Abstract
We report the NMR observation of a skewed distribution of ^{17}O Knight shifts when a magnetic field quenches superconductivity and induces long-range charge-density-wave (CDW) order in YBa_{2}Cu_{3}O_{y}. This distribution is explained by an inhomogeneous pattern of the local density of states N(E_{F}) arising from quasiparticle scattering off, yet unidentified, defects in the CDW state. We argue that the effect is most likely related to the formation of quasiparticle bound states, as is known to occur, under specific circumstances, in some metals and superconductors (but not in the CDW state, in general, except for very few cases in 1D materials). These observations should provide insight into the microscopic nature of the CDW, especially regarding the reconstructed band structure and the sensitivity to disorder.

Abstract
AIMS To evaluate the sampling adequacy and diagnostic accuracy of the endometrial SAP-l sampling device in detecting endometrial lesions based on histopathological examination. MATERIALS AND METHODS In total, 182 patients who required an endometrial biopsy were enrolled in this study. All of the patients underwent endometrial biopsies with the SAP-l sampler prior to hysteroscopy (169/182) or dilatation and curettage (D&C) (13/182). Endometrial tissues were obtained at biopsy for histopathological examination. RESULTS Ad- equate endometrial specimens were obtained in 148 of 182 patients (81.32%). Menopause (p = 0.000), endometrial thickness (p = 0.004), and the types of endometrial diseases (p = 0.009) differed significantly between the two groups. Among the 169 patients who underwent hysteroscopy, sampling scratches were observed in the uterine cavity in 147 cases (86.98%). Compared to traditional methods, such as hysteroscopy and D&C, the sampling diagnostic sensitivity, specificity, and positive and negative predictive values were 82.35%, 100%, 100% , and 97.76% for endometrial carcinoma (n=17) and 37.5%, 100%, 100% and 97.76% for endometrial atypical hyperplasia (n=8), respectively. Those that were misdiagnosed occurred because the lesions were focal or localized in a small part of the uterine cavity. The sampling diagnostic sensitivity for polyps (n=32) was 12.5%. Two patients with submucosal leiomyoma went undiagnosed based on the sample specimens. CONCLUSION Endometrial sampling using the SAP-l sampler is a minimally invasive altemative technique for obtaining adequate endometrial specimens for histopathological examination. The SAP-l sampler was useful in detecting endometrial carcinoma and atypical hyperplasia cases that were not highly suspected to be localized; however, this method was not useful in detecting endometrial polyps and submucosal leiomyomas.

Abstract
Phase II of seed imbibition is a critical process during seed priming. To identify genes involved in rice seed priming, the altered proteins between the dry and imbibed (24 h) seeds were compared using a two-dimensional gel electrophoresis system in this study. Ten significantly changed proteins (fold change ≥ twofold; P < 0.01) were successfully identified, which could be categorised as carbohydrate and protein biosynthesis and metabolism-related, signalling-related, storage and stress-related proteins. A meta-analysis indicated that the highest expression of the identified genes was at the milk and dough stages and in the endosperm tissue. Quantitative real-time PCR analysis showed that there was significant variation in gene expression (except FAD-dependent oxidoreductase) in embryos during seed priming (0-48 h). The expression of genes associated with stress appeared at the early imbibition stage, while those associated with carbohydrate metabolism, protein synthesis and signalling increased at the late imbibition stage. Three identified proteins (glucose-1-phosphate adenylyltransferase large subunit, aminotransferase and prolamin precursor) had similar transcript and protein expression patterns in embryos. Based on phenotype and gene expression, the optimal stop time for seed priming is 24 h, when these three genes have relatively low expression, followed by significant induction during imbibition in embryos. These three genes are ideal candidate biomarkers for rice seed priming.

Abstract
Objective: To prepare a rabbit monoclonal antibody GCET2 and to investigate its diagnostic value in the workup of diffuse large B-cell lymphoma (DLBCL). Methods: GCET2 rabbit monoclonal antibody was developed by using RabMAb® technology, and its specificity was confirmed by ELISA, Western blot, immunohistochemistry (IHC) and flow cytometry. A panel of immunomarkers including GCET2, CD10, bcl-6, MUM1, GCET1, FOXP1, Ki-67 and CMYC was evaluated in 81 cases of DLBCLs, 5 cases of follicular lymphomas (FL) and 2 cases of Burkitt's lymphomas. Results: Rabbit monoclonal GCET2 antibody (clone EP316) was developed with specificity for normal germinal center B-cells (GCB) and GCB origined lymphomas. In 81 cases of DLBCL, the positive rate of GCET2 was 43.2%(35/81), which was significantly higher than that of other germinal center markers. Moreover, among 81 DLBCLs, the proportions of high CMYC expression in GCET2 negative and positive groups were 15.2% (7/46) and 2.8% (1/35), respectively. Conclusion: GCET2 is a sensitive immunohistochemical marker for GCB derived lymphomas. Combined with other biomarkers, it may improve the diagnostic sensitivity of GCB-DLBCL.

Abstract
Objective: To analyze the clinical features of one case of spontaneous hemothorax caused by primary pleural chondrosarcoma and therefore to improve the understanding of this disease. Methods: The clinical features of a case with primary pleural chondrosarcoma were analyzed retrospectively and the related literatures were reviewed.The literature review was carried out with "primary pleural, chondrosarcoma" in Chinese and English respectively, as the search terms in Wanfang Data, CNKI and PubMed database from January 1980 to October 2015. A total of 6 articales, 1 in Chinese and 5 in English, were reviewed. Results: A 29 year-old male patient was admitted to the hospital because of fever, chest tightness, shortness of breath for 20 days. CT scan of the chest showed a mass near the right posterior fourth rib and right pleural effusion.Routine examination of the pleural effusion confirmed the presence of hemothorax. Thoracotomy was performed and revealed hemothorax in the right thorax, and a mass near the pleural apex. The tumor was removed by surgery and pleural decortication was also performed. Pathology study confirmed the diagnosis of high-differentiated chondrosarcoma. The patient was followed and there was no recurrence until now. A total of 6 case reports were retrieved from Wanfang Data, CNKI and PubMed. Five cases had complete data, including 2 males and 3 females(age from 28 to70), and another (a 78-year old male) without adequate data. Conclusions: Primary pleural chondrosarcoma is a rare disease, and hemothorax as the first manifestation is even rare. It is easily to be misdiagnosed due to nonspecific clinical symptoms.The final diagnosis depends ultimately on pathological biopsy. Thoracotomy is the most effective method for treatment of primary pleural chondrosarcoma.

Abstract
During development of the nervous system, molecular signals mediating cell-cell interactions play critical roles in the guidance of axonal growth and establishment of synaptic functions. The Eph family of tyrosine kinase receptors and their ephrin ligands has been shown to mediate neuronal interactions in the development of topographic axon projection maps in several brain regions, and the loss of Eph activities result in defects in select axonal pathways. However, effects of deficiencies of the Eph signals on animal behavior have not been well documented. In this study, we showed that inactivation of a ligand of the Eph receptors, ephrin-A5, resulted in defects in maternal behavior and alterations in anxiety. Female ephrin-A5 -/- mice show significant defects in nest building and pup retrieval. In addition, lower levels of anxiety were observed in both male and female null mice. These changes were not due to deficiencies in estradiol, progesterone or corticosterone levels. Our observations suggest that ephrin-A5 plays a key role in the development and/or function of neural pathways mediating mouse maternal care and anxiety.

Abstract
OBJECTIVE To determine whether color doppler ultrasonography (CDU), thyroid function or thyroid autoimmune antibodies could identify Graves' disease in pregnancy(GDP) in pregnant patients with newly diagnosed thyrotoxicosis. METHODS It is an observational study. Sixty-eight pregnant patients with newly diagnosed thyrotoxicosis including gestational hyperthyroidism(GHT) subjects (GHT group, n=33) and GDP subjects (GDP group, n=35), and 62 age-and sex-matched healthy subjects (C1 group: pregnant, n=32, C2 group: non-pregnant, n=30) were recruited. Thyroid function, human chorionic gonadotropin(HCG), thyroid autoimmune antibodies were detected. Peak systolic velocity of the superior thyroid artery (STA-PSV) and diastole inner diameter(STA-D) of the superior thyroid artery were measured by CDU. A ROC curve was used to evaluate STA-PSV, STA-D, thyroid function and thyroid autoimmune antibodies for identification of GDP. RESULTS The area under the ROC curve of STA-PSV, STA-D and thyroid stimulating hormone (TSH), free T4 (FT4) for GDP were 0.905, 0.887, 0.803 and 0.786, respectively. The optimal cut-off points of STA-PSV, STA-D, TSH and FT4 for GDP were 40 cm/s, 2.0mm, 0.03 mIU/L and 30 pmol/L with the sensitivity of 82.9%, 72.1%, 81.8%, 76.2% and specificity of 81.8%, 87.9%, 75.2%, 80.3%, respectively. CONCLUSIONS Detection of STA-PSV and STA-D by CDU, as well as thyroid function, is useful in screening GDP in pregnant patients with thyrotoxicosis.

Abstract
The "classical" EAU model induced by immunization of mice with the retinal protein IRBP or its peptides has been very useful to study basic mechanisms of ocular inflammation, but is inadequate for some types of studies due to the need for active immunization in the context of strong bacterial adjuvants. We generated transgenic (Tg) mice on the B10.RIII background that express a T cell receptor (TCR) specific for IRBP161-180. Three strains of TCR Tg mice were established. Spontaneous uveitis developed in two of the three strains by 2-3 months of age. Susceptibility correlated with a higher copy number of the transgenic TCR and a higher proportion of TCR Tg T cells in the peripheral repertoire. Even in mice with uveitis, peripheral IRBP-specific CD4(+) T cells displayed mostly a naïve phenotype. In contrast, T cells infiltrating uveitic eyes mostly showed an effector/memory phenotype, and included Th1, Th17 as well as T regulatory cells. These mice thus provide a new and distinct model of uveitis from the "classical" EAU, and may represent some types of uveitis more faithfully. Importantly, this new transgenic model of uveitis can serve as a template for therapeutic manipulations, and as a source of naïve retina-specific T cells for a variety of basic and pre-clinical studies. Several examples of such studies will be discussed.

Abstract
The oncogene Lysosome-associated protein transmembrane-4β (LAPTM4B) gene was identified, and the polymorphism region in the 5′-UTR of this gene was certified to be associated with tumor susceptibility. LAPTM4B-35 protein was found to be highly expressed in various solid tumors and could be a poor prognosis marker. The functions of LAPTM4B in solid tumors were also explored. It is suggested that LAPTM4B could promote the proliferation of tumor cells, boost invasion and metastasis, resist apoptosis, initiate autophagy and assist drug resistance.

Abstract
To evaluate stearoyl-CoA desaturase (SCD), hormone-sensitive lipase (HSL), lipoprotein lipase (LPL), and peroxisome proliferator-activated receptor (PPARγ) expression in Lanzhou fat-tailed sheep (with and without docked tails), 18 rams were randomly divided into two equal groups (docked group, LT; control group, LC). These data were also used to increase the understanding of sheep fat deposition and metabolism. All animals were harvested at the age of 18 months, and expression was determined for 10 tissues. The results indicated that the fat weight of each tissue in LT was higher than in LC (P < 0.05). SCD expression in semitendinosus, omentum majus fat (OF), subcutaneous fat, kidney fat (KF), and subcutaneous rump fat was higher in LT than in LC rams (P < 0.05). Trends (P < 0.10) associated with higher HSL expression of LC in comparison to that of LT rams in intestinal fat, OF, and KF tissues were detected. Numerically, LPL expression was the highest in KF, OF, and kidney tissues, but there were few differences (P > 0.10). PPARγexpression was greater in LT than in LC rams in liver tissues (P < 0.05), but there were few differences in other tissues. No significant differences were found with regard to the regression analysis of expression and adipose tissue weights, but the two indices exhibited the same trend. The results indicated that changes in fatty deposits may be due to the common control of docking management and the minor effects associated with the regulation of SCD, HSL, LPL, and PPARγexpression.

Abstract
Abstract
Background: Breast cancer (BC) remains the second leading cause of cancer-related deaths for women in the United States and is recognized to be a heterogeneous disease. Advances in technologies such as whole genome sequencing are leading the way to precision medicine and the leading researchers are envisioning personalized therapies in the not too distant future. However, given the diversity of cancer cell populations, that remains a challenging task at best. The tumor form of MUC1 (designated tMUC1), a transmembrane glycoprotein, is aberrantly glycosylated and overexpressed in ∼95% of BC. We have developed an antibody (TAB004) that specifically recognizes tMUC1 across all major subtypes of BC and importantly does not recognize normal breast epithelia. This is a significant development in light of the challenges faced in treating triple negative BC.
Methods: A panel of thirty BC cell lines was obtained from ATCC. The following techniques were used to assess the specificity of TAB 004 to the major subtypes based on ER, PR and Her2 expression: 1) Flow cytometry to quantify membrane bound expression of tMUC1 using Cy7-conjugated TAB004; 2) Western blotting to detect molecular weight patterns of tMUC1 in whole cell lysate; 3) A TAB004 based GMP-grade ELISA kit to measure shed tMUC1 in the supernatant and 4) In vivo imaging of tumors in mice using TAB 004 conjugated to Indocyanine Green (ICG). Specificity and sensitivity was further confirmed using primary human serum and tissue samples from all major BC subtypes obtained from bio-repositories at Duke University Cancer Center, Fox Chase Cancer Center and Carolinas Health Care System. Shed tMUC1 in serum samples were tested using the TAB 004 ELISA kit and tissue sections were analyzed using immunohistochemical (IHC) staining with TAB 004 conjugated to HRP.
Results: 1) Flow cytometry data shows that TAB 004 recognized tMUC1 on all major BC subtypes: 25 out of 30 BC cell lines tested had higher expression than a normal epithelial breast cell line; 2) Western blotting also detected tMUC1 on all BC subtypes with distinct molecular weight patterns; 3) ELISA showed high levels of shed tMUC1 by most BC cells and correlated with bound/cytoplasmic levels. 4) In vivo imaging shows clear localization of TAB004-ICG to the tumors expressing tMUC1. Primary human breast cancer patient data shows that shed tMUC1 was detected in the serum obtained from all major BC subtypes and showed statistically significant differentiation from normal/benign. IHC results show strong tMUC1 expression in malignant tissue with excellent differentiation from adjacent normal tissue.
Conclusion: TAB004 antibody's extraordinary specificity across major BC subtypes has been confirmed with flow cytometry, western blotting, ELISA and Immunohistochemistry. A number of clinical applications are under development: (a) An ELISA test as a supplement to mammography for the early detection of BC in women with dense breasts; (b) serum monitoring during treatment and to detect disease recurrence; and, (c) targeted antibody-drug/antibody-imaging agent based therapies and imaging modalities particularly for triple negative BC.

Abstract
Pd/CeO2-ZrO2-Nd2O3 (CZN) catalysts with different CeO2/ZrO2 molar ratios were synthesized and have been characterized by multiple techniques, e.g. XRD in combination with Rietveld refinement, UV-Raman, XPS and in situ DRIFTS. The XRD pattern of CZN with CeO2/ZrO2 molar ratios ≥1/2 can be indexed satisfactorily to the fluorite structure with a space group Fm3̄m, while the XRD patterns of CZ12 only display diffraction peaks of the tetragonal phase (S.G. P42/nmc). Nd addition can effectively stabilize the cubic structure of the CZN support and increase the enrichment of defect sites on the surface, which may be related to the better catalytic activity of Pd/CZN12 catalysts compared with Pd/CZ12. The presence of moderate ZrO2 can increase the concentration of O* active species, leading to accelerate the formation of nitrate species and thus enhance the catalytic activity of NOx and HC elimination. The Pd-dispersion decreases with the increasing Zr content, leading to the decreased CO catalytic activity, especially for the aged catalysts. The change regularity of the OSC value is almost the same with the in situ dynamic operational window, demonstrating that the in situ dynamic operational window is basically affected by the OSC value.

Abstract
Spermatogonial stem cells (SSC) are unique adult stem cells that reside within the seminiferous tubules of the testis. As stem cells, SSC maintain the ability to self-replicate, providing a potentially unlimited supply of cells and an alternate source for preservation of the male genome. While self-renewing, long-term SSC culture has been achieved in mice, there is virtually no information regarding culture requirements of felid SSC. Therefore, the objectives of this study were to (1) evaluate the ability of 3 feeder cell lines to support germ cell colony establishment in domestic cats (Felis catus), and (2) assess long-term culture using the best feeder(s). Cells isolated enzymatically from peripubertal cat testes (n = 4) and enriched by differential plating were cultured on mouse embryonic fibroblasts (STO line), mouse-derived C166 endothelial cells, and primary cat fetal fibroblasts (cFF). Colony morphology was assessed every other day and immunocytochemistry (ICC) was performed to investigate expression of SSC markers. At 5 days in vitro (DIV), a cluster forming activity assay was used to estimate the number of SSC supported by each feeder cell line. Differences among treatments were compared using Tukey-Kramer adjustment for pair-wise mean comparisons. Data were expressed as mean cluster number ± SE per 105 cells input. When cultured on STO feeders, cat germ cells were distributed as individual cells. On both C166 cells and cFF feeders, germ cell clumps (morphologically consistent with SSC colonies in other species) were observed. Immunocytochemistry revealed that the single germ cells present on STO feeders were positive for UCHL1 and weakly expressed PLZF and OCT4. Cells within the germ cell clumps on C166 cells and cFF co-expressed all 3 SSC markers. The C166 cells supported a higher number of germ cell clusters (77.4 ± 13.8) compared with STO (3.5 ± 1.1, P = 0.0003) or cFF (22.7 ± 1.0, P = 0.0024). Therefore, subsequent subculture experiments were performed exclusively with C166 feeder layers. Cultures from 2 donors were passaged at 12 DIV and periodically as needed thereafter. Germ cell clumps consistently reestablished following each subculture and immunocytochemistry analysis confirmed maintenance of all 3 SSC markers. Cells were also positive for alkaline phosphatase activity. Cells that had been cryopreserved in culture medium with 5% (vol/vol) dimethyl sulphoxide after144 DIV (7 passages) were thawed and cultured for an additional 18 days. These cells continued to express SSC markers and form germ cell clusters. Taken together, these data demonstrate that C166 feeder cells can facilitate colony establishment and in vitro propagation of germ cell clumps in the domestic cat. This represents an important first step towards attainment and optimization of a long-term SSC culture system in the cat. This system would provide a mechanism to explore regulation of spermatogenesis, test species-specific drugs, and produce transgenic biomedical models.

Abstract
In the current study, morphological traits and molecular markers were used to assess the genetic diversity of 29 cultivated tomatoes, 14 wild tomatoes and seven introgression lines. The three components of the principal component analysis (PCA) explained 78.54% of the total morphological variation in the 50 tomato genotypes assessed. Based on these morphological traits, a three-dimensional PCA plot separated the 50 genotypes into distinct groups, and a dendrogram divided them into six clusters. Fifteen polymorphic genomic simple- sequence repeat (genomic-SSR) and 13 polymorphic expressed sequence tag-derived SSR (EST-SSR) markers amplified 1115 and 780 clear fragments, respectively. Genomic-SSRs detected a total of 64 alleles, with a mean of 4 alleles per primer, while EST-SSRs detected 52 alleles, with a mean of 4 alleles per primer. The polymorphism information content was slightly higher in genomic-SSRs (0.49) than in EST-SSRs (0.45). The mean similarity coefficient among the wild tomatoes was lower than the mean similarity coefficient among the cultivated tomatoes. The dendrogram based on genetic distance divided the 50 tomato genotypes into eight clusters. The Mantel test between genomic-SSR and EST-SSR matrices revealed a good correlation, whereas the morphological matrices and the molecular matrices were weakly correlated. We confirm the applicability of EST-SSRs in analyzing genetic diversity among cultivated and wild tomatoes. High variability of the 50 tomato genotypes was observed at the morphological and molecular level, indicating valuable tomato germplasm, especially in the wild tomatoes, which could be used for further genetic studies.

Abstract
In order to study genetic variability and develop better strategies for the utilization of 48 tomato cultivars from America, China, the Netherlands, and Portugal, genomic simple sequence repeat (gSSR) and EST-derived SSR (EST-SSR) markers were applied. In all, 15 of 82 gSSR and 18 of 115 EST-SSR markers showed polymorphic loci. There were 995 and 2072 clear fragments amplified by polymorphic gSSR and EST-SSR markers, respectively. The total and average number of alleles detected by EST-SSRs (75, 4.2) was more than gSSRs (54, 3.6) as a result of some multi-locus EST-SSRs. A lower polymorphism information content value was found in gSSRs (0.529) compared to EST-SSRs (0.620). Similarity coefficient matrixes of the 48 tomato cultivars were established based on the gSSRs and EST-SSRs, and UPGMA dendrograms were constructed from the gSSRs and EST-SSRs similarity coefficient matrixes. A high similarity was observed between the gSSRs and EST-SSRs dendrograms. Genetic variability of four tomato populations from different countries showed that the observed number of alleles and Nei's genetic diversity were highest in the American population, and the effective number of alleles was highest in the Dutch population. The estimated genetic structure showed some tomato cultivars from different countries shared a common genetic background, which might be related to gene flow. It was inferred that both gSSR and EST-SSR markers were effective to assess genetic variability of tomato cultivars, and the combination of both markers could be more effective for genetic diversity analysis in tomato.

Abstract
Cultivar identification diagrams (CIDs) provide a rapid and efficient approach for identifying cultivars based on random amplified polymorphic DNA (RAPD) markers. In this paper, 64 tomato cultivars were identified using a CID. Using RAPD profiles, clustering analysis was performed to analyze genetic diversity. The results showed that 8 RAPD primers could completely separate the 64 cultivars according to the obtained polymorphic bands; a CID of the 64 tomato cultivars was then constructed. As verification of the CID validity, 8 randomly selected cultivars were investigated and proven to be well distinguished. In addition, 33 DNA bands were obtained, 20 (60.6%) of which were polymorphic. Genetic distances were calculated with a range of 0.032 to 1.402. Clustering analysis showed that the 64 tomato cultivars were divided into 4 groups with a similarity coefficient of 0.40. Using this novel strategy, with the same RAPD data, both CID and clustering analysis can simultaneously determine tomato cultivars and their genetic diversity.

Abstract
In this study, we investigated the prognostic factors of infantile rotavirus (RV) infection. A total of 102 infants with RV enteritis were divided into 2 groups according to the standards of improvement and cure at the time of discharge from the hospital: improvement group (N = 58; 47 males and 11 females with an average age of 15.19 ± 5.03 months) and the cure group (N = 44; 34 males and 10 females with an average age of 10.02 ± 4.92 months). Both groups were phlebotomized for the detection of serum glutamic oxaloacetic aminotransferase, creatine kinase-MB, and lactate dehydrogenase. Prognostic factors and clinical data were analyzed by univariate and multivariate logistic analysis. Among the 102 cases of RV infection, 58 were cured and 44 were improved. Univariate analysis showed that the 2 groups were significantly different in age, feeding pattern, concentrations of serum glutamic oxaloacetic aminotransferase, creatine kinase-MB, and lactate dehydrogenase, and central nervous system damage. Logistic regression analysis showed that age, feeding, and central nervous system damage were significant independent prognostic factors for RV enteritis (P < 0.05). There were no statistical differences in gender, course of disease, and respiratory infection (P < 0.05). Both myocardial and hepatic damages presented a temporary feature in the infants and had no significant influence on prognosis. Age, feeding pattern, and central nervous system damage are significant independent prognostic factors for RV infection. These factors should be carefully considered in clinical practice.

Abstract
AIM This retrospective study aimed to evaluate the suitability of retroperitoneal laparoscopic ureterolithotomy (RPLU) in the treatment of complex proximal ureteral calculi. METHODS Included were 24 patients who underwent RPLU for complex proximal ureteral stones from November 2008 to June 2010. RESULTS A retroperitoneal approach was performed in 23 patients with a mean operative time of 79.6 min (range of 65-130 min) and mean intraoperative blood loss of 20.1 mL (10-50 mL). No postoperative complications were encountered within during the follow-up period of 9.1 months (3-22 months). Only one patient who underwent RPLU within one week of failed ESWL was converted to open surgery due to severe adhesions around ureter and the injury of aberrant renal artery at the lower pole of left kidney encountered during the RPLU. CONCLUSION RPLU is safe and effective in the treatment of complex upper ureteral stones and can become a first-line surgical management of the disease.

Abstract
A green and facile approach to produce graphene using an environmentally friendly reagent, namely proanthocyanidin (PC) as a reducing agent was developed. The obtained graphene (PC-rGO) was characterized using Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis and X-ray photoelectron spectroscopy, confirming the effective reduction of GO. With the incorporation of PC-rGO into natural rubber (NR) latex, NR/PC-rGO composites were then prepared by an ultrasonically assisted latex mixing and the co-coagulation. The results show that PC-rGO presents a good dispersion and exfoliation in the NR matrix, contributing to an increase in the mechanical performance. Compared with neat NR, the tensile strength, modulus at 300%, and tear strength for NR composites containing 0.9 phr PC-rGO were increased by 50.2%, 154.9% and 65.2%, respectively. With increasing PC-rGO loading, cross-link density and storage modulus of NR composites increase because of the formation of cross-link points and physical interaction between PC-rGO and the matrix.

Abstract
Extracorporeal membrane oxygenation (ECMO) may offer life-saving treatment in severe pulmonary contusion or acute respiratory distress syndrome when conventional treatments have failed. However, because of the bleeding risk of systemic anticoagulation, ECMO should be performed only as a last resort in multiple trauma victims. Here, we report ECMO as a bridge for right main bronchus reconstruction and recovery of traumatic wet lung in a 31-year-old male multi-trauma patient with right main bronchial disruption, bilateral pulmonary contusion, cerebral contusion and long bone fracture. The patient was discharged without any obvious complication. ECMO support in a traumatic brain injured patient with severe hypoxemia caused by lung contusion and/or tracheal bronchus disruption is not an absolute contraindication.

Abstract
Formononetin is a naturally existing isoflavone, which can be found in the roots of Astragalus membranaceus, Trifolium pratense, Glycyrrhiza glabra, and Pueraria lobata. It was found to be associated with inhibition of cell proliferation and cell cycle progression, as well as induction of apoptosis in various cancer cell lines. However, the effect of formononetin on breast cancer cell metastasis remains unclear. In this study, we examined the effect of formononetin on the migration and invasion of breast cancer cells MDA-MB-231 and 4T1 in vitro and in vivo. Our data demonstrated that formononetin did not effectively inhibit the cell viability of MDA-MB-231 and 4T1 in 24 h with the concentration lower than 160 μmol/l. When treated with nontoxic concentration of formononetin, the migration and invasion of MDA-MB-231 and 4T1 cells were markedly suppressed by wound healing assay, chamber invasion assay, and in vivo mouse metastasis model. In vitro, formononetin reduced the expression of matrix metalloproteinase-2 (MMP-2), MMP-9 and increased the expression of tissue inhibitor of metalloproteinase-1 (TIMP-1) and TIMP-2. Furthermore, the immunofluorescence and immunoblotting assays indicated that formononetin was very effective in suppressing the phosphorylation of Akt and PI3K. Collectively, these results suggest that formononetin inhibited breast cancer cell migration and invasion by reducing the expression of MMP-2 and MMP-9 through the PI3K/AKT signaling pathway. These findings demonstrate a potentially new therapeutic strategy of formononetin as anti-invasive agent for breast cancer.

Abstract
Microglia, the primary immune cells in the brain, have been implicated as the predominant cells governing inflammation-mediated neuronal damage. In response to immunological challenges such as lipopolysaccharide (LPS), microglia are activated and subsequently inflammatory process is initiated as evidenced by the release of pro-inflammatory chemokines and cytokines. Here we show that Group I metabotropic glutamate receptor 5 (mGluR5) is involved in LPS-induced microglia activation. LPS triggered a similar pattern of [Ca2+]i oscillation in N9, Toll-like receptor 4 (TLR4)-mutant EOC 20, TLR4-wild-type and TLR4-deficient primary mouse microglia, suggesting that LPS-induced [Ca2+]i oscillation is independent of TLR4. The characteristics of [Ca2+]i oscillation induced by LPS are consistent with those observed in mGluR5 activation. In addition, mGluR5 antagonist 3-[(2-methyl-1,3-thiazol-4-yl)ethynyl]pyridine (MTEP) abolished LPS-induced [Ca2+]i oscillation. Immunocytochemistry demonstrated that LPS colocalizes with mGluR5 in microglia and the direct binding of LPS and mGluR5 was further validated by antibody-based fluorescence resonance energy transfer (FRET) technology. Activation of mGluR5 using a selective agonist (RS)-2-chloro-5-hydroxyphenylglycine (CHPG) significantly expanded LPS-induced nuclear factor-kappa B (NF-κB) activity and CHPG alone increased NF-κB activity as well. But, mGluR5 antagonist MTEP attenuated the actions of LPS, CHPG and the additive effect of LPS and CHPG in microglia. LPS induced tumor necrosis factor-α (TNF-α) secretion in N9 microglia, but not in TLR4-mutant EOC 20 and TLR4-deficient primary mouse microglia. CHPG reduced LPS-caused TNF-α production, but MTEP increased LPS-induced TNF-α production and blocked the effect of CHPG in N9 microglia. These data demonstrate that mGluR5 and TLR4 are two critical receptors that mediate microglia activation in response to LPS, suggesting that mGluR5 may represent a novel target for modulating microglia-dependent neuroinflammation.

Abstract
The toxic effects of x-ray radiation on eye development was measured using zebrafish as a model organism. Zebrafish embryos at 8 h post-fertilization (hpf) were irradiated using X-rays at doses of 1, 2, 4, and 8 Gy. At 24 and 48 hpf, x-ray radiation induced a significant increase in reactive oxygen species (ROS) content and cell apoptotic signals. Both of these increases were dose dependent and there were significant positive relationships between them at 24 hpf. At 48 and 72 hpf, the increase of ROS concentration can be eliminated by increasing activities of superoxide dismutase and catalase. Although the ROS generated by x-ray radiation caused a significant increase in cell apoptosis at 24 and 48 hpf, the cellular layers of the retina and lens formation in the irradiated groups were not significantly disrupted at 144 hpf compared with the control group, with the exception of a heterogeneous distribution of the cells in inner nuclear cell layer and a significant decrease in the diameters of whole eyes after 8 Gy irradiation. X-Ray radiation at later stages of gastrulation may not cause distinct optic complications; however, there is still a risk of microophthalmia at high doses of irradiation.

Abstract
BACKGROUND Despite progress of medical, the fast and accurate diagnosis of tuberculous pleuritis (TP) continues to be a challenge, mainly because of the lack of specific clinical features and the difficulty in isolating the Mycobacterium tuberculosis. OBJECTIVES To investigate the role of medical thoracoscopy in definite diagnosis of tuberculous pleuritis, especially the feature of visual diagnosis in tuberculous pleuritis via medical thoracoscopy. We performed a retrospective review of the utility of medical thoracoscopy in tuberculous pleuritis. PATIENTS AND METHODS A retrospective chart review was performed of 91 patients who had medical thoracoscopy for suspected TP at the Second Xiangya Hospital from October 1, 2006 to July 30, 2012. RESULTS In ninety one cases, 76 patients were diagnosed with TP by pathologic diagnosis. The visual findings via thoracoscopy of 76 TP patients included the following: (1) necrosis (76.32%, n=58), (2) diffuse miliary nodules (64.67%, n=49), (3) single or multiple pleural nodules (14.47%, n=11), (4) hyperemic, edematous and thickened pleura (56.58%, n=43), and (5) pleural adhesions or fibrotic septa (78.95%, n=60), and all of these samples had hydrothorax or loculated effusion. The diagnostic efficiency of visual diagnosis via medical thoracoscopy about tuberculous pleuritis was 93.41%. In the non-invasive test, ADA > 40 u/l with LDH > 200 u/l for TP showed relatively high sensitivity and specificity (73.68%, 80.00%, respectively). CONCLUSIONS TP presents a variety of scopic phenotypes under medical thoracoscopy. The experienced pulmonologists visually diagnose TP efficiently and directly via medical thoracoscopy. Medical thoracoscopy with combined biopsy is an accurate and safe method for diagnosing TP.

METHODS Clinical and pathological data on 73 cases of male breast carcinoma were collected and microscopic pathological features were examined. Immunostaining for ER, PR, HER2, Ki-67, CK5/6, EGFR, GCDFP15, MGB, AR and FOXP1 was performed and the molecular subtype was classified.
RESULTS Invasive carcinoma of no special type was the major histological type in our study group (71.2%, 52/73). Except for 4 cases of carcinoma in situ, forty-two male invasive carcinomas (42/69, 60.9%) were classified as luminal A subtype while 24 cases (24/69, 34.8%) were classified as luminal B subtype. Only 2 cases of basal-like subtype and 1 case of HER2 positive subtype were identified in this group. Nuclear immunostaining of AR and FOXP1 could be observed in 82.4% (48/57) and 71.9% (41/57) of the cases respectively. Cases of luminal A subtype expressed GCDFP15 (73.5%, 25/34) and MGB (58.8%, 20/34) more frequently than those of luminal B subtype (34.8%, 8/23 and 43.5%, 10/23, respectively).
CONCLUSIONS Invasive carcinoma of no special type was the most common histological type in male breast carcinoma. Our study revealed that luminal A and B subtypes were the major types of male breast carcinoma. AR and FOXP1 were highly expressed in male breast cancer. Luminal A subtype tends to express GCDFP15 and MGB more frequently than luminal B subtype.

[PMID: 23489438 DOI: 10.1111/dom.12096] [Citation(s) in RCA: 37] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2012] [Revised: 11/04/2012] [Accepted: 03/05/2013] [Indexed: 11/29/2022]
Abstract
AIMS To determine whether baseline characteristics, especially haemoglobin A1c (HbA1c), predict the likelihood of reaching HbA1c ≤ 7.0% or the risk of experiencing hypoglycaemia after the addition of insulin glargine to oral therapy in type 2 diabetes. METHODS Pooled patient-level data from 12 prospective, randomized, controlled studies that used insulin glargine in a treat-to-target titration regimen seeking fasting glucose levels ≤5.5 mmol/l (100 mg/dl) were analysed. Baseline characteristics were evaluated by logistic regression models as predictors of reaching a target HbA1c ≤ 7.0% or experiencing confirmed hypoglycaemia. The effect of prior glycaemic control was further explored by analysis of categorical ranges of baseline HbA1c. RESULTS Of 2312 participants, 95% completed 24 weeks of treatment. Lower HbA1c at baseline was independently associated with reaching HbA1c target [adjusted odds ratio (OR) for 1% difference: 0.538, p < 0.0001] and also with likelihood of experiencing confirmed hypoglycaemic events (adjusted OR: 0.835, p < 0.0001) at week 24. In an unadjusted analysis by baseline HbA1c range, the strong association between baseline control and attaining target HbA1c was confirmed (75% with baseline HbA1c < 8.0%, 60% with baseline HbA1c ≥ 8.0 and <9.0% and 38% with baseline HbA1c ≥ 9.0% attained HbA1c ≤ 7.0%). The incidence of hypoglycaemia confirmed <3.9 mmol/l (70 mg/dl) was higher in the lower baseline HbA1c ranges but severe hypoglycaemia was infrequent at all baseline HbA1c levels. CONCLUSIONS Systematically titrated insulin glargine, added to oral agents, was effective over a wide range of baseline HbA1c. Lower baseline HbA1c was the best clinical predictor of achieving HbA1c ≤ 7.0% and also associated with higher risk of glucose-confirmed hypoglycaemia. Severe hypoglycaemia was infrequent using this treatment approach.

Abstract
BACKGROUND Sexually transmitted infection with the human papillomavirus (hpv) is responsible for a significant burden of human cancers involving the cervix, anogenital tract, and oropharynx. Studies in the United States and Europe have demonstrated an alarming increase in the frequency of hpv-positive oropharyngeal cancer, but the same direct evidence does not exist in Canada. METHODS Using the London Health Sciences Centre pathology database, we identified tonsillar cancers diagnosed between 1993 and 2011. Real-time polymerase chain reaction was then used on pre-treatment primary-site biopsy samples to test for dna from the high-risk hpv types 16 and 18. The study cohort was divided into three time periods: 1993-1999, 2000-2005, and 2006-2011. RESULTS Of 160 tumour samples identified, 91 (57%) were positive for hpv 16. The total number of tonsillar cancers significantly increased from 1993-1999 to 2006-2011 (32 vs. 68), and the proportion of cases that were hpv-positive substantially increased (25% vs. 62%, p < 0.002). Those changes were associated with a marked improvement in 5-year overall survival (39% in 1993-1999 vs. 84% in 2006-2011, p < 0.001). When all factors were included in a multivariable model, only hpv status predicted treatment outcome. INTERPRETATION The present study is the first to provide direct evidence that hpv-related oropharyngeal cancer is increasing in incidence in a Canadian population. Given the long lag time between hpv infection and clinically apparent malignancy, oropharyngeal cancer will be a significant clinical problem for the foreseeable future despite vaccination efforts.

Abstract
AIM Addition and titration of basal insulin is usually effective in improving glycaemic control in type 2 diabetes, but fear of hypoglycaemia remains a barrier. Ability to predict which patients might be at greatest risk of hypoglycaemia might facilitate individualization of treatment and improve safety. The aim of this study was to obtain information about clinical characteristics which might predict risk of hypoglycaemia during initiation of basal insulin. METHODS Patient-level data from 2251 participants in 11 studies in which insulin glargine was started and titrated using similar treat-to-target methods was pooled and analysed with logistic regression models. RESULTS Participants had mean age 58 years, diabetes duration 8.9 years, body mass index 31.0 and baseline A1c 8.8%. They attained mean A1c 7.1% during 6 months of treatment with final mean glargine dosage 0.44 units/kg. Symptomatic hypoglycaemia occurred in 52%, glucose-confirmed hypoglycaemia (blood glucose <50 mg/dl) in 17%, repeated glucose-confirmed events in 7% and severe hypoglycaemia in 1.5%. Independent predictors of glucose-confirmed hypoglycaemia were younger age, lower body mass index, use of a sulphonylurea in addition to metformin, lower attained A1c and lower dosage of glargine. CONCLUSIONS These findings confirm low rates of clinically important hypoglycaemia using this method, and suggest that higher risk of hypoglycaemia may be suspected when patients needing insulin are younger, less obese and taking metformin and a sulphonylurea, and especially when A1c levels ≤7.0% are attained with glargine dosage ≤0.4 units/kg.

Abstract
BACKGROUND TRPS-1 is a new GATA transcription factor that is differentially expressed in breast cancer (BC) where it been found recently to regulate epithelial-to-mesenchymal transition (EMT). PATIENTS AND METHODS We carried out a quantitative immunohistochemistry (qIHC) analysis of TRPS-1 expression in 341 primary-stage I-III BC samples in relation to patient clinical characteristics as well as its prognostic value, especially in an estrogen receptor-positive (ER+) subgroup. RESULTS Higher TRPS-1 expression was significantly associated with a number of clinical and pathological characteristics as well as with improved overall survival (OS) and disease-free survival (DFS). Among stage I/II ER+ BC patients who received endocrine therapy alone, those with high TRPS-1 expression had significantly longer OS and DFS. There was also a strong association between TRPS-1 levels and the EMT marker E-cadherin in the ER+ invasive ductal carcinoma cases. Analysis of gene expression data on a panel of BC lines found that TRPS-1 expression was low or absent in BC lines having enriched mesenchymal features. CONCLUSIONS Our data indicated that TRPS-1 is an independent prognostic marker in early-stage BC and a new EMT marker that can distinguish patients with ER+ BC who will respond longer to adjuvant endocrine therapy.

Abstract
A calculation of the ratio of leptonic decay constants f(K+)/f(π+) makes possible a precise determination of the ratio of Cabibbo-Kobayashi-Maskawa (CKM) matrix elements |V(us)|/|V(ud)| in the standard model, and places a stringent constraint on the scale of new physics that would lead to deviations from unitarity in the first row of the CKM matrix. We compute f(K+)/f(π+) numerically in unquenched lattice QCD using gauge-field ensembles recently generated that include four flavors of dynamical quarks: up, down, strange, and charm. We analyze data at four lattice spacings a ≈ 0.06, 0.09, 0.12, and 0.15 fm with simulated pion masses down to the physical value 135 MeV. We obtain f(K+)/f(π+) = 1.1947(26)(37), where the errors are statistical and total systematic, respectively. This is our first physics result from our N(f) = 2+1+1 ensembles, and the first calculation of f(K+)/f(π+) from lattice-QCD simulations at the physical point. Our result is the most precise lattice-QCD determination of f(K+)/f(π+), with an error comparable to the current world average. When combined with experimental measurements of the leptonic branching fractions, it leads to a precise determination of |V(us)|/|V(ud)| = 0.2309(9)(4) where the errors are theoretical and experimental, respectively.
