Furthermore, we did not assess specific end-points of fecundability such as menstrual cycle characteristics, markers of ovulation or semen quality (Buck Louis et al., 2014).
Now, instead of a bone puncture, the donor is injected with a cytokine that makes the stem cells proliferate and enter the bloodstream, where they can be captured by virtue of characteristic marker proteins they carry on their surface.
It was found that the presence of acrylamide resulted in a characteristic marker SERS peak that did not exist in the background SERS spectrum of the sensor.
The position of an absorption edge in each reconstructed voxel spectrum is used as a characteristic marker, enabling chemical elements to be mapped in 3D. Figure 1: Hyperspectral XCT: A regular area detector in a commercially available microtomography scanner is replaced with a spectroscopic imaging detector with a high energy resolution.
β-Wollastonite is a characteristic marker used to discrimination between soft- and hard-paste porcelains.
Thus, the fragment ions at m/z 685, 671 or 681 are characteristic marker ions for identification of surfactins.
Furthermore the comparison of all the produced pyrograms allowed defining characteristic marker compounds helpful to discriminate specific PU paint systems.
Gastrointestinal leiomyosarcoma (LMS) is a rare entity that could not be accurately diagnosed until c-kit, a characteristic marker of gastrointestinal stromal tumor (GIST), was discovered in 1998 [1].
Previously, LMS was not properly distinguishable from gastrointestinal stromal tumor (GIST) until c-kit, a characteristic marker of GIST, was discovered in 1998.
Furthermore, peak a is one of characteristic marker in chromatogram of callus, whereas it could not detected in chromatogram of mature plant.
