After six years of continuous effort, electronic photography is beginning to make progress, especially in industrial and commercial photo applications. For industrial locations, electronic photography has been a way of controlling environmental concerns as well as a way of creating greater cost efficiency.For commercial studios, digital still photography has allowed the direct input of product photography ready for placing in a final page, saving up to a week of production time in many cases.There is some usage in the photo journalism market of the electronic still image because of the speed of image availability and the ease of transmitting images. Early efforts were slowed because many felt that the image produced lacked resolution. More importantly, the exposure index of the analog systems was considerably under the exposure index 400 to 1600 films commonly used. New digital cameras from Kodak have come closer in meeting the needs of photo journalists both in resolution and exposure speed.

In this paper, I discuss recordization of "experience" on video sharing websites. Recently, rich contents can be treated by users on the Internet with the spread of video sharing websites. As a result of this spread, expression styles on the Internet are inceasing in number as well as in diversity. A number of users upload data of recorded "experience" to the Web. Moreover, this recordization of "experience" also became the expression activities by users. Based on this situation, this paper considers "experience value" created by records of various experiences on the Internet.

Human urinary trypsin inhibitor (UTI) is a proteoglycan composed of one core protein covalently linked to one glycosaminoglycan, which is a low sulfated chondroitin 4-sulfate. It is used as an anti-inflammatory medicine based on the protease inhibitory activity of the core protein. However, functions of the chondroitin sulfate have not been clarified. Recently, we succeeded in remodeling the UTI chondroitin sulfate to hyaluronan to create hyaluronan hybrid UTI, without changing the core protein. Here, we investigated the effect of the remodeled chondroitin sulfate on the activities of serine proteases. Native UTI showed stronger protease inhibitory activity than hyaluronan hybrid UTI or hydrolyzed glycosaminoglycan UTI. Chondroitin 4-sulfate chains with a small peptide derived from the native UTI did not show any protease inhibitory activity. These results suggest that the chondroitin sulfate chain linked covalently to core protein enhances protease inhibitor activity of UTI although the chondroitin sulfate chain itself does not.

The aim of this study was to investigate the effect of pH control by CO2 pressurization on the enzymatic hydrolysis of herbaceous feedstock in the calcium capturing by carbonation (CaCCO) process for fermentable sugar production. The pH of the slurry of 5% (w/w) Ca(OH)2-pretreated/CO2-neutralized rice straw could be controlled between 5.70 and 6.38 at 50 °C by changing the CO2 partial pressure (pCO2) from 0.1 to 1.0 MPa. A mixture of fungal enzyme preparations, namely, Trichoderma reesei cellulases/hemicellulases and Aspergillus niger β-glucosidase, indicated that pH 5.5–6.0 is optimal for solubilizing sugars from Ca(OH)2-pretreated rice straw. Enzymatic saccharification of pretreated rice straw under various pCO2 conditions revealed that the highest soluble sugar yields were obtained at pCO2 0.4 MPa and over, which is consistent with the expected pH at the pCO2 without enzymes and demonstrates the effectiveness of pH control by CO2 pressurization.

Cellobiose dehydrogenase (CDH) is a flavocytochrome catalyzing oxidation of the reducing end of cellobiose and cellooligosaccharides, and has a key role in the degradation of cellulosic biomass by filamentous fungi. Here, we use a lineup of glucose/xylose-mixed β-1,4-linked disaccharides and trisaccharides, enzymatically synthesized by means of the reverse reaction of cellobiose phosphorylase and cellodextrin phosphorylase, to investigate the substrate recognition of CDH. We found that CDH utilizes β-D-xylopyranosyl-(1→4)-D-glucopyranose (Xyl-Glc) as an electron donor with similar Km and kcat values to cellobiose. β-D-Glucopyranosyl-(1→4)-D-xylopyranose (Glc-Xyl) shows a higher Km value, while xylobiose does not serve as a substrate. Trisaccharides show similar behavior; i.e., trisaccharides with cellobiose and Xyl-Glc units at the reducing end show similar kinetics, while the enzyme was less active towards those with Glc-Xyl, and inactive towards those with xylobiose. We also use docking simulation to evaluate substrate recognition of the disaccharides, and we discuss possible molecular mechanisms of substrate recognition by CDH.

本研究では足底部位別での感覚情報の増加が立位姿勢調節に与える影響に着目し,足底部位別での機械受容感覚情報の役割を検討することを目的とした。対象は健常女子学生14名とした。被験者の足に合わせた4種類の足底刺激板(刺激なし,前足部中内側部,前足部外側部,後足部)上で静止立位足圧中心動揺を測定し,続いてクロステストによる足圧中心移動範囲を測定し分析した。クロステストにおける後方向移動範囲において,後足部刺激が刺激なしと前足部中内側刺激に比し有意に移動範囲の増大を認めた。今回の研究から足底部位別の役割として,視覚情報が低下した状況下では後足部の機械受容感覚情報増加は,後方向への足圧中心移動範囲を増大させるのに重要な情報を提供する機能を有していることが推測された。

According to whole-genome sequencing, Aspergillus niger produces multiple enzymes of glycoside hydrolases (GH) 31. Here we focus on a GH31 α-glucosidase, AgdB, from A. niger. AgdB has also previously been reported as being expressed in the yeast species, Pichia pastoris; while the recombinant enzyme (rAgdB) has been shown to catalyze tranglycosylation via a complex mechanism. We constructed an expression system for A. niger AgdB using Aspergillus nidulans. To better elucidate the complicated mechanism employed by AgdB for transglucosylation, we also established a method to quantify glucosidic linkages in the transglucosylation products using 2D NMR spectroscopy. Results from the enzyme activity analysis indicated that the optimum temperature was 65 °C and optimum pH range was 6.0–7.0. Further, the NMR results showed that when maltose or maltopentaose served as the substrate, α-1,2-, α-1,3-, and small amount of α-1,1-β-linked oligosaccharides are present throughout the transglucosylation products of AgdB. These results suggest that AgdB is an α-glucosidase that serves as a transglucosylase capable of effectively producing oligosaccharides with α-1,2-, α-1,3-glucosidic linkages.

Ovomucin, a hen egg white protein, is characterized by its hydrogel-forming properties, high molecular weight, and extensive O-glycosylation with a high degree of sialylation. As a commonly used food ingredient, we explored whether ovomucin has an effect on the gut microbiota. O-Glycan analysis revealed that ovomucin contained core-1 and core-2 structures with heavy modification by N-acetylneuraminic acid and/or sulfate groups. Of the two mucin-degrading gut microbes we tested, Akkermansia muciniphila grew in medium containing ovomucin as a sole carbon source during a 24 h culture period, whereas Bifidobacterium bifidum did not. Both gut microbes, however, degraded ovomucin O-glycans and released monosaccharides into the culture supernatants in a species-dependent manner, as revealed by semi-quantified mass spectrometric analysis and anion exchange chromatography analysis. Our data suggest that ovomucin potentially affects the gut microbiota through O-glycan decomposition by gut microbes and degradant sugar sharing within the community.

The present study investigated whether giving reality information and the category names of the to-be-learned materials affect incorporating of the materials into subject's preexisting knowledge. Forty university students were instructed that they were to learn real facts, while 43 university students were instructed that they were to learn rtificial facts. Actually, the subjects in both groups learned unfamilliar real facts. Half of the materials consisted of category names with two attributes, and the remaining half consisted of three attributes. Immediately following the learning phase, the subjects received a recall test, a recognition test, and a matching test. They were given the tests again after 1-week interval. The results indicated that giving real information and/or providing category names facilitated the learning of the materials. These results were discussed in terms of incorporation process of new information into preexisting knowledge.

In the Great East Japan Earthquake, we clarified that Ohtanabe fishing ports have fully function as tsunami mitigation using tsunami simulation. The process in which tsunami develops or propagates is very different depending on the presence or absence of the fishing ports. Especially, if there were not the fishing ports, the tsunami height increases more than 60% at the front of Ohtanabe seawall and the inundation height increases twice at the area inside the seawall. Furthermore, there will be also strongly possibility that the large amount of water is stored within the seawall for a long stretch of time. Therefore, we learned from the disaster that a multilayered defense system should be built to minimize damage in the event of a disaster that overwhelms disaster prevention infrastructures.
