Human dental pulp cells (hDPCs) are a promising resource for regenerative medicine and tissue engineering and can be used for derivation of induced pluripotent stem cells (iPSCs). However, current protocols use reagents of animal origin (mainly fetal bovine serum, FBS) that carry the potential risk of infectious diseases and unwanted immunogenicity. Here,(More)
Dental pulp cells (DPCs) of various species have been studied for their potentials of differentiation into functional neurons and secretion of neurotrophic factors. In canine, DPCs have only been studied for cell surface markers and differentiation, but there is little direct evidence for therapeutic potentials for neurological disorders. The present study(More)
We present EnhancedTouch, a novel bracelet-type wearable device for facilitating human-human physical touch. In particular, we aim to support children with autism spectrum disorder (ASD), who often exhibit particular communication patterns, such as lack of physical touch. EnhancedTouch is a unique device that can measure human-human touch events and provide(More)
The reprogramming of somatic cells into induced pluripotent stem cells (iPSCs) by defined transcription factors has been a well-established technique and will provide an invaluable resource for regenerative medicine. However, the low reprogramming efficiency of human iPSC is still a limitation for clinical application. Here we showed that the reprogramming(More)
Graphene oxide (GO) has recently been shown to be an excellent anode substrate for exoelectrogens. This study demonstrates the applicability of GO in recovering electricity from sewage wastewater. Anaerobic incubation of sludge with GO formed a hydrogel complex that embeds microbial cells via π-π stacking of microbially reduced GO. The rGO complex was(More)
The purpose of this study was to clarify the effect of Chinese propolis on the expression level of neurotrophic factors in dental pulp cells (DPCs). We also investigated that the effects of the conditioned medium (CM) of DPCs stimulated by the propolis against oxidative and endoplasmic reticulum (ER) stresses in human neuroblastoma SH-SY5Y cells, and on(More)
Nylon hydrolase degrades various aliphatic nylons, including nylon-6 and nylon-66. We synthesized a nylon-66 copolymer (M w = 22,900, M n = 7,400), in which a part of an adipoyl unit (32 % molar ratio) of nylon-66 was replaced with a succinyl unit by interfacial polymerization. To quantify the reaction rate of the enzymatic hydrolysis of nylons at the(More)
When magnetic moments (spins) are regularly arranged in a geometry of a triangular motif, the spins may not satisfy simultaneously their interactions with their neighbors. This phenomenon, called frustration, leads to numerous energetically equivalent magnetic states (ground states), which results in exotic states such as spin liquid and spin ice. Here we(More)
There are a number of systems and devices for spacial measurement which can be used to measure bodily motion. However, these systems are usually large or fixed with the environment. In this study, we propose a novel modular device that allows users to create geometric shapes in the real world and also a flexible sensing space within the created shape. Users(More)
