. The medium/nucleoprotein bound complex may be optionally stored or transported, and is subsequently treated with eluents to remove undesirable proteins and inorganic salts. The partially purified complex may also be stored or transported. This method is particularly advantageous since it allows rapid isolation and purification of soluble nucleic acids from a large volume of biological fluids with easy handling and storage, stabilizing the samples against degradation prior to analysis. It also permits the purification and identification of shorter fragments of nucleic acids from bodily fluids which, until now, had not been identified.

  • Patent number: 8383335
    Abstract: The present invention relates to methods for diagnosis or monitoring of viral infection by detecting the presence of transrenal viral nucleic acids or nucleic acids of viral origin in urine sample, with or without isolation of nucleic acids from a urine sample. The analysis of the nucleic acids is performed through hybridization of the nucleic acids with specific probes, or through a chain amplification reaction with specific primers. The methods are applicable to all viral pathogenic agents, including RNA, DNA, episomal, or integrated viruses.

  • Publication number: 20120021412
    Abstract: The invention is based upon the discovery that small nucleic acids from non-viral pathogens are able to cross the kidney and are present in urine of a subject when the subject is infected with the non-viral pathogen. These transrenal DNAs are especially prevalent at smaller sizes under about 300 bp. Thus the invention provides compositions and methods for the diagnosis of infection of a subject with non-viral pathogens through the detection of transrenal nucleic acids from those pathogens in the urine of the subject.

  • Patent number: 7803929
    Abstract: The present invention relates to a method for diagnosing and/or monitoring a bacterial or parasitic infection by detection and quantification of the transrenal nucleic acids, derived from bacterial pathogenic agents or from parasites, in urine. The detection method optionally includes the isolation and the purification of the nucleic acids from urine by methods known in the art including pairing with molecular probes that are specific for the pathogenic agents, PCR hybridization, PCR, nested PCR, SSCP, LCR, and SDA. Diagnostic kits based on these detection methods are also claimed.

  • Publication number: 20080139801
    Abstract: This invention provides compositions and methods for rapid separation, isolation and purification of nucleopolymers, especially nucleic acids, from biological samples using anionic exchange media. The method of the present invention can utilize commercially available strong or weak anion exchanger materials with selected solutions of known ionic strength for adsorption and elution. The medium/nucleoprotein bound complex may be optionally stored or transported, but is subsequently treated with appropriate eluents to remove any undesirable proteins, including destabilizing enzymes, and inorganic salts and the like. The partially purified complex may also be stored or transported prior to further processing.
