The phrase "as previously studies" is not correct in written English.
It seems to be a typographical error and should be "as previously studied."
Example: "The results of the experiment were consistent with the findings as previously studied in earlier research."
Alternatives: "as previously examined" or "as previously analyzed."
Patients with a visually apparent generally increased muscular uptake as previously studied by us were not included [11].
As previously studied, adsorption of sudan I, acid orange 7, acid red 27, acid red 112 on fibrous activated carbon in ethanol-water mixtures [35] and adsorption of malachite green on silica gel in 2-propanol-water mixtures [33] decreased with increase in organic solvent weight percentage.
This polymorphism was investigated using restriction fragment length polymorphism analysis of polymerase chain reaction products as previously studied [ 16].
Some of the mutations may render the toxin dysfunctional, leading to decay of the TA system as previously studied for the ccdO157 system.
The increased tumor latency was also opposite to MMTV-PyMT/TGFβRII-KO mice with deletion of Tgfbr2 in the mammary epithelium [ 5], as previously studied in our laboratory.
The polymorphisms (IL-1β-31 IL-1β-511 IL-1β-511 IL-1β-511ted using restriction fragment length polymorphism analysis of polymerase chain reaction products as previously studied [ 19].
As previously studied, the MFEI of most miRNA precursors was greater than 0.85, which was notably higher than other non-coding sRNAs.
The US cohort consisted of 1601 1-year survivors of RB diagnosed between 1914 and 1984 at two US hospitals, as previously studied by Kleinerman et al (2005).
As mentioned previously, studies employing cultured cells as well as patient specimens have shown that a strong correlation exists between TF expression and aggressive tumour behaviour [ 102, 103].
