1.   One negative control sampled was processed for every three tissue samples examined.

2.   The tissue samples are taken from the foetus at seven weeks old, when it is only about one inch long.

3.   Thus, the variable orientation and size of individual tissue samples might have affected our results.

4.   Tissue samples were assessed biochemically for the neutrophil marker enzyme, myeloperoxidase, using the method of Krawisz et al.

5.   Tissue samples were snap frozen in liquid nitrogen or on dry ice in a cryoprotective broth and stored frozen.

6.   The results of imaging investigations, surgery and histological examination of tissue samples were reviewed by reference to the patients notes.

7.   Ardais plans to build a library of tissue samples that it will make available to researchers for a fee.

8.   Ardais hopes to eventually create a massive tissue catalog, allowing researchers to place Internet orders for tissue samples from patients with the specific diseases they are studying.

9.   At Johns Hopkins, Dr. Gary R. Pasternak, director of the division of molecular pathology, and his team studied tissue samples from men with prostate cancer.

10.   Blood and tissue samples show that the man died from infection with Clostridium sordellii, a rare bacterium found in human intestines and in soil.
