Adaptive polymorphism of tetrameric alpha-amylase inhibitors in wild emmer wheat
Ji-Rui Wang,Mei Deng,Ya-Xi Liu,Xin Qiao,Zhen-Hong Chen,Qian-Tao Jiang,Zhi-En Pu,Yu-Ming Wei,Eviatar Nevo,You-Liang Zheng 한국유전학회 2011 Genes & Genomics Vol.33 No.4
α-Amylase inhibitors are attractive candidates for the control of seed weevils as these insects are highly dependent on starch as an energy source. Wheat tetrameric α-amylase inhibitor (WTAI) is a mixture (60 kDa) of 3 units: WTAI-CM2 plus 2 WTAI-CM3 plus WTAI-CM16, where none of the subunits is active on its own. A total of 334 gene sequences were obtained from 14 populations (131 accessions= genotypes) of wild emmer wheat. The frequencies of SNPs in WTAI-CM2,WTAI-CM3 and WTAI-CM16 were 1 out of 87.6, 101.4, and 108.0 bases, where 5, 5 and 4 SNPs were detected in the coding sequence, respectively. The nucleotide sequence of each unit of tetrameric α-amylase inhibitors were much more conserved than that of dimeric or monomeric inhibitors. The wild emmer wheat populations showed diversity on three WTAI loci,both between and within populations. It was revealed that WTAI were naturally selected for across populations by a ratio of dN/dS as expected. The results of purifying and positive selection hypothesis (p<0.05) also showed that the sequences of WTAI were contributed by natural selection, which ensures the protein function conservation as well as the inhibition diversity with insects amylase enzyme. Ecological factors, singly or in combination, explained a significant proportion of the variations in the SNPs. Ecological factors have an important evolutionary role in gene differentiation at these loci, and tetrameric α-amylase inhibitors are obviously adaptively selected under different environments.

Analytical and Numerical Analysis on a New Type of Bolted Connection for Modular Steel Construction
En-Feng Deng,Jun-Yi Lian,Zhe Zhang,Zhe Liu,Ji-Jian Zhou,Shi-Quan Wang 한국강구조학회 2023 International Journal of Steel Structures Vol.23 No.4
Modular steel construction (MSC) has exhibited widespread applications in civil engineering. The inter-module connection is a key issue for the seismic performance of MSC. A detailed finite element model (FEM) of a new type of bolted connection was firstly developed. Its accuracy was validated by comparing numerical results with previous experimental results in terms of hysteretic curve and failure mode. A theoretical mechanical model was developed and its capabilities on predictions of initial rotational stiffness and ultimate moment resistance of the connection were checked through validations against test results. Further, a parametric study on several specimens with different axial load ratios, boundary conditions and section of the beams was conducted. The prediction capability of the theoretical model on seismic behavior of the connection with different beam sections was checked by comparing the skeleton curves of FEA results with theoretical ones. Subsequently, a simplified FEM was established and validated to accelerate the numerical simulation of the seismic performance of the connection.

Huang, Xin-En,Yan, Xiao-Chun,Wang, Lin,Ji, Zhu-Qing,Li, Li,Liu, Meng-Yan,Qian, Ting,Shen, Hui-Ling,Gu, Han-Gang,Liu, Yong,Gu, Ming,Deng, Li-Chun Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.17
Objective: To assess the safety and effectiveness of thalidomide (produced by CHANGZHOU PHARMACEUTICAL FACTORY CO.LTD) combined with chemotherapy in treating patients with advanced colorectal cancer. Method: A consecutive cohort of pretreated patients with advanced colorectal cancer were treated with thalidomide combined with chemotherapy. And chemotherapy for patients with advanced colorectal cancer were administered according to the condition of patients. Thalidomide was orally administered at a dosage of 50mg/day to 150mg/day before sleeping for at least 14 days. After at least 14 days of treatment, safety and side effects were evaluated. Results: There were 12 female and 3 male patients with advanced cancer recruited into this study, including 9 patients with colon, 6 patients with rectal cancer. The median age of patients was 57(41-82) years. Partial response was observed in 2 patients (2/15), and stable disease in 3 patients(3/15). Incidences of Grade 1 to 2 myelosuppression was observed in 1/15 patients, and Grade 1 to 2 elevation of hepatic enzyme was recorded in 1/15 patients. Adverse effects on the gastrointestinal tract were documented in 1/15 patients, and were Grade 1. No Grade 3-4 toxicities were diagnosed. No treatment related death was found. Conclusions: Thalidomide combined with chemotherapy was safe and mildly effective in treating patients with advanced colorectal cancer. However, further study should be conducted to clarify the effectiveness of this combination.
