Since radiation accidents, particularly nuclear disasters, are rarer than other types of disasters, a comprehensive radiation disaster medical curriculum for them is currently unavailable. The Fukushima compound disaster has urged the establishment of a new medical curriculum in preparation for any future complex disaster. The medical education will aim to aid decision making on various health risks for workers, vulnerable people, and residents addressing each phase in the disaster. Herein, we introduce 3 novel educational programs that have been initiated to provide students, professionals, and leaders with the knowledge of and skills to elude the social consequences of complex nuclear disasters...

Perlman syndrome is a rare overgrowth syndrome characterized by polyhydramnios, macrosomia, distinctive facial appearance, renal dysplasia, and a predisposition to Wilms' tumor. The syndrome is often associated with a high neonatal mortality rate and there are few reports of long-term survivors. We studied a 6-year-old Japanese female patient, who was diagnosed with Perlman syndrome, with novel compound heterozygous mutations in DIS3L2 (c.[367-2A > G];[1328T > A]), who has survived long term. Most reported DIS3L2 mutations have been the homozygous deletion of exon 6 or exon 9, and these mutations would certainly have caused the loss of both RNA binding and degradation activity...

Radioprotective agents have been developed to protect patients against the damaging and lethal effects of ionizing radiation. However, in addition to the intrinsic ability to target reactive oxygen species (ROS), the ability to retain a significant level of bioavailability is desirable in radioprotective agents because that would increase and prolong their radioprotective efficacy and improve its safety. Here, we report the development of a novel nanoparticle-based radioprotective agent with improved bioavailability, which suppressed the adverse effects typically associated with low-molecular-weight (LMW) antioxidants...

This is the third analysis of solid cancer incidence among the Life Span Study (LSS) cohort of atomic bomb survivors in Hiroshima and Nagasaki, adding eleven years of follow-up data since the previously reported analysis. For this analysis, several changes and improvements were implemented, including updated dose estimates (DS02R1) and adjustment for smoking. Here, we focus on all solid cancers in aggregate. The eligible cohort included 105,444 subjects who were alive and had no known history of cancer at the start of follow-up...

With advances of combined modality therapy, prognoses in esophageal cancer have been improving. After resection of esophageal cancer, the development of gastric tube cancer is a risk. While such cancer in an early stage can be cured endoscopically, total gastric tube resection is indicated in advanced stages. A 68-year-old man underwent subtotal esophagectomy reconstructed with a gastric tube through the retrosternal route. Gastric cancer was found one and a half years postoperatively. The gastric tube was resected without sternotomy...

Influenza viruses have acquired resistance to approved neuraminidase-targeting drugs, increasing the need for new drug targets for the development of novel anti-influenza drugs. Nucleoprotein (NP) is an attractive target since it has an indispensable role in virus replication and its amino acid sequence is well conserved. In this study, we aimed to identify new inhibitors of the NP using a structure-based drug discovery algorithm, named Nagasaki University Docking Engine (NUDE), which has been established especially for the Destination for GPU Intensive Machine (DEGIMA) supercomputer...

Anionic and neutral fullerene derivatives were dissolved in water by β-(1,3-1,6)-D-glucan (β-1,3-glucan) as a solubilizing agent. In the water-solubilized complexes, the concentrations of fullerene derivatives were ca. 0.30 mM and the average particle sizes were ca. 90 nm. The β-1,3-glucan complexed fullerene derivative with a carboxylic acid was found to have higher photodynamic activity toward macrophages under visible-light irradiation (λ > 610 nm) when compared with that of other β-1,3-glucan-complexed fullerene derivatives...

Neuroblastoma is a childhood malignancy originating from the sympathetic nervous system and accounts for approximately 15% of all pediatric cancer-related deaths. To newly identify gene(s) implicated in the progression of neuroblastoma, we investigated aberrantly methylated genomic regions in mouse skin tumors. Previously, we reported that TFAP2E, a member of activator protein-2 transcription factor family, is highly methylated within its intron and its expression is strongly suppressed in mouse skin tumors compared with the normal skin...

REVIEW
Tadao Nagasaki, Hisako Matsumoto, Kenji Izuhara
Type-2/eosinophilic inflammation plays a pivotal role in asthma. The identification of severe type-2/eosinophilic asthma is important for improving the management of patients with asthma. Therefore, efforts to develop non-invasive biomarkers for type-2/eosinophilic airway inflammation have been made during this decade. Currently, fraction of exhaled nitric oxide (FeNO) and serum periostin levels are considered markers of type-2/eosinophilic inflammation in asthma. However, a single-marker approach has limited the ability to diagnose severe type-2/eosinophilic asthma accurately and predict disease outcomes precisely...

Trimeric autotransporters are surface-exposed proteins of Gram-negative bacteria belonging to the type V secretion system. They are involved in virulence and are targets for vaccine and diagnostic tool development, so optimal systems for their expression and purification are required. In the present study, the impact of the extended leader peptide of the Haemophilus parasuis virulence-associated trimeric autotransporters (VtaA) in its production as recombinant proteins in Escherichia coli was evaluated. The 13 genes encoding the VtaA1 to VtaA13 passenger domains of the strain Nagasaki were cloned in the pASK-IBA33plus plasmid and expressed in E...

BACKGROUND: Handgrip strength is a simple measurement of overall muscular strength and is used to detect sarcopenia. It also predicts adverse events in later life. Many mechanisms of sarcopenia development have been reported. A hypertensive status impairs endothelial dysfunction, which might deteriorate skeletal muscle if vascular angiogenesis is not maintained. OBJECTIVES: This study investigated muscle strength and circulating CD34-positive cells as a marker of vascular angiogenesis...

BACKGROUND AND PURPOSE: Although the incidence of living donor death is low in Japan, statistics show one living liver donor death in more than 7000 living liver transplants. Thus, medical transplant personnel must recognize that the death of a living organ or tissue transplant donor can occur and develop an appropriate risk management program. METHODS AND RESULTS: We describe how Nagasaki University Hospital established and implemented a Donor Advocacy Team (DAT) program: a risk management program for initiation in the event of serious, persistent, or fatal impairment of an organ, tissue, or cell transplantation from a living donor...

There were two sources of ionizing irradiation after the atomic bombings of Hiroshima and Nagasaki: (1) initial gamma-neutron irradiation at the moment of detonation and (2) residual radioactivity. Residual radioactivity consisted of two components: radioactive fallout containing fission products, including radioactive fissile materials from nuclear device, and neutron-activated radioisotopes from materials on the ground. The dosimetry systems DS86 and DS02 were mainly devoted to the assessment of initial radiation exposure to neutrons and gamma rays, while only brief considerations were given for the estimation of doses caused by residual radiation exposure...

RATIONALE: Chronic cough hypersensitivity, a potentially important concept of chronic or prolonged cough, is featured by heightened cough response to low-intensity stimuli, which may be generated in the absence of airflow limitations or allergic conditions. However, there is little epidemiological evidence to support this. OBJECTIVES: In this large-scale community survey, we aimed to determine risks and cough-aggravating factors of prolonged cough, while focusing on serum IgE levels...

To fully understand the radiation effects of the atomic bombing of Hiroshima and Nagasaki among the survivors, radiation from neutron-induced radioisotopes in soil and other materials should be considered in addition to the initial radiation directly received from the bombs. This might be important for evaluating the radiation risks to the people who moved to these cities soon after the detonations and probably inhaled activated radioactive "dust." Manganese-56 is known to be one of the dominant radioisotopes produced in soil by neutrons...

[70]Fullerene was dissolved in water by complexation with β-1,3-glucan using a mechanochemical high-speed vibration milling apparatus. The photodynamic activity of β-1,3-glucan-complexed C70 was highly dependent on the expression level of dectin-1 on the cell surfaces of macrophages. The photodynamic activity increased as a result of a synergistic effect between β-1,3-glucan-complexed 1'-acetoxychavicol acetate and the C70 complex.
