The phrase "activity which is used" is correct and usable in written English.
It can be used when describing a specific action or task that is employed for a particular purpose or in a certain context.
Example: "The activity which is used to enhance team collaboration is essential for project success."
Alternatives: "task that is utilized" or "action that is employed".
This may reflect the fact that, unlike the spinal cord and telencephalon, the ventral midbrain has a strong endogenous Wnt signalling activity, which is used for ventral patterning [12], [37].
The system does not depend on the brain's normal pathways of peripheral nerves and muscles but relies on signal acquisition technology to capture the signal generated from brain activity, which is used to control external equipment after analysis and processing.
Another important feature is the depth variance associated with the temporal activity, which was used by Ferreira et al. in [11] for temporal segmentation of 3D video.
The outputs produced by the MTT algorithm included the burned pixels as well as metrics of crown fire activity, which were used as a proxy measure of burn severity (low, medium, and high).
The as-prepared Fe3O4 microspheres exhibited porous structure, large surface area, strong superparamagnetic characters, as well as peroxidase-like activity, which are used as efficient enzyme mimetics to degrade organic pollutants (methylene blue).
P-gp ATPase activity, which was used to evaluate the affinity of substrates to P-gp, was stimulated by emodin and DAG with Km and Vmax values of 48.61, 29.09 μM and 71.29, 38.45 nmol/min/mg protein, respectively.
The PET scans were assessed visually and judged positive in case of detection of focally increased uptake above the surrounding tissue or increased uptake as compared to mediastinal blood pool activity which was used as region of reference in terms of FDG accumulation.
The selected RA sera with pronounced inhibitory activity, which were used in the preincubation experiments, were also used for experiments determining the heat resistance of the inhibitory activity.
100 μl Tropix Accelerator (Applied Biosystems) was then automatically injected and measured to quantify β-galactosidase activity, which was used to normalize luciferase activity values.
The intensity of the luciferase activity in these cells was normalised against the β-galactosidase activity, which was used as an internal control.
There are earlier indicators of hepatocarcinogenic potential which include increased liver weight, evidence of cytotoxicity, enzyme induction and CAR agonist activity which are used to aid dose setting for long term bioassays and in estimating risk.
