Doctors worried about the drug also causing hemorrhages, slowing contractions and depressing the baby's breathing.
It has been proposed that the direct effect of NO in muscle cells is to slow contraction and its associated metabolism [16].
If shortening velocity is a reasonable indicator of cross-bridge cycling, then the observed reduction in shortening velocity with time of contraction suggests that the cross-bridge cycling rate must be slowing with contraction.
Lastly, BME and MTG treatments resulted in less frequent beating, slower contraction and relaxation velocities than untreated cells.
The FN nanofibers were found to have a fast contraction regime, τ1, of 2.88 seconds and a slow contraction regime, τ2, of 157.41 seconds.
Eventually the branes would stop moving apart and hurtle toward each other again, causing a slow contraction of our universe and finally another Big Bang.
The expansion speed experienced a quick increase to maximum and then a steady decrease to zero and finally the area change was converted into a slow contraction.
The contour length as a function of time after release (green dashed line) was fit to a double exponential curve (r2 = 0.99) with a rapid contraction regime of τ1 = 2.88 sec and a slower contraction regime of τ2 = 157.41 sec.
In these scenarios, the Universe is smoothed and flattened during a period of slow contraction preceding the bounce while quantum fluctuations generate nearly scale-invariant superhorizon perturbations that seed structure in the post-bounce Universe.
Researchers have been able to promote significant regeneration in injured mouse latissmus dorsi muscles by seeding muscle stem cells onto strips of ECM from pig bladders and then mechanically "exercising" the tissue by slow contraction and expansion of the strips.
By contrast, the new results are consistent with the simplest versions of ekpyrotic cyclic models in which the Universe is smoothed and flattened during a period of slow contraction followed by a bounce, and another promising bouncing theory, anamorphic cosmology, has been proposed that can produce distinctive predictions.
