...targeting specific parts of the molecule for mutation and observing the results, Arnout and other researchers were able to pinpoint the position of the neutrophil receptor sites. They also found the key amino acid sequences which determine the neutrophil receptor structure...
This year is not shaping up any better. In Corpus Christi, Texas, last month, arsonists burned from one of the city's abortion clinics, along with four neighboring businesses in the same building.
