Two-Directional Simultaneous Inference for High-Dimensional Models

Wei Liu, Huazhen Lin, Jin Liu & Shurong Zheng
This article proposes a general two-directional simultaneous inference (TOSI) framework for high-dimensional models with a manifest variable or latent variable structure, for example, high-dimensional mean models, high-dimensional sparse regression models, and high-dimensional latent factors models. TOSI performs simultaneous inference on a set of parameters from two directions, one to test whether the assumed zero parameters indeed are zeros and one to test whether exist zeros in the parameter set of nonzeros. As a result, we...

Over one billion people have received 2–3 dosages of an inactivated COVID-19 vaccine for basic immunization. Whether a booster dose should be delivered to protect against the Omicron variant and its sub-lineages, remains controversial. Here, we tested different vaccine platforms targeting the ancestral or Omicron strain as a secondary booster of the ancestral inactivated vaccine in mice. We found that the Omicron-adapted inactivated viral vaccine promoted a neutralizing antibody response against Omicron in mice. Furthermore,...

Xinhui Wang, Xue Liu, Jie Yuan, Huizhi Zhou, Yuyao Wang, Guoyu Tian, Xueying Liu, Mulin Tang, Xue Meng, Yuchen Li, Yuwei Chai, Chunjia Kou, Qingqing Yang, Juyi Li, Li Zhang & Haiqing Zhang
The role of thyroid hormones in tumors has been discussed in observational studies; however, the causal relationship between them remains controversial. Six different Mendelian randomization (MR) Methods, including Inverse variance weighted (IVW), MR-Egger, Simple mode, MR-Pleiotropy Residual Sum and Outlier methods (MR-PRESSO), Weighted mode and Weighted median were used to Two-Sample MR analysis. Our research shows that hypothyroidism genetically has a protective causal association with lung cancer.

Feng Fan, Xin Zhang, Zhiyu Zhang, Yuan Ding, Limei Wang, Xin Xu, Yaying Pan, Fang-Yuan Gong, Lin Jiang, Lingyu Kang, Zhuo Ha, Huijun Lu, Jiawang Hou, Zhihua Kou, Gan Zhao, Bin Wang & Xiao-Ming Gao
Breakthrough infections by SARS-CoV-2 variants pose a global challenge to COVID-19 pandemic control, and the development of more effective vaccines of broad-spectrum protection is needed. In this study, we constructed pVAX1-based plasmids encoding receptor-binding domain (RBD) chimera of SARS-CoV-1 and SARS-CoV-2 variants, including pAD1002 (encoding RBDSARS/BA1), pAD1003 (encoding RBDSARS/Beta) and pAD131 (encoding RBDBA1/Beta). Plasmids pAD1002 and pAD131 were far more immunogenic than pAD1003 in terms of eliciting RBD-specific IgG when intramuscularly administered without electroporation. Furthermore,...

Orthogonal dual reporter-based gain-of-signal assay for probing SARS-CoV-2 3CL protease activity in living cells: inhibitor identification and mutation investigation

Zhu-Chun Beia, Huanhuan Yu, Hong Wang, Qingyun Li, Baogang Wang, Dongna Zhang, Likun Xu, Liangliang Zhao, Shuwei Dong & Yabin Song
The main protease (3-chymotrypsin-like protease, 3CLpro) of SARS-CoV-2 has become a focus of anti-coronavirus research. Despite efforts, drug development targeting 3CLpro has been hampered by limitations in the currently available activity assays. Additionally, the emergence of 3CLpro mutations in circulating SARS-CoV-2 variants has raised concerns about potential resistance. Both emphasize the need for a more reliable, sensitive, and facile 3CLpro assay. Here, we report an orthogonal dual reporter-based gain-of-signal assay for measuring 3CLpro activity in...

Shuai Mao, Lei Wang, Peipei Chen, Yong Lan, Rui Guo & Minzhou Zhang
Our previous works have shown that tanshinone IIA inhibited maladaptive extracellular matrix remodeling in cardiac fibroblasts implicating its potential role in treating of pathologic cardiac remodeling. However, the intrinsically poor solubility and bioavailability of tanshinone IIA hindered its clinical application. Here we develop monomethoxy-poly (ethylene glycol)-poly (lactic acid)-D-α-Tocopheryl polyethylene glycol 1000 succinate (mPEG-PLA-TPGS) nanoparticle incorporating tanshinone IIA (tanshinone IIA-NPs) and study its efficacy in post-infarction left ventricular (LV) remodeling. Male C57BL/6 mice underwent left coronary...

Daidzein stimulates fatty acid-induced fat deposition in C2C12 myoblast cells via the G protein-coupled receptor 30 pathway

Chengjian Zhou, Ping Li, Meihong Han & Xuejun Gao
Fat deposition in skeletal muscle is an important aspect of improving meat quality. Isoflavones can promote animal anabolism, but whether and how they regulate muscle fat deposition remain largely unclear. In this study, we explored the role and corresponding molecular mechanism of one of the major isoflavones, daidzein, in fat deposition in C2C12 myoblast cells. In the absence of fatty acids (FAs), daidzein did not promote triglyceride synthesis and lipid droplet formation in cells but...

Comparisons on fluid-solid heat transfer simulation for localized fire resistance

Xuanyi Zhou, Jinggang Zhou, Beihua Cong & Wei Wang
A research idea of multi-physics field coupling can be used to solve the structural fire resistance problem. Most of the previous CFD-FEM numerical simulations in structural fire resistance studies apply adiabatic surface temperature (AST) to accurately describe the complex fire analysis boundary conditions, and this methodology belongs to the use of iterative coupling methods to achieve fluid-solid heat transfer coupling. However, there is less application for another direct two-way coupling method. In this paper, a...

Meng Li, Liping Lu, Mingcheng Guo, Qi Jiang, Lan Xia, Yuan Jiang, Shu Zhang, Yong Qiu, Chongguang Yang, Yiwang Chen, Jianjun Hong, Xiaoqin Guo, Howard Takiff, Xin Shen, Chuang Chen & Qian Gao
The fitness of multidrug-resistant tuberculosis (MDR-TB) is thought to be an important determinant of a strain’s ability to be transmitted and cause outbreaks. Studies in the laboratory have demonstrated that MDR-TB strains have reduced fitness but the relative transmissibility of MDR-TB versus drug-susceptible (DS) TB strains in human populations remains unresolved. We used data on genomic clustering from our previous molecular epidemiological study in Songjiang (2011-2020) and Wusheng (2009-2020), China, to compare the relative transmissibility...

The re-emerging mpox (formerly monkeypox) virus (MPXV), a member of Orthopoxvirus genus together with variola virus (VARV) and vaccinia virus (VACV), has led to public health emergency of international concern since July, 2022. Inspired by the unprecedent success of coronavirus disease 2019 (COVID-19) mRNA vaccines, the development of a safe and effective mRNA vaccine against MPXV is of high priority. Based on our established lipid nanoparticle (LNP)-encapsulated mRNA vaccine platform, we rationally constructed and prepared...

Pingchao Li, Qian Wang, Yizi He, Chenchen Yang, Zhengyuan Zhang, Zijian Liu, Bo Liu, Li Yin, Yilan Cui, Peiyu Hu, Yichu Liu, Pingqian Zheng, Wei Wang, Linbing Qu, Caijun Sun, Suhua Guan, Liqiang Feng & Ling Chen
Prolonged infection and possible evolution of SARS-CoV-2 in patients living with uncontrolled HIV-1 infection highlight the importance of an effective vaccination regimen, yet the immunogenicity of COVID-19 vaccines and predictive immune biomarkers have not been well investigated. Herein, we report that the magnitude and persistence of antibody and cell-mediated immunity (CMI) elicited by an Ad5-vectored COVID-19 vaccine are impaired in SIV-infected macaques with high viral loads (> 105 genome copies per ml plasma, SIVhi) but...
