The authors used a clever genetic trick to replace β-catenin in muscle cells with mutant versions that either cannot mediate cell adhesion or cannot activate downstream genes and showed that a transcription based mechanism in the muscle cells requiring β-catenin regulates the presynaptic differentiation in the motoneurons.
Drosophila olfactory neurons usually display background firing in the absence of odorants, cAMP dependent eag activation might provide an OR based mechanism of homeostatic plasticity in the periphery of the olfactory system, and could adjust the neurons to a desired output range.
Given this conservation, the nucleosome positioning code almost certainly predates the Eukaryotes, and co-evolved with histones and the histone-fold based mechanism of DNA compaction early in the archaeal lineage, before the divergence of Euryarchaea, Nanoarchaea and Thaumarchaea[ 9- 11].
And it was America that argued for including market-based mechanisms in the deeply-flawed Kyoto treaty.
The Dutch government is also planning to introduce more incentive-based mechanisms in the currently regulated domain.
21 Despite targeting arguably one of the most important analgesic receptor-based mechanisms in the brain, these drugs are competing with the patients' own endogenous pain-relieving systems.
However, the likely considerable role of 'epigenetics'-based mechanisms in the regulation of these diverse biological processes has yet to be fully investigated [ 2].
The data in birds also suggests a key role for recombination-based mechanisms in the generation of chromosome rearrangements in that EBR location is consistent with elevated levels of genetic recombination at these loci [ 14].
One of these is generated by an initial NAHR event between inverted repeats, and the other occurs by a nonhomologous mechanism, potentially a DNA replication-based mechanism that results in microhomology at the breakpoint junction [ 5].
Experimental results on the two sets of SAR data indicate that the proposed method has better performance than traditional decompositions based on scattering mechanisms in the classification of SAR images.
In this work we consider asymptotic solutions, based on the dominant mechanisms, in the case of coffee extraction from a dilute suspension of coffee grains.
