Understanding the mechanisms of lung mechanical stress [PDF]
Brazilian Journal of Medical and Biological Research, 2006 Physical forces affect both the function and phenotype of cells in the lung. Bronchial, alveolar, and other parenchymal cells, as well as fibroblasts and macrophages, are normally subjected to a variety of passive and active mechanical forces associated with lung inflation and vascular perfusion as a result of the dynamic nature of lung function. These

Mechanisms of stress in the brain [PDF]
Nature Neuroscience, 2015 The brain is the central organ involved in perceiving and adapting to social and physical stressors via multiple interacting mediators, from the cell surface to the cytoskeleton to epigenetic regulation and nongenomic mechanisms. A key result of stress is structural remodeling of neural architecture, which may be a sign of successful adaptation ...

Mechanism of Oxidative Stress in Neurodegeneration [PDF]
Oxidative Medicine and Cellular Longevity, 2012 Biological tissues require oxygen to meet their energetic demands. However, the consumption of oxygen also results in the generation of free radicals that may have damaging effects on cells. The brain is particularly vulnerable to the effects of reactive oxygen species due to its high demand for oxygen, and its abundance of highly peroxidisable ...

Influence of shear stress applied during flow stoppage and rest period on the mechanical properties of thixotropic suspensions [PDF]
, 2008 We study the solid mechanical properties of several thixotropic suspensions as a function of the shear stress history applied during their flow stoppage and their aging in their solid state.
