Biodegradable hydrogels are promising biomaterials for use in controlled-release systems for skin tissue regeneration. Controlled delivery systems constitute an important aspect of tissue engineering because they can modulate various physiological responses, including early immune response, tissue remodeling, and cell proliferation and maturation in the wound-healing process. Hydrogels composed of various biomaterials have been developed to overcome the limitations of conventional drug- or protein-delivery systems, such as limited targeting ability, low stability, and the induction of drug resistance. Hydrogels based on keratin, a natural polymer extracted from human hair, can provide adequate cell support and control homeostasis. Consequently, they can be applied for skin tissue engineering. In this study, we prepared degradable, tunable, and biocompatible hydrogels for controllable protein delivery. We synthesized keratin-fibrinogen (KER-FBG) by the chemical coupling reaction and prepared hydrogels through polymerization with thrombin. The structures and morphologies of the KER-FBG hydrogels were confirmed. Furthermore, the mechanical properties, swelling ratio, degradation, release behavior, and biocompatibility were investigated. The KER-FBG hydrogels presented promising biological performance, indicating that the material is suitable as a controlled protein delivery carrier.

Role of two-dimensional shear wave elastography in chronic liver diseases: A narrative review

World Journal of Gastroenterology 2018年第34期24卷 3849-3860页

Liver biopsy is the gold standard for evaluating the degree of liver fibrosis in patients with chronic liver disease. However, due to the many limitations of liver biopsy, there has been much interest in the use of noninvasive techniques for this purpose. Among these techniques real-time two-dimensional shear wave elastography(2D-SWE) has the advantage of measuring tissue elasticity with the guidance of B-mode images. Recently, many studies have been conducted on the application of 2D-SWE in patients with various liver diseases, and their validity has been confirmed. Here, we briefly discuss the role of 2D-SWE in patients with chronic liver diseases, particularly aspects of the examination techniques and clinical applications.

Strong association of regulatory single nucleotide polymorphisms (SNPs) of the IFITM3 gene with influenza H1N1 2009 pandemic virus infection

引用

Cellular & Molecular Immunology 2020年第6期17卷 662-664页

作者： Yong-Chan Kim min-Ju jeong Byung-Hoon jeong Korea Zoonosis Research Institute Chonbuk National UniversityIksanJeonbuk 54531Republic of Korea Department of Bioactive Material Sciences Chonbuk National UniversityJeonjuJeonbuk 54896Republic of Korea

The IFITM3 gene is classified as a member of the small interferonstimulated genes(ISGs)and plays a paramount role in defense against enveloped viruses,including influenza A viruses.1–6 Previous studies have reported that the rs12252 SNP,which is located in the open reading frame(ORF)of the IFITM3 gene,impacts the splicing procedure of protein production,which makes a truncated form of the IFITM3 protein and lowers its antiviral capacity.7–9 In addition,the rs34481144 SNP genotype affects the transcriptional regulation of the IFITM3 gene and IFITM3-neighboring genes and has a potent association with the clinical results of the H1N1 influenza 2009 pandemic in three human cohorts.10 Because several studies have reported that polymorphism of the IFITM3 gene is crucial in the host immune response,fine mapping of and extracting disease-associated SNPs from the human IFITM3 gene are important baseline studies necessary to understand how the IFITM3 protein functions in innate immunity.
