Furthermore, such studies do not evaluate the generality of such processes because numerous studies failed to detect higher mutation or parasite loads in asexuals or prove comparable evolutionary plasticity to related sexual populations [[ 5- 8], rev. in [ 9, 10]].
Because such studies are difficult to perform, we did not plan to specifically compare the two proportional modes but simply to see whether the two offered the same feasibility.
Responsiveness of genes to perturbations is a dynamic property that was never studied systematically because such studies require the analysis of expression profiles of cells responding to a large variety of disturbances, and such databases did not exist before.
However, caution is required with such comparisons because many studies did not accurately explain the compliance criteria they used.
Because these studies did not control for indirect effects such as having health insurance or a regular physician.
Another limitation is that we could not distinguish between individual emotions, because most studies did not report adequately detailed data to permit such comparisons.
Because most studies do not take such natural reductions into account, they might actually underestimate the extent of recontamination in the household environment, or miss it altogether.
But few such studies are done, primarily because of an NRA-inspired bit of legislation that in 1996 stripped the CDC, the obvious federal agency to explore the public health aspects of gun violence, of the ability to conduct any research that would "advocate or promote gun control".
There were no secondary outcome measures (such as side effects of drugs) simply because the study did not involve a new drug or a new regimen.
The real impact on Mediterranean ecosystems, which are considered a hotspot of biodiversity, could be worse because the study did not look at other human impacts, such as forests being turned over to grow food.
