A Method for Isolation and Partial Purification of Trichinella spiralis Nurse Cells Open
Invasion of vertebrate muscle cells by larvae of Trichinella spiralis is accompanied by redifferentiation of the host myofiber into a novel structure called the nurse cell. The nurse cell protects and nurtures the enclosed parasite during …

A Report of Acoustic Admittance Parameters in Normal Ears Open
The acoustic measurement of middle ear function is presently accomplished with electroacoustic instruments which measure the difference in flow of acoustic energy through the middle ear as a function of variable air pressure gradient acros…

The Role of the Middle Ear in Acoustic Trauma from Impulses Open
The purpose of this experiment was to evaluate the role of the middle ear in acoustic trauma following high-level impulse noise exposure. Eleven monaural chinchillas were exposed to either 161- or 166-dB peak SPL impulses of 1-msec “A” dur…

Some Effects of Experience on the Threshold of Audibility Open
The question whether the measured threshold of audibility improves with experience has widespread implications. It refers to the nature of the threshold itself, but it also affects the psychophysical experiments involving comparisons of th…
