A New Constitutive Framework for Arterial Wall Mechanics and a Comparative Study of Material Models
In this paper we develop a new constitutive law for the description of the (passive) mechanical response of arterial tissue. The artery is modeled as a thick-walled nonlinearly elastic circular…
Hyperelastic modelling of arterial layers with distributed collagen fibre orientations
A structural continuum framework that is able to represent the dispersion of the collagen fibre orientation is developed and allows the development of a new hyperelastic free-energy function that is particularly suited for representing the anisotropic elastic properties of adventitial and intimal layers of arterial walls.
Metastatic patterns of prostate cancer: an autopsy study of 1,589 patients.
It is shown that bone, lung, and liver are the most frequent sites of distant prostate cancer metastases and there are strong arguments for the existence and clinical significance of a backward venous spread to the spine, which is likely to occur early in the metastatic process.

Survey of gene amplifications during prostate cancer progression by high-throughout fluorescence in situ hybridization on tissue microarrays.
FISH to tissue microarray sections enables high-throughput analysis of genetic alterations contributing to cancer development and progression and implicate a role for amplification of androgen receptor in hormonal therapy failure and that of MYC in the metastatic progression of human prostate cancer.

The present study investigates the dissection properties of the media of 15 human abdominal aortas by means of direct tension tests and peeling tests, finding that peeling in the axial direction of the aorta generates a remarkably "rougher" dissection surface with respect to the surface generated by peaking in the circumferential direction.
