Promoting effect and Recovery Activity from physical stress of the fruit of Morus alba
Biofactors, 2004Co-Authors: Keum Hee HwangAbstract:We examined the effects of the fruit of M. alba extracts on the changes of the monoamine oxidase (MAO) activities during and after the physical exercise in rat. Each Activity was measured by used serotonin(5-HT) and benzylamine as substrate. Lactate dehydrogenase(LDH) Activity and the concentrations of lactate in blood which were clinical indexes of physical exercise were also determined to compare with the relation of MAO activities. Those activities during and after the physical exercise have different tendency in each other enzyme. MAO-A Activity was sharply decreased with stress by physical activities compared to the normal group, whereas MAO-B Activity was increased for 60 minutes after exercise. All of these indexes were recovered to normal state by oral administration of extract of M. alba. These results of this study suggested M. alba may modulate the MAO activities during exercise and promote the capability of physical activities and show anti-stress effect. In general, MAO inhibitors have been used drugs for the purpose of treatment Parkinson's disease, dementia, deprression. These results can apply to produce the health and functional foods that have modulating effects for these diseases.

Engineering Applications Using Probabilistic Aftershock Hazard Analyses: Aftershock Hazard Map and Load Combination of Aftershocks and Tsunamis
Geosciences, 2017Co-Authors: Byunghyun Choi, Tatsuya Itoi, Akemi Nishida, Tsuyoshi TakadaAbstract:After the Tohoku earthquake in 2011, we observed that aftershocks tended to occur in a wide region after such a large earthquake. These aftershocks resulted in secondary damage or delayed rescue and Recovery activities. In addition, it has been reported that there are regions where the intensity of the vibrations owing to the aftershocks was much stronger than those associated with the main shock. Therefore, it is necessary to consider the seismic risk associated with aftershocks. We used the data regarding aftershocks that was obtained from the Tohoku earthquake and various other historically large earthquakes. We investigated the spatial and temporal distribution of the aftershocks using the Gutenberg–Richter law and the modified Omori law. Subsequently, we previously proposed a probabilistic aftershock occurrence model that is expected to be useful to develop plans for Recovery activities after future large earthquakes. In this study, the probabilistic aftershock hazard analysis is used to create aftershock hazard maps. We propose a hazard map focusing on the probability of aftershocks on the scale of the main shock for use with a Recovery Activity plan. Following the lessons learned from the 2011 Tohoku earthquake, we focus on the simultaneous occurrence of tsunamis and aftershocks just after a great subduction earthquake. The probabilistic aftershock hazard analysis is used to derive load combination equations of the load and resistance factor design. This design is intended to simultaneously consider tsunamis and aftershocks for tsunami-resistant designs of tsunami evacuation buildings.

The Excess Demand for Housing
Social Media Communication Data for Recovery, 2019Co-Authors: Yuya ShibuyaAbstract:In this chapter, the author examines whether there was an excess demand for housing after the Great East Japan Earthquake and Tsunami. In other words, this chapter investigates the possibility of using the housing market data as one of the proxies for socio-economic Recovery Activity indicators (RQ1b). As described in Chap. 3, various studies related to the housing market after a large-scale disaster have been conducted. However, to the author’s best knowledge, there is a paucity of research on investigating whether the housing market data could be a proxy of one of the socio-economic Recovery Activity indicators. Thus, this chapter examines the housing market data between one year before and three years after the disaster in the disaster-stricken area. Findings of this chapter show that the prices of houses leased close to the building damage zone and located in the plains increased after the disaster, indicating that there was the excess demand for those leased houses. The price of houses within 3 km to the building damage zone and located in the plains started to increase particularly four months after the disaster until fifteen months after the disaster. This suggests that people in the disaster area needed to rent housing which are close to where they used to live before the disaster but are not inundated even if the prices were a bit higher. In addition, because related studies have recognized that housing is one of the key factor for life Recovery as described in Chap. 1, the author argues that the results support the appropriateness of using the housing market data as a proxy of one of the socio-economic Recovery activities. The rest of the chapter is constructed as follows. First, the target data is introduced in Sect. 5.1. In Sect. 5.2, the model and variables are explained. In Sect. 5.3, the results of the analysis are described, and the results are discussed in Sect. 5.4. Finally, 5.5 concludes the results.

The Excess Demand for Used Cars
Social Media Communication Data for Recovery, 2019Co-Authors: Yuya ShibuyaAbstract:The goal of this chapter is to show the appropriateness of using used-car market data as a proxy of one of the socio-economic Recovery Activity indicators after the Great East Japan Earthquake and Tsunami (RQ1a). In Chap. 2, the author describes the news reports and the interviews with used-car dealers which revealed people in the disaster-impacted area needed to buy used cars when they started to rebuild their daily lives, such as going to workplaces. In this chapter, by conducting quantitative analysis to support the findings of Chap. 2. Also, the study further clarifies what types of used cars and what kinds of car features were demanded in the disaster-stricken area and when. The finding of this chapter is that lower-price used cars and used cars with larger carrying capacity were particularly needed in the disaster-damaged area after the Great East Japan Earthquake and Tsunami. In addition, the author finds that car types which people in the damaged area needed depend on the phase of Recovery. By showing there was the excess demand for used cars, this chapter supports that the used-car market data is appropriate to be used as a proxy of the socio-economic Recovery activities. The rest of this chapter is constructed as follows. First, In Sect. 4.1, the data for the study is introduced. In Sect. 4.2, the model is explained. Section 4.3 provides the results of the analysis, which the author discusses the results in 4.4. Lastly, the chapter is concluded in Sect. 4.5.

The Arabidopsis KS-type dehydrin recovers lactate dehydrogenase Activity inhibited by copper with the contribution of His residues
Plant Science, 2016Co-Authors: Masakazu Hara, Shuhei Monna, Takae Murata, Taiyo Nakano, Shono Amano, Markus Nachbar, Hermann WatzigAbstract:Abstract Dehydrin, which is one of the late embryogenesis abundant (LEA) proteins, is involved in the ability of plants to tolerate the lack of water. Although many reports have indicated that dehydrins bind heavy metals, the physiological role of this metal binding has not been well understood. Here, we report that the Arabidopsis KS-type dehydrin (AtHIRD11) recovered the lactate dehydrogenase (LDH) Activity denatured by Cu 2+ . The LDH Activity was partially inhibited by 0.93 μM Cu 2+ but totally inactivated by 9.3 μM Cu 2+ . AtHIRD11 recovered the Activity of LDH treated with 9.3 μM Cu 2+ in a dose-dependent manner. The Recovery Activity of AtHIRD11 was significantly higher than those of serum albumin and lysozyme. The conversion of His residues to Ala in AtHIRD11 resulted in the loss of the Cu 2+ binding of the protein as well as the disappearance of the conformational change induced by Cu 2+ that is observed by circular dichroism spectroscopy. The mutant protein showed lower Recovery Activity than the original AtHIRD11. These results indicate that AtHIRD11 can reactivate LDH inhibited by Cu 2+ via the His residues. This function may prevent physiological damage to plants due to heavy-metal stress.
