The vestibulo-ocular reflex also may be underactive, so that for a given head movement the eyes do not deviate sufficiently within the orbit and the observed object does not remain stationary upon the retina.
In the barrel-stave model (C and D ), TM1 swings away from the pore center but TM2 remains stationary upon channel activation, generating an open pore lined by both TM1 and TM2 and the helices are more parallel to the membrane normal than the membrane plane.
A rigorous multicomponent isotherm for preparative immobilized metal affinity chromatography (IMAC) must consider the multipointed nature of adsorption, the possibility of steric hindrance of the stationary phase upon binding of macromolecules, and the role of the mobile-phase modifier.
It was also another major accident for the Marussia F1 team; previously, in 2012, at the FIA-approved Duxford Aerodrome testing facility, reserve driver Maria De Villota suffered major head injuries after colliding with a stationary truck, upon returning to the service area from straight-line testing.
The results confirmed that the RhoA activity decreased in both the migrating and the stationary cells upon EGF, at a slower rate in migrating cells than that in stationary cells (Figure 5).
In contrast to the polarized RhoA activity in migrating cells, the global down-regulation of the RhoA activity in stationary cells upon EGF stimulation may promote the protrusion in all directions without discrimination, which prevents a persistent and directional migration.
The switch from primary metabolism (exponential growth) to secondary metabolism (stationary growth) upon nutrient starvation is commonly found in most microorganisms [ 1].
One could expect that processes that are directly or indirectly connected to the entrance and exit of stationary phase upon depletion and re-addition of an essential nutrient may be good candidates (Gray et al., 2004).
We expressed a variant of channelrhodopsin, ChETA, in VIP neurons of binocular V1 by infecting VIP-Cre mice with AAV-DIO-ChETA-YFP; we had previously shown this treatment to enhance visual responses of excitatory cells in stationary mice upon stimulation with blue light (Fu et al., 2014).
In this respect D-xylonate producing cells resemble cells with constitutive PKA pathway activation, which do not adapt to stationary phase upon nutrient deprivation, show low level of storage carbohydrates, are highly sensitive to heat shock and grow poorly on non-fermentable and weakly fermentable carbon sources [ 51, 52].
Then the camera pans to James Delos Peter Mullann)—whose company owns the park pedaling a stationary bike before setting upon his morning rituals.
