The phrase "firstly found that" is correct and is commonly used in written English.
It is typically used to introduce the results of a study or research. For example: "The study firstly found that the majority of participants had experienced an overall improvement in their symptoms."
We, firstly, found that standards are a driving force of technological convergence.
It was firstly found that the Rieke Ni generated in situ was able to promote the pinacol coupling of various carbonyls efficiently.
We firstly found that in the Sr0.5O monolayer case, care must be taken for the LaAlO3 starting sequence in order to expect good band offsets with silicon.
We firstly found that the proliferation profiles of fibroblasts from different patients cultured within collagen gels (3D) differed significantly from their behavior observed on tissue culture plastic (2D).
Moreover, we firstly found that a Runt-related transcription factor 2 (Runx2), Satb2 and miR-31 regulatory loop triggered by bone morphogenetic protein-2 (BMP-2) plays an important role in ASCs' osteogenic differentiation and bone regeneration.
We firstly found that only basal and HER2 positive breast cancer present higher HIF-1α expression either according to HU subtype or PAM50 subtype among six distinct groups, namely, basal, HER2 positive, luminal A, luminal B, normal-like, and non-classified breast cancer, by using GOBO online analysis (co.bmc.lu.se/gobo) (p < 0.00001, Fig. 1a upper row).
Firstly, in adult rats we found that UCP3 content is higher in subsarcolemmal mitochondria, that are more prone to ROS damage, due to their lower proton leak.
Firstly, new fossils are often found that are considerably older than the previously known oldest fossil of a particular taxon, and it is thus impossible to be certain whether the oldest fossil of a particular taxon has indeed been found.
With the caveat that we studied non-polarised cells, wt-CFTR may also need to be 'active' because firstly, we find that elevating cAMP suppresses inflammatory markers by about 25% and secondly, that treatment with a specific inhibitor of channel function (CFTRinh172) [17], resulted in an increase in NF-κB activity only when wt-CFTR was present (figure 3A).
Firstly, we find that length of incubation time during energization is important.
Firstly, we find that KRI-1 is required for CED-3-dependent apoptosis induced by RNAi against dlc-1.
