β-galactosidase GALA from Bacillus circulans with high transgalactosylation activityYaru 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...

Study on the working mechanism of fluid loss additive for chlorination titanium blast furnace slagPing Zhou, Yuanpeng Wu, Huiting Liu, Ming Li, Weiyuan Xiao, Meng Liu, Jianzhang Hao, Yanming Li & Chengxin Li
The chlorination titanium blast furnace slag belongs to industrial waste, but after grinding, they can be used to prepare cementing fluids to realize the secondary utilization of solid waste resources. As a common additive, fluid loss additives are mostly used in oil well cement systems, and there is still a lot of room for development when applied to chlorination titanium blast furnace slag systems. In this paper, the AMPS/DN-1/DMC/AA tetramer fluid loss additive was synthesized...
Co-delivery of paclitaxel (PTX) and docosahexaenoic acid (DHA) by targeting lipid nanoemulsions for cancer therapyBo Li, Tingfei Tan, Weiwei Chu, Ying Zhang, Yuanzi Ye, Shanshan Wang, Yan Qin, Jihui Tang & Xi Cao
Breast cancer is one of the most common types of cancer in female patients with high morbidity and mortality. Multi-drug chemotherapy has significant advantages in the treatment of malignant tumors, especially in reducing drug toxicity, increasing drug sensitivity and reducing drug resistance. The objective of this research is to fabricate lipid nanoemulsions (LNs) for the co-delivery of PTX and docosahexaenoic acid (DHA) with folic acid (FA) decorating (PTX/DHA-FA-LNs), and investigate the anti-tumor activity of the...
A new cyclopentenone derivative from Trichoderma atroviride HH-01Li Zhu, Jia-Peng Wang, Feng Hao, Dong Gan, Xiao-Ran Zhang, Chen-Zhe Li, Cheng-Yao Wang, Liang Zhang & Le Cai
A new cyclopentenone derivative, atrovinol (1), together with ten known compounds (2-11) were isolated from Trichoderma atroviride HH-01, an endophytic fungus from Illigera rhodantha (Hernandiaceae). Their structures were identified by HRESIMS, 1 D/2D NMR, and electronic circular dichroism (ECD) spectra. Compound 1 exhibited moderate inhibitory activity against Staphylococcus aureus and Bacillus subtilis with MIC values of 8.0 µg/mL and 16.0 µg/mL, respectively.
MiR-3138 deteriorates the insulin resistance of HUVECs via KSR2/AMPK/GLUT4 signaling pathwayYan Chen, Da Lin, Changxuan Shi, Liang Guo, Linhua Liu, Lin Chen, Ting Li, Ying Liu, Chengchao Zheng, Xintong Chi, Chun Meng & Yaoming Xue
Insulin resistance (IR) is a complex pathological condition resulting from the dysregulation of cellular response to insulin hormone in insulin-dependent cells and is recognized as a pathogenic hallmark and strong risk factor for metabolic syndrome. The present study aims to elucidate the molecular mechanism of the pathogenesis of IR. Here, we used human umbilical vein endothelial cells (HUVECs) to establish the IR cell model induced by 1 × 10−6 mmol/L insulin. After 48 h, reactive...

Autophagy induced by Vip3Aa has a pro-survival role in Spodoptera frugiperda Sf9 cellsXiaoyue Hou, Lu Han, Baoju An & Jun Cai
Vip3Aa is an insecticidal protein that can effectively control certain lepidopteran pests and has been used widely in biological control. However, the mechanism of action of Vip3Aa is unclear. In the present study, we showed that Vip3Aa could cause autophagy in Sf9 cells, which was confirmed by the increased numbers of GFP-Atg8 puncta, the appearance of autophagic vacuoles, and an elevated Atg8-II protein level. Moreover, we found that the AMPK-mTOR-ULK1 pathway is involved in Vip3Aa-induced...

Rice straw is one of the major agricultural residues that is generated enormously in Asian countries. Thus, it is critical to develop an efficient process of converting this residue into valuable compounds in replacing fossil-based products. Herein, we developed an economically viable cement catalyst to pyrolyze the rice straw into bio-oil and fuel gas in a batch-type reactor. Under the optimized conditions, the maximum bio-oil yield of 41.07 wt.%, and gas yield of 30.53 wt.%...
Identification of the structural features of quinazoline derivatives as EGFR inhibitors using 3D-QSAR modeling, molecular docking, molecular dynamics simulations and free energy calculationsFangfang Wang, Wei Yang, Hongping Liu & Bo Zhou
Epidermal growth factor receptor (EGFR) is a promising target for the treatment of different types of malignant tumors. Therefore, a combined molecular modeling study was performed on a series of quinazoline derivatives as EGFR inhibitors. The optimum ligand-based CoMFA and CoMSIA models showed reliable and satisfactory predictability (with R2cv=0.681, R2ncv=0.844, R2pred=0.8702 and R2cv=0.643, R2ncv=0.874, R2pred=0.6423). The derived contour maps provide structural features to improve inhibitory activity. Furthermore, the contour maps, molecular docking, and molecular dynamics...
Ensemble and calibration multiply robust estimation for quantile treatment effectXiaohong He & Lei Wang
Quantile treatment effects can be important causal estimands in the evaluation of biomedical treatments or interventions for health outcomes such as birthweight and medical cost. However, the existing estimators require either a propensity score model or a conditional density vector model is correctly specified, which is difficult to verify in practice. In this paper, we allow multiple models for propensity score and conditional density vector, then construct a class of calibration estimators based on multiple...
Carbonized rice husk coated solar absorber for clean water generation from seawater with a solar stillWong Min Jin Karen, C. Y. Wong, Zhipeng Wang, Willey Y. H. Liew & G. J. H. Melvin
This study demonstrated the generation of clean water from seawater collected at the beach coast in Universiti Malaysia Sabah, Malaysia, with carbonized rice husk coated melamine sponge as solar absorber by a solar still. Melamine sponge was utilized as a seawater transportation medium since its porous structure is excellent in channelling the seawater. Whereas carbonized rice husk was used as the photothermal conversion material for its efficient heat absorption due to its black colour and...

Surra, one of the most important animal diseases with economic consequences in Asia and South America, is caused by Trypanosoma evansi. However, the mechanism of immune evasion by T. evansi has not been extensively studied. In the present study, T. evansi extracellular vesicles (TeEVs) were characterized and the role of TeEVs in T. evansi infection were examined. The results showed that T. evansi and TeEVs could activate TLR2-AKT pathway to inhibit the secretions of IL-12p40,...

A novel genetic variant potentially altering the expression of MANBA in the cerebellum associated with attention deficit hyperactivity disorder in Han Chinese childrenXinzhen Chen, Ting Yao, Jinliang Cai1, Qi Zhang, Shanyawen Li, Huiru Li, Xihang Fu & Jing Wu
To get additional insight into the genetic factors of attention deficit hyperactivity disorder (ADHD). First, we performed a transcriptome-wide association study (TWAS) integrating human cerebellum-specific variant-expression/splicing correlations to identify ADHD susceptibility genes. Then, the associations between expression/splicing quantitative trait loci (eQTLs/sQTLs) of the transcriptome-wide significant genes and ADHD were observed in a case-control study of Han Chinese children. Furthermore, dual luciferase reporter gene assays were performed to validate the regulatory function of ADHD risk variants....

Single-machine scheduling with energy generation and storage systemsHyun-Jung Kim, Eun-Seok Kim, Jun-Ho Lee, Lixin Tang & Yang Yang
This paper considers a single-machine scheduling problem with sequence-dependent setup times and energy-generation and storage systems. Each job requires a sequence-dependent setup to be processed on the machine, and both setup and processing of the job require job-dependent amounts of energy. The energy consumed by the machine can be bought from an Electric Power Company (EPC) or generated by own Distributed Energy Resource (DER), such as solar photovoltaic or wind, and the energy can be...
