Abstract
Non-alcoholic steatohepatitis (NASH) is a form of non-alcoholic fatty liver disease (NAFLD) characterized by steatosis, inflammation, and fibrosis often associated with metabolic syndrome. Fibroblast growth factor 15 (FGF15), an endocrine factor mainly produced in the distal part of small intestine, has emerged to be a critical factor in regulating bile acid homeostasis, energy metabolism, and liver regeneration. We hypothesized that FGF15 alters the development of each of the listed features of NASH. To test this hypothesis, four-week old male Fgf15-/- and their corresponding wild-type (WT) mice were fed either a high fat diet (HFD) or a control chow diet for six months. The results confirmed that HFD feeding for six months in WT mice recapitulated human NASH phenotype, including macrovesicular steatosis, inflammation, and fibrosis. Whereas FGF15 deficiency had no effect on the severity of liver steatosis or inflammation, it was associated with decreased liver fibrosis. Furthermore, FGF15 deficiency resulted in abnormal bile acid homeostasis, increased insulin resistance, increased HFD-induced serum triglycerides, decreased inductions of hepatic cholesterol content by HFD, and altered gene expression of lipid metabolic enzymes. These data suggest that FGF15 improves lipid homeostasis and reduces bile acid synthesis, but promotes fibrosis during the development of NASH.

Abstract
Acute appendicitis is the most common condition that presents with an acute abdomen needing emergency surgery. Despite this common presentation, correctly diagnosing appendicitis remains a challenge as clinical signs or positive blood results can be absent in 55% of the patients. The reported proportion of missed diagnoses of appendicitis ranges between 20% and 40%. A delay or mis-diagnosis of appendicitis can result in severe complications such as perforation, abscess formation, sepsis, and intra-abdominal adhesions. Literature has shown that patients who had a negative appendectomy suffer post-op complications and infections secondary to hospital stays; there have even been reported cases of fatality. It is therefore crucial that timely and accurate diagnosis of appendicitis is achieved to avoid complications of both non-operating as well as unnecessary surgical intervention. The aim of this review is to systematically report and analyse the latest evidence on the different approaches used in diagnosing appendicitis. We include discussions of clinical scoring systems, laboratory tests, latest innovative bio-markers and radiological imaging.

Abstract
BACKGROUND Relapse of granulomatous epulis is common after surgery because of local irritations, hormonal level in vivo, or incomplete resection. Currently, if recurrence occurs, then extraction of the teeth adjacent to the lesion is commonly performed, which may influence the aesthetics or masticatory function. Thus, a more effective and less aggressive treatment method is urgently demanded, particularly for the recurring lesion. This study investigated the effects of the intralesional pingyangmycin (PYM) injections for the recurrent granulomatous epulis and assessed the complications. MATERIAL AND METHODS A total of 16 patients with recurrent granulomatous epulis underwent intralesional PYM injections, between July 2010 and June 2014. The effects and complications of the treatment were retrospectively reviewed. RESULTS The total number of injections performed was 48 (for all patients). The median number of injections per patient was three (range, two to four). All cases completely recovered with no recurrence and resorption of the alveolar bone after a follow-up of more than 12 months. The complications included slight bleeding, local swelling and pain following injection. All these symptoms resolved 7 to 10 days after the injection. CONCLUSIONS In summary, intralesional PYM injections may be a preferred option for recurring granulomatous epulis.

Abstract
OBJECTIVES To evaluate the diagnostic value of serum p16 gene promoter methylation for diagnosis of nonsmall cell lung cancer (NSCLC). MATERIALS AND METHODS By searching the databases of PubMed and CNKI, we included all the published articles related serum p16 gene promoter methylation and nonsmall lung cancer. The true positive, false positive, false negative, and true negative data for each included publication were extracted by the reviewers. The diagnostic sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and area under the receiver operating characteristic (ROC) were pooled by MetaDiSc1.4 software. RESULTS Finally, 13 manuscripts with 1440 subjects were involving in this diagnostic meta-analysis. The pooled sensitivity and specificity were 0.25 (95% confidence interval [CI]: 0.18-0.32) and 0.95 (95% CI: 0.93-0.97), respectively, with randomized effect model. The pooled positive likelihood ratio and negative likelihood ratio were 5.08 (95% CI: 3.00-8.62) and 0.69 (95% CI: 0.62-0.77) with fixed effect model and randomized effect model, respectively. The diagnostic ROC curve for the included 13 publications was pooled by statistical software MetaDiSc14.0 according to the Bayes theorem. The pooled area under the ROC was 0.72 with its standard error of 0.10. CONCLUSION According to the published articles, high specificity and low sensitivity were found in this meta-analysis for the p16 gene promoter methylation in the diagnosis of NSCLC.

Abstract
Background: To determine the therapeutic efficacy and cost-effective of pancreatic kininogenase (PKase) on treatment of diabetic peripheral neuropathy (DPN) compared with Prostaglandin E1 (PGE1) in patients with type 2 diabetes. Methods: 104 patients with DPN receiving standard glucose control therapy were randomly assigned into 3 groups: Group-A received PKase treatment, Group-B received PGE1 treatment, and Group-C received only standard glucose control therapy. Michigan neuropathy screening instrument (MNSI) score, neurophysiology examination, and nerve conduction velocity were measured. Results: Standard glucose control therapy significantly reduced hyperglycemia to a similar level in all groups. Questionnaire grading and neurophysiology examination both indicated that no significant difference was found at the end of treatment between Groups -A and -B. Except for the ulnar nerve sensory conduction velocity that was significantly improved in Group-B, the remaining nerve conduction velocity (regardless of sensory or motor nerve conduction velocities) was improved to a similar level in Groups -A and -B. Group-A had significantly reduced questionnaire grading and better improvement in motor nerve conduction velocity of the common peroneal nerve, ulnar nerve, and sensory nerve conduction velocity of the sural nerve as compared with Group-C. However, the medical cost of PKase was only 18.9% of that of PGE1 during one course of treatment. Conclusions: PKase has the similar therapeutic efficacy as PGE1 on treatment of DPN in patients with type 2 diabetes. However, the medical cost of PKase is one fifth of that of PGE1. Thus, PKase is a cost-effective drug for treatment of DPN.

Abstract
Intensity-modulated radiotherapy (IMRT) is increasingly used in order to minimize the gastrointestinal, genitourinary, and hematological toxicity in cervical and uterine cancers. However, the benefit of this high-precision approach is detracted by the margins applied to the clinical target volume (CTV) to generate the planning tumor volume (PTV), taking into account tumor and surrounding organs movements, deformations, and volume changes. Adequate PTV margins should be large enough to prevent geographical misses, but not excessive, which might end the benefit from IMRT. The objectives of this review were: (a) to present the evidence available for the determination of CTV-PTV margin for uterine cancers; (b) to highlight the impact of these margins in the context of adaptive radiotherapy; and (c) to discuss the role of the PTV concept in intracavitary brachytherapy.

Abstract
Oral squamous cell carcinoma (OSCC) is the most common cancer of the head and neck and is associated with a high rate of lymph node metastasis. The initial step in the metastasis and transition of tumors is epithelial-mesenchymal transition (EMT)-induced angiogenesis, which can be mediated by angiopoietin 2 (ANG2), a key regulatory factor in angiogenesis. In the present study, immunohistochemistry and real-time quantitative reverse transcriptase (qRT-PCR) were used to measure the expression of ANG2 in OSCC tissues. Plasmids encoding ANG2 mRNA were used for increased ANG2 expression in the OSCC cell line TCA8113. The short interfering RNA (siRNA)-targeting ANG2 mRNA sequences were used to inhibit ANG2 expression in TCA8113 cells. Subsequently, transwell assays were performed to examine the effects of ANG2 on TCA8113 cell migration and invasion. Furthermore, in vivo assays were performed to assess the effect of ANG2 on tumor growth. Terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) assays and immunohistochemistry were used to examine cell apoptosis and angiogenesis in tumor tissues, respectively. Finally, western blot analysis was performed to evaluate tumor formation-related proteins in OSCC tissues. We found that protein expression of ANG2 was remarkably upregulated in OSCC tissues. Overexpression of ANG2 increased the migration and invasion of TCA8113 cells by regulating EMT. Further investigations showed that overexpression of ANG2 increased tumor growth in nude mice, and angiogenesis of OSCC tissues increased in the presence of ANG2 overexpression. Overexpression of ANG2 also reduced cell apoptosis in tumor tissue cells. Finally, we found that overexpression of ANG2 resulted in changes in the expression of tumor formation-related proteins including vimentin, E-cadherin, Bim, PUMA, Bcl-2, Bax, Cyclin D1, PCNA and CD31. Our findings show that ANG2 has an important role in the migration and invasion of OSCC. More importantly, further investigations suggested that overexpression of ANG2 might increase OSCC metastasis by promoting angiogenesis in nude mice. This stimulatory effect could be achieved by inducing abnormal EMT and by reducing apoptosis and increasing proliferation of cells.

Abstract
Cement (polymethylmethacrylat) is frequently and increasingly used in vertebral surgery. Complications can occur by spillage of this material; however the vast majority of the patients remain free of symptoms and do not require any specific therapy.Internists, gastroenterologists and radiologists regularly performing abdominal ultrasound and computed tomography should be aware of this complication.A case of spillage of cement in the right hepatic vein is presented.

Abstract
X-linked intellectual disability (XLID) is a clinically and genetically heterogeneous disorder. During the past two decades in excess of 100 X-chromosome ID genes have been identified. Yet, a large number of families mapping to the X-chromosome remained unresolved suggesting that more XLID genes or loci are yet to be identified. Here, we have investigated 405 unresolved families with XLID. We employed massively parallel sequencing of all X-chromosome exons in the index males. The majority of these males were previously tested negative for copy number variations and for mutations in a subset of known XLID genes by Sanger sequencing. In total, 745 X-chromosomal genes were screened. After stringent filtering, a total of 1297 non-recurrent exonic variants remained for prioritization. Co-segregation analysis of potential clinically relevant changes revealed that 80 families (20%) carried pathogenic variants in established XLID genes. In 19 families, we detected likely causative protein truncating and missense variants in 7 novel and validated XLID genes (CLCN4, CNKSR2, FRMPD4, KLHL15, LAS1L, RLIM and USP27X) and potentially deleterious variants in 2 novel candidate XLID genes (CDK16 and TAF1). We show that the CLCN4 and CNKSR2 variants impair protein functions as indicated by electrophysiological studies and altered differentiation of cultured primary neurons from Clcn4(-/-) mice or after mRNA knock-down. The newly identified and candidate XLID proteins belong to pathways and networks with established roles in cognitive function and intellectual disability in particular. We suggest that systematic sequencing of all X-chromosomal genes in a cohort of patients with genetic evidence for X-chromosome locus involvement may resolve up to 58% of Fragile X-negative cases.

Abstract
Adhesion of tumor cells (TCs) to polymorphonuclear neutrophils (PMNs) tethered on a monolayer of vascular endothelial cells (ECs) in shear flows is investigated theoretically. Both TC—PMN and PMN—EC aggregations are modeled using the population balance equations (PBEs). Parameters in the model obtained by curve fitting show that an increase of shear rate or viscosity will suppress the formation of aggregates and promote the breakage of them. Analysis on the collision frequency suggests that the averaged encounter duration is affected by viscosity. Based on the model, a nonlinear connection between the number of migrated TCs and the concentration of PMNs in the flow near the substrate is presented.

Abstract
We assessed all 148 wetland nature reserves in China and the distribution of the four taxa of endemic and threatened terrestrial vertebrates, reptiles, amphibians, birds and mammals. Assessment of the wetland nature reserves was combined with the governmental list of the endemic and threatened vertebrates to identify the richness of the species. Species richness was scored as high, medium or low using a factor analysis method, and 31 wetland ecosystems were marked as high protection areas. The relationship between the threatened species and the endemic species in the reserves was also analyzed. We found that both richness patterns were similar. Based on the richness study, a nature reserve classification system with corresponding.

Abstract
Radiotherapy is advocated in the treatment of cancer of over 50 % of patients. It has long been considered as a focal treatment only. However, the observation of effects, such as fatigue and lymphopenia, suggests that systemic effects may also occur. The description of bystander and abscopal effects suggests that irradiated cells may exert an action on nearby or distant unirradiated cells, respectively. A third type of effect that involves feedback interactions between irradiated cells was more recently described (cohort effect). This new field of radiation therapy is yet poorly understood and the definitions suffer from a lack of reproducibility in part due to the variety of experimental models. The bystander effect might induce genomic instability in non-irradiated cells and is thus extensively studied for a potential risk of radiation-induced cancer. From a therapeutic perspective, reproducing an abscopal effect by using a synergy between ionizing radiation and immunomodulatory agents to elicit or boost anticancer immune responses is an interesting area of research. Many applications are being developed in particular in the field of hypofractionated stereotactic irradiation of metastatic disease.

Abstract
Data on 32 consecutive women with demonstrable urinary tract dysfunction for at least 6 months following radical hysterectomy (RH) for uterine cervical cancer, who received 24 sessions of extracorporeal magnetic innervation (ExMI) treatment twice-weekly were collected. The 1-h pad test weight decreased from 27.2 g pre-treatment to 12.1 g post-treatment (p < 0.05). Both the median UDI-6 and IIQ-7 scores showed statistically significant improvements (p < 0.001) at every stage of the ExMI treatment and in the 24.2 months mean follow-up duration after treatment. The symptoms of frequency, stress incontinence, urge incontinence and voiding difficulty showed statistically significant improvements (p < 0.001) after 8 and 24 sessions of ExMI treatment. The urodynamic parameters between pre-treatment and post-treatment after 24 sessions revealed no statistically significant changes. Based on the objective and subjective measures observed in this study, 24 sessions of twice-weekly ExMI treatment is an additional non-invasive therapy option for patients with the symptoms of lower urinary tract following RH.

Abstract
OBJECTIVES Cancer cells differ from normal body cells in their ability to divide indefinitely and to evade programmed cell death. Crosstalk between apoptosis and cell cycle processes promotes balance between proliferation and death, and limits population growth and survival of cells. However, intricate relationships between them and how they are able to manipulate the fate of cancer cells still remain to be clarified. Identification of key factors involved in both apoptosis and cell cycle regulation may help to address this problem. MATERIALS AND METHODS Identification of such key proteins was carried out, using a series of bioinformatics methods, such as network construction and key protein identification. RESULTS In this study, we computationally constructed human apoptotic/cell cycle-related protein-protein interactions (PPIs) networks from five experimentally supported protein interaction databases, and further integrated these high-throughput data sets into a Naïve Bayesian model to predict protein functional connections. On the basis of modified apoptotic/cell cycle related PPI networks, we calculated and ranked all protein members involved in apoptosis and cell cycle regulation. Our results not only identified some already known key proteins such as p53, Rb, Myc and Src but also found that the proteasome, Cullin family members, kinases and transcriptional repressors play important roles in regulating apoptosis and the cell cycle. Furthermore, we found that the top 100 proteins ranked by PeC were enriched in some pathways such as those of cancer, the proteasome, the cell cycle and Wnt signalling. CONCLUSIONS We constructed the global human apoptotic/cell cycle related PPI network based on five online databases, and a Naïve Bayesian model. In addition, we systematically identified apoptotic/cell cycle related key proteins in cancer cells. These findings may uncover intricate relationships between apoptosis and cell cycle processes and thus provide further new clues towards future anticancer drug discovery.

Abstract
To explore the expression changes of potential key genes and relevant biological processes in peripheral blood mononuclear cells of children with newly diagnosis of type 1 diabetes (T1D).Microarray data GSE9006 were downloaded from Gene Expression Omnibus (GEO) database, including peripheral blood mononuclear cells samples from 43 children with newly diagnosed T1D (NEW), 19 one-month (1-MO) follow-up samples, 19 4-month (4-MO) follow-up samples and 24 healthy controls. The differentially expressed genes (DEGs) were identified using Affy package in R, and cluster analysis of DEGs were performed following functional enrichment analysis with Database for Annotation, Visualization and Integrated Discovery (DAVID) and construction of protein-protein interaction (PPI) network with STRING database.We identified 73, 73, 96 DEGs in NEW group, 1-MO group and 4-MO group, respectively by comparing with healthy controls with |logFC|>0.58 and P-value<0.05. The cluster analysis of these DEGs showed that 4 genes, including human leukocyte antigen (HLA-DQA1), HLA-DRB4, integrin 3 (ITGB3) and killer cell lectin-like receptor subfamily F member 1 (KLRF1) were all significantly expressed in 3 groups, which were significantly enriched in asthma, T1D and intestinal immune network for IgA production pathway. And 57 genes enriched in cluster 5, which were only differentially expressed in NEW group, were involved in response to wounding, inflammatory response and blood coagulation as well as chemokine signaling pathway. Besides, the hub genes in PPI network of cluster 5 were identified, containing FOS, pro-platelet basic protein (PPBP), interleukin 8 (IL8), formyl peptide receptor-like 2 (FPR2) and platelet factor 4 (PF4).HLA-DQA1, HLA-DRB4, ITGB3 and KLRF1 might be targets for treatment of T1D, and 5 hub proteins, FOS, PPBP, IL8, FPR2 and PF4, were likely to be new markers for diagnosis of T1D.

Abstract
Pyrite (FeS2), being a promising material for future solar technologies, has so far exhibited in experiments an open-circuit voltage (OCV) of around 0.2 V, which is much lower than the frequently quoted 'accepted' value for the fundamental bandgap of ∼0.95 eV. Absorption experiments show large subgap absorption, commonly attributed to defects or structural disorder. However, computations using density functional theory with a semi-local functional predict that the bottom of the conduction band consists of a very low intensity sulfur p-band that may be easily overlooked in experiments because of the high intensity onset that appears 0.5 eV higher in energy. The intensity of absorption into the sulfur p-band is found to be of the same magnitude as contributions from defects and disorder. Our findings suggest the need to re-examine the value of the fundamental bandgap of pyrite presently in use in the literature. If the contribution from the p-band has so far been overlooked, the substantially lowered bandgap would partly explain the discrepancy with the OCV. Furthermore, we show that more states appear on the surface within the low energy sulfur p-band, which suggests a mechanism of thermalization into those states that would further prevent extracting electrons at higher energy levels through the surface. Finally, we speculate on whether misidentified states at the conduction band onset may be present in other materials.

Abstract
Spontaneous small-bowel hematomas most commonly involve the jejunum, followed by the ileum and duodenum, and occur in patients who receive excessive anticoagulation with phenprocoumon/warfarin or who have additional risk factors for bleeding. We report three cases of intramural small-bowel hematoma, all complications of treatment with phenprocoumon, which nowadays is used extensively for therapeutic and prophylactic purposes. Diagnosis can be readily attained by sonography and confirmed using computed tomography. Early diagnosis is crucial because most patients can be treated successfully without surgery. Based on this experience and data from the literature, conservative treatment is recommended for intramural intestinal hematomas, when other complications needing laparotomy have been excluded.

Abstract
This paper proposes a model for commonsense causal reasoning, based on the basic idea of neural networks. After an analysis of the advantages and limitations of existing accounts of causality, a fuzzy logic based formalism FEL is proposed that takes into account the inexactness and the cumulative evidentiality of commonsense causal reasoning, overcoming the limitations of existing accounts. Analyses concerning how FEL handles various aspects of commonsense causal reasoning are performed, in an abstract way. FEL can be implemented (naturally) in a neural (connectionist) network. This work also serves to link rule-based reasoning with neural network models, in that a rule-encoding scheme (FEL) is equated directly to a neural network model.

Abstract
BACKGROUND Inflammation-induced changes in smooth muscle may be the consequence of changes in the properties of smooth muscle itself, in the control by nerves and hormones, in the microenvironment, or in the balance of constitutive or induced mediators. A general concept is that the specific characteristics and effects of inflammation can be linked to the nature of the infiltrate and the associated mediators, which are dictated predominantly by the immune environment. Inflammatory mediators may regulate smooth muscle function by directly acting on smooth muscle cells or, indirectly, through stimulation of the release of mediators from other cells. In addition, smooth muscle is not a passive bystander during inflammation and our knowledge of molecular signaling pathways that control smooth muscle function, and the contribution of the immune mechanisms to smooth muscle homeostasis, has expanded greatly in the last decade. Recent studies also demonstrated the relevance of extracellular proteases, of endogenous or exogenous origin, redox imbalance, or epigenetic mechanisms, to gastrointestinal dismotility and inflammation in the context of functional and organic disorders. PURPOSE In this review we discuss the various types of inflammation and the established and emerging mechansims of inflammation-induced changes in smooth muscle morphology and function.

Abstract
WHAT IS KNOWN AND OBJECTIVE Invasive fungal infections are a major threat to renal transplant recipients. Micafungin and voriconazole are two useful antifungal agents for treating such infections. Our objective is to evaluate the comparative efficacy and safety of micafungin and voriconazole in the initial treatment of such infections. METHODS In this prospective, multicentre, open-labelled, randomized, controlled trial, renal transplant recipients with invasive fungal infections were assigned to receive either micafungin or voriconazole. The enrolled subjects received a kidney transplant between March 2008 and March 2010 at one of the two transplant centres in Henan Province, China. The efficacy and adverse effects of the two treatments were compared. RESULTS AND DISCUSSION The clinical trial enrolled 65 patients, of whom 31 were treated with micafungin, and 34 with voriconazole. The rates of microbiological evidence of infection in the micafungin and voriconazole groups were 64.5% and 70.5%, respectively, whereas the rates of Candida as the major cultured fungus were 80.0% and 75.0%, respectively. Complicated bacterial infection rates in the two treatment groups were 38.7% and 32.4%, respectively, whereas complicated CMV viral infection occurred at a rate of 19.2% and 23.5%, respectively. Fungal infection within one to 3 months after transplant was 83.6% (26/31) and 85.3% (29/34) in the micafungin and voriconazole groups, respectively. There was no significant difference between the two groups in terms of efficacy, survival beyond 10 days and discontinuation of treatment because of lack of efficacy (P > 0.05). Mortality rates in the micafungin and voriconazole groups were 9.7% (3/31) and 12.1% (4/33), respectively. Rates of adverse effects in the two groups were 41.9% and 51.6% (P > 0.05), respectively. WHAT IS NEW AND CONCLUSIONS This is the first comparison of micafungin and voriconazole in renal transplant patients. Our study shows that the effectiveness of micafungin was similar to that of voriconazole in such patients.

Abstract
Complete or partial thrombosis of the inferior vena cava is usually due to pre-existing malformation of the vessel, malignant tumors, ascending thrombosis, or thrombophilic disorders. We report the case of an 81-year-old woman, in whom a partial thrombosis of the vena cava was observed in the CT scan when re-staging was performed after six cycles of R-CHOP because of high-grade malignant non-Hodgkin lymphoma. Before chemotherapy was started, the patient had undergone an operation of the lumbar spine using cement augmentation. Retrospective analysis showed that cement had penetrated a segmental vein and spilled into the vena cava leading to formation of an adhering blood thrombus. The patient was free of symptoms and anticoagulation was started. Spillage of cement frequently occurs in the process of vertebroplasty and kyphoplasty and may result in serious sequelae. As these procedures are increasingly being used, physicians should be aware of these complications if a patient presents with thrombosis of the caval vein or signs of pulmonary embolism.

Abstract
Abstract
Background: Magnetic resonance imaging (MRI) is a valuable tool for assessing extent of breast cancer and monitoring treatment response. Quantitative measures by diffusion-weighted MRI (DWI) and dynamic contrast-enhanced (DCE) MRI reflect tumor cellularity and vascularity. Tumor grade and some histopathological markers, such as ER, PR, HER-2, Ki67 and P53, are prognostic factors that can also be associated with tumor cellularity and vascularity. DWI and DCE measures may therefore provide a noninvasive means for predicting disease prognosis and stratifying patients to appropriate therapies. The purpose of this study was to investigate the correlation between quantitative MRI features and prognostic pathological factors in patients with invasive breast cancer.
Methods: This IRB-approved retrospective study included patients with biopsy-proven invasive cancer who underwent 1.5T breast MRI (including DCE and DWI) from October 2005 to May 2006 prior to treatment. Pathology data was obtained from pre-treatment biopsy and intrinsic subtype classification was approximated by standard immunohistochemistry characteristics. After excluding cases with missing MRI or pathology data, the final study cohort included 41 invasive cancers (36 ductal and 5 lobular carcinomas) in 36 patients. MRI measures included lesion DCE kinetic features: peak initial enhancement (PE), percent rapid enhancement (RE), and percent washout (WO), and DWI normalized apparent diffusion coefficient values (nADC). Associations between imaging features and pathology markers, cancer grades and intrinsic subtypes were evaluated by Mann-Whitney U test and multivariate logistic regression.
Results: Results of univariate comparisons are summarized in Table 1. One or more DCE-MRI kinetic parameters were significantly predictive (p<0.05) of each of the histopathological markers with the exception of ER, which was marginally associated with WO (p=0.05). Each of the DCE kinetics parameters significantly discriminated grade III tumors from grades I and II and luminal A from luminal B and basal-like intrinsic subtypes. In multivariate regression, both PE and WO were significant independent predictors of tumor grade (p=0.0094, p=0.0005, respectively). WO and nADC were significant independent predictors of PR status (p=0.0054, p=0.0027), while PE was the only significant independent predictor of both Ki67 (p=0.014) and intrinsic subtype (p=0.015).
Conclusion: This preliminary study suggests that quantitative MRI measures are associated with prognostic tumor markers and may provide valuable noninvasive characterization of tumor biology. Larger prospective studies are needed to validate our findings.

Abstract
A novel lift-off method has been developed for fabricating patterned W(18)O(49) nanowires in vertical arrays and on a large scale. These W(18)O(49) nanowire arrays have an average diameter of about 30 nm, and their lengths range from 2-3 μm. In every pattern of a 2 inch sample, the nanowires exhibit the same morphology and growth density. They are single crystals with monoclinic structure and grow along the [010] direction. Field emission (FE) measurements show that they have a turn-on field of 6.2 V μm(-1) and their emission current density can reach 500 μA cm(-2) at an electric field of 10.9 V μm(-1). Because the W(18)O(49) nanowire patterns synthesized by this simple method still have good FE performance, comparable to many cathode nanostructures with excellent FE properties, it suggests that it may provide an effective and simple preparation technique for patterned growth of nanowire arrays in future FE applications.
