Cone-beam C-arm CT systems allow to scan patients in weight-bearing positions to assess knee cartilage health under more realistic conditions. Involuntary patient motion during the acquisition results in motion artifacts in the reconstructions. The current motion estimation method is based on fiducial markers. They can be tracked with a high spatial accuracy in the projection images, but only d...

Quality-marker (Q-marker) is an emerging concept to ensure the quality and batch-to-batch consistency of Chinese medicine (CM). However, significant difficulties remain in the identification of Q-markers due to the unclear relationship between complex chemical compositions and the pharmacological efficacy of CM. In the present study, we proposed a novel strategy to identify the potential Q-mark...

Medicago sativa (alfalfa) is a widely used animal feed. However, its quality has been difficult to control due the lack of appropriate marker compounds. Therefore, it very necessary select an (Q-marker) quality. In this study, medium-pressure liquid chromatography and high-pressure were employed effectively prepare separation Q-marker (L-tryptophan) from sativa. Firstly, using MCI GEL® CHP20P a...

Eggshell quality is the main trait to assess egg quality. Marker assisted selection can be used to improve this trait. During eggshell formation, a mass of inorganic minerals is deposited. The Sodium Channel (SCNN1) gene family plays an essential role in cation transportation and SCNN1g is a member of this gene family. The objective of this study was to estimate the frequency of SCNN1g gene var...

background spirulina is one of the most profitable known microalgae in the world, which is used as food and superfood. in the other hand, spirulina is a useful source of healthy components. it seems that the spirulina is transformable so that the introduction of a selectable marker is needed. objectives the purpose of this study was to determine a suitable selection marker for spirulina platens...

Molecular marker-assisted selection (MAS) is currently being used to accelerate the development of rice cultivars with improved cooking quality and blast resistance at the University of Arkansas Rice Research and Extension Center (UA RREC) in Stuttgart. A co-dominant simple sequence repeat (SSR) marker, RM 190, is used to predict cooking quality of the milled grain, and a new automation-friendl...
