Abstract
The spin Hall effect (SHE) is the conversion of charge current to spin current, and nonmagnetic metals with large SHEs are extremely sought after for spintronic applications, but their rarity has stifled widespread use. Here, we predict and explain the large intrinsic SHE in β-W and the A15 family of superconductors: W3Ta, Ta3Sb, and Cr3Ir having spin Hall conductivities (SHCs) of -2250, -1400, and 1210ℏ e ( S / cm ) , respectively. Combining concepts from topological physics with the dependence of the SHE on the spin Berry curvature (SBC) of the electronic bands, we propose a simple strategy to rapidly search for materials with large intrinsic SHEs based on the following ideas: High symmetry combined with heavy atoms gives rise to multiple Dirac-like crossings in the electronic structure; without sufficient symmetry protection, these crossings gap due to spin-orbit coupling; and gapped crossings create large SBC.

Abstract
AIM To evaluate the role of MRI in preoperative assessments of patients with a persistent cloaca and compare magnetic resonance imaging (MRI) versus fluoroscopy contrast study in the accuracy of common canal measurement and classification prediction. MATERIALS AND METHODS Thirty-one patients with a persistent cloaca were diagnosed and treated at Guangzhou Women and Children's Medical Center between March 2011 and December 2017. The length of the common canal was measured using MRI and fluoroscopy contrast study. Classification results based on measurements were compared with cystoscopy and intraoperative findings. The accuracy in predicting the classification by measuring the common canal length was compared. RESULT Among 31 patients, 24 had MRI, 24 underwent fluoroscopy contrast study, and 25 underwent cystoscopy. In 20 patients, MRI-based categorisations were in accordance with cystoscopy or surgery findings, whereas in four patients there was discordance. In 17 patients, categorisations based on fluoroscopy contrast study were in accordance with cystoscopy or surgery findings, and in seven patients there was discordance; the difference was not statistically significant (p>0.05). CONCLUSION MRI may accurately demonstrate genitourinary anomalies and the length of the common canal in patients with persistent cloaca. Categorisation based on MRI measurements of the common canal was accordant with the results from cystoscopy and findings from surgery. The use of this method may help surgeons to develop appropriate reconstruction plans before sending their patients to the operating room.

Abstract
Objective:To explore the anti-tumor effect of Stat3 antisense oligodeoxynucleotide on human Hep-2 cell tumor-bearing BALB/c nude mouse, to study the therapeutic value of Stat3 antisense oligodeoxynucleotide on laryngeal cancer. Method:Hep-2 cells from human laryngeal carcinoma in logarithmic phase were inoculated subcutaneously into BALB/c mice to establish a model of human Hep-2 cell tumor-bearing BALB/c mice. They were divided into blank group, control group and different concentrations of AS3 groups(1 group, 2 group, 3 group, 4 group), and then intraperitoneally administered once a day for 4 weeks, measuring body weight twice a week, and the long and short diameters of the tumors were recorded. After 4 weeks, the mice in each group were weighted. The subcutaneous transplanted tumors were dissected, weighted, and inhibitory rate was obtained.Result:Stat3 antisense oligodeoxynucleotide can obviously inhibited the growth of human Hep-2 cell tumor-bearing BALB/c mice with the concentration of antisense oligodeoxynucleotide heightened. The IR in different concentration AS3 groups was obviously higher than that in the control group(P<0.01) .Conclusion:Stat3 antisense oligodeoxynucleotide can obviously inhibit the growth of subcutaneous transplanted tumors in human Hep-2 cell tumor-bearing BALB/c mice, and may have therapeutical effect on laryngeal cancer.

Abstract
PURPOSE This study aimed to evaluate the effectiveness of preclinical training on ceramic crown preparation using digital training system compared with traditional training method. MATERIALS AND METHODS A sample of 66 participating fourth-year undergraduate dental students were randomly assigned to one of two groups for ceramic crown preparation: experimental group as trained using digital method with Online Peer-Review System (OPRS) and Real-time Dental Training and Evaluation System (RDTES); control group as trained using traditional method with instructor demonstration and evaluation. At the completion of training periods, both groups performed the preparation of ceramic crown of upper left central incisor, which were blindly scored by the experienced instructors under the pre-defined assessment criteria. The results of both were compared using Student's t-test or Wilcoxon signed rank test. The level of significance was P < .05. The questionnaires regarding the benefits or drawbacks of digital training system were answered by the students of experimental group. RESULTS Five of 15 items in the assessment outcome of the digital group were significantly better than the traditional group. The questionnaire results from the students of the experimental group indicated 96.97% of the students agreed or strongly agreed that using digital training system could better improve the practical ability than traditional method. The total scores of practical results were significantly positively correlated with the points of the questionnaires. CONCLUSION The digital training system with OPRS and RDTES might be a good alternative to the traditional training method in the preclinical course of dental practice.

Abstract
BACKGROUND To report the co-existence of novel biallelic PDE6A mutations and heterozygous RPGR mutation in a Chinese female patient with retinitis pigmentosa (RP), and to analyze the intrafamilial phenotypic diversity. METHODS Three patients with retinopathy and four healthy family members were included in genetic and clinical analyses. Personal medical records were obtained from another four unaffected female family members who refused blood donation. Family history was carefully recorded. Each patient received comprehensive ophthalmic tests. Targeted next-generation sequencing (NGS) approach was performed on the proband to determine the retinopathy causative mutation for this family. In silico analysis was also applied to analyze the pathogenesis of identified mutations. RESULTS The two recruited male patients were diagnosed with RP, and the female patient RP sine pigmento (RPSP). Genetic assessments revealed a recurrent RPGR mutation, c.1926_1927insA, carried by all three patients and segregated the disease status. Three other unaffected female family members were confirmed as carriers for the identified RPGR mutation, and another four as obligate carriers. Interestingly, of all the eight female RPGR mutation carriers in this family, only one female developed retinal dystrophy. Comprehensive genetic analysis of this patient unraveled additional biallelic PDE6A mutations, c.[1066-9delT];[2324delG], carried solely by this individual. CONCLUSIONS Taken together, we hypothesize that the phenotypic variability presented by female RPGR mutation carriers may be attributed to the co-existence of other disease-causative mutations. Our study also emphasizes the importance of comprehensive genetic analysis in these female carriers, which will contribute to better diagnosis, prognosis, and treatment for these patients.

Abstract
BACKGROUND Anti-melanoma differentiation-associated gene 5 (MDA5) dermatomyositis (DM) is a distinctive subtype of DM that carries a significant risk of interstitial lung disease (ILD). The mechanisms remain elusive. OBJECTIVES To explore the role of the type I interferon (IFN) system in the pathogenesis of anti-MDA5 DM. METHODS Twenty patients with anti-MDA5 DM were studied and compared with patients with anti-aminoacyl-tRNA synthetase (ARS) DM (n = 10) and autoantibody-negative patients with DM (n = 20). The levels of inflammatory cytokines, B-cell-activating factor (BAFF) and Krebs von den Lungen (KL)-6 in blood were tested by enzyme-linked immunosorbent assay and multiplex assays. Expressions of transcripts for IFN-associated sensors and type I IFN-inducible genes in peripheral blood mononuclear cells (PBMCs) were detected by real-time polymerase chain reaction. Expressions of the signal transducer and activator of transcription (STAT)1, interferon-stimulated gene (ISG)15 and MxA proteins in skin lesions were analysed by immunohistochemistry. RESULTS Plasma IFN-α levels were significantly increased in patients with anti-MDA5 DM. PBMCs from patients with anti-MDA5 DM showed significant upregulation of the TLR3, TLR7, IFIH1 and DDX58 genes, as well as serial IFN-inducible genes. Skin biopsies from patients with anti-MDA5 DM were characterized by strong expression of the STAT1, ISG15 and MxA proteins. In the patients with anti-MDA5 DM and ILD with high IFN-α production, there was a positive quantitative correlation between IFN-α and BAFF (rs = 0·63, P = 0·044). In addition, the higher levels of BAFF paralleled the higher concentrations of KL-6 (rs = 0·86, P = 0·0012). CONCLUSIONS Our data confirm the aberrant activation of the type I IFN system in anti-MDA5 DM. Overproduction of IFN-α linked with BAFF may be implicated in the development of ILD.

Abstract
A lightweight composite bridge deck system composed of steel orthotropic deck stiffened with thin Ultra-High Performance Concrete (UHPC) layer has been proposed to eliminate fatigue cracks in orthotropic steel decks. The debonding between steel deck and UHPC layer may be introduced during construction and operation phases, which could cause adverse consequences, such as crack-induced water invasion and distinct reduction of the shear resistance. The piezoelectric lead zirconate titanate (PZT)-based technologies are used to detect interfacial debonding defects between the steel deck and the UHPC layer. Both impedance analysis and wave propagation method are employed to extract debonding features of the steel-UHPC composite slab with debonding defect in different sizes and thicknesses. Experimental tests are performed on two steel-UHPC composite slabs and a conventional steel-concrete composite deck. Additionally, an improved Particle Swarm Optimization (PSO)-k-means clustering algorithm is adopted to obtain debonding patterns based on the feature data set. The laboratory tests demonstrate that the proposed approach provides an effective way to detect interfacial debonding of steel-UHPC composite deck.

Abstract
BACKGROUND AND PURPOSE Impaired lung function is regarded as a risk factor for stroke in patients with chronic obstructive pulmonary disease. However, the association between reduced lung function and incident stroke in a community-based population with sleep-disordered breathing (SDB) remains unknown. METHODS A prospective study was performed within the Sleep Heart Health Study cohort. Full montage home sleep testing and spirometry data on 2082 and 2072 individuals with and without SDB, respectively, were analysed. Cox proportional hazards regression models were used to estimate the association between lung function and incident stroke. RESULTS Over 11.7 years, 183 cases of stroke were identified in participants without pre-existing cardiovascular diseases, including 71 and 112 with an apnoea-hypopnoea index <5 events/h and ≥5 events/h, respectively. In the entire population, lung function was inversely associated with incident stroke [hazard ratio (HR) 0.913 (95% confidence interval 0.839-0.994) for every 10% increase in percentage of predicted forced vital capacity]. When the population was divided according to the presence/absence of SDB, the association of lung function with incident stroke became stronger in individuals with SDB [HR 0.899 (0.822-0.984) for every 10% increase in percentage of predicted forced expiratory volume in 1 s; HR 0.881 (0.787-0.987) for every 10% increase in percentage of predicted forced vital capacity] but not in individuals without SDB. CONCLUSIONS Lung function may serve as a risk factor for incident stroke in a community-based population, especially in those with SDB. Spirometry may help improve the risk management for primary care in community-based populations.

Abstract
Objective: To evaluate the visual outcomes of patients with visual impairment after resecting skull base tumor via an endoscopic endonasal approach, and to analyze the factors affecting visual recovery. Methods: One hundred and fifty-three patients with skull base tumor who suffered from preoperative visual impairment from Skull Base Surgery Center of Xuanwu Hospital were operated through an endoscopic endonasal approach. Both preoperative and postoperative visual function outcomes as well as factors that might have affected their visual recovery were analyzed retrospectively by Chi square test and Logistic regression analysis. Results: Complete resection was achieved in 85.6% of the patients using this technique. The rate of postoperative visual recovery in the female group (86.1%) was higher than that in the male group (73.9%), the benign group (90.2%) higher than the malignant group (20.0%), the group without optic atrophy (97.1%) higher than the one with (51.2%), and the acute group (96.6%) higher than the chronic group (80.0%). Significant differences were found between the abovementioned groups (χ(2) value was 5.849, 87.860, 79.757, 4.745, respectively, all P<0.05). The degree of optic atrophy and the property of tumors were significantly associated with visual improvement after treatment (Wold χ(2) value was 18.597 and 35.623, all P<0.001). Conclusions: Our results indicate that endoscopic endonasal surgery shows its ability both to resect skull base tumors and to improve visual function in the majority of patients. The timing of treatment for patients suffered from preoperative visual impairment should be selected in early stage before optic atrophy occurs.

HLA-DQA1-HLA-DRB1 polymorphism is a major predictor of azathioprine-induced pancreatitis in patients with inflammatory bowel disease. Aliment Pharmacol Ther 2018; 47:615-620. [PMID: 29270995 DOI: 10.1111/apt.14483] [Citation(s) in RCA: 45] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2017] [Revised: 11/15/2017] [Accepted: 12/03/2017] [Indexed: 12/11/2022]
Abstract
BACKGROUND Azathioprine (AZA)-induced pancreatitis is an unpredictable and dose-independent adverse event affecting 2%-7% of patients with inflammatory bowel disease (IBD) patients treated with AZA. There are no tools in clinical practice to identify at-risk individuals; however, a genome wide association study (GWAS) identified a strong association between the Class II HLA gene region polymorphism (rs2647087) and thiopurine-induced pancreatitis. AIM To independently confirm the findings of the GWAS in an IBD cohort, to evaluate its utility in clinical practice and to offer a novel AZA treatment algorithm for IBD based on pharmacogenomic principles. METHODS A retrospective cohort study evaluated 373 AZA-exposed IBD patients from a tertiary care academic centre in London, Canada. Due to the limited number of patients taking mercaptopurine (MP), such patients were not included this cohort. All subjects underwent screening for the single nucleotide polymorphism (SNP) rs2647087 mapped to the HLA-DQA1*02:01-HLA-DRB1*07:01 haplotype and were sub-divided based on the presence (n = 13) or absence (n = 360) of an AZA-induced pancreatitis diagnosis. The risk of AZA-induced pancreatitis was assessed based on rs2647087 genotype. RESULTS The risk of pancreatitis during AZA-therapy was highly predictable and genotype dependent: 0.53% for wild type (A/A), 4.25% (OR = 4.19, 95% CI 1.02-36.45, P = 0.044) for heterozygous (A/C), and 14.63% (OR = 15.83, 95% CI 3.80-145.26, P = 0.0001) for homozygous variant (C/C) patients. CONCLUSIONS The class II HLA region (at rs2647087) is an important marker of AZA-induced pancreatitis risk. We propose a simple and clinically implementable algorithm based on rs2647087 and TPMT genotypes for AZA selection and dosing for patients with IBD.

Abstract
BACKGROUND AND PURPOSE Hematoma expansion is an independent determinant of poor clinical outcome in intracerebral hemorrhage. Although the "spot sign" predicts hematoma expansion, the identification requires CT angiography, which limits its general accessibility in some hospital settings. Noncontrast CT, without the need for CT angiography, may identify sites of active extravasation, termed the "swirl sign." We aimed to determine the association of the swirl sign with hematoma expansion. MATERIALS AND METHODS Patients with spontaneous intracerebral hemorrhage between 2007 and 2014 who underwent an initial and subsequent noncontrast CT at a single center were retrospectively identified. The swirl sign, on noncontrast CT, was defined as iso- or hypodensity within a hyperdense region that extended across 2 contiguous 5-mm axial CT sections. RESULTS A total of 212 patients met the inclusion criteria. The swirl sign was identified in 91 patients with excellent interobserver agreement (κ = 0.87). The swirl sign was associated with larger initial hematoma (P < .001) and earlier initial CT (P < .001) and hematoma expansion (P = .028). Multivariable regression modeling demonstrated that if one assumed similar initial hematoma volume, onset-to-first scan, and time between CT scans, the median absolute hematoma growth was 5.77 mL (95% CI, 2.37-9.18 mL; P = .001) and relative growth was 35.6% (95% CI, 18.5%-52.6%; P < .001) higher in patients with the swirl sign compared with those without. CONCLUSIONS The NCCT swirl sign was reliably identified and is associated with hematoma expansion. We propose that the swirl sign be included in risk stratification of intracerebral hemorrhage and considered for inclusion in clinical trials.

Abstract
BACKGROUND AND PURPOSE This study aimed to assess the evolution of perinodular and contralateral white matter abnormalities in patients with periventricular nodular heterotopia (PNH) and epilepsy. METHODS Diffusion tensor imaging (DTI) (64 directions) and 3 T structural magnetic resonance imaging were performed in 29 PNH patients (mean age 27.3 years), and 16 patients underwent a second scan (average time between the two scans 1.1 years). Fractional anisotropy and mean diffusivity were measured within the perilesional and contralateral white matter. RESULTS Longitudinal analysis showed that white matter located 10 mm from the focal nodule displayed characteristics intermediate to tissue 5 mm away, and normal-appearing white matter (NAWM) also established evolution profiles of perinodular white matter in different cortical lobes. Compared to 29 age- and sex-matched healthy controls, significant decreased fractional anisotropy and elevated mean diffusivity values were observed in regions 5 and 10 mm from nodules (P < 0.01), whilst DTI metrics of the remaining NAWM did not differ significantly from controls. Additionally, normal DTI metrics were shown in the contralateral region in patients with unilateral PNH. CONCLUSIONS Periventricular nodular heterotopia is associated with microstructural abnormalities within the perilesional white matter and the extent decreases with increasing distance from the nodule. In the homologous contralateral region, white matter diffusion metrics were unchanged in unilateral PNH. These findings have clinical implications with respect to the medical and surgical interventions of PNH-related epilepsy.

Abstract
We investigated the influence of apolipoprotein B gene (APOB) variants on the risk of hyperlipidemia (HL) in 631 middle-aged and elderly members of the Chinese Yugur population (HL, n=336; normolipidemia, n=295). APOB polymorphisms were identified using mass spectrometry, and five single nucleotide polymorphisms (rs1042034, rs2163204, rs512535, rs676210, and rs679899) and serum lipids were further analyzed. rs1042034 and rs676210 were significantly associated with HL (P<0.05). Compared with the GG or AA genotype, individuals with AG and AG+AA in rs1042034 and with AG and AG+GG in rs676210 had a 1.67-fold (95%CI=1.20-2.33),1.63-fold (95%CI=1.19-2.24), 1.72-fold (95%CI=1.24-2.40), and 1.67-fold (95%CI=1.21-2.291) increased risk of high HL, respectively. rs2163204 was in strong linkage disequilibrium with rs1042034, rs676210, and rs679899, and strong disequilibrium was observed between rs1042034 and rs676210 (D'>0.9). Compared with the GTGAA haplotype, haplotypes ATGGA and ATAGG were more strongly associated with HL [odds ratio (OR)=1.46, 95%CI=0.02-2.11; OR=1.63, 95%CI=1.03-2.60, respectively]. The risk factors age (P=0.008), body mass index (P<0.0001), GA+GG genotype in rs676210 (P=0.009), and alcohol consumption (P=0.056) contributed strongly to HL development. The A allele of rs1042034 and the G allele of rs676210 may thus predispose middle-aged and elderly members of the Chinese Yugur population to HL in combination with other genetic or nutritional factors, and could be used as new genetic markers for HL screening.

Abstract
Objective: To explore the effect of peripheral blood genomic DNA methylation on the relationship between methyl donor status and risk of breast cancer. Methods: A case-control study was conducted. Each three hundred breast cancer cases and controls were consecutively recruited. Food frequency questionnaire was used to collect dietary information. Amounts on folate, methionine, choline and betaine intake were calculated. Blood samples were collected for DNA extraction. Peripheral blood genomic DNA methylation was measured by using the Methyl Flash(TM) Methylated DNA Quantification Kit. Pathway analysis was used to examine the effect of genomic DNA methylation on the relations between methyl donor status and risk of breast cancer. Results: The genome DNA methylation rates were 0.46%±0.25% and 0.53%±0.34%, respectively on both cases and controls, with differences statistically significant (P<0.01). Results from the pathway analysis, results showed that methionine consumption was related to genomic DNA methylation (β=0.065, P<0.05) while genomic DNA methylation was related to the risk of breast cancerk (β=-0.027, P<0.05), respectively. Conclusions: The level of peripheral blood genomic DNA methylation in breast cancer cases was significantly lower than that in the controls. Genomic DNA methylation seemed to have played a mediated role between methionine and the risk of breast cancer.

Abstract
Objective: To explore the role of neutrophil extracellular traps (NETs)-induced endothelial cell damage in the pathogenesis of dermatomyositis (DM)-associated interstitial lung disease(ILD). Methods: Serum free DNA and krebs von den lungen-6 (KL-6) level were tested in healthy controls, dermatomyositis patients with or without interstitial lung disease (DM-ILD and DM-NILD). Subjects' peripheral blood neutrophils were stimulated with phorbol 12-myristate 13-acetate (PMA), then human umbilical vein endothelial cells (HUVECs) were co-cultured with NETs. The cell morphology was observed by the inverted phase contrast microscope. Cell viability was detected by cell counting kit-8 (CCK8). Results: The concentration of serum free DNA in DM patients [(271.27± 76.53) μg/L] was significantly higher than that in health control (HC)[(152.89±37.34) μg/L, P<0.001]. Moreover, free DNA level in DM-ILD patients [(302.67±74.15) μg/L] was higher than that in DM-NILD patients [(235.59±63.55 ) μg/L, P<0.005]. The concentration of KL-6in DM patients [(3.08±2.07) μg/L]was higher than that in HC[(0.87±0.51) μg/L, P<0.001]. Similarly, KL-6 in DM-ILD patients [(4.00±2.44) μg/L ] was higher than that of DM-NILD patients [(2.03±0.61) μg/L, P<0.005]. Free DNA and KL-6 were positively correlated (r=0.251, P<0.05). The survival of endothelial cells in DM group (53±11)% was lower than that of HC group [(70±5)%, P<0.001]. Not surprisingly, the survival of endothelial cells in DM-ILD group (44±4) % was lower than that in DM-NILD group [(61±8)%, P<0.01]. Conclusion: NETs could play an important role in the pathogenesis of dermatomyositis associated interstitial lung disease, suggesting that NETs may be the potential therapeutic target.

Abstract
Objective: To investigate the effect of corticotomy-facilitated orthodontics on the treatment time and final outcome in skeletal class Ⅱ division 1 patients. Methods: Twenty adult skeletal class Ⅱ division 1 patients treated with two maxillary first premolar extractions were included and randomly divided into two groups (the corticotomy group and the control group). The treatment time was recorded and the changes of soft and hard tissue were compared by using three-dimensional measurement and analysis of cone-beam CT images before and after treatment. Results: There was no significant difference in the alignment time between two groups, while the time of maxillary space closure and the total treatment time in corticotomy group ([5.8±1.3] and [24.9±5.1] months, respectively) were shorter than that in the control group ([9.9±1.1] and [30.8±4.6] months, respectively) and the differences were significant (P<0.01). In the corticotomy group, the retraction amount of the upper central in cisal margin, apical tip, supradentale, labrale superius and the increase of nasolabial angle were greater than those in the control group (P<0.05). Conclusions: In patients with mild to moderate skeletal class Ⅱ division 1 malocclusion, corticotomy-facilitated orthodontics can not only shorten the treatment time, but is more conductive to the retraction of upper anterior teeth and improvement of the profile.

Abstract
OBJECTIVE Articular chondrocyte activation, involving aberrant proliferation and prehypertrophic differentiation, is essential for osteoarthritis (OA) initiation and progression. Disruption of mechanistic target of rapamycin complex 1 (mTORC1) promotes chondrocyte autophagy and survival, and decreases the severity of experimental OA. However, the role of cartilage mTORC1 activation in OA initiation is unknown. In this study, we elucidated the specific role of mTORC1 activation in OA initiation, and identify the underlying mechanisms. METHOD Expression of mTORC1 in articular cartilage of OA patients and OA mice was assessed by immunostaining. Cartilage-specific tuberous sclerosis complex 1 (Tsc1, mTORC1 upstream inhibitor) knockout (TSC1CKO) and inducible Tsc1 KO (TSC1CKOER) mice were generated. The functional effects of mTORC1 in OA initiation and development on its downstream targets were examined by immunostaining, western blotting and qPCR. RESULTS Articular chondrocyte mTORC1 was activated in early-stage OA and in aged mice. TSC1CKO mice exhibited spontaneous OA, and TSC1CKOER mice (from 2 months) exhibited accelerated age-related and DMM-induced OA phenotypes, with aberrant chondrocyte proliferation and hypertrophic differentiation. This was associated with hyperactivation of mTORC1 and dramatic downregulation of FGFR3 and PPR, two receptors critical for preventing chondrocyte proliferation and differentiation. Rapamycin treatment reversed these phenotypes in KO mice. Furthermore, in vitro rescue experiments demonstrated that p73 and ERK1/2 may mediate the negative regulation of FGFR3 and PPR by mTORC1. CONCLUSION mTORC1 activation stimulates articular chondrocyte proliferation and differentiation to initiate OA, in part by downregulating FGFR3 and PPR.

Abstract
Tantalum arsenide is a member of the noncentrosymmetric monopnictides, which are putative Weyl semimetals. In these materials, three-dimensional chiral massless quasiparticles, the so-called Weyl fermions, are predicted to induce novel quantum mechanical phenomena, such as the chiral anomaly and topological surface states. However, their chirality is only well defined if the Fermi level is close enough to the Weyl points that separate Fermi surface pockets of opposite chirality exist. In this Letter, we present the bulk Fermi surface topology of high quality single crystals of TaAs, as determined by angle-dependent Shubnikov-de Haas and de Haas-van Alphen measurements combined with ab initio band-structure calculations. Quantum oscillations originating from three different types of Fermi surface pockets were found in magnetization, magnetic torque, and magnetoresistance measurements performed in magnetic fields up to 14 T and temperatures down to 1.8 K. Of these Fermi pockets, two are pairs of topologically nontrivial electron pockets around the Weyl points and one is a trivial hole pocket. Unlike the other members of the noncentrosymmetric monopnictides, TaAs is the first Weyl semimetal candidate with the Fermi energy sufficiently close to both types of Weyl points to generate chiral quasiparticles at the Fermi surface.

Abstract
Topological quantum materials represent a new class of matter with both exotic physical phenomena and novel application potentials. Many Heusler compounds, which exhibit rich emergent properties such as unusual magnetism, superconductivity and heavy fermion behaviour, have been predicted to host non-trivial topological electronic structures. The coexistence of topological order and other unusual properties makes Heusler materials ideal platform to search for new topological quantum phases (such as quantum anomalous Hall insulator and topological superconductor). By carrying out angle-resolved photoemission spectroscopy and ab initio calculations on rare-earth half-Heusler compounds LnPtBi (Ln=Lu, Y), we directly observe the unusual topological surface states on these materials, establishing them as first members with non-trivial topological electronic structure in this class of materials. Moreover, as LnPtBi compounds are non-centrosymmetric superconductors, our discovery further highlights them as promising candidates of topological superconductors. Heusler compounds have been predicted to host topological order with other emergent properties, which yet awaits for experimental evidence. Here, Liu et al. report a direct observation of topological surface states on half-Heusler compounds LnPtBi.

[PMID: 27540720 PMCID: PMC5350992 DOI: 10.1111/cts.12409] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2016] [Revised: 06/13/2016] [Accepted: 07/12/2016] [Indexed: 01/05/2023] Open
Abstract
This meta‐analysis was conducted to estimate the association between matrix metalloproteinase‐1 (MMP‐1) expression and pelvic organ prolapse (POP) in women. Relevant studies published before 6 December 2015 were identified by searching PubMed, Ovid, EBSCO, and EMBASE. A total number of five case–control studies, including 182 POP cases and 192 controls, were identified. The results indicated that women without POP had a lower MMP‐1 level of expression compared with women with POP (odds ratio = 0.54, 95% confidence interval: 0.43–0.67, P = 0.000). After stratification by biopsy site, ethnicity, or menopausal status, this finding was also confirmed in the subgroup analysis with no significant changes. Egger's linear regression test revealed a potential publication bias (P = 0.028). The findings of our study indicate that women who suffer from POP have a higher expression level of MMP‐1 than women without POP.

[PMID: 27500892 DOI: 10.1111/odi.12566] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2015] [Revised: 07/06/2016] [Accepted: 07/18/2016] [Indexed: 11/29/2022]
Abstract
OBJECTIVE To investigate the influence of maxillary impacted canines on the root morphology of adjacent premolars in a Chinese population. SUBJECTS AND METHODS A sample of 370 Chinese subjects with maxillary canine impaction and 370 control subjects were collected in this study. CBCT data of all subjects were collected and analyzed. The prevalence of separate-rooted maxillary premolars was compared between subjects with and without impacted canines. Then, the prevalence of separate-rooted maxillary premolars was compared between subjects with buccal canine impaction (BIC) and those with palatal impaction (PIC). RESULTS The prevalence of separate-rooted first premolars was significantly higher in the canine impaction group (P = 0.046), but the prevalence of separate-rooted second premolars was not different (P = 0.780). Furthermore, a significant higher prevalence of first premolar root separation was found on the impacted site in the BIC subgroup (P < 0.001), but not in the PIC subgroup (P = 0.508). Also, the prevalence of separate-rooted first premolars in the BIC subgroup was significantly higher than that of the control group (P = 0.008), but not so for the PIC subgroup (P = 0.097). CONCLUSIONS Buccally impacted maxillary canines are associated with an increased prevalence of root separation in the adjacent maxillary first premolars. This is likely because that buccally impacted canines encroach on the space needed for root development of the first premolars.
