摘要： Hyperlipidemia has been demonstrated to evoke Alzheimer disease (AD) pathologies such as Amyloid-beta (A beta) deposition and synaptogenesis dysfunction in the hippocampus. Curcumin gives protection against anti-amyloid properties and synaptogenesis dysfunction. Curcumin-Nicotinate (CurTn), a new type of curcumin derivative, ameliorates cognitive impairment by rescuing autophagic flux in the CA1 hippocampus of diabetic rats. However, whether Curtn possesses an antagonistic effect on AD-related pathologies in the hippocampus induced by hyperlipidemia remains ill-defined. The present study aims to investigate whether CurTn alleviates synaptogenesis dysfunction by promoting the activation of brain-derived neurotrophic factor (BDNF)/tyrosine kinase receptor B (TrkB)/cAMP-response element binding protein (CREB) signaling and whether the underlying fundamental mechanism involves the elimination of A beta deposition due to Idol/low-density lipoprotein receptor (LDLR) signaling in the hippocampus of high-fat diet (HFD)-induced hyperlipidemia rats. The results demonstrated that CurTn not only improved synaptogenesis dysfunction in the hippocampus of HFD rats, as evidenced by the increases in the expressions of synapse-related proteins postsynaptic density protein 95 (PSD-95), synapsin-1, and Glutamate receptor 1 (GluR1), but also activated BDNF/TrkB/CREB signaling, as evidenced by the elevation of the expressions of BDNF, pTrkB, and CREB. Moreover, CurTn modulated the Idol/LDLR pathway in the hippocampus of HFD rats, as evidenced by the decreased expression of Idol and the increased expression of LDLR. Furthermore, CurTn eliminated the deposition of A beta, as evidenced by the reduction in the content of A beta 40 and A beta 42. These results reveal that CurTn may attenuate synaptogenesis dysfunction by activating BDNF/TrkB/CREB signaling, as the possible result of the modulation of Idol/LDLR signaling to eliminate A beta deposition in the hippocampus of HFD rats.

摘要： Using a data sample of psi(3770) events collected with the BESIII detector at BEPCII corresponding to an integrated luminosity of 2.9 fb-1, we report a measurement of A spin polarization in e+ e- -> Lambda(Lambda) over bar at = root s = 3.773 GeV. The significance of polarization is found to be 2 sigma including the systematic uncertainty, which implies a zero phase between the transition amplitudes of the Lambda(Lambda) over bar helicity states. This phase can be interpreted in terms of psionic form factors, and is determined to be Delta Phi(Psi) = Phi(Psi)(E) - Phi(Psi)(M) = (71(-46)(+66) +/- 5)degrees. Similarly, the ratio between the form factors is found to be R-psi = vertical bar G(E)(Psi)/G(M)(Psi)vertical bar = 0.48(-0.35)(+0.21) +/- 0.03. The first uncertainties are statistical and the second systematic.

摘要： We study the direct production of the JPC=1++ charmonium state χc1(1P) in electron-positron annihilation by carrying out an energy scan around the mass of the χc1(1P). The data were collected with the BESIII detector at the BEPCII collider. An interference pattern between the signal process e+e-→χc1(1P)→γJ/ψ→γμ+μ- and the background processes e+e-→γISRJ/ψ→γISRμ+μ- and e+e-→γISRμ+μ- is observed by combining all the data samples. The χc1(1P) signal is observed with a significance of 5.1σ. This is the first observation of a C-even state directly produced in e+e- annihilation. The electronic width of the χc1(1P) resonance is determined to be Γee=(0.12-0.08+0.13) eV, which is of the same order of magnitude as theoretical calculations. © 2022 authors.

摘要： Using a data sample of (448.1 +/- 2.9) x 10(6) psi(3686) decays collected at an e(+)e(& minus;) center-of-mass energy of 3.686 GeV by the BESIII detector at Beijing Electron Positron Collider II, we report an observation of the hindered electromagnetic Dalitz decay psi(3686) -> e(+)e(& minus;)eta(c) with a significance of 7.9 sigma. The branching fraction is determined to be B(psi(3686) -> e(+)e(& minus;)eta(c)) = (3.77 +/- 0.40(stat) +/- 0.18(syst)) x 10(& minus;5), agreeing well with the prediction of the vector meson dominance model. This is the first measurement of the electromagnetic Dalitz transition between the psi(3686) and the eta(c), which provides new insight into the electromagnetic properties of this decay, and offers new opportunities to measure the absolute branching fractions of eta(c) decays.

摘要： Utilizing the data set corresponding to an integrated luminosity of 3.19 fb(-1) collected by the BESIII detector at a center-of-mass energy of 4.178 GeV, we perform an amplitude analysis of the D-s(+) -> pi(+) pi(-) pi(+) decay. The sample contains 13,797 candidates with a signal purity of similar to 80%. The amplitude and phase of the contributing pi pi S wave are measured based on a quasi-model-independent approach, along with the amplitudes and phases of the P and D waves parametrized by Breit-Wigner models. The fit fractions of different intermediate decay channels are also reported.

摘要： We study the processes e(+)e(-) -> (KSDs+D)-D-0*(-) and e(+)e(-) -> (KSDs)-D-0*D-+(-) as well as their charge conjugated processes, at five center-of-mass energies between 4.628 and 4.699 GeV, using data samples corresponding to an integrated luminosity of 3.8 fb(-1) collected by the BESIII detector at the BEPCII storage ring. Based on a partial reconstruction technique, we find evidence of a structure near the thresholds for Ds+D*- and D-s*(+) D- production in the K-S(0) recoil-mass spectrum, which we refer to as the Z(cs) (3985)(0). Fitting with a Breit-Wigner line shape, we find the mass of the structure to be (3992.2 +/- 1.7 +/- 1.6) MeV/c(2) and the width to be (7.7(-3.8)(+4.1) +/- 4.3) MeV, where the first uncertainties are statistical and the second are systematic. The significance of the Z(cs)(3985)(0) signal is found to be 4.6s including both the statistical and systematic uncertainty. We report the Born cross section multiplied by the branching fraction at different energy points. The mass of the Z(cs) (3985)(0) is close to that of the Z(cs)(3985)(+). Assuming SU(3) symmetry, the cross section of the neutral channel is consistent with that of the charged one. Hence, we conclude that the Z(cs) (3985)(0) is the isospin partner of the Z(cs)(3985)(+).

摘要： A search for invisible decays of the Lambda baryon is carried out in the process J/psi -> Lambda(Lambda) over bar based on (1.0087 +/- 0.0044) x 10(10) J/psi events collected with the BESIII detector located at the BEPCII storage ring. No signals are found for the invisible decays of. baryon, and the upper limit of the branching fraction is determined to be 7.4 x 10(-5) at the 90% confidence level. This is the first search for invisible decays of baryons; such searches will play an important role in constraining dark sector models related to the baryon asymmetry.

摘要： BACKGROUND: Circular RNAs (circRNAs) are one type of RNAs with many different functions. circRNAs are very crucial in human malignancy progression. However, few studies have investigated the function and exact mechanism of circRNAs in neuroblastoma. In the current study, we investigated the biological function of circ0125803 in the proliferation and metastasis of neuroblastoma. METHODS: A high-throughput circRNA microarray sequencing was conducted to screen differentially expressed circRNAs and in neuroblastoma. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression level of circRNA and miRNA. RNA immunoprecipitation and dual luciferase reporter experiments were both conducted to investigate the molecular interaction mechanism of circ0125803 in neuroblastoma. RESULTS: We identified hsa_circ_0125803 (circ0125803) as an extremely upregulated circRNA in neuroblastoma samples. Knockdown of circ0125803 significantly decreased the growth rate and invasion rate in neuroblastoma. Our data demonstrated upregulation of circ0125803 promotes the neuroblastoma progression by blocking miR-197-5p and upregulating E2F1 expression. CONCLUSION: This study uncovered the biological function of the circ0125803-miR-197-5p-E2F1 axis in neuroblastoma metastasis and growth.

摘要： The decay $$D \rightarrow K^-\pi ^+$$ is studied in a sample of quantum-correlated $$D{\bar{D}}$$ pairs, based on a data set corresponding to an integrated luminosity of 2.93fb $$^{-1}$$ collected at the $$\psi (3770)$$ resonance by the BESIII experiment. The asymmetry between $$C\!P$$ -odd and $$C\!P$$ -even eigenstate decays into $$K^-\pi ^+$$ is determined to be $${{\mathcal {A}}}_{K\pi } = 0.132 \pm 0.011 \pm 0.007$$ , where the first uncertainty is statistical and the second is systematic. This measurement is an update of an earlier study exploiting additional tagging modes, including several decay modes involving a $$K^0_L$$ meson. The branching fractions of the $$K^0_L$$ modes are determined as input to the analysis in a manner that is independent of any strong phase uncertainty. Using the predominantly $$C\!P$$ -even tag $$D\rightarrow \pi ^+\pi ^-\pi ^0$$ and the ensemble of $$C\!P$$ -odd eigenstate tags, the observable $${{\mathcal {A}}}_{K\pi }^{\pi \pi \pi ^0}$$ is measured to be $$0.130 \pm 0.012 \pm 0.008$$ . The two asymmetries are sensitive to $$r_D^{K\pi }\cos \delta _D^{K\pi }$$ , where $$r_D^{K\pi }$$ and $$\delta _D^{K\pi }$$ are the ratio of amplitudes and phase difference, respectively, between the doubly Cabibbo-suppressed and Cabibbo-favoured decays. In addition, events containing $$D \rightarrow K^-\pi ^+$$ tagged by $$D \rightarrow K^0_{S,L} \pi ^+\pi ^-$$ are studied in bins of phase space of the three-body decays. This analysis has sensitivity to both $$r_D^{K\pi }\cos \delta _D^{K\pi }$$ and $$r_D^{K\pi }\sin \delta _D^{K\pi }$$ . A fit to $${{\mathcal {A}}}_{K\pi }$$ , $${{\mathcal {A}}}_{K\pi }^{\pi \pi \pi ^0}$$ and the phase-space distribution of the $$D \rightarrow K^0_{S,L} \pi ^+\pi ^-$$ tags yields $$\delta _D^{K\pi }= \left( 187.6 {^{+8.9}_{-9.7}}{^{+5.4}_{-6.4}} \right) ^{\circ }$$ , where external constraints are applied for $$r_D^{K\pi }$$ and other relevant parameters. This is the most precise measurement of $$\delta _D^{K\pi }$$ in quantum-correlated $$D{\bar{D}}$$ decays.

摘要： We measure the inclusive semielectronic decay branching fraction of the D-s(+) meson. A double-tag technique is applied to e(+)e(-) annihilation data collected by the BESIII experiment at the BEPCII collider, operating in the center-of-mass energy range 4.178-4.230 GeV. We select positrons from D (+)(s) -> Xe+nu(e) with momenta greater than 200 MeV/c and determine the laboratory momentum spectrum, accounting for the effects of detector efficiency and resolution. The total positron yield and semielectronic branching fraction are determined by extrapolating this spectrum below the momentum cutoff. We measure the D-s(+) semielectronic branching fraction to be (6.30 +/- 0.13(stat.) +/- 0.09(syst.) +/- 0.04(ext.))%, showing no evidence for unobserved exclusive semielectronic modes. We combine this result with external data taken from literature to determine the ratio of the D-s(+) and D-0 semielectronic widths, Gamma(D-s(+) -> X-e(+)nu(e))/Gamma(D-0 -> X-e(+)nu(e))=0.790 +/- 0.016(stat.) +/- 0.011(syst.) +/- 0.016(ext.). Our results are consistent with and more precise than previous measurements.

摘要： Based on a data sample of (1.0087 +/- 0.0044) x 10(10) J/psi events collected by the BESIII detector at the BEPCII accelerator, the absolute branching fraction (BF) of the decay J/psi -> gamma eta is measured with high precision using events in which the radiative photon converts to e(+)e(-). Using the measured absolute BF of J/psi -> gamma eta, the absolute BFs of four dominant. decay modes are measured for the first time. The results are B(J/psi -> gamma eta) = (1.067 +/- 0.005 +/- 0.023) x 10(-3), B(eta ->gamma gamma) = (39.86 +/- 0.04 +/- 0.99)%, B(eta ->pi(0)pi(0)pi(0)) = (31.96 +/- 0.07 +/- 0.84)%, B(eta -> pi(+)pi(-)pi(0)) = (23.04 +/- 0.03 +/- 0.54)%, and B(eta -> pi(+)pi(-)gamma) = (4.38 +/- 0.02 +/- 0.10)%, where the first and second uncertainties are statistical and systematic, respectively. The results are consistent with the world average values within two standard deviations.

摘要： Based on 14.7 fb(-1) of e(+)e(-) annihilation data collected with the BESIII detector at the BEPCII collider at 17 different center-of-mass energies between 3.7730 GeV and 4.5995 GeV, Born cross sections of the two processes e(+)e(-) -> p (p) over bar eta and e(+)e(-) -> p (p) over bar omega are measured for the first time. No indication of resonant production through a vector state V is observed, and upper limits on the Born cross sections of e(+)e(-) -> p (p) over bar eta and e(+)e(-) -> p (p) over bar omega at the 90% confidence level are calculated for a large parameter space in resonance masses and widths. For the current world average parameters of the psi(4230) of m = 4.2187 GeV=c(2) and Gamma = 44 MeV, we find upper limits on resonant production of the p (p) over bar eta and p (p) over bar omega final states of 7.5 pb and 10.4 pb at the 90% CL, respectively.

摘要： Using (448.1 +/- 2.9) x 10(6) psi (3686) events collected with the BESIII detector and a single-baryon tagging technique, we present the first observation of the decays psi(3686)-> Xi (1530)(0) (Xi) over bar (1530)(0) and Xi (1530)(0) (Xi) over bar (0). The branching fractions are measured to be B psi (3686)-> Xi (1530)(0) (Xi) over bar (1530)(0)) = (6.77 +/- 0.14 +/- 0.39 x 10(- 5) and B (psi(3686)-> Xi (1530)(0) (Xi) over bar (0) = (0.53 +/- 0.04 +/- 0.03) x 10(-5). Here, the first and second uncertainties are statistical and systematic, respectively. In addition, the parameter associated with the angular distribution for the decay psi (3686) ->Xi (1530)(0) (Xi) over bar (1530)(0) is determined to be alpha= 1/4 0.32 +/- 0.19 +/- 0.07, in agreement with theoretical predictions within one standard deviation.

摘要： The absolute branching fraction of Lambda -> p mu(-)(upsilon) over bar (mu) is reported for the fast time based on an e(+)e(-) annihilation sample of 10 x 10(9) J/psi events collected with the BESIII detector at N rs = 3.097 GeV. The branching fraction is determined to be B(Lambda -> p mu(-)(upsilon) over bar (mu)). [1.48 +/- 0.21(stat) +/- 0.08(syst)] x 10(-4), which is improved by about 30% in precision over the previous indirect measurements. Combining this result with the world average of B(Lambda -> pe(-)(upsilon) over bar (e)), we obtain the ratio {[Gamma(Lambda -> p mu(-)(upsilon) over bar (mu))]/[Gamma(Lambda -> pe(-)(upsilon) over bar (e))]} to be 0.178 +/- 0.028, which agrees with the standard model prediction assuming lepton flavor universality. The asymmetry of the branching fractions of Lambda -> p mu(-)(upsilon) over bar (mu) and (Lambda) over bar -> (p) over bar mu(+)upsilon(mu) is also determined, and no evidence for CP violation is found.

摘要： By analyzing an e(+)e(-) annihilation data sample corresponding to an integrated luminosity of 2.93 fb(- 1) collected at a center-of-mass energy of 3.773 GeV with the BESIII detector, we measure the branching fraction of the D-0 ->rho(-) mu(+)nu(mu) decay for the first time. We obtain BD0 ->rho(-) mu(+)nu(mu) = (1.35 +/- 0.09(stat) +/- 0.09(syst)) x 10(-3). Using the world average of BD0 ->(rho)- epsilon(+)nu(epsilon), we find a branching fraction ratio of BD0 ->rho(-) mu(+)nu(mu)/ BD0 ->rho(-)e(+) nu(epsilon) = 0.90 +/- 0.11, which agrees with the theoretical expectation of lepton flavor universality within the uncertainty. Combining the world average of BD+->rho(0)mu+(.nu)(mu) and the lifetimes of D0(+), we obtain a partial decay width ratio of Gamma D-0 ->rho(-)mu(+)nu mu/2 Gamma D-0 ->rho(0)mu(+)nu(mu) ) = 0.71 +/- 0.14, which is consistent with the isospin symmetry expectation of unity within 2.1s. For the reported values of BD0 ->rho(-) mu(+)nu(mu)/BD0 ->rho(-)e+nu(e) and Gamma D-0 ->rho(-) mu(+nu)(mu) /2 Gamma(+)(D) ->rho(0)mu(+) nu(mu), the uncertainty is the quadratic sum of the statistical and systematic uncertainties.

摘要： In Ref.[1] the BESIII collaboration published a cross section measurement of the process e(+)e(-) -> pi(+)pi(-) in the energy range between 600 and 900 MeV. In this corrigendum, we report a corrected evaluation of the statistical errors in terms of a fully propagated covariance matrix. The correction also yields a reduced statistical uncertainty for the hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon, which now reads as a(mu)(pi pi,LO) (600 - 900 MeV) = (368.2 +/- 1.5(stat) +/- 3.3(syst)) x 10(-10). The central values of the cross section measurement and of a(mu)(pi pi,LO) , as well as the systematic uncertainties remain unchanged. (C) 2015 The Author(s). Published by Elsevier B.V.

摘要： The electromagnetic process e(+)e(-) -> p (p) over bar over bar is studied with the initial-state-radiation technique using 7.5 fb(-1) of data collected by the BESIII experiment at seven energy points from 3.773 to 4.600 GeV. The Born cross section and the effective form factor of the proton are measured from the production threshold to 3.0 GeV/c(2) using the p (p) over bar over bar invariant-mass spectrum. The ratio of electric and magnetic form factors of the proton is determined from the analysis of the proton-helicity angular distribution. (C) 2021 The Author. Published by Elsevier B.V.

摘要： A search for the charged lepton flavor violating decay J/psi -> e(+/-)tau(-/+) with tau(-/+) -> pi(-/+)pi(0)nu(tau) is performed with about 10 x 10(9) J/psi events collected with the BESIII detector at the BEPCII. No significant signal is observed, and an upper limit is set on the branching fraction B(J/psi -> e(+/-)tau(-/+)() <) 7.5 x 10(-8) at the 90% confidence level. This improves the previously published limit by two orders of magnitude.
