BACKGROUND Spermatogonia are highly tolerant to reactive oxygen species (ROS) attack while advanced-stage germ cells such as spermatozoa are much more susceptible, but the precise reason for this variation in ROS tolerance remains unknown. METHODOLOGY/PRINCIPAL FINDINGS Using the Japanese eel testicular culture system that enables a complete(More)
We are designing an application framework for creating graphics contents that utilize a multi-display environment. The processes store and exchange the geometry and event information via a shared space. We use a sensor to detect the placement of the displays. This enables the environment to change the number and layout of its displays dynamically.
The authors propose the use of a pinching gesture for relating the applications running on discrete mobile devices. The gesture is realized by swiping the touch-screen of two annexed mobile devices as if pinching them together. The authors believe that this user interface can create new user experiences of multiple-screen usages, especially by designing the(More)
We designed and built a system that configures the information of how displays are arranged as a multi-display environment. The system automatically matches the physical location of displays and network addresses. It uses a web camera for capturing a real-time video to observe each display to flash its screens one by one. The timing and relative locations(More)
BACKGROUND Recent technological advances have stimulated the development of endoscopic optical biopsy technologies. This study compared the accuracy of endoscopic diagnosis using magnifying narrow-band imaging (NBI) and histologic diagnosis of esophageal squamous lesions. METHODS Patients at high risk for esophageal squamous cell carcinoma were examined(More)
We developed MovieTile, a system for constructing multi-display environments using multiple mobile devices. The system offers a simple and intuitive interface for configuring a display arrangement. It enables the use of devices of different screen sizes mixed in forming a single virtual screen of free shape. The system delivers a movie file to all devices,(More)
A novel water-soluble polysaccharide was identified in the pupae of the melon fly (Bactrocera cucurbitae) as a molecule that activates the mammalian innate immune response. We attempted to purify this innate immune activator using nitric oxide (NO) production in mouse RAW264 macrophages as an indicator of immunostimulatory activity. A novel acidic(More)
