In Situ Measurements of Protein Forces and Intracellular Ca 2+ under Fluid Shear Stimuli

Roles of cell confluency and fluid shear in 3-dimensional intracellular forces in endothelial cells.

We use a novel 3D inter-/intracellular force microscopy technique based on 3D traction force microscopy to measure the cell-cell junctional and intracellular tensions in subconfluent and confluent vascular endothelial cell (EC) monolayers under static and shear flow conditions. We found that z-direction cell-cell junctional tensions are higher in confluent EC monolayers than those in subconflue...

I-2: Effects of Pre and Postnatal Protein under

Background: Protein-energy malnutrition is the most prevalent form of nutritional disorder in developing countries. Several studies have demonstrated that reproductive performance in adulthood is partially determined by a variety of extrinsic factors from conception to birth. Among these factors, maternal nutrition during fetal and neonatal life plays a key role as it can affect the reproductiv...

Internal Forces in Piles “Under External Forces and Earthquake in Homogeneous and Nonhomogeneous Media”

Stochastic spreading of intracellular Ca(2+) release.

We study the spreading of calcium-induced calcium release with the stochastic DeYoung-Keizer-model of the inositol 1,4,5-trisphosphate receptor channel. The model shows a transition from isolated release events to steadily propagating waves with increasing IP3 concentration. A state--stochastic backfiring--was found in the regime of steady propagation. The model can be reduced by an adiabatic e...
