Abstract
Local parity-odd domains are theorized to form inside a quark-gluon plasma which has been produced in high-energy heavy-ion collisions. The local parity-odd domains manifest themselves as charge separation along the magnetic field axis via the chiral magnetic effect. The experimental observation of charge separation has previously been reported for heavy-ion collisions at the top RHIC energies. In this Letter, we present the results of the beam-energy dependence of the charge correlations in Au+Au collisions at midrapidity for center-of-mass energies of 7.7, 11.5, 19.6, 27, 39, and 62.4 GeV from the STAR experiment. After background subtraction, the signal gradually reduces with decreased beam energy and tends to vanish by 7.7 GeV. This implies the dominance of hadronic interactions over partonic ones at lower collision energies.

Abstract
We report the STAR measurements of dielectron (e(+)e(-)) production at midrapidity (|y(ee)|<1) in Au+Au collisions at √[s(NN)]=200 GeV. The measurements are evaluated in different invariant mass regions with a focus on 0.30-0.76 (ρ-like), 0.76-0.80 (ω-like), and 0.98-1.05 (ϕ-like) GeV/c(2). The spectrum in the ω-like and ϕ-like regions can be well described by the hadronic cocktail simulation. In the ρ-like region, however, the vacuum ρ spectral function cannot describe the shape of the dielectron excess. In this range, an enhancement of 1.77±0.11(stat)±0.24(syst)±0.33(cocktail) is determined with respect to the hadronic cocktail simulation that excludes the ρ meson. The excess yield in the ρ-like region increases with the number of collision participants faster than the ω and ϕ yields. Theoretical models with broadened ρ contributions through interactions with constituents in the hot QCD medium provide a consistent description of the dilepton mass spectra for the measurement presented here and the earlier data at the Super Proton Synchrotron energies.

Abstract
Rapidity-odd directed flow (v1) measurements for charged pions, protons, and antiprotons near midrapidity (y=0) are reported in sNN=7.7, 11.5, 19.6, 27, 39, 62.4, and 200 GeV Au+Au collisions as recorded by the STAR detector at the Relativistic Heavy Ion Collider. At intermediate impact parameters, the proton and net-proton slope parameter dv1/dy|y=0 shows a minimum between 11.5 and 19.6 GeV. In addition, the net-proton dv1/dy|y=0 changes sign twice between 7.7 and 39 GeV. The proton and net-proton results qualitatively resemble predictions of a hydrodynamic model with a first-order phase transition from hadronic matter to deconfined matter, and differ from hadronic transport calculations.

Abstract
Azimuthal angular correlations of charged hadrons with respect to the axis of a reconstructed (trigger) jet in Au+Au and p+p collisions at √[s(NN)]=200 GeV in STAR are presented. The trigger jet population in Au+Au collisions is biased toward jets that have not interacted with the medium, allowing easier matching of jet energies between Au+Au and p+p collisions while enhancing medium effects on the recoil jet. The associated hadron yield of the recoil jet is significantly suppressed at high transverse momentum (pTassoc) and enhanced at low pTassoc in 0%-20% central Au+Au collisions compared to p+p collisions, which is indicative of medium-induced parton energy loss in ultrarelativistic heavy-ion collisions.

Abstract
We report the beam energy (sqrt[sNN]=7.7-200 GeV) and collision centrality dependence of the mean (M), standard deviation (σ), skewness (S), and kurtosis (κ) of the net-proton multiplicity distributions in Au+Au collisions. The measurements are carried out by the STAR experiment at midrapidity (|y|<0.5) and within the transverse momentum range 0.4<pT<0.8 GeV/c in the first phase of the Beam Energy Scan program at the Relativistic Heavy Ion Collider. These measurements are important for understanding the quantum chromodynamic phase diagram. The products of the moments, Sσ and κσ2, are sensitive to the correlation length of the hot and dense medium created in the collisions and are related to the ratios of baryon number susceptibilities of corresponding orders. The products of moments are found to have values significantly below the Skellam expectation and close to expectations based on independent proton and antiproton production. The measurements are compared to a transport model calculation to understand the effect of acceptance and baryon number conservation and also to a hadron resonance gas model.

Abstract
BACKGROUND Collaterals to occluded infarct-related coronary arteries (IRA) have been observed after the onset of acute ST-elevation myocardial infarction (STEMI). We sought to investigate the impact of early coronary collateralization, as evidenced by angiography, on myocardial reperfusion and outcomes after primary percutaneous coronary intervention (PCI). METHODS Acute procedural results, ST-segment resolution (STR), enzymatic infarct size, echocardiographic left ventricular function, and major adverse cardiac events (MACE) at 6-month follow-up were assessed in 389 patients with STEMI undergoing primary PCI for occluded IRA (TIMI flow grade 0 or 1) within 12 hours of symptom-onset. Angiographic coronary collateralization to the occluded IRA at first contrast injection was graded according to the Rentrop scoring system. RESULTS Low (Rentrop score of 0 or 1) and high (Rentrop score of 2 or 3) coronary collateralization was detected in 329 and 60 patients, respectively. Patients with high collateralization more commonly had prior stable angina and right coronary artery occlusion, but less often had left anterior descending artery occlusion. At baseline, these patients presented with less extent of ST-segment elevation and lower serum levels of creatine kinase myocardial band (CK-MB) and cardiac troponin I (cTnI). Procedural success rate, STR, corrected TIMI flame count, and area under the curve of CK-MB and cTnI measurements after the procedure were similar between patients with high collateralization and those with low collateralization (for all comparisons P > 0.05). There were no differences in left ventricular ejection fraction and rates of MACE at 6 months according to baseline angiographic collaterals to occluded IRA. CONCLUSIONS In patients with acute STEMI undergoing primary PCI within 12 hours of symptom-onset, coronary collateralization to the occluded IRA was influenced by clinical and angiographic features. Early recruitment of collaterals limits infarct size at baseline, but has no significant impact on myocardial reperfusion after the procedure and subsequent left ventricular function and clinical outcomes.

Abstract
The measurement of J/ψ azimuthal anisotropy is presented as a function of transverse momentum for different centralities in Au+Au collisions at sqrt[s(NN)]=200 GeV. The measured J/ψ elliptic flow is consistent with zero within errors for transverse momentum between 2 and 10 GeV/c. Our measurement suggests that J/ψ particles with relatively large transverse momenta are not dominantly produced by coalescence from thermalized charm quarks, when comparing to model calculations.

Abstract
An analytical solution is presented for wire coating by drawdown of an extruded annular melt. The solution is developed with the assumption that the pressures inside and outside the film are equal; a process in which these pressures differ, such as a vacuum inside the film, is treated as a limiting case.

Abstract
Elliptic flow (v(2)) values for identified particles at midrapidity in Au + Au collisions, measured by the STAR experiment in the beam energy scan at RHIC at sqrt[s(NN)] = 7.7-62.4 GeV, are presented. A beam-energy-dependent difference of the values of v(2) between particles and corresponding antiparticles was observed. The difference increases with decreasing beam energy and is larger for baryons compared to mesons. This implies that, at lower energies, particles and antiparticles are not consistent with the universal number-of-constituent-quark scaling of v(2) that was observed at sqrt[s(NN)] = 200 GeV.

Abstract
MicroRNAs have key roles in tumor metastasis. Here, we describe the regulation and function of miR-34a and miR-34c (miR-34a/c) in breast cancer metastasis. Expression analysis verified that miR-34a/c expression is significantly decreased in metastatic breast cancer cells and human primary breast tumors with lymph node metastases. Overexpression of miR-34a/c could inhibit breast cancer cell migration and invasion in vitro and distal pulmonary metastasis in vivo. Further studies revealed that Fos-related antigen 1 (Fra-1 or Fosl1) is a downstream target of miR-34a/c as miR-34a/c bound directly to the 3'untranslated region of Fra-1, subsequently reducing both the mRNA and protein levels of Fra-1. Silencing of Fra-1 recapitulated the effects of miR-34a/c overexpression, whereas enforced expression of Fra-1 reverses the suppressive effects of miR-34a/c. Moreover, significant downregulation of miR-34a in metastatic breast cancer tissues was found to be inversely correlated with Fra-1 expression. Our results demonstrate that miR-34a/c functions as a metastasis suppressor to regulate breast cancer migration and invasion through targeting Fra-1 oncogene and suggest a therapeutic application of miR-34 in breast cancer.

Abstract
The purpose of this study was to investigate the clinical and laboratorial characteristics of patients with systemic lupus erythematosus (SLE) manifesting with negative immunofluorescence anti-nuclear antibodies (IFANA) after treatment for the better understanding of negative conversion of IFANA. Demographic characteristics, clinical and laboratory data of hospitalized SLE patients between March 2006 and May 2011 were retrospectively reviewed. Fifteen cases with negative IFANA were identified in 960 patients. All of the 15 patients were severe, 11 patients manifested with nephritic range proteinuria and hypoalbuminemia, 8 patients were complicated with severe infection and all of the patients had been treated with glucocorticoid and immunosuppressant. Anti-ENA antibodies were positive in 4 of 15 patients. Eight patients died after average 1-year follow-up. Collectively, negative IFANA is mainly attributed to nephritic-range proteinuria; and large-dose glucocorticoid, immunosuppressant and severe infection are also important factors for negative IFANA. Antinuclear antibody can be detected in some SLE patients with negative IFANA by changing the detection method and titer. Negative conversion of IFANA often indicates unfavorable prognosis for severe patients.

Abstract
STAR's measurements of directed flow (v1) around midrapidity for π±, K±, KS0, p, and p[over ¯] in Au+Au collisions at √[sNN]=200 GeV are presented. A negative v1(y) slope is observed for most of produced particles (π±, K±, KS0, and p[over ¯]). In 5%-30% central collisions, a sizable difference is present between the v1(y) slope of protons and antiprotons, with the former being consistent with zero within errors. The v1 excitation function is presented. Comparisons to model calculations (RQMD, UrQMD, AMPT, QGSM with parton recombination, and a hydrodynamics model with a tilted source) are made. For those models which have calculations of v1 for both pions and protons, none of them can describe v1(y) for pions and protons simultaneously. The hydrodynamics model with a tilted source as currently implemented cannot explain the centrality dependence of the difference between the v1(y) slopes of protons and antiprotons.

Abstract
BACKGROUND Systemic inflammatory response syndrome (SIRS) can occur in association with cardiopulmonary bypass (CPB) surgery, resulting in multiple organ dysfunction (MOD). Activated neutrophils have been implicated as major inciting factors in this process. Neutrophil-depleting filters incorporated within the extracorporeal blood circuit during CPB have been developed and evaluated, with inconsistent clinical results. METHODS A novel, biomimetic, selective cytopheretic device (SCD) was tested in vitro within a blood circuit to assess safety and interactions with blood components and further evaluated ex vivo in a bovine model of CPB surgery during ventricular assist device implantation. RESULTS In vitro blood circuit studies demonstrated that the SCD reduces circulating neutrophils while maintaining low rates of hemolysis compared to current leukocyte-reduction filters. In the bovine CPB model, animals without SCD treatment (No SCD) demonstrated an increase in circulating white blood cell (WBC) and neutrophil counts, steadily increasing throughout CPB. SCD with only systemic heparin anticoagulation (SCD-H) acutely reduced neutrophils for the first 2 hrs of CPB, but followed with a greater than 6-fold increase in neutrophil counts. SCD treatment with regional citrate anticoagulation along the SCD circuit (SCD-C) reduced systemic neutrophil counts throughout 4 hrs of CPB despite lower amounts of eluted cells from the SCD. When analyzed for immature neutrophils, the control and SCD-H showed increasing counts at later time-points, not seen in the SCD-C group, suggesting a more complex mechanism of action than simple leukoreduction. CONCLUSIONS These results suggest that SCD-C therapy may disrupt the systemic leukocyte response during CPB, leading to improved outcomes for CPB-mediated MOD.

Abstract
We apply external uniaxial stress to tailor the optical properties of In(x)Ga(1-x)As/GaAs quantum dots. Unexpectedly, the emission energy of single quantum dots controllably shifts to both higher and lower energies under tensile strain. Theoretical calculations using a million atom empirical pseudopotential many-body method indicate that the shifting direction and magnitude depend on the lateral extension and more interestingly on the gallium content of the quantum dots. Our experimental results are in good agreement with the underlying theory.

Abstract
The cDNA encoding noggin2 protein was obtained from the brain and spinal cord cDNA library of Gekko japonicus. The size of the noggin2 transcript and its expression in different tissues were analyzed by Northern blot analysis. In situ hybridization revealed positive hybridization signals in both gray and white matter of the spinal cord. Changes in noggin2 expression in the spinal cord after tail amputation were examined by real-time PCR. The noggin2 was expressed in the normal spinal cord and down-regulated three days after tail amputation, reaching the lowest level at two weeks, during the time course when we followed the expression levels. We concluded that the expression of noggin2 is affected by the process of spinal cord injury and regeneration.
