    We examined nests and other traces of moles in Ashiu, Kyoto, beneath fruit bodies of a mushroom species, Hebeloma radicosum, which grows on the underground latrines of small mammals. We also attempted to catch animals at nesting sites which were detected through the fungal fruiting. As a result, an adult specimen of a talpine mole species, Euroscaptor mizura, was collected together with its nest. This is the first record of E. mizura from Ashiu region. Also, this is the first report of the nest of E. mizura, of the mushroom-mole nest association in H. radicosum and E. mizura, and of the capture of a mole at the nesting site under indication of the fungus. Morphological features of the animal and structure of the nest are described. This finding further revealed a contiguousness in the distribution of three talpine species, E. mizura, Mogera wogura and Mogera kobeae in Ashiu

    Development of the sensor and actuator node device for an autonomous ATV

    This paper addresses the development of sensor and actuator node device for an autonomous All Terrain Vehicle (ATV). Generally, the present field survey activities are performed by manual labors. The range of the field survey tends to be vast; therefore a lot of labors are needed. To realize the investigation of the environment with less manned labors, we add the functionality for automation to the ATV. In this paper, we introduce the CAN bus network to the autonomous ATV for the distributed control system, and construct the steering angle control system of the ATV and evaluated it.特集 : Special Section for the Papers Presented at the Symposium on Mechanical Engineering, Industrial Engineering, and Robotics held at Noboribetsu, Hokkaido, Japan on 11 - 12 January 201

    Resurrection of a Bull by Cloning from Organs Frozen without Cryoprotectant in a −80°C Freezer for a Decade

    Frozen animal tissues without cryoprotectant have been thought to be inappropriate for use as a nuclear donor for somatic cell nuclear transfer (SCNT). We report the cloning of a bull using cells retrieved from testicles that had been taken from a dead animal and frozen without cryoprotectant in a −80°C freezer for 10 years. We obtained live cells from defrosted pieces of the spermatic cords of frozen testicles. The cells proliferated actively in culture and were apparently normal. We transferred 16 SCNT embryos from these cells into 16 synchronized recipient animals. We obtained five pregnancies and four cloned calves developed to term. Our results indicate that complete genome sets are maintained in mammalian organs even after long-term frozen-storage without cryoprotectant, and that live clones can be produced from the recovered cells

    Identification of Carnitine Transporter CT1 Binding Protein Lin-7 in Nervous System

    _L-Carnitine is an essential component of mitochondrial fatty acid b-oxidation in the muscle and may control the acetyl moiety levels in the brain for acetylcholine synthesis. Carnitine transporter 1(CT1)is the high affinity _L-carnitine transporter whose localization was observed in the kidney, testis, liver, skeletal muscle and brain. To clarify the molecular mechanism of carnitine transport, we sought to find the interacting protein that may be related to the transport function of CT1. Using the intracellular C-terminal region of rat CT1 containing PDZ(PSD95/DLG/ZO-1)motif as bait, we performed the yeast two-hybrid screening against rat brain cDNA library. Thirty two positive clones were obtained from the 2.7×10^7 clones screened. One of them was PDZ domain-containing protein Lin-7. We found that Lin-7 interacts specifically with C-termini of CT1:deletion and mutation of the CT1 C-terminal PDZ-motif abolished the interaction with Lin-7 in the yeast two-hybrid assay. In addition, a PDZ domain within Lin-7 associates with the CT1 C-terminal. The association of CT1 with Lin-7 enhanced _L-carnitine transport activities in HEK293 cells although there is no statistical significance. Coexpression of Lin-7 and CT1 is identified in motor neurons of the spinal cord ventral horn together with Lin-2, a binding partner of Lin-7 known to assemble proteins involved in synaptic vesicle exocytosis and synaptic junctions. Therefore, Lin-7 interacts with CT1 and may regulate their subcellular distribution or function in central nervous system

    Feasibility of Exploiting Celution^<TM> System in Autologous Cell Therapy in Dokkyo Medical University Hospital:Safety and Reproducibility

    Get PDF
    In 2012, we established the Center for Regenerative Medicine in Dokkyo Medical University Hospital, and are now preparing the necessary equipment and preclinical evidence for cell therapy. Liposuction is a commonly used procedure in plastic surgery and the lipoaspirate is discarded as a medical waste. However, the lipoaspirate is known to contain abundant mesenchymal stem cells, and thus, it is currently one of the most feasible options of regenerative medicine. Several ongoing clinical trials of cell therapy (in Japan and overseas as well) are based on the Celution^ system, an automated cell-processing machine utilizing lipoaspirate. The merit of using such a machine is that collected cells are so abundant that it is not necessary to expand the cell number in a Cell Processing Center. Moreover, there are fewer risks of bacterial infection because the system is isolated from the ambient dust and operated automatically. Our group is now planning respective cell therapies for breast reconstruction after mastectomy, urinary incontinence and ischemic cardiovascular diseases, and all these protocols will be based on the Celution^ system. Here, we report the initial test run of Celution^ to confirm its safety and reproducibility
