...ow that under very strong shaking the soil may not behave in a linear fashion," said Archuleta, "so we used nonlinear soil dynamics computer models to calculate the surface ground motions created by fault ruptures."

...nutrients, they grew but did not differentiate and behave as breast cells do in the body. But when they were embedded in a 3-D extracellular matrix that mimicked real, living tissues, then the cells came together and organized as they would in the body, making tissue-like structures.

The beauty of the plan, the investigators say, is that pharmaceutical companies have already developed hundreds of different drugs that inhibit tyrosine kinases, so they can quickly move these age...Expression of Rb2/p130 and VEGF could serve as potential liver cancer prognosticators
