This paper will examine deposition patterns of four radionuclides following the Fukushima-Daiichi accident. For nearly 13 d following the event, fission products were released into the environment through planned venting procedures and hydrogen explosions. To assist the government of Japan (GOJ) in the assessment of the releases, the National Nuclear Security Administration's Consequence Management Response Team (CMRT) deployed and took nearly 3 mo of measurements using airborne radiation sensors, fixed monitors, high purity germanium (HPGe) detectors, and health physics survey equipment...

BACKGROUND: Cisplatin is a key drug in lung cancer therapy. However, cisplatin is also well known to induce gastrointestinal disorders, such as chemotherapy-induced nausea and vomiting, anorexia, and weight loss. These symptoms sometimes affect patients' quality of life and make continuation of chemotherapy difficult. Anorexia is a cause of concern for patients with cancer because a persistent loss of appetite progresses to cancer cachexia. Although evidence-based management for chemotherapy has recently been established, there is room for improvement...

We aimed to monitor changes in the levels of amino acid neurotransmitters or neuromodulators simultaneously at the synaptic clefts of experimental animals. We developed a method for the simultaneous determination of the levels of amino acids, such as D-Ser, Gly, and L-Glu, which were involved in neurotransmission via the N-methyl-D-aspartate (NMDA) receptor, and other protein-constituted amino acids in a rat brain microdialysis (MD) sample. We used a liquid chromatography-mass spectrometry (LC-MS)/MS device equipped with a triazole-bonded column...

A 63-year-old female patient who had undergone cholecystectomy for inflammatory myofibroblastic tumor (IMT) in the gallbladder was referred to our hospital. The patient's disease relapsed, involving the pancreas, and was diagnosed as inoperable IMT 13 months after the cholecystectomy. The patient failed to respond to steroid and non-steroidal anti-inflammatory drug therapy, but subsequently exhibited a good response to vinorelbine and methotrexate combination chemotherapy. Little information is currently available on the efficacy of chemotherapy for adult-onset IMT...

This study aims to compare the outputs of the waist-worn Active style Pro HJA-350IT (ASP; used in studies with Asian populations), the waist-worn ActiGragh™GT3X+ using the normal filter (GT3X+) and the thigh-worn activPAL3 (AP) in assessing adults' sedentary behaviour (total sedentary time, number of breaks) under free-living conditions. Fifty healthy workers wore the three monitors simultaneously during their waking hours on two days, including a work day and a non-work day. Valid data were at least 10 hours of wearing time, and the differences between monitors on the sedentary outputs using the AP as criterion measurement were analyzed by ANOVA...

The pyrogallol red (PR)-based Cu(2+) complex was proven to be an effective and selective colorimetric chemosensing ensemble for recognition of oxalate over other anions in a perfect aqueous solution. The addition of oxalate to the PR-Cu(2+) complex resulted in a colour change from purple to orange colour due to the regeneration of PR by the chelation of oxalate with Cu(2+) , while other anions did not induce any significant colour change. Moreover, it was revealed that no obvious interference was observed during the titrations with oxalate into each other anion...

After the Fukushima Daiichi Nuclear Power Station (FDNPS) accident in 2011, aerial radiation monitoring (ARM) using a manned helicopter was conducted to rapidly measure air dose rates and the deposition of radioactive nuclides over a large area. Typically, the air dose rate is obtained by conversion from the count rate using conventional flat source model (FSM). The converted dose rate obtained via aerial monitoring poorly matches the results of ground measurement in the mountain and forest areas because FSM does not consider topographical effects...

A 63-year-old woman underwent thyroidectomy for papillary thyroid adenocarcinoma and cervical lymph node resection. Pathological analyses revealed the presence of signet cell carcinoma in a resected lymph node, which were apparently different from the pathological findings of thyroid carcinoma. No evidence of a primary tumor could be found elsewhere despite detailed examinations, including esophagogastroduodenoscopy, colonoscopy, capsule endoscopy, CT scan, and fluorodeoxyglucose-positron emission tomography...

BACKGROUND: Glucocorticoids play an important role in endocrine control. The association of glucocorticoid receptor (GR) gene polymorphisms with altered sensitivity to glucocorticoid therapy has been reported in adults. However, there are few such reports in infants. The present study analyzed the prevalence of four GR polymorphisms in preterm infants born before 30 weeks of gestation and determined the associations between these polymorphisms and clinical outcomes in the infants. METHODS: Totally, 41 preterm infants born at two hospitals in Fukushima were retrospectively screened for the presence of four GR gene polymorphisms, using a TaqMan single-nucleotide polymorphism genotyping assay...

Ecological risk assessment (ERA) is a powerful technical tool that can be used to analyze potential and extreme adverse environmental impacts. With the rapid development of nuclear power plants in coastal areas around the world, the establishment of approaches and methodologies for marine ERA with a focus on radiation accidents is an urgent requirement for marine environmental management. In this study, the approaches and methodologies for ERA pertaining to marine radiation accidents (MRA) are discussed and summarized with applications in case studies, such as the nuclear accident in Fukushima, Japan, and a hypothetical accident in Daya Bay, China...

BACKGROUND: Hepatitis A vaccination is recommended for travelers to endemic countries. Several inactivated aluminum-adsorbed hepatitis A vaccines are available worldwide, but only one licensed hepatitis A vaccine is available in Japan. This vaccine is a lyophilized inactivated aluminum-free hepatitis A vaccine (Aimmugen®). The standard schedule of Aimmugen® is three doses (at 0, 2-4 weeks, and 6 months). Japanese people will go abroad after receiving 2 doses of Aimmugen®. Some long-term travelers will receive the third dose of hepatitis A vaccine at their destination, at 6-24 months after 2 doses of Aimmugen®...

Introduction.Vibrio vulnificus (V. vulnificus) causes a severe infection that develops in the compromised host. Its pathophysiology is classified into three types: (1) primary septicaemia, (2) gastrointestinal illness pattern and (3) wound infection pattern. Of these, primary septicaemia is critical. V. vulnificus can be classified into three biotypes and two genotypes and its pathogenicity is type-dependent. Case presentation. A 47-year-old man presented to a local hospital with chief complaints of fever, bilateral lower limb pain and diarrhoea...

To understand the concentration and amount of Fukushima-derived Cs-137 in the ocean, this study simulated the oceanic dispersion of Cs-137 by atmospheric and oceanic dispersion simulations. The oceanic dispersion simulations were carried out with an oceanic dispersion model and multiple oceanic general circulation models. The Cs-137 concentrations were sensitive to ocean currents in the coastal, offshore, and open oceans. The mean Cs-137 concentrations of the multiple models relatively well agreed with the observed concentrations in the coastal and offshore oceans during the first few months after the Fukushima disaster, and in the open ocean during the first year after the disaster...

Subependymomas are slowly growing glial tumors, corresponding to WHO grade I. Few descriptions of the cytologic features of this neoplasm are available. This study describes the cytologic features of three subependymomas, as well as their differential diagnosis based on cytology. Three men, aged 52, 56, and 63 years, presented with headache. Magnetic resonance imaging revealed a nodular intraventricular mass in all three patients. Intraoperative squash cytology specimens from the three intraventricular tumors showed nodular clusters with microcystic changes...

Vertical profiles of radiocesium concentrations were measured in sediment cores collected at various times after the 2011 Fukushima nuclear accident in five Japanese lakes (Hinuma, Kasumigaura, Kitaura, Onogawa and Sohara) with different morphological and trophic characteristics in order to investigate the sedimentation-diffusion processes. In lakes where sediments had high porosities and experienced considerable wave action due to shallowness, we observed rapid penetration of radiocesium to a certain depth just after the accident, followed by downward movement of the peak depths...

OBJECTIVE: The 2011 Fukushima Daiichi nuclear accident was the worst nuclear disaster since Chernobyl. The Daiichi workers faced multiple stressors (workplace trauma, victim experiences, and public criticism deriving from their company's post-disaster management). Literatures suggest the importance of workplace interpersonal support (WIS) in enhancing psychological health among disaster workers. We sought to elucidate the role of their demographics, disaster-related experiences, and post-traumatic stress symptoms on perceived WIS...
