• biomarkers
  • This manuscript summarises the scientific evidence on the use of biomarkers to measure SHSe, analytical methods, biological matrices and their interpretation. (pubmedcentralcanada.ca)
  • The authors note that while biomarkers have certain theoretical advantages over environmental measurements for epidemiologic studies, very few relevant applications have been published, one reason being the difficulty of collecting and assaying biological specimens from large numbers of exposed persons. (cdc.gov)
  • Discussions with regulatory authorities gain momentum defining the role of tau biomarkers for trial designs and how they may be further qualified for surrogate marker status. (pubmedcentralcanada.ca)
  • diagnostic markers
  • The research team recruited more than 700 patients with psychosis and some of their first-degree relatives--a parent, sibling or child--as well as a control group of healthy individuals to see if they could identify brain-based diagnostic markers to differentiate these conditions. (eurekalert.org)
  • chronic
  • A recent study indicates that apomorphine might be a suitable marker for assessing central dopamine system alterations associated with chronic heroin consumption. (wikipedia.org)
  • cancer
  • A recent article showed that insulin and leptin, biological markers of obesity, may correlate with cancer risk in Barrett's esophagus patients. (prweb.com)
  • Now we can link cancer even more closely to biological markers, which will give us a more advanced knowledge of the course of progression," explained Mark Davidson, MD, another director at the Barrett's Esophagus Center of Excellence. (prweb.com)
  • potential
  • For example, there are a number of good potential markers in the rise and decline of "Christmas tree" stromatolites, in the ebb and flow of banded iron formations, the appearance of stable carbon-13 isotope (13C) excursions, and so on. (wikipedia.org)
  • blood
  • Biological markers associated with obesity include leptin, a regulator of hunger, and insulin, a regulator of blood sugar levels. (prweb.com)
  • When Aβ peptide is released by proteolytic cleavage of amyloid precursor protein, some Aβ peptides that are solubilized are detected in CSF and blood plasma which makes AB peptides a promising candidate for biological markers. (wikipedia.org)
  • Study
  • The biological marker identified in the study was the length of telomeres-cap-like protein complexes at the ends of chromosomes-which shorten with age. (nih.gov)
  • patients
  • Czerwionka M, Korf H-W, Hoffmann O, Busch H, Schachenmayr W (1989) Differentiation in medulloblastomas: correlation between the immunocytochemical demonstration of photoreceptor markers (S-antigen, rod-opsin) and the survival rate in 66 patients. (springer.com)
