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 ...

Mechanical influence of tissue scaffolding design with different geometries using finite element study [PDF]

, 2023
The mechanical properties of tissue scaffolds are essential in providing stability for tissue repair and growth. Thus, the ability of scaffolds to withstand specific loads is crucial for scaffold design.

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

Interaction of Mechanical Heterogeneity and Residual Stress on Mechanical Field at Crack Tips in DMWJs

Science and Technology of Nuclear Installations, 2022
The interaction between the mechanical heterogeneity and the residual stress in dissimilar metal welded joints (DMWJs) leads to a complex mechanical field of crack tips, which strongly affects stress corrosion cracking (SCC) behaviors.

Effects of Mechanical Stress Stimulation on Function and Expression Mechanism of Osteoblasts

Frontiers in Bioengineering and Biotechnology, 2022
Osteoclasts and osteoblasts play a major role in bone tissue homeostasis. The homeostasis and integrity of bone tissue are maintained by ensuring a balance between osteoclastic and osteogenic activities.

Regular Mechanical Stimuli Enhanced Tolerance to Salinity Stress in Glycine max L. Seedlings

Journal of Tropical Life Science, 2023
Regular touch treatment leads to plant adaptations that enhances mechanical strength. In many crop plants these adaptations result in cross-tolerance to biotic stress caused by bacterial or fungal infection and abiotic stress conditions like salinity or ...

Mechanical stress determines the configuration of TGFβ activation in articular cartilage

Nature Communications, 2021
Our incomplete understanding of osteoarthritis (OA) pathogenesis has significantly hindered the development of disease-modifying therapy. The functional relationship between subchondral bone (SB) and articular cartilage (AC) is unclear.

Mechanical interaction between additive-manufactured metal lattice structures and bone in compression: implications for stress shielding of orthopaedic implants.

Journal of The Mechanical Behavior of Biomedical Materials, 2021
One of the main biomechanical causes for aseptic failure of orthopaedic implants is the stress shielding. This is caused by an uneven load distribution across the bone normally due to a stiff metal prosthesis component, leading to periprosthetic bone ...

Stress mechanisms in hypertension [PDF]

Postgraduate Medical Journal, 1986
Summary Recent studies of stress mechanisms in hypertension have focussed on the cardiovascular and neuroendocrine reactions to challenging or threatening psychosocial stimuli. Fixed hypertension may develop in some animal models following chronic exposure to psychosocial conflict.

The Role of Mechanical Stresses in Angiogenesis [PDF]

Critical Reviews in Biomedical Engineering, 2005
Angiogenesis is the formation of new capillary blood vessels from preexisting vessels. It is involved in many normal and diseased conditions, as well as in the application of tissue-engineered products. There has been extensive effort made to develop strategies for controlling pathological angiogenesis and for promoting vascularization in biomedical ...
