detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Single-molecule real-time detection of telomerase extension activity
The ends of eukaryotic chromosomes are capped by telomeres which consist of tandem G-rich DNA repeats stabilized by the shelterin protein complex. Telomeres shorten progressively in most normal cells due to the end replication problem. In more than 85% of cancers however, the telomere length is maintained by telomerase; a reverse transcriptase that adds telomeric TTAGGG repeats using its integr...
متن کاملReal-time quantitative telomeric repeat amplification protocol assay for the detection of telomerase activity.
BACKGROUND Telomerase is a ribonucleoprotein enzyme associated with immortalization and transformation of human cells. The telomeric repeat amplification protocol (TRAP) is widely used for the detection of telomerase activity. The TRAP method, although highly sensitive and specific because it includes PCR amplification, is laborious and does not provide precise quantitative information. METHO...
متن کاملCytological detection of telomerase activity using an in situ telomeric repeat amplification protocol assay.
A previously reported highly sensitive assay for measuring telomerase activity on cell and tissue extracts indicates that most human tumor tissues, but not cells adjacent to tumors, have detectable telomerase activity. Although this assay has provided a significant amount of information about the presence or absence of telomerase activity, it does not indicate whether all cells within a tumor h...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
