Wheat is one of the most important cereal crops for human beings, with seeds being the tissue of highly economic value. Various morphogenetic and metabolic processes are exclusively associated with seed maturation. The goal of this study was to screen and identify genes specifically expressed in the developing seed of wheat with an integrative utilization of digital differential display (DDD
Enrichment culture is the use of certain growth media to favor the growth of a particular microorganism over others, enriching a sample for the microorganism of interest. This is generally done by introducing nutrients or environmental conditions that only allow the growth of an organism of interest.

Mar 07, 2017· Abstract. Ultrahigh-throughput screening (uHTS) techniques can identify unique functionality from millions of variants. To mimic the natural selection mechanisms that occur by compartmentalization in vivo, we developed a technique based on single-cell encapsulation in droplets of a monodisperse microfluidic double water-in-oil-in-water emulsion (MDE).
ROC curve and enrichment factors seems to be the most used methods. But my question now (might seem a little bit silly) is: is it mandatory to use any of these methods in a virtual screening protocol?
ences. This review introduces a new method for genetic difference screening — the primer extension enrichment reaction (PEER) — presented in the context of simi-lar subtraction-based hybridization methods. PEER is a novel approach to differ-ence screening and is not intended to replace the existing elegant hybridization
The SEB method in the porcine samples resulted in a sensitivity (0.71) comparable to the standard method (P= 0.31). In conclusion, additional pre-enrichment of samples in UB may substantially increase the culture sensitivity. During routine screening of large numbers of samples, it may be advantageous to use SEB rather than standard culturing.
Enrichment is the prospective use of any patient characteristic to select a study population in which detection of a drug effect (if one is in fact present) is more likely than it would be in an
