Abstract Background: Recent molecular biological studies have revealed that chromosomal instability (CIN) promotes the malignant phenotype of tumors. CIN causes segregation errors, leading to micronuclei (MN) formation. Ruptured MNs activate cGAS-STING pathway, an intracellular DNA sensor, and induce metastasis invasion. Histological confirmation is thought be uncertain not reproducible. On other hand, cGAS localized in a subset MN by immunohistochemistry, so we attempted apply cGAS-positive...

In order to slice the larger size ingot toward 6 inch of silicon carbide (SiC), we are developing Multi-wire Electric Discharge Machining (EDM). To prevent wire break during slicing, have developed electric discharge pulse control system. So far, with 10 multi-wires, succeeded in slicing 4 SiC balk single crystal without break. High quality surface (e.g. small value around μm SORI for 3 inchi wafer) was also achieved. By polishing methode, EDM-sliced wafer estimated uniform thickness damaged...

One of the most important lessons learned from Fukushima Daiichi Nuclear Power Plant accident is that direct (in vivo) measurements thyroid exposure to radioiodine (mainly, 131I) in affected populations should be initiated a timely manner. Furthermore, existing commercial detectors are not necessarily suitable for measurement young children, who especially vulnerable radiation and therefore screen. This paper presents development new monitor such results phantom-based experiments. The has...

After a nuclear accident, population monitoring is necessary to determine the radiation exposure levels of affected population. One components direct thyroid measurements assess internal dose (mainly from 131I with relatively short physical half-life: 8.02 days). These are particularly important for young children but were not adequately performed after 2011 Fukushima Daiichi Nuclear Power Plant (FDNPP) accident. Herein we propose feasible and robust method obtain as much reliable human data...
