The MasSpec Pen is a mass spectrometry (MS) based cancer detection and diagnosis system that can be used for ex vivo [1] and in vivo [2] tissue sample analysis. The system collects biological molecules from a tissue sample surface via a solid-liquid extraction mechanism and transports the molecules to a mass spectrometer for analysis.
An injector pen (also called a medication pen) is a device used for injecting medication under the skin. First introduced in the 1980s, injector pens are designed to make injectable medication easier and more convenient to use, thus increasing patient adherence .
Tide is a tool to identify peptides from tandem mass spectra. It is an independent re-implementation of the SEQUEST algorithm, which identifies peptides by comparing the observed spectra to a catalog of theoretical spectra derived in silico from a database of known proteins.
In the paper, this method is proved to have better performance than other popular de novo peptide sequencing methods like PepNovo by a lot of example spectra. PEAKS is a complete software package for the interpretation of peptide mass spectra. It contains de novo sequencing, database search, PTM identification, homology search and ...
A mass chromatogram is a representation of mass spectrometry data as a chromatogram, where the x-axis represents time and the y-axis represents signal intensity. [1] The source data contains mass information; however, it is not graphically represented in a mass chromatogram in favor of visualizing signal intensity versus time.
Guided imagery (also known as guided affective imagery, or katathym-imaginative psychotherapy) is a mind-body intervention by which a trained practitioner or teacher helps a participant or patient to evoke and generate mental images [1] that simulate or recreate the sensory perception [2] [3] of sights, [4] [5] sounds, [6] tastes, [7] smells, [8] movements, [9] and images associated with touch ...
For each candidate peptide, Sequest projects a theoretical tandem mass spectrum, and Sequest compares these theoretical spectra to the observed tandem mass spectrum by the use of cross correlation. The candidate sequence with the best matching theoretical tandem mass spectrum is reported as the best identification for this spectrum.
Chromotherapy, sometimes called color therapy, colorology or cromatherapy, is an alternative medicine that is considered pseudoscience and quackery. [1] [2] ...
