The theory suggests that rapid adjustment of parasites to the immune defenses of the host requires a constant modification of the host's immune system, constraining the fixation of immune quality by directional selection.
This biomaterial, which boasts optimal biocompatibility, has been the object of constant modification aimed at better adapting it to the functional needs of the host tissue.
Constant modification of the chemical structure by covert laboratories allows manufacturers to stay one step ahead of the legal process.
As annotation is ongoing and remains under constant modification, a comprehensive analysis of the potential function of the clusters with codons under selection would not lead to reliable results.
Searches were performed using monoisotopic masses with the following parameters: taxonomy, other green plants; constant modification, iodoacetamide; Partial modification, methionine oxidation; mass tolerance, 200 ppm.
He no longer insisted on the vicious circularity of the definition involved in the contradictions; instead, he held the view that a predicative classification is characterized by invariance, i.e., that it cannot be affected by the introduction of new elements; by contrast, impredicative notions are subject to constant modification whenever new elements are introduced.
Because the effectiveness of treatment and the sensitivity of screening tests change over time (which may change the natural history of both treated and untreated cancer), models would need constant modification to provide valid monitoring of overdiagnosis over time.
We show how a rationale idealising improved NGO accountability through quality improvement underwent constant modification in a context where programmes seeking to facilitate this ideal were congenitally failing and continually altered.
I had to approach my patients, not with idly open-ended questions, but through an interpretive lens that required a constant modification of my questions based on previous answers or findings.
Variable modifications selected were methionine oxidation and N-terminal acetylation; constant modification selected was S-Carbamidomethylation of cysteine residues.
