However, eventual irregular markers at this site are subsequently discarded.
For proper construction of a regular tree, all irregular markers should first be recognized and excluded from further analysis, so that a strict consensus of compatible markers remains.
Fast-changing sites usually imply the appearance of many irregular markers in the data set, leaving paucity of regular ones for construction of the SMCC tree.
Once a regular tree has been formed, irregular markers could be used for elucidation of the natural history of reversions, parallelisms and also recombinations.
Markers included in this minimal combination are designated as irregular (homoplastic) markers, while the rest represents the maximal combination of compatible characters.
Earlier menarche and irregular periods, among other markers of sex-hormone levels, have been associated with a higher risk of asthma and allergic diseases.
This observation may be due to the presence of hepatic IR and consequently irregular secretion of these markers by hepatocytes as liver is considered to be the main source of most of these biochemical markers.
The integrity of the cells and the intercellular space was lost, and there was an irregular accumulation of the CD15 marker in circumscribed tissue areas.
Despite the subjective variations in margin interpretation, an irregular margin is a useful marker of malignancy with high accuracy, specificity and positive predictive value of 73.4%, 83 91.8%, 60 81.3%, respectively.
In conclusion, metabolic markers show a strong but irregular relation with hypoxia with obvious correlations between markers, emphasizing the complex metabolic regulatory system with a strong environmental (hypoxia, pH) influence.
In contrast, the distribution of approximately 300 previously mapped AFLP markers was highly irregular.
