Standing, Walking, and Sitting Support Robot Based on User State Estimation Using a Small Number of Sensors

Autor: Mizuki Takeda, Kaiji Sato, Yasuhisa Hirata, Takahiro Katayama, Yasuhide Mizuta, Atsushi Koujina

Publikováno v: IEEE Access, Vol 9, Pp 152677-152687 (2021)

With the aging of the population and the consequent severe shortage of caregivers, the demand for care robots to assist the elderly is increasing. However, care robots have yet to be widely adopted owing to cost constraints and anxiety issues due to

Verbal guidance for sit-to-stand support system

Autor: Mizuki Takeda, Yasuhisa Hirata, Yueh-Hsuan Weng, Takahiro Katayama, Yasuhide Mizuta, Atsushi Koujina

Publikováno v: ROBOMECH Journal, Vol 7, Iss 1, Pp 1-10 (2020)

Abstract Artificial intelligence (AI)-based robots have become popular in various fields, thereby increasing the demand for care robots. Such care robots recognize or estimate factors such as human states and then perform actions depending on the est

Nicotine- and Tar-Free Cigarette Smoke Induces Cell Damage Through Reactive Oxygen Species Newly Generated by PKC-Dependent Activation of NADPH Oxidase

Autor: Hiroshi Asano, Takahiro Horinouchi, Yosuke Mai, Osamu Sawada, Shunsuke Fujii, Tadashi Nishiya, Masabumi Minami, Takahiro Katayama, Toshihiko Iwanaga, Koji Terada, Soichi Miwa

Publikováno v: Journal of Pharmacological Sciences, Vol 118, Iss 2, Pp 275-287 (2012)

We examined cytotoxic effects of nicotine/tar-free cigarette smoke extract (CSE) on C6 glioma cells. The CSE induced plasma membrane damage (determined by lactate dehydrogenase leakage and propidium iodide uptake) and cell apoptosis {determined by MT

Neuronal Injury Induces Cytokine-Induced Neutrophil Chemoattractant-1 (CINC-1) Production in Astrocytes

Autor: Takahiro Katayama, Hiroki Tanaka, Tadashi Yoshida, Takashi Uehara, Masabumi Minami

Publikováno v: Journal of Pharmacological Sciences, Vol 109, Iss 1, Pp 88-93 (2009)

Accumulating evidence indicates a pivotal role for neuroinflammation in ischemic and excitotoxic brain injury. Cytokine-induced neutrophil chemoattractant-1 (CINC-1) is a CXC chemokine implicated in the infiltration of inflammatory cells into the bra

Brain Cytokines and Chemokines: Roles in Ischemic Injury and Pain

Autor: Masabumi Minami, Takahiro Katayama, Masamichi Satoh

Publikováno v: Journal of Pharmacological Sciences, Vol 100, Iss 5, Pp 461-470 (2006)

Abstract.: Cytokines and chemokines were originally identified as essential mediators for inflammatory and immune responses. Enhanced production and release of cytokines/chemokines are observed also in the central nervous system (CNS) under diverse p

Accumulating microglia phagocytose injured neurons in hippocampal slice cultures: involvement of p38 MAP kinase.

Autor: Takahiro Katayama, Hayato Kobayashi, Toshiyuki Okamura, Yuko Yamasaki-Katayama, Tatsuya Kibayashi, Hiroshi Kimura, Keiko Ohsawa, Shinichi Kohsaka, Masabumi Minami

Publikováno v: PLoS ONE, Vol 7, Iss 7, p e40813 (2012)

In this study, microglial migration and phagocytosis were examined in mouse organotypic hippocampal slice cultures, which were treated with N-methyl-D-aspartate (NMDA) to selectively injure neuronal cells. Microglial cells were visualized by the expr
