Mortality from cancer in 90% of cases is caused by the development of metastases, which are the clinical result of the invasiveness of the pathology. Among the known metastasis suppressor molecules are the products of the <i>KISS1</i> gene—the metastin protein and its derivatives: kisspeptin-14 (KP14), kisspeptin-13 (KP13) and kisspeptin-10 (KP10). The KISS1/KISS1R system regulates the development and progression of several types of cancer. These molecules are important in the development of new treatment methods and/or as markers in the treatment of cancer, so the biologically active kisspeptin analogues design and synthesis is a promising direction for the development of drugs that prevent the metastases formation. In this study, promising sequences of kisspeptin and its modified analogues—KP-10, KP-10-dAla, KP-6-dAla—were designed.

Approximately 20 million hernioplasty operations are performed annually, at least 85% of which involve the use of surgical meshes. This interest of specialists in hernias is due to serious reasons, first of all, strangulation, which is a life-threatening complication and often leads to death. According to various authors, from 3 to 8% of the population suffer from hernias, and at least 20 million people in the world undergo hernia repair every day, and they are recently increasingly using endoprosthetic meshes from various manufacturers for hernial orifice repair. Often, hernia mesh causes postoperative complications, such as adhesions, wrinkling of the mesh, granulomas, fistulas, seromas, including infection of the implant, leading to the development of abscesses and possibly sepsis. To reduce these complications, various modifications of endoprosthetic meshes and materials are being developed. However, there is not a single mesh at present that would completely satisfy hernia surgeons. Based on the above, the authors set a goal to improve the functional and antibacterial properties of polypropylene endoprosthetic mesh using atomic layer deposition (ALD) nanotechnology. The ALD method consists in that a nanofilm is created on the surface of the endoprosthetic mesh through cyclic reactions using trimethylaluminum, titanium tetrachloride, and vanadium trichloroxide. The authors have obtained the first samples of meshes that were implanted into the bodies of experimental animals. The experimental samples demonstrated good biocompatibility and integration into the surrounding tissue, preventing any inflammatory response. The developed method for improving the functional and antibacterial properties of endoprosthetic meshes is simple in industrial implementation compared to PACVD or CVD and allows covering large areas, therefore, reducing material production costs and increasing the economic efficiency of domestically produced mesh implants and making them competitive in the world market.</p>","PeriodicalId":485,"journal":{"name":"Biochemistry (Moscow), Supplement Series B: Biomedical Chemistry","volume":"18 4","pages":"355 - 360"},"PeriodicalIF":0.6,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143108011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
