Abstract
BACKGROUND Few studies have evaluated the effects of rabeprazole on low-dose aspirin (LDA)-induced gastroduodenal injuries. AIM To conduct a randomised, double-blind, triple-dummy, active-controlled, multicentre trial, named the PLANETARIUM study, to assess the efficacy, dose-response relationship and safety of rabeprazole for peptic ulcer recurrence in Japanese patients on long-term LDA therapy. METHODS Eligible patients had a history of endoscopically confirmed peptic ulcers and were receiving long-term LDA (81 or 100 mg/day) therapy for cardiovascular or cerebrovascular protection. Subjects were randomly segregated into three groups receiving rabeprazole 10 mg once daily (standard dose in Japan), rabeprazole 5 mg once daily, or teprenone (geranylgeranylacetone; mucosal protective agent commercially available in Japan) 50 mg three times per day as an active control. The primary endpoint was recurrence of peptic ulcers over 24 weeks. RESULTS Among 472 randomised subjects, 452 subjects (n = 151, 150, 151, respectively) constituted the full analysis set. The cumulative recurrence rates of peptic ulcers over 24 weeks in the 10- and 5-mg rabeprazole groups were 1.4% and 2.8%, respectively, both of which were significantly lower than that in the teprenone group (21.7%). The cumulative occurrence rate of bleeding ulcers over 24 weeks in the teprenone group was 4.6%, while bleeding ulcers were not observed in the 10- or 5-mg rabeprazole groups. Rabeprazole was well tolerated at both doses. CONCLUSION Rabeprazole prevents the recurrence of peptic ulcers with no evidence of a major dose-response effect in subjects on low-dose aspirin therapy.

Abstract
Although we have obtained comprehensive catalogs of genetic risk loci that are linked to human diseases, little is known regarding how to devise a systematic strategy to integrate genetic study results with diverse biological resources. Such strategies will be crucial for providing novel insights into disease biology and for aiding drug discovery as an ultimate goal. Here we describe the current progress in this field using a pioneering example of large-scale genetic association studies on rheumatoid arthritis (RA), an autoimmune disease characterized by inflammation and destruction of joints. Through functional and bioinformatic annotations of risk single nucleotide polymorphisms (SNPs) and genes from >100 RA risk loci identified by genome-wide association study (GWAS) meta-analysis, we found novel biological insights into RA pathogenicity. Further, by integrating RA genetic findings with the complete catalog of approved drugs for RA and other diseases, we provide empirical data to indicate that human genetic-based approaches may be useful for supporting 'genetics-driven genomic drug discovery' efforts in complex human traits and suggest that further development of integrative approaches should be undertaken.

Abstract
The preferences of the West Indian sweet potato weevil, Euscepes postfasciatus (Fairmaire), to tubers of sweet potato, Ipomoea batatas (L.), for food and for oviposition were evaluated, and correlated to sweet potato's resistance to immatures. Adults (parent) were released in a plastic box containing tubers of sweet potato cultivars and maintained for 5 d, after which the adults on each tuber were counted. All adults were then removed and each tuber was maintained separately. New adults that emerged from the tubers were counted. Cultivars were grouped by cluster analyses using the number of parent adults on the tubers and the number of new adults emerging from the tubers, adjusted for the weight of each tuber. Cultivars were divided into five groups: average level of preference, preferred, preferred for oviposition but not for food, preferred for food but not for oviposition, and not preferred. New adults from the first two groups took less time to eclose than those from the other groups, and their body size was smaller. In a second experiment, one to five cultivars were selected from each group and inoculated each tuber with 10 weevil eggs on each cultivar. Although the proportion of eclosed adults was not significantly different between cultivars, the time to eclosion was shorter and body size was smaller on preferred cultivars. The selection of tubers by parent adults was not linearly related with larval development, and did not reduce the survival of the immatures.

Abstract
We examined the role of Mag, an autoimmune susceptibility locus encoded by the telomeric region of MRL/MpJ mouse chromosome 1, in the pathogenesis of autoimmune exocrinopathy. At nine to 12 months of age, strain-specific differences were observed in the pancreas of the animals. B- and T-cell-containing periductal/perivascular cell infiltrations in the pancreases of MRL/MpJ and B6.MRLc1 congenic C57BL/6-background Mag-carrying strains were more severe than were those of C57BL/6. Pancreatic periductal/perivascular cell infiltration was observed frequently in A/J, AKR/N, B6.MRLc1, C57BL/6, and MRL/MpJ, moderately in DBA/1 and DBA/2, and rarely in BALB/c and C3H/He strains. Females tended to have greater pancreatic periductal/perivascular cell infiltration than males. C57BL/6 mice possessed defined borders between cell infiltrations and acini, but borders were indistinct in MRL/MpJ and B6.MRLc1 mice. We attributed this to the invasion of inflammatory cells between each acinus and the disruption of acinar cells around cell infiltrations in the latter strains. No strain-specific differences were observed in the appearance of fibrotic lesions and high endothelial venules in the cell infiltrates. The levels of serum anti-dsDNA antibodies and amylase, and mRNA expression of tumor necrosis factor-α and Fc gamma receptor III (encoded on Mag) in the pancreases, were elevated in MRL/MpJ- and B6.MRLc1-strain mice relative to C57BL/6. These results emphasized the crucial roles of Mag in the molecular and genetic pathogenesis of autoimmune-mediated pancreatitis.

Abstract
AIM Recently, TRPA1 channels, richly expressed in both peripheral and central neural systems, have been proposed as novel sensors of changes in oxygen concentration along the hypoxic-hyperoxic continuum. In this study, we investigated the hypothesis that TRPA1 channels blockade should profoundly affect the hypoxic ventilatory response (HVR). METHODS We examined the chemosensory ventilatory responses in conscious mice before and after intraperitoneal administration of the specific TRPA1 antagonist HC-030031 in two doses of 50 and 200 (cumulative dose 250) mg kg(-1) . Ventilation and its responses to mild 13% and severe 7% hypoxia, pure O2 , and 5% CO2 in O2 were recorded in a whole-body plethysmograph. RESULTS TRPA1 antagonism caused a dose-dependent attenuation of the HVR. Ventilatory stimulation was virtually abrogated in response to the mild, but it remained viable, albeit slashed, at severe hypoxia after the bigger dose of HC-030031. The TRPA1 function seemed specific for the hypoxic chemoreflex as neither the response to pure O2 nor hypercapnia was appreciably influenced by the TRPA1 antagonist. CONCLUSIONS The study unravelled the role of TRPA1 in shaping the ventilatory response to low-intensity hypoxia, liable to be mediated by vagally innervated respiratory chemosensors of lower functional rank, but contradicted the TRPA1 being indispensable for the powerful carotid body chemoreflex in face of a severe hypoxic threat.

Abstract
Numerous reports have shown that a diet containing large amounts of trans fatty acids (TFAs) is a major risk factor for metabolic disorders. Although recent studies have shown that TFAs promote intestinal inflammation, the underlying mechanisms are unknown. In this study, we examined the effects of dietary fat containing TFAs on dextran sodium sulphate (DSS)-induced colitis. C57 BL/6 mice were fed a diet containing 1·3% TFAs (mainly C16:1, C18:1, C18:2, C20:1, C20:2 and C22:1), and then colitis was induced with 1·5% DSS. Colonic damage was assessed, and the mRNA levels of proinflammatory cytokines and major regulators of T cell differentiation were measured. The TFA diet reduced survival and exacerbated histological damage in mice administered DSS compared with those fed a TFA-free diet. The TFA diet significantly elevated interleukin (IL)-6, IL-12p40, IL-23p19 and retinoic acid-related orphan receptor (ROR)γt mRNA levels in the colons of DSS-treated animals. Moreover, IL-17A mRNA levels were elevated significantly by the TFA diet, with or without DSS treatment. We also examined the expression of proinflammatory cytokines in lipopolysaccharide (LPS)-stimulated RAW264.7 cells and peritoneal macrophages. These cells were exposed to TFAs (linoelaidic acid or elaidic acid) with or without LPS and the mRNA levels of various cytokines were measured. IL-23p19 mRNA levels were increased significantly by TFAs in the absence of LPS. Cytokine expression was also higher in LPS-stimulated cells exposed to TFAs than in unexposed LPS-stimulated cells. Collectively, our results suggest that TFAs exacerbate colonic inflammation by promoting Th17 polarization and by up-regulating the expression of proinflammatory cytokines in the inflamed colonic mucosa.

Abstract
Abstract Progressive degradation of the extracellular matrix (ECM) of articular cartilage and bone by enhanced activities of proteinases is an essential step for joint destruction in rheumatoid arthritis (RA) and osteoarthritis (OA). Among the proteinases, matrix-degrading metalloproteinases play a key role in joint destruction. Recent studies have indicated that these metalloproteinases comprise members of the matrix metalloproteinase (MMP) and a disintegrin and metalloproteinase (ADAM) gene families. The MMP family is composed of 19 different members and classified into five subgroups of collagenases, gelatinases, stromelysins, membrane-type MMPs, and other MMPs. They have the ability to digest almost all ECM components in human tissues when they act in concert. Their prospective roles in RA and OA joint destruction have been well established. On the other hand, the ADAM family members are classified into ADAM metalloproteinases and catalytically inactive nonproteolytic homologues. The ADAM metalloproteinases contain ADAM with a transmembrane domain (membrane-type ADAM) and ADAM with thrombospondin motifs (ADAMTS). Although members in both groups are known to degrade ECM components, ADAMTS species may be especially important for the aggrecan (cartilage proteoglycan) degradation of articular cartilage in RA and OA, since aggrecanases-1 and -2 are included in this group. This review outlines the characters of the MMP and ADAM gene family members and their roles in joint destruction in RA and OA.

Abstract
We observed the motion of an organelle transported by motor proteins in cells using fluorescence microscopy. Particularly, among organelles, the mitochondria in PC12 cells were studied. A mitochondrion was dragged at a constant speed for several seconds without pausing. We investigated the fluctuation dissipation theorem for this constant drag motion by comparing it with the motion of Brownian beads that were incorporated into the cells by an electroporation method. We estimated the viscosity value inside cells from the diffusion coefficients of the beads. Then the viscosity value obtained by using the beads was found to be slightly lower than that obtained from the diffusion coefficient for the organelle motion via the Einstein relation. This discrepancy indicates the violation of the Einstein relation for the organelle motion.

Abstract
BACKGROUND AND PURPOSE The characteristics of reverse magnetic resonance angiography and diffusion-weighted imaging (MRA-DWI) mismatch (RMM), defined as a large DWI lesion in the absence of major artery occlusion (MAO), remain unknown, especially in patients treated with intravenous recombinant tissue plasminogen activator (rt-PA). METHODS Patients with stroke in the middle cerebral artery territory were included. Early ischaemic changes (EIC) were assessed with the Alberta Stroke Program Early CT Score on DWI (DWI-ASPECTS). All patients were divided into four groups based on the presence of MAO and a DWI-ASPECTS cut-off value of <7. RMM was defined as DWI-ASPECTS <7 without MAO. Clinical characteristics, symptomatic intracerebral hemorrhage (sICH) and favorable functional outcome (modified Rankin Scale score 0-2) at 90 days were compared amongst the four groups. RESULTS Of the 486 patients enrolled (167 women, median age 74 years, median initial National Institutes of Health Stroke Scale score 13), reverse MRA-DWI mismatch was observed in 24 (5%). Of the clinical characteristics, cardioembolism was the only factor that was independently associated with RMM [odds ratio (OR) 5.49, 95% confidence interval (CI) 1.25-24.1]. Multivariable analyses revealed that patients with RMM more commonly had sICH than those with DWI-ASPECTS ≥ 7 irrespective of the presence (OR 5.44, 95% CI 1.13-26.1) or absence (13.1, 2.07-83.3) of MAO, and they had a more favorable functional outcome than those with DWI-ASPECTS < 7 plus MAO (7.45, 2.39-23.2). CONCLUSION RMM was observed in 5% of patients treated with rt-PA and associated with cardioembolism. Patients with RMM may benefit from thrombolysis compared with those with EIC with MAO, although increment in the rate of sICH is a concern.

Abstract
The objective of this study was to investigate ethnic differences in the glyoxylate reductase/hydroxypyruvate reductase (GRHPR) gene in patients with primary hyperoxaluria type 2 (PH2). GRHPR was genotyped in Japanese patients with PH2 and all GRHPR mutations described to date were reviewed in terms of geographic and ethnic association. We identified a novel mutation, a two-nucleotide deletion (c.248_249delTG) in exon 3 creating a premature 'stop' at codon 91. Also, we found that the c.864_865delTG mutation was associated with the rs35891798 single-nucleotide polymorphism. The allelic frequencies of the c.103delG, c.494G>A, c.403_404+2 delAAGT, and c.864_865delTG mutations in PH2 patients were 37.8%, 15.6%, 10.0%, and 10.0%, respectively. All patients with the c.103delG mutation were Caucasian. Patients with the c.494G>A mutation and 78% (7/9) of those with the c.403_404+2 delAAGT mutation were from the Indian subcontinent, whereas those with the c.864_865delTG mutation were Chinese or Japanese. Molecular analysis of GRHPR of four Japanese PH2 patients identified a novel mutation (c.248_249delTG in exon 3). Caucasians with PH2 should be screened for the c.103delG mutation; patients from the Indian subcontinent for c.494G>A; and patients of East Asian origin (particularly) for c.864_865delTG. The prevalence of the latter mutation in PH2 patients from East Asia was 75.0%.
