However, 4 independent studies using Arabidopsis as a model system indicated that at the phylum level, core communities such as Actinobacteria, Bacteriodetes and Proteobacteria can be found in all roots independent of soil type and genotypes, 2,4,5-7 strongly indicating that bacteria do not randomly colonize roots, but certain phyla preferentially colonize plant roots.
While these two processes are coordinated, and both are driven by 5-HT, they occur on a very different time scales in this model system, indicating that they depend on different mechanisms.
Evidence from model systems indicates the ligand-independent activity of the hotspot ESR1 mutations.4,27,28,29 Our clinical data on the significantly higher expression of ERGs when ESR1 mutations were present, despite the on-going treatment with AI, supports this being valid in clinical tissues.
Calculations for small many-electron model systems indicate the existence of finite two-body parameters that produce the numerically exact wave functions for ground and excited states.
Ab-initio calculations in CNT model systems indicate that the Diels-Alder addition of butadiene is a feasible process and that subsequent oxidation reactions may result in the formation of the anhydride moiety.
Comparison of the two model systems indicates that only a dedicated Cu ZrOxHy interface with in situ formed and reversibly hydroxylated sites (accessible only from initially (inter)metallic Cu/Zr species at the surface) leads to water activation, total oxidation of intermediate formaldehyde, and enhanced CO2 selectivity.
Studies in model systems indicate that neural activity may also promote dependency on internal initiation of translation.
On the other hand, cells with very high (>200 DMs) were extremely rare in our model systems, indicating some degree of selection against cells with an extremely high DM copy-number.
Support for this model includes the multiphoton laser experiments shown here (Figures 11 and 12), as well as evidence in other model systems indicating that loss of UNG2 results in increased sensitivity to ionizing radiation [23], [58], which primarily produces double-strand breaks.
However, cellular model systems indicate arsenic can induce malignant transformation of human prostate epithelial cells in vitro.
Studies that use different model systems indicate an important interplay between the exocyst and small GTPases, which regulate many steps in intracellular membrane traffic (Mizuno-Yamasaki et al. 2012).
