New SARS-CoV-2 mutants have been continuously indentified with enhanced transmission ever since its outbreak in early 2020. As an RNA virus, SARS-CoV-2 has a high mutation rate due to the low fidelity of RNA polymerase. To study the single nucleotide polymorphisms (SNPs) dynamics of SARS-CoV-2, 158 SNPs with high confidence were identified by deep meta-transcriptomic sequencing, and the most common SNP type was C > T. Analyses of intra-host population diversity revealed that intra-host quasispecies’...

Furthermore, this is the first study to apply the spatial econometric models with a geographical distance matrix to investigate the local and spatial spillover effects of environmental regulations on heterogeneous environmental governance performance (i.e. clean production and end-of-pipe treatment performances). The results...

Identification of fibronectin 1 (FN1) and complement component 3 (C3) as immune infiltration-related biomarkers for diabetic nephropathy using integrated bioinformatic analysis

Yuejun Wang, Mingming Zhao & Yu Zhang
Immune cell infiltration (ICI) plays a pivotal role in the development of diabetic nephropathy (DN). Evidence suggests that immune-related genes play an important role in the initiation of inflammation and the recruitment of immune cells. However, the underlying mechanisms and immune-related biomarkers in DN have not been elucidated. Therefore, this study aimed to explore immune-related biomarkers in DN and the underlying mechanisms using bioinformatic approaches. In this study, four DN glomerular datasets were downloaded, merged,...

S-adenosyl-L-homocysteine hydrolase FgSah1 is required for fungal development and virulence in Fusarium graminearum

Dongya Shi, Yu Zhang, Jin Wang, Weichao Ren, Jie Zhang, Jane Ifunanya Mbadianya, Yuanye Zhu, Changjun Chen & Hongyu Ma
The S-adenosyl-L-homocysteine hydrolase (Sah1) plays a crucial role in methylation and lipid metabolism in yeast and mammals, yet its function remains elusive in filamentous fungi. In this study, we characterized Sah1 in the phytopathogenic fungus F. graminearum by generating knockout and knockout-complemented strains of FgSAH1. We found that the FgSah1-GFP fusion protein was localized to the cytoplasm, and that deletion of FgSAH1 resulted in defects in vegetative growth, asexual and sexual reproduction, stress responses, virulence,...

Cerclage placement in twin pregnancies with cervical dilation: a systematic review and meta-analysis

Jingjing Su, Dan Li, Yuanyuan Yang, Yunxia Cao & Zongzhi Yin
Existing guidelines and studies on the benefits of cerclage in twin pregnancies with a dilated cervix have low reliability and inconsistent conclusions. New randomized control trials and cohort studies focusing on twin pregnancies with cervical insufficiency were published recently. Therefore, this meta-analysis aimed to compare outcomes of cerclage placement and expectant treatment in twin pregnancies with a dilated cervix using recent data. We screened the PubMed, Web of Science, ClinicalTrials.gov, and Cochrane Library databases to...

A ten-faced hexangulaconulariid from Cambrian Stage 2 of South China

Junfeng Guo, Jian Han, Heyo Van Iten, Zuchen Song, Yaqin Qiang, Wenzhe Wang, Zhifei Zhang & Guoxiang Li
Hexangulaconulariids (Cambrian stages 1‒2) are an extinct group of medusozoan polyps having a biradially symmetrical, fan-shaped periderm that is distinct from those of medusozoan polyps showing three-, four-, five-, or six-fold radial symmetry. Hexangulaconulariids exhibit substantial variation in gross morphology, including variation in the number of faces on each of the two major sides of the periderm. An intermediate taxon of hexangulaconulariids with ten faces (five on each major side) was expected. Here we describe...

Using a WeChat mini-program-based lactation consultant intervention to increase the consumption of mother’s own milk by preterm infants in the neonatal intensive care unit: a study protocol for a cluster randomized controlled trial

Jie Huo, Xinping Wu, Chuanli Gu, Zhangbin Yu, Jun Zhang, Xiaohui Chen, Jingai Zhu, Feng Liu, Beibei Liu, Qianqian Li & Shuping Han
Abstract Background The benefits of mother’s own milk (MOM) for preterm infants have been widely recognized. Many studies have shown that the rate of breastfeeding of premature infants remains very low. Although many studies use measures to promote breastfeeding, few high-quality cluster randomized controlled studies have evaluated the effectiveness of these measures. WeChat is an instant messaging software for smart terminals, and WeChat mini-programs have been widely used to promote health and self-management in China....

Maggie Mengqing Zhang, Xiao Wang & Yang Hu
Drawing upon the approach of strategic framing, this study investigated how China’s state-run media mobilize foreign propaganda machine and use specific patterns to describe the 2019 Hong Kong protests on Twitter. It also shed light on the heterogeneity of both production and reception of the strategic frames used by state media. Structural topic modeling was employed to analyze a large amount of Twitter content (i.e., 14,412 tweets) posted by 13 verified organizational accounts, and six...

Novel mutation in TSPAN12 associated with familial exudative vitreoretinopathy in a Chinese pedigree

Zhen Song, Mo Li, Chang Wang, Yu Wang, Lihua Zhang, Na Li, Ruifang Yang & Ping Sun
Familial exudative vitreoretinopathy (FEVR) is a rare retinal disorder characterised by incomplete retinal vascular development. Symptoms vary widely from none to blindness even within the same family. Multiple genes related to the Wnt pathway have been found to be associated with FEVR. Recent studies identified tetraspanin 12 (TSPAN12) as a cause of the autosomal dominant inheritance form of FEVR. Here, we describe a novel TSPAN12 mutation in a Chinese family with FEVR. Targeted next-generation sequencing...

β-galactosidase GALA from Bacillus circulans with high transgalactosylation activity

Yaru Yan, Weishi Guan, Xiaoyi Li, Kaier Gao, Xinxin Xu, Bo Liu, Wei Zhang & Yuhong Zhang
β-galactosidase catalyzes lactose hydrolysis and transfers reactions to produce prebiotics such as galacto-oligosaccharides (GOS) with potential applications in the food industry and pharmaceuticals. However, there is still a need for improved transgalactosylation activity of β-galactosidases and reaction conditions of GOS production in order to maximize GOS output and reduce production costs. In this study, a β-galactosidase gene, galA, from Bacillus circulans was expressed in Pichia pastoris, which not only hydrolyzed lactose but also had strong...
