Abstract
A precise description of neutrino-nucleus reactions will play a key role in addressing fundamental questions such as the leptonic CP violation and the neutrino mass hierarchy through analyzing data from next-generation neutrino oscillation experiments. The neutrino energy relevant to the neutrino-nucleus reactions spans a broad range and, accordingly, the dominant reaction mechanism varies across the energy region from quasi-elastic scattering through nucleon resonance excitations to deep inelastic scattering. This corresponds to transitions of the effective degree of freedom for theoretical description from nucleons through meson-baryon to quarks. The main purpose of this review is to report our recent efforts towards a unified description of the neutrino-nucleus reactions over the wide energy range; recent overall progress in the field is also sketched. Starting with an overview of the current status of neutrino-nucleus scattering experiments, we formulate the cross section to be commonly used for the reactions over all the energy regions. A description of the neutrino-nucleon reactions follows and, in particular, a dynamical coupled-channels model for meson productions in and beyond the [Formula: see text](1232) region is discussed in detail. We then discuss the neutrino-nucleus reactions, putting emphasis on our theoretical approaches. We start the discussion with electroweak processes in few-nucleon systems studied with the correlated Gaussian method. Then we describe quasi-elastic scattering with nuclear spectral functions, and meson productions with a [Formula: see text]-hole model. Nuclear modifications of the parton distribution functions determined through a global analysis are also discussed. Finally, we discuss issues to be addressed for future developments.

Abstract
This study explored ethical treatment decisions of healthcare professional students beginning their education. As part of a first-semester modern medicine and bioethics course, 311 students watched and discussed, in interprofessional groups, a video titled Dax's Case: Who Should Decide? regarding the treatment of a life-threatening infectious disease against Dax's wish. The students then discussed and made their decision regarding treating or not. Their decisions, recorded on a worksheet, were classified as "will treat" or "won't treat." Professional groups' decision patterns were compared using the chi-square test. Overall, 151 (71%) opinions from students were classified as "will treat," and 61 (29%) as "won't treat." Nursing students were more likely to decide "won't treat" (in line with Dax's preference); however, the majority of other professions' students favoured treatment (against Dax's wish). Given the students' limited exposure to profession-specific education, our preliminary study supports the notion that healthcare profession students hold different values that align with their chosen profession at the start of their studies.

Potentially inappropriate medications in elderly Japanese patients: effects of pharmacists' assessment and intervention based on Screening Tool of Older Persons' Potentially Inappropriate Prescriptions criteria ver.2. J Clin Pharm Ther 2016; 42:209-214.

Abstract
WHAT IS KNOWN AND OBJECTIVES The Screening Tool of Older Persons' Potentially Inappropriate Prescriptions (stopp) criteria were updated in 2014 (stopp criteria ver.2), but few studies have evaluated the usefulness of stopp criteria in elderly patients. This prospective observational study evaluated the prevalence of potentially inappropriate medications (PIMs), and the efficacy of hospital pharmacists' assessment and intervention based on stopp criteria ver.2. METHODS The study was conducted at three medical units of Kobe University Hospital between April 2015 and March 2016. Pharmacists assessed and detected PIMs based on stopp criteria ver.2 and considered the patient's intention to change the prescription at the time of admission of each patient. If the pharmacists judged that benefits outweighed risks of prescription change and the patients consented to change the medications, they recommended the doctor to change the prescription. If there was a risk of exacerbation of disease by the change of medications and the pharmacists judged it to be difficult to adjust medications during hospitalization or the patients did not consent to change the medications, they did not recommend to change it. The pharmacists and the doctors discussed and finally decided whether to change the PIMs or not. The number of patients prescribed PIMs, the number and contents of PIMs, and the number of medications changed after pharmacists' intervention were calculated. RESULTS Totally, 822 new inpatients aged ≥65 years prescribed ≥1 daily medicine were included. Their median (interquartile range) age was 75·0 (71·0-80·0) years, and 54·9% were male. According to the criteria, 346 patients (42·1%) were prescribed ≥1 PIMs. Patients prescribed PIMs took significantly more medications than others: 10·0 (7·0-13·0) vs. 6·0 (4·0-9·0), P < 0·001. The total number of PIMs was 651%, 47·6% of which (n = 310) were recommended the doctors to change, and 292 of 651 PIMs (44·9%) were finally discontinued/changed after pharmacists' assessment and intervention. PIMs related to benzodiazepines, including Z-drugs, were most frequent, with a detailed classifications as follows (changed/total): (i) benzodiazepines for 4 or more weeks (75/205), (ii) drugs that predictably increase the risk of falls in older people (benzodiazepines) (30/67) and (iii) drugs that predictably increase the risk of falls in older people (hypnotic Z-drugs) (15/31). CONCLUSION Over 40% elderly patients were prescribed PIMs, and pharmacists' assessments and interventions based on stopp criteria ver.2 were useful in detecting and correcting prescription of PIMs.

Chromothripsis-like chromosomal rearrangements induced by ionizing radiation using proton microbeam irradiation system. Oncotarget 2016; 7:10182-92.

Abstract
Chromothripsis is the massive but highly localized chromosomal rearrangement in response to a one-step catastrophic event, rather than an accumulation of a series of subsequent and random alterations. Chromothripsis occurs commonly in various human cancers and is thought to be associated with increased malignancy and carcinogenesis. However, the causes and consequences of chromothripsis remain unclear. Therefore, to identify the mechanism underlying the generation of chromothripsis, we investigated whether chromothripsis could be artificially induced by ionizing radiation. We first elicited DNA double-strand breaks in an oral squamous cell carcinoma cell line HOC313-P and its highly metastatic subline HOC313-LM, using Single Particle Irradiation system to Cell (SPICE), a focused vertical microbeam system designed to irradiate a spot within the nuclei of adhesive cells, and then established irradiated monoclonal sublines from them, respectively. SNP array analysis detected a number of chromosomal copy number alterations (CNAs) in these sublines, and one HOC313-LM-derived monoclonal subline irradiated with 200 protons by the microbeam displayed multiple CNAs involved locally in chromosome 7. Multi-color FISH showed a complex translocation of chromosome 7 involving chromosomes 11 and 12. Furthermore, whole genome sequencing analysis revealed multiple de novo complex chromosomal rearrangements localized in chromosomes 2, 5, 7, and 20, resembling chromothripsis. These findings suggested that localized ionizing irradiation within the nucleus may induce chromothripsis-like complex chromosomal alterations via local DNA damage in the nucleus.

Intact attentional orienting towards inverted faces revealed by both manual responses and eye-movement measurement in individuals with Williams syndrome. JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2016; 60:969-981. [PMID: 27476718 DOI: 10.1111/jir.12318] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/31/2015] [Revised: 06/10/2016] [Accepted: 06/22/2016] [Indexed: 06/06/2023]
Abstract
BACKGROUND Individuals with Williams syndrome (WS) exhibit atypical attentional characteristics when viewing faces. Although atypical configural processing of faces has been reported in WS, the relative strengths of configural and local feature information to capture visual attention in WS remains unclear. We previously demonstrated that attentional capture by target-unrelated upright faces differs depending on what response is measured. Whereas eye movements reflected subtle atypical attentional properties at the late stage of visual search, manual responses could not capture the atypical attentional profiles towards target-unrelated upright faces in individuals with WS. Here we used the same experimental paradigm to assess whether sensitivity to configural facial information is necessary for capturing attention in WS. METHODS We measured both eye movements and manual responses from 17 individuals with WS and 34 typically developing children and adults while they were actively involved in a visual search task with an inverted face distractor. Task measures (reaction time and performance accuracy) and gaze behaviour (initial direction of attention and fixation duration) were analysed for each stimulus. RESULTS When the target and the inverted face were displayed in the same search array, reaction times and accuracies in individuals with WS showed similar tendencies as typical controls. Analysis of task and gaze measures revealed that attentional orienting towards inverted faces was not atypical. CONCLUSION Although individuals with WS exhibited atypical gaze behaviour towards upright faces in our previous study, this unusual behaviour disappears if the faces are upside down. These findings suggest that local feature information alone (e.g. eyes) does not contribute to the heightened attention to faces, but configural information appears necessary for drawing attention to faces in individuals with WS, at least in the current experimental paradigm.

Abstract
Objective: To evaluate the pressure under short-stretch and elastic bandages. Design: Prospective study in 20 healthy volunteers, comparing the two different kinds of bandages. Setting: Department of Surgery, Aichi Prefectural College of Nursing, Nagoya, Japan. Main outcome measures: Pressure measurements were made beneath the bandages with different initial pressures of 10, 20, 30, 40, 50, 60, and 70 mmHg, during supine resting, standing, tip-toe exercise and walking. Results: Short-stretch bandages showed a significant increase in pressure during standing and exercise at lower initial pressures compared with elastic bandages. In analysing the pressure waveform during tip-toe exercise and walking, a significantly greater pressure difference between muscle contraction and relaxation was noted for short-stretch bandages compared with elastic bandages at any initial pressures. Conclusions: Short-stretch bandages produce a higher working pressure and a larger pressure difference during exercise. However, the effect depends on the initial pressures at the time of application. In clinical practice, prevention of a decrease in pressure with time and uniform application of bandages are important.

Objective: To investigate the clinical significance of corona phlebectatica. Design: Clinical and plethysmographic evaluation of corona phlebectatica associated with primary varicose veins. Setting: Department of Surgery, Aichi Prefectural College of Nursing, Nagoya, Japan. Main outcome measures: In 411 limbs with greater saphenous incompetence, including 101 with skin changes and 310 without skin changes, clinical analysis and plethysmographic evaluation using the photoplethysmographic technique were carried out. Results: In 204 of 411 limbs, corona phlebectatica was observed, including 75 coloured red and 129 coloured blue. Blue coronas were observed significantly more often then red coronas in limbs with skin changes. The half refilling time in limbs with skin changes was significantly shorter than that in limbs without skin changes. In limbs without skin changes, limbs with blue coronas showed a significantly shortened half refilling time than those with red coronas. Conclusions: Blue coronas are a strong indicator of the presence of prolonged venous hypertension in varicose veins.

Abstract
Objective: To quantify the influence of posture and exercise on the interface pressure obtained under elastic stockings with compression pads. Design: Interface pressure measurement and plethysmographic evaluation of elastic stockings with and without compression pads. Setting: Department of Surgery, Aichi Prefectural College of Nursing, Nagoya, Japan. Main outcome measures: Pressure measurements in 24 volunteers were obtained beneath elastic stockings, elastic bandages and short-stretch bandages during supine resting, standing, tip-toe exercise and walking, and the effect of elastic stockings on the muscle pump of the leg was evaluated by strain-gauge plethysmography in 40 limbs with varicose veins. Results: Without compression pads, only short-stretch bandages showed a significant increase in pressure during standing and exercise. When pads were used, however, elastic stockings and bandages also showed a significant increase. With pads, significant improvement in the expelled volume during exercise was observed by strain-gauge plethysmography. Conclusions: Interface pressure under elastic materials during posture and exercise is similar to that under short-stretch bandages when compression pads are used, and pads effectively augment the muscle pump.

Abstract
Objective: This study was designed to determine the optimal physical methods for promoting venous return of the leg. Methods: Ten healthy volunteers were investigated in the supine position on a couch, and their peak femoral venous velocity and calf muscle volume were determined using duplex ultrasound and strain gauge plethysmography,respectively,before and during deep respiration, limb elevation, calf squeezing and various types of leg exercises. Results: Deep respiration showed the smallest effect on both percentage increase of peak flow velocity and expelled volume. Elevation of the leg showed the same effect on the expelled volume as calf muscle squeezing and ankle movement, while the former showed significantly less effect than the latter on the percentage increase of peak flow velocity. In both dorsal flexion of the ankle and squeezing at the calf, the stronger of each procedure caused more effective changes in haemodynamics. Ankle exercise was more effective in promoting venous return in the calf muscle than wiggling the toes, making circling movements with the feet or alternately flexing and spreading the toes. Conclusions: Ankle exercise or calf muscle squeezing, performed maximally,may be the first recommendation for reducing venous stasis at the calf muscle and prophylaxis of deep vein thrombosis..

Chromothripsis is the massive but highly localized chromosome rearrangements within a one-step catastrophic event rather than a series of subsequent and random alterations. Chromothripsis occurs commonly in various human cancers and it is thought to be associated with increasing malignancy and oncogenesis. However the causes and consequences of chromothripsis remain unclear. Therefore, to explore mechanisms of chromothripsis, we investigated whether chromothripsis was artificially induced by irradiation. We elicited DNA double-strand breaks in the oral cancer cell line HOC313, or its highly metastatic subline HOC313-LM by The Single Particle Irradiation system to Cell (SPICE), a focused vertical micro-beam system designed to irradiate the nuclei of adhesive cells. We established irradiated monoclonal sublines and analyzed the copy number variations (CNVs) and SNPs using SNP array. Chromosomal alterations, induced by irradiation including CNVs, were detected in some monoclonal sublines. Interestingly SNP array analysis showed that one subline named LM200-#25 had multiple chromosomal alterations which happened locally in chromosome 7. Moreover, we detected several chromosomal alterations such as t(12;7;11) translocation in LM200-#25 subline by Multi-Color FISH analysis. These results suggested that chromothripsis might be induced by irradiation in LM200-#25 subline.

Abstract
The dicentric chromosome assay (DCA) has been regarded as the gold standard of radiation biodosimetry. The assay, however, requires a 2-d peripheral blood lymphocyte culture before starting metaphase chromosome analyses to estimate biological doses. Other biological assays also have drawbacks with respect to the time needed to obtain dose estimates for rapid decision on the correct line of medical treatment. Therefore, alternative technologies that suit requirements for triage biodosimetry are needed. Radiation-induced DNA double strand breaks in G0 lymphocytes can be detected as interphase chromosome aberrations by the cell fusion-mediated premature chromosome condensation (PCC) method. The method, in combination with fluorescence in situ hybridization (FISH) techniques, has been proposed in early studies as a powerful tool for obtaining biological dose estimates without 2-d lymphocyte culture procedures. The present work assesses the applicability of FISH-based PCC techniques using pan-centromeric and telomeric peptide nucleic acid (PNA) probes in triage mode biodosimetry and demonstrates that an improved rapid procedure of the prematurely condensed dicentric chromosome (PCDC) assay has the potential for evaluating exposed radiation doses in as short as 6 h after the collection of peripheral blood specimens.

Abstract
The biological dose of nuclear workers engaged in emergency response tasks at Tokyo Electric Power Company (TEPCO) Fukushima Daiichi Nuclear Power Station was estimated in the present study. As the national core center for radiation emergency medical preparedness in Japan, the National Institute of Radiological Sciences (NIRS) received all individuals who were suspected of being overexposed to acute radiation. In the course of health examinations at NIRS, biological dosimetry was performed by the dicentric chromosome assay (DCA). Twelve individuals were examined from 21 March-1 July 2011. The results indicated that the estimated exposure doses for all individuals were lower than 300 mGy, with the mean value of about 101 mGy. These results by DCA were in accordance with those obtained by physical dosimetry based on personal dosimeter recording assessment. The results corroborate the fact that no acute radiation syndrome was observed among the workers examined.

Abstract
Single nucleotide polymorphisms (SNPs) in the interleukin 28B gene (IL28B) are good pretreatment predictors of anti-hepatitis C virus (HCV) therapy with interferon. SNPs of the inosine triphosphatase (ITPA) gene are associated with reduced haemoglobin levels during treatment with ribavirin. The i-densy™ (Arkray, Inc.), which is based on the quenching probe (QP) method, automatically detects target genes in blood samples by fluorescence quenching within 100 min. Using a QP and primer set, a gene amplification response is generated that can quickly and easily detect a specific gene's arrangement by fluorometry. The present study was conducted to compare the utility of i-densy (QP method) with that of conventional direct sequencing (DS) for detecting SNPs in the IL28B and ITPA genes in chronic hepatitis C patients. Between June 2011 and January 2012, 73 consecutive patients underwent genotyping of IL28B, and 54 patients underwent genotyping of ITPA. All of the patients were seropositive for HCV-RNA. The IL28B and ITPA genotypes were tested for bi-allelic polymorphisms in rs8099917 (T/T, T/G and G/G; minor allele, G) and rs1127354 (C/C, C/A and A/A; minor allele, A), respectively. The results obtained with the QP method were identical to those obtained with the conventional DS method. The frequency of the IL28B genotypes TT, GT and GG were 74%, 24.7% and 1.4%, respectively, and those of the ITPA genotypes CC, AC and AA were 68.5%, 29.6% and 1.9%, respectively. These results indicate that the i-densy using the QP method can automatically, quickly and easily identify genotypes of IL28B and ITPA.

Abstract
OBJECTIVES Exercise of the leg with external limb compression has been reported to be useful for preventing and reducing leg oedema. The aim of this study was to investigate the effects of leg gaiters on calf muscle pump activity. METHODS Continuous measurements of the interface pressure at the leg during exercise and determination of the femoral venous velocity at the groin during exercise were carried out in healthy volunteers with elastic stockings alone, leg gaiters alone and gaiters over the elastic stockings. RESULTS The greatest pressure difference between muscle contraction and relaxation during exercise was observed when gaiters were applied over the elastic stockings at the calf. Gaiters alone without elastic stockings led to a significantly greater pressure difference between muscle contraction and relaxation during exercise than elastic stockings alone (P < 0.01). A significantly higher value of the peak flow velocity of the femoral vein was observed with the combined use of gaiters and elastic stockings than the single use of elastic stockings. CONCLUSIONS Leg gaiters have a beneficial effect of augmenting venous femoral blood flow during calf muscle pump activity in volunteers with a normal valve function of leg veins.

Interface pressure is affected by slippage of bandages at thigh. INT ANGIOL 2012; 31:544-549. [PMID: 23222932] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 06/01/2023]
Abstract
AIM Very little is known about how compression bandages lose interface pressure. We hypothesized that the loss of interface pressure is correlated with the slippage of the bandages, and studied the interface pressure and slippage of three bandages over 8 hours. METHODS Twenty-Seven legs from 27 healthy volunteers were bandaged with short stretch bandages (SS), cohesive short stretch bandages (CS), and long stretch bandages (LS). Pressure sensors were placed above the ankle (B1), below the knee (D), and mid thigh (F). Interface pressures in a sitting position were recorded at the beginning, and 4 and 8 hours later. In 17 legs, the pressure sensor sites were marked, and their heights were measured on standing upright. RESULTS SS and CS lost interface pressure quickly, but LS maintained pressure better than SS and CS at all sites. There was no pressure difference between SS and CS at the lower leg. However, CS maintained pressure better than SS at the mid thigh (44.6% vs. 54.4% pressure loss at 8 hours, respectively. P=0.037). There was a tendency toward less slippage with CS than SS at the mid thigh. In CS and LS, there was a linear correlation between the slippage of bandages and the interface pressure at the mid thigh (P <.01, in both). CONCLUSION The interface pressure may be affected by the slippage of bandages at the thigh, but not at the lower leg. Cohesive short stretch bandages may exert their beneficial impact at the thigh.

Abstract
The Japanese Archipelago stretches over 4000 km from north to south, and is the homeland of the three human populations; the Ainu, the Mainland Japanese and the Ryukyuan. The archeological evidence of human residence on this Archipelago goes back to >30 000 years, and various migration routes and root populations have been proposed. Here, we determined close to one million single-nucleotide polymorphisms (SNPs) for the Ainu and the Ryukyuan, and compared these with existing data sets. This is the first report of these genome-wide SNP data. Major findings are: (1) Recent admixture with the Mainland Japanese was observed for more than one third of the Ainu individuals from principal component analysis and frappe analyses; (2) The Ainu population seems to have experienced admixture with another population, and a combination of two types of admixtures is the unique characteristics of this population; (3) The Ainu and the Ryukyuan are tightly clustered with 100% bootstrap probability followed by the Mainland Japanese in the phylogenetic trees of East Eurasian populations. These results clearly support the dual structure model on the Japanese Archipelago populations, though the origins of the Jomon and the Yayoi people still remain to be solved.

Microarray CGH analyses of chromosomal 20q deletions in patients with hematopoietic malignancies. Cancer Genet 2012; 205:18-24.

Abstract
The chromosomal abnormality del(20q) is mostly found in various myeloid disorders, including myelodysplastic syndromes, myeloproliferative neoplasms, and acute myeloid leukemia. Here, microarray comparative genomic hybridization (aCGH) analyses of 14 patients cytogenetically confirmed to carry the del(20q) aberration in their bone marrow demonstrated that all deletions were interstitial and both the proximal and distal breakpoints varied among individuals. The centromeric breakpoints were located in the 20q11.21-12 region, and the telomeric breakpoints, in the 20q13.13-13.33 region. The extent of the deletion ranged from 11.2 to 27.3 Mb, and the commonly deleted region (CDR) was estimated to be 7.2 Mb in size. Two commonly retained regions were present, the proximal region adjacent to the centromere (20q11.1-11.21) and a subtelomeric one (20q13.33). The CDR of our study was more distal than reported previously. Furthermore, in three patients fluorescence in situ hybridization (FISH) demonstrated that del(20q) cells were detected at a higher frequency in the karyotype analyses than by interphase FISH and aCGH analyses. As the size and breakpoints of del(20q) have been reported to vary among patients, the presence of one or more tumor suppressor genes in the CDR has been suggested. Our study will contribute to the identification of candidate tumor suppressor genes on 20q.

Abstract
Objectives To investigate the acceptability of newly developed separated elastic stockings, which are divided into two portions at the ankle. Methods The difficulty in putting on and taking off stockings was compared between the original or modified separated stockings with various techniques in order to reduce the shift of the stockings and current non-separated stockings in healthy volunteers and patients with lymphoedema by applying both stockings alternately. In the modified model, the shift during daily activities was measured in healthy volunteers and patients with lymphoedema. Results The two items, ‘easier compared with non-separated stockings’ and ‘much easier’, were chosen at rates of 75% and 81% for putting on and taking off stockings for the original separated stockings and 75% and 75% for the modified separated stockings, respectively. Complaints during daily activities with the modified type to the stockings decreased as compared with the original type. The shift of stockings after an average 11-hour application was 1.6 ± 3.0 SD mm (range: 0–10 mm). Conclusions Modified separated elastic stockings are easier to put on and take off compared with current non-separated stockings, and they can be used safely because of their low-level shift during daily activities.

Abstract
Objectives To compare the interface pressure and stiffness between various combinations of compression material. Methods Using a stiffness-determining device, the interface pressure and stiffness were determined in several combinations of five elastic stockings and two elastic bandages. Results In the double stockings system, the interface pressure increased significantly and the highest stiffness was observed in double short-stretch stockings. When short-stretch bandages were applied over either short- or long-stretch stockings, a significant increase in stiffness was observed at any initial pressure compared with the single use of short-stretch stockings. In double bandage systems, when short-stretch bandages were applied over either short- or long-stretch bandages, the stiffness increased significantly. When long-stretch bandages were used over short-stretch bandages, the stiffness decreased significantly. Conclusions The stiffness is changeable according to the combinations of material, such as double stockings, double bandages and the wearing of bandages over stockings. The use of short-stretch bandages as the outside layer produces the highest stiffness at a high initial pressure.

Abstract
Objective To evaluate the reliability of a newly developed stiffness-determining device, composed of a leg mannequin and air-pack type analyser, for measuring the interface pressure. Method The correlation of stiffness values obtained employing the Hohenstein method and this new method was investigated using 17 different brands of medical elastic compression stocking. Results A significant correlation in stiffness values using the two methods was obtained ( P < 0.01). When this new method was applied to the bandages, the stiffness was significantly correlated with the initial pressure when assessing both short-stretch and long-stretch bandages. On the comparison of stiffness values between elastic stockings and bandages with the same initial pressure, the short-stretch bandages showed a predominantly higher value than long-stretch bandages and stockings ( P < 0.01). Conclusion The reliability of this new method, which can be easily applied to not only elastic stockings but also elastic bandages, was verified. In clinical practice, the compression pressure should be selected in consideration of the prospective stiffness.

Abstract
BACKGROUND/AIMS This study investigated the accuracy and usefulness of a newly improved three-dimensional measurement system for measuring the volume and circumference at the foot as well as at the calf and ankle. METHODS Regarding the newly improved device, halogen light was projected from four directions instead of the conventional two directions. The circumference and volume were measured in the morning and evening with and without elastic stockings in 23 healthy subjects. RESULTS The average circumference at the foot calculated using the 'average method', in which the circumference of the foot was measured in 10 places every 1 mm and the values were averaged, significantly increased in the evening compared with in the morning. When stockings were applied, the significant differences in the circumference or volume between the morning and evening disappeared at all sites of the leg. CONCLUSION The newly improved three-dimensional measurement system incorporating the halogen light from four directions, in which the foot circumference was calculated using an 'average method', was reliable and useful for evaluating edema at the foot as well as at the calf and ankle. The beneficial effect of elastic stockings on edema prevention was observed at all sites of the leg.

Abstract
Mass mortality of cultured yellowtail, Seriola quinqueradiata, has recently been reported from fish farms in western Japan. Previous studies revealed that diseased fish were characterized by encephalomyelitis and presporogonic stages of a myxosporean-like parasite in the spinal cord. However, the parasite has remained unidentified because of the lack of mature stages being present. Thus, in the present study, analysis of the small subunit ribosomal DNA (18S rDNA) of the parasite as well as in situ hybridization (ISH) studies using histological sections of the infected tissue was conducted. The 18S rDNA of the myxosporean had higher sequence similarities with those of bile-duct-infecting myxosporeans rather than those infecting nervous tissues and was identified as Myxobolus spirosulcatus. The ISH using specific probes demonstrated that the DNA amplified was derived from the multinuclear organisms found in histological sections. A highly sensitive and specific PCR-based assay for M. spirosulcatus was developed, which revealed a high prevalence of infection in cultured yellowtail that exhibited the clinical signs of encephalomyelitis.

Abstract
OBJECTIVES To compare the interface pressure during rest and exercise among various kinds of arm sleeves. METHODS The interface pressure underneath nine different arm sleeves was measured during 10 maximal opening and closing movements of fingers using a pressure transducer (Air Pack Type Analyser) in 16 healthy volunteers. Furthermore, in order to evaluate the characteristics of each arm sleeve, the extensibility, stiffness and thickness were determined in vitro by several apparatuses. RESULTS There was a significant correlation between stiffness and extensibility. The stiffness was significantly correlated with the pressure difference between muscle contraction and relaxation during exercise. The higher the value of stiffness, the greater the pressure amplitude during exercise. CONCLUSION Short-stretch arm sleeves characterized with a high level stiffness, including thick round- and flat-knitted arm sleeves, are more beneficial for the augmentation of muscle pumping than long-stretch arm sleeves, in the same way as short-stretch bandages or stockings applied to the leg.
