TL;DR: A cell line of Madin-Darby canine kidney cells persistently infected with human influenza A virus has been established and designated as MDCK-IVpi cells, and a certain fetuin-like substance in FCS might be responsible for the observed inhibition of virus replication.
Abstract: A cell line of Madin-Darby canine kidney (MDCK) cells persistently infected with human influenza A virus has been established and designated as MDCK-IVpi cells. Production of progeny virus in MDCK-IVpi cells was suppressed when the cells were incubated in the presence of 10% fetal calf serum (FCS). FCS impaired virus mRNA synthesis in MDCK-IVpi cells, which resulted in a scarcity of virus proteins for virion formation. However, MDCK-IVpi cells well supported the growth of superinfecting heterologous influenza viruses, even in the presence of FCS. A certain fetuin-like substance in FCS might be responsible for the observed inhibition of virus replication.

TL;DR: The commercially available phase contrast imaging system based on a photostimulable phosphor plate designed for mammography can provide breast images with details that are not available in conventional mammograms and would be useful to detect diseases in mammograms without any increase of exposure dose.
Abstract: X-ray beams irradiated from an x-ray tube with a point source or a sufficiently small focal spot produce edge-enhanced images in the boundary of an object due to the effect of phase shift of x-rays. This technique is called phase contrast imaging. A digital phase contrast imaging system based on a photostimulable phosphor plate (imaging plate) designed for mammography has been developed for clinical use recently and now commercially available. In this study, the digital phase contrast images of an acrylic plate and plant seeds were acquired without any increase of incident dose to detector when compared to conventional contact digital imaging. Improvement of image edge sharpness was evaluated in terms of spatial edge response and spectral analysis of the images. In addition, the improvement of the sharpness of the image was also evaluated in clinical mammograms. Our results indicated that higher image sharpness in the boundary of the object was observed. The power spectrum of the digital phase contrast image was found to be higher than that of the digital contact image at wide spatial frequency region. In conclusion, the commercially available phase contrast imaging system can provide breast images with details that are not available in conventional mammograms. The digital phase contrast imaging would be useful to detect diseases, especially microcalcifications, in mammograms without any increase of exposure dose.

TL;DR: People with schizophrenia converse with a robot regardless of whether the robot is talkative or not, and differences in the participants’ impressions of the robot depending on how talkative the robot was.
Abstract: Medication is an important approach of treatment for patients with schizophrenia; however, the availability of visiting nurses and other human-related support is limited. This study aims to build a system in which service robots support the treatment of individuals with schizophrenia with medication at home. Moreover, medical staff can seamlessly monitor the status of their patients through the robots using this system. In this study, to develop a support system, interactions between a communication robot and patients were surveyed, with a focus on the patients’ impression of the robot and actual utterance times. Communication between a commercially available communication robot and schizophrenic patients was investigated, particularly the participants’ feelings about the robot. In addition, the utterance data between the participants and the robot were extracted and the durations of the conversations were assessed. The examined interaction mode of a robot (talkative or not talkative) and whether the participant spoke or not (spoke or did not speak) revealed no significant association in all adjectives. A co-occurrence network graph showed differences in the participants’ impressions of the robot depending on how talkative the robot was. That is, when the robot did not initiate conversation often, the patient was more likely to initiate interactions and use longer phrases than when the robot initiated conversation frequently. Conversations also lasted longer when the participant, not the robot, initiated conversation. People with schizophrenia converse with a robot regardless of whether the robot is talkative or not. Since the content of the conversation was not analyzed qualitatively, it is necessary to carefully examine whether people with schizophrenia can develop partnerships with robots.

TL;DR: In this paper, a novel sum-peak method was developed to measure samples containing multiple radionuclides, where the peak count rates and the sum peak count rate were derived by modifying the conventional sum peak method, and the new method was theoretically verified and experimentally investigated using 60 Co and 22 Na.
Abstract: A novel sum-peak method was developed to measure samples containing multiple radionuclides. The conventional sum-peak method is one of the absolute radioactivity measurement methods for radionuclides emitting more than one photon in coincidence. The method requires the knowledge of the total count rate as well as the peak count rates and the sum peak count rate. If there are other radionuclides in a sample, it is fraught with difficulty to estimate the total count rate of the nuclide of interest. To solve the problem, a novel calculation method solely using the peak count rates and the sum peak count rate was developed by modifying the conventional sum-peak method. The new method was theoretically verified and experimentally investigated using 60 Co and 22 Na, and was successfully confirmed. It was proved that the modified sum-peak method is effective to measure samples with multiple radionuclides and is quite simple and practical.

TL;DR: In this paper, the authors examined the effects of two features of electronic negotiation, correctability and exitability, on negotiation processes and outcomes, and found that increasing the correctability of messages enhanced their clarity and generated more trade-offs, thus leading to more frequent agreements.
Abstract: The purpose of the present study was to examine via a laboratory experiment the effects of two features of electronic negotiation, correctability and exitability, on negotiation processes and outcomes. We define correctability as the negotiator's ability to revise messages before transmitting them to the other party, thus prompting informational and social elaboration. The opportunity to exit the negotiation that the use of the electronic medium creates, a phenomenon for which we have coined the term “exitability,” can give rise to the perception that electronic negotiation is inherently more unstable than face-to-face negotiation. In two experiments, we manipulated the exitability of one of the parties in three ways. In another experiment, we manipulated correctability in two ways. We found that increased exitability caused by the existence of a potential alternative party with whom to negotiate prompted participants to decrease their demands and to reach agreement more often. Increasing the correctability of messages enhanced their clarity and generated more trade-offs, thus leading to more frequent agreements.
