On stiffer substrates (>60 kPa) approximating the damaged heart, myocytes form stress fiber-like filament bundles but lack organized sarcomeres or an elongated shape.
Using elastic governing equations and a weak form stress boundary condition, a closed-form solution of elastic fields in the weak layer is derived and the energy release rate for opening-mode fracture is obtained.
α-SMA is widely expressed in both SMCs and MFBs [13] and regulates cell contractility when it is incorporated within actin filaments to form stress fibers.
We observed that strains lacking Lsm12 and Pbp4 were still able to form stress granules and P-bodies, although the stress granules formed at slightly reduced levels compared to wild-type (Figure 3).
Taken together with our prior work [9], our results suggest that HVT MV results in phosphorylation of p38 MAP kinase, activation of MK2, and phosphorylation of HSP25, a process that causes actin to disassociate from HSP25 and polymerize to form stress fibers, which ultimately leads to paracellular gaps and increased vascular permeability.
In addition, our laboratory has previously shown that MAP kinase activated protein kinase 2 (MK2, immediately downstream of p38 MAP kinase) leads, when activated, to heat shock protein 27 (HSphosphorylationandon and subsequent reorganization of the actin cytoskeleton to form stress fibers [9].

Mr. Rosen, who said the Philharmonic would continue to experiment with the form, stressed that it was too early to judge the screens definitively.
At small deformations including stage III, the dislocation densities and the internal stresses were uniform within the grain interior, but larger near the grain boundaries where the dislocations showed a tendency to form stress-intensive arrangements.
The best evidence for such a function is that CRT may form stress-induced, i.e. heat-shock-induced, protein complexes in tobacco leaves, suggesting that it may bind to unfolded proteins and therefore possibly function as a molecular chaperone [13].
The consent form stressed confidentiality and respondents' names were never recorded.
The wording of the written informed consent (WIC) form stressed the possibility of dropping out of the study at any time if desired.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
