The resulting depolarization supports autoregenerative activation which, albeit concerning a small fraction of total channels, may substantially distort membrane potential course (early afterdepolarizations, EADs) and even trigger propagated activity [ 2, 3].
It concerns, however, a small fraction of the total number of AF patients, roughly 6% of individuals under 65.
We deleted MFα1 because of a concern that a small fraction of cells could switch from MATa to MATα and then synthesize α-factor; MFα1 is the major source of α-factor in MATα cells [10].
In addition, costly antidoping efforts in elite competitive sports concern only a small fraction of the population.
This achievement is now realistic, although it concerns a small only fraction of cases.
That said, the megatrends remain concerning; while drug costs represent only a small fraction of the overall healthcare equation, they are likely to remain (like other healthcare costs) under intense pressure, and it will be increasing important to demonstrate that the benefits of innovative new products justify their high costs.
And after tax reform (which I'm concerned will not occur within my lifetime), any cost will likely be only a small fraction of the actual foreign taxes paid.
Yet due to high construction and operating costs, as well as environmental concerns, we're not likely to see reclaimed seawater represent more than a small fraction of America's clean water reserves for some time to come.
If the oil concern is forced into liquidation, a fire sale of its assets would probably provide only a small fraction of the $3.6 billion it owes bondholders.
Although SSRs represent only a small fraction of the genes (0.2% of the coding sites), they cannot be disregarded as far as mutability is concerned.
