The phrase "additionally we also observed" is correct and usable in written English.
It can be used when you want to introduce an extra observation or finding that complements previous information.
Example: "In our study, we found that the treatment was effective; additionally, we also observed a significant reduction in side effects."
Alternatives: "furthermore, we noted" or "in addition, we saw".
Additionally, we also observed that the XPA mutant NSCs had impaired abilities of clonal expansion and migration even in absence of UV radiation (Fig. 4F and 4G).
Additionally, we also observed a decrease in expression of Rv3616c (EspA) in intracellular H37Ra compared to H37Rv by qRT-PCR analysis (Figure 4A).
Additionally, we also observed evidence of mammary duct differentiation at the periphery of MDA-MB-435 tumors (Figure 4A, H&E panel).
Additionally, we also observed that a long-term ingestion of CS significantly elevated liver cholesterol concentration (P<0.01), even though there is no significant difference in body weight gain and feed intake between the two groups.
Additionally, we also observed that there existed a few number of edges with high Ebc, but linking two R4 peripheral non-hub nodes such as the edge between the inferior frontal gyrus (opercular) and superior frontal gyrus (medial orbital) (Table 3).
Additionally, we also observed phenotypic HSCs identified by the combination EPCR+CD48−CD45+CD150+.
Additionally, we also observe 1p deletion at the secondary levels of stage 4 trees.
Additionally, although we also observed bronchiolocentric fibrosis in 3 CPFE patients, this finding was neither diffuse nor prominent.
Additionally, within the low latitudinal band, we also observed a longitudinal gradient in species richness, with higher species richness in eastern Asia.
Additionally, at convergence in PSI-BLAST searches of the non-redundant/NR database, we also observed hits to GGDEF domains from different signaling proteins with marginal e-values.
Additionally, as hypophosphosrylation of Akt modulates the regulation of FOXO transcription factors [27], [28], we also observed that FOXO1 is upregulated in presence of p19 (Figure 4D).
