Because axolotls retain basal vertebrate traits, we propose that the last cell standing model may define the basal state for PGC specification in embryos of all vertebrate lineages, mammals notwithstanding.
Fish in the family Poeciliidae, which includes the guppy and close relatives (Poecilia spp ., as well as swordtails and platyfishes (Xiphophorus spp ., are long standing models for the study of sexual selection, as both male secondary sexual characteristics and female mate choice are highly variable traits within the group [ 19- 23].
While residencies are the long-standing model for Las Vegas, this unending demand for live music is spreading the model across the entire country.
The long-standing model for the hydrophobic factor (free energy change proportional to buried non-polar surface area) is contrasted with the packing desolvation model and the approximate nature of the proportionality between free energy and apolar surface area is discussed.
In a previous study, we identified a member of angiotensin converting enzyme (ACE) gene family, collectrin, by its up-regulation in a mouse model of partial nephrectomy [1], which is a long-standing model for the progressive renal diseases.
The quality factors are also examined in terms of long-standing models for the mechanism of auxin binding.
For example, we know that pigeons (Columba livia), long-standing models for avian navigation, rely on individually distinct routes when homing from familiar sites.
Our experiments address two long-standing models for the function of the Drosophila brain circadian network: a dual oscillator model, which emphasizes the primacy of PDF-containing neurons, and a cell-autonomous model for circadian phase adjustment.
This provided the basis for a long-standing model of size control where cell size triggers replication initiation, which in turn determines the timing of division (see [ 10] and references therein).
The animals we chose for our study were the larvae of two long-standing model species for insect cold hardiness the freeze-avoiding gall moth Epiblema scudderiana and the freeze-tolerant gall fly Eurosta solidaginis.
