The New Molecular Entity Evolocumab, One Kind of PCSK9 Inhibitor, Reduce Plasma Small Size LDL-Cholesterol Levels by Using a New Standardized Method of Measuring LDL Size

引用

Open Journal of Molecular and Integrative Physiology 2017年第1期7卷 1-23页

作者： Ikuo Inoue Ryo Kubota shohan Yanagi Masumi Akita Takanari Nakano Shigehiro Katayama Akira Shimada Mistuhiko Noda Department of Endocrinology and Diabetology Saitama Medical University Saitama Japan Department of Health Sciences Saitama Prefectural University Saitama Japan Research and Development Department Advanced Materials Development Sector Tokyo Metropolitan Industrial Technology Research Institute Tokyo Japan Division of Morphological Science Biomedical Research Center Saitama Medical University Saitama Japan Department of Biochemistry Saitama Medical University Saitama Japan

Aims: There has been no evidence on the effects of evolocumab, protein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, on small size LDL. We observationally investigated the efficacy and side effects of evolocumab on the LDL subfraction particle diameter using PAGE system for lipoprotein analysis. Methods: We defined 30 patients with high-risk hyperlipidemia. As for analysis of LDL subfraction profile, we used polyacrylamide gel electrophoresis three methods: 1) 3% nondenatured poly-acrylamide gel electrophoresis method (3%PAGE), 2) 2% - 16% nondenatured poly-acrylamide gradient gel electro-phoresis method (2% - 16% GGE) and 3) 2.7% - 5% GGE. Evolocumab 140 mg/day administered together with statin significantly improved serum total cholesterol (TC), triglyceride (TG), high-dense lipoprotein-cholesterol (HDL-C), and LDL-C after four-week treatment. Results: TC, TG, HDL-C and LDL-C levels were improved by, respectively, 33%, 20%, 10%, and 54%. The mean LDL size significantly increased from 25.6 ± 0.4 nm to 26.4 ± 0.8 nm. The small dense LDL-cholesterol (sdLDL-C), large buoyant LDL-cholesterol (lbLDL-C), and mid-band lipoprotein-cholesterol were reduced, respectively. Therefore, the preliminary study on this paper can be the first step into a new insight on the world of lipid metabolism. Conclusion: Short-term administration of evolocumab addedons to statin therapy, significantly reduced small size LDL levels.

Analysis the Influenced of Plain and Twill Structures on Woven Fabric Properties

引用

Journal of Textile Science and Technology 2020年第3期6卷 107-113页

作者： Monour Khan Hasan Mahmud Tirtha Sarathi Das Muhammad Abdullah Tushar Rahman Khan Rokibul Hasan shohan Sajid Al Rafi Md Solaiman Department of Fabric Manufacturing Engineering Textile Engineering College Noakhali Affiliated by Bangladesh University of Textiles Dhaka Bangladesh Department of Wet Processing Engineering Textile Engineering College Noakhali Affiliated by Bangladesh University of Textiles Dhaka Bangladesh

Fabric outer appearance is influenced by various fabric structures. In this research work, the physical properties of plain and twill were analyzed. Physical, mechanical and other aesthetic properties are also tested and the finding results are also compared between two samples. After testing the samples it is found that rubbing fastness remains unchanged for plain and twill fabric. Abrasion resistance, pilling, crease recovery and cover factor were evaluated for twill and plain structures using ISO 12945-2, ISO 12945-1 and ISO 2313 methods respectively. Abrasion resistance and pills property are not good for twill fabric in comparison with plain fabric but crease recovery is better of twill fabric.
