Abstract
Super-Kamiokande atmospheric neutrino data were fit with an unbinned maximum likelihood method to search for the appearance of tau leptons resulting from the interactions of oscillation-generated tau neutrinos in the detector. Relative to the expectation of unity, the tau normalization is found to be 1.42 ± 0.35(stat)(-0.12)(+0.14)(syst) excluding the no-tau-appearance hypothesis, for which the normalization would be zero, at the 3.8σ level. We estimate that 180.1 ± 44.3(stat)(-15.2)(+17.8) (syst) tau leptons were produced in the 22.5 kton fiducial volume of the detector by tau neutrinos during the 2806 day running period. In future analyses, this large sample of selected tau events will allow the study of charged current tau neutrino interaction physics with oscillation produced tau neutrinos.

Abstract
BACKGROUND Although the anatomy of the Sylvian fissure is understood, there is little information on where to start its dissection in the pterional transsylvian (PT-TS) approach. At small craniotomy using the PT-TS approach, we set the entry point to the Sylvian fissure at 15 mm behind the anterior edge of the craniotomy along the Sylvian fissure and designated this site "point 15." Here we compared the utility of "point 15" with the Sylvian point (point on the Sylvian fissure giving rise to the horizontal and anterior ascending rami) that had been recommended earlier as the entry site for opening the Sylvian fissure. MATERIALS AND METHODS This study includes 16 patients with 7 ruptured and 9 unruptured anterior circulation aneurysms. We evaluated the usefulness of "point 15" in the PT-TS approach for aneurysmal neck clipping with respect to the adequacy of anatomical exposure and low invasiveness. RESULTS In 12 patients "point 15" provided for excellent anatomical exposure of the Sylvian fissure; complete neck clipping was possible with minimal brain retraction and damage. In two patients with ruptured aneurysms and thick subarachnoid hemorrhage and in two patients with unruptured aneurysms, the dissection had to be enlarged 3 to 4 mm distally without reaching the Sylvian point. In the latter two patients the Sylvian veins were tethered to frontal and temporal lobes. CONCLUSIONS The "point 15" was an easily set entry point to the Sylvian fissure. It provided for sufficient anatomical exposure at surgery for anterior circulation aneurysms; additional posterior dissection was required in rare cases. We found that "point 15" was useful in small craniotomies using the PT-TS approach.

Abstract
To better understand the cellular pathogenetic mechanisms of fetal alcohol spectrum disorder (FASD) and the therapeutic benefit of stem cell treatment, we exposed pregnant rats to ethanol followed by intravenous administration of neural stem cells (NSCs) complexed with atelocollagen to the new born rats and studied recovery of GABAergic interneuron numbers and synaptic protein density in the anterior cingulate cortex, hippocampus and amygdala. Prenatal ethanol exposure reduced both parvalbumin-positive phenotype of GABAergic interneurons and postsynaptic density protein 95 levels in these areas. Intravenous NSC treatment reversed these reductions. Furthermore, treatment with NSCs reversed impaired memory/cognitive function and social interaction behavior. These experiments underscore an important role for synaptic remodeling and GABAergic interneuron genesis in the pathophysiology and treatment of FASD and highlight the therapeutic potential for intravenous NSC administration in FASD utilizing atelocollagen.

Abstract
Restriction fragment length polymorphism analysis was carried out to tag the alien genes for brown planthopper (BPH) resistance and earliness introgressed from wild species Oryza australiensis into cultivated rice, O. sativa L. One introgression line (IR65482-4-136-2-2), resistant to biotypes 1, 2, and 3 of BPH and early in flowering, was selected from BC2F4 of the cross between O. sativa (IR31917-45-3-2) and O. australiensis (accession 100882). Recurrent parent, O. australiensis, and introgression line were surveyed for RFLP using probes of chromosomes 10 and 12. Two probes, RG457 and CDO98, detected introgression from O. australiensis. Cosegregation between introgressed characters and molecular markers was studied in F2 derived from the cross between the introgression line and recurrent parent. The gene for BPH resistance is linked with RG457 of chromosome 12 at a distance of 3.68 +/- 1.29 cM, and the gene for earliness is linked with CDO98 of chromosome 10 at a distance of 9.96 +/- 3.28 cM. Such close linkage is useful in marker-based selection while transferring BPH resistance from introgression line into other elite breeding lines. Introgression at the molecular level indicates that the mechanism of alien gene transfer is probably genetic recombination through crossing over rather than substitution of whole or large segment of chromosomes of wild species.

Abstract
BACKGROUND The renoprotective effects of angiotensin II type 1 receptor blockers (ARBs) have been demonstrated in a number of clinical studies, but there are few evaluations of long-term ARB treatment. We measured blood pressure, urine protein, and estimated glomerular filtration rate (eGFR) among patients under long-term (up to 9 years) treatment with candesartan cilexetil to evaluate its safety and effectiveness to protect renal graft function. METHODS This study of 41 patients (31 male and 10 female) who presented with proteinuria and hypertension (blood pressure >140/90 mm Hg) after receiving a renal graft. Their serum creatinine level at baseline was 1.51 ± 0.53 mg/dL. Cyclosporine or tacrolimus were concomitantly prescribed for 18 (43.9%) and 22 (53.7%) subjects, respectively. The ARB treatment period was ≥12 months (up to 9 years, mean 4.8 years). Combination with other antihypertensive drugs (calcium antagonists) was necessary in 14/41 subjects (34.1%). RESULTS Significant declines in blood pressure were observed during the treatment period; blood pressure reduction target (blood pressure <130/80 mm Hg) was met in 56.1% for systolic and 68.3% for diastolic pressure. No significant increase in serum creatinine level or eGFR was observed. Urinary protein was reduced to negative or marginal in 63.4% of the subjects, demonstrating a significant decrease. CONCLUSIONS Candesartan cilexetil was considered to be safe even for long-term treatment in renal transplant patients, and effective to protect renal graft function.

Abstract
OBJECTIVE Neonatal congenital tricuspid valve (TV) dysplasia and/or displacement (Ebstein's malformation) with severe tricuspid regurgitation (TR) is a challenging condition in which outcomes are frequently poor. Little is known about left ventricular (LV) function during the perinatal period in patients with congenital TV disease. The objective of this study was to evaluate LV function in fetuses with congenital TV anomalies associated with significant TR. METHODS Serial fetal echocardiograms in 16 fetuses with congenital TV dysplasia and/or displacement (five neonatal survivors and 11 fetal or neonatal deaths) were reviewed. LV stroke volume, LV end-diastolic volume (LVEDV), LV end-diastolic dimension (LVIDd), the LV eccentricity index, thoracic and cardiac areas and the cardiothoracic area ratio (CTAR), the right atrium area index, and LV longitudinal strains were compared according to gestational age and clinical outcome. RESULTS The gestational age-adjusted LVEDV (Z-score) was lower in late gestation (-1.2 ± 1.2 at last examination ≥ 28 weeks) than earlier in gestation (0.3 ± 1.5 at last examination < 28 weeks) and LV output was lower than reported late-gestation normal values. LV short-axis dimension correlated with LV volume and CTAR. LV mid-septal strain was lower than the normal average of fetal mid-septal strain and correlated with the LV eccentricity index. Among these parameters, only the LV eccentricity index differed between survivors and non-survivors. CONCLUSION LV function and anatomy are abnormal in fetuses with severe congenital TV anomalies and may be important contributors to outcome.

Abstract
Heat shock protein 90 (Hsp90) is a promising target for anti-tumor therapy. We previously reported the anti-tumor activity of a novel Hsp90 inhibitor, KW-2478, in multiple myeloma (MM) as a single agent. In this study, we examined the combinational effect of KW-2478 and bortezomib, a proteasome inhibitor, in vitro and in vivo. In vitro, KW-2478 enhanced bortezomib-induced cell growth inhibition, both in MM cell lines and primary patient MM cells. The combination of KW-2478 and bortezomib also induced caspase activation in MM cell lines. Interestingly, the combination synergistically enhanced the expression of Hsp70B, a homolog of Hsp70, in human MM cells and peripheral blood mononuclear cells, indicating Hsp70B could be a surrogate biomarker for the combination of Hsp90 and proteasome inhibitors. In vivo, the combination of KW-2478 with bortezomib showed synergistic anti-tumor activity without significant body weight loss in a subcutaneously inoculated human myeloma model. Furthermore, the combination also showed synergistic reduction of tumor burden in bone marrow in an orthotopic myeloma model. Our results strongly suggest that combination of KW-2478 with bortezomib could exhibit enhanced anti-tumor activity against human myeloma.

Abstract
PURPOSE OF INVESTIGATION It has been reported that interleukin (IL)-8 is produced in the amnion and that its production is enhanced by the initiation of labor. The purpose of this study was to clarify the mechanism of IL-8 production by amnion-derived (WISH) cells. METHODS Cells were cultured and treated with various concentrations of interleukin (IL)-1alpha, IL-1 receptor antagonist (ra), tumor necrosis factor (TNF)- alpha, C2-, C6-ceramide, mitogen-activated protein (MAP) kinase kinase (MEK) inhibitor (U0126) and pyridinyl imidazole (p38 MAP kinase inhibitor, SB203580). IL-8 in the culture medium was measured by ELISA. RESULTS The production of IL-8 was significantly increased by IL-1alpha or TNF-alpha, and the increase of IL-8 stimulated by IL-1alpha was suppressed by IL-1 ra in a dose-dependent manner. The increase in IL-8 production by IL-1alpha or TNF-alpha was further enhanced by simultaneous addition of C2-ceramide. The increase of IL-8 stimulated by IL-1alpha or TNF-alpha was also suppressed by treatment with U0126 or SB203580. The results of this study demonstrate that the production of IL-8 induced by IL-1alpha and TNF-alpha is enhanced by C2-ceramide, and suppressed by MEK inhibitor or P38 MAP kinase inhibitor. CONCLUSION The results suggest that ceramide-mediated accumulation and MAP kinase-mediated suppression of inflammatory events in the amnion may play an important role in the maintenance of pregnancy and initiation of labor.

Abstract
We present a search for differences in the oscillations of antineutrinos and neutrinos in the Super-Kamiokande-I, -II, and -III atmospheric neutrino sample. Under a two-flavor disappearance model with separate mixing parameters between neutrinos and antineutrinos, we find no evidence for a difference in oscillation parameters. Best-fit antineutrino mixing is found to be at (Δm2,sin2 2θ)=(2.0×10(-3) eV2, 1.0) and is consistent with the overall Super-K measurement.

Abstract
Accumulating evidence indicates that cyclooxygenase (COX)-2-derived prostaglandin (PG) E(2) is involved in the development of various tumors, including colorectal cancer. However, the precise contribution of microsomal PGE synthase (mPGES)-1, a terminal enzyme that acts downstream of COX-2 in the PGE(2)-biosynthetic pathway, to multiple processes of tumor development is not yet fully understood. Here, we show the pro-tumorigenic role of mPGES-1 in chemical carcinogen-induced colon carcinogenesis and intrasplenic tumor transplantation models. Genetic deletion of mPGES-1 significantly reduced both the total number and size of colorectal polyps at 18 weeks after azoxymethane administration with reduced nuclear translocation of β-catenin, altered expression profiles of chemokines/cytokines and increased production of antitumorigenic PGs, prostaglandin D(2) and prostacyclin in tumor tissues. At an early stage (6 weeks), mPGES-1 deficiency significantly reduced the number of aberrant crypt foci, while its transgenic overexpression increased the number. Furthermore, the growth of intrasplenically transplanted tumor cells was suppressed in mPGES-1 knockout (KO) mice. Co-culture of tumor cells with bone marrow-derived macrophages (BM-MΦs) isolated from wild-type (WT) mice resulted in the induction of mPGES-1 in BM-MΦs and increased the growth of tumor cells in vitro, whereas mPGES-1-null BM-MΦs failed to facilitate tumor growth. The adoptive transfer of WT BM-MΦs into mPGES-1 KO mice restored the growth of transplanted tumor cells, indicating that mPGES-1 in MΦs is important for the growth of adjacent tumor cells. Taken together, our findings suggest that the inhibition of mPGES-1 is an alternative therapeutic target for colorectal and possibly other cancers.

Abstract
The T2K experiment observes indications of ν(μ) → ν(e) appearance in data accumulated with 1.43×10(20) protons on target. Six events pass all selection criteria at the far detector. In a three-flavor neutrino oscillation scenario with |Δm(23)(2)| = 2.4×10(-3) eV(2), sin(2)2θ(23) = 1 and sin(2)2θ(13) = 0, the expected number of such events is 1.5±0.3(syst). Under this hypothesis, the probability to observe six or more candidate events is 7×10(-3), equivalent to 2.5σ significance. At 90% C.L., the data are consistent with 0.03(0.04) < sin(2)2θ(13) < 0.28(0.34) for δ(CP) = 0 and a normal (inverted) hierarchy.
