Abstract
Abstract The purpose of this study was to demonstrate the radiological features of long bones in synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) syndrome and to correlate these with the clinical findings. Eleven long bone lesions in seven cases of SAPHO syndrome were examined. The patients ranged in age from 6 to 63 years, with a mean of 47 years. In all seven cases, radiography, (99m)technetium bone scintigraphy, CT scan, and magnetic resonance imaging (MRI) were performed. In six of the cases, bone biopsy and bone culture were carried out for 7 long bones. Seven of the involved lesions were from the shaft of the femur, one each was from the neck and the shaft of the humerus, and one was from the proximal tibia. These lesions showed radiologically hyperostosis, osteolysis, and bone infarction-like lesion. Osteolysis was occasionally accompanied by sclerotic change. Hyperostosis usually showed diaphyseal involvement, presenting low signal intensity on T1- and T2-weighted MR images. Histologically, these findings corresponded to massive bone necrosis, new bone formation, fibrosis, or a mixture of these associated with mild inflammatory cell infiltration. Osteolysis involved dyaphysis, metaphysis, or epiphysis associated with arthritis, and presented low signal intensity on T1-weighted images, nonhomogeneous signal intensity lower than fat on T2-weighted images, and high signal intensity on fat suppression images. These findings corresponded to fibrosis, granulation, and inflammatory cell infiltration with lymphocyte aggregation. Bone infarction-like lesion was observed in the shaft or neck of the femur and the humerus and accompanied by calcification and cystic change. Bone cultures were negative in all cases in which bone biopsy was performed. Although hyperostosis is thought to be a characteristic bone lesion in SAPHO syndrome, the long bone lesion can occasionally show not only hyperostosis but also osteolytsis and bone infarction-like lesions.

Abstract
To compare the responses of individual neutrophils to chemoattractants, migration pathway data were obtained using TAXIScan, an optically accessible/horizontal apparatus in which a concentration gradient is established reproducibly for a given stimulus. The observed linear-mode trajectory pattern of neutrophils toward N-formyl-methionyl-leucyl-phenylalanine (fMLP) or Interleukin (IL)-8/CXCL8 was distinguished from random migration patterns toward leukotriene (LT) B4 or platelet activating factor (PAF). The median values of velocity and directionality calculated for individual cells toward fMLP and IL-8 were both relatively similar and high, whereas the values toward LTB4 and PAF were widely dispersed over a lower range of directionality and from low to high ranges of velocity. The different patterns between the groups may be explained by unique morphology with single polarity toward fMLP and IL-8, and unstable morphology with multiple polarities toward LTB4 and PAF. Unique morphologies toward fMLP and IL-8 were not affected by coexisting LTB4 or PAF. On the other hand, the addition of suboptimum concentrations of fMLP or IL-8 to LTB4 or PAF induced a nearly maximum chemotactic response in most cells. These data suggest that exogenous formyl peptides and endogenous chemokines augment neutrophil accumulation at inflammation sites, whereas lipid mediators may play a role in supporting activation of the inflammatory cells for recruitment.

Abstract
Ensuring an appropriate dosage of renally eliminated drugs for patients with renal insufficiency is important for preventing adverse drug reactions. We investigated the effectiveness of interventions by pharmacists in a hospital pharmaceutical department. The comparative study was performed at Gifu Municipal Hospital in Japan from March to August 2011, and included an intervention (142 patients) and a control group (98 patients). Upon receiving a prescription of levofloxacin for patients aged > or = 75 years, pharmacists evaluated the patients' kidney function and adjusted the appropriate dosage at the time of dispensation. In the intervention and control groups, levofloxacin-induced adverse reactions developed in 6 of 142 (4.2%) and 13 of 98 (13.3%) patients, respectively (p < 0.05). The cost of reducing levofloxacin per patient was yen 191.1 and yen 0 in the intervention and control groups, respectively. The cost per patient for adverse reaction treatments and examinations was yen 15.5 and yen 290.0 in the intervention and control groups, respectively. The intergroup difference in the total cost per patient was yen 465.6. Dose adjustment of levofloxacin at the time of dispensation by the pharmacist for patients aged > or = 75 years resulted in a decrease in the incidence of adverse reactions and cost. These findings can be applied not only to hospitals, but also to community pharmacies, because the intervention, which is a manual system, is simply performed when pharmacists are dispensing drugs.

Abstract
Dipeptidyl peptidase-4 (DPP-4) inhibitors and other incretin-related drugs have attracted attention as antidiabetic agents, but they are expensive. The Japanese government has adopted a policy of reducing healthcare costs, and medical institutions must provide medical care while considering economic efficiency. This study was a comparative survey of the usage, treatment effectiveness, and cost of DPP-4 inhibitors. The subjects were patients prescribed DPP-4 inhibitors (sitagliptin, vildagliptin, and alogliptin) at Gifu Municipal Hospital between February 2010 and August 2011. HbA1c: Japan Diabetes Society values (%) and concomitant antidiabetic agents were surveyed for 12 weeks after the start of DPP-4 inhibitors. A cost-effectiveness analysis showed that the cost required for a 0.1% decrease in HbA1c for 12 weeks was the lowest with vildagliptin (2,478 yen; decrease in HbA1c: 0.75% +/- 0.85%). In a cost analysis with a virtual cohort of 1000 patients, the number of patients who achieved the treatment target (HbA1c 6.5%) was estimated with respect to a virtual cohort created based on the HbA1c level (7.59 +/- 1.13%) at baseline of 307 patients, in cases assuming the use of each DPP-4 inhibitor. In addition, the incremental cost-effectiveness ratio (ICER) was obtained with sitagliptin 50 mg as the reference. The number of patients achieving the treatment target was the highest with vildagliptin 100 mg (413 of 1000 patients), and the estimated ICER of 28,359 yen was the lowest. Robustness was also confirmed with a sensitivity analysis. These results suggest that vildagliptin provides a superior cost-benefit.

Abstract
Ureaplasma urealyticum could be a pathogen of non-gonococcal urethritis (NGU) in men. However, ureaplasma is often detected in men without NGU, and the proportion of cases possibly attributable to this pathogen is still undefined. We attempted to determine the bacterial loads of U. urealyticum significantly associated with NGU. The 16S rRNA genes of U. urealyticum were quantified by a real-time polymerase chain reaction-based assay in first-void urine (FVU) from 26 asymptomatic and 25 symptomatic men positive for U. urealyticum. The leucocyte counts in first-void urine (FVU) were determined as an objective measure of inflammatory response to ureaplasma in the hosts by automated quantitative urine particle analysis. Positive correlations were observed between copies of the 16S rRNA genes of U. urealyticum per ml and the leucocyte counts per µl in FVU (r = 0.49, p = 0.0003). Loads of ≥10(4) copies of the 16S rRNA gene of U. urealyticum/ml, corresponding to ≥5 × 10(3) cells of U. urealyticum/ml in FVU, were significantly associated with the presence of urethritis symptoms (p < 0.0001) and with higher leukocyte counts in FVU (p < 0.0001). The bacterial load of U. urealyticum, possibly of ≥5 × 10(3) cells of U. urealyticum/ml in FVU, could be significantly associated with the development of symptomatic NGU.

Abstract
Measures for prevention of Clostridium difficile-associated diarrhea, a common nosocomial infection, in hospital settings are urgently needed. This study was conducted to identify the risk factors contributing to C. difficile-associated diarrhea and to evaluate the clinical benefit of probiotics in its prevention. The study included 2716 patients at least 20 years old who received an injected antibiotic at any time between February 2010 and February 2011; a total of 2687 patients (98.9%) were assigned to the non-C. difficile-associated diarrhea group, and 29 patients (1.1%) were assigned to the C. difficile-associated diarrhea group. Univariate analysis revealed a significant difference between the two groups for the following factors: antibiotic therapy for > or = 8 days; enteral nutrition; intravenous hyperalimentation; fasting; proton pump inhibitor use; H2 blocker use; and serum albumin < or = 2.9g/dL (p<0.05). Multivariate logistic regression analysis revealed a significant difference between the two groups for several factors. Antibiotic therapy for > or = 8 days, intravenous hyperalimentation, proton pump inhibitor use, and H2 blocker use were therefore shown to be risk factors for C. difficile-associated diarrhea. Prophylactic probiotic therapy was not shown to suppress the occurrence of C. difficile-associated diarrhea.

Abstract
The aim of this study was to characterize immunohistochemically 18 cases of canine haemangiopericytoma (CHP) using two new candidate markers for pericytes, tumour endothelial marker (TEM)-1 and new glue (NG)-2, as well as the conventional mesenchymal cellular markers, vimentin, α-smooth muscle actin (α-SMA), desmin and von Willebrand factor (vWF). Because pericytes may have the same origin as endothelial or smooth muscle cells or the same differentiation potential as myofibroblasts, 17 cases of leiomyosarcoma (LMS), 20 cases of haemangiosarcoma (HS) and three cases of myofibroblastic sarcoma (MFS) were also examined. Expression of TEM-1 by >10% of the neoplastic population was observed in 94.4% (17/18) of haemangiopericytomas, 23.5% (4/17) of LMSs, 30.0% (6/20) of HSs and 66.7% (2/3) of MFSs. NG-2 expression by >10% of the neoplastic population was observed in 16.7% (3/18) of haemangiopericytomas, 52.9% (9/17) of LMSs, 0% (0/20) of HSs and 33.3% (1/3) of MFSs. Vimentin was expressed by all of tumours. In haemangiopericytoma, the incidence of positive immunoreactivity in >10% of the neoplastic population was 5.6% (1/18) for both α-SMA and desmin and 0% (0/18) for vWF. Considering the phenotypic features of cells expressing TEM-1, CHPs are thought to originate from immature vascular mural cells sharing their phenotype with myofibroblasts. NG-2 expression may be a phenotype of smooth muscle cells rather than pericytes in dogs.

Abstract
Proteinuria following administration of bevacizumab is reported to be a specific adverse effect, but the risk factors for proteinuria have not been elucidated. In this study, the risk factors for urinary protein expression resulting from bevacizumab combination chemotherapy were investigated. The subjects were 47 patients aged > or = 20 years who had received bevacizumab combination chemotherapy at Gifu Municipal Hospital between February 2010 and February 2011. A total of 13 patients were excluded based on exclusion criteria; of the remaining 34 patients, 24 (70.6%) were assigned to the urinary protein non-expression group, and 10 (29.4%) were assigned to the urinary protein expression group. The results of multivariate logistic regression analysis revealed a significant difference in systolic blood pressure (> or =130 mmHg) between the two groups (OR: 14.499, 95%CI: 1.326-158.577, p=0.028). This finding shows that systolic blood pressure (> or =130 mmHg) is a risk factor for urinary protein expression resulting from bevacizumab combination chemotherapy.

Abstract
Oxygen is a limiting nutrient in animal cell culture and its supply is still worthy of improvement for production of useful proteins with a high efficiency. From a different point of view, development of the system by which a high productivity can be maintained even under hypoxic condition as well as under normoxic condition may be important. A number of hypoxia-inducible genes have been found in eucaryotic cells and the induction in most cases, if not all, is due to hypoxic activation of the gene transcription. Transcription of erythropoietin gene is highly hypoxia-inducible and the induction is achieved by binding of a protein, which is widely distributed in animal cells, to a short DNA stretch (erythropoietin enhancer) in the 3' flanking region of erythropoietin gene. Using a hepatoma cell line (Hep3B) that produces the endogenous erythropoietin in an oxygen-dependent manner and Chinese hamster ovary cells that have been widely used for production of recombinant proteins, we show that, under hypoxic condition, the erythropoietin enhancer can activate not only the promoter of erythropoietin gene but also promoters of cytomegalovirus early genes and eucaryotic polypeptide chain elongation factor gene, both of which are very active in animal cells under normoxic condition.

Abstract
A subcutaneous tumour was identified in the maxillary region of a 14-year-old mixed breed dog. This tumour had grown rapidly over 2 weeks. Microscopically, the tumour had ill-defined borders and was composed of bundles and whorls of atypical spindle cells accompanied by abundant collagen fibres. Immunohistochemically, neoplastic cells were immunoreactive for vimentin, α-smooth muscle actin and calponin and negative for S100 protein, von Willebrand factor, desmin and smoothelin. These results suggested that the neoplastic cells were derived from myofibroblasts and that the tumour was a low-grade myofibroblastic sarcoma.

Abstract
Serum-free mouse embryo (SFME) cells were established by D. Barnes et al., and are known to be a neural stem cell line, which differentiate into astrocytes upon treatment with TGF-beta. Therefore, SFME cells is thought to be a model well suited to analyze the differentiation mechanism of neural stem cells. Until now, we have investigated the regulation mechanisms of telomerase activity and telomere length in human cancer and normal cells. Telomerase is the enzyme responsible for the synthesis and maintenance of telomere repeats located at chromosomal ends and is normally expressed in embryonic and germline cells, but not in most normal cells. Here, using SFME cells, we attempted to analyze the regulation mechanism of telomerase activity in neural stem cells and to detect a change upon differentiation into astrocytes. When SFME cells were cultured in the presence of TGF-beta, cells showed anelongated morphology and decreased its growth to 50% of control culture. Cells also expressed the glial fibrillary acidic protein (GFAP), a marker for astrocytes,indicating that TGF-beta induced differentiation in SFME cells from neural stem cells into astrocytes. At the same time,TGF-beta also inhibited telomerase activity and repressed the expression of the mouse telomerase reverse transcriptase(mTERT), demonstrating that SFME cells was vested with a finite replicative life span upon treatment with TGF-beta. To understand the mechanisms regulating mTERT levels during differentiation into astrocytes, we have estimated the expression level of c-myc, which is known to be a key molecule in activating the TERT promoter. As a result, TGF-beta-treated SFME cells were shown to repress the expression of c-myc. Furthermore, promoter analysis, using the 5'-region of the mTERT gene, which possess two E-box elements bound to c-Myc/Max, demonstrated that mTERT promoter activity greatly decreased in TGF-beta-treated SFME cells as compared to non-treated SFME cells. These suggest that c-myc might play a critical role in the expression of mTERT, and that down-regulation of c-myc dependent upon the astrocytic differentiation in SFME cells might cause the repression of mTERT in TGF-beta-treated SFME cells.

Abstract
AIMS The study aimed to investigate early-stage atherosclerosis in patients with impaired fasting glucose compared with patients with impaired glucose tolerance. METHODS Body mass index, systolic blood pressure, fasting plasma glucose, lipid variables, ankle-brachial pressure index and brachial-ankle pulse wave velocity were measured in 2842 subjects from Takasaki city located approximately 100 km north of Tokyo in Japan. The subjects were divided into the following five groups based on a 75-g oral glucose tolerance test: (i) normal fasting plasma glucose/normal glucose tolerance group, (ii) impaired fasting glucose group, (iii) impaired glucose tolerance group, (iv) combined glucose intolerance group and (v) diabetic glucose intolerance group. RESULTS In comparison with fasting plasma glucose levels (r = 0.269, P < 0.0001), 2-h post-challenge glucose levels were more closely correlated with pulse wave velocity values (r = 0.300, P < 0.0001). The groups with impaired glucose tolerance, combined glucose intolerance and diabetic glucose intolerance had significantly higher pulse wave velocity values compared with the groups with normal glucose tolerance and impaired fasting glucose. Multiple regression analyses showed an independent association of age, systolic blood pressures, total cholesterol, fasting and 2h plasma glucose with pulsewave velocityvalues. Furthermore, pulse wave velocity was not significantly correlated with fasting plasma glucose, but was correlated with increased 2h plasma glucose. CONCLUSIONS Groups with impaired glucose tolerance and combined glucose intolerance had significantly higher brachio-ankle pulse wave velocity values compared with the group with normal glucose tolerance. Although the group with impaired fasting glucose showed a marginal increase in pulse wave velocity values compared with the group with normal glucose tolerance, the difference was not significant. Thus impaired glucose tolerance, but not impaired fasting glucose, is a risk factor for early-stage atherosclerosis.

Abstract
Diffuse panbronchiolitis (DPB) is a rare complex genetic disease affecting East Asians and is strongly associated with the class I human leukocyte antigens (HLA)-B54 in Japanese and HLA-A11 in Koreans. We recently showed that an HLA-associated major susceptibility gene for DPB is probably located within the 200 kb in the class I region 300 kb telomeric of the HLA-B locus on the chromosome 6p21.3. We cloned two novel mucin-like genes designated panbronchiolitis related mucin-like 1 and 2 (PBMUCL1 and PBMUCL2) in the candidate region, which form a mucin-like gene cluster together with two adjacent genes, MUC21 and DPCR1. PBMUCL1 gene expression was remarkably upregulated by polyinosine-polycytidylic acid [poly(I:C)] stimulation in normal human bronchial epithelial cells redifferentiated at the air-liquid interface. We found genetic polymorphisms in PBMUCL1 gene which were associated with DPB: the A-allele of the PBMUCL1 intron 2 single nucleotide polymorphism (SNP) was positively associated and variable numbers of tandem repeats (VNTR) polymorphism in exon 3 (1,890-base pair deletion) was negatively associated. Despite a strong association with HLA-B in the Japanese, the mucin-like gene PBMUCL1 is also one of the candidate genes of DPB susceptibility.

Abstract
In recent years, bottled mineral water has undergone inactivation by methods other than the traditional heat treatment during the production process; there are fewer reports of the effectiveness of these inactivation methods on yeasts and molds in mineral water than on bacteria and protozoan oocysts. In this study, we evaluated the effects of UV irradiation and ozone treatment compared with heat treatment at 85 degrees C on yeast cells and mold spores inoculated into mineral water. A 5-log reduction occurred at a UV radiation dose of 31,433 microJ/cm2 for Saccharomyces cerevisiae and at 588,285 microJ/cm2 for Penicillium pinophilum. The treatment time for 5-log reduction estimated for UV irradiation was about 0.6 min for S. cerevisiae and about 10.7 min for P. pinophilum; at an ozone concentration of 0.1 ppm, it was 1.75 min for S. cerevisiae and 2.70 min for P. pinophilum, and at a concentration of 0.6 ppm, it was 0.32 min for S. cerevisiae and 0.57 min for P. pinophilum. Comparison of the inactivation effects among the three methods showed that UV irradiation and ozone treatment were less effective than heat treatment at 85 degrees C. Thus, when UV irradiation and ozone treatment are used for inactivation of mineral water, it seems that they need to be combined with heat treatment to achieve a definite effect. Yeast cells are more sensitive to all three inactivation methods than are mold spores, and the sensitivity of yeast cells and mold spores to these inactivation methods may vary among genera.
