Of the antioxidant evaluation methods used, the DPPH assay, based on the reaction of the stable free-radical (2,2-diphenyl-1 picrylhydrazyl) with components of the sample, evaluating a change in the color of the solution, is the most frequently used.
[5] For optimal precision in measurements of noble gas abundances and isotope ratios, these species must be concentrated in the atmospheric sample through removal of active gases with components of SAM's gas-processing system [ Mahaffy et al., 2012].
We found all targeted PBDE congeners in at least 50% of samples, with the components of PentaBDE (BDE 47 and BDE 99) and DecaBDE (BDE 209) mixtures in 100% of samples.
This procedure ensured the examination of tissue samples with predominant components of the respective tumors (>80%).
Realistic Swarm satellite trajectories were simulated for the same period, the external and induced fields were synthetized along the tracks with 1 Hz sampling rate, together with other components of geomagnetic field (main, litho-spheric, ionospheric and corresponding induced field), as well as a model of instrument noise.
The examination was done in tissue samples with predominant components (>80 %) of the individual tumor entities (e.g., embryonal carcinoma, immature teratoma, etc).
Unfortunately, the low number of cases, high cytogenetic variability and tumour population heterogeneity, as well as the contamination of samples with stromal components, might render this analysis difficult to interpret and highly variable across studies.
A jujube extract sample with unknown levels of volatile components was analyzed using the developed method.
The sample was then mixed with the components of the Nimblegen Hybridization Kit (Hybridization buffer, component A, and alignment oligo) and incubated at 95°C for 5 minutes before being loaded onto the NimbleGen microarray.
The utility of the amino groups seemed to be higher for the sample with lower contents of organic component between the graphite oxide layers and larger interlayer spacings.
The resulting spectrum from the integrating sphere would represent the absorption component of the particulate sample with the scattering component being accounted for as background.
