A microtubule nucleates from a γ-tubuUn complex, which consists of γ-tubulin, proteins from the SPC971SPC98 family, and the WD40 motif protein GCP-WD. We analyzed the phylogenetic relationships of the genes encoding these proteins and found that the components of this complex are widely conserved among land plants and other eukaryotes. By contrast, the interphase and mitotic arrays of microtubules in land plants differ from those in other eukaryotes. In the interphase cortical array, the majority of microtubules nucleate on existing microtubules in the absence of conspicuous microtubule organizing centers （MTOCs）, such as a centrosome. During mitosis, the spindle also forms in the absence of conspicuous MTOCs. Both poles of the spindle are broad, and branched structures of microtubules called microtubule converging centers form at the poles. In this review, we hypothesize that the microtubule converging centers form via microtubule-dependent microtubule nucleation, as in the case of the interphase arrays. The evolutionary insights arising from the molecular basis of the diversity in microtubule organization are discussed.

Fulminant hepatitis is a serious, life-threatening disorder and is associated with inflammatory cytokines produced by Kupffer cells. However, a number of clinical trials for the treatment of fulminant hepatitis did not show enough substantial benefits. Since NF-κB is a key mediator of inflammatory response in Kupffer cells, NF-κB decoy would be an attractive candi-datefor the treatment of fulminant hepatitis.

Determinants of Marketability for Organic Biomass Liquid Fertilizer from Human Waste in Da Nang City, Vietnam

引用

Journal of Environmental Protection 2017年第11期8卷 1354-1371页

作者： Buixuan Hong Yoshifumi Takahashi mitsuyasu Yabe Graduate School of Bioresource and Bioenvironmental Science Department of Agricultural and Resource Economics Faculty of Agriculture Kyushu University Fukuoka Japan

Recently, 90 tons of human waste per day are collected from private residences, offices, and public facilities in Da Nang City. Meanwhile, farmers in this region have to allocate 10% - 20% of rice sales for purchasing chemical fertilizer. Therefore, it is essential to be adopted more inexpensive organic fertilizer. To deal with these problems, Japan International Cooperation Agency (JICA) has signed a contract with Da Nang city government about human waste treatment and production of organic biomass liquid fertilizer (OBLF) in 2015. The aims of this project are to promote the use of OBLF in farming and improve public awareness of environmental protection. 530 respondents were interviewed at Hoa Vang districts of Da Nang city, and data was analyzed by Contingent Valuation Method (CVM) under double bounded dichotomous choice approach. The results have revealed that 436 respondents (82%) agreed to use OBLF. The farmers’ WTP depends on factors including household income, experience in using organic fertilizer, awareness of environment and training of organic fertilizer in the past. The estimated price for OBLF was 94,856 VND (4.0 USD)/ton. The cost that farmers paid for OBLF was lower than that of current available chemical fertilizers in Da Nang city. This proves that marketability seems to be existed for OBLF product in Da Nang city. From these findings, the government should have policies to support and subsidize the farmers to encourage them to use OBLF in a large scale of cultivation. Furthermore, establishment of a market to consume the organic products harvested from cultivated areas using OBLF is also recommended.

Journal of Water Resource and Protection 2015年第12期7卷 897-908页

作者： Phouthivong Khamsay Yoshifumi Takahashi Hisako Nomura mitsuyasu Yabe Laboratory of Environmental Economics Division of International Agricultural and Resource Economics and Business Administration Department of Agricultural and Resource Economics Faculty of Agriculture Kyushu University Fukuoka Japan

Using choice experiment, the objective of this study is to estimate international tourists’ preferences and willingness to pay for ecofriendly services which related to river and natural environment conservation of hotel industry in Vangvieng, a popular tourist town in Lao PDR. We used the mixed logit to take into account of preference heterogeneity by allowing coefficients to be normally distributed and assumed to vary among individuals. The result shows that all ecofriendly practices offered in this study are significantly preferred by tourists. Income, age, and education did not have significant effect on the probability of choosing ecologically friendly practices of hotel and attributes to support the ecotourism of the area;however, this study provides important information that female tourists are more receptive to a new alternative. These findings do not only support the provision of good and green services in Vangvieng Town, but will also be useful for policy maker to enhance the sustainability of ecotourism in Laos.

RTL Partial Scan Design System: REPS

According to increase of circuitry numbers of LSI, the test application time of a full scan design method becomes one of the bottleneck problems for the LSI productivity. The test application time is corresponding to the test length, thus the reduction of the test length in a scan design is strongly required. In this paper, we propose a partial scan design system at RT level design, named REPS, to reduce the test application time. REPS has the following new features: (1) a scan register selection method at RT level; (2) a DFT database is prepared to estimate test length of blocks; and (3) a DFT strategy generation for the shortest test length. We applied REPS to some test designs for a practical LSI that described at RT level. It is found that REPS estimates an accurate test length for an LSI at RTL, i.e. the error of the length is less than 10% from that at the gate level. As a result, the test length generated by the partial scan design method was 37% shorter than that by the conventional full scan design method.

Membrane trafficking to the protein storage vacuole （PSV） is a specialized process in seed plants. However, this trafficking mechanism to PSV is poorly understood. Here, we show that three types of Beige and Chediak-Higashi （BEACH）-domain proteins contribute to both vacuolar protein transport and effector- triggered immunity （ETI）. We screened a green fluorescent seed （GFS） library of Arabidopsis mutants with defects in vesicle trafficking and isolated two allelic mutants gfs3 and gfs12 with a defect in seed pro- tein transport to PSV. The gene responsible for the mutant phenotype was found to encode a putative pro- tein belonging to group D of BEACH-domain proteins, which possess kinase domains. Disruption of other BEACH-encoding loci in the gfs12 mutant showed that BEACH homologs acted in a cascading manner for PSV trafficking. The epistatic genetic interactions observed among BEACH homologs were also found in the ETI responses of the gfs12 and gfs12 bchb-1 mutants, which showed elevated avirulent bacterial growth. The GFS12 kinase domain interacted specifically with the pleckstrin homology domain of BchCl. These results suggest that a cascade of multiple BEACH-domain proteins contributes to vacuolar protein transport and plant defense.
