Increasing concentration and duration of Shh signal induces progenitors to acquire progressively more ventral fates.
As pointed out by de Queiroz [ 7], diverging lineages acquire progressively through time a number of different properties that allow their recognition as distinct species.
For example, tobacco, although tolerant to chloride, acquires progressively more undesirable burning characteristics of the leaf as well as reduced storage life if chloride levels in irrigation water increase above a few milliequivalents per litre.
More commonly in neoplasia, methylation increases in the CpG islands of genes as tumour suppressors are silenced and cancer cells acquire progressively more malignant properties (Lopez et al, 2009).
At the beginning of the 1980s the RS was conceived as system of learning through supervised and programmed professional practice for the specialist-in-training to acquire progressively the knowledge, skills, techniques and responsibilities needed to become an independent specialist.
Ring-fencing is clearly impractical when no knowledge of the reservoir populations exists, but other steps can be taken to acquire progressively more detailed information about the reservoir structure.
The hydrocarbon profiles, which are genetically and environmentally acquired, change progressively with age [ 75, 76].
Hence, the I-MPOS paradigm helps to standardize care in the field of medical genomics based on realistic expectations which evolve as new knowledge is acquired, thus progressively increasing the quality of care provided to patients.
Recording current/potential curves during the progress of the experiment confirmed that the cathode progressively acquired effective catalytic properties.
Laboratory tests have progressively acquired a dominant role in screening, diagnosis, disease monitoring and outcome assessment.
