Telomerase detection in body fluids.
BACKGROUND Telomerase is a ribonucleoprotein that maintains chromosomal telomere length. Telomerase is not active in nonmalignant somatic cells, but is activated in most human cancers. Telomerase activity in easily obtainable body fluids that bathe tumors may be a useful cancer marker, especially when used in conjunction with conventional cytology. APPROACH Results from studies that assayed t...
متن کاملDetection of Biomarkers in Tissues and Body Fluids
Biomarkers are present in all parts of the body including body fluids and tissues. Most of the clinical laboratory examinations are done on body fluids such as blood and urine. Biomarkers can be detected on imaging studies or examination of body tissues. Even exhaled breath contains biomarkers. A wide range of technologies is utilized for detection of biomarkers and a number of assays are alrea...

متن کاملOncomiR detection in circulating body fluids: a PDMS microdevice perspective.
There is an increasing interest in circulating microRNAs (miRNAs) as potential minimally invasive diagnostic biomarkers in oncology. Considerable efforts are being made in the development of lab-on-a-chip devices for biomedical applications to purify and detect miRNAs from biological fluids. Here, we report the development of an innovative polydimethylsiloxane (PDMS)-based parallel device whose...
متن کاملAcetylsulfisoxazole in Body Fluids
We describe a simple, rapid chromatographic method for separating and quantitatively determining sulfisoxazole and its N4-acetyl metabolite in plasma and urine. A 100-zL sample of plasma or urine is combined with 200 tL of a solution containing 12 mg/L of the internal standard, Nt acetylsulfamethoxazole, in absolute methanol and centrifuged to obtain a clear supernatant solution. This solution ...
