The group A streptococci produce a variety of so-called virulence factors that permit them to evade the defense mechanisms of the host and thus cause disease.
The shortest peptide-sized PB2 construct (amino acids 1 33) was soluble; its short length may permit it to evade host proteases whilst it contains no hydrophobic core [43].
The genetic diversity of this carriage population permits it to evade host surveillance systems, retain or evolve resistance to antimicrobial agents, and adapt rapidly to new hosts (see Levin et al. [8]).
Strains from both hMPV groups cocirculated in South Africa (Soweto, Johannesburg), but not all 4 subgroup viruses cocirculated in a single year, evidence for a complex circulation pattern that permits hMPV to evade preexisting immunity.
Promoter hypermethylation of Twist may permit cells to evade apoptosis and has been found to be a feature of both in situ and invasive breast cancer, particularly of the ductal rather than the lobular subtype [ 10, 22].
Virulence factors are the most important proteins in pathogens, such as toxin synthetic enzymes and secreted biodegradation enzymes (2), that permit them to evade the defense mechanisms of the host and, thus, cause diseases (3).
And, crucially, they have been permitted to raise fees often in a disguised form to evade nominal government-imposed limits.
The most valuable privately held company in the United States at the moment is currently under federal investigation for potentially violating the Foreign Corrupt Practices Act; for developing software to spy on drivers for competing ride-sharing services; and for using software to allow its drivers to evade law enforcement in jurisdictions where it was not permitted to operate.
Swift's decision is a turnabout from a month ago, when advocates of stronger sanctions in the United States were publicly pressuring it to expel Iranian banks, arguing that Swift was legally required to act in order to close a loophole that permitted sanctioned banks to evade penalty.
The cancer lineage has not merely evaded the immune system, but is actually recognized as a co-aligned entity, and is permitted to share in ecological resources.
