Preferential orientations and related peak intensity modifications are also observable for precipitated OCP, but in this case the distinction from an apatite profile is more subtle.
The origin of the latter feature is unclear, but the line results from the rapid motion of the cantilever from its initial rest point (the center of the patterned area) to the starting position for writing lines, and it is possible that torsion of the cantilever as a result causes a localized modification in the exposure mechanism, yielding a broader band of low-intensity modification.
Increase of this peak intensity after modification by acetic acid is probably due to addition of methyl and methylene groups to side chains of acetylated lignin.
The questionnaire included 58 items for history including precise description of pain, provoking factors, duration, evolution, intensity, quality, modification with position, ancillary symptoms and open text to describe the chest pain as well as precise localisation on an anatomical map.
Kaplan Meier survival curves were made to visualise survival differences between high and low methylation groups (LINE-1) and high- and low-staining intensity (histone modifications), and significance was assessed using the log-rank test.
Univariate Cox regression analyses were performed to calculate differences in survival time and tumour recurrence between patients with a high or a low methylation index (LINE-1 and Alu) or staining intensity (histone modifications).
Applying the above steps to the array data and subsequently averaging replicate intensities), histone modification profiles for the four hematopoietic cell types were derived and subsequently investigated for their association with lineage commitment [ 28].
We additionally normalized the modification intensities by subtracting H3 intensities from the corresponding modification intensities to get specific values for each modification.
Fold change of PCNA modification intensity was analyzed using odyssey imaging systems.
The latter is leading to heterogeneous forest landscapes with predominant and varying intensity of human modification.
