Alternatives: "as mentioned earlier" or "as stated before".
Target genes were normalized to GAPDH and quantified using the comparative CT method described by Livak et al. [ 39] and as used previously [ 36].
We chose to base our definition primarily on the presence of grade 1 osteophytes as required for a Kellgren-Lawrence grade of 1 and as used previously in this study and others.
The transcriptome and metabolome data presented here are as used previously (see [ 7] for details), while the proteome data comes from a reanalysis of the existing mass spectra using updated techniques.
The median age was 35 and we used this cut-off point for younger/older groups, as used previously from our qualitative studies conducted with Chinese community smokers, 20 allowing us to identify these differences in perspective.
This was the case where whether CGRP was measured with the same radioimmunoassay as used previously by Goadsby and Edvinsson [17, 18] or another sensitive assay [23].
These Q-factor values were obtained with N = 6 and with NTO and NTI having 4-hole sections, as used previously, together with small variations in the value of t3, as shown in Fig. 5.
The list of endogenous metabolites and marketed drugs was precisely as used previously [20 22], and we used the KNIME workflow environment (e.g. [66 72]) to write the appropriate workflows for these analyses.
In Experiment 2, the effect of the same enzyme as used previously (added at 0.51 μl/g forage DM, directly into the incubation medium), and buffer pH were examined using the ANKOM system, in a completely randomized design.
In an attempt to further explore and possibly improve the qualitative discrimination of the mango cultivars, PCA scores using cultivar type were developed with the same spectral regions and data pre-treatment as used previously; however, no crisp clustering of the PCA scores by cultivar type was observed (Fig. 4).
To assess the resolution of the model for line SPr2, we applied a checkerboard test (Fig. 7(b)) using the same procedure as used previously for lines OGr1 and SPr2 (Takahashi et al., 2009; Kodaira et al., 2010), but, here, we used a finer checkerboard pattern (i.e., a 10 km horizontal by 5 km vertical pattern to 15 km depth).
The siRNA sequence of the non-specific negative control was the same as used previously [8].
