Another potential response to maximise size at important life-history events, is to increase the time available for growth prior to metamorphosis or reproduction by extending development over multiple growth periods [ 18].
Atari was experiencing severe financial troubles at the time and could not extend the game's development period as it would have left their production factory idle.
As a case in point, loss of the brain-secretory polypeptide prothoracicotropic hormone (PTTH) delays larval development, extends the feeding period and leads to a concomitant increase in body size (McBrayer et al., 2007).
Using the strength of spatio-temporally controlled gene missexpression in avian embryos, we report that Notch harbors distinct pro-smooth muscle activities depending on the duration of the signal; short periods prevent striated muscle development and extended periods, through Snail1, promote cell emigration from the dermomyotome towards a smooth muscle fate.
However, satellite radar is already used to assess the development of extended periods of unrest and long-lasting eruptions, and improved spatial resolution and coverage have resulted in the detection of previously unrecognised deformation at both ends of the spatial scale (~ 10 to > 1000 km2).
Although only single representative staged specimens are presented here, the observed trends were consistent over extended periods of larval development.
Animals were observed for xenograft and/or aggressive metastatic disease development for extended periods of time (Min 15; Max 60 days).
In contrast, both pelagic notothenioid species exhibited strong expression of this cartilage marker through extended periods of larval development (Fig. 3A and 3B).
In notothenioids, the pterygoid process is conspicuously absent throughout extended periods of larval development, and in adults this structure (i.e., ectopterygoid) is greatly reduced in size [ 13].
Here we show that the evolution of bone loss in Antarctic notothenioids can be explained in part by the prolongation of the early chondrogenic developmental pathway through extended periods of larval development.
Exposure of OV-1063, UCI-107 and ES-2 ovarian carcinoma cells to RC-3940-II RC-3940-II RC-3940-II for 24 h in vitro, extended the latency period for the development of palpable tumours in nude mice.
