Alireza Karimi, Reza Razaghi
The mechanical functions of the lungs are concerned with ventilating the alveoli and aiding venous return to the heart. The mechanical properties of the lung allow this to be fulfilled with a very small expenditure of energy. Smoking via chronic obstructive pulmonary disease (COPD) can affect this mechanical function through the alteration of the mechanical properties of the lung tissue. So far, no study has been conducted to experimentally compare the in vitro mechanical properties of the human lung tissue among the healthy nonsmokers and unhealthy smokers...

Lixin Sun, Yingfei Sun, Zhipei Huang, Jiateng Hou, Jiankang Wu
BACKGROUND: Hill-type musculotendon models are most commonly used in biomechanical simulations for their computational efficacy and efficiency. But these models are generally built for maximally-activated muscles and linearly scale muscle properties when applied to submaximal conditions. However, the precondition of this scaling, which is muscle activation and properties are independent each other, has been proven unreal in many studies. Actually, the maximal activation condition is not ubiquitous for muscles in vivo, so it is necessary to adapt the linear scaling approach to improve the model practicability...
