The phrase "activity was evaluated from" is correct and usable in written English.
It can be used when discussing the assessment or analysis of a particular activity, often in research or academic contexts.
Example: "The effectiveness of the training program was evaluated from the participants' feedback and performance metrics."
Alternatives: "activity was assessed based on" or "activity was analyzed using".
The catalytic activity was evaluated from steady state current vs voltage measurements for the electrochemical reduction of oxygen in 4 N H2SO4.
DICR activity was evaluated from Ca2+ release induced by high potassium in the bath solution (high [K+]o), which triggers membrane depolarization.
mTOR activity was evaluated from the phosphorylation of p70S6K1.
The locomotor and exploratory activity was evaluated from measurements of the number of line crossings and the number of rearings (the number of times the animal stood on its rear limbs).
Sirt1 activity was evaluated from cytoplasmic and nuclear compartments using a fluorometric assay (SIRT1 fluorimetric kit, BML-AK-555; Enzo Life Sciences, Villeurbanne, France) at the 15-min point.
The effects of cell suspension concentration and disruption time on volumetric activity, total protein and specific activity were evaluated from a 22 full-factorial central composite design.
Sirt1 deacetylase activity was evaluated in nuclear extracts from the liver, heart, kidney and lung of young, middle-aged, and aged rats, using the Cyclex SIRT1/Sir2 Deacetylase Flourometric Assay Kit (CycLex, Nagano, Japan).
Osteoclast activity was evaluated following a scale from 0 to 4 regarding TRAP staining, as previously described [ 23]: 0 = no staining; 1 = rare positive cells; 2 = some foci of positive cells; 3 = multiple foci; and 4 = diffuse staining.
Anti-inflammatory activity was evaluated using the methanolic extract from different parts of J. curcas.
Microsomal aromatase activity was evaluated by tritiated water release from radio-labeled substrate [1β-H]-androstenedione as previously described (Moslemi et al. 1993, 1997).
The photocatalytic activity was evaluated by the H2 liberation rate from water splitting under visible-light irradiation.
