This study examined the accumulation and tissue distribution of radioactive cesium nuclides in Japanese Black beef heifers raised on roughage contaminated with radioactive fallout due to the accident at the Fukushima Daiichi Nuclear Power Station on March 2011. Radiocesium feeding increased both 134Cs and 137Cs levels in all tissues tested. The kidney had the highest level and subcutaneous adipose had the lowest of radioactive cesium in the tissues. Different radioactive cesium levels were not found among parts of the muscles. These results indicate that radiocesium accumulated highly in the kidney and homogenously in the skeletal muscles in the heifers.

Background: The slow-flow phenomenon is associated with worse clinical outcomes after percutaneous coronary intervention (PCI), so our goal for this study was to see how predictive how near-infrared spectroscopy (NIRS) could be.Methods and Results: We enrolled 179 lesions from 152 patients who had de novo coronary stent implantation guided by NIRS-intravascular ultrasound (IVUS) (male: 69.1%, mean age: 74.3±11.5 years, acute coronary syndrome: 65.1%, diabetes: 42.1%). NIRS automatically determined the maximum 4-mm lipid core burden index (maxLCBI4 mm) value at pre- and post-PCI procedures. The slow-flow phenomenon was defined as the deterioration of TIMI (Thrombolysis in Myocardial Infarction) flows on angiography during the PCI procedure in the absence of mechanical obstruction. The slow-flow phenomenon occurred in 13 (7.3%) lesions, and the slow-flow phenomenon group had a significantly higher maxLCBI4 mm(740±147 vs. 471±223, P<0.001). The best maxLCBI4 mmcutoff point in both acute and chronic coronary syndrome was 578 and 480, with sensitivity of 100%, for predicting the slow-flow phenomenon. In the receiver-operating characteristics analysis, the area under the curve for acute and chronic coronary syndrome was 0.849 and 0.851, respectively.Conclusions: The results of this study support the utility of NIRS-IVUS-guided PCI for the prediction of the slow-flow phenomenon.

We established a DNA watermarking system for discriminating transgenic plants. The system contains an encryption algorithm based on a binary system, genetic transformation and a detection algorithm for encrypted DNA watermark sequences using a DNA dot plot. The encryption algorithm converted character strings into nucleic acid sequences through binary digits, and the sequence was designed to be resistant to transition mutations to decipher codes completely. Moreover, the encrypted sequences were capable of taking specific nucleotide sequences in using the algorithmic redundancy of the corresponding DNA. Genetic transformation enables labeling plant genomes with DNA watermarks. The detection algorithm allows finding traces of sequence changes in DNA watermarks, complementing the error protection function of the encryption algorithm. To validate the effectiveness of our DNA watermarking system, we introduced a DNA watermark to the tobacco genome and detected the DNA watermark in PCR products amplified from the genome. This indicates that DNA watermark technology is useful for introducing artificial genetic markers in plant organisms, in particular when several transgenic host plants and transgenes are used. The source codes of the Perl scripts are available in this report.
