Joji M Otaki, Wataru Taira
Adverse biological impacts of the Fukushima nuclear accident have been revealed using the pale grass blue butterfly, Zizeeria maha, since 2012, which were often considered incompatible with the conventional understanding of radiation biology. This discrepancy likely originates from different system conditions and methodologies. In this article, we first respond to comments from the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) regarding our study; "technical errors" in unit usage and mathematical models noted by UNSCEAR are not errors but reflect our research philosophy not to introduce theoretical assumptions associated with unit conversion and mathematical fit...

PURPOSE OF REVIEW: This article describes the debates in Japan regarding the 100 mSv threshold assumption and ethical issues related to it, and explores the background to distorted risk information and absence of risk communication in Japan. Then we seek proper risk communication based on scientific evidence. RECENT FINDINGS: On March 11, 2011 an accident occurred at the Fukushima Daiichi Nuclear Power Plant due to the Great East Japan Earthquake. Since then a number of misunderstandings have become common in Japan as a result of public statements by the Japanese and local governments that have no basis in medical science or are contradictory to medical science...

AIM: The most frequent recurrence site of papillary thyroid carcinoma (PTC) is the cervical lymph nodes. The introduction of an electric linear probe for use with ultrasonography in 1996 improved preoperative lateral neck evaluations. Before 2006, however, our hospital routinely performed prophylactic modified neck dissection (p-MND) for N0 or N1a PTCs >1 cm to prevent node recurrence. In 2006, we changed our policy and the indications for p-MND to PTCs >3 cm and/or with significant extrathyroid extension...

BACKGROUND: Socioeconomic status (SES) and lifestyle-related factors are determinants of subjective health. However, changes in SES are inevitable in times of natural disaster, while lifestyle-related factors remain modifiable. The aim of this study was to use a cross-sectional approach to examine lifestyle-related factors that may attenuate the negative impact of disaster-induced changes in SES on poor subjective health. METHODS: We analyzed 33,350 men and women aged 20-64 years who were living in evacuation zones due to the radiation accident in Fukushima, Japan...

BACKGROUND: Synovial membrane inflammation is the most common finding presenting during hip arthroscopy, and may play a role in hip pain. We sought to determine the relationships between synovial cytokine levels, hip pain, and arthroscopic findings of the hip joint. METHODS: We prospectively included 33 patients who underwent arthroscopic hip surgery (34 hips). For all patients, radiographs and severity of pain were evaluated preoperatively. During arthroscopy, we classified the chondral injury and synovitis, noted the incidence of labral tear and its instability, and a sample of the synovial membrane was harvested for quantitative PCR to determine levels of TNFα, IL1β, IL6, ADAMTS4, MMP1, and MMP3...

BACKGROUND AND AIMS: Several studies have indicated that cisplatin (cis-diamminedichloroplatinum II; CDDP) causes urinary excretion of L-carnitine (LC). However, the underlying cofactors affecting the increased urinary excretion remain unclear. The present study was performed to evaluate the dynamics of LC in plasma and urine after CDDP chemotherapy and to examine the relations with clinical parameters, such as gender, body mass index (BMI), and renal function. METHODS: Twenty-two patients treated with CDDP therapy were selected...

Inhibition of transforming growth factor (TGF)-β1 signaling may be one of the most reliable approaches to treat skin fibrosis of scleroderma. Although there have been a lot of basic researches of TGF-β blockade reagents, few of them was proved to have inhibitory effects on fibrosis both in vitro and in vivo. In the present study, we randomly chose four commercially available low molecular compounds (Repsox, LY2109761, LY364947, and K02288) from TGF-β1 inhibitor library, and compared their anti-fibrotic effects in vitro and in vivo...

REVIEW
Shunji Fukushima
There are very little controversies on occlusion in healthy individuals, where centric relation is regarded as the criterion for assessing the present occlusion and also for establishing a new occlusal relationship between the upper and the lower jaws. On the other hand, the occlusal position in patients with deformed condyles still remains to be clarified. In this review, the effectiveness and limits of centric relation in these patients are discussed. In addition, the muscle induced occlusal positions, such as the muscular position and the terminal positions of habitual closing movements, are suggested as a substitution for centric relation...

BACKGROUND: On 11 March 2011, the Great East Japan Earthquake, followed by a tsunami and nuclear-reactor meltdowns, produced one of the most severe disasters in the history of Japan. The adverse impact of this 'triple disaster' on the health of local populations and the health system was substantial. In this study we examine population-level health indicator changes that accompanied the disaster, and discuss options for re-designing Fukushima's health system, and by extension that of Japan, to enhance its responsiveness and resilience to current and future shocks...

Following Japan's 2011 Fukushima nuclear incident, we assessed voluntary-based monitoring behavior in Minamisoma City-located 10-40 km from the Fukushima nuclear plant-to inform future monitoring strategies. The monitoring in Minamisoma included occasional free of charge internal-radiation-exposure measurements. Out of around 70,000 individuals residing in the city before the incident, a total of 45,788 residents (female: 52.1%) aged ≥21 were evaluated. The monitoring prevalence in 2011-2012 was only 30.2%, and this decreased to 17...

We developed a food web-based transfer factor (TFweb) to study contaminant movements from multiple prey items to a predator based on the dietary contributions of prey items with their respective contamination levels. TFweb was used to evaluate the transfer of (137)Cs into whitespotted char (Salvelinus leucomaenis) from the trophic structure of a stream-riparian ecosystem in headwater streams draining a Japanese cedar forest. We also examined the applicability of this method by comparing sites with different contamination levels but similar surrounding environments in Fukushima and Gunma...
