Jing Zhan, Sen Ma, Xiao‐Xi Wang, Li Li, more

International Journal of Food Science & Technology > 54 > 10 > 2839 - 2846

The effect of baked wheat germ (BWG) on the gluten network structure in steam bread dough was investigated. The secondary structure, free sulphydryl (‐SH) content, disulphide (‐SS‐) bonds content and microstructure of gluten were analysed to evaluate gluten structural changes. The addition of different amounts of BWG (0, 2, 4, 6, 8, 10, and 12%) in dough resulted in decreased content of α‐helix and...

Zhi-da Zhang, Hui Ren, Wei-xi Wang, Geng-yang Shen, more

Journal of Zhejiang University-SCIENCE B > 2019 > 20 > 10 > 838-848

Insulin-like growth factor-1 receptor (IGF-1R) is involved in both glucose and bone metabolism. IGF-1R signaling regulates the canonical Wnt/β-catenin signaling pathway. In this study, we investigated whether the IGF-1R/ β-catenin signaling axis plays a role in the pathogenesis of diabetic osteoporosis (DOP). Serum from patients with or without DOP was collected to measure the IGF-1R level using enzyme-linked...

Ruobi Hu, Hui Li, Zhen Lei, Qing Han, more

Biotechnology and Bioengineering > 116 > 10 > 2652 - 2661

A pyrogen test is crucial for evaluating the safety of drugs and medical equipment, especially those involved in injections. As existing pyrogen tests, including the rabbit pyrogen test, the limulus amoebocyte lysate (LAL) test and the monocyte activation test have limitations, development of new models for pyrogen testing is necessary. Here we develop a sensitive cell model for pyrogen test based...

Long Chen, Junquan Dong, Fu-Xi Wang, Shihu Gao, more

Soil Mechanics and Foundation Engineering > 2019 > 56 > 3 > 210-216

To study the performance of a sheet-pile wall reinforcing an old gravity revetment, a 3-m-deep excavation was carried out in front of a 10-m-long sheet-pile wall. The excavation was simulated by finite-element modelling and the results were compared with field measurement. The reinforcing sheet-pile wall showed good performance. When the excavation depth was less than 1.2 m the old revetment inhibited...

Multitask learning for biomedical named entity recognition with cross-sharing structure

Xi Wang, Jiagao Lyu, Li Dong, Ke Xu

BMC Bioinformatics > 2019 > 20 > 1 > 1-13

Background Biomedical named entity recognition (BioNER) is a fundamental and essential task for biomedical literature mining, which affects the performance of downstream tasks. Most BioNER models rely on domain-specific features or hand-crafted rules, but extracting features from massive data requires much time and human efforts. To solve this, neural network models are used to automatically learn...

Jing Yan, Jian‐Yun Yan, Yu‐Xi Wang, Yuan‐Na Ling, more

British Journal of Pharmacology > 176 > 17 > 3126 - 3142

Background and Purpose Spermidine, a natural polyamine, is abundant in mammalian cells and is involved in cell growth, proliferation, and regeneration. Recently, oral spermidine supplements were cardioprotective in age‐related cardiac dysfunction, through enhancing autophagic flux. However, the effect of spermidine on myocardial injury and cardiac dysfunction following myocardial infarction (MI)...

HOXB13 promotes proliferation, migration, and invasion of glioblastoma through transcriptional upregulation of lncRNA HOXC‐AS3

Xi Wang, Yi Sun, Tuoye Xu, Kai Qian, more

Journal of Cellular Biochemistry > 120 > 9 > 15527 - 15537

HOXB13 exerts a close relation in several human cancers. This study explored the role of HOXB13 in glioblastoma (GBM), a brain tissue with the highest aggressive rate and mortality in adults. Through microarray and immunohistochemistry analyses, HOXB13 was highly expressed in GBM tissues. Furthermore, we showed that high‐level expression of HOXB13 in GBM was associated with worse survival, suggesting...
