Measurements of photosystem-II quantum yield using these nine single-celled microalgae as biomaterial corroborated previous studies which have shown that the ToxY-PAM dual-channel yield analyser is a highly sensitive method for the detection of PS-II impacting herbicides.
This corroborated previous studies that had established roles for wnt5 and wnt11 in regulating convergence and extension movements [20], [21], and wnt11 and wnt11r in midline convergence of organ primordia [18].
Taken together, these observations showed for the first time that exposure to Tgfβ resulted in an antiproliferative response of progenitor cells in hippocampal cultures and corroborated earlier studies of cortical progenitors.
Mortality patterns within this cohort corroborated other studies showing excesses of liver cancer [ 21] and intestinal cancer [ 5, 11] among PCB-exposed workers, but this study did not show that these excesses were related to duration of employment.
This is consistent with the observation that rapamycin did not induce apoptosis in MRC-5 cells even after extended exposure (unpublished observations), and corroborated recent studies showing the anti-apoptotic properties of rapamycin [ 16, 17].
It is further corroborated by field studies showing that when almost all houses are covered, resistance evolves over a period of several years (Penilla et al. 2007; Mathias et al. 2011), which is considerably more slowly than predicted for high effective coverage (Koella et al. 2009b).
Laboratory experiments corroborated field data with the most solid-phase partitioning occurring in the waters with the highest pH.
This interpretation is further corroborated by previous studies that show this transient "stress response" to anaerobiosis is absent in catabolite-repressed (glucose) cells [ 5].
The argument has been largely conceptual, which means it could be further corroborated with empirical study.
