To date accumulation of the Aβ in the retina has mostly been studied in the transgenic AD murine models to investigate whether toxic Aβ in the retina may cause visual disturbances in patients with AD.
To date, accumulations of corrosion products on these same materials on shipwrecks in freshwater environments have not had an icicle shape (2014 email communication from Ley S; unreferenced).
To date, PHB accumulation has been reported for a few cyanobacterial species with photoautotrophic PHB production reaching less than 10% of dry cell weight (dcw) (Bhati et al. 2010).
To date, the accumulation of evidence literature is mostly composed of electrophysiological experiments with primates.
Although bone-specific Tregs have not been proven to exist to date, the accumulation of Tregs at sites of intense bone remodeling (i.e., the epiphysis of long bones) favors the concept that Treg cells need cell-to-cell contact and act locally on bone.
Coupled with the constraints derived from the deposit's paleoclimatic proxies, OSL dating places the accumulation of this terrace in MIS 5a, and radiocarbon dates from the overlying breccia cum alluvium (sub-complex AS1) fall in the middle part of MIS 3; the intervening hiatus relates to valley incision and attendant erosion.
This experiment provides the best evidence to date that the accumulation of random mitochondrial DNA mutations induces aging-related dysfunction, he says.
A key factor that has limited the success of this approach to date is insufficient accumulation of the engineered protein variants in vivo due to their improper folding and/or reduced stability, compared to the native protein.
The glacial phase, indicated by the expansion of herbs as well as by ephemeral streams associated with calcareous palaeosols, extends from the base of the succession and culminates close to an impressive mammalian bone accumulation dated at 1.87 Ma.
To date, in LINCL, accumulation of only subunit c has been demonstrated to be a component of autofluorescent ceroid lipofuscin [39].
