( H ) TEM image of collagen fibrils ( col ) next to the epithelial cell ( e ) . In our approach we decided to use disability as a selection criterion and a descriptive rather than a normative approach to identify the reasons for it . A standard event list was used to quantify the number of traumatic event types a person had experienced ; the list included 11 types of events : active combat experience , accident , natural disaster , witness murder or killing , rape , sexual molestation , physical assault , being kidnapped or captured , torture , other , or suffered shock because a close person had experienced a traumatic event . We have identified mutations in the H-Ras proto-oncogene as a significant feature of Wnt1-induced tumorigenesis ( Table 1 ) , and we have shown that an inherited Neu transgene or an inherited deficiency of the p53 tumor suppressor gene can provide a selective advantage to Wnt1-expressing mammary cells that overrides the selective advantage conferred by somatic mutation of H-Ras .
