When Textile Design Meets Contemporary Art - Sudo Reiko: Making NUNO Textiles Exhibition at the Centre for Heritage, Arts and Textile, Hong Kong
No full textIn 2019, the Centre for Heritage, Arts and Textile (CHAT) in Hong Kong held an unprecedented solo exhibition by famed textile designer Reiko Sudo, entitled “Sudo Reiko: Making NUNO Textiles” Exhibition. This special exhibition showcased the classic textile designs of Sudo, as well as the stories of Japanese traditions and the local textile industry embedded in Sudo’s textiles from multiple perspectives, such as textile design, contemporary art, and creative media. The aims of this exhibition commentary are to analyze the characteristics of this special exhibition and how it responds to the contemporary concerns of museum studies and textile studies, and to provide relevant suggestions. Under the theme of “weaving the past and present”, this essay is divided into five topics: textiles and museums, from textile design to contemporary art, display and interactivity of textiles, textiles and place, and rethinking textile special exhibitions. The author argues that adopting a cross-disciplinary approach to the curation of textile exhibitions encourages curators, artists, and audiences to rediscover the diversified meanings of textile collections. For exhibitions related to the textile industry, a more inclusive narrative can be achieved by including the voices of local textile workers. There is increasing interest in the academic discussion of textiles and museums in Europe and America. However, such discussions in Asia have been limited. It is expected that this essay will serve to diversify the current academic discussions in the fields of textile and cultural studies and museum studies by providing a case study from Hong Kong and to promote and raise awareness of textile curation among museum professionals and researchers in Hong Kong and Asia.link_to_subscribed_fulltex
Association of pharaonis phoborhodopsin with its cognate transducer decreases the photo-dependent reactivity by water-soluble reagents of azide and hydroxylamine.
No full textpharaonis phoborhodopsin (ppR; also pharaonis sensory rhodopsin II, psRII) is a receptor of the negative phototaxis of Natronobacterium pharaonis. In halobacterial membrane, ppR forms a complex with its transducer pHtrII, and this complex transmits the light signal to the sensory system in the cytoplasm. In the present work, the truncated transducer, t-Htr, was used which interacts with ppR [Sudo et al. (2001) Photochem. Photobiol. 74, 489–494]. Two water-soluble reagents, hydroxylamine and azide, reacted both with the transducer-free ppR and with the complex ppR/t-Htr (the complex between ppR and its truncated transducer). In the dark, the bleaching rates caused by hydroxylamine were not significantly changed between transducer-free ppR and ppR/t-Htr, or that of the free ppR was a little slower. Illumination accelerated the bleach rates, which is consistent with our previous conclusion that the reaction occurs selectively at the M-intermediate, but the rate of the complex was about 7.4-fold slower than that of the transducer-free ppR. Azide accelerated the M-decay, and its reaction rate of ppR/t-Htr was about 4.6-fold slower than free ppR. These findings suggest that the transducer binding decreases the water accessibility around the chromophore at the M-intermediate. Its implication is discussed
Tyr-199 and charged residues of pharaonis Phoborhodopsin are important for the interaction with its transducer.
No full textpharaonis Phoborhodopsin (ppR; also pharaonis sensory rhodopsin II, psRII) is a retinal protein in Natronobacterium pharaonis and is a receptor of negative phototaxis. It forms a complex with its transducer, pHtrII, in membranes and transmits light signals by protein-protein interaction. Tyr-199 is conserved completely in phoborhodopsins among a variety of archaea, but it is replaced by Val (for bacteriorhodopsin) and Phe (for sensory rhodopsin I). Previously, we (Sudo, Y., M. Iwamoto, K. Shimono, and N. Kamo, submitted for publication) showed that analysis of flash-photolysis data of a complex between D75N and the truncated pHtrII (t-Htr) give a good estimate of the dissociation constant KD in the dark. To investigate the importance of Tyr-199, KD of double mutants of D75N/Y199F or D75N/Y199V with t-Htr was estimated by flash-photolysis and was ~10-fold larger than that of D75N, showing the significant contribution of Tyr-199 to binding. The KD of the D75N/t-Htr complex increased with decreasing pH, and the data fitted well with the Henderson-Hasselbach equation with a single pKa of 3.86 ± 0.02. This suggests that certain deprotonated carboxyls at the surface of the transducer (possibly Asp-102, Asp-104, and Asp-106) are needed for the binding
Interaction of the Halobacterial Transducer to a Halorhodopsin Mutant Engineered so as to Bind the Transducer : Cl- Circulation within the Extracellular Channel
No full textAn alkali-halophilic archaeum, Natronomonas pharaonis, contains two rhodopsins that are halorhodopsin (phR), a light-driven inward Cl- pump and phoborhodopsin (ppR), the receptor of negative phototaxis functioning by forming a signaling complexes with a transducer, pHtrII. Previously, we reported that the phR double mutant, P240T/F250YphR, can bind with pHtrII [Y. Sudo et al. (2006) J. Mol. Biol. 357, 1274-1282]. This mutant itself can transport Cl-, while the net transport was stopped upon formation of the complex. The flash photolysis data were analyzed by a scheme in which phR ⇒ P1 → P2 → P3 → P4 → phR. The P3 of the wild-type and the double mutant contained two components, X- and O-intermediates. After the complex formation, however, the P3 of the double mutant lacked the X-intermediate. These observations imply that the X-intermediate (probably the N-intermediate) is the state having Cl- in the cytoplasmic binding site and that the complex undergoes an extracellular Cl- circulation due to the inhibition of formation of the X-intermediate
On the Chronaxie of the Muscle Fibre
No full textThe author carried out some experiments investicating the relation between the capacity and the applied voltage of the electrical current need to excite the Frog's muscle by Lapicque's chronaximètre. In these experiments the exact results were obtained only by stimulation of a single muscle fibre (M. basihyoideus) by a capillar pore electrode after Pratt. The strength-duration curve obtained by such a method is a smooth and continuous hyperbola as shown by Hoorweg and Weiss. From these results the author concluded that a muscle fibre has only one excitable substance. Calculating the data, the author noticed that the chronaxie is the time in which the muscle excites with the minimum energy. The action of curare upon muscle fibre was also investigated. It acts only upon. rheobase and elevates it, but not upon chronaxie at all
A note upon the electrotonus
No full textThe author made some experiments about the electrotonus and obtained the next results; 1) The polarisation current and the excitation current summate in same direction and reduce in opposite direction. 2) The rest action of the polarisation current is due to the unequilibrium of ions of the electrical doubre layer by Bernstein. 3) The changes of the electric resistances of the neighbourhoods of the poles are due to the changes of permeability of the membrane. 4) The electrotonus and the mechanical impulse summate in cathode and reduce each other in anode

Japanese Business Disclosure and Accounting Requirements
No full textThe trend toward a global securities market has been hindered by divergent national accounting and auditing standards. The increasing international focus of Japanese business and the diversification of Japanese corporations has highlighted the need for Japanese accounting standards to become more consistent with international standards. The author examines the progress Japan has made since 1986 in harmonizing their accounting and auditing standards with international practices. The author also examines recent revisions to Japanese security reporting regulations which make them more compatible with similar U.S. regulations

Fine‐scale distribution of tropical seagrass beds in Southeast Asia
No full textSoutheast Asia is a hotspot of global seagrass diversity, offering valuable ecosystem services for human life. However, historically, there have been large gaps in the scientific knowledge of the distribution of seagrass beds in this region. Information on the distribution has not been updated in global databases since the publication of the World Seagrass Atlas in 2003, which was based on data mostly obtained up until the late 1990s. We collected more recent data on seagrass bed distribution from nine ASEAN countries plus southern China and southern Japan, and integrated these data into a geographic information system (GIS)-database. A total of 1,064 polygon data and 937 points data were uploaded in this paper, which were obtained from 107 scientific articles and reports published after 2000, including those written in local languages. Among them, 7.3% of the data have associated information on seagrass bed size and 35.3% have associated information on seagrass species composition. Data obtained from Vietnam, Cambodia, Singapore, Timore-Leste and Southern China cover almost all the coastlines of each country, whereas data for the Philippines, Indonesia, Malaysia, Myanmar, Thailand still have large gaps in areal coverage. The data set has a few points from Brunei Darussalam, the Paracel Islands, Spratly Islands and Pratas Islands, which are areas that we lacked information on for a long time. The obtained data will be useful to understand the current status of seagrass beds and to help facilitate better conservation and management of coastal areas in this region.
