Understanding the internal structures of X(4140), X(4274), X(4500) and X(4700)

Eur. Phys. J. C Hua-Xing Chen Er-Liang Cui Wei Chen Xiang Liu Shi-Lin Zhu We investigate the newly observed X (4500) and X (4700) based on the diquark-antidiquark configuration within the

Searching for hidden-charm baryonium signals in QCD sum rules

We give an explicit QCD sum rule investigation for hidden-charm baryonium states with the quark content \(u\bar{u} d\bar{d} c\bar{c}\), spin \(J=0/1/2/3\), and of both positive and negative parities. We systematically construct the relevant local hidden-charm baryonium interpolating currents, which can actually couple to various structures, including hidden-charm baryonium states, ...

QCD sum rule study of hidden-charm pentaquarks

We study the mass spectra of hidden-charm pentaquarks having spin \(J = {1\over 2}/{3\over 2}/{5\over 2}\) and quark contents \(uud c \bar{c}\). We systematically construct all the relevant local hidden-charm pentaquark currents, and we select some of them to perform QCD sum rule analyses. We find that the \(P_c(4380)\) and \(P_c(4450)\) can be identified as hidden-charm pentaquark ...

Improving the thermostability and stress tolerance of an archaeon hyperthermophilic superoxide dismutase by fusion with a unique N-terminal domain

The superoxide dismutase from the archaeon Sulfolobus solfataricus (SOD Ss ) is a well-studied hyperthermophilic SOD with crystal structure and possible thermostability factors characterized. Previously, we discovered an N-terminal domain (NTD) in a thermophilic SOD from Geobacillus thermodenitrificans NG80-2 which confers heat resistance on homologous mesophilic SODs. The present ...

Predictions of the hidden-charm molecular states with the four quark components

In this work, we study the \(T\bar{T}\)-type molecular systems systematically via the one pion exchange model, where T denotes the narrow \(J^P=1^+\) \(D_1\) meson or \(2^+\) \(D_2^*\) meson and \(\bar{T}\) is its antiparticle. With the effective potentials, we try to find the bound-state solutions of the corresponding systems, which provide crucial information of whether ...

HPV16 integration probably contributes to cervical oncogenesis through interrupting tumor suppressor genes and inducing chromosome instability

Background The integration of human papilloma virus (HPV) into host genome is one of the critical steps that lead to the progression of precancerous lesion into cancer. However, the mechanisms and consequences of such integration events are poorly understood. This study aims to explore those questions by studying high risk HPV16 integration in women with cervical intraepithelial ...

Radiative leptonic \(B_c\rightarrow \gamma \ell {\bar{\nu }}\) decay in effective field theory beyond leading order

We study the radiative leptonic \(B_c\rightarrow \gamma \ell {\bar{\nu }}\) decays in nonrelativistic QCD effective field theory, and we explore the contribution from a fast-moving photon. As a result, interactions between the photon and the heavy quarks can be integrated out, resulting in the factorization formula for the decay amplitude. We calculate not only the relevant ...

Comparative structural analysis of Bru1 region homeologs in Saccharum spontaneum and S. officinarum

Background Sugarcane is a major sugar and biofuel crop, but genomic research and molecular breeding have lagged behind other major crops due to the complexity of auto-allopolyploid genomes. Sugarcane cultivars are frequently aneuploid with chromosome number ranging from 100 to 130, consisting of 70–80 % S. officinarum, 10–20 % S. spontaneum, and 10 % recombinants between these two ...

Evaluation and clinical significance of cyclin-dependent kinase5 expression in cervical lesions: a clinical research study in Guangxi, China

Background Studies have been reported that cyclin-dependent kinase5 (CDK5) was associated with the development of several cancers. However, the relationship between CDK5 level and clinicopathological factors is still poorly understood in cervical diseases. The aim of the current study was to investigate the expression of CDK5 and its clinical significance in variant cervical ...

\(Z_c(4200)^+\) decay width as a charmonium-like tetraquark state

To identify the nature of the newly observed charged resonance \(Z_c(4200)^+\), we study its hadronic decays \(Z_c(4200)^+\rightarrow J/\psi \pi ^+, Z_c(4200)^+\rightarrow \eta _c\rho ^+\) and \(Z_c(4200)^+\rightarrow D^+\bar{D}^{*0}\) as a charmonium-like tetraquark state. In the framework of the QCD sum rules, we calculate the three-point functions and extract the coupling ...

Let-7 miRNAs Modulate the Activation of NF-κB by Targeting TNFAIP3 and Are Involved in the Pathogenesis of Lupus Nephritis

TNFAIP3 is a ubiquitin-editing enzyme that negatively regulates multiple NF-κB signaling pathways and dysregulation of TNFAIP3 is related to systemic lupus erythematosus (SLE). Although there exists evidence indicating that microRNAs (miRNAs) modulate the expression of TNFAIP3, whether and how miRNAs regulate TNFAIP3 and contribute to lupus nephritis (LN) is still not well ...

Old-Growth Platycladus orientalis as a Resource for Reproductive Capacity and Genetic Diversity

Aims Platycladus orientalis (Cupressaceae) is an old-growth tree species which distributed in the imperial parks and ancient temples in Beijing, China. We aim to (1) examine the genetic diversity and reproductive traits of old-growth and young populations of P. orientalis to ascertain whether the older populations contain a higher genetic diversity, more private alleles and a ...

Modelling optimum use of attractive toxic sugar bait stations for effective malaria vector control in Africa

Background The development of insecticide resistance and the increased outdoor-biting behaviour of malaria vectors reduce the efficiency of indoor vector control methods. Attractive toxic sugar baits (ATSBs), a method targeting the sugar-feeding behaviours of vectors both indoors and outdoors, is a promising supplement to indoor tools. The number and configuration of these ATSB ...

Prognostic Value of Tissue Inhibitor of Metalloproteinase-2 Expression in Patients with Non–Small Cell Lung Cancer: A Systematic Review and Meta-Analysis

Background and Objectives Tissue inhibitor of metalloproteinase-2 (TIMP-2) is a small secretory glycoprotein with anti–matrix metalloproteinase activity. Data on the value of TIMP-2 as a prognostic factor in non–small cell lung cancer (NSCLC) are discordant and remain controversial. A systematic review and meta-analysis was performed to explore this issue. Methods We identified the ...

Prediction of protein-protein interactions from amino acid sequences using a novel multi-scale continuous and discontinuous feature set

Background Identifying protein-protein interactions (PPIs) is essential for elucidating protein functions and understanding the molecular mechanisms inside the cell. However, the experimental methods for detecting PPIs are both time-consuming and expensive. Therefore, computational prediction of protein interactions are becoming increasingly popular, which can provide an ...

Preparation and properties of SiC honeycomb ceramics by pressureless sintering technology

SiC honeycomb ceramics with parallel channels and macroporous walls were prepared by combining extrusion molding with pressureless sintering technology in the presence of starch. The extrusion molding constructed honeycomb structure with parallel channels, while the starch formed spherical macropores on the channel walls. The density and bending strength of SiC honeycomb ceramics ...

Effectiveness of ART and Condom Use for Prevention of Sexual HIV Transmission in Serodiscordant Couples: A Systematic Review and Meta-Analysis

Background Consistent and correct condom use and suppressive antiretroviral therapy for the infected partner are two of the primary strategies recommended for prevention of heterosexual HIV transmission in serodiscordant couples today. The applied effectiveness of treatment as a prevention strategy in China is still under investigation, and much less is known about its effects in ...
