Intensity-dependent effects of microwave electromagnetic fields on acetylcholinesterase activity and protein conformation in frog skeletal muscles.

Background: This study was conducted to investigate the effects of continuous microwaves (2.45 GHz) of different field intensity on acetylcholinesterase activity and protein conformation in muscle fractions from frog skeletal muscles.

Materials/methods: [corrected] Acetylcholinesterase activity in samples from muscle homogenate fractions exposed for 30 min to microwaves of low (10 mW/cm2) or high (20 mW/cm2) intensity at almost constant temperature (1.
