Abstract
BACKGROUND Diabetic foot ulcers (DFUs) are a devastating complication of diabetes. OBJECTIVES To identify genetic contributors to the development of DFUs in the presence of peripheral neuropathy in a Scottish cohort with diabetes using a genome-wide association study. METHODS A genome-wide association approach was applied. A case was defined as a person with diabetes (type 1 or type 2) who had ever had a foot ulcer (current or previous) in at least one foot, as well as a positive monofilament test result (i.e. evidence of peripheral neuropathy) recorded in their longitudinal e-health records. A control was defined as an individual with diabetes (type 1 or type 2) who has never been recorded as having a foot ulcer in either foot but who had a positive monofilament test result recorded in either foot in their longitudinal e-health records. RESULTS There were 699 DFU cases and 2695 controls in the Genetics of Diabetes Audit and Research in Tayside Scotland (GoDARTS) dataset. The single-nucleotide polymorphism rs80028505 (Chr6p21·31) in MAPK14 reached genome-wide significance with a lowest P-value of 2·45 × 10-8 . The narrow-sense heritability of this phenotype is 0·06. CONCLUSIONS We suggest that MAPK14 is associated with DFUs.

Abstract
We present a new stacked TunaDrive motor with two intact piezoelectric stacks being spring-clamped by a pair of parallel highly polished zirconia ceramic rods. Compared with the earlier version we presented with five stacks, it has a simpler and more compact structure and is much easier to build. Although the usage of piezoelectric material is cut by ∼35%, the motor can still provide a large output force of ∼1.92 N, which is nearly the same as that of the earlier version. The simple and symmetrical structure, high rigidity, and large output force make the new motor an ideal tool for coarse approach with nanometer precision.

Abstract
Objective:This paper discusses the expression and significance of CD4⁺CD25⁺ Tregs and Foxp3 in peripheral blood of patients with head and neck squamous cell carcinoma. Method:We have collected 40 cases of head and neck squamous cell carcinoma patients with newly diagnosed or relapse after treatment, all of them underwent surgery, 39 males and 1 females, aged 41-79 years, in our department from January 2014 to December 2015. At the same time, 10 healthy volunteers are enrolled as control group. 2 ml peripheral blood has been detected by flow cytometry, and the ratio of CD4⁺CD25⁺/CD4⁺ and CD4⁺CD25⁺Fxop3⁺/CD4⁺ are calculated, respectively. SPSS 23.0 is used for statistical analysis. Result:CD4⁺CD25⁺ Tregs is highly expressed in head and neck tumors, compared with that in the healthy control, and the difference is statistically significant (P<0.01). There is significant difference between the early and late stage (P<0.05). The positive rate of Foxp3+ is higher in CD4⁺CD25⁺ Tregs positive cells than in control group (P<0.01). The difference of positive rate between late stage and early stage head and neck tumors is statistically significant (P<0.05). There is a significant positive correlation between CD4⁺CD25⁺ Tregs and Foxp3 (r=0.95). Conclusion:CD4⁺CD25⁺ Tregs and Foxp3 are highly expressed in the peripheral blood of patients with head and neck squamous cell carcinoma. Through the inhibition of the immune system in patients with head and neck squamous cell carcinoma, the development of carcinoma were promoted.

Abstract
We design and fabricate an aplanatic double liquid-core cylindrical lens (DLCL), which is used to measure the binary liquid diffusion coefficient (D). The front lens of the DLCL is used as both a diffusion cell and a key imaging element; the refractive index (RI) of liquid filled in its core can be measured in the way of spatial resolution. The rear lens of the DLCL is used as an aplanatic component, and either the RI position of spherical aberration (SA) or the SA in a range of RI caused by the front lens can be regulated by selecting the liquid, of which RI is pre-prepared and filled in the rear liquid core. Equipped with the aplanatic DLCL, two methods have been applied to measure the D value of 0.33mol/L KCL aqueous solution at temperature 298.15K. The first method derives D value precisely from the drift rate of diffusion image and the measured D is 1.8508 × 10-5 cm2/s. Meanwhile, the second method obtains the D value rapidly by analyzing an instantaneous diffusion image and the measured D is 1.8619 × 10-5 cm2/s. The measured values are in good agreement with the literature value, demonstrating that the designed DLCL works well in measuring liquid diffusion coefficients.

Abstract
This work aimed to analyze the effect of deep infiltrating endometriosis (DIE) in young women. Twenty-seven cases of patients (below 38-years-old) diagnosed with DIE and admitted to the present hospital from January 2008 to July 2014 were reviewed, and their pre- and postoperative states of illness were summarized. The main preoperative symptoms included dysmenorrhea, chronic pelvic pain, dyspareunia, nodule in rectouterine fossa, and reduced level of fertility. All patients underwent surgery (17 laparoscopies and ten laparotomies). Postoperative pathological explanation confirmed DIE in lesions. DIE significantly affects the health of young women.

Abstract
Despite the inherent problems associated with in vivo animal models of tumor growth and metastases, many of the current in vitro brain tumor models also do not accurately mimic tumor-host brain interactions. Therefore, there is a need to develop such co-culture models to study tumor biology and, importantly, the efficacy of drug delivery systems targeting the brain. So far, few investigations of this nature have been published. In this paper we describe the development of a new model system and its application to drug delivery assessment. For our new model, a co-culture of DAOY cell brain tumor aggregates and organo-typic brain slices was developed. Initially, the DAOY aggregates attached to cerebellum slices and invaded as a unit. Single cells in the periphery of the aggregate detached from the DAOY aggregates and gradually replaced normal brain cells. This invasive behavior of DAOY cells toward organotypic cerebellum slices shows a similar pattern to that seen in vivo. After validation of the co-culture model using transmission electron microscopy, nanoparticle (NP) uptake was then evaluated. Confocal micrographs illustrated that DAOY cells in this co-culture model took up most of the NPs, but few NPs were distributed into brain cells. This finding corresponded with results of NP uptake in DAOY and brain aggregates reported elsewhere.

Abstract
A new experiment is described to detect a permanent electric dipole moment of the proton with a sensitivity of 10-29 e ⋅ cm by using polarized "magic" momentum 0.7 GeV/c protons in an all-electric storage ring. Systematic errors relevant to the experiment are discussed and techniques to address them are presented. The measurement is sensitive to new physics beyond the standard model at the scale of 3000 TeV.

Abstract
OBJECTIVE To understand the association between IKZF3 gene polymorphism and the risk of systemic lupus erythematosus(SLE)in Han ethnic group in southern China. METHODS A case-control study was conducted among 213 SLE patients and 234 healthy controls. Venous blood samples were collected from them to measure single nucleotide polymorphism(SNP)in IKZF3 by using the method of restriction fragment length polymorphism(PCR-RFLP). Multivariate logistic analysis and generalized multifactor dimensionality reduction(GMDR)method were used under multiple genetic models(additive, dominant, recessive), to analyze the association between IKZF3 and SLE susceptibility or different clinical features and gene-gene interactions. In addition, bioinformatics analysis was also conducted. RESULTS As for rs114509391, CA genotype might decrease the risk of SLE compared with AA genotype(OR=0.14, 95%CI: 0.03-0.56, P=0.006)and significant association was also observed under dominant model(OR=0.26, 95%CI: 0.09-0.81, P=0.02). Stratified analysis indicated that rs9635726 and rs9909593 were related to SLE onset. The study of clinical features showed that rs907091 was associated with both renal disorder(additive: OR=0.59, 95%CI: 0.35-0.98, P=0.043)and anti-SSB(dominant: OR=0.41, 95%CI: 0.18-0.96, P=0.040). rs9635726 GG and GA genotype might decrease the risk of anti-SSB compared with AA genotype(OR=0.37, 95%CI:0.16-0.88, P=0.025). In addition, bioinformatics analysis indicated that all the studied SNPs were functional. CONCLUSION IKZF3 rs114509391, rs9635726 and rs9909593 polymorphisms might be related to SLE susceptibility in Han ethnic group in southern China and rs9909593, rs907091 might be associated with renal disorder and anti-SSB.

Abstract
Background Neuropathic pain, caused by a lesion or a disease affecting the somatosensory system, is one of the most common complications in diabetic patients. The purpose of this study is to identify genetic factors contributing to this type of pain in a general diabetic population. Method We accessed the Genetics of Diabetes Audit and Research Tayside (GoDARTS) datasets that contain prescription information and monofilament test results for 9439 diabetic patients, among which 6927 diabetic individuals were genotyped by Affymetrix SNP6.0 or Illumina OmniExpress chips. Cases of neuropathic pain were defined as diabetic patients with a prescription history of at least one of five drugs specifically indicated for the treatment of neuropathic pain and in whom monofilament test result was positive for sensory neuropathy in at least one foot. Controls were individuals who did not have a record of receiving any opioid analgesics. Imputation of non‐genotyped SNPs was performed by IMPUTE2, with reference files from 1000 Genomes Phase I datasets. Results After data cleaning and relevant exclusions, imputed genotypes of 572 diabetic neuropathic pain cases and 2491 diabetic controls were used in the Fisher's exact test. We identified a cluster in the Chr8p21.3, next to GFRA2 with a lowest p‐value of 1.77 × 10−7 at rs17428041. The narrow‐sense heritability of this phenotype was 11.00%. Conclusion This genome‐wide association study on diabetic neuropathic pain suggests new evidence for the involvement of variants near GFRA2 with the disorder, which needs to be verified in an independent cohort and at the molecular level.

Abstract
We demonstrate the polarization mode selection and the dependence of coupling efficiency on polarization state of pump light for an optofluidic ring resonator (OFRR) laser. An optical fiber is chosen to serve as the ring resonator and surrounded by rhodamine 6G dye solution of lower refractive index as the fluidic gain medium. When the ring resonator is pumped by a linearly s-polarized laser, the emitted whispering gallery mode (WGM) lasing is of parallel polarization (TM mode), while p-polarized laser excitation generates a vertically polarized lasing emission (TE mode), both TM and TE mode lasing emission coexist simultaneously if the ring resonator is pumped by the s- and p-mixed polarized light. Further investigation reveals that the lasing intensity of the TM mode is approximately twice that of the TE mode for the same pump energy density, meaning an obvious difference of coupling efficiency on the polarization state of pump light; the experimental results of coupling efficiency are well explained by an induced dipole model.

Abstract
This study aimed to explore the correlations between cadherin-17 (CDH17) protein expression and the clinicopathological features and prognosis of patients with sporadic gastric cancer (GC). Nine relevant studies of 1,960 patients were identified using electronic database searches supplemented with a manual search in strict accordance with inclusion and exclusion criteria. Statistical analyses were conducted using STATA 12.0 statistical software. Relative risks and 95% confidence intervals were determined, and Z test was used to measure the significance of the overall effect size. A total of nine eligible cohort studies were included in this meta-analysis. The expression of CDH17 in patients with diffuse GC was significantly higher than in those with intestinal-type GC. Moreover, the tumor depth of invasion differed significantly between patients with positive CDH17 (CDH17+) and negative CDH17 (CDH17-) GC. However, there were no significant differences between CDH17+ and CDH17- GC patients with respect to tumor node metastasis clinical stages, histological grades, or lymph node metastasis. Despite the differences in invasive depth, there was no significant difference in 5-year survival rates between CDH17+ and CDH17- GC patients. Our meta-analysis provides evidence that CDH17 protein expression may be associated with the development of GC, suggesting that CDH17 is an important biomarker that could be useful for the early diagnosis of GC. However, CDH17 levels do not appear to impact overall survival.

Abstract
A novel optical method was applied to measure the binary liquid diffusion coefficient (D) quickly. Equipped with an asymmetric liquid-core cylindrical lens (ALCL), the spatially resolving ability of the ALCL in measuring refractive index of liquid was utilized to obtain the gradient distribution of the liquid concentration along diffusive direction. Based on Fick's second law, the D value was then calculated by analyzing diffusion images. It was worth mentioning that only one instantaneous diffusive image was required to measure D value by the method, reducing the measurement time greatly from several hours in traditional methods to a few seconds. The diffusion coefficients of ethylene glycol diffusing in pure water, at temperatures from 288.15 to 308.15 K, were measured by analyzing instantaneous diffusion images, the results were consistent well with the values measured by using holographic interferometry and Taylor dispersion methods. The method is characterized by faster measurement, direct observation of diffusive process, and easy operation, which provides a new method in measuring diffusion coefficient of liquids rapidly.

Abstract
BACKGROUND Interleukin (IL)-6, an important proinflammatory cytokine, plays a potential pathological role in systemic lupus erythematosus (SLE). Studies on the relationship of IL-6 gene polymorphisms with SLE are inconclusive. The aim of this study was to estimate the relationship more precisely. METHODS The databases of PubMed and Web of Science updated to 30 August 2014 were retrieved. Meta-analysis was conducted using allelic contrast, dominant, recessive and homozygote contrast models. Fifteen studies were included in this study and ethnicity-specific meta-analysis was performed on European, Iranian and Asian populations. RESULTS Analysis for the IL-6-174 G/C polymorphism under all models except the homozygote contrast model indicated an association in the overall population (allelic contrast model: odds ratio (OR) 1.428, 95% confidence interval (CI) 1.124-1.812, dominant model: OR 1.382, 95% CI 1.037-1.842, recessive model: OR 1.610, 95% CI 1.158-2.240, homozygote contrast model: OR 1.759, 95% CI 0.989-3.127), as well as in European individuals under all four genetic models (allelic contrast model: OR 1.557, 95% CI 1.155-2.098, dominant model: OR 1.699, 95% CI 1.203-2.400, recessive model: OR 1.506, 95% CI 1.176-1.930, homozygote contrast model: OR 2.118, 95% CI 1.103-4.065). Analysis for the IL-6-572 G/C polymorphism indicated significant association in overall ethnicities under the recessive model (OR 1.491, 95% CI 1.104-2.014), but not under other models or in Asian individuals. In addition, significant association between the IL-6-174 G/C polymorphism and discoid skin lesions and antinuclear antibodies (ANAs) were found under the allelic contrast model and recessive model, respectively (discoid skin lesions: OR 2.271, 95% CI 1.053-4.895; ANAs: OR 2.244, 95% CI 1.141-4.416). CONCLUSION This meta-analysis provides evidence of the association between the IL-6 polymorphism and the risk of SLE, hinting that the IL-6-174 G/C and IL-6-572 G/C polymorphisms may play a role in SLE susceptibility.

Abstract
OBJECTIVE This study was performed to evaluate the effect of mammary serine protease inhibitor (maspin) overexpression on human cervical squamous carcinoma (SCC) SiHa cell proliferation and apoptosis in vitro. MATERIAL AND METHODS Recombinant plasmid pcDNA3-maspin was stably transfected into human cervical SCC SiHa cell. Maspin mRNA was determined by RT-PCR, whereas maspin protein was detected by Western blot analysis and immunocytochemistry (IHC). Cell proliferation activity was measured by MTT method. Apoptosis rate and cell cycle distribution were detected by flow cytometry to understand the changes in the cell biological characteristics. RESULTS The strengthened expression of the maspin gene in the SiHa cell was confirmed by RT-PCR, Western blot, and immunocytochemistry (IHC) (p < 0.05). Suppressed proliferation activity and increased apoptosis rate of SiHa-m (maspin stable transfected) versus SiHa and SiHa-vector cell (SiHa-pc3) were shown by MTT and flow cytometry (p < 0.05). SiHa and SiHa-pc3-had no statistical significance (p > 0.05). CONCLUSION The results showed that maspin gene can significantly inhibit human cervical SCC SiHa cell proliferation and effectively slow cancer growth. Maspin may be a new molecular target in the gene therapy of human cervical SCC.

Abstract
The effects of endogenous cortisol on binucleate cells (BNCs), which promote fetal growth, may be mediated by glucocorticoid receptors (GRs), and exposure to dexamethasone (DEX) in early pregnancy stages of placental development might modify this response. In this article, we have investigated the expression of GR as a determinant of these responses. Pregnant ewes carrying singleton fetuses (n = 119) were randomized to control (2 mL saline/ewe) or DEX-treated groups (intramuscular injections of 0.14 mg/kg ewe weight per 12 hours) at 40 to 41 days of gestation (dG). Placental tissue was collected at 50, 100, 125, and 140 dG. Total glucocorticoid receptor protein (GRt) was increased significantly by DEX at 50 and 125 dG in females only, but decreased in males at 125 dG as compared to controls. Glucocorticoid receptor α (GRα) protein was not changed after DEX treatment. Three BNC phenotypes were detected regarding GRα expression (++, +-, --), DEX increased the proportion of (++) and decreased (--) BNC at 140 dG. Effects were sex- and cell type dependent, modifying the responsiveness of the placenta to endogenous cortisol. We speculate that 3 maturational stages of BNCs exist and that the overall activity of BNCs is determined by the distribution of these 3 cell types, which may become altered through early pregnancy exposure to elevated glucocorticoids.

Abstract
Background: NKG2D recognises several ligands, including polymorphic major histocompatibility complex class I chain-related chain-related proteins A and B (MICA/B) and unique long 16-binding proteins (ULBPs). These ligands are present on cancer cells and are recognised by NKG2D in a cell-structure-sensing manner, triggering natural killer (NK) cell cytotoxicity. However, the mechanisms that control the expression of NKG2D ligands in malignant cells are poorly understood. 1-α,25-Dihydroxyvitamin D3 (1,25(OH)2D3) was recently shown to enhance the susceptibility of melanoma cells to the cytotoxicity of NK cells. However, the function of 1,25(OH)2D3 in other cancers and its potential mechanisms of action remain unknown. Methods: The expression levels of miR-302c and miR-520c in Kasumi-1, K562, MCF7 and MDA-MB-231 cells were evaluated using quantitative real-time PCR. The targets of miR-302c and miR-520c were confirmed by luciferase reporter assay. The killing effects of NK92 cells against Kasumi-1, K562, MCF7 and MDA-MB-231 cells were examined using the CytoTox 96 Non-Radioactive Cytotoxicity Assay. The levels of cytokines IFN-γ and granzyme B, which indicate the activation of NK cells, were also measured by enzyme-linked immunosorbent assay. Results: Treatment with 1,25(OH)2D3 enhanced the susceptibility of both the haematological tumour cell line Kasumi-1 and solid tumour cell line MDA-MB-231 to NK92 cells. miR-302c and miR-520c expression was induced, and their levels inversely correlated with the levels of NKG2D ligands MICA/B and ULBP2 upon 1,25(OH)2D3 treatment. A luciferase reporter assay revealed that miR-302c and miR-520c directly targeted the 3′-UTRs of MICA/B and ULBP2 and negatively regulated the expression of MIA/B and ULBP2. Moreover, upregulation of miR-302c or miR-520c by transfection of their mimics remarkably reduced the viability of Kasumi-1 cells upon NK cell co-incubation. By contrast, the suppression of the activity of miR-302c or miR-520c by their respective antisense oligonucleotides improved the resistance of Kasumi-1 cells to NK cells. Conclusion: 1,25(OH)2D3 facilitates the immuno-attack of NK cells against malignant cells partly through downregulation of miR-302c and miR-520c and hence upregulation of the NKG2D ligands MICA/B and ULBP2.

Abstract
BACKGROUND The influence of procedural arrhythmia termination on long-term single-procedure clinical outcome in patients with non-paroxysmal atrial fibrillation (AF) remains controversial. METHODS An individualized stepwise ablation strategy was used in 200 consecutive patients with non-paroxysmal AF who underwent first-time radiofrequency catheter ablation, with pulmonary vein isolation and sinus rhythm (SR) restoration as the primary endpoints. RESULTS SR was restored by ablation in 94 patients, including 32 with AF directly and 62 with intermediate atrial tachycardia (AT). Cardioversion was performed to restore SR in 106 patients, including 31 with intermediate AT, and 75 with sustained AF. During a mean follow-up of 50.0 ± 9.3 months, single-procedure success was achieved in 99 (49.5%) patients. There was a significant difference in long-term success between patients with SR restoration by ablation and by cardioversion (63.8% vs 36.8%; P < 0.001), but not between patients with AF termination by ablation and by cardioversion (53.6% vs 42.7%; P = 0.146). SR restoration by ablation (odds ratio = 3.032; 95% confidence interval = 1.703-5.398; P < 0.001) was the only predictor of single-procedure success by logistic regression analyses. In patients with intermediate AT (n = 93), AT termination by ablation was associated with a higher success rate than AT termination by cardioversion (62.9% vs 22.6%; P < 0.001). CONCLUSIONS SR restoration and AT termination by ablation were both associated with an improved long-term single-procedure clinical outcome in patients with non-paroxysmal AF.

Abstract
PURPOSE We sought to evaluate the disregarded spatial torsion of the ipsilateral superior and inferior pulmonary veins (PVs). METHODS Forty-eight consecutive atrial fibrillation patients, with four discrete PVs, were enrolled. The ostium plane of each PV, labeled by three landmarks on the CT image, was identified by three experienced observers respectively. Angle and distance between ostium planes were used to reach a consensus and to select the best ostium plane of each PV. A common ostium plane of the ipsilateral PV was computed using the two geometric centers of each side PVs and the axial center of the two geometric centers. The torsion angle was defined as the absolute difference of the two dihedral angles between the common ostium plane and the best ostium plane of the superior and inferior PVs. RESULTS The torsion angle >15° was found in 16 left PVs (16/48) and in nine right PVs (9/48, P = 0.104). Moreover, in two cases (2.1 %), the torsion angle exceeded 30° (one left PV and one right PV). The torsion angle of the left PVs was significantly greater than that of the right PVs (13.65 ± 5.90° vs. 10.61 ± 5.96°, P = 0.014). Furthermore, in 29 paroxysmal AF patients, the spatial torsion of the left side PVs was 13.70 ± 5.18°, which was significant greater than that of the right side PVs (10.69 ± 5.52°, P = 0.037). CONCLUSIONS There was a significant torsion between the ipsilateral PVs, which should be taken into account when physicians plan their ablation to avoid a single-plane circumferential ablation.

Abstract
PURPOSE OF INVESTIGATION The aim of the study was to evaluate the rate of human papillomavirus (HPV) infection clearance after loop electrosurgical excision (LEEP) procedure conization for cervical intraepithelial neoplasia (CIN) and the factors related to such clearance and to assess the relation between HPV and recurrence. MATERIALS AND METHODS A total 141 patients who underwent LEEP owing to high-risk human papillomavirus (HR-HPV) associated with CIN were involved this study. All patients with negative margins on LEEP specimens were followed up with HPV testing and cervical smear after three, six, nine, and 12 months post-treatment. If necessary, cervical biopsy under colposcopy was performed. RESULTS LEEP can effectively eliminate HPV infection. Most patients cleared HPV infection within six months. The persistent HPV infection rates were 44.6%,10.6%, 5.7%, and 2.1% after three, six, nine, and 12 months, respectively. The clearance rates were significantly slower in patients with HPV 16 infection, and not differ significantly by age, parity, and pathologic degree. Patients with persistent HR-HPV infection after treatment had a significantly higher risk for recurrence/residual after LEEP compared to patients with negative HPV infection. CONCLUSION The authors concluded that patients who were positive for HPV infection, especially for HPV 16, should be followed up closely after treatment.

Abstract
Microcapsules with good mechanical stability were prepared using an appropriate mixture of alginate and acrylic terpolymer. It was found from the microscopic observation that the microcapsules had a porous structure with interconnected pores, with a size of 50-150 nm. The results of the permeability experiment of microcapsules using FITC-dextrans showed that the capsule had a molecular mass cut-off of 120 kDa. The hepatocytes encapsulated in both alginate and acrylic terpolymer with gelatin and PVA rapidly aggregated in the core. The aggregated cells showed high albumin synthesis and ammonia removal, suggesting good metabolic function.

Abstract
AIMS This study aimed to explore if the right ventricular outflow tract (RVOT) pacing is superior to right ventricular apical (RVA) pacing on the overall left ventricular (LV) function and regional wall motion. METHODS AND RESULTS Sixty patients with atrio-ventricular (AV) block and normal ejection fraction undergoing dual-chamber pacemaker implantation were randomized to permanent ventricular stimulation either in the RVOT or the RVA. Left ventricular volume, ejection fraction, and LV regional wall motion were assessed by echocardiography. Right ventricular apical pacing had prolonged QRS duration, compared with RVOT pacing (154.1 ± 26.5 vs. 120.9 ± 22.3, P< 0.05). There were also significant differences in LV pre-ejection interval and interventricular mechanical delay (IVMD) at 12-month follow-up between the two groups, but none in the LV volume, left ventricular ejection fraction, and index of systolic synchrony (Ts-SD). During RVA pacing, the average peak systolic velocity (Sm) of 12 LV segments [3.5, 95% confidence interval (CI) 3.2-3.8 cm/s] had a trend of being lower compared with RVOT pacing (3.9, 95% CI 3.5-4.1 cm/s) (P= 0.09). Further analysis showed that the Sm at the inferior wall and posterior-septum wall was significantly decreased during RVA pacing compared with RVOT pacing. There were no significant differences for other LV segments. CONCLUSION The RVOT pacing in AV block patients over 1 year may be superior to RVA pacing in terms of regional LV performance, LV global electromechanical delay, and IVMD, although intraventricular dyssynchrony and LV volumes do not differ. Larger trials with clinical endpoints are warranted to conclusively define the advantages of RVOT or RV septal pacing.

Abstract
PURPOSE High myopia is a public health problem because of its high prevalence and is a major cause of blindness. The physiopathology of myopia remains unknown and mechanisms causing the disease are most probably complex, combining acquired environmental and genetic factors. The most recent data suggest that genetic determinisms of high myopia could be highly dependent on subject phenotype. The aim of this study was to analyse the ocular components of a high myopic population to verify whether high myopia corresponds to a homogeneous phenotype. PATIENTS AND METHODS We analysed the biometric characteristics of 718 myopic eyes with a spherical equivalent of less than -5 diopters. The biometric parameters (corneal radius, axial length, and intraocular pressure) were compared controlling for sex and the degree of myopia. RESULTS We found a difference between the phenotype of males and females. For men, axial length was the only determinant of the myopic phenotype, whereas for women, the myopic phenotype was determined by axial length and corneal radius. This difference between the phenotypes was more evident for myopia with a spherical equivalent greater than -10 diopters (moderate myopia). This difference between males and females disappeared in myopia less than -15 diopters. CONCLUSION There are intersex differences considering the high myopia phenotype at a spherical equivalent less than -5 diopters. However, this difference disappears for extremely high myopia with a spherical equivalence of less than -15 diopters.

Abstract
INTRODUCTION We investigated the second-generation tyrosine kinase inhibitors, dasatinib and nilotinib, for their potential to overcome resistance in the imatinib-resistant K562 cell line, and evaluated whether rapamycin, an mammalian target of rapamycin (mTOR) inhibitor, and bortezomib, a proteasome inhibitor, could increase imatinib sensitivity in resistant cell lines. METHODS Cell lines, including K562 (chronic myeloid leukaemia in blast crisis) and K562r (imatinib-resistant K562), were exposed to dasatinib, nilotinib, rapamycin, bortezomib, and rapamycin plus imatinib. Cell proliferation was measured by 3-[4, 5-dimethylthia-zol-2-yl]-2, 5-diphenyl tetrazolium bromide (MTT) assay and mTOR signaling pathways were assessed by Western blotting. RESULTS Dasatinib, nilotinib, and bortezomib inhibited proliferation of K562 and K562r cell lines at nm concentrations. Resistance of K562r due to duplication of autophosphorylation of wild-type Bcr-Abl was not overcome by dasatinib and nilotinib, but was sensitive to bortezomib. Rapamycin partially inhibited proliferation of K562 and K562r cell lines. Rapamycin plus imatinib did not have a more inhibitory effect on the proliferation of K562 and K562r cell lines. CONCLUSION K562r due to duplication of autophosphorylation of wild-type Bcr-Abl induced by imatinib was still partially resistant to dasatinib and nilotinib, but this was overcome by incremental dosing. Rapamycin did not enhance imatinib sensitivity. The blockade of the ubiquitin-proteasome pathway could be effective in overcoming resistance in the K562r imatinib-resistant cell line.

Abstract
(2S,3R,4R,5S,6R)-2-(3-(4-Ethoxybenzyl)-4-chlorophenyl)-6-hydroxymethyl-tetrahydro-2H-pyran-3,4,5-triol (dapagliflozin; BMS-512148) is a potent sodium-glucose cotransporter type II inhibitor in animals and humans and is currently under development for the treatment of type 2 diabetes. The preclinical characterization of dapagliflozin, to allow compound selection and prediction of pharmacological and dispositional behavior in the clinic, involved Caco-2 cell permeability studies, cytochrome P450 (P450) inhibition and induction studies, P450 reaction phenotyping, metabolite identification in hepatocytes, and pharmacokinetics in rats, dogs, and monkeys. Dapagliflozin was found to have good permeability across Caco-2 cell membranes. It was found to be a substrate for P-glycoprotein (P-gp) but not a significant P-gp inhibitor. Dapagliflozin was not found to be an inhibitor or an inducer of human P450 enzymes. The in vitro metabolic profiles of dapagliflozin after incubation with hepatocytes from mice, rats, dogs, monkeys, and humans were qualitatively similar. Rat hepatocyte incubations showed the highest turnover, and dapagliflozin was most stable in human hepatocytes. Prominent in vitro metabolic pathways observed were glucuronidation, hydroxylation, and O-deethylation. Pharmacokinetic parameters for dapagliflozin in preclinical species revealed a compound with adequate oral exposure, clearance, and elimination half-life, consistent with the potential for single daily dosing in humans. The pharmacokinetics in humans after a single dose of 50 mg of [(14)C]dapagliflozin showed good exposure, low clearance, adequate half-life, and no metabolites with significant pharmacological activity or toxicological concern.

Abstract
We report about a male patient, who underwent bilateral total adrenalectomy due to ACTH-dependent Cushing's syndrome without pituitary adenoma in his 11th year of life. Symptoms of Cushing's disease were absent during the follow-up period. Height and body weight followed the percentiles 25 and 50 respectively. An endogenous cortisol production was not detected and steroid substitution became necessary. Five years after the surgery, he showed normal cortisol levels, but there was no cortisol increase under ACTH-loading. Nine and 12 years (1993) after surgery, we found normal, physiological levels of cortisol suggestive of normal functioning adrenal glands (day profile of cortisol, Liddle-Test, ACTH-Test, CRH-Test, cortisol excretion in 24-h-urine). Moreover, baseline ACTH and its rise under CRH stimulation were normal. Scintigraphy revealed normal-sized adrenal tissue in orthotopic position on both sides. Steroid supplementation was discontinued. Presently the patient is healthy, active and under no steroid therapy. No evidence of residual or relapsing Cushing's disease or Nelson's syndrome has been found up to this point.

Abstract
To compare magnetic resonance (MR) imaging, computed tomography (CT) and radiography for the detection of arthropathies in patients with haemophilia. Forty-one symptomatic joints in 14 men with haemophilia, ages 11-24 years (mean age 17.5 +/- 3.9 years) were examined with radiography, CT and MR. Images of each joint were acquired on the same day. The precontrast MR examination obtained coronal spin-echo T1 images and gradient echo with rephasing T2* images, as well as sagittal, axial gradient echo with rephasing T2* images using a low-field-strength 0.3-T MR imager. For the postcontrast MR examination, coronal, sagittal and axial images were acquired using the same precontrast T1 sequence. Thirteen joints were also examined on enhanced MR. The severity of damage was classified using conventional radiographical staging. Severely affected haemophilic arthropathy (HA) patients (stage 5) were excluded. Findings of soft tissue swelling, osteoporosis, epiphyseal overgrowth, joint erosion, cysts, joint space narrowing, bone marrow oedema, joint effusion, haemorrhage, synovial hypertrophy and widened intercondylar notches as well as anterior and posterior cruciate ligaments (for the knee) were used in all imaging comparisons. The joints were classified by radiographical criteria into stage 0 (n = 5), stage 1 (n = 7), stage 2 (n = 6), stage 3 (n = 8) and stage 4 (n = 15). Soft tissue swelling or joint effusion was observed in 33 joints on radiographs, in 34 on both CT and MR; joint erosions were observed in 34 joints on MR, 33 on CT and 20 on radiographs. Joint cysts appeared in 21 joints on MR, 18 on CT and 9 on radiographs. Significant differences in detection of erosion and cysts were found between radiography and CT (P < 0.05) and radiography and MR imaging (P < 0.05), not between CT and MR (P > 0.05). MR was better for detecting foci of both erosion and cysts than CT and radiography, and CT was better than radiography. MR imaging, CT and radiography were equally effective in showing the changes of epiphyseal overgrowth in 26 joints, joint space narrowing in 14 joints and widened intercondylar notches in 20 knee joints. However, only MR imaging detected tears in 17 anterior and 13 posterior cruciate ligaments in the 20 knee joints with widened intercondylar notches. Bone marrow oedema in 14 joints, haemorrhage in 34 joints and synovial hypertrophy in 27 joints were seen on MR images, but not on CT or radiography. MR imaging is superior to CT and conventional radiography for detecting abnormal changes and should be considered the first choice among imaging modalities in evaluating HAs.
