Osteogenic Effects of Rest Inserted and Continuous Cyclic Tensile Strain on hASC Lines with Disparate Osteodifferentiation Capabilities
ANNALS OF BIOMEDICAL ENGINEERING, 37(5), 955–965.
author keywords: Adipose derived stem cells; Mesenchymal stem cells; Osteogenesis; Mechanical effects on cells and tissues; Tissue engineering
MeSH headings : Adipose Tissue / cytology; Adult Stem Cells; Calcium / metabolism; Cell Differentiation; Cell Proliferation; Cells, Cultured; Humans; Mesenchymal Stem Cells; Models, Biological; Osteogenesis / physiology; Stress, Mechanical; Tensile Strength; Tissue Engineering / methods
TL;DR:
Results showed that both continuous and rest inserted cyclic tensile strain increased the amount and rate of calcium deposition for both high and low calcium depositing hASC lines as compared to unstrained controls, suggesting that mechanical loading has a greater effect on cell lines that already have an innate ability to produce bone.

Biomechanical evaluation of postures assumed when harvesting from bush crops
INTERNATIONAL JOURNAL OF INDUSTRIAL ERGONOMICS, 39(2), 347–352.
author keywords: Harvesting postures; Ergonomic intervention; EMG
TL;DR:
The results indicate that the beneficial aspects of the knee support intervention appear to be outweighed by reduced productivity and the high degree of trunk flexion and that the current strategy used by these workers of alternating between the various harvesting postures may be the best strategy available.
