Abstract
OBJECTIVE To explore the effect of 8-MOP on the blood-brain barrier in mice model of cerebral infarction and the underlying mechanism. MATERIALS AND METHODS Middle cerebral artery occlusion (MCAO) model was established to induce permanent cerebral infarction. The neurological function was observed and scored by the modified longa score method after model establishment. Besides, the water content of brain tissue was measured by the standard dry weight method. Evans blue exudation rate was used to evaluate the effect of 8-MOP on the permeability of the blood-brain barrier. Western-blot and quantitative polymerase chain reaction (qPCR) were used to detect the expression of MMP-9, claudin-5, vascular endothelial growth factor (VEGF), as well as the NFE2-related factor 2 (Nrf-2)/hemeoxygenase 1 (HO-1) pathway. RESULTS 8-MOP could reduce the neurological deficit scores in a dose-dependent manner, thereby reducing cerebral edema. After 8-MOP treatment, the expression of MMP-9 decreased in ischemic brain tissue, whereas the expression of claudin-5, VEGF, and GFAP increased, suggesting that the blood-brain barrier ultrastructure was improved. In addition, the expression of Nrf-2 and HO-1 decreased after the model establishment of cerebral infarction. However, the expression of Nrf-2 and HO-1 increased in ischemic brain tissue after 8-MOP treatment. CONCLUSIONS 8-MOP may protect the blood-brain barrier via the Nrf-2/HO-1 pathway.

Abstract
Oxygen vacancies play crucial roles in defining physical and chemical properties of materials to enhance the performances in electronics, solar cells, catalysis, sensors, and energy conversion and storage. Conventional approaches to incorporate oxygen defects mainly rely on reducing the oxygen partial pressure for the removal of product to change the equilibrium position. However, directly affecting reactants to shift the reaction toward generating oxygen vacancies is lacking and to fill this blank in synthetic methodology is very challenging. Here, a strategy is demonstrated to create oxygen vacancies through making the reaction energetically more favorable via applying interfacial strain on reactants by coating, using TiO2 (B) as a model system. Geometrical phase analysis and density functional theory simulations verify that the formation energy of oxygen vacancies is largely decreased under external strain. Benefiting from these, the obtained oxygen-deficient TiO2 (B) exhibits impressively high level of capacitive charge storage, e.g., ≈53% at 0.5 mV s-1 , far surpassing the ≈31% of the unmodified counterpart. Meanwhile, the modified electrode shows significantly enhanced rate capability delivering a capacity of 112 mAh g-1 at 20 C (≈6.7 A g-1 ), ≈30% higher than air-annealed TiO2 and comparable to vacuum-calcined TiO2 . This work heralds a new paradigm of mechanical manipulation of materials through interfacial control for rational defect engineering.

Abstract
As part of an underground gas migration study, two radioactive noble gases (37Ar and 127Xe) and two stable tracer gases (SF6 and PFDMCH) were injected into a historic nuclear explosion test chimney and allowed to migrate naturally. The purpose of this experiment was to provide a bounding case (natural transport) for the flow of radioactive noble gases following an underground nuclear explosion. To accomplish this, soil gas samples were collected from a series of boreholes and a range of depths from the shallow subsurface (3 m) to deeper levels (~160 m) over a period of eleven months. These samples have provided insights into the development and evolution of the subsurface plume and constrained the relative migration rates of the radioactive and stable gas species in the case when the driving pressure from the cavity is low. Analysis of the samples concluded that the stable tracer SF6 was consistently enriched in the subsurface samples relative to the radiotracer 127Xe, but the ratios of SF6 and 37Ar remained similar throughout the samples.

Abstract
BACKGROUND Enrofloxacin may be an alternative antimicrobial for unresponsive cases of severe bacterial infections in pregnant mares. As pregnancy may affect drug bioavailability, distribution, metabolism and excretion, dose adjustment might be necessary. OBJECTIVES To determine the disposition of orally and intravenously administered enrofloxacin in pregnant and non-pregnant mares. STUDY DESIGN Randomised cross-over experiment. METHODS Six light-breed, healthy pregnant mares (260 days gestation) were given a single dose of either intravenous (5 mg/kg bwt) or oral compounded (7.5 mg/kg bwt) enrofloxacin, with the opposite dose administered after a 7-day washout. The protocol was repeated 45-60 days post-partum, 15-30 days after foals were weaned. Plasma samples were obtained via venepuncture at 0, 5, 10, 20, 30, 45, 60, 90 min, and 2, 3, 4, 6, 8, 12, 24, 36, 48 and 72 h after enrofloxacin administration. Enrofloxacin and ciprofloxacin concentrations were measured by LC-MS/MS. Concentration versus time data were analysed based on non-compartmental pharmacokinetics. RESULTS Enrofloxacin AUC0-∞ was significantly higher in pregnant mares than non-pregnant mares after PO administration and tended to be higher after i.v. administration. Ciprofloxacin maximum plasma concentration (Cmax ) and concentration at 24 h (C24h ) were higher, and half-life of the terminal phase (t½λz ) was longer in pregnant mares than non-pregnant mares after oral administration. Similarly, ciprofloxacin C24h was higher in pregnant mares with intravenous administration. Oral bioavailability did not differ based on pregnancy status. MAIN LIMITATIONS Only six healthy light breed mares were assessed. Disease or horse breed may affect the endpoints evaluated. A lack of established enrofloxacin AUC/MIC targets for equine pathogens limits pharmacokinetic-pharmacodynamic conclusions. CONCLUSIONS The oral form of enrofloxacin was well absorbed, and oral bioavailability was comparable to previous studies. While differences in enrofloxacin and ciprofloxacin pharmacokinetics were seen between pregnant and non-pregnant mares, the recommended drug dose and dose intervals are appropriate for MIC <0.25 µg/mL. Dosages may need to be adjusted for bacteria with a MIC >0.25 µg/mL.

Abstract
Objective: To compare the clinical efficacy between endoscopic nipple-sparing mastectomy with immediat reconstruction using prosthesis implantation and open surgery. Methods: Totally 189 early-stage breast cancer patients admitted at Department of Breast and Thyroid Surgery, Southwest Hospital, Third Military Medical University from January 2013 to December 2017 were enrolled. Among them, 104 patients underwent endoscopic nipple sparing mastectomy with immediat reconstruction using prosthesis implantation (endoscopic group), with an age of (41.7±6.1) years (range: 25 to 51 years), and 85 patients underwent traditional open surgery (open group), with an age of (41.6±7.7) years (range: 27 to 67 years). The operative duration, the volume of intraoperative blood loss, the volume of drainage in 3 days after surgery, postoperative complications and patients' satisfaction of breast reconstruction were compared between the two groups using t test, Mann-Whitney U test, χ(2) test or non-parametric test. Results: There were no statistically significant differences in postoperative complications, the rates of recurrence and overall survival between the two groups (P>0.05). The operative duration (sentinel lymph node biopsy: (178± 80) minutes vs. (198±42) minutes, t=-2.082, P=0.039; axillary lymph node dissection: (204±79) minutes vs. (233±49) minutes, t=-2.952, P=0.004), the volume of drainage in three days postoperative ((183±141)ml vs. (237±104) ml, t=- 2.938, P=0.004) in the open group were lower than endoscopic group. The volume of intraoperative blood loss in the endoscopic group was lower than that in the open group ((87±64) ml vs. (62± 36) ml, t=3.210, P=0.002). Patients' satisfaction of breast reconstruction in the endoscopic group was higher than that in the open group. Conclusions: Both endoscopic nipple sparing mastectomy with immediat reconstruction using prosthesis implantation and open surgery are safe in oncology. Endoscopic surgery maybe more suitable alternative in breast reconstruction for early-stage breast cancer patients.

Abstract
The MORDOR I trial1, conducted in Niger, Malawi and Tanzania, demonstrated that mass azithromycin distribution to preschool children reduced childhood mortality1. However, the large but simple trial design precluded determination of the mechanisms involved. Here we examined the gut microbiome of preschool children from 30 Nigerien communities randomized to either biannual azithromycin or placebo. Gut microbiome γ-diversity was not significantly altered (P = 0.08), but the relative abundances of two Campylobacter species, along with another 33 gut bacteria, were significantly reduced in children treated with azithromycin at the 24-month follow-up. Metagenomic analysis revealed functional differences in gut bacteria between treatment groups. Resistome analysis showed an increase in macrolide resistance gene expression in gut microbiota in communities treated with azithromycin (P = 0.004). These results suggest that prolonged mass azithromycin distribution to reduce childhood mortality reduces certain gut bacteria, including known pathogens, while selecting for antibiotic resistance.

Abstract
Crystal phase engineering is a promising strategy to tune the catalytic performance of metal nanomaterials. Generally, the crystal phase effect on catalysis is ascribed to distinct surface atomic arrangements of catalysts with different crystal phases. Here we show that even for similar surfaces, such as the close-packed surfaces, different crystal phases have considerably different surface reactivities due to their distinct intrinsic surface strains. Using first-principles calculations, we find that the close-packed surfaces of hexagonal close-packed (HCP) and double HCP (4H) gold have significantly smaller intrinsic strains (∼1.3%) than those of face-centered cubic (FCC) gold (∼2.3%). These distinct intrinsic surface strains result in various oxygen adsorption energies and O2 dissociation barriers on these close-packed gold surfaces, and the dissociation of O2 on different crystal phases and surfaces follows the Brønsted-Evans-Polanyi principle.

Abstract
Heterostructures with abundant phase boundaries are compelling for surface-mediated electrochemical applications. However, rational design of such bifunctional electrocatalysts for efficient hydrogen and oxygen evolution reactions (HER and OER) is still challenging. Here, due to the well-matched lattice parameters, we easily achieved the epitaxy of two-dimensional ternary nickel thiophosphate (NiPS3) nanosheets with in-grown dinickel phosphide (Ni2P) through an in situ growth strategy. Density functional theory calculations reveal that the NiPS3/Ni2P heterojunction significantly decreases the kinetic barrier for hydrogen adsorption and accelerates electron transfer due to the built-in electric field at the epitaxial interfaces. The significantly improved electrocatalytic performance is shown to be closely related to the epitaxial interfacial area rather than the amount of secondary phase. Notably, the resultant NiPS3/Ni2P heterostructures enable an overall water splitting electrolyzer to achieve 50 mA cm-2 at a lower bias of 1.65 V compared to that for the pristine NiPS3 alone (2.02 V) and even the benchmark Pt/C//IrO2 electrocatalysts (1.69 V).

Abstract
BACKGROUND Vitiligo is a common depigmentation disorder resulting from destruction of melanocytes, and has both genetic and environmental influences. Although genomic analyses have been performed to investigate the pathogenesis of vitiligo, the lipidomics, metabolomics and proteomics of serum have not been reported, and the role of small molecules and serum proteins in vitiligo remains unknown. AIM To study the metabolite and protein profiles in patients with vitiligo and healthy controls (HCs). METHODS Plasma samples from 60 participants (29 patients with vitiligo and 31 HCs) were analysed. Untargeted lipidomics, metabolomics and isobaric tags for relative and absolute quantification-based proteomics were performed using high performance liquid chromatography-tandem mass spectrometry. In addition, to validate differentially expressed metabolites in patients with vitiligo, plasma enzyme-linked immunosorbent assay was performed. RESULTS We identified differential expression of several metabolites and proteins involved in the immune system. Among these metabolites and proteins, lysophosphatidylcholine, platelet-activating factor, sn-glycerol-3-phosphocholine, succinic acid, CXCL4 and CXCL7 were significantly elevated in the plasma of patients with vitiligo, while aspartate was downregulated. CONCLUSION Our study has characterized several serum metabolites and proteins that could be potential candidate biomarkers in vitiligo, and provides a comprehensive insight into the role of immune system and aspartate metabolism in vitiligo.

Abstract
Evaporation is a recognized contributor to tear film thinning and tear breakup (TBU). Recently, a different type of TBU is observed, where TBU happens under or around a thick area of lipid within a second after a blink. The thick lipid corresponds to a glob. Evaporation alone is too slow to offer a complete explanation of this breakup. It has been argued that the major reason of this rapid tear film thinning is divergent flow driven by a lower surface tension of the glob (via the Marangoni effect). We examine the glob-driven TBU hypothesis in a 1D streak model and axisymmetric spot model. In the model, the streak or spot glob has a localized high surfactant concentration, which is assumed to lower the tear/air surface tension and also to have a fixed size. Both streak and spot models show that the Marangoni effect can lead to strong tangential flow away from the glob and may cause TBU. The models predict that smaller globs or thinner films will decrease TBU time (TBUT). TBU is located underneath small globs, but may occur outside larger globs. In addition to tangential flow, evaporation can also contribute to TBU. This study provides insights about mechanism of rapid thinning and TBU which occurs very rapidly after a blink and how the properties of the globs affect the TBUT.

Abstract
Understanding the chemistry in the gelation (interfacial assembly) of graphene oxide (GO) is very essential for the practical uses of graphene-based materials. Herein, with the designed artificial interfaces due to the introduction of water-miscible isopropanol, the gelation of GO is achieved in water at an ultralow concentration (0.1 mg mL-1 , the lowest ever-reported) with a solvothermal treatment. Intrinsically, with a lower intercalation energy, water shows much stronger attraction with GO than isopropanol, inducing a microphase separation in the miscible mixture of isopropanol and water. In the solvothermal process, the partially reduced GO sheets interact with each other along the water-isopropanol interface and assemble into interconnected frameworks. In general, the formation of the artificial interface results in locally concentrated GO in the water phase, which is the final driving force for the gelation at ultralow concentration. Thus, the threshold for the GO gelation concentration is dependent upon the water fraction in the mixture and water acts as the spacer to facilitate the gelation and final control of the resulting materials microstructure. This study enriches interface/gelation chemistry of GO and indicates a practical way for precise structural control and scale-up preparation of graphene-based materials.

Abstract
BACKGROUND In selective cases, enrofloxacin may be an alternative antibacterial agent to treat unresponsive infections in pregnant mares. Supratherapeutic doses of enrofloxacin are toxic to adult horses and also to newborn foals, however, it is unknown if enrofloxacin crosses the equine placenta or if it is toxic to the fetus. OBJECTIVES To assess the diffusion of enrofloxacin and its metabolite to fetal fluids and its effects on fetal cartilage when administered to pregnant mares. STUDY DESIGN In vivo and terminal controlled experiment. METHODS Healthy mares at 260 days of gestation were allocated into three groups: untreated (n = 3), therapeutic treatment (5 mg/kg enrofloxacin, i.v., n = 7) or supratherapeutic treatment (10 mg/kg, i.v., n = 6) for 11 days. Fetal fluids were collected on days 1, 5 and 11 of treatment. Premature delivery was induced on day 11 with oxytocin and fetal fluids and plasma were collected during delivery. Plasma and fetal fluid enrofloxacin and ciprofloxacin concentrations were measured by liquid chromatography-mass spectrometry. Fetal articular cartilage was examined macroscopically and histologically for lesions. RESULTS Enrofloxacin and ciprofloxacin reached the minimum inhibitory concentrations for common pathogens in all fluids. Ciprofloxacin did not increase with the double enrofloxacin dose in maternal plasma, but allantoic fluid showed a 10-fold increase relative to fetal trough plasma concentrations. Administration of enrofloxacin at recommended doses did not result in cartilaginous lesions in fetuses. MAIN LIMITATIONS Only one time point in gestation was evaluated and mares treated in the study were healthy at the time of treatment. It remains to be determined if enrofloxacin shows toxicity at other stages of pregnancy, after a longer duration of treatment, or once the foals are delivered and articular surfaces are weightbearing. CONCLUSIONS Short-term administration of enrofloxacin to late gestation mares resulted in detectable enrofloxacin and ciprofloxacin concentrations in fetal fluids and did not result in macroscopic or microscopic lesions in the fetus. While further research is needed to address long-term foal outcomes, enrofloxacin may be useful for select bacterial infections in pregnant mares.

Abstract
BACKGROUND Atherosclerosis is a chronic inflammatory disease. Accumulating evidence suggests that long non-coding RNAs (lncRNAs) and microRNAs have emerged as critical regulators of atherosclerosis; however, whether they have crosstalk on this issue remains elusive. Here, we investigated the potential associations between lncRNA-MALAT1 and miR-155 on the regulation of atherosclerosis. METHODS Quantitative real-time PCR was employed to assess the expression of MALAT1, IL-6 and IL-8. ELISA was performed to measure the secretion of IL-6 and IL-8. MTT assay was used to determine the proliferation of Human Coronary Artery Endothelial Cells (HCAECs). Flow cytometry was used to measure the cell apoptosis. Western blot was used to assess the expression of apoptosis-related proteins and the phosphorylation of STAT1 and STAT3. RESULTS We found that the pro-inflammatory cytokine release and the apoptosis of HCAECs were elevated upon ox-LDL treatment, while MALAT1 expression was also up regulated. Knocking down of MALAT1 boosted ox-LDL-induced cytokine release and apoptosis of HCAECs. The binding site of miR-155 in MALAT1 sequence was confirmed by dual luciferase assay. Furthermore, miR-155 inhibition significantly repressed ox-LDL mediated inflammation and apoptosis of HCAECs via SOCS1. At last, we found that MALAT1 could suppress the inflammatory cytokine release and cell apoptosis via sponging miR-155 to increase SOCS1 level, which in turn restrained JAK-STAT pathway. CONCLUSION In summary, this study revealed the mechanisms by which MALAT1 worked as a putative atherosclerosis suppressor via miR-155 and SOCS1. Therefore, modulation of MALAT1/miR-155/SOCS1 axis might alleviate the inflammation persisted in atherosclerosis.

Abstract
A previous mathematical model has successfully simulated the rapid tear thinning caused by glob (thicker lipid) in the lipid layer. It captured a fast spreading of polar lipid and a corresponding strong tangential flow in the aqueous layer. With the simulated strong tangential flow, we now extend the model by adding equations for conservation of solutes, for osmolarity and fluorescein, in order to study their dynamics. We then compare our computed results for the resulting intensity distribution with fluorescence experiments on the tear film. We conclude that in rapid thinning, the fluorescent intensity can linearly approximate the tear film thickness well, when the initial fluorescein concentration is small. Thus, a dilute fluorescein is recommended for visualizing the rapid tear thinning during fluorescent imaging.

Abstract
OBJECTIVE To explore the involvement of the wingless-type MMTV integration site (WNT) and bone morphogenetic protein (BMP) antagonists dickkopf-related protein 1 (DKK1), frizzled-related protein (FRZB) and gremlin 1 (GREM1) in knee injury and osteoarthritis (OA). DESIGN The antagonists were immunoassayed in synovial fluid from a cross-sectional cohort of nine knee healthy reference subjects, patients with recent (0-77 days, n = 158) or old (1-37 years, n = 50) knee injuries, and OA (n = 22). Cartilage (ARGS-aggrecan, cartilage oligomeric matrix protein and C2C type II collagen) and other biomarkers were assessed in synovial fluid in a subset of samples. Statistical analysis was by Kendall's tau (τ) correlation, Mann-Whitney U test, and linear regression analysis. RESULTS Compared to references, median concentration of GREM1 (but not DKK1 and FRZB) was elevated 1.5-fold immediately after injury, and FRZB was reduced 1000-folds in OA. All three antagonists decreased with increasing time after injury as well as with increasing age, but the temporal change after injury was less accentuated for FRZB (peaked 8-22 days after injury) compared to that of DKK1 and GREM1 (peaked immediately after injury). In the recent injury group, there was a correlation between GREM1 and DKK1 (τ = 0.172); FRZB concentrations correlated with concentrations of cartilage biomarkers (τ between 0.257 and 0.369), while DKK1 and GREM1 were inversely correlated (τ between -0.177 and -0.217) with these markers. CONCLUSIONS Our results indicate separate roles for the antagonists, where DKK1 and GREM1 had similarities in response to injury and in OA, with a different response for FRZB.

Abstract
Chitosan/montmorillonite intercalated composite (CTS/MMT) was used as an effective adsorbent for removal of reactive dyes, i.e. Reactive Black 5 (RB5), Reactive Red 136 (RR136), Reactive Yellow 145 (RY145) and Reactive Blue 222 (RB222). Taguchi method attached grey relational analysis was applied to determine the optimal adsorption conditions, including pH, initial concentration of dye, temperature, adsorbent dosage and contact time, for achieving simultaneous maximization of removal percentage and adsorption capacity. The percentage contribution of each adsorption condition was determined in the analysis of variance and showed that the most effective parameter in removal of RB5, RY145 and RB222 is the dye solution pH, whereas the initial concentration was the determining factor for optimum efficiency for the dye RR136. Under respective optimal condition, the removal percentages and adsorption capacity of four reactive dyes onto CTS/MMT were both found in the following order: RR136 > RY145 > RB5 > RB222. The maximum removal percentages of 78.8 and 49.5%, and the adsorption capacity of 315.20 and 123.75 mg/g were obtained for RR136 and RB222, respectively. The adsorption behaviors showed that the adsorption kinetics and isotherms were in best agreement with Avrami fractionary order model and the Toth isotherm, respectively.

Abstract
Background No standardized measures specifically assess cancer survivors' and healthcare providers' experience of Survivor Care Plans (scps). We sought to develop two care plan evaluation (cpe) measures, one for survivors (cpe-s) and one for healthcare providers (cpe-p), examine initial psychometric qualities in Alberta, and assess generalizability in Manitoba, Canada. Methods We developed the initial measures using convenience samples of breast (n = 35) and head and neck (n = 18) survivors who received scps at the end of active cancer-centre treatment. After assessing Alberta's scp concordance with Institute of Medicine (iom) recommendations using a published coding scheme, we examined psychometric qualities for the cpe-s and cpe-p. We examined generalizability in Manitoba, Canada, with colorectal survivors discharged to primary care providers for follow-up (n = 75). Results We demonstrated acceptable internal consistency for the cpe-s and cpe-p subscales and total score after eliminating one item per subscale for cpe-s, two for cpe-p, resulting in revised scales with four 7-item and 6-item subscales, respectively. Subscale scores correlated highly indicating that for each measure the total score may be the most reliable and valid. We provide initial cpe-s discriminant, convergent, and predictive validity using the total score. Using the Manitoba sample, initial psychometrics similarly indicated good generalizability across differences in tumour groups, scp, and location. Conclusions We recommend the revised cpe-s and cpe-p for further use and development. Studies documenting the creation and standardization of scp evaluations are few, and we recommend further development of patient experience measures to improve both clinical practice and the specificity of research questions.

Abstract
Patients with osteoporotic fractures have an increased risk for secondary fractures. However, a rigorous study that assesses the effectiveness of individual osteoporotic drugs in preventing subsequent fractures is lacking. The purpose of this review was to analyze the effectiveness of anti-osteoporotic drugs in preventing secondary fractures. We searched for randomized controlled trials that showed the incidence of secondary fractures while using anti-osteoporotic drugs (bisphosphonates, selective estrogen receptor modulators, parathyroid hormone (PTH), or calcitonin) in MEDLINE, Embase.com , and Cochrane Central Register databases. We estimated risk ratios (RR) and numbers needed to treat (NNT) to prevent secondary fractures. Twenty-six studies met our eligibility criteria. There was a significant reduction in RR (0.38-0.77) after the use of anti-osteoporotic drugs for secondary vertebral fractures. Bisphosphonates and PTH significantly reduced the risk of a secondary non-vertebral fracture (RR 0.59 and 0.64). PTH needed the fewest number of patients to be treated to prevent a secondary vertebral fracture (NNT: 56). Our study demonstrated the effectiveness of anti-osteoporotic agents included in our systematic review in preventing secondary vertebral fractures. Bisphosphonates and PTH were most effective in preventing non-vertebral fractures. We suggest that clinicians should prescribe these drugs to prevent secondary vertebral/non-vertebral fractures.

Abstract
Objective: The myocardial bridging (MB) prevalence, anatomic characteristics of MB, and the relationship between characteristics of MB in mural coronary artery segment and coronary atherosclerosis were analyzed. Methods: In this perspective nonrandomized controlled study, a total of 1 132 patients who admitted to our hospital for suspected or known coronary artery disease from January 2012 to June 2013 were enrolled. All patients underwent dual-source 64-slice spiral CT coronary angiography. The general patient characteristics including gender, age, history of hypertension, diabetes, hyperlipidemia and smoking, serum level of total cholesterol (TC) and LDL-C were recorded. The length, depth and the degree of compression of myocardial bridge in systolic or diastolic phase were also analyzed in patients with MB. The relationship between MB and coronary atherosclerosis, the characteristics of MB and coronary atherosclerosis were analyzed by Spearman correlation analysis, univariate logistic regression analysis, variate logistic regression analysis and linear regression analysis. Results: Myocardial bridging was detected in 330 out of 1 132 patients, and MB was mostly located in the mural coronary artery (329/330) and at the mid-distal segment of the left anterior descending artery (LAD). Average MB length was 20.1 mm (3.3-95.5 mm) and the average depth was 2.13 mm (0.24-12.40 mm). There were 140 patients with intramyocardial MB (42.6%) and 189 patients with superficial MB (57.4%). Myocardial bridging was an independent protective factor of coronary atherosclerosis (OR=0.361, P=0.000) and the proximal segment of MB was more susceptible to atherosclerosis compared to the distal segment of MB (P=0.000). Multivariate analysis revealed that age, hypertension and the degree of compression of myocardial bridge in diastolic phase were independent factors related to the atherosclerosis (odds ratio: 1.064, 2.186 and 1.049 respectively, P value: 0.000, 0.002 and 0.000). The depth of MB was significantly correlated with systolic or diastolic narrowing(OR: 4.227, 3.398 and P value: 0.000, 0.001). Conclusions: The prevalence of myocardial bridging is 29% in this patient cohort. The proximal segment of myocardial bridging in mural coronary artery is more susceptible to atherosclerosis. In addition, the depth of myocardial bridging and the degree of compression of myocardial bridge in diastolic phase are the independent factors related to atherosclerosis.

Abstract
In this work, we proposed to demonstrate the entire 3D coronary tree using panoramic maximum intensity projection (MIP) of coronary arteries, and to detect and quantify coronary stenosis from computed tomography coronary angiography (CTCA). The performance of the proposed method was assessed in comparison with invasive coronary angiography (ICA) as reference standard. Six anonymized CTCA datasets were tested. MIP method achieved a sensitivity of 82% and a specificity of 95% for the stenosis detection with a good reproducibility (i.e. Cohen's kappa coefficient of 0.74 for the intra-rater agreement, and 0.45 for the inter-raters agreement). In stenosis quantification, three image options are provided. The original density images resulted in an accuracy of 0.85. The edge map images resulted in an accuracy of 0.79. The image combination had a better accuracy of 0.89 than any single image option. In conclusion, the panoramic MIP provided fast and accurate way for the stenosis detection and quantification. It may be helpful to assist the radiologist in identifying the location of the greatest narrowing in clinical practice.

Abstract
Objective: To evaluate the impact of various anticoagulation antiplatelet therapy strategies on the prognosis of patients with coronary heart disease combining with atrial fibrillation. Methods: Present meta analysis was performed according to search results on English EMBASE database by computer retrieval, Pubmed, the Cochrane Central Register of Controlled Trials, Medline, Chinese CBM database, CNKI database, Wan Fang database, China science and technology papers online electronic databases, manual retrieval for important international conference proceedings up to April 30 2016. Trials published in English and Chinese language, which met the Cochrane system evaluation requirements were included and the inclusion and exclusion criteria were made based on Cochrane system evaluation requirements. The end point is the incident of major adverse cardiac events (MACE), ischemic stroke and major bleeding events. The patients were randomly assigned into triple antithrombotic therapy (aspirin+ clopidogrel+ warfarin) group and dual antiplatelet therapy (aspirin+ clopidogrel) group.The collected full-text literatures underwent further quality assessment of the risks of bias using RevMan 5.3 software. Impact of various antithrombotic therapeutic strategies on the outcome of coronary heart disease patients combining with atrial fibrillation were evaluated. Results: In this meta analysis, 12 randomized controlled trials with 11 353 patients were included. Among these patients, 3 486 patients received triple antithrombotic therapy and 7 867 patients received dual anti-platelet therapy. There was no significant difference in incidence rate of MACE (OR=0.93, 95%CI 0.74-1.18, P>0.05) and the incidence rate of ischemic stroke (OR=0.88, 95%CI 0.70-1.10, P=0.27) between the two patients groups. However, the incidence rate of major bleeding events in triple antithrombotic therapy group was twice higher than that in dual anti-platelet therapy (OR=1.94, 95%CI 1.33-2.82, P=0.000 6). Conclusion: Compared with dual anti-platelet therapy strategy, coronary heart disease patients combining with atrial fibrillation who were treated by triple antithrombotic therapy strategy have the similar outcome on risk of ischemic stroke, but higher risk of major bleeding events.

Abstract
We report on the first results from a new microwave cavity search for dark matter axions with masses above 20 μeV. We exclude axion models with two-photon coupling g_{aγγ}≳2×10^{-14} GeV^{-1} over the range 23.55<m_{a}<24.0 μeV. These results represent two important achievements. First, we have reached cosmologically relevant sensitivity an order of magnitude higher in mass than any existing limits. Second, by incorporating a dilution refrigerator and Josephson parametric amplifier, we have demonstrated total noise approaching the standard quantum limit for the first time in an axion search.

Abstract
Objective: To investigate the epidemiological features of abnormal urinary fluoride rates in population with occupational exposure, and its relationships with age, work years and gender in Shanghai. Methods: A questionnaire survey was conducted respectively in 4 999 exposed workers and 283 non-exposed people during 2012-2015. Their urine samples were collected in plastic bottles and the fluoride ion selective electrode method was used for urinary fluoride level analysis. Logistic regression model was used to estimate associations between the abnormal rates and demographic/socioeconomic status of the study subjects. Results: In the past 4 years, the abnormal urinary fluoride rates (≥1.6 mg/L) in the population with occupational exposure was about 14.38%, it was about 1.43% in the control groups without occupational exposure. Their geometric mean of urinary fluoride content was 0.95 mg/L and 0.46 mg/L, respectively. The incidences of the abnormal rates in those aged ≥50 years and 34-39 years were 19.15% and 22.39%, respectively. The abnormal rate in males was 16.87%, much higher than that in females (6.85%). The abnormal rate had an upward trend along with the increased work years, especially in those with work years of ≥20 years. The abnormal rate was 23.28% in those with work years of ≥20 years and 13.29% in those with work years of <4 years. The relative risk for abnormal urinary fluoride rates was higher in male group, older age group and longer work year group, the odds ratio was 2.28, 1.10 and 1.13, respectively. Conclusions: Serious challenges exist in occupational health supervision. The relevant national standards should be updated as soon as possible. Males, those aged >50 years, and those with longer work years are the risk groups for intervention measures. More efforts are needed, such as strengthening the innovative application of health examination data and the equalization of basic public health service with comprehensive occupational health supervision programs among off-farm workers in the new medical reform.

Model-Independent Evidence for J/ψp Contributions to Λ_{b}^{0}→J/ψpK^{-} Decays. PHYSICAL REVIEW LETTERS 2016; 117:082002.

Abstract
The data sample of Λ_{b}^{0}→J/ψpK^{-} decays acquired with the LHCb detector from 7 and 8 TeV pp collisions, corresponding to an integrated luminosity of 3 fb^{-1}, is inspected for the presence of J/ψp or J/ψK^{-} contributions with minimal assumptions about K^{-}p contributions. It is demonstrated at more than nine standard deviations that Λ_{b}^{0}→J/ψpK^{-} decays cannot be described with K^{-}p contributions alone, and that J/ψp contributions play a dominant role in this incompatibility. These model-independent results support the previously obtained model-dependent evidence for P_{c}^{+}→J/ψp charmonium-pentaquark states in the same data sample.

Abstract
The oscillation frequency, [Formula: see text], of [Formula: see text] mesons is measured using semileptonic decays with a [Formula: see text] or [Formula: see text] meson in the final state. The data sample corresponds to 3.0[Formula: see text] of pp collisions, collected by the LHCb experiment at centre-of-mass energies [Formula: see text] = 7 and 8[Formula: see text]. A combination of the two decay modes gives [Formula: see text], where the first uncertainty is statistical and the second is systematic. This is the most precise single measurement of this parameter. It is consistent with the current world average and has similar precision.

Abstract
Displacement of propagating quantum states of light is a fundamental operation for quantum communication. It enables fundamental studies on macroscopic quantum coherence and plays an important role in quantum teleportation protocols with continuous variables. In our experiments, we have successfully implemented this operation for propagating squeezed microwave states. We demonstrate that, even for strong displacement amplitudes, there is no degradation of the squeezing level in the reconstructed quantum states. Furthermore, we confirm that path entanglement generated by using displaced squeezed states remains constant over a wide range of the displacement power.

Abstract
Krüppel-like factor 2 (KLF2), a novel tumor-suppressor gene, is implicated in diverse cellular processes, including cell growth, apoptosis, and invasion. However, the role and action mechanisms of KLF2 in gastric cancer (GC) need be further elucidated. The expression of KLF2 was investigated by immunohistochemical assay in human GC tissues, and lentivirus-mediated KLF2 overexpression was transfected into GC cells (AGS and HGC-27) for assessing cell proliferation and invasion, respectively indicated by MTT and Transwell assays. Subcutaneous GC tumor models were constructed for estimating tumor growth in vivo. As a result, the expression level of KLF2 was decreased in GC tissues compared with the para-carcinoma tissues (31.03% vs 53.45%, P=0.035), and negatively correlated with the lymph node metastasis in GC patients (P=0.02). Moreover, overexpression of KLF2 inhibited the cell proliferation and invasive potential and downregulated the protein expression of PCNA, Bcl-2 and MMP-9 in GC cells. The result in vivo showed KLF2 overexpression reduced the xenograft tumor growth. In conclusion, our findings indicate that KLF2 may function as a tumor suppressor involved in the progression of human GC.

Abstract
PURPOSE Analog development of existing drugs and direct drug delivery to the lungs by inhalation as treatments for multiple and extensively drug resistant (MDR and XDR) tuberculosis (TB) represent new therapeutic strategies. Pyrazinamide (PZA) is critical to drug sensitive TB therapy and is included in regimens for MDR TB. However, PZA-resistant Mycobacterium tuberculosis (Mtb) strains threaten its use. Pyrazinoic acid esters (PAEs) are PZA analogs effective against Mtb in vitro, including against the most common PZA resistant strains. However, PAEs require testing for TB efficacy in animal models. METHODS PAEs were delivered daily as aqueous dispersions from a vibrating mesh nebulizer to Mtb infected guinea pigs for 4 weeks in a regimen including orally administered first-line TB drugs. RESULTS PAEs tested as a supplement to oral therapy significantly reduced the organ bacterial burden in comparison to infected, untreated control animals. Thus, PAE aerosol therapy is a potentially significant addition to the regimen for PZA resistant MDR-TB and XDR-TB treatment. Interestingly, low dose oral PZA treatment combined with standard therapy also reduced bacterial burden. This observation may be important for PZA susceptible disease treatment. CONCLUSION The present study justifies further evaluation of PZA analogs and their lung delivery to treat TB.

Abstract
Charm meson oscillations are observed in a time-dependent analysis of the ratio of D^{0}→K^{+}π^{-}π^{+}π^{-} to D^{0}→K^{-}π^{+}π^{-}π^{+} decay rates, using data corresponding to an integrated luminosity of 3.0 fb^{-1} recorded by the LHCb experiment. The measurements presented are sensitive to the phase-space averaged ratio of doubly Cabibbo-suppressed to Cabibbo-favored amplitudes r_{D}^{K3π} and the product of the coherence factor R_{D}^{K3π} and a charm mixing parameter y_{K3π}^{'}. The constraints measured are r_{D}^{K3π}=(5.67±0.12)×10^{-2}, which is the most precise determination to date, and R_{D}^{K3π}y_{K3π}^{'}=(0.3±1.8)×10^{-3}, which provides useful input for determinations of the CP-violating phase γ in B^{±}→DK^{±}, D→K^{∓}π^{±}π^{∓}π^{±} decays. The analysis also gives the most precise measurement of the D^{0}→K^{+}π^{-}π^{+}π^{-} branching fraction, and the first observation of D^{0}-D[over ¯]^{0} oscillations in this decay mode, with a significance of 8.2 standard deviations.

Abstract
Violations of CPT symmetry and Lorentz invariance are searched for by studying interference effects in B^{0} mixing and in B_{s}^{0} mixing. Samples of B^{0}→J/ψK_{S}^{0} and B_{s}^{0}→J/ψK^{+}K^{-} decays are recorded by the LHCb detector in proton-proton collisions at center-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb^{-1}. No periodic variations of the particle-antiparticle mass differences are found, consistent with Lorentz invariance and CPT symmetry. Results are expressed in terms of the standard model extension parameter Δa_{μ} with precisions of O(10^{-15}) and O(10^{-14}) GeV for the B^{0} and B_{s}^{0} systems, respectively. With no assumption on Lorentz (non)invariance, the CPT-violating parameter z in the B_{s}^{0} system is measured for the first time and found to be Re(z)=-0.022±0.033±0.005 and Im(z)=0.004±0.011±0.002, where the first uncertainties are statistical and the second systematic.

Characterisation of the gastrointestinal mucosa-associated microbiota: a novel technique to prevent cross-contamination during endoscopic procedures. Aliment Pharmacol Ther 2016; 43:1186-96. [PMID: 27086880 DOI: 10.1111/apt.13622] [Citation(s) in RCA: 43] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2016] [Revised: 03/09/2016] [Accepted: 03/22/2016] [Indexed: 12/13/2022]
Abstract
BACKGROUND The mucosa-associated microbiota appears to be highly relevant to host-microbe interactions in the gastrointestinal (GI) tract. Thus, precise characterisation of the mucosa-associated microbiota may provide important insights for diagnostic and therapeutic development. However, for technical reasons, mucosal biopsies taken during standard endoscopic procedures are potentially contaminated by GI luminal contents. AIM To develop and validate a biopsy device that minimises contamination during sampling of the mucosa-associated microbiota. METHODS A new, encased biopsy forceps was developed, the Brisbane Aseptic Biopsy Device (BABD). This comprises sterile forceps encased by a sheath with a plug at the tip, allowing targeted, aseptic sampling of the mucosa. Matched duodenal biopsies were obtained using the BABD, standard biopsy forceps, and a sterile brush, from patients undergoing upper GI endoscopy for iron deficiency (n = 6). Total genomic deoxyribonucleic acid (gDNA) was extracted from samples and bacterial 16S rRNA gene libraries sequenced to investigate the mucosa-associated microbiota. RESULTS Microbial DNA was recovered from biopsies obtained by the BABD, confirming the presence of a duodenal mucosa-associated microbiota. This microbiota was dominated by the genus Streptococcus, with lower levels of Prevotella, Veillonella and Neisseria. At the individual patient level, substantial differences were observed between matched samples obtained using the different devices. A greater degree of bacterial diversity was observed in samples collected using the standard forceps, indicating the BABD affords collection of samples more representative of the mucosa-associated microbiota, by precluding luminal cross-contamination. CONCLUSIONS Cross-contamination can occur when mucosal biopsies are taken during standard endoscopic procedures. Utilising the novel Brisbane Aseptic Biopsy Device can reduce cross-contamination, and it offers improved opportunities to more precisely examine host-mucosa-associated microbiota interactions.

Abstract
A search for CP violation in D^{0}→K^{-}K^{+} and D^{0}→π^{-}π^{+} decays is performed using pp collision data, corresponding to an integrated luminosity of 3 fb^{-1}, collected using the LHCb detector at center-of-mass energies of 7 and 8 TeV. The flavor of the charm meson is inferred from the charge of the pion in D^{*+}→D^{0}π^{+} and D^{*-}→D[over ¯]^{0}π^{-} decays. The difference between the CP asymmetries in D^{0}→K^{-}K^{+} and D^{0}→π^{-}π^{+} decays, ΔA_{CP}≡A_{CP}(K^{-}K^{+})-A_{CP}(π^{-}π^{+}), is measured to be [-0.10±0.08(stat)±0.03(syst)]%. This is the most precise measurement of a time-integrated CP asymmetry in the charm sector from a single experiment.

Abstract
The aim of the study was to investigate the grass carp hemorrhagic infection pathway and its key-related genes. Grass carp reovirus (GCRV) might cause hemorrhagic disease in grass carps. Healthy grass carp fingerlings (N = 60) were divided into control and infected groups. Fish in the control group were intraperitoneally (ip) injected with 0.6% fish physiological saline; the infected group received 5,000,000 50% tissue culture infective doses of GCRV 873 standard strain, a double-stranded RNA (dsRNA) virus strain, ip, in 0.5 mL. Illumina HiSeqTM 2000 was used for transcriptome sequencing, and real-time polymerase chain reaction (PCR) used to detect complement factors II (C2), III (C3), and V (C5); profibrinolysin (PLG); and coagulation factor II (F2) expression. A total of 2,722,223 reads were detected in the control group, and 2,751,111 in the infected group. Among 11,023 unigenes obtained after transcriptome assembly, 10,021 unigenes were significantly differentially expressed. Gene ontology and KEGG analysis, a collection of databases dealing with genomes and biological pathways, were performed to classify unigenes into functional categories, to understand gene function and identify regulatory pathways. Real-time PCR analysis showed that C2, C3, C5, PLG, and F2 expression levels were down-regulated, confirming results of pathway-enrichment analysis. This is the first application of high-throughput sequencing technology to investigate the in vivo effects of GCRV, on genes and pathways involved in the immune response to infection in grass carp.

Abstract
The first observation of the B_{s}^{0}→D[over ¯]^{0}K_{S}^{0} decay mode and evidence for the B_{s}^{0}→D[over ¯]^{*0}K_{S}^{0} decay mode are reported. The data sample corresponds to an integrated luminosity of 3.0 fb^{-1} collected in pp collisions by LHCb at center-of-mass energies of 7 and 8 TeV. The branching fractions are measured to be B(B_{s}^{0}→D[over ¯]^{0}K[over ¯]^{0})=[4.3±0.5(stat)±0.3(syst)±0.3(frag)±0.6(norm)]×10^{-4},B(B_{s}^{0}→D[over ¯]^{*0}K[over ¯]^{0})=[2.8±1.0(stat)±0.3(syst)±0.2(frag)±0.4(norm)]×10^{-4},where the uncertainties are due to contributions coming from statistical precision, systematic effects, and the precision of two external inputs, the ratio f_{s}/f_{d} and the branching fraction of B^{0}→D[over ¯]^{0}K_{S}^{0}, which is used as a calibration channel.
