Oral polio vaccine (OPV) is an attenuated vaccine, produced by the passage of the virus through non-human cells at a sub-physiological temperature, which produces spontaneous mutations in the viral genome. Oral polio vaccines were developed by several groups, one of which was led by Albert Sabin.
What is the OAT? The Optometry Admission Test (OAT) is a standardized examination. It is designed to measure the academic ability and comprehension of scientific information. The OAT is sponsored by the Association of Schools and Colleges of Optometry (ASCO) for applicants seeking admission to an optometry program.
Otoacoustic emissions (OAE) testing is often used to check newborns for hearing problems. In this test, a small, soft microphone is placed in the baby's ear canal. Sound is then sent through a small flexible probe that has been put in the baby's ear. The microphone detects the inner ear's response to the sound.
