The chicken embryo is a unique model that overcomes many limitations to studying the biology of cancer in vivo. The chorioallantoic membrane (CAM), a well-vascularized extra-embryonic tissue located underneath the eggshell, has a successful history as a biological platform for the molecular analysis of cancer including viral oncogenesis, [8] carcinogenesis, [9] tumor xenografting, [1] [10] [11 ...
In 2012 a study by Boubli, et al. demonstrated that C. imitator and C. capucinus split up to 2 million years ago. [ 5 ] [ 6 ] Boubli's study also indicated that the Honduran white-faced capuchins, which had previously been considered a to be a possible separate subspecies, C. capucinus limitaneus , was not genetically distinct from the ...
Blattodea is an order of insects that contains cockroaches and termites. [3] Formerly, termites were considered a separate order, Isoptera, but genetic and molecular evidence suggests they evolved from within the cockroach lineage, cladistically making them cockroaches as well. [4]
Recollection of spatial details is a top-down procedure that requires an individual to recall the superordinate features of a cognitive map, followed by the ordinate and subordinate features. Two spatial features are prominent in navigating a path: general layout and landmark orienting (Kahana et al., 2006).
