How graded and segmental cues interact in specifying r1 precursors is key to understanding the origins of the cerebellum, a major structure in the higher vertebrate brain.
Prefrontal cortex (PFC) was noted as a major structure involved in both the pain and memory networks.
The finding of positive species associations after accounting for habitat and human use differences across sites appears to rule out negative interactions as a major structuring force in the presence or absence of species across reef sites.
Biological interactions have been identified as a major structuring force in taxonomic assemblages: Direct, competitive interactions between species are of particular significance for ecological structure and often result in checkerboard-like distribution patterns, particularly between closely related species [ 2].
On the other hand, we observed consequences of interspecific interactions on the spatial population structure of the mouse lemurs, which have been identified as a major structuring force in many taxonomic assemblages (trees [ 90], desert rodents [ 91- 93], pond snails [ 94], tadpoles [ 95]).
In marine benthic communities, seasonal and inter-annual variability in the quantity and quality of food supply is known to be a major structuring factor, especially in the deep sea [21], [22].
It is the city's only major structure in which a private preservation group was in effect an equity partner in the deal that transformed it into apartments, a hugely complex arrangement that provided more than $7 million over the years for a revolving loan fund to help brownstone owners and churches restore their landmark buildings.
The other one (Ssu05_0473), a putative pilin protein, is also an adhesin: pili are major structures participating in the adherence to and invasion of host cells [ 39, 44, 45].
A third major structure, completed in 2004, is the Ghazi Barotha hydroelectric project, located below Tarbela.
A major junctional structure in epithelial tissues is the "adherens junction," which is composed of cadherin adhesion receptors and associated proteins including F-actin.
