One of the biomarkers, mass-to-charge ratio 3025.5, was identified by high-resolution tandem mass spectrometry as zona radiata protein, fragment 2.The weak environmental estrogens MXC, BPA, and TPP elicited protein expression profiles consistent with the estrogen expression model.Estrogen-responsive mass spectral biomarker peaks were identified by comparison of E2-treated and control plasma spectra.
In this study we examine the use of a small fish and plasma protein expression for detecting estrogen agonist activity in a vertebrate model.

A small fish model and surface-enhanced laser desorption/ionization time-of-flight mass spectrometry were used to investigate plasma protein expression as a means to screen chemicals for estrogenic activity.
The focus of the chapter is to provide a cross section of progress in the area of non-acoustic sensors for underwater mobile platforms and to provide a framework for structuring the subject of oceanographic non-acoustic sensors.
State-of-the-art non-acoustic sensor systems are a summation of five areas: advanced analytical detectors, distributed computing, network technology, automation and power systems.
