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
TLDR
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.
TLDR
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.
A structural model for the viscoelastic behavior of arterial walls: Continuum formulation and finite element analysis
In this paper we present a two-layer structural model suitable for predicting reliably the passive (unstimulated) time-dependent three-dimensional stress and deformation states of healthy young…
A viscoelastic model for fiber-reinforced composites at finite strains: Continuum basis, computational aspects and applications
Abstract This paper presents a viscoelastic model for the fully three-dimensional stress and deformation response of fiber-reinforced composites that experience finite strains. The composites are…
Survey of gene amplifications during prostate cancer progression by high-throughout fluorescence in situ hybridization on tissue microarrays.
TLDR
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.
GreenLight laser vaporization of the prostate: single-center experience and long-term results after 500 procedures.
TLDR
PVP is a safe and effective procedure for treatment of LUTS secondary to BPH and patients on ongoing oral anticoagulation can be safely operated on.
Modeling 3D crack propagation in unreinforced concrete using PUFEM
Abstract Concrete is a quasi-brittle material, where tensile failure involves progressive micro-cracking, debounding and other complex irreversible processes of internal damage. Strain-softening is a…
Biomechanical rupture risk assessment of abdominal aortic aneurysms: model complexity versus predictability of finite element simulations.
TLDR
PWRR reinforces PWS as a biomechanical rupture risk index and has a major impact on AAA biomechanics and rupture risk, and hence, needs to be considered in meaningful FE simulations.
Prognostic utility of the recently recommended histologic classification and revised TNM staging system of renal cell carcinoma
A new, internationally accepted histologic classification of renal cell carcinoma (RCC) and a new edition of the TNM staging system were introduced in 1997. In the latter, there was a dramatic change…
