The diversity indices including AMOVA (analysis of molecular variance) based Fst analysis were calculated using ARLEQUIN 3.01 software [35].
In addition, molecular diagnostics based on analysis of biopsied or surgically resected tumor tissue is hampered by sampling error.
Moreover, molecular subtypes based on analysis of gene expression patterns [ 13] as well as more complex analyses of patterns of oncogenic and tumor suppressor pathway activity [ 14] have identified further subtypes that provide additional insight into the molecular and clinical heterogeneity of HER2+ tumors beyond the original ERBB2+ classification [ 1- 5].
This analysis showed a correlation (Pearson's Correlation Coefficient 0.80, R = 0.645) between the time of isolation of the individual isolates and the root-to-tip divergence, indicating a temporal signal for this dataset and justifying a molecular clock based phylogenetic analysis.
The proximal small intestines of healthy children and adults who live in relatively pristine environments in industrialized countries show only modest bacterial loads, whether measured by aerobic and anaerobic culture or by molecular techniques based on analysis of 16S rDNA sequencing of DNA from appropriate clinical specimens [ 77, 78].
Ne values estimated from molecular-based analysis were generally lower than those estimated from pedigree-based analysis, suggesting a loss of diversity between the onset of the conservation program (from 1983 to 1995) and the start of pedigree recording in 2002.
Molecular-based analysis using real time quantification method have revealed that cultured bacterial species represent only a small fraction of the total bacterial diversity (Janssen 2006; Stevenson and Weimer 2007).
These isolates were submitted to Stellenbosch University for molecular-based analysis.
In a previous immunophenotypic molecular-based analysis it was shown that bcl2 over-expression characterizes the SS gene profile in addition to the non-random translocations.
This idea was supported by our molecular-based analysis of the XDR TB isolates, which demonstrated that resistance to a fluoroquinolone had been acquired independently on several different occasions (several different gyrA mutations were observed), followed by amplification through transmission (clustering of XDR phenotypes was observed).
