RATIONALE Mechanisms underlying diastolic dysfunction need to be better understood. OBJECTIVE To study the role of titin in diastolic dysfunction using a mouse model of experimental heart failure induced by transverse aortic constriction. METHODS AND RESULTS Eight weeks after transverse aortic constriction surgery, mice were divided into heart failure (HF) and congestive heart failure (CHF)...
This paper proposed a stiffness analysis method for a 3-PRS mechanism for welding thick aluminum plate using FSW technology. In the molding process, elastic deformation of lead-screws and links are taken into account. This method is based on the virtual work principle. Through a survey of the commonly used stiffness performance indices, the minimum and maximum eigenvalues of the stiffness matri...
Liver fibrosis, the response to chronic liver injury, results from the activation of mesenchymal cells to fibrogenic myofibroblasts. We have recently shown that two key myofibroblast precursor populations, hepatic stellate cells and portal fibroblasts, undergo activation in culture in response to increasing substrate stiffness. We therefore hypothesized that alterations in liver stiffness prece...
