The Effect of Liver Hydrolysate on Chronic Ethanol-Induced Hepatic Injury in Normal Rats

Biological and Pharmaceutical Bulletin (2020)

Kotaro Yamada Kazuma Ueda Hitoshi Shirakawa Puspo Edi Giriwono Satoru Honda

The mechanism underlying the improvement in hepatic function by liver hydrolysate (LH) after ethanol-induced hepatic injury is unclear. Therefore, we investigated the effects of LH administration on chronic ethanol-induced hepatic injury in normal rats and the mechanism underlying the improvement of its symptoms by LH. LH attenuated liver damage and reduced oxidative stress after chronic ethanol-induced hepatic injury in normal rats. LH treatment reduced hepatic injury biomarkers of plasma aspartate aminotransferase (AST) and alanine aminotransferase (ALT). LH treatment also decreased levels of 8-hydroxy-deoxyguanosine (8-OHdG) as oxidative stress marker. LH may prove beneficial to prevent the liver damage of chronic ethanol, at least in part, by alleviating oxidative stress.

Recovery of Simulated Fuel Debris by Remote Control Robot for Decommissioning Work

2022 IEEE International Conference on Mechatronics and Automation (ICMA) (2021)

Naoki Igo Shota Yamaguchi Noriyuki Kimura Kazuma Ueda Kazuma Kobayashi

This research aims to realize a remote control robot that can play an active role in decommissioning work. We have developed a remote control robot consisting of a main-unit and a sub-unit. The robot has a function to retrieve fuel debris. The main-unit is mainly responsible for raising and lowering the sub-unit by 3.2[m]. The sub-unit mainly performs the task of grasping the fuel debris. We participated in the Creative Robot Contest for Decommissioning with the robot we created. The Creative Robot Contest for Decommissioning is a robotics contest that aims to develop human resources for decommissioning work. We were able to complete all the tasks given to us in the contest. Therefore, we were able to demonstrate the potential of our robot to contribute to decommissioning work.

Development of Tomato Harvest Support System Using Mixed Reality Head Mounted Display

2022 IEEE 4th Global Conference on Life Sciences and Technologies (LifeTech) (2022)

Ryota Goka Kazuma Ueda Shota Yamaguchi Noriyuki Kimura Kenji Iseya

At present, many Japanese tomato farmers harvest manually to select harvest candidates considering ripeness and blemishes of each fruit. Therefore, part-time workers and new farmers have problems such as stability of harvest quality and work efficiency because they do not have a good eye for harvest candidates. Thus, we propose a system using Head Mounted Display (HMD) and User Datagram Protocol (UDP) that a computer gets camera images of a subjective perspective in real-time and finally, HMD presents the information which is obtained by image processing in Mixed Reality (MR) space. This system enables to tell the information such as harvest candidates, sugar content, and acidity of tomatoes to workers without disturbing the harvesting operation. In this paper, we describe the adopted HMD and the original architecture that we devised to achieve harvesting support in mixed reality except for image processing part, and moreover, we validate the proposed system.

Robots Climbing Up and Down a Steep Stairs and Robots Retrieving Objects from High Places

Journal of Robotics and Mechatronics (2022)

Naoki Igo Shota Yamaguchi Noriyuki Kimura Kazuma Ueda Kenji Iseya

We designed and fabricated robots with various mechanisms to solve the problems set in the Creative Robot Contest for Decommissioning. Robots with various mechanisms were designed and manufactured to solve the problems set by the Creative Robot Contest for Decommissioning. More specifically, a mechanism that can climb up the stairs robustly was realized by attaching claws to the crawlers to solve the problem of climbing up a steep staircase while carrying a heavy load. For the task of retrieving simulated fuel debris from a high location, we developed a mechanism to raise and lower the robot and a mechanism to retrieve simulated fuel debris without fail. Consequently, we realized the idea of robot technology required for decommissioning work and training human resources involved in decommissioning work.

Fermented barley extract supplementation ameliorates metabolic state in stroke-prone spontaneously hypertensive rats

Bioscience Biotechnology and Biochemistry (2015)

Hitoshi Shirakawa Puspo Edi Giriwono Kazuki Oguchi Kazuma Ueda Hideki Hokazono

We studied the effects of fermented barley extract P (FBEP) in stroke-prone spontaneously hypertensive rats (SHRSP). Male 10-week-old SHRSP were divided into three groups that were fed: an AIN-93M diet (control), a low dose of FBEP (4 g/kg; FBEP1), and a high dose of FBEP (20 g/kg; FBEP2) for three weeks. Hypertension was significantly improved by the use of FBEP supplementation. The FBEP diet improved plasma triglyceride, insulin sensitivity, enhanced plasma catalase, and superoxide dismutase activities, and decreased plasma 8-hydroxy-2'-deoxyguanosine levels. In addition, the FBEP diet upregulated hepatic antioxidative genes and modulated Nrf2 protein levels in the liver. Furthermore, a single oral dose of FBEP (2 g/kg body weight) was able to lower blood pressure in SHRSP. In conclusion, our data suggest that increased expression of hepatic antioxidative genes and modulation of Nrf2 may play a role in the regulation of metabolic diseases in SHRSP consuming a FBEP diet.
