Eukaryotic flagella and cilia generate rhythmical beating motions. When the structure is partially defective, the motility is severely impaired. We have developed a high-pressure microscope that is optimized both for the best image formation and for the stability to hydrostatic pressure up to 150 MPa. Here, we show that high hydrostatic pressure induces vigorous beating motion of Chlamydomonas flagella with defect structures. In addition, our results suggest that application of pressure increased intra-flagella Ca2+ concentration. The present technique could be extended to study other protein machineries and cell dynamics. [high-pressure microscopy, flagellar motility, bacterial motility, chlamydomonas, intracellular calcium concentration]

Recently isotactic poly(4methyl1pentene) (P4MP1) has been found to selectively absorb long-chain alkanes from alkane mixed systems. In this article, we introduce the idea of this study from the pressure-temperature phase diagram. We also show that such selective absorption characteristics can be explained from a simple model, namely Asakura-Oosawa theory, and the relationship with molecular recognition is explained. [host-guest structures, selective absorption, Asakura-Oosawa theory, molecular recognition, melting curve maximum, P4MP1, PMP, SPS]
