The phrase "alter approximately" is not correct and does not convey a clear meaning in written English.
It is unclear when to use it, as the combination of "alter" and "approximately" does not logically fit together in standard usage.
Example: "We need to alter approximately the design to fit the new specifications." (This example is awkward and unclear.)
Alternatives: "modify roughly" or "change about".
The nesosilicate structure is altered, and approximately 20% of the SiO4 tetrahedra formed Si-O-Si bridging in this region.
Her2 and p53, the most widely evaluated cancer-related genes, are only altered in approximately 20-25 % of breast carcinomas, primarily in ER/PR negative tumors [ 22].
The transformation related protein p53 gene, Trp53, is the most frequently mutated gene in human cancer, altered in approximately 50% of human malignancies (Brosh and Rotter, 2009).
It is altered in approximately 20 30% of breast carcinomas and this is manifested as gene amplification and/or protein overexpression [ 3- 5].
There are data which suggest that lipid metabolism in TS cohorts is altered, with approximately 50% of TS patients over 21 years displaying hypercholesterolemia [24].
Baf155 and Baf250a have recently been associated with a loss of tumor suppressor activity in human cancer cell lines [77] and gynecologic cancers [78], whereas ARID1A, the gene encoding the Baf250a subunit, has been found to be altered in approximately 10% of breast carcinomas [79].
However, the use of this task restricted our analysis to the latency range prior to the earliest articulatory movements that would alter MEG recording, (approximately up to about 300 ms).
The cDNA-AFLP analysis shows that 30 h of moderate heat stress (MHS) alter the expression of approximately 1% of the studied transcript-derived fragments in a heat-sensitive genotype.
However, mutational analysis reveals that the p53 gene is altered in only approximately 11% of melanomas (Hussein, 2004).
This study has shown that the guideline for preoperative MRI scanning in lobular cancer will alter the surgical management in approximately 20% of patients.
