Abstract
SH2-containing inositol 5'-phosphatase 2 (SHIP2) is a lipid phosphatase that negatively regulates the metabolic signalling of insulin in peripheral tissues; however, the expression of SHIP2 in the hypothalamus and its functional roles are largely unknown. In the present study, immunohistochemical analysis demonstrated that SHIP2 protein exists in neuronal cells expressing neuropeptide Y and pro-opiomelanocortin in the arcuate nucleus of the hypothalamus in C57BL/6J mice. Interestingly, the expression levels of SHIP2 in the hypothalamus were elevated in aged C57BL/6J mice and diabetic db/db mice. To clarify the significance of the increased expression of SHIP2 in the hypothalamus, we examined the central effects of insulin and leptin in transgenic mice overexpressing SHIP2 (SHIP2-Tg). Accumulation of phosphatidylinositol (3,4,5)-trisphosphate and phosphorylation of Akt in the hypothalamus, induced by i.c.v. injection of insulin, were attenuated in SHIP2-Tg compared to wild-type mice, whereas leptin-induced phosphorylation of signal transducer and activator of transcription 3 in the hypothalamus was comparable between them. The suppression of food intake after i.c.v. administration of insulin (but not leptin) was attenuated consistently in SHIP2-Tg. In addition, SHIP2-Tg showed increased food consumption after starvation and become heavier with visceral fat accumulation than wild-type mice, despite normal levels of oxygen consumption and spontaneous movement. These results suggest that SHIP2 contributes to the regulation of food intake mainly via the attenuation of insulin signalling in the hypothalamus of mice.

Abstract
We carried out arthrography in 19 thumbs of 18 patients in whom duplication was observed at the interphalangeal (Wassel type II) or metacarpophalangeal (Wassel type IV) joints on radiographs. The average age at surgery was 12.3 months and average duration of post-surgical follow-up was 21.3 months. Based on the arthrographic findings, the types of cartilaginous connections were subdivided into five groups. In group 1, there was a cartilaginous connection at the base of duplicated phalanges. In group 2, there was a cartilaginous connection of the radial digit between the distal and proximal phalanges, or between the proximal phalanx and metacarpal. In group 3, the phalanges separated at a common joint without any cartilaginous connection. In group 4, the radial digit demonstrated fibrous attachment to the capsule without any joint formation. In group 5, each joint was completely separated without any cartilaginous connection. These arthrographic findings could not be detected on radiographs. Different surgical procedures were carried out according to the form of cartilaginous connection.

Abstract
BACKGROUND/AIMS To evaluate the usefulness of flexible spectral imaging color enhancement with indigo carmine (I-FICE) in early gastric cancer (EGC) demarcation. METHODS The study participants were 29 patients with differentiated-type EGC. The endoscope was fixed and images of the same area of EGC demarcations in each lesion were obtained using four different methods (WLE, flexible spectral imaging color enhancement (FICE), CE, and I-FICE). FICE mode at R 550 nm (Gain: 2), G 500 nm (Gain: 4), and B 470 nm (Gain: 4) was used. Four endoscopists ranked the images obtained by each method on the basis of the ease of recognition of demarcation using a 4-point system. We calculated the standard deviation of pixel values based on L*, a*, and b* color spaces in the demarcation region (Lab-SD score). RESULTS The median ranking score for I-FICE images was significantly higher than that obtained from the other methods. Further, the average Lab-SD score was significantly higher for I-FICE images than for images obtained by the other methods. There was a good correlation between the ranking score and Lab-SD score. CONCLUSION EGC demarcations were most easily recognized both subjectively and objectively using I-FICE image, followed by CE, FICE and WLE images.

Abstract
BACKGROUND AND PURPOSE The relationship between white matter disruption and cognitive dysfunction of patients with mTBI in the chronic stage remains unclear. The aim of this study was to identify white matter integrity by using DTI in patients with mTBI without morphologic traumatic abnormalities seen with conventional imaging and to evaluate the association of such regions with cognitive function. MATERIALS AND METHODS Diffusion tensor images from 51 consecutive patients with mTBI without morphologic traumatic abnormalities on conventional MRI were processed, and FA maps were generated as a measure of white matter integrity. All subjects underwent cognitive examinations (MMSE and WAIS-R FIQ). Correlations between the skeletonized FA values in the white matter and the cognitive function were analyzed by using regression analysis. RESULTS In patients with mTBI, significantly decreased FA value clusters in the white matter compared with the healthy controls were found in the superior longitudinal fasciculus, superior frontal gyrus, insula, and fornix. Cognitive examination scores positively correlated with FA values in a number of regions in deep brain structures, which were anatomically close or physiologically intimate to the regions with significant FA value reduction, in patients with mTBI. CONCLUSIONS The present study shows that patients with mTBI in the chronic stage have certain regions with abnormally reduced white matter integrity in the brain. Although the clinical and pathologic-anatomic correlation of these findings remains to be elucidated, these brain regions are strongly suggested to be related to chronic persistent cognitive impairments in these patients.

Abstract
The effectiveness of screening for colorectal cancer by an immunochemical fecal occult blood test was investigated by comparing the survival time of 194 screen-detected colorectal cancer subjects (screen-detected group) with that of 352 routinely diagnosed subjects (control group). The rate of Dukes' A cancers was significantly higher in screen-detected group than in the control group (43.8% vs 16.8%, p<0.0001), whereas that of Dukes' D cancer was the opposite (5.7% vs 21.3%, p<0.0001). The survival rate for screen-detected group was higher than that for the control group (Kaplan-Meier method, p<0.0001). By a proportional hazard model with adjustment for prognostic factors except stage, the risk ratio of death from colorectal cancer was 0.40 (p=0.0007) for screen-detected group versus the control group. Therefore, the screening was suggested to be effective in survival benefit, although there might be potential biases inherent in observational studies.

Abstract
UNLABELLED Eating alone is an emerging social concern these days along with the background of serious aging population growth and increasing number of single-dwellers in Japan. However, little study is focused eating alone and its relation to the health status of community-dwelling elderly. OBJECTIVES To clarify the relations between eating alone and geriatric functions such as depression, quantitative subjective quality of life (QOL), activities of daily living (ADL) and dietary status of community-dwelling Japanese elderly. DESIGN A cross-sectional study. SETTINGS Tosa town, one of the "super-aged" towns in Japan. PARTICIPANTS The study population consisted of 856 community-dwelling elderly aged ≥65 living in Tosa town. MEASUREMENTS Eating alone and living arrangement was defined by the questionnaire. Geriatric functions were assessed by measuring activities of daily living (ADL), depressive symptom using 15-item geriatric depression scale (GDS-15), and quality of life (QOL). Food diversity was investigated as a measure of dietary quality using 11-item Food Diversity Score Kyoto (FDSK-11). Body mass index (BMI) was calculated using height and body weight during a medical assessment. RESULTS The proportion of the elderly who usually eat alone was 33.2% in this study population. Even among 697 elderly subjects who live with others, 136 persons (19.5%) ate alone. The participants who ate alone were significantly depressed according to the assessment using GDS-15 score (5.7±4.3 vs. 4.4±3.8, P<0.001). Those who ate alone have lower scores of QOL items than those who ate with others (Subjective sense of health: 52.5±21.9 vs. 55.7±20.2 P=0.035, Relationship with family: 74.1±23.5 vs. 78.9±18.6 P<0.001, Subjective happiness: 58.5±22.7 vs. 62.2±21.1 P=0.019). A significant close association was found between eating alone and lower food diversity (FDSK-11 score 9.9±1.3 vs. 10.2±1.3, P=0.002). BMI was lower in the elderly subjects who ate alone than those with others. By the multivariate analysis, depression was independently associated with eating alone in the logistic regression model adjusted for age, sex, BMI and food diversity as confounding factors (OR: 1.42, CI: 1.00-2.11, P=0.043). Food diversity was also significantly associated even after the adjustment of these confounding factors. CONCLUSION Eating alone is an important issue related to depression and QOL as well as dietary status of community-dwellingl elderly in Japan. This study shows the simple and inexpensive way "eating together" may contribute to improve depressive mood of elderly persons, with a strong message that supports of family, friends and neighbors are very important.

Abstract
BACKGROUND AND PURPOSE Restenosis after CAS is a postoperative problem, with a reported frequency of approximately 2%-8%. However differences in stent design, procedure, and the antiplatelet agent appear to affect the incidence of restenosis. We assessed the frequency of restenosis and the effect of the antiplatelet agent CLZ in preventing restenosis after CAS by the standard procedure using the CWS. MATERIALS AND METHODS Between May 2010 and October 2011, 62 lesions in 60 consecutive patients underwent CAS using the CWS at 4 medical institutions, and all patients were followed clinically and assessed by sonography, 3D-CTA, or angiography at 3 and 6 months postoperatively. Restenosis was defined as ≥50% stenosis. The incidence of restenosis and the variation in the incidence of restenosis by the difference in type of antiplatelet agent between the CLZ group (n = 30; aspirin, 100 mg, and CLZ, 200 mg) and the non-CLZ group (n = 32; aspirin, 100 mg, and clopidogrel, 75 mg [n = 29]; or ticlopidine, 100 mg [n = 2] or 200 mg [n = 1]) were retrospectively investigated. Two antiplatelet agents were given starting 1 week preoperatively until at least 3 months postoperatively. RESULTS Restenosis occurred in 5 patients (8.3%), but all were cases of asymptomatic lesions in the follow-up period. All 5 patients with restenosis were in the non-CLZ group, with no cases of restenosis in the CLZ group; the difference was significant (P = .0239). CONCLUSIONS The restenosis rate after CAS by using the CWS was 8.3%. CLZ was associated with significant inhibition of restenosis.

Abstract
The case was 11-month-old girl diagnosed as tetralogy of Fallot with severe pulmonary valve stenosis and suffering from severe cyanosis. A catheter study demonstrated pulmonary artery (PA) was well arborized, but severely hypoplastic in spite of previous transcatheter pulmonary valve dilatation; PA index was calculated as 69 mm²/m². A central end-to-side aorta to PA shunt was created. Cyanosis was well improved, but congestive heart failure occurred after 1 month from the operation. Subsequent catheter study demonstrated pulmonary artery growth, 166 mm²/m² of PA index and major aortopulmonary collateral artery (MAPCA) coil embolization was performed. Patient underwent Rastelli type definitive repair 9 month after palliation. The central end-to-side aorta to PA shunt is reported as useful measure for promoting PA size increase and definitive repair achievement in patient with pulmonary atresia, ventricular septal defect and severely hypoplastic PA. Appropriate consideration of criteria, carefull follow up and treatments are necessary.

Abstract
Thumb in the plane of the hand (TPH) is a congenital deformity in which the nail plane of the radial-most digit is parallel to that of other digits, but structurally the digit retains the characteristics of a thumb. Four hands from four patients were retrospectively diagnosed as having TPH, with the underlying congenital conditions being symbrachydactyly, cleft hand and constriction band syndrome. Thumb web-plasty was carried out in all hands; one required additional rotation osteotomy of the metacarpal. Postoperative hand function was markedly improved and pinch function was possible in all cases. In most cases of TPH, the thumb has the potential to act in opposition, indicating that a thumb web-plasty is worth considering as an initial procedure.

Abstract
Diffusion-weighted images based on magnetic resonance reveal the microstructure of tissues by monitoring the random movement of water molecules. In this study, we investigated whether this new technique could visualize pathologic lesions on ulnar nerve in cubital tunnel. Six elbows in six healthy males without any symptoms and eleven elbows in ten patients with cubital tunnel syndrome underwent on diffusion-weighted MRI. No signal from the ulnar nerve was detected in normal subjects. Diffusion-weighted MRI revealed positive signals from the ulnar nerve in all of the eleven elbows with cubital tunnel syndrome. In contrast, conventional T2W-MRI revealed high signal intensity in eight elbows and low signal intensity in three elbows. Three elbows with low signal MRI showed normal nerve conduction velocity of the ulnar nerve. Diffusion-weighted MRI appears to be an attractive technique for diagnosis of cubital tunnel syndrome in its early stages which show normal electrophysiological and conventional MRI studies.

Abstract
Basophils are evolutionarily conserved in many animal species, in spite of the fact that they account for <1% of peripheral blood leukocyte. This suggests that basophils have an indispensable and nonredundant role in vivo, even though they show some phenotypic similarity with tissue-resident mast cells. However, their functional significance remained uncertain long after Paul Ehrlich discovered them as blood-circulating cells with basophilic granules more than 130 years ago. The study of basophils has been far behind that of mast cells, owing to the rarity of basophils and the paucity of tools for their detection and functional analysis. Recent development of novel analytical tools, including basophil-depleting antibodies and genetically engineered mice deficient only in basophils, has greatly advanced basophil research and illuminated previously unrecognized roles of basophils. We now appreciate that basophils and mast cells play distinct roles in immune responses. Basophils have crucial roles in the development of acute and chronic allergic responses, the protective immunity against ecto- and endoparasites, and the regulation of acquired immunity, including the augmentation of humoral memory responses and the initiation of Th2 responses. Thus, basophils are no longer the neglected minority and are key players in the immune system.

Abstract
Angiogenesis inhibitors are a novel class of promising therapeutic agents for treating cancer. TNP-470, a systemic analogue
of fumagillin, is an angiogenesis inhibitor capable of suppressing the tumorigenicity in several animal models even though
the mechanisms of action have not been completely clarified. In the current study, we investigated the effects of TNP-470
on human fibrosarcoma cells in vivo and in vitro. The administration of TNP-470 could suppress the tumorigenicity of
HT1080 fibrosarcoma tumor. The conditioned medium from HT1080 fibrosarcoma cells treated with TNP-470 inhibited
the proliferation and migration of human endothelial cell line, HUVEC and ECV304. The concentration of VEGF in the
conditioned medium from HT1080 cells treated with TNP-470 was lower than that of the cells without TNP-470 treatment,
indicating that TNP-470 downregulates the secretion of VEGF from HT1080 cells. These findings strongly suggest that the
direct action of TNP-470 on sarcoma cells inhibits angiogenesis through the downregulation of VEGF secretion and this
angiogenesis suppression resulted in the inhibition of tumorigenicity of HT1080 fibrosarcoma tumo.

Abstract
Prostate cancers generally become androgen-independent and resistant to hormone therapy with progression. To understand the underlying mechanisms and facilitate the development of novel treatments for androgen-independent prostate cancer, we have investigated plasma membrane-associated sialidase (NEU3), the key enzyme for ganglioside hydrolysis participating in transmembrane signaling. We have discovered NEU3 to be upregulated in human prostate cancer compared with non-cancerous tissue, correlating with the Gleason score. NEU3 silencing with siRNA in prostate cancer PC-3 and LNCaP cells resulted in increased expression of differentiation markers and in cell apoptosis, but decrease in Bcl-2 as well as a progression-related transcription factor, early growth response gene (EGR-1). In androgen-sensitive LNCaP cells, forced overexpression of NEU3 significantly induced expression of EGR-1, androgen receptor (AR) and PSA both with and without androgen, the cells becoming sensitive to androgen. The NEU3-mediated induction was abrogated by inhibitors for PI-3 kinase and MAP kinase and more specifically by their silencing in the absence of androgen, being confirmed by increased phosphorylation of AKT and ERK1/2 in NEU3 overexpressing cells. NEU3 siRNA introduction caused reduction of cell growth of an androgen-independent PC-3 cells in culture and of transplanted tumors in nude mice. These data suggest that NEU3 regulates tumor progression through AR signaling, and thus be a potential tool for diagnosis and therapy of androgen-independent prostate cancer.

Abstract
AIM This study assessed whether or not elevated serum uric acid can predict impaired fasting glucose (IFG) and type 2 diabetes mellitus (T2DM) in Japanese people undergoing health checkups. METHODS Altogether, 7114 male and 5529 female participants in both 2000 and 2005 were targeted for the study. After excluding those with IFG and T2DM, multiple logistic-regression analyses of 6408 men and 5309 women-average ages 48.4±10.2 and 50.0±9.1 years, respectively-were performed to identify independent risk factors for newly diagnosed IFG and T2DM in 2005, after adjusting for age, parental history of diabetes, body mass index (BMI), elevated blood pressure or hypertension, fatty liver, hypertriglyceridaemia, alcohol consumption and smoking status. RESULTS Prevalence rates for IFG and T2DM, and values for BMI, systolic and diastolic blood pressure, fasting blood glucose and triglycerides, showed significantly increasing trends in relation to serum uric acid quartiles in both genders. IFG and T2DM were newly diagnosed in 8.1% of men and 4.0% of women in 2005. Using multivariate models, the highest quartile of serum uric acid and increases in serum uric acid were independent risk factors, but only in women. Serum uric acid was not a risk factor in men when categorized by the cut-off values of 4.8 mg/dL, the limit for the highest quartile in women, and of 7.0 mg/dL. CONCLUSION Elevated serum uric acid predicted IFG and T2DM only in Japanese women undergoing regular health checkups.

Abstract
ABSTRACTThis paper describes a new organic nonlinear material, piperoniridene ethyl cyano acetate which shows short cut-off wavelength, good nonlinearity (better than POM in powder) and good crystallinity. These features of this compound encourage its application in second harmonic generation (SHG) coupled with semiconductor laser.

Abstract
BACKGROUND Proton pump inhibitors (PPIs) are less effective in non-erosive reflux disease (NERD) patients than in reflux oesophagitis patients. Whether the addition of prokinetics to PPIs improves NERD patients' symptoms remains unknown. AIM To evaluate the efficacy of mosapride in NERD patients when used with PPI. METHODS A total of 200 NERD patients were randomised to one of two arms: omeprazole (10 mg once daily) plus mosapride citrate (5 mg three times a day) (treatment arm) and omeprazole plus placebo (placebo arm). The primary endpoint was the rate of responders [visual analogue scale (VAS) was zero or <1 cm] after 4 weeks of treatment. The secondary endpoints were changes in the VAS score and the safety profile. RESULTS There was no significant difference between the rates of responders in both arms in intent-to-treat (ITT) and per-protocol (PP) analysis. The change in the VAS score in treatment arm was significantly better than placebo arm in PP analysis (-4.0 ± 0.2 and -3.3 ± 0.2, mean ± S.E.M.) (N.S. in ITT analysis). The rate of adverse events was similar in both groups. CONCLUSION The addition of mosapride to omeprazole was not more effective than omeprazole alone.

Abstract
Dravet syndrome (severe myoclonic epilepsy in infancy) is an epileptic syndrome with various types of seizures that begin in the first year of life and may result in intellectual impairment. Mutations of the SCN1A gene are the most prevalent genetic cause of Dravet syndrome. In this study, we report a 12-year-old girl with Dravet syndrome carrying an SCN1A mutation, c.2785Cdel (L929del fsX934). She had an episode of status epilepticus and persistent lethargy after 48 h of acute febrile illness that was preceded by an annual flu vaccination. Low voltage activities detected by electroencephalogram and elevated neuron-specific enolase/interleukin-6 concentrations in the cerebrospinal fluid suggested acute encephalopathy. MRI showed abnormalities in the bilateral thalami, cerebellum and brainstem. These abnormalities were protracted over a month. The biochemical and MRI characteristics of this case are different from any known type of encephalopathy, and may suggest a vulnerability of neurons expressing mutant SCN1A in the brain.

Abstract
OBJECTIVE Injection of complete Freund's adjuvant (CFA) into the temporomandibular joint (TMJ) causes acute swelling around the joint and subsequent morphological alterations in the condyle. We aimed to evaluate changes in the three-dimensional architecture of the condyle induced with CFA. MATERIALS AND METHODS The CFA was injected into the unilateral TMJ of rats and morphological changes in the condyle were assessed repeatedly for 14 days by in vivo micro-CT. RESULTS Osseous abnormalities of condyle were first observed at 3-5 days after CFA injection on the tomographic images, and the condylar deformation became more obvious thereafter. Among 12 condyles examined at 14 days postinjection, osteophytosis was observed in all of the specimens and bone erosion coexisted in five condyles. None of the saline-treated condyles showed architectural changes. Significant changes were detected in the mesiolateral and rostrocaudal widths of the CFA-treated condyles at 10-14 days postinjection (P < 0.01). The extent of both condylar bone formation and resorption was greater in the CFA-injected TMJs than in saline-injected TMJs (P < 0.05). CONCLUSION These results indicate that CFA causes dynamic morphological changes in the condyle and that our experimental approach will provide new insights into the subacute inflammatory processes in the TMJ.

Abstract
To estimate the current population genetic structure of Mycobacterium tuberculosis in Japan, phylogenetic traits were analysed for 237 Beijing family strains isolated from tuberculosis patients throughout the country. Unlike previous reports from other countries, the ancient Beijing sublineage was predominant throughout Japan. Clustering analysis based on JATA-VNTR (Japan Anti-Tuberculosis Association variable numbers of tandem repeats), a specialised set of VNTR for the discrimination of Japanese M. tuberculosis strains, revealed high similarity of the modern Beijing sublineage strains, irrespective of their geographic origin. JATA-VNTR might be useful for the phylogenetic classification in populations where ancient Beijing strains are frequently isolated.

Abstract
BACKGROUND Short-chain fatty acids such as lactic acid produced by the intestinal bacterial flora have various physiological actions involved in health, and it is important to determine the concentrations of faecal short-chain fatty acids and evaluate their relationship with large intestinal diseases. In this study, we evaluated the highly selective and sensitive simultaneous measurement of both volatile and non-volatile short-chain fatty acid hydrazides using high-performance liquid chromatography (HPLC). MATERIALS AND METHODS Faeces treated with ethanol were used as analytic samples. Short-chain fatty acids were measured as fatty acid hydrazides by HPLC. RESULTS For 12 types of short-chain fatty acid, the results regarding linearity, recovery tests and reproducibility were favourable. Faeces treated with ethanol could be stored at room temperature. DISCUSSION The stability of short-chain fatty acids in faeces at room temperature was statistically analysed. Faeces stored without treatment with ethanol showed increases/decreases in the concentrations of short-chain fatty acids, which may be due to assimilation by intestinal bacteria. However, specimen in 70% ethanol and stored in room temperature exhibited no substantial changes in concentrations of short-chain fatty acids up to seven days.

Abstract
CD44 is a highly glycosylated cell adhesion molecule that is involved in lymphocyte infiltration of inflamed tissues. We have demonstrated previously that sialic acid residues of CD44 negatively regulates its receptor function and CD44 plays an important role in the accumulation of T helper type 2 (Th2) cells in the airway of a murine model of acute asthma. Here we evaluated the role of sialidase in the hyaluronic acid (HA) receptor function of CD44 expressed on CD4+ T cells, as well as in the development of a mite antigen-induced murine model of acute asthma. Splenic CD4+ T cell binding of HA was examined with flow cytometry. Expression of sialidases (Neu1, Neu2, Neu3 and Neu4) in spleen cells was evaluated by quantitative real-time reverse transcription-polymerase chain reaction. Airway inflammation and airway hyperresponsiveness (AHR) were evaluated in the asthmatic Neu1-deficient mouse strain SM/J model. Splenic CD4+ T cells from asthmatic model mice displayed increased HA receptor activity of CD44 after culture with the antigen, along with characteristic parallel induction of sialidase (Neu1) expression. This induction of HA binding was suppressed significantly by a sialidase inhibitor and was not observed in SM/J mice. Th2 cytokine concentration and absolute number of Th2 cells in the bronchoalveolar lavage fluid, and AHR were decreased in SM/J mice. In conclusion, HA receptor activity of CD44 and acute asthmatic reactions, including Th2-mediated airway inflammation and AHR, are dependent upon Neu1 enzymatic activity. Our observation suggests that Neu1 may be a target molecule for the treatment of asthma.

Abstract
BACKGROUND Theophylline has an anti-inflammatory action that may account for its clinical effectiveness in the reduction of inflammatory cells in the airways. Dendritic cells (DCs) are professional antigen-presenting cells, capable of priming naïve T cells, and play key roles in the activation of immune responses in asthma. OBJECTIVE The purpose of this study was to investigate the effects of theophylline on human monocyte differentiation into DCs and whether this involved antagonism of adenosine receptors. METHODS Peripheral human blood monocytes were cultured in the presence of granulocyte/macrophage-colony stimulating factor and IL-4 to induce DC differentiation. The cells were incubated with theophylline, KF17837 (a selective A2a receptor antagonist) and enprofylline (A2b receptor antagonist) and co-incubated with selective adenosine A1 and A2a receptor agonists, a phosphodiesterase inhibitor (rolipram) and adenosine deaminase (ADA) to determine their effects on DC differentiation. In addition, depletion of adenosine receptors by small interfering RNA (siRNA) was also examined. RESULTS Monocytes differentiated into myeloid DCs in the culture system. The number of DCs was remarkably reduced by 60-70% when theophylline was administered at a therapeutic concentration. This effect was concentration-dependently exacerbated, was partly mediated by cellular apoptosis and was effectively reversed by the addition of the A1 agonists [2-chloro-N(6)-cyclopentyladenosin, N(6)-cyclohexyladenosine, and N-ethylcarboxamidoadenosine (NECA)] or the A2a agonist (CGS-21680, NECA). The depletion of the adenosine A1 receptor by siRNA and addition of ADA remarkably reduced DC differentiation. Meanwhile, both enprofylline and rolipram had little effect. CONCLUSION Our findings suggest that the adenosine A1 (and possibly coordinated with A2a) receptors contribute to DC differentiation and survival. These findings provide further evidence that theophylline has an anti-inflammatory action in bronchial asthma.

Abstract
Orexin-A (hypocretin-1) and orexin-B (hypocretin-2) are hypothalamic neuropeptides that play key roles in the regulation of wakefulness, feeding, reward, autonomic functions and energy homeostasis. To control these functions indispensable for survival, orexin-expressing neurones integrate peripheral metabolic signals, interact with many types of neurones in the brain and modulate their activities via the activation of orexin-1 receptor or orexin-2 receptor. In addition, a new functional role of orexin is emerging in the regulation of insulin and leptin sensitivities responsible for whole-body glucose metabolism. Recent evidence indicates that orexin efficiently protects against the development of peripheral insulin resistance induced by ageing or high-fat feeding in mice. In particular, the orexin receptor-2 signalling appears to confer resistance to diet-induced obesity and insulin insensitivity by improving leptin sensitivity. In fact, the expression of orexin gene is known to be down-regulated by hyperglycaemia in the rodent model of diabetes, such as ob/ob and db/db mice. Moreover, the levels of orexin receptor-2 mRNA have been shown to decline in the brain of mice along with ageing. These suggest that hyperglycaemia due to insulin insensitivity during ageing or by habitual consumption of a high-fat diet leads to the reduction in orexin expression in the hypothalamus, thereby further exacerbating peripheral insulin resistance. Therefore, orexin receptor controlling hypothalamic insulin/leptin actions may be a new target for possible future treatment of hyperglycaemia in patients with type 2 diabetes.

Abstract
Thalidomide is an effective drug for chronic inflammatory diseases, but the mechanism underlying its immunomodulatory action remains uncertain. Thalidomide has been reported to clinically improve chronic inflammatory granulomatous disorders. In such disorders, the granulomas consist of epithelioid cells, scattered lymphocytes and multinucleated giant cells (MNGC; Langhans-type cells). The present experimental approach permitted the reproduction of MNGC formation from peripheral blood monocytes and examination of thalidomides effect on it. MNGC can be effectively generated from monocytes cultured in the presence of interleukin-4 (IL-4) and macrophage colony-stimulating factor(M-CSF) for 14 days. Thalidomide can inhibit the formation of MNGC in a dose-dependent manner. MNGC formation was partly inhibited by the presence of neutralizing TNF-alpha antibody in the responses induced by IL-4 and M-CSF. Autocrinal TNF-alpha production and modulation of cadhelin expression to regulate cell adhesion might be involved in this inhibitory action of thalidomide. Our results support thalidomides clinical efficacy in the treatment of chronic granulomatous disorders (granulomatosis).

Abstract
Background: Several human cancers have been found to contain cancer stem-like cells (CSCs) having cancer-initiating ability. However, only a few reports have shown the existence of CSCs in bone and soft tissue sarcomas. In this study, we identified and characterised side population (SP) cells that showed drug-resistant features in human bone sarcoma cell lines. Methods: In seven osteosarcoma cell lines (OS2000, KIKU, NY, Huo9, HOS, U2OS and Saos2) and in one bone malignant fibrous histiocytoma (MFH) cell line (MFH2003), the frequency of SP cells was analysed. Tumourigenicity of SP cells was assessed in vitro and in vivo. Gene profiles of SP cells and other populations (main population; MP) of cells were characterised using cDNA microarrays. Results: SP cells were found in NY (0.31%) and MFH2003 (5.28%). SP cells of MFH2003 formed spherical colonies and re-populated into SP and MP cells. In an NOD/SCID mice xenograft model, 1 × 103 sorted SP cell-induced tumourigenesis. cDNA microarray analysis showed that 23 genes were upregulated in SP cells. Conclusions: We showed that SP cells existed in bone sarcoma cell lines. SP cells of MFH2003 had cancer-initiating ability in vitro and in vivo. The gene profiles of SP cells could serve as candidate markers for CSCs in bone sarcomas.
