Abstract
The widespread detection of perfluorinated compounds (PFCs) in the water environment has been a concern for the last several years, while effluents from wastewater treatment facilities are the major sources of these compounds. Even advanced oxidation technologies (AOTs) are not useful for mineralization of the compounds due to their very high stability. Photochemical techniques using particularly vacuum UV (VUV) have been found to be very promising in this regard. But the use of VUV in UV-based AOTs has still not progressed much. Moreover, the impact of water quality on PFCs photomineralization is unknown. This investigation aimed to assess photomineralization potentials of perfluorooctanoic acid (PFOA) in ultrapure water (UPW), tap water (TW), surface water and treated wastewater effluent using a reactor setup enabling maximum utilization of VUV emission of low pressure lamp in laboratory batch experiments. Neya River water (NRW) and the Nakahama Wastewater Treatment Plant Effluent (NWWTPE) represented surface water and treated wastewater effluent respectively. Also, tests were carried out in 50% diluted NRW and NWWTPE. PFOA photomineralization in terms of PFOA removal, defluorination and total organic carbon (TOC) removal are discussed. The usefulness of the method for PFOA mineralization in organic-rich wastewaters, and further research needs are also highlighted.

Abstract
OBJECTIVES Patients with left unilateral spatial neglect draw a human face more satisfactorily than other objects. The aim of the present study is to examine the features of face drawings by patients with neglect and to establish their meaning in the diagnosis of neglect. METHODS Sixty-four right-handed patients with a right hemisphere stroke underwent the conventional test of the Behavioural Inattention Test (BIT) and showed left unilateral spatial neglect in one or more of the subtests. From the "drawing a man or woman" subtest, 64 samples of face drawing, in which both eyes were placed, were obtained. The percentage deviation of the location of the eyes in the face outline was calculated for 46 face drawings without discontinuity of the outline or severe distortion of the construction. The percentage deviation of the location of the eyes was compared among the patients with neglect, right-hemisphere damaged patients without neglect, and healthy control subjects. RESULTS The patients with neglect placed the eyes with greater leftward deviation in the face outline compared with the other two groups. The percentage deviation of the eyes was, however, not associated with neglect severity scored with the BIT conventional test. Forty-three percent of the patients with neglect located the eyes leftward beyond the normal range obtained from the performance of the healthy subjects, while none of the patients without neglect showed such abnormal leftward deviation. CONCLUSIONS The leftward deviation of the eyes in the face drawing suggests the presence but not the severity of left unilateral spatial neglect.

Abstract
Although the hippocampus is a brain region involved in short-term memory, the molecular mechanisms underlying memory formation are not completely understood. Here we show that sphingosine 1-phosphate (S1P) plays a pivotal role in the formation of memory. Addition of S1P to rat hippocampal slices increased the rate of AMPA receptor-mediated miniature excitatory postsynaptic currents (mEPSCs) recorded from the CA3 region of the hippocampus. In addition long-term potentiation (LTP) observed in the CA3 region was potently inhibited by a sphingosine kinase (SphK) inhibitor and this inhibition was fully reversed by S1P. LTP was impaired in hippocampal slices specifically in the CA3 region obtained from SphK1-knockout mice, which correlates well with the poor performance of these animals in the Morris water maze test. These results strongly suggest that SphK/S1P receptor signaling plays an important role in excitatory synaptic transmission in the CA3 region of hippocampus and has profound effects on hippocampal function such as spatial learning.

Abstract
AIM Leptin is one of the factors affecting serum lipid profile. We investigated the association between serum lipids and leptin/leptin receptor (LEPR) gene polymorphisms in obese Japanese children. METHODS One hundred and thirty-six obese children (99 males and 37 females, relative weight over than 20%) from 5 to 17 years of age were recruited from 10 institutes. Four known polymorphisms in leptin gene [(+19)A G, (-2548)G A, (-188)C A, (-633)C T] and four known polymorphisms in LEPR gene [Lys109Arg, Gln223Arg, Pro(G)1019Pro(A), Ser(T)343Ser(C)] were determined using polymerase chain reaction-restriction fragment length polymorphism-based analyses. RESULTS No associations were found between leptin gene polymorphisms and serum lipid profile. On the other hand, Lys109Arg and Ser343Ser polymorphism in LEPR gene, but not Gln223Arg or Pro1019Pro, had significant relationships with serum lipid profile; lower total and low-density lipoprotein cholesterol levels in Arg109Arg homozygotes, and lower TG levels in Ser343Ser(C/C) homozygotes. In addition, LEPR gene also associated with relative weight; Arg109Arg homozygotes had higher relative weight and Ser343Ser(C/C) homozygotes had lower one. CONCLUSION These results suggest that LEPR gene polymorphisms may partly contribute to serum lipid profile in obese children.

Abstract
BACKGROUND Ras association domain family 1A (RASSF1A) is a tumor suppressor that regulates the cell cycle, apoptosis, and microtubule stability. The association between the methylation levels of RASSF1A and the prognosis of clear-cell renal cell carcinoma (CCRCC) remains unclear. Therefore, we investigated this relationship to determine the prognostic value of RASSF1A methylation levels for CCRCC. PATIENTS AND METHODS The study comprised 179 Japanese patients who underwent radical or partial nephrectomy for CCRCC. The methylation level of 5' CpG islands in the RASSF1A was evaluated using combined bisulfite restriction analysis and bisulfite sequencing. RESULTS High levels of methylation in the RASSF1A promoter were significantly more frequent in grade 3 compared with grade 1 or 2 tumors (P = 0.028) and in patients with stage III or IV compared with patients with stage I or II (P = 0.043). Patients with high methylation levels had a significantly less favorable prognosis compared with those with low methylation levels (P = 0.040). Higher methylation levels were independently associated with a poor prognosis following multivariate analysis (P = 0.0053). CONCLUSION These results indicate that quantitative promoter methylation levels of the RASSF1A gene may be a useful marker to predict the prognosis of CCRCC.

Abstract
In Japan and Korea, outbreaks of scuticociliatosis have frequently occurred in Japanese flounder, Paralichthys olivaceus. Morphological observations and small subunit rRNA gene sequences have shown that the causative agent of scuticociliatosis in the flounder is Miamiensis avidus (syn. Philasterides dicentrarchi). In this study, we elucidated the antigenic differences between six Japanese M. avidus isolates as an initial step toward developing an effective vaccine against the disease. Four Japanese flounder isolates (IyoI, Nakajima, JF05To and Mie0301 isolates), one spotted knifejaw, Oplegnathus punctatus, isolate (SK05Kyo), and one ridged-eye flounder, Pleuronichthys cornutus, isolate (RF05To) were subjected to serological analysis. Antisera against IyoI, SK05Kyo, Nakajima and Mie0301 isolates were raised in rabbits and used for immobilization assays and Western blotting. Immobilization assays showed that the six isolates could be divided into three groups, tentatively designated serotype I for IyoI, JF05To, RF05To, SK05Kyo, serotype II for Nakajima and serotype III for Mie0301. Western blotting results supported these three serotypes, with marked similarities in the banding profiles of IyoI, JF05To, RF05To and SK05Kyo isolates, which were distinct from the Nakajima and Mie0301 isolates. Three isolates, IyoI, Nakajima and Mie0301 that were selected as representatives of each serotype, were highly pathogenic to Japanese flounder by experimental infection. Based on these findings, we propose that there are at least three M. avidus serotypes in Japan.

Abstract
OBJECTIVE To investigate the effects of umbilical cord milking on cardiopulmonary adaptation in very low birth weight infants. PATIENTS AND METHODS This study was the secondary analysis of a randomised control study of the effect of umbilical cord milking in premature infants. Forty singleton infants born between 24 and 28 weeks' gestation were randomly assigned to groups in which the umbilical cord was clamped either immediately after birth (control group, n = 20) or after umbilical cord milking (milked group, n = 20). Blood pressure, heart rate, urine output, fluid intake, and ventilatory index values in both groups were measured during the first 120 h after birth. RESULTS There were no significant differences in gestational age or birth weight between the two groups. The initial haemoglobin value was higher in the milked group (mean (SD) 16.5 (1.4) g/dl in the milked vs 14.1 (1.6) g/dl in the control; p<0.01). During the first 12 h, blood pressure was significantly higher in the milked group. Urine output in the milked group was higher than that in the control group during the first 72 h. There were no significant differences in heart rate, water intake, or ventilatory index values between the groups. CONCLUSION Umbilical cord milking may facilitate early stabilisation of both blood pressure and urine output in very low birth weight infants.

Abstract
A variety of evidence suggests brain-derived neurotrophic factor (BDNF) as a candidate gene for schizophrenia, and several genetic studies have shown a significant association between the disease and certain SNPs within BDNF (specifically, Val66Met and C270T). According to a recent study, the functional microsatellite marker BDNF-LCPR (BDNF-linked complex polymorphic region), which affects the expression level of BDNF, is associated with bipolar disorder. The goals of our current study were to 1) evaluate the quality of HapMap-based linkage disequilibrium (LD) tagging of BDNF-LCPR, 2) examine whether these tagging SNPs are associated with schizophrenia in a Japanese population, and 3) conduct a meta-analysis of the two most extensively studied polymorphisms: Val66Met and C270T. We genotyped eight tagging SNPs, including Val66Met and C270T. Our LD evaluation showed that BDNF-LCPR could be represented by these tagging SNPs in controls (with 73.5% allelic coverage). However, the functional A1 allele was not captured due to its low minor allele frequency (2.2%). In a case-control study (1117 schizophrenics and 1102 controls), no association was found in single-marker or multimarker analysis. Moreover, in a meta-analysis, the Val66Met polymorphism was not associated with schizophrenia, whereas C270T showed a trend for association in a fixed model (p=0.036), but not in a random model (p=0.053). From these findings, we conclude that if BDNF is indeed associated with schizophrenia, the A1 allele in BDNF-LCPR would be the most promising candidate. Further LD evaluation, as well as an association study in which BDNF-LCPR is genotyped directly, would be required for a more conclusive result.

Abstract
Lumbar disc degeneration is frequently seen in athletes. Lumbar disc diseases include a spectrum of diseases and/or symptoms, including lumbar disc degeneration. Some reports suggest an association between lumbar disc diseases and a functional single-nucleotide polymorphism (SNP;1184T/C, rs 2073711) of the cartilage intermediate layer protein ( CILP) gene. We hypothesized that lumbar disc degeneration occurrence may be significantly associated with SNP variants at the CILP gene in Japanese collegiate judo athletes. Eighty-nine Japanese judo athletes participated in this study. T2-weighted magnetic resonance imaging was used to define lumbar disc degeneration. Genotyping of the CILP gene (1184T/C) was performed using DNA sequencing. By using logistic regression analysis, significant associations of lumbar disc degeneration with the CILP C allele (odds ratio=4.1, 95% confidence interval: 1.57-10.71) and body weight (odds ratio=1.06, 95% confidence interval: 1.02-1.09) were observed. We conclude that the CILP gene 1184T/C polymorphism is a significant risk factor for lumbar disc degeneration occurrence in Japanese collegiate judo athletes.

Abstract
DNA analyses of the cystic fibrosis transmembrane conductance regulator (CFTR) gene in Japanese patients with idiopathic chronic pancreatitis (ICP) were performed to determine the relationship between the CFTR mutation and ICP. The study included patients with alcoholic pancreatitis (n = 20), patients with ICP (n = 20) and healthy volunteers (controls; n = 110). The poly-T region in intron 8 of the CFTR gene was analysed by direct sequencing. The CFTR coding region was screened using single-strand conformational polymorphism and direct sequencing. In the controls, frequencies of the 5T genotype and 5T allele were 4.5% and 3.6%, respectively. The frequency of the 5T genotype was significantly higher in the ICP group (20%) versus controls, but was not significantly different in alcoholic chronic pancreatitis patients (5%). Thus, the CFTR gene mutation, especially the 5T genotype, appears to have some relationship to ICP prevalence in Japanese patients independent of cystic fibrosis.
