Suppression of complement component 2 expression by hepatitis B virus contributes to the viral persistence in chronic hepatitis B patients

Gang Ning, Li‐Min Zhen, Wen‐Xiong Xu, Xue‐Jun Li, more

Journal of Viral Hepatitis > 27 > 10 > 1071 - 1081

Previously, we identified rare missense mutations of complement component 2 (C2) to be associated with chronic hepatitis B (CHB) by exome sequencing. However, up to now, little is known about the role of C2 in CHB. In the present study, we aimed to perform preliminary exploration about the underlying role of C2 in CHB. Serum samples from 113 CHB patients and 30 healthy controls, and liver biopsy samples...

Materials & Design > 2017 > 126 > C > 135-140

A series of plastic items with anisotropic heat and resistance distribution were prepared by 3D printing. Conductive graphene doped polylactic acid (G-PLA) and pure PLA were used as raw materials. The programmed mixing printing method was adopted to construct these objects. The effects of the extrusion ratios of G-PLA and PLA, applied voltage and heat distribution on the printed items were investigated...

Use of low-dose computed tomography to assess pulmonary tuberculosis among healthcare workers in a tuberculosis hospital

Wei He, Bu-Dong Chen, Yan Lv, Zhen Zhou, more

Infectious Diseases of Poverty > 2017 > 6 > 1 > 1-10

Background According to the World Health Organization, China is one of 22 countries with serious tuberculosis (TB) infections and one of the 27 countries with serious multidrug-resistant TB strains. Despite the decline of tuberculosis in the overall population, healthcare workers (HCWs) are still at a high risk of infection. Compared with high-income countries, the TB prevalence among HCWs is higher...

Resonant photoelectron imaging of deprotonated uracil anion via vibrational levels of a dipole-bound excited state

Dao-Ling Huang, Hong-Tao Liu, Chuan-Gang Ning, Phuong Diem Dau, more

Chemical Physics > 2017 > 482 > C > 374-383

radical are obtained, including all eight low-frequency out-of-plane modes, which are forbidden in non-resonant photoelectron spectroscopy. Furthermore, the breakdown of the Δv=−1 propensity rule is observed for autodetachment from many vibrational levels of the dipole-bound state, due to anharmonic effects. In particular, we have observed intramolecular electron rescattering in a number of resonant...

Activation of Methane Promoted by Adsorption of CO on Mo₂C₂⁻ Cluster Anions

Qing‐Yu Liu, Jia‐Bi Ma, Zi‐Yu Li, Chongyang Zhao, more

Angewandte Chemie > 128 > 19 > 5854 - 5858

Atomic clusters are being actively studied for activation of methane, the most stable alkane molecule. While many cluster cations are very reactive with methane, the cluster anions are usually not very reactive, particularly for noble metal free anions. This study reports that the reactivity of molybdenum carbide cluster anions with methane can be much enhanced by adsorption of CO. The Mo₂C₂⁻ is inert...

In vitro and in vivo correlates of physiological and neoplastic human Fallopian tube stem cells

Yusuke Yamamoto, Gang Ning, Brooke E Howitt, Karishma Mehra, more

The Journal of Pathology > 238 > 4 > 519 - 530

High‐grade serous cancer (HGSC) progresses to advanced stages without symptoms and the 5‐year survival rate is a dismal 30%. Recent studies of ovaries and Fallopian tubes in patients with BRCA1 or BRCA2 mutations have documented a pre‐metastatic intramucosal neoplasm that is found almost exclusively in the Fallopian tube, termed ‘serous tubal intraepithelial carcinoma’ or STIC. Moreover, other proliferations,...

Nanoscale precipitates and comprehensive strengthening mechanism in AISI H13 steel

Wen-wen Mao, An-gang Ning, Han-jie Guo

International Journal of Minerals, Metallurgy, and Materials > 2016 > 23 > 9 > 1056-1064

The effects of heat treatment on the precipitates and strengthening mechanism in AISI H13 steel were investigated. The results showed that the presence of nanoscale precipitates favorably affected grain refinement and improved the yield strength. The volume fraction of precipitates increased from 1.05% to 2.85% during tempering, whereas the average precipitate size first decreased then increased during...

CH Bond Activation by Early Transition Metal Carbide Cluster Anion MoC₃⁻

Zi‐Yu Li, Lianrui Hu, Qing‐Yu Liu, Chuan‐Gang Ning, more

Chemistry – A European Journal > 21 > 49 > 17748 - 17756

Although early transition metal (ETM) carbides can activate CH bonds in condensed‐phase systems, the electronic‐level mechanism is unclear. Atomic clusters are ideal model systems for understanding the mechanisms of bond activation. For the first time, CH activation of a simple alkane (ethane) by an ETM carbide cluster anion (MoC₃⁻) under thermal‐collision conditions has been identified by using...

Research of photonic-assisted triangular-shaped pulses generation based on quadrupling RF modulation

Jin Yuan, Ti-gang Ning, Jing Li, Yue-qin Li, more

Optoelectronics Letters > 2015 > 11 > 3 > 207-212

We propose an approach to generate optical triangular-shaped pulse train with tunable repetition rate using quadrupling radio frequency (RF) modulation and optical grating dispersion-induced power fading. In this work, a piece of chirped fiber Bragg grating (FBG) is employed as the dispersive media to remove the undesired 8th harmonic in optical intensity. Thus, the generated harmonics of optical...

The PAX2‐null immunophenotype defines multiple lineages with common expression signatures in benign and neoplastic oviductal epithelium

Gang Ning, Jonathan G Bijron, Yusuke Yamamoto, Xia Wang, more

The Journal of Pathology > 234 > 4 > 478 - 487

The oviducts contain high‐grade serous cancer (HGSC) precursors (serous tubal intraepithelial neoplasia or STINs), which are γ‐H2AX^p‐ and TP53 mutation‐positive. Although they express wild‐type p53, secretory cell outgrowths (SCOUTs) are associated with older age and serous cancer; moreover, both STINs and SCOUTs share a loss of PAX2 expression (PAX2ⁿ). We evaluated PAX2 expression in proliferating...

Firework injuries at a major trauma and burn center: A five-year prospective study

Cheng Wang, Ran Zhao, Wei-Li Du, Fang-Gang Ning, more

Burns > 2014 > 40 > 2 > 305-310

In China, fireworks are an integral part of the celebration of the annual Spring Festival, but the number of injuries associated with their private use seen in emergency rooms increases dramatically. To raise awareness and help guide future prevention practices in this city, we investigated the epidemiology of firework-related injuries presented at our trauma and burn center in Beijing during the...

Vibrational Spectroscopy of the Dehydrogenated Uracil Radical by Autodetachment of Dipole‐Bound Excited States of Cold Anions

Hong‐Tao Liu, Chuan‐Gang Ning, Dao‐Ling Huang, Lai‐Sheng Wang

Angewandte Chemie > 126 > 9 > 2496 - 2500

Molecules with large enough dipole moments can bind an electron by the dipole field, which has little effect on the molecular core. A molecular anion can be excited to a dipole‐bound state, which can autodetach by vibronic coupling. Autodetachment spectroscopy of a complex anion cooled in a cryogenic ion trap is reported. Vibrational spectroscopy of the dehydrogenated uracil radical is obtained by...

Through the glass darkly: intraepithelial neoplasia, top‐down differentiation, and the road to ovarian cancer

Christopher P Crum, Michael Herfs, Gang Ning, Jonathan G Bijron, more

The Journal of Pathology > 231 > 4 > 402 - 412

It is currently hoped that deaths from extra‐uterine high‐grade serous cancer (HGSC) will be reduced via opportunistic salpingectomy in healthy women. Accumulated data implicate the fimbria as a site of origin and descriptive molecular pathology and experimental evidence strongly support a serous carcinogenic sequence in the Fallopian tube. Both direct and indirect (‘surrogate’) precursors suggest...

Ying-kun Guo, Zhi-gang Yang, Heng Shao, Wen Deng, more

International Journal of Cardiology > 2013 > 167 > 4 > 1585-1590

This study prospectively compared the accuracy of a sixty-four slice multidetector row CT (64-MDCT) in cardiac magnetic resonance imaging (MRI) for the assessment of right ventricular (RV) dysfunction and dilatation in patients with mitral regurgitation.Eighty-four patients underwent ECG-gated 64-MDCT for the assessment of RV dysfunction and dilatation; 54 of these patients had known mitral regurgitation...
