The present analysis can be considered as an additional step in the sequential development of AD progression models.
The colorectal adenoma carcinoma sequence represents a well-known paradigm for the sequential development of cancer driven by the accumulation of genomic defects.
Although this approach represents a well-known paradigm for the sequential development of cancer driven by the accumulation of genetic defects, more and more cases of carcinogenesis have been reported in contrast to the linear and clonal development of cancer (Sedivy et al, 2000).
The framework consists of a main disease disability pathway, which describes the sequential development of pathology, impairment, functional limitation, and, finally, disability [ 5- 9].
In summary, we have used a novel conditional HRN model to investigate the sequential development of the phenotypic changes observed in mice on deletion of POR.
Two extreme possibilities implicate either a clonal origin with inherited molecular and phenotypic differences of oligo-or polymetastases, or sequential development of the metastatic process with oligometastases as an early but transient phase of polymetastatic disease (Fig. 1).
We therefore used this model to study the sequential development of the HRN phenotypic traits over a 28 day period following 3MC treatment.
It should also be kept in mind that biological events are not always strict and thus the proposed sequential development of pathology might be altered by a variety of factors and thus influence the staging results.
Following Hamilton (1967) LMC model, the seed in this species seems to function as a patch: (1) A single date seed of Phoenix datctylifera (averaging 3 × 1 cm) provides all the required nutrients for the sequential development of four to five clutches, with an average of 30 individuals per clutch (Gottlieb et al. 2011).
Strictly speaking, Poisson-statistics based models are incorrect biologically and that is why Niemierko's EUD and his sequential development of clustering algorithms [ 13] are so important in developing correct RT plans.
