This is now known to be an oversimplification: certain sense organs in tunicates, for example, develop from placodes in a manner comparable to their vertebrate counterparts, and their development is regulated by a common suite of molecular factors (Mazet et al. 2005).
Epidermal nevi, of which the sebaceous nevus is an example, develop from the proliferation of normal epidermal tissues and are usually flesh-coloured or yellowish.
The new iPad app is a good example, developed in response to detailed feedback from Betfair's tablet-owning customers – Apps Blog sat behind the one-way glass at the company's focus-testing room in its London headquarters to watch one "VIP" user say in no uncertain terms what was lacking in its previous tablet apps, and how he'd like to use the updated version.
To understand resource recirculation in practice, this paper analyses over 50 examples of products developed from discarded materials, categorising them into the recovery routes described in the circular economy literature.
For some of the recent examples pharmacophores were developed from the 3D structure of a protein-ligand complex; in other cases the pharmacophore description was augmented with a criterion based on the observed shape of the binding site.
Two kinds of cell shape of the 3D auxetic material are studied as example, which are developed from the tetrachiral honeycombs with circular loops and square loops, respectively, with inclined rods connecting the neighbor layers.
Fig. 1 Example of a DHD developed from the paper one Fig. 2 Example of a HDD weekly report.
I provide a few examples of evolutionary hypotheses developed from the dated phylogeny in Figure 1, and compare these to the fossil record.
Early examples of anticancer agents developed from higher plants are the antileukemic alkaloids (vinblastine and vincristine), which were both obtained from the Madagascar periwinkle (Catharanthus roseus L.; Apocynaceae) [ 35].
One study, for example, developed a classifier of 48 miRNAs from a sample of 336 primary and metastatic tumours, and was able to use this classifier to accurately predict the tissue origin in 86% of a blind test set, including 77% of the metastatic tumours (Rosenfeld et al, 2008).
For example, implantable porous scaffolds developed from PLGA microspheres can be fabricated at 49 °C, with porosity levels ranging from 66 to 74% [29].
