The phrase "alterations were investigated" is correct and usable in written English.
It can be used in contexts where changes or modifications to something have been examined or analyzed.
Example: "After the initial results, the researchers concluded that the alterations were investigated thoroughly to ensure accuracy."
Alternatives: "changes were examined" or "modifications were analyzed."
Age-related alterations were investigated in neonate and young adult rats.
Furthermore subcellular epithelial alterations were investigated to confirm the impairment of intestinal barrier function found upon mesenteric IR.
ZFP57 sequence alterations were investigated by direct sequencing of two PCR amplification products, which included exon 1 (49 bp) and exons 2 6 (4.8 kb), respectively.
Gene expression profiles were analyzed using serial analysis of gene expression, DNA methylation profiles by methylation-specific digital karyotyping, whereas genetic alterations were investigated using SNP arrays and fluorescence in situ hybridization.
Alterations in protein secretion, intracellular signaling, and cell morphology were monitored; and the role of integrin signaling in MSeA-induced morphological alterations was investigated using divalent cation treatments.
In this study [ 9], the prognostic significance of overall genomic alterations was investigated in a cohort of 493 primary neuroblastomas by bacterial artificial chromosome array-CGH.
In contrast to the many ongoing studies using mostly biochemical modulations, the specific impact of p53 gene alterations was investigated in a limited number of studies with respect to the general impact on intrinsic cell death induction [ 5, 7, 10- 12].
In this regard, the effects of sulfate ion types (i.e. Na2SO4, MgSO4 and CaSO4) and their concentrations (i.e. 0 45,000 ppm) on wettability alteration are investigated using contact angle (CA) measurement technique.
In the case of SAMs of 3 the nature of this alteration was investigated via scanning tunnelling microscopy and found to presumably be caused by an order-disorder-transition.
