Example: "The alterations by a skilled designer transformed the entire space into a modern masterpiece."
Alternatives: "modifications made by a" or "changes implemented by a".
α7 nAChR activation ameliorated these alterations by a mechanism involving heme-oxygenase I induction.
Combined with the earlier observation that small polar organic compounds can migrate across mineral surface water films, this provides support for the hypothesis that initially water-wet mineral surfaces can undergo wettability alterations by a two-stage process, involving initially the establishment of a surfactant layer by small polar organic molecules replacing water at the mineral surface.
Several parasites are known to cause ZO-1 alterations by a wide array of mechanisms [ 33, 53, 54].
Our first formulation involves nucleotide-level alignment that can detect structural alterations by a single-unified dynamic programming approach.
The array CGH analysis data were evaluated to identify genomic alterations by a statistical analysis with Genomic Workbench Standard Edition version 5.0.14 (Agilent).
Cases where motif alteration by a SNP changes predicted splice strengths that would change the likelihood of alternative splicing (substitution of a non-standard donor or acceptor for the standard donor or acceptor, Supplementary Material, Fig. S2) are of interest.
Taking into account these previous data, the purpose of this study was focused on elucidating the historical progression of these alterations by studying a series of animals with advanced cirrhosis and ascites.
Phenotypic alteration by an organism in an imposed condition has been considered an important strategy for better adaptation [29].
Chemical alteration by an organism of a chemical compound.
"Ecosystem engineering" describes habitat alteration by an organism that affects another organism; such nontrophic interactions between organisms are a current focus in ecological research.
In this study we have characterized the molecular alterations produced by a novel frameshift PYGM mutation (p.R771PfsX33), at the mRNA and protein levels, in the skeletal muscle biopsy of two related McArdle patients.
