Lydgate talked persistently when they were in his work-room, putting arguments for and against the probability of certain biological views; but he had none of those definite things to say or to show which give the waymarks of a patient uninterrupted pursuit, such as he used himself to insist on, saying that "there must be a systole and diastole in all inquiry," and that "a man's mind must be continually expanding and shrinking between the whole human horizon and the horizon of an object-glass.

An ultrasonic measurement called the renal arterial resistive index (RI) can be calculated by determining the ratio of change in renal (kidney) blood flow velocity between systole (when the heart contracts) and diastole (when the heart relaxes) to the systolic velocity.
