Abstract
BACKGROUND In examining childhood overweight/obesity, there is a need to consider both eating quickly and eating until full. This longitudinal study investigated the influence of eating quickly and/or eating until full on anthropometric variables and becoming overweight/obese among Japanese schoolgirls. METHODS Study participants were fourth-grade schoolgirls (aged 9 or 10 years) in Ina Town, Japan. Physical examinations and a questionnaire survey were performed at baseline (fourth grade) and after 3 years (seventh grade). Height, weight, and waist circumference were measured in the physical examinations, while the data on eating quickly and eating until full were collected in the questionnaire survey. Analysis of variance and analysis of covariance were used to compare the differences in each anthropometric variable between fourth and seventh grade among groups. RESULTS Data on 425 non-overweight/obese schoolgirls in fourth grade were analyzed. Gains in anthropometric variables (body mass index, waist circumference, and waist-to-height ratio) from fourth to seventh grade were significantly larger in the "eating quickly and eating until full" group than in the "not eating quickly and not eating until full" group. In contrast, there were no significant differences in the gains between the "eating quickly or eating until full" group and the "not eating quickly and not eating until full" group. The proportion of overweight/obese girls in seventh grade was higher in the "eating quickly and eating until full" group than in the other groups. CONCLUSIONS Eating quickly and eating until full had a substantial impact on excess gains in anthropometric variables among schoolgirls, suggesting that modifying these eating behaviors may help prevent non-overweight/obese girls from the excess gains. Accordingly, school health programs need to focus on not eating quickly and/or not eating until full to prevent overweight/obesity; it is necessary to emphasize "the risk of overweight/obesity associated with these eating behaviors" in schools.

Abstract
BACKGROUND This study examined the relationship between rapid weight gain during infancy and/or early childhood and anthropometric measurements [body mass index (BMI), percent body fat (%BF), waist circumference (WC) and waist-to-height ratio (WHtR)] in preadolescence by sex. METHODS Subjects were fourth-grade school children (aged 9 to 10 years) from elementary schools in Ina-town, Japan, in 2010. Measurements of height, weight, %BF and WC were conducted for each subject. We obtained data on height and weight of subjects at birth, age 1.5 years and age 3 years from the Maternal and Child Health handbook. Rapid weight gain was defined as a change in weight-for-age standard deviation score greater than 0.67 from birth to age 1.5 years (infancy) or from age 1.5 to 3 years (early childhood). RESULTS All anthropometric variables (BMI, %BF, WC and WHtR) at age 9 to 10 years were significantly higher in the rapid weight gain during both infancy and early childhood period group than in the no rapid weight gain group, regardless of sex. When compared with the no rapid weight gain group, rapid weight gain during early childhood period had significantly higher BMI and WC in boys and BMI, %BF and WC in girls. Compared with the no rapid weight gain group, the rapid weight gain during infancy group had a significantly higher WC in boys and significantly higher BMI and WC in girls. CONCLUSION Rapid weight gain during both infancy and early childhood was related to higher anthropometric measurements, including WHtR, among Japanese preadolescents, regardless of sex. This study suggests that rapid weight gain during infancy and early childhood may be a risk factor for general/abdominal obesity later in life.

Abstract
We conjugated nucleoside derivatives that have anti-HIV-1 activities with oligopeptides that should bind to the gp120 of the HIV-1 virion, and examined their anti-HIV-1 activities. These derivates included 3′-azido-2′,3′-dideoxythymidine (AZT), 2′,3′-dideoxyuridine (ddU), 2′,3′-dideoxycytidine (ddC), 2′,3′-dideoxyinosine (ddI) and 2′,3′-dideoxyadenine (ddA). Dipeptides consisting of N-carbomethoxy-carbonyl-prolyl-phenylalanylbenzyl ester (CPF) and oligopeptides derived from the complementarity-determining region 2 (CDR2) of domain 1 of CD4 were synthesized. The N-terminals of these peptides were conjugated with the 5′OH of AZT, ddU, ddC, ddl or ddA through carbonyl moieties. CPF conjugated with AZT, ddC, ddl or ddA through two-carbonyl moieties exhibited powerful anti-HIV-1 activity, which was similar to that of the respective nucleosides when compared at the same molar concentration. No complex compound connected by a one-carbonyl moiety had anti-HIV-1 activity, whereas a tetrapeptide or octapeptide of the CDR2 region combined with AZT did have such activity. The toxicity of these CPF-containing compounds to human peripheral blood lymphocytes was slightly weaker than the toxicities of the corresponding nucleosides lacking CPF. Antiviral nucleosides containing oligopeptides may be used as lead compounds in an effort to isolate more effective and less cytotoxic anti-HIV-1 agents.

Abstract
BACKGROUND The objective of this study was to examine the relationship between rapid weight gain during early childhood and overweight in preadolescence by sex. METHOD Study subjects were 676 boys and 620 girls in fourth grade (aged 9 or 10 years) from elementary schools in Ina-town, Japan, during 2010-2012. Height and weight of subjects at birth, age 1.5 and 3 years, were collected from the Maternal and Child Health Handbook, while values at 9-10 years were measured. Rapid weight gain was defined as a change in weight-for-age standard deviation score greater than 0.67 from birth to age 1.5 years (0-1.5 years) or from age 1.5 to 3 years (1.5-3 years). RESULTS After adjustment for confounding factors, compared with no rapid weight gain, rapid weight gain during 0-1.5 years and 1.5-3 years or rapid weight gain during 1.5-3 years but not during 0-1.5 years significantly increased the odds ratio (OR) for overweight at age 9-10 years in boys (OR, 6.21; 95% confidence interval [CI], 2.84-13.58 and OR, 3.31; 95% CI, 1.67-6.54, respectively) and girls (OR, 7.55; 95% CI, 2.99-19.07 and OR, 3.42; 95% CI, 1.38-8.49, respectively). CONCLUSION The present study suggests that rapid weight gain during early childhood was associated with being overweight in preadolescence, regardless of sex.

Abstract
Seminoma, the most common testicular malignant neoplasm, originates from germ cells and is characterized by the presence of numerous tumour-infiltrating lymphocytes (TILs). Although it is widely accepted that TILs function in surveillance and cytotoxicity in various tumours including seminoma, detailed mechanisms governing TIL recruitment are not fully understood. It has been shown that high endothelial venule (HEV)-like vessels are induced in inflamed and neoplastic tissues and contribute to lymphocyte recruitment in a manner similar to the way physiological lymphocyte homing occurs in secondary lymphoid organs. Here, we report that HEV-like vessels, which express MECA-79(+) 6-sulfo sialyl Lewis X-capped structures, are induced in TIL aggregates in seminoma, and that such vessels potentially recruit circulating lymphocytes, as an E-selectin•IgM chimera bound these vessels in a calcium-dependent manner. These HEV-like vessels express intercellular adhesion molecule 1 (ICAM-1), but not vascular cell adhesion molecule 1 (VCAM-1) or mucosal addressin cell adhesion molecule 1 (MAdCAM-1), which likely contributes to lymphocyte firm attachment. We also found that the number of T cells attached to the luminal surface of HEV-like vessels was greater than the number of B cells (p < 0.0001). Interestingly, while CD8(+) cytotoxic T lymphocytes (CTLs) attached to the lumen of HEV-like vessels were scarcely detected, significant numbers of proliferative CTLs were observed outside vessels. These histological findings strongly suggest that TILs, particularly T cells, are recruited to seminoma tissues via HEV-like vessels, and that tumour-infiltrating CTLs then undergo proliferation after transmigration through HEV-like vessels in testicular seminoma.

Abstract
Intracerebral hemorrhage (ICH) is a major cause of morbidity and mortality in Japan. Seventeen Japanese institutions are participating in the Antihypertensive Treatment for Acute Cerebral Hemorrhage (ATACH) II Trial (ClinicalTrials.gov no. NCT01176565; UMIN 000006526). This phase III trial is designed to determine the therapeutic benefit of early intensive systolic blood pressure (BP) lowering for acute hypertension in ICH patients. This report explains the long run-up to reach the start of patient registration in ATACH II in Japan, including our preliminary study, a nationwide survey on antihypertensive treatment for acute ICH patients, a multicenter study for hyperacute BP lowering (the SAMURAI-ICH study), revision of the official Japanese label for intravenous nicardipine, and construction of the infrastructure for the trial.

Abstract
BACKGROUND/AIMS Rapid removal of plasma amyloid-β (Aβ) by blood purification may serve as a peripheral Aβ sink from the brain for Alzheimer's disease therapy. We investigated the reduction of plasma Aβ during hemodialysis and cognitive states. METHODS Aβ concentrations and Mini-Mental State Examinations (MMSE) were investigated in 37 hemodialysis patients (68.9 ± 4.1 years). RESULTS The dialyzers effectively removed Aβ(1-40) and Aβ(1-42), 63.9 ± 14.4 and 51.6 ± 17.0% at 4 h dialysis, resulting in the reduction of Aβs in whole-body circulation by 51.1 ± 8.9 and 32.7 ± 12.0%, respectively. Although the plasma Aβs before dialysis (750.8 ± 171.3 pg/ml for Aβ(1-40)) were higher than those reported for Alzheimer's disease patients, the cognitive states of hemodialysis patients were relatively normal, especially of longer dialysis vintages. CONCLUSIONS Dialyzers effectively reduced Aβs in whole-body circulation. Repeated rapid decrease of plasma Aβs might maintain cognitive state.

Abstract
SETTING Japan's National Tuberculosis Programme (NTP). OBJECTIVES To determine and assess the chronological change of chronic excretors. DESIGN We compared two groups of chronic excretors (continuous excretion of TB bacilli in the last 2 years) classified by time of registration; the first group was registered from 1991 to 1997, and the second from 1998 to 2004. The epidemiological situation and the NTP were also compared. RESULT There were 481 cases in the first group, comprising 0.17% of registered cases, and 159 cases in the second group, comprising 0.06%. Stratified analysis by treatment regimen and TB category confirmed a decrease in the ratio of chronic excretors in all sub-groups. Human factors such as non-adherence, no drug susceptibility testing (DST) on initiation of treatment and inadequate modification of treatment in new sputum smear-positive cases were more frequent in the first group than in the second (37.0% vs. 28.9%, 19.5% vs. 10.7%, 36.8% vs. 19.5%, P < 0.05). Other known risk factors, such as interruption due to side effects and complication of diabetes and/or alcoholism, were similarly distributed. CONCLUSION The decline in chronic excretors has been associated with the DOTS strategy, baseline DST and appropriate modification of treatment regimen in new sputum smear-positive cases.

Abstract
Ohtahara syndrome (OS) is one of the most severe and earliest forms of epilepsy. We have recently identified that the de novo mutations of STXBP1 are important causes for OS. Here we report a paternal somatic mosaicism of an STXBP1 mutation. The affected daughter had onset of spasms at 1 month of age, and interictal electroencephalogram showed suppression-burst pattern, leading to the diagnosis of OS. She had a heterozygous c.902+5G>A mutation of STXBP1, which affects donor splicing of exon 10, resulting in 138-bp insertion of intron 10 sequences in the transcript. The mutant transcript had a premature stop codon, and was degraded by nonsense-mediated mRNA decay in lymphoblastoid cells derived from the patient. High-resolution melting analysis of clinically unaffected parental DNAs suggested that the father was somatic mosaic for the mutation, which was also suggested by sequencing. Cloning of PCR products amplified with the paternal DNA samples extracted from blood, saliva, buccal cells, and nails suggested that 5.3%, 8.7%, 11.9%, and 16.9% of alleles harbored the mutation, respectively. This is a first report of somatic mosaicism of an STXBP1 mutation, which has implications in genetic counseling of OS.

Abstract
We report a Japanese girl affected with a neonatal-onset form of propionic acidaemia (PA). She developed severe metabolic crisis after dehydration at 2 years of age. Bradycardia with complete atrioventricular block responded to haemodiafiltration, but severe cardiac failure was refractory to inotropic treatment. She was diagnosed with acute cardiac dysfunction caused by PA-induced metabolic crisis. Extracorporeal membrane oxygenation (ECMO), a technique for providing mechanical circulatory support, was required. This is the first case report of a PA patient who recovered from a life-threatening metabolic crisis with cardiac failure by ECMO. Cardiac failure may be a cause of death, but it is occasionally an under-recognized complication. Mitochondrial dysfunction in the myocardium due to propionyl-CoA could contribute to the pathomechanism of cardiac complications of PA. We believe that ECMO should be attempted in PA patients with cardiac failure, in addition to haemodiafiltration and other therapeutic measures, because doing so may lead to the recovery of cardiac dysfunction, as was evident in our patient. In conclusion, prompt investigations and management of cardiac complications should be performed immediately during PA-induced metabolic crises.

Abstract
Abstract
Neutron diffraction measurements for liquid (l-) Te have been performed. The first minimum after the first peak of g(r) is well above zero and filled up with temperature, while the second peak diminishes substantially and flattens out at high temperature. The temperature variations of g(r) are analyzed combining the structural information available from our EXAFS results. The curve fitting of g(r) for l-Te predicts that two different inter-chain components coexist. The first corresponds to the short-distance inter-chain component around 3.2Å and the second corresponds to the long-distance inter-chain component around 3.8Å. The filling of the first minimum around 3.2Å at high temperature is clearly related to the metallization. EXAFS analysis on the basis of the model g(r) indicates that the short-distance inter-chain component (P2) responsible for the metallic conduction in l-Te as well as the nearest intra-chain component (P1) are required for fitting the oscillatory spectrum in the region of short-range sensitivity of the EXAFS signal. It is concluded that the S-M transition observed for l-Te arises from the transformation to the densely packed configuration composed of shortened chain molecules.

Abstract
To assess oxidative stress (OS) induced by endurance exercise, concentrations of serum reactive oxygen species (ROS) were determined in 70 Japanese male amateur runners completing a two-day ultra-marathon race. Serum ROS levels were analyzed at three time points: before the race (baseline), after the 1st day race (mid-race), and after the 2nd day race (goal) (post-race). The means (SE) of ROS were 151.4(3.7) (U. CARR.), 168.7(4.4), and 156.8(4.4), respectively. Significant positive trends were noted between age and serum ROS concentrations at the three race points (p<0.05 for all). After adjusting for age, BMI and average monthly running distance, the baseline serum ROS concentrations were positively associated with completion times of the first-day race, in particular (p<0.05), suggesting that the concentrations may predict physical performance. The ROS production increased at mid-race (p<0.05), but the levels returned to baseline levels at post-race, indicating that an antioxidant defense system may develop post-race to reduce OS.

Abstract
We investigated the possible influence of an exhaustive physical exercise on mental stress biomarkers (serotonin, tryptophan, and beta-endorphin) along with dopamine, noradrenaline and free fatty acids in an ultramarathon race in which 45 km was run on the first day and 90 km on the second. We obtained serum samples at 6 different time points during and after the race from 18 Japanese male runners who completed the marathon. Overall changes of serum serotonin and tryptophan concentrations were statistically significant according to ANOVA for repeated measurements (p < 0.05). Serum serotonin levels elevated rapidly on the first day with the post hoc Tukey's test. Tryptophan concentrations inversely decreased during the race, possibly because of utilization for synthesis of serotonin. Levels of beta-endorphin appeared to increase on the first and second days, but were not statistically significant. In conclusion, serum serotonin, tryptophan and beta-endorphin appeared to be used for mental stress markers in physical exercise.

Abstract
BACKGROUND As Bowen's disease of the nail apparatus is quite rare, there have been only a few reports on the prevalence of human papillomavirus (HPV) infection in this condition. OBJECTIVES The purpose of this study was to clarify the association of HPV with this disease involving the nail apparatus. METHODS Five patients with Bowen's disease of the nail apparatus were investigated clinically, virologically and histologically. Total DNAs extracted from excised skin lesions were analysed using polymerase chain reaction (PCR) for the presence of HPV DNA and the amplified products were subjected to DNA sequence analyses. Histological localization of HPV DNA was examined by in situ hybridization. RESULTS In three of five patients, HPV was detected by PCR amplification, and subsequent sequence analyses of the PCR products showed the sequences of HPV type 56. A common clinical feature of the three HPV-positive patients was longitudinal melanonychia. In contrast, the two HPV-negative patients presented with a convex nail deformity and a periungual ulcerative lesion. In two of three positive cases, there was a silent point mutation in the L1 gene of each HPV. In the remaining one case, the nucleotide sequence was consistent with the consensus sequence of HPV 56. Sequence analyses of the E6 gene revealed the infection of different variants of HPV 56 among the three cases. The viral genomes were located in keratinocyte nuclei upon in situ hybridization. CONCLUSIONS HPV 56 may be involved in the carcinogenesis of Bowen's disease affecting the nail matrix with longitudinal pigmentation.

Abstract
Using the urinary 8-hydroxydeoxyguanosine (8-OHdG) concentration, effects of participation in a two-day ultramarathon race period on oxidative DNA damage were investigated in Japanese nonprofessional runners. Before the first day (baseline), after the first day (mid-race) of 40-km running, and after the second day (post-race) of 90 km running, biomaterials were successfully sampled from 95 participants (males, 79; females, 16) who completed the full race. We analyzed urine for 8-OHdG and blood for aspartate aminotransferase (AST), creatine phosphokinase (CPK) and myoglobin, and evaluated fluctuation in the values at three sampling time points. Adjusted baseline urinary 8-OHdG levels (microg/g creatinine) (mean +/- standard deviation) showed no significant differences between males and females, at 2.85 +/- 1.17 and 3.04 +/- 1.56, respectively. In males, mid-race urinary 8-OHdG levels rose to 3.29 +/- 1.15 (p < 0.01), but then returned to 2.73 +/- 1.16 at the post-race time point (p < 0.01). In females, a similar increase to 3.32 +/- 1.47 and subsequent decline to 2.80 +/- 1.47 were noted. In contrast, AST, CPK and myoglobin were increased at both mid- and post-time points and particularly the latter, independent of the sex. Extreme prolonged exercise in a two-day ultramarathon race period causes oxidative DNA damage but antioxidant repair systems are apparently induced to protect against oxidative DNA stress with physical exercise.

Abstract
This paper describes an indoor behavioral monitoring system for improving the quality of life in ordinary houses. It employs a device that uses weak radio waves for transmitting the obtained data and it is designed such that it can be installed by a user without requiring any technical knowledge or extra constructions. This study focuses on determining the usage statistics of home electric appliances by using an electromagnetic field sensor as a detection device. The usage of the home appliances is determined by measuring the electromagnetic field that can be observed in an area near the appliance. It is assumed that these usage statistics could provide information regarding the indoor behavior of a subject. Since the sensor is not direction sensitive and does not require precise positioning and wiring, it can be easily installed in ordinary houses by the end users. For evaluating the practicability of the sensor unit, several simple tests have been performed. The results indicate that the proposed system could be useful for collecting the usage statistics of home appliances.

Abstract
The functions of filopodia and lamellipodia in mature osteoclasts are not well known in the process of bone resorption. We investigated the function of filopodial/lamellipodial movement in mature osteoclasts by video-enhanced contrast-differential interference contrast (VEC-DIC) microscopy. Mature osteoclasts, which were isolated from Japanese white rabbits, were cultured on calcium phosphate (CP)-coated quartz coverslips to observe filopodial/lamellipodial movement and the formation of CP-free areas precisely. Filopodia broke the CP substrate into pieces and transported them to the cell body by capturing them at the tip. Lamellipodia destroyed the CP substrate, and transported it to the cell body by capturing small particles in a mass. This study suggests two functions of filopodia and lamellipodia in mature osteoclasts, i.e., the mechanical fragmentation of the CP substrate and the transportation of the CP particles to the cell body.

Abstract
Primary erythermalgia is a rare neuropathy characterized by attacks of burning pain and redness in the extremities in response to warm stimuli. We describe here a boy with erythermalgia whose painful attacks began in infancy. We found a novel mutation of SCN9A, which is a responsible gene for primary erythermalgia in this case. In his teens, he developed wintry hypothermia with resultant neurological dysfunction and recurrent pneumonia. During the course of pneumonia, he had transient encephalopaty with a reversible lesion in the splenium of the corpus callosum. In addition to excessive cooling, a defect in central thermoregulation may have caused hypothermia in this patient.

Abstract
BACKGROUND AND AIMS Gastric acid secretion is downregulated by Helicobacter pylori infection and upregulated after its eradication, but the mechanisms are still unclear. We examined the effects of H pylori eradication on the number of parietal cells and on expression of molecules functioning in acid secretion in the human gastric mucosa. METHODS We enrolled 111 consecutive men with chronic gastritis induced by H pylori. Biopsy specimens were endoscopically obtained before and 12 weeks after successful eradication of H pylori and parietal cell numbers were counted. mRNA expression levels of H+/K+-adenosine triphosphatase (H+/K+-ATPase), anion exchanger 2, M3 muscarinic receptor, intrinsic factor, and interleukin 1beta were determined with a real time reverse transcriptase-polymerase chain reaction method. The severity of gastric atrophy was evaluated using the serum pepsinogen I/II ratio. RESULTS No significant difference was observed in parietal cell numbers before and after H pylori eradication. Median mRNA expression levels of H+/K+-ATPase in the gastric mucosa increased 250-fold after H pylori eradication accompanied by attenuation of interleukin 1beta. A large increase in H+/K+-ATPase expression was observed even in patients with severe atrophic gastritis. In contrast, fold increases in mRNA expression levels, including intrinsic factor, anion exchanger 2, and M3 muscarinic receptor, after eradication therapy, were limited to 1.4, 2.3, and 2.5 times, respectively. CONCLUSIONS In the absence of alteration of parietal cell number, gastric H+/K+-ATPase mRNA expression was markedly restored after successful H pylori eradication, suggesting a central role for the restoration of H+/K+-ATPase expression in gastric acid secretion recovery after H pylori eradication.

Abstract
The aim of this study was to compare the diagnostic yield of flexible video bronchoscopy (FVB) and autofluorescence bronchoscopy (i.e. lung imaging fluorescence endoscopy (LIFE)) in 151 patients at a high risk of lung cancer and with moderate dysplasia or worse on sputum cytology mass screening. Findings from FVB and LIFE were classified as either normal, abnormal or suspicious for cancer. Endobronchial biopsies (EBX) were obtained from abnormal or suspicious areas on FVB and/or LIFE, or randomly when FVB and LIFE were normal. Moderate dysplasia and worse were defined as pathologically positive. Overall, 83 out of 343 (24%) EBX were pathologically positive. The sensitivity of FVB was 72% and LIFE 96%. Relative sensitivity of LIFE over FVB was 1.33. Specificities of FVB and LIFE were 53 and 23%, respectively. The numbers of pathologically positive EBX from sites designated normal, abnormal or suspicious were: from FVB, 23 out of 162 (14%), 37 out of 151 (25%) and 23 out of 30 (77%); from LIFE, three out of 69 (4%), 44 out of 212 (21%) and 36 out of 62 (58%). In normal or abnormal areas at FVB, there was a significant increase in the yield of EBX guided by abnormal and suspicious sites noted at LIFE. In conclusion, endobronchial biopsies of suspicious findings from lung imaging fluorescence endoscopy and flexible video bronchoscopy have a good diagnostic yield. Lung imaging fluorescence endoscopy is more useful when flexible video bronchoscopy is either normal or abnormal.

Abstract
It has been implicated that glia activation plays a critical role in the progression of Alzheimer's disease (AD). However, the precise mechanism of glia activation is not clearly understood yet. In our present studies, we confirmed our previous results where change the levels of neuropeptides and peptidases in ibotenic acid (IBO) infusion into the rat nucleus basalis magnocellularis, an animal model of AD. Furthermore, we extended our study to investigate a possible protection effect of co-administration on the changes of neuropeptides, and neuronal and glial cells in IBO-infused rat brain by memantine treatment. The levels of substance P and somatostatin were decreased in the striatum and frontal cortex 1 week after IBO infusion, and recovered to the control level by memantine treatment, indicating the involvement of neuropeptides in AD pathology. Furthermore, the immunohistochemical and enzymatic studies of GFAP and CD 11b, and peptidylarginine deiminase, markers of glia, in the striatum and frontal cortex showed the increase in IBO-treated rat brain as compared with controls, while co-administration of memantine and IBO no increase of astrocytes and microglia activation was observed. The present biochemical and immunohistochemical results suggest that glia activation might play an important role to the pathology of AD, and correlate with the changes of neuropeptide levels in AD brain that is recovered by memantine treatment.

Abstract
BACKGROUND We investigated the use of high magnification bronchovideoscopy combined with narrow band imaging (NBI) for the detailed examination of angiogenic squamous dysplasia (ASD). This was carried out in relation to bronchial vascular patterns with abnormal mucosal fluorescence in heavy smokers at high risk for lung cancer. METHODS Forty eight patients with sputum cytology specimens suspicious or positive for malignancy were entered into the study. Conventional white light and fluorescence bronchoscopic examination was first performed. Observations by high magnification bronchovideoscopy with conventional white light were made primarily at sites of abnormal fluorescence, and then repeated with NBI light to examine microvascular networks in the bronchial mucosa. Spectral features on the RGB (Red/Green/Blue) sequential videoscope system were changed from the conventional RGB broadband filter to the new NBI filter. The wavelength ranges of the new NBI filter were B1: 400-430 nm, B2: 420-470 nm, and G: 560-590 nm. ASD tissues were also examined using a confocal laser scanning microscope equipped with argon-krypton (488 nm) and argon (514 nm) laser sources. RESULTS The microvessels, vascular networks of various grades, and dotted vessels in ASD tissues were clearly observed in NBI-B1 images. Diameters of the dotted vessels visible on NBI-B1 images agreed with the diameters of ASD capillary blood vessels diagnosed by pathological examination. Capillary blood vessels were also clearly visualised by green fluorescence by confocal laser scanning microscopy. There was a significant association between the frequency of dotted vessels by NBI-B1 imaging and tissues confirmed as ASD pathologically (p=0.002). CONCLUSIONS High magnification bronchovideoscopy combined with NBI was useful in the detection of capillary blood vessels in ASD lesions at sites of abnormal fluorescence. This may enable the discrimination between ASD and another pre-invasive bronchial lesion.

Abstract
The mode of cytokinesis, especially in determining the site of cell division, is not well understood in higher-plant cells. The division site appears to be predicted by the preprophase band of microtubules that develop with the phragmosome, an intracellular structure of the cytoplasm suspending the nucleus and the mitotic apparatus in the center. As the preprophase band disappears during mitosis, it is thought to leave some form of "memory" on the plasma membrane to guide the growth of the new cell plate at cytokinesis. However, the intrinsic nature of this "memory" remains to be clarified. In addition to microtubules, microfilaments also dynamically change forms during cell cycle transition from the late G2 to the early G1 phase. We have studied the relationships between microtubules and microfilaments in tobacco BY-2 cells and transgenic BY-2 cells expressing a fusion protein of green-fluorescent protein and tubulin. At the late G2 phase, microfilaments colocalize with the preprophase band of microtubules. However, an actin-depleted zone which appears at late prometaphase is observed around the chromosomes, especially at metaphase, but also throughout anaphase. To study the functions of the actin-depleted zone, we disrupted the microfilament structures with bistheonellide A, a novel macrolide that depolymerizes microfilaments very rapidly even at low concentrations. The division planes became disorganized when the drug was added to synchronized BY-2 cells before the appearance of the actin-depleted zone. In contrast, the division planes appeared smooth, as in control cells, when the drug was added after the appearance of the actin-depleted zone. These results suggest that the actin-depleted zone may participate in the demarcation of the division site at the final stage of cell division in higher plants.

Abstract
A phase II study of cisplatin, ifosfamide, and irinotecan with recombinant human granulocyte colony stimulating factor (rhG-CSF) support was conducted in previously untreated patients with stage IIIB or IV non-small-cell lung cancer (NSCLC). Between June 1998 and August 2001, 50 patients were registered in this phase II study. Cisplatin (20 mg m(-2)) and ifosfamide (1.5 g m(-2)) were administered on days 1-4 and irinotecan (60 mg m(-2)) was given on days 1, 8, and 15, respectively. This regimen was repeated every 4 weeks. rhG-CSF was administered subcutaneously at a dose of 50 microg m(-2) on days 5-18 except on the days of irinotecan treatment. In total, 49 patients were assessable for toxicity and response and 50 for survival. In all, 33, patients (67.3%; 95% confidence interval 57.4-77.2%) achieved an objective response. The median response duration was 192 days and the median time to progression for 49 patients was 170 days. The median survival time was 540 days with 1- and 2-year survival rates of 63.5 and 30.7%, respectively. Grade 3 or 4 neutropenia and thrombocytopenia developed in 63.3 and 38.8% of the patients, respectively. In conclusion, the combination of cisplatin, ifosfamide, and irinotecan with rhG-CSF support was highly effective for the treatment of stage IIIB or IV NSCLC with acceptable toxicities.

Abstract
Difficulty in gene transduction of human blood cells, including hematopoietic stem cells, has hampered the development of gene therapy applications for hematological disorders, encouraging the development and use of new gene delivery systems. In this study, we used a third-generation self-inactivating (SIN) lentiviral vector system based on human immunodeficiency virus type 1 (HIV-1) to improve transduction efficiency and prevent vector-related toxicity. The transduction efficiency of the HIV-1-based vector was compared directly with the Moloney murine leukemia virus (MLV) SIN vector in human leukemia cell lines. Initial transduction efficiencies were almost 100% for the HIV and less than 50% for the MLV vectors. Similar results were observed in 11 types of primary cells obtained from leukemia or myeloma patients. Transgene expression persisted for 8 weeks in cells transduced with the HIV vector, but declined with the MLV vector. In addition, resting peripheral blood lymphocytes and CD34(+) hematopoietic cells were transduced successfully with the HIV vector, but not with the MLV vector. Finally, we confirmed vector gene integration in almost all colony-forming cells transduced with the HIV vector, but not with the MLV vector. In conclusion, this lentiviral vector is an excellent gene transduction system for human blood cells because of its high gene transduction and host chromosome integration efficiency.

Abstract
BACKGROUND We have developed a method of high magnification bronchovideoscopy that enables improved observation of subepithelial vascular patterns of the bronchial mucosa. A study was undertaken to investigate the value of high magnification bronchovideoscopy in the detailed examination of dysplasia in the bronchial mucosa of patients with abnormal mucosal fluorescence. METHODS Thirty one patients with sputum cytology specimens suspicious or positive for malignancy were entered into the study. Conventional white light examination was first performed under local anaesthesia and fluorescence bronchoscopy was also carried out using a light induced fluorescence endoscopy (LIFE) lung system. A high magnification bronchovideoscope (XBF 200HM2) was then used to examine the microvascular network in the bronchial mucosa at sites of normal and abnormal fluorescence and the images obtained were compared with pathological diagnoses from bronchial biopsy specimens. Vascular area ratios were calculated using image analysing apparatus. RESULTS Vascular networks with regular patterns were observed at 20 of 22 abnormal fluorescence sites in biopsy specimens from patients with bronchitis. However, vascular networks with increased vessel growth and complex networks of tortuous vessels of various sizes were observed in 15 of 21 abnormal fluorescence sites in dysplasia specimens. There was a significant difference between bronchitis and dysplasia specimens (OR=25, 95% CI 5.5 to 113, p<0.0001). Mean vascular area ratios from 16 normal bronchial epithelium specimens with normal fluorescence, and 22 bronchitis and 21 dysplasia specimens with abnormal fluorescence were 0.054 (95% CI 0.039 to 0.07), 0.095 (95% CI 0.072 to 0.118), and 0.173 (95% CI 0.143 to 0.203), respectively. The results indicate a statistically significant increase in vascular area in the three groups (p<0.0001). CONCLUSION Areas of increased vessel growth and complex networks of tortuous vessels in the bronchial mucosa detected using a high magnification bronchovideoscope at sites of abnormal fluorescence may enable discrimination between bronchitis and dysplasia.

Abstract
BACKGROUND Urinary C-terminal telopeptide of type I collagen (u-CTx) has been reported to be a sensitive biochemical marker of bone turnover. There have been two assays for urinary CTx, which are alpha-CTx and beta-CTx. A newly developed immunoassay for serum CTx (s-CTx) is now available for assessment of bone resorption. We evaluated the effects of aging, menopause, and osteoporosis on the measurements of serum CTx and compared them to urinary CTx assays. METHODS In 79 premenopausal healthy women, 80 postmenopausal healthy women, 61 osteoporotic patients with vertebral fractures and 34 osteoporotic patients with hip fractures, s-CTx and urinary beta-CTx (u-betaCTx) were measured by ELISAs, and urinary alpha-CTx (u-alphaCTx) was measured by an RIA. RESULTS In all subjects, s-CTx significantly correlated with both u-alphaCTx (r=0.54) and u-betaCTx (r=0.51). There was no significant difference among s-CTx, u-alphaCTx and u-betaCTx in the T-scores of the postmenopausal group over the premenopausal group. These findings indicate that the value of s-CTx, as well as urinary CTxs, reflected the increase of bone resorption associated with menopause with a high degree of sensitivity. Patients with vertebral fractures had moderately increased concentrations of bone resorption markers compared to age-matched healthy postmenopausal women (T-score; s-CTx: 0.8, u-alphaCTx: 0.9, u-betaCTx: 0.7), whereas bone resorption markers in hip fracture patients were greatly increased compared to healthy postmenopausal women (T-score; s-CTx: 1.1, u-alphaCTx: 1.3 u-betaCTx: 1.3). The T-scores of u-CTxs against the postmenopausal group in vertebral fracture group and in hip fracture group were not significantly different from those of s-CTx. CONCLUSIONS s-CTx, as well as urinary CTxs, reflects the increase of bone resorption in patients with vertebral fractures and hip fractures.

Abstract
A facile method has been developed for the highly sensitive and selective determination of ultratrace Be(II) ion using a new fluorimetric reagent, 10-hydroxybenzo[h]quinoline-7-sulfonate (HBQS), under extremely alkaline conditions, at pH 12.0. This reagent is quite suitable for the very small ion, Be(II), to form a 6-membered chelate ring, compatible with a high fluorescence yield. The stoichiometry of the chelate is 1:1 for Be-HBQS at pH 12.0. The calibration graph gave a wide linear dynamic range, 2-100 nmol dm(-3) of Be(II) ion with the detection limit (3s blank) of 0.52 nmol dm(-3), or 4.7 pg cm(-3). The excellent sensitivity and toughness toward the matrix influence were demonstrated using the artificial sample solutions for air-dust. Coupled with the simple masking procedure using EDTA, the method enables one to determine Be(II) ion at nanomolar levels in the presence of metals at the natural abundance levels in air-dust samples, typically Al, Ca, Cu, Fe, Mg, Pb, and Zn at 130, 150, 1.0, 70, 33, 3.0, and 8.0 micromol dm(-3), respectively, in the final solution. The proposed method was successfully applied to the determination of Be in urban air.

Abstract
BACKGROUND The induction of epithelial cytokines/chemokines is crucial in the migration of leukocytes, and its regulatory mechanisms remain incompletely defined. OBJECTIVE To determine the role of IL-17, a CD4(+) T cell-derived cytokine, in modulation of primary bronchial epithelial cells, the expression of IL-6, IL-8, and intercellular adhesion molecule 1 (ICAM-1) and the potential involvement of mitogen-activated protein (MAP) kinases in IL-17-mediated signaling were examined. METHODS The levels of gene expression and protein production for IL-6 and IL-8 in IL-17-treated cells, in the presence or absence of MAP kinase inhibitors, were analyzed by RT-PCR and ELISA, respectively, and activation of MAP kinases was determined by Western blot analyses. RESULTS We showed first that IL-17 induced time-dependent expression of IL-6 and IL-8 but not of the chemokines eotaxin and RANTES. In addition, IL-17 induced activation of extracellular signal-regulated kinase 1/2 but not of p38 or JNK kinases. A selective MAP kinase kinase inhibitor, PD98059, inhibited IL-17-induced IL-6 and IL-8. A combination of IL-17 and each of the cytokines IL-4, IL-13, and IFN-gamma further enhanced IL-8 expression. IL-17 alone did not induce ICAM-1 expression and showed no effect on IL-4- or IL-13-induced ICAM-1 expression. In contrast, a combination of IL-17 and IFN-gamma augmented IL-6 and ICAM-1 expression. CONCLUSION These findings suggest that IL-17, alone or in combination with other cytokines, modulates airway inflammation via-in part-the expression of epithelial IL-6, IL-8, and ICAM-1.

Abstract
We present a case of severe hyperemesis gravidarum (HG) associated with thyrotoxicosis in a woman with a past history of an eating disorder. She had developed persistent HG from early pregnancy until about at the end of the second trimester with a body loss of 14 kg. Total parenteral nutrition was effective in alleviateing HG. It is suggested that even a past history of an eating disorder could be at risk of developing HG.
