Matrix stiffness, endothelial dysfunction and atherosclerosis

Molecular Biology Reports, 2022
Abstract Background Atherosclerosis (AS) is the leading cause of the human cardiovascular disease (CVDs). Endothelial dysfunction promotes the monocytes infiltration and inflammation that participate fundamentally in atherogenesis. Endothelial cells (EC) have been recognized as mechanosensitive cells and have different responses to distinct ...

EFNA2 Mediates Stiffness-Regulated Hypopharyngeal Cancer Progression [PDF]

Clinical and Experimental Otorhinolaryngology
Objectives Hypopharyngeal cancer (HPC), originating from the hypopharyngeal mucosa, is associated with a poor prognosis. Extracellular matrix (ECM) stiffness is closely linked to tumor progression and patient outcomes. This study aimed to investigate the

Tumor matrix stiffness provides fertile soil for cancer stem cells

Cancer Cell International, 2023
Matrix stiffness is a mechanical characteristic of the extracellular matrix (ECM) that increases from the tumor core to the tumor periphery in a gradient pattern in a variety of solid tumors and can promote proliferation, invasion, metastasis, drug ...

Joint Stiffness Identification of a Heavy Kuka Robot with a Low-cost Clamped End-effector Procedure [PDF]

, 2014
This paper proposes two new methods for the identification of static stiffnesses of multi degrees of freedom heavy industrial robots. They are based on a locked link joint procedure obtained with an end-effector fixed to the environment. The first method

Effect of matrix stiffness on osteoblast functionalization [PDF]

Cell Proliferation, 2017
AbstractObjectivesStiffness of bone tissue differs response to its physiological or pathological status, such as osteoporosis or osteosclerosis. Consequently, the function of cells residing in bone tissue including osteoblasts (OBs), osteoclasts and osteocytes will be affected.

Matrix Stiffness and Colorectal Cancer.

OncoTargets and therapy, 2020
In recent years, a growing consensus is emerging that the mechanical microenvironment of tumors is far more critical in the onset of tumor, tumor progression, invasion, and metastasis. Matrix stiffness, one of the sources of mechanical stimulation, affects tumor cells as well as non-tumor cells in multiple different molecular signaling pathways in ...

Behavior and failure tracking of structural elements using applied element method

Przegląd Naukowy Inżynieria i Kształtowanie Środowiska, 2022
Applied element method (AEM) is a recently displacement-based structural analysis method. It provides the benefits of both the finite element method (FEM) and the discrete element method (DEM).
