The phrase "action was observed for" is correct and usable in written English.
It can be used in contexts where you are describing a situation or event where a specific action took place over a period of time.
Example: "During the experiment, action was observed for several hours, indicating a significant response to the treatment."
Alternatives: "activity was noted for" or "behavior was recorded for".
Similar screening effects of protamine action were observed for 20 mM Mg++ ions as shown in Fig. 9 (triangles).
Different modes of actions are observed for melittin, tachyplesin I, d-magainin 2, MSI-843, and a synthetic antibacterial oligomer, demonstrating that SFG is very effective in the study of AMPs and AMP lipid bilayer interactions.
In the early lifting trials, an association between perception and action was observed: higher grip force was observed for the perceptually heavier object.
Chemotactic response of Tetrahymena was more sensible than proliferation as significant chemorepellent action was observed in the environmentally realistic concentration range for acetylsalicylic acid, diclofenac, fenoprofen, paracetamol, metoprolol, propranolol, timolol and trimethoprim (Chemotaxis Index ranged from 63% to 88%).
Recently, an irregular chaotic movement of the action potential of the membrane was observed for a number of techniques of control with the objective to stabilize the variation of this potential.
Preclinical evidence suggested that mAb and TKI against EGFR might not have a completely overlapping mechanism of action and synergistic actions had been observed for administering cetuximab and gefitinib simultaneously in human xenograft models (Matar et al, 2004).
Because our cells were often quiescent for long durations, determining when to terminate a recording was a challenge when no action currents were observed for long periods of time.
29 This specificity of action has been observed for the CB1 receptor whereby the antagonist WIN-55,212-2 activatedifferentnt Gi/0 subtypes with differing sensitivities 25, 26, 30, 31 (Table 2).
To do this, we added 10-15 mM KCl to the bath whenever no action currents were observed for more than 30 minutes to induce firing (Fig. 4, see legend).
