    Abstract Background Recently, endoscopic ultrasound‐guided gallbladder drainage has attracted much attention. However, the risk management of adverse events and techniques to avoid them are not yet mature. Difficulty dilating the fistula with a dilator or placing a stent for drainage often prolongs the procedure time, which increases the risk of peritonitis or the procedure failure rate. Therefore, the result of the procedure will be unstable, and one cause is the lack of adhesion between the gallbladder and the digestive tract walls. Methods We developed an anchor to fix the stomach and gallbladder walls prior to endoscopic ultrasound‐guided gallbladder drainage in four live pigs using the anchor. Results The stomach and gallbladder walls were fixed in three pigs, and technical success was achieved in all three pigs. In two pigs that were dissected 17 and 34 days post‐procedure, respectively, fixation occurred in one pig. In the other pig, anchoring of the gallbladder and stomach walls did not occur because the wings of the anchor in the gallbladder were damaged. Conclusions Although issues remain regarding efficacy and safety, we plan to make improvements in this novel device and aim for clinical application.

    Stainless steel plays an important role in industry due to its anti-corrosion characteristic. It is known, however, that local corrosion can damage stainless steel under certain conditions. In this study, we developed a novel measurement system to observe crevice corrosion, which is a local corrosion that occurs inside a narrow gap. In addition to pH imaging inside the crevice, another imaging technique using an infrared light was combined to simultaneously visualize surface roughening of the test piece. According to experimental results, the lowering of local pH propagated inside the crevice, and after that, the surface roughening started and expanded due to propagation of corrosion. The real-time measurement of the pH distribution and the surface roughness can be a powerful tool to investigate the crevice corrosion.

    Recently, robotic studies based on biological materials have been attracting a lot of attention, because of its intrinsic abilities. Biological materials have some interesting capabilities in such a way that tissues as devices can be self-organized, adaptable, self-repaired, and so on. Such significant abilities are based on cellular behavior that reflects mechanical stimuli during the development of the tissues. Under this circumstance, in this paper, we intend to deal with development of a micro-actuator by exploiting mechanical stimulus response of muscle cells. To do so, we carry out the induction of differentiation into myofilaments from a cultured myoblasts C2C12 under the periodic stretching forces for 70 hours. As a result, interestingly, we found that induction of differentiation into myofilament-like calls are promoted under the mechanical stimulus.

    A BCI (brain-computer interface) system that detects visual ERPs (event-related potentials) to control a cursor on the computer screen is proposed in this paper. The ERPs induced by the selective attention to one of the eight circles around the cursor which was blinked in random order, was used to control the cursor movement. Information bit rates for five subjects were about 11 to 16 bit/min. Improvement of an information bit rate and increasing a speed of cursor movement are left for further studies.

    To detect the imagined limb from EEG related to the motor imagery for the use in BCI, the spatial filter using neighboring channels was commonly used. But, the spatial filter has been selected mainly by the empirical method on trial-and-error basis. In this study, we recorded the EEG during left hand, right hand and feet motor imagery from five subjects and the ICA was applied to discovering the spatial filter for extracting event-related EEG components to the motor imagery. It was shown that the spatial filter can be generated semi-automatically by applying ICA to recorded multichannel EEG.

    In this study, the effect of neurofeedback training on brain activity during motor imagery was evaluated by functional magnetic resonance imaging (fMRI). The training was performed for 5 days using near-infrared spectroscopy (NIRS). During training sessions, feedback information was extracted from the brain activity which was measured online while users performed motor imagery of right hand. On 3 out of 5 subjects, brain activations at supplementary motor area (SMA), primary motor area (M1) and cerebellum were localized after training. Furthermore, analysis of BOLD signal in specific volume of interests (VOIs) showed that peak and integral values during motor imagery became smaller after training on 2 of these 3 subjects. In contrast, it was shown by our NIRS study that the integral values of oxy-hemoglobin signal measured by NIRS during motor imagery on these 3 subjects were increased after feedback training.

    The authors have evaluated the effect of neurofeedback training for subjects on the brain activity to be used in the brain-computer interface (BCI) which detected motor imagery from cerebrum blood flow measured by NIRS (near-infrared spectroscopy). The concentrations of oxy-hemoglobin on motor cortex during motor imagery of a subject's right hand were measured, and were visually fed back to the subject. It was shown that the training enhanced the cerebral blood flow during motor imagery on two out of five subjects. Investigation of more effective training and neurofeedback methods were left for the further study.

    A brain-computer interface (BCI) which detected motor imagery from cerebrum blood flow measured by NIRS (near-infrared spectroscopy) was constructed and the effect of online feedback training for subjects was evaluated. Concentrations of oxy-hemoglobin in motor cortex during motor imagery of subject's right hand was measured by 52 channel NIRS system, and mean magnitude of measured signal near C3 in international 10-20 system was visually fed back online to subject. It was shown that the signal-to-noise ratio of blood flow level elicited by imagery of subject's right hand was improved by online feedback training for five days. Investigation of the detailed effect of feedback training to the change of brain activities related to motor imagery was left for further study.

    This paper reviews our recent approaches for a label-free detection of protein-protein interactions which can perform simultaneous protein conformational analysis by using infrared absorption spectroscopy in the multiple internal reflection geometry (MIR-IRAS). Using this method, the target protein was detected in aqueous solution phase based on the peak height of the protein amide I and amide II bands, while discrimination of specific and nonspecific signals is made based on the secondary structure of the target protein. An antigen-antibody interaction on semiconductor surfaces was investigated as a model system, since it is well-known that antibodies largely consist of β-sheet structures. The features of our approach using MIR-IRAS combined with protein secondary structure analysis were discussed in terms of sensitivity, capability of quantitative analysis, and specific/nonspecific discrimination.

    An auditory brain-computer interface (BCI) which detected event-related potential (ERP) elicited by selective attention to one of the tone streams was proposed. Each tone in two kinds of auditory oddball sequences with different frequencies of standard tones was presented alternatively to subjects, and they were perceived by subjects as two kinds of segregated streams. Event-related potentials elicited by two kinds of deviant tones were classified by linear discriminant analysis (LDA) to find which streams subjects paid selective attention. By the experiments to six healthy subjects, it was shown that this system could achieve binary selection of two kinds of tone streams.

    A Brain-Computer Interface (BCI) is a communication system that translates brain activity into commands for controlling a computer or an external device for disabled users like amyotrophic lateral sclerosis (ALS) patients. We developed a BCI system using event-related potentials during selective attention to tone frequencies and a classification accuracy of detecting event-related potentials caused by two kinds of deviant stimulation with different frequencies was evaluated. A classification accuracy of 60〜90% and a classification rate of 3〜4bit/min were obtained respectively for two subjects.

    In this study, we investigated the effect of feedback training to the user to improve the accuracy of command detection on BCI system which detects a command from EEG during motor imagery. During the feedback training session, subjects were visually presented a white bar on LCD whose length was proportional to the EEG band power of the specific frequency range. The effects of feedback training were evaluated in terms of the change of the band power and the accuracy of command detection. It was shown that the feedback training was effective on two subjects out of four.

    A generic platform for realizing online brain-computer interface (BCI) system was developed. The platform is module-based, and has a GUI-based diagram editor for building desired system. The platform can be extended easily, and supports multiple acquisition hardware and operating system. An online BCI system that detects the band power of EEG beta oscillation during hand or foot motor imagery was built on this platform. We confirmed that the system was able to realize an online BCI system. The platform is extendable, and a various system can be realized by adding new modules.

    昨今、若年層のアレルギー症の増大が報告されており、深刻な社会問題になりつつある。その原因としては、我々の周囲を取り巻く多種多様の化学物質が考えられている。すでに周知の通り、これら化学物質は、アレルゲンまた環境ホルモンとして作用しうるため、新規化学物質の生体への影響を調べる簡易検査装置の重要性が増している。我々工学者は、社会に対するフィードバックとして、多くの人が抱える問題をサポートする手段となる装置・手法を提案し、実際に開発しなければならない。 モデル系として培養細胞を用いた評価法の中でも、経内皮電気抵抗測定(TER)は、薬物刺激による細胞密着性の変化(透過特性)を調べる面で有用であり、これまでに多くの報告が行われている。本研究では、この測定を半導体化学上において行うシステムを構築し、簡便性と集積性の向上を目指す。
