Because shear waves cannot propagate in vicious fluid, no signal can be measured, for example, in cysts [ 28, 29].
Speaking at a news conference, the commissioner, Richard Dormer, said that he did not want to "speculate on what drove the suspect to such a vicious, criminal act," but signaled that investigators considered addiction a likely motive.
In a vicious circle, capillary rarefaction, hypoxic signaling and tissue hypoxia may mutually reinforce each other leading to further damage and fibrosis.
In breast cancer cells, HER2 overexpression may be accompanied by an increase in cell membrane lipid raft microdomains, thereby establishing a vicious cycle of aberrant cell signaling [ 1, 15].
This sets up a "vicious cycle" whereby SCF/c-Kit signaling further stimulates the production of more MCs, which promotes metastasis.
As outlined above this may result in a vicious, self-enforcing cycle of deranged signalling and A β production driving the pathogenesis.
Inhibiting NFκB signaling might limit the vicious cycles of inflammation and oxidative stress, in part by interrupting synergistic crosstalk between these two processes.
Subsequently, dimerization of activated EGFR with other HER family receptors, particularly HER2, activates intracellular signaling pathways, which in turn may enhance nuclear ER signaling [ 4], thus completing a vicious cycle of events.
Senior officials keep missing opportunities to keep their signals straight, prompting cases of vicious backbiting that one senior member of Mr. Bush's national security staff said with disgust the other day "make us sound like Democrats".
In fact, an impairment of Cav-1 mediated internalization and degradation of VEGFR2 leads to a vicious loop, with redundant effects of VEGF signaling and consequent increased CTGF production.
The attack on Nairobi's Westgate mall is a vicious development in the war on terrorism: It signals the evolution of an unpopular splinter faction of a radical Somali group into a truly transnational terrorist organization.
