Embryonic stem (ES) cells are exposed to fluid-mechanical forces, such as cyclic strain and shear stress, during the process of embryonic development but much remains to be elucidated concerning the role of fluid-mechanical forces in ES cell differentiation. Here, we show that cyclic strain induces vascular smooth muscle cell (VSMC) differentiation in(More)
We developed a compliant tube-type flow-loading apparatus that allows simultaneous application of physiological levels of shear stress and cyclic stretch to cultured cells and examined gene responses to a combination of the two forces. Human umbilical vein endothelial cells were exposed to shear stress and/or cyclic stretch for 24h, and changes in the mRNA(More)
Endothelial progenitor cells (EPCs) are mobilized from bone marrow to peripheral blood and contribute to angiogenesis in tissues. In the process, EPCs are exposed to the shear stress generated by blood flow and tissue fluid flow. Our previous study showed that shear stress promotes differentiation of EPCs into mature endothelial cells. In this study, we(More)
Endothelial cells (ECs) release ATP in response to shear stress, a mechanical force generated by blood flow, and the ATP released modulates EC functions through activation of purinoceptors. The molecular mechanism of the shear stress-induced ATP release, however, has not been fully elucidated. In this study, we have demonstrated that cell surface ATP(More)
Space is represented by integrating egocentric and allocentric reference frames; however, little is known about the role of these independent reference frames in number representation. Using patients with unilateral pathologic pain in one limb, we investigated whether number representation is closely linked to space representation by evaluating visual(More)
This study's aim was to build a web service that automatically collects and tests hypotheses for possible allergy risks. We crowdsourced for unknown allergy risks, and obtained odds ratios. By using the collected hypotheses, we built a web service that estimates allergy risks from a questionnaire (consisting of 10 questions that we gathered from the(More)
In order to help people suffering from autism spectrum disorder (ASD), assistance systems have been developed with a focus on enabling ASD people to adapt to activities of daily living (e.g., augmentative and alternative communication systems [1]). However, if we reverse our viewpoint, we can develop a new concept for the assistance system: letting normal(More)
Previous models or hypotheses of autism spectral disorder (ASD) failed to take into full consideration the chronological and causal developmental trajectory, leading to the emergence of diverse phenotypes through a complex interaction between individual etiologies and environmental factors. Those phenotypes include persistent deficits in social(More)
Maintaining an appropriate distance from others is important for establishing effective communication and good interpersonal relations. Autism spectrum disorder (ASD) is a developmental disorder associated with social difficulties, and it is thus worth examining whether individuals with ASD maintain typical or atypical degrees of social distance.
