35.   The researchers are testing this theory.

36.   The researchers tested it with the same sort of rat tests, with the same results, Collier said.

37.   The researchers tested resveratrol on human neural cells in laboratory cultures and found that it made them grow small extensions through which they could connect with neighboring cells.

38.   The researchers have so far tested the device on a small group of deaf and deaf-blind subjects.

39.   The researchers have tested the therapy on three patients, with apparent success in all of them.

40.   The researchers have tested this technique in the laboratory on chunks of cartilage and on whole joints taken from animals.
