The mechanosensitive Piezo1 channel is required for bone formation
eLife, 2019 Mechanical load of the skeleton system is essential for the development, growth, and maintenance of bone. However, the molecular mechanism by which mechanical stimuli are converted into osteogenesis and bone formation remains unclear. Here we report that

What Is Phloem Unloading? [PDF]
Plant Physiology, 1990 Several studies of phloem unloading have failed to distinguish between transport events occurring at the sieve element/companion cell boundary and subsequent short-distance transport through parenchyma cells. Indirect evidence has been obtained for symplastic unloading in storage and utilization sinks. In other sinks transfer to the apoplast may occur,

Method for calculating coefficient of collapsibility of loess under unloading
Yantu gongcheng xuebao, 2019 The concomitant process of unloading and collapse exists in the loess between piles of self-weight collapse loess site subjected to inundation. It is difficult to calculate the collapse deformation of loess under unloading.
