Abstract
The full-length complementary (c)DNA of vacuolar-type-H(+) -ATPase B1 gene (vhab1) in marbled eel Anguilla marmorata with 1741 base pairs (bp) was identified. It contained a 1512 bp open reading frame encoding a polypeptide with 503 amino acids (55·9 kDa), an 83 bp 5'-untranslated region (UTR) and a 146 bp 3'-UTR. The expression levels of A. marmorata vhab1 in gill and kidney of A. marmorata were evaluated at different intervals during the exposure to various salinities (0, 10 and 25). The results indicated that the expression levels of A. marmorata vhab1 messenger (m)RNA in gill and kidney had a significant increase and reached the highest level at 1 h in brackish water (BW, salinity 10) group and 6 h in seawater (SW, salinity 25) group. Therefore, salinity did affect the relative expression level of A. marmorata vhab1 mRNA in gills, which exhibited the enhancement by c. 44 times in SW group when compared with that in fresh water. No remarkable difference in the expression of A. marmorata vhab1 mRNA was observed after 15 days of SW exposure (P > 0·05). V-H(+) -ATPase activity exhibited an increase by two- to three-fold when compared with that in gill and kidney from the control group. The consequence primarily suggested that A. marmorata vhab1 gene product in elvers from A. marmorata plays an important role in adaptation response to SW.

Abstract
The familial acute myeloid leukemia related factor gene (FAMLF) was previously identified from a familial AML subtractive cDNA library and shown to undergo alternative splicing. This study used real-time quantitative PCR to investigate the expression of the FAMLF alternative-splicing transcript consensus sequence (FAMLF-CS) in peripheral blood mononuclear cells (PBMCs) from 119 patients with de novo acute leukemia (AL) and 104 healthy controls, as well as in CD34+ cells from 12 AL patients and 10 healthy donors. A 429-bp fragment from a novel splicing variant of FAMLF was obtained, and a 363-bp consensus sequence was targeted to quantify total FAMLF expression. Kruskal-Wallis, Nemenyi, Spearman's correlation, and Mann-Whitney U-tests were used to analyze the data. FAMLF-CS expression in PBMCs from AL patients and CD34+ cells from AL patients and controls was significantly higher than in control PBMCs (P < 0.0001). Moreover, FAMLF-CS expression in PBMCs from the AML group was positively correlated with red blood cell count (rs =0.317, P=0.006), hemoglobin levels (rs = 0.210, P = 0.049), and percentage of peripheral blood blasts (rs = 0.256, P = 0.027), but inversely correlated with hemoglobin levels in the control group (rs = -0.391, P < 0.0001). AML patients with high CD34+ expression showed significantly higher FAMLF-CS expression than those with low CD34+ expression (P = 0.041). Our results showed that FAMLF is highly expressed in both normal and malignant immature hematopoietic cells, but that expression is lower in normal mature PBMCs.

Abstract
OBJECTIVE Lung cancer is the leading cause of cancer-related death in the world, particularly in major cities in China. We aimed to determine the benefit of survival and toxicity of Conformal Radiotherapy (CRT) combined with erlotinib-based multimodality therapy in newly diagnosed metastatic non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Newly diagnosed metastatic NSCLC patients were treated with CRT and erlotinib, with or without chemotherapy matched protocol. The patients received CRT with a dose of 30-66 Gy. Erlotinib was used at least one 28-day cycle. The primary end point was overall survival (OS). RESULTS Thirty-two patients were analyzed. The median OS was 517 days. Patients with only one metastasis showed longer survival than patients with multi-metastases (986 vs. 380 days, n = 8 vs. 24, p = .009). Patients with multiple metastases in brain conferred worse survival for patients without and with sole brain metastasis (321 vs. 700 days, n=11 vs 21, p = .006). There was no significant difference in median survival whether erlotinib was used as a first-, second- or third-line therapy (380 vs. 700 vs. 310 days, n = 10 vs. 15 vs 7, respectively. p = .179). Patients with TTCRT > 90 days had longer OS than patients with TTCRT ≤ 90 days (749 vs. 322 days, n = 11 vs. 21, p = .012). Patients tolerated treatment with limited Grade 1/2 toxicity. CONCLUSIONS In this study, patients with newly diagnosed metastatic NSCLC had survival benefits when erlotinib was used combined with CRT. Further prospective trials are needed to derive maximal benefit from the drug treatment.

Abstract
Wnts are considered as important factors in uterus developmental process and embryo implantation. Baicalin has been demonstrated to possess tocolytic properties. In order to investigate the effect of baicalin on the Wnt signaling pathway during the peri-implantation, pregnant Kuming mice were randomly divided into four groups: control group, baicalin group administered with 40mg/kg BW of baicalin through an intragastric gavage on day 2 to 7 of the pregnancy (Pd2-Pd7), mifepristone group treated with 4mg/kg BW of mifepristone, an abortifacient agent, via subcutaneous administration on Pd4, and baicalin+mifepristone group treated with their combination. The concentrations of the implantation-related steroid hormones (progesterone and estradiol) in the blood serum were measured with RIA. The gene and protein expression levels of the important molecules of the Wnt pathway (Wnt4, LRP6, Dkk1 and β-catenin) in the endometrium were detected with RT-PCR and western blot, respectively. The results showed that baicalin decreased (P<0.05) the estradiol levels on Pd4-Pd8 and increased (P<0.05) the progesterone levels on Pd3-Pd8. Mifepristone increased (P<0.05) the estradiol levels on Pd5-Pd8 and decreased (P<0.05) the progesterone levels on Pd6-Pd8. Compared with the control group, baicalin increased the gene and protein expression levels of Wnt4, LRP6 and β-catenin (P<0.05) and decreased the gene and protein expression levels of Dkk1 (P<0.05) during the middle-to-late stage of the experiment in mice uterine tissue. Baicalin alleviated the mifepristone-induced increase or decrease in the serum levels of progesterone and estradiol, and the gene or protein expression levels of Wnt4, LRP6 and β-catenin. The tocolytic properties tocolysis of baicalin may be realized through regulating the levels of estrogen/progesterone and the important components of canonical Wnt signaling pathway during the embryo implantation process intervened with the subcutaneous administration of mifepristone in the mice.

Abstract
In biomedical imaging, edge sharpness is an important yet often overlooked image quality metric. In this work, a semi-automatic method to quantify edge sharpness in the presence of significant noise is presented with application to magnetic resonance imaging (MRI). The method is based on parametric modeling of image edges. First, an edge map is automatically generated and one or more edges-of-interest (EOI) are manually selected using graphical user interface. Multiple exclusion criteria are then enforced to eliminate edge pixels that are potentially not suitable for sharpness assessment. Second, at each pixel of the EOI, an image intensity profile is read along a small line segment that runs locally normal to the EOI. Third, the profiles corresponding to all EOI pixels are individually fitted with a sigmoid function characterized by four parameters, including one that represents edge sharpness. Last, the distribution of the sharpness parameter is used to quantify edge sharpness. For validation, the method is applied to simulated data as well as MRI data from both phantom imaging and cine imaging experiments. This method allows for fast, quantitative evaluation of edge sharpness even in images with poor signal-to-noise ratio. Although the utility of this method is demonstrated for MRI, it can be adapted for other medical imaging applications.

Abstract
L-arginine (Arg) is an indispensable amino acid in avians and is required for growth. The aim of this study was to investigate the effects of L-Arg on protein synthesis and genes expression involved in target of rapamycin (TOR) signaling pathway in chicken enterocytes. Cells were cultured for 4 days in L-Arg-free Dulbecco's modified Eagle's medium containing 10, 100, 200, 400, or 600 μM L-Arg. Cell growth, cell cycle, protein synthesis, and protein degradation as well as mRNA expression levels of TOR, ribosomal protein S6 kinase 1 (S6K1), and eukaryotic initiation factor 4E-binding protein 1 (4E-BP1) were determined. The results showed that cell viability was enhanced by L-Arg with a maximal response at 10 to 400 μM. Increasing extracellular concentrations of L-Arg from 10 to 400 μM increased the cells in S and G2/M phase to a significant extent and decreased cell numbers in G0/G1 phase. Further more, addition of 100, 200, or 400 μM L-Arg to culture medium increased protein synthesis and reduced protein degradation in chicken intestinal epithelial cells. Consistent with the data on cell growth and protein turnover, supplementation of 100, 200, or 400 μM L-Arg increased the mRNA abundances of TOR, 4E-BP1, and S6K1. It was concluded the action of L-Arg involves in upregulating the genes expression of TOR cell signaling pathway which increases protein synthesis and reduces protein degradation.

Abstract
Interleukin (IL)-1β is now emerging as a critical cytokine in the pathogenesis of T helper type 17 (Th17)-mediated skin diseases, including psoriasis. Psoriatic keratinocytes are a major source of IL-1β; however, the mechanisms triggering IL-1β processing remain unknown. Recently, an acute-phase protein serum amyloid A (SAA) has been identified as a danger signal that triggers inflammasome activation and IL-1β secretion. In this study, we detected increased SAA mRNA and protein expression in psoriatic epidermis. In cultured keratinocytes, SAA up-regulated the expression of pro-IL-1β and secretion of mature IL-1β. On the transcriptional level, blocking Toll-like receptor-2 (TLR-2), TLR-4 or nuclear factor kappa B (NF-κB) attenuated SAA-induced expression of IL-1β mRNA. SAA up-regulated caspase-1 and NACHT, LRR and PYD domains-containing protein 3 (NLRP3) expression in keratinocytes. Inhibiting caspase-1 activity and silencing NLRP3 decreased IL-1β secretion, confirming NLRP3 as the SAA-responsive inflammasome on the post-transcriptional level. The mechanism of SAA-triggered NLRP3 activation and subsequent IL-1β secretion was found to involve the generation of reactive oxygen species. Finally, the expression of SAA by keratinocytes was up-regulated by IL-17A. Taken together, our results indicate that keratinocyte-derived SAA triggers a key inflammatory mediator, IL-1β, via NLRP3 inflammasome activation, providing new potential targets for the treatment of this chronic skin disease.

Abstract
Based on data samples collected with the BESIII detector at the BEPCII collider at nine center of mass energies from 4.21 to 4.42 GeV, we search for the production of e^{+}e^{-}→ωχ_{cJ} (J=0, 1, 2). The process e^{+}e^{-}→ωχ_{c0} is observed for the first time, and the Born cross sections at sqrt[s]=4.23 and 4.26 GeV are measured to be (55.4±6.0±5.9) and (23.7±5.3±3.5) pb, respectively, where the first uncertainties are statistical and the second are systematic. The ωχ_{c0} signals at the other seven energies and the e^{+}e^{-}→ωχ_{c1} and ωχ_{c2} signals are not significant, and the upper limits on the cross sections are determined. By examining the ωχ_{c0} cross section as a function of center of mass energy, we find that it is inconsistent with the line shape of the Y(4260) observed in e^{+}e^{-}→π^{+}π^{-}J/ψ. Assuming the ωχ_{c0} signals come from a single resonance, we extract the mass and width of the resonance to be (4230±8±6) MeV/c^{2} and (38±12±2) MeV, respectively, and the statistical significance is more than 9σ.

ACTA ACUST UNITED AC 2015; 48:440-6.

Abstract
The present study investigated the effect of silibinin, the principal potential
anti-inflammatory flavonoid contained in silymarin, a mixture of flavonolignans
extracted from Silybum marianum seeds, on palmitate-induced insulin
resistance in C2C12 myotubes and its potential molecular mechanisms. Silibinin
prevented the decrease of insulin-stimulated 2-NBDG
(2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino]-2-deoxy-D-glucose) uptake and the
downregulation of glutamate transporter type 4 (GLUT4) translocation in C2C12
myotubes induced by palmitate. Meanwhile, silibinin suppressed the palmitate-induced
decrease of insulin-stimulated Akt Ser473 phosphorylation, which was reversed by
wortmannin, a specific inhibitor of phosphatidylinositol-3-kinase (PI3K). We also
found that palmitate downregulated insulin-stimulated Tyr632 phosphorylation of
insulin receptor substrate 1 (IRS-1) and up-regulated IRS-1 Ser307 phosphorylation.
These effects were rebalanced by silibinin. Considering several serine/threonine
kinases reported to phosphorylate IRS-1 at Ser307, treatment with silibinin
downregulated the phosphorylation of both c-Jun N-terminal kinase (JNK) and nuclear
factor-κB kinase β (IKKβ), which was increased by palmitate in C2C12 myotubes
mediating inflammatory status, whereas the phosphorylation of PKC-θ was not
significantly modulated by silibinin. Collectively, the results indicated that
silibinin prevented inhibition of the IRS-1/PI3K/Akt pathway, thus ameliorating
palmitate-induced insulin resistance in C2C12 myotubes.

Abstract
The X-ray free-electron laser has opened a new era for photon science, improving the X-ray brightness by ten orders of magnitude over previously available sources. Similar to an optical laser, the spectral and temporal structure of the radiation pulses can be tailored to the specific needs of many experiments by accurately manipulating the lasing medium, that is, the electron beam. Here we report the generation of mJ-level two-colour hard X-ray pulses of few femtoseconds duration with an XFEL driven by twin electron bunches at the Linac Coherent Light Source. This performance represents an improvement of over an order of magnitude in peak power over state-of-the-art two-colour XFELs. The unprecedented intensity and temporal coherence of this new two-colour X-ray free-electron laser enable an entirely new set of scientific applications, ranging from X-ray pump/X-ray probe experiments to the imaging of complex biological samples with multiple wavelength anomalous dispersion. Two-colour X-ray pulses from free-electron lasers can be used to probe ultrafast dynamics, but the total power is a fraction of the saturation power. Here, Marinelli et al. use twin electron bunches to reach full saturation power and increase the two-colour intensity by an order of magnitude at hard-X-ray energies.

Abstract
INTRODUCTION The combination of reduced dose of local anesthetics (LA) and highly lipid-soluble synthetic opioids for patients undergoing transurethral surgery could reduce block duration and side-effects. However, it remains unclear what are the most appropriate levels of low dose and the extent to which the side-effects could be controlled. A meta-analysis was conducted to address this concern. MATERIALS AND METHODS Based on twelve randomized controlled trials, this meta-analysis pooled previous results to generate integrated evidence. RESULTS Combined low dose of LA and opioids had similar sensory block and significantly shorter motor block duration (weighted mean difference: -39.31 min, 95% confidence interval (CI): -50.58--28.05, P < 0.00001) compared with single use of LA. There was no evidence of higher risk of analgesic failure in the combination group. In addition, combined low dose LA and opioids was associated with significantly reduced rate of postoperative hypotension (risk ratios (RR): 0.60, 95% CI: 0.37-0.96, P = 0.03) and shivering (RR: 0.27, 95% CI: 0.11-0.64, P = 0.003), but with higher rate of sedation (RR: 3.14, 95% CI: 1.02-9.66, P = 0.05). CONCLUSION Combined low dose LA and opioids is a better choice for patients received transurethral surgery compared with single use of intrathecal LA.

Abstract
PTEN serves as an intrinsic brake on neurite outgrowth, but the regulatory mechanism that governs its action is not clear. In the present study, miR-29a was found to increase neurite outgrowth by decreasing PTEN expression. Results showed that miR-92a-1, miR-29a, miR-92b, and miR-29c expression levels increased during nerve growth factor (NGF)-induced differentiation of PC12 cells. Based on in silico analysis of possible miR-29a targets, PTEN mRNA may be a binding site for miR-29a. A protein expression assay and luciferase reporter assay showed that miR-29a could directly target the 3'-UTRs (untranslated regions) of PTEN mRNA and down-regulate the expression of PTEN. PC12 cells infected with lentiviral pLKO-miR-29a showed far higher levels of miR-29a and Akt phosphorylation level than those infected with control. This promoted neurite outgrowth of PC12 cells. Collectively, these results indicate that miR-29a is an important regulator of neurite outgrowth via targeting PTEN and that it may be a promising therapeutic target for neural disease.

Abstract
The Linac Coherent Light Source has added a self-seeding capability to the soft x-ray range using a grating monochromator system. We report the demonstration of soft x-ray self-seeding with a measured resolving power of 2000-5000, wavelength stability of 10(-4), and an increase in peak brightness by a factor of 2-5 across the photon energy range of 500-1000 eV. By avoiding the need for a monochromator at the experimental station, the self-seeded beam can deliver as much as 50-fold higher brightness to users.

Prefrontal cortex markers of suicidal vulnerability in mood disorders: a model-based structural neuroimaging study with a translational perspective. Transl Psychiatry 2015; 5:e516. [PMID: 25710122 PMCID: PMC4445751 DOI: 10.1038/tp.2015.1] [Citation(s) in RCA: 82] [Impact Index Per Article: 9.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2014] [Revised: 12/11/2014] [Accepted: 12/19/2014] [Indexed: 11/11/2022] Open
Abstract
The vulnerability to suicidal behavior has been modeled in deficits in both valuation and cognitive control processes, mediated by ventral and dorsal prefrontal cortices. To uncover potential markers of suicidality based on this model, we measured several brain morphometric parameters using 1.5T magnetic resonance imaging in a large sample and in a specifically designed study. We then tested their classificatory properties. Three groups were compared: euthymic suicide attempters with a past history of mood disorders and suicidal behavior (N=67); patient controls with a past history of mood disorders but not suicidal behavior (N=82); healthy controls without any history of mental disorder (N=82). A hypothesis-driven region-of-interest approach was applied targeting the orbitofrontal cortex (OFC), ventrolateral (VLPFC), dorsal (DPFC) and medial (including anterior cingulate cortex; MPFC) prefrontal cortices. Both voxel-based (SPM8) and surface-based morphometry (Freesurfer) analyses were used to comprehensively evaluate cortical gray matter measure, volume, surface area and thickness. Reduced left VLPFC volume in attempters vs both patient groups was found (P=0.001, surviving multiple comparison correction, Cohen's d=0.65 95% (0.33-0.99) between attempters and healthy controls). In addition, reduced measures in OFC and DPFC, but not MPFC, were found with moderate effect sizes in suicide attempters vs healthy controls (Cohen's d between 0.34 and 0.52). Several of these measures were correlated with suicidal variables. When added to mood disorder history, left VLPFC volume increased within-sample specificity in identifying attempters in a significant but limited way. Our study, therefore, confirms structural prefrontal alterations in individuals with histories of suicide attempts. A future clinical application of these markers will, however, necessitate further research.
