Large-scale gene expression profiling of human brain samples is limited by the frequently poor quality of preserved material, and inconsistencies between specimens in term of tissue dissection and preservation, factors which may have contributed to inconsistent or discrepant results in efforts to replicate gene expression profiling studies of neuropsychiatric phenotypes (9, 16– 16).
With a number of human cell products currently in phase 3 trials, there is a need for a more regulated, fully characterized and efficient preservation process which may entail moving away from the current "gold standard" of 10% v/v Me2SO in serum, growth medium or other solutions.
This is because it generally relies on comparisons between various structures in the fossil material (the preservation of which may be less than perfect) and extant material, a procedure that may be based on pre-suppositions that are not necessarily spelt out unequivocally.
If impossible, alcohol-inactivated autograft replantation without articulation preservation is recommended, which may results in joint surface degeneration and joint instability.
"They're second-generation kids trying to focus toward cultural preservation, reinscribing a tradition which may or may not have existed back in India".
One possible advantage of revision TAA is preservation of ankle motion, which may reduce the risk of development of OA in adjacent joints (Fuchs et al. 2003).
DEMOCRATS are on tenterhooks about the preservation of their Senate majority, which may help explain another convention phantom: gun control, the issue they feel they mustn't touch.
This hypothesis is discussed in light of potential preservation and time-averaging effects which may affect patterns visible in the fossil record.
In this light, they also studied the modifications that may happen to the file content or metadata during uploading and downloading process, which may affect preservation of evidence, on Android and iOS platforms [53].
