Japan is the only country to suffer twice from the terrible consequences of atomic bombs. Hiroshima and Nagasaki are renowned internationally for experiencing the first twin devastating nuclear attacks in history. Unfortunately, Japan has witnessed several other serious nuclear‐related disasters in recent years. The much‐publicized Fukushima disaster in 2011 is one of them. How could such a serious accident occur in a modern, highly sensitive, nuclear‐conscious country?, The answer to that central question is complex, involving not only political and administrative issues but also technical and human dimensions. In retrospect, both government officials and private industry were far too lax with the operation and development of nuclear policies and facilities. The Fukushima debacle was the result of a lack of rigorous management and control of nuclear issues by both public authorities and private industry. 相似文献

To construct a system for identifying individual horses from urine samples that are submitted for postracing doping tests, we developed a genotyping assay based on 26‐plex single‐nucleotide polymorphisms (SNPs). DNA was isolated from urine using a commercially available DNA/RNA extraction kit, and SNP genotyping was achieved with a SNaPshot? technique. DNA profiles including 26 SNPs were acquired from urine samples and blood/hair samples. Within the studied Thoroughbred population, the 26‐plex assay showed a probability of identity of 5.80 × 10?11. Compared to the conventional short tandem repeat assay, the SNP assay used less DNA, and the rate of successful genotyping was improved to 97% using aliquots of horse urine as small as 140 μL. The urinary DNA could be successfully genotyped under proper storage concerning refrigeration or freeze–thawing. This SNP assay can be used for individual identification when suspicious results are obtained from horse doping tests. 相似文献

A procedure has been developed to extract and recover minute amounts of delta-9-carboxytetrahydrocannabinol (THC-COOH) from urine. A new non-isotopic internal standard is introduced to permit a chromatographic assay of the metabolite. The method affords a 91% recovery of 20 ng/mL of the THC-COOH acid from spiked urine with the assurance of a 3.8% coefficient of variation. 相似文献

Hydromorphone detected in bile following hydrocodone ingestion 总被引:1,自引:0,他引:1
Two similar cases are reported here in which Tussionex, a preparation containing hydrocodone and phenyltoloxamine, caused or contributed to death. Toxicological analyses revealed a high concentration ratio of hydromorphone to hydrocodone in the bile in both cases. It is postulated that the finding of hydromorphone is due to the metabolism of hydrocodone. 相似文献

Nozomi Idota M.D. Mami Nakamura M.D. Koji Masui M.D. Yasuhiro Kakiuchi M.D. Kei Yamada M.D. Hiroshi Ikegaya M.D. 《Journal of forensic sciences》2017,62(2):536-540
We report here lessons learned from an autopsy case involving radioactive materials. We performed an autopsy of an unidentified mummified man with no available medical history whom from imaging findings we suspected had received radioactive seed implants for prostate brachytherapy. We returned the excised prostate and seeds to the body. A few days later, the body was identified by DNA matching and cremated. According to the man's medical record, he had undergone iodine‐125 seeds implantation for prostate cancer 11 months earlier. We should have removed the radioactive seeds from the body to prevent radiation exposure to the bereaved family and/or environmental pollution due to cremation. Surprisingly, one seed was found in the stored prostate specimen. Forensic experts should be cognizant of the risk of both radiation exposure in the autopsy room and environmental pollution. We must remain abreast of the latest advances in medicine. 相似文献

Allele frequencies for the nine short tandem repeat (STR) loci D3S1358, vWA, FGA, TH01, TPOX, CSF1PO, D5S818, D13S317, and D7S820 were investigated in 195 unrelated Ovambo (Bantus) population from Namibia. AmpFlSTR Profiler Kit was employed for amplification. For each locus, 6-19 alleles were observed. Comparison between Ovambo population data and that of other African populations was performed. AmpFlSTR Profiler detection system is a useful tool for individual identification in Ovambo population. 相似文献

A previously healthy 9-year-old Japanese boy with a 4-day history of vomiting and headache died suddenly and unexpectedly. An external examination revealed no abnormalities other than foam around the mouth and nose. An internal examination revealed severe pulmonary edema and hemorrhagic hemangiopericytoma arising from the choroid plexus of the right lateral ventricle. The cause of death was thought to be neurogenic pulmonary edema caused by the rapid growth of a hemangiopericytoma, with intratumoral hemorrhage. 相似文献

A 28-year-old male methamphetamine abuser, who had been buried for 5 years after being killed by strangulation, was found skeletonized. Methamphetamine and amphetamine in the significantly denatured fatty material of the bone marrow were analyzed by gas chromatography and gas chromatography-mass spectrometry. The confirmation of the chemicals was carried out by chemical ionization (CI) mass chromatography, CI mass spectrometry and CI mass fragmentography. The concentrations of methamphetamine and amphetamine determined by CI mass fragmentography were 1.0 mumol/100 g and 0.1 mumol/100 g, respectively. The method used would seem to be very useful for determination of methamphetamine and amphetamine in marked putrefied biological materials. 相似文献

During the autopsy of heroin users, the most consistent morphologic finding is the enlargement of hepatic lymph nodes. Nodes from seven heroin addicts were analyzed for morphine and a concentration range of 0.02 to 0.87 mg/100 g was found. Morphine was detected in all of the nodes examined and the concentration was generally higher than that in the blood. 相似文献
