Several populations of wild Japanese macaques (Macaca fuscata) inhabit the area around Fukushima Daiichi Nuclear Power Plant (FNPP). To measure and control size these populations, are captured annually. Between May 2013 December 2014, we performed a haematological analysis within 40-km radius FNPP, location nuclear disaster two years post-accident. The dose-rate radiocaesium was estimated using ERICA Tool. median internal 7.6 μGy/day (ranging from 1.8 to 219 μGy/day) external 13.9 6.7 35.1...
Abstract Here we determined the 90 Sr concentrations in teeth of cattle abandoned evacuation area Fukushima-Daiichi Nuclear Power Plant (FNPP) accident. activity varied from 6–831 mBq (g Ca) −1 and exhibited a positive relationship with degree radioactive contamination that experienced. Even within an individual animal, specific (Bq Sr) ) depending on development stage during FNPP accident: were early high activities, while late low activities. These findings demonstrate is incorporated into...
As three-dimensional (3D) intraoral scans are becoming popular in modern dentistry, they also offer a new category of antemortem data for forensic identification. This study proposes novel methodology individual identification based on 3D homologous models the maxilla. Data from 100 maxillary plaster casts (40 monozygotic twin casts, 28 dizygotic and 32 singleton casts) were used. From initial sample, 10 randomly chosen duplicated four times, resulting 40 duplicates. These divided into...

Tohoku J. exp. Med., 1986, 148 (2), 197-205 - A 23 year old pregnant woman presented in her third trimester severe pancreatitis hyperlipidemia. Initial investigations suggested that was induced by profound hypertriglyceridemia, which the result of an underlying Fredrickson's V type hyperlipoproteinemia...
Abstract Background The assimilation between three-dimensional (3D) imaging techniques and dental forensic science can provide rich stable information for human identification. This study aimed to determine the effective number surfaces of teeth identification through 3D approach. Material methods In present study, maxillary casts were fabricated from subjects who met inclusion criteria scanned using a scanner Vivid 910. Rapidform XOS/SCAN software was used create trim point cloud data....
Kinship analysis was performed on a Jomon double burial from the Usu-Moshiri site in Hokkaido, Japan, using odontometric data conjunction with mitochondrial DNA data. Q-mode correlations respect to tooth crown measurements indicated low similarity between two adult female skeletons found this burial. Moreover, revealed that these individuals were not maternal relatives. Consequently, judging both morphological and genetic evidence, are more likely have been unrelated rather than...
Abstract The accident at the F ukushima D aiichi Nuclear Power Plant ( FNPP ) released a large amount of radioactive substances into environment. Furthermore, beef contaminated with cesium above 500 Bq/kg safety standard was circulated in food chain 2011. Japanese consumers remain concerned about radioactively food. In our previous study, we detected linear correlation between 137 C s) activity blood and muscle around to 2500 cattle. However, it unclear whether maintained lower radioactivity...
The Fukushima-Daiichi Nuclear Power Plant (FNPP) accident in March of 2011 released substantial amounts radionuclides into the environment. We collected 4,957 deciduous teeth formed children before Fukushima to obtain precise control data for after accident. Radioactivity was measured using imaging plates (IP) and epidemiologically assessed multivariate regression analysis. Additionally, we
The 2011 earthquake severely damaged the Fukushima Daiichi Nuclear Power Plant (FNPP), resulting in release of large quantities radioactive material into environment. deposition these radionuclides rice straw as livestock feed led to circulation contaminated beef market. Based on safety concern consumers, a reliable method for estimating concentrations cesium muscle tissue is needed. In this study, we analyzed blood and skeletal 88 cattle, detected linear correlation between them. We then...
Rapid analysis of <sup>90</sup>Sr in bone and tooth samples cattle was conducted by inductively coupled plasma mass spectrometry (ICP-MS). The ICP-MS method can be a rapid useful procedure for determination small samples.
Electron spin resonance (ESR) dosimetry is one of the most powerful tools for radiation dose reconstruction. The detection limit this technique using human teeth reported to be 56 mGy or 67 mGy; however, absorbed Fukushima residents after Daiichi Nuclear Power Plant (FNPP) accident was estimated lower than limit. Our aim assess children in Prefecture accident; therefore, it important estimate their teeth. enamel deciduous Japanese separated by mechanical method 115.0 mGy. density separation...
In an adult human skeleton of the Final Jomon age excavated at Nakazawahama shell-mound in Iwate Prefecture, northeastern Japan, grooved enamel defects (about 2 mm width) were observed circumferentially around dental crowns upper left central incisor, right lateral and canine. Observations crown surface using a stereomicroscope evaluations soft X-ray images revealed severe developmental (DDEs), having characteristics both hypoplasia hypocalcification caused by systemic metabolic stresses.
