The results suggest that the accumulation of C4S-, C0S-, and C6S-carrying PGs, and of BSP and OPN is a primary event at the initial PF attachment, and is involved in the adhesion of PFs and mineralization of the initial attachment layer.
However, in light that the overlap in the datasets of IL-6 versus NGF is rather small, TrkA activation may not be a primary event at all or at the time point of our study.
Temperatures of −20 °C are also the lowest at which viable catalytic reactions are possible, indicating that the reactions should be slowed to only primary events at this temperature.
Sequential exocytosis starts with a primary fusion event at the plasma membrane, and other granules subsequently fuse with this granule.
Patients with acute BRAO were examined within 36±5 h after primary event and at weekly/monthly intervals thereafter.
Compared with patients with intended invasive treatment, patients with intended non-invasive management had an initially lower primary event rate, but the event curves crossed at approximately 30 days and increased more over time (fig 3).
Recent reports have confirmed that the primary event in GA is at the level of RPE and that expression and localization of basolateral proteins such as CD63 and MCT3 diminish with the progression of RPE alteration across GA lesions, also suggesting loss of polarity in the late dry form of AMD [ 24].
Assuming that lithium's prophylactic efficacy against mood episodes were the primary event, more patients would be at risk to potentially drop out for reasons other than a mood episode (for example, due to side effects) - and consequently, this meta-analysis may be biased to the disadvantage of lithium when it comes to dropping out of the study for reasons other than a mood episode.
The first event among local, regional, and distant recurrence and death was counted as the primary event, and any ensuing events were censored at the date of the primary event.
