Sentence examples for variation of circulating from inspiring English sources

The animals were monitored regularly to ensure that they were not stressed thus limiting variation of circulating hormone levels [ 11].

Although 2 main HMPV types are recognized (A and B) (1, 3, 7 ), each with 2 subtypes (A1, A2; B2, B2) (8 ), the extent of genetic variation of circulating HMPV subtypes over time has not been extensively examined.
