Thus, rAAV2 vectors readily infected the lungs of rats, and transgene expression occurs long-term.
Implant-related infection is intractable, and, once it occurs, long-term treatment may be necessary, including several surgeries; implant removal is also inevitable in some cases [ 1, 2].
Given this pattern of naturally occurring, long-term variability in precipitation, say the scientists who performed the study, there is a "very high probability" that a devastating dry period, possibly lasting decades, will visit tropical Africa again in the next 50 to 100 years.
Because delayed dedifferentiation can occur, long-term surveillance of the operative site is recommended.
The risks and complications related to implant therapy are divided into those that occur during surgery (such as excessive bleeding or nerve injury), those that occur in the first six months (such as infection and failure to osseointegrate) and those that occur long-term (such as peri-implantitis and mechanical failures).
In contrast, our study was conducted on naturally occurring, long-term and recurrent infections.
The most frequently occurring long-term complications are chronic pain (up to 50%) and reduced shoulder function (reported at 35%).
A 'frame shift' in the priorities of the individual patient may occur during long term studies.
Positive selection under site models cannot identify particular branches where positive selection has occurred, but they can detect positive selection among sites where it occurs as long-term trends or among multiple branches separated on the tree.
Moreover, although deaths occurring in the long term due to complications have been well described [ 2, 3], deaths occurring in the acute phase have been little analyzed.
Such advances will doubtless occur in the long term.
