To determine whether Sox2 haploinsufficiency renders cells more prone to differentiation, we performed lineage tracing analysis using Sox9 ires-CreERT2/+ ; R26R EYFP/+ ;Sox2 βgeo/+ animals.
This scheme is a collaboration between seven centres in the United Kingdom that perform trace element analysis using the same techniques and regularly monitor results between units to ensure reproducibility.
Convergence of the chain to stationary distributions was controlled by inspection of the MCMC samples (Trace) in each analysis using the program Tracer 1.5 (BEAST package), and 1000 trees (i.e. 10%) were discarded as burn-in prior to summarizing the posterior distribution of trees and indentifying the maximum clade credibility (MCC) tree using TreeAnnotator 1.6.1 (BEAST package).
We implemented our trace analysis algorithm using the Trace Compass trace viewer (previously TMF - Tracing and Monitoring Framework) [14].
From the top layer, fatty acid methyl ester was then taken for analysis using Trace GC (Thermo Finnigan, Rodano, Italy).
In fact, the impact of geothermal fluids in the shallow aquifer was identified from the application of the factor analysis using only trace elements.
Five grams of plant samples were extracted with carbon dioxide using the supercritical fluid extractor SFX System 1220R (ISCO, NE, USA), followed by GC-MS analysis using a Trace gas chromatograph interfaced to a Polaris Q mass spectrometer (Thermo Finnigan, Hertfordshire, UK) in EI mode (70 eV) as previously described [ 44].
As a means of evaluating the influence of uncertainty in inferred phylogenetic relationships and branch lengths, we reconstructed ancestral states across 1000 trees (every fifth of 5000 trees) sampled after attaining stationarity in the Bayesian analysis using the 'Trace Character Over Trees' option in Mesquite [ 26].
An optical analysis using ray-tracing tools was presented in a previous study in function of three design parameters: the number of mirrors N, the ratio of focal length and reflector width F/W, and the aperture concentration Ca. However, less is known about the thermal behavior of this geometry.
Determinants of renal and dopaminergic parameters studied were traced by stepwise multiple regression analysis using as independent variables log PbB, rank CdB, rank HgU, log AsU where applicable (Czech and Polish), log CreatU, log BMI, age, sex, and area of residence, as well as all first-order metal interaction terms.
