The phrase "alteration group" is correct and usable in written English.
It can be used in contexts related to mathematics, particularly in group theory, where it refers to a specific type of group associated with permutations or transformations.
Example: "In the study of symmetry, the alteration group plays a crucial role in understanding the properties of geometric figures."
Alternatives: "permutation group" or "transformation group".
Therefore, if micromechanical modeling is to be deployed as a feasible method to predict the strength of Rotokawa Andesite reservoir rocks, the samples/cores should be grouped by their alteration, and KIC measured for each alteration group.
Following our own system for detecting genetic alterations in formalin-fixed paraffin-embedded by FISH, we distinguished cells without any gene alterations (group 1), cells with any possible genetic alteration (group 2) and cells with cutting artefacts (group 3), including nuclear fragments generated from sectioning of the nuclei (Piqueras et al, 2009).
In vermal-medulloblastoma subgroups at 5 6 weeks after surgery, without treatments, Riva and Giorgi [ 101] showed the following Z-scores for perseverations-WCST (speech-problem group = 0.5, language-problem group = 2.8, behavioral alteration group = 1.3 and one patient autistic-like = 2.4).
The overall CDH1 germline mutation frequency was significantly higher in group A as well as the rate of non-missense alterations (group A vs. group B: Fisher exact test χ2 15,872; p < 0.001).
After cell cycle analysis (Fig. 2e), it was found that both of labeled and unlabeled PDB-MSCs displayed the highest percentage in G0/G1 phase without significant alteration (labeled group 74.67 %, unlabeled group 76.33 %).
Light and electron microscopic studies revealed structural alterations in group (B) in the form of disturbance of villus and crypt architecture.
To distinguish hypoxia from pressure-induced alterations, a group of rats underwent banding of the pulmonary trunk (PTB), sham operation, or the rats were exposed to normoxia or chronic, hypobaric hypoxia.
However, PTHLH expression did not differ significantly between the negative and positive VHL alteration tumor groups (Table 2).
AXIN2, which cooperates with APC and β-catenin in Wnt signaling, had more methylation alterations in Group 2, and its expression levels negatively correlated with methylation determined by bisulfite sequencing.
Although investigation of the molecular consequences of chromosome alterations in group 1 retinoblastomas provides clues about pathways which are aberrantly regulated in tumorigenesis, it is also important to identify the primary mitogenic signal(s).
In summary, much has been learned about brain anatomy in dyslexia, but two main questions remain under debate: why are more significant alterations identified in studies with smaller samples than in studies with larger samples or in meta-analytical studies, and why are correlational analyses more efficient in identifying anatomical alterations than group analyses?
