Amniotic fluid and urine metabolomic alterations associated with pregnant women with Down syndrome fetuses

Xiaohang Chen, Liang Hu, Jinjiang Su, Xiaoyi Liu, Xiaojin Luo, Yuanyuan Pei, Yushan Gao & Fengxiang Wei
Down syndrome (DS) is a chromosomal disorder caused by a third copy of all or part of chromosome 21. Clinical observations and preclinical studies both suggest that DS may be associated with significant metabolic and bioenergetic alterations. But the metabolic alterations in pregnant women carrying DS fetuses still remains unclear. In this study, we investigated the characteristic metabolomics and lipidomics changes during fetal development of DS. The AF and random urine specimens were selected from...

Cell membrane-anchored anti-HIV single-chain antibodies and bifunctional inhibitors targeting the gp41 fusion protein: new strategies for HIV gene therapy

Yue Chen, Hongliang Jin, Xiaoran Tang, Li Li, Xiuzhu Geng, Yuanmei Zhu, Huihui Chong & Yuxian He
Emerging studies indicate that infusion of HIV-resistant cells could be an effective strategy to achieve a sterilizing or functional cure. We recently reported that glycosylphosphatidylinositol (GPI)-anchored nanobody or a fusion inhibitory peptide can render modified cells resistant to HIV-1 infection. In this study, we comprehensively characterized a panel of newly isolated HIV-1-neutralizing antibodies as GPI-anchored inhibitors. Fusion genes encoding the single-chain variable fragment (scFv) of 3BNC117, N6, PGT126, PGT128, 10E8, or 35O22 were constructed with...

The present study investigated the therapeutic effects of the curcumin derivative 3-[(1E)-2-(1H-indol-6-yl)ethenyl]-5-[(1E)-2-[2-methoxy-4-(2-pyridylmethoxy)phenyl]ethenyl]-1H-pyrazole (GT863) in amyotrophic lateral sclerosis (ALS). The inhibitory effect of GT863 on superoxide dismutase 1 (SOD1) aggregation was evaluated in cell-free assays. GT863 interfered with the conformational changes of the SOD1 protein and later, oligomeric aggregation. Furthermore, its antioxidant, anti-inflammatory, and neuroprotective effects were evaluated in cell-free and cultured cell assays. GT863 inhibited H2O2− and glutamate-induced cytotoxicity and activated an antioxidant responsive element...

Block-wise Variable Selection for Clustering via Latent States of Mixture Models

Beomseok Seo, Lin Lin & Jia Li
Mixture modeling is a major paradigm for clustering in statistics. In this paper, we develop a new block-wise variable selection method for clustering by exploiting the latent states of the hidden Markov model on variable blocks or the Gaussian mixture model. The variable blocks are formed by depth-first-search on a dendrogram created based on the mutual information between any pair of variables. It is demonstrated that the latent states of the variable blocks together with...

Chemical composition characteristics and source analysis of PM2.5 in Jiaxing, China: Insights into the effect of COVID-19 outbreak

Chuanfang Xiong, Yinglong Zhang, Jing Yan, Xiaoxia Yang, Qiongzhen Wang, Rui Tu & Yi He
Jiaxing is a medium-sized city in the Yangtze River Delta (YRD), which showed complex local and surrounding pollution sources. To study the COVID-19 impact on the ambient PM2.5 in Jiaxing, we collected the PM2.5 samples from January 2 to April 25, 2020 and analyzed their chemical compositions (including carbon components, water-soluble ions (WSIs), and inorganic elements). The concentration of PM2.5 was 83.13 ± 30.93 μg/m3 before COVID-19 pandemic, and then remarkably decreased with COVID-19 outbreak...

Comparison of the accelerating effect of graphene oxide and graphene on anaerobic transformation of bisphenol F by Pseudomonas sp. LS

Hong Lu, Jingyi Li, Ze Fu, Xiaolei Wang, Jiti Zhou & Jing Wang
It was found that bisphenol F (BPF) could be anaerobically transformed to 4,4-dihydroxybenzophenone using nitrate as an electron acceptor by Pseudomonas sp. LS. However, BPF removal was a slow process under anaerobic conditions. In the present study, effects of graphene oxide (GO) and graphene on the anaerobic transformation of BPF were studied in detail. Results showed that GO (2-10 mg/L) and graphene (2-20 mg/L) could increase anaerobic biotransformation rate of BPF. For GO-mediated system, GO...

Xiaoxiang Wang, Tao Lin, Wei Wu, Haisuo Wu & Dongdong Yan
The current investigation reports the synthesis of N-CDs using glucosamine, ascorbic acid, and ethylenediamine precursors by a simple hydrothermal technique. The formation of N-CDs was proved by various characterization techniques such as X-ray Photoelectron Spectroscopy (XPS), X-ray Diffraction (XRD), Transmission Electron Microscopy (TEM), and Fourier-Transform Infrared Spectrophotometer (FT-IR). The optical properties were investigated by fluorescence and UV-vis spectrophotometer. Also, N-CDs showed high selectivity in detecting the MTZ compared to several other analytes. However, the metronidazole...

Rui Zhao, Huaqiang Tao, Yuanyuan Song, Jianbo Guo, Zhi Chen, Caicai Lu, Yi Han, Haibo Li & Yanan Hou
Perchlorate (ClO4-) industrial wastewater requires efficient removal to prevent adverse environmental impacts, however, high concentration and low biodegradability give rise to poor ClO4- bioreduction performance. S2--autotrophic granular sludge (S2--AuGS) was firstly cultivated for high concentration perchlorate (ClO4-) removal in the Upflow Anaerobic Sludge Blanket (UASB) reactor (ClO4-: 150 mg·L-1). Simultaneously, the S2- was utilized to control the SO42- generation as electron donor, the effluent SO42- concentration (190 mg·L-1) was satisfied with drinking water standard (250...
