Nature medicine (NM) offers promising treatments through its bioactive compounds, which target the multifaceted nature of stroke-induced damage.

This review article presents an advanced perspective on integrating nanotechnology with NM to create potent nanodelivery systems for ischemic stroke treatment. We highlight the pathological underpinnings of ischemic stroke, including oxidative stress, inflammation, and apoptosis, and discuss how NM compounds offer targeted mitigation strategies. By incorporating nanodelivery platforms, such as liposomes and nanoparticles, these NM -based treatments can achieve enhanced targeting, solubility, and controlled release, significantly improving therapeutic outcomes while reducing side effects. Despite promising developments, the translation of nano-enhanced NM into clinical practice faces obstacles, including manufacturing scalability, regulatory approval, and safety evaluations. This review emphasizes the potential of combining nanotechnology with NM to advance ischemic stroke therapy, calling for integrated research efforts to overcome existing barriers and fully realize the clinical benefits of this innovative approach.</p></div>","PeriodicalId":100180,"journal":{"name":"Biomedical Technology","volume":"7 ","pages":"Pages 32-45"},"PeriodicalIF":0.0,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949723X24000151/pdfft?md5=7ca6bcfb5188479a44a70cc5ccf9f911&pid=1-s2.0-S2949723X24000151-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141623405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To mimic and investigate this new clinical type of botulism, we established a novel animal model and evaluated the therapeutic potential of a new drug. Firstly, we injected BoNT/A into the gastrocnemius of rats to induce partial paralysis of the remaining limbs. Then, the intoxicated rats were treated with 3,4-diaminopyridine (3,4-DAP) at different stages of the disease and the forelimbs grasping strength (FGS) was evaluated. We showed that, at the sublethal dose, the FGS began to decrease at 6.00 ​± ​1.86 ​h after injection in rats, from 2.28 ​± ​0.19 ​N to 1.51 ​± ​0.18 ​N, while the FGS declined appeared earlier (4.29 ​± ​0.42 ​h) at the lethal dose, from 2.30 ​± ​0.20 ​N to 1.20 ​± ​0.16 ​N. Treatment with 3,4-DAP respectively at the time of the symptoms onset or 7 days after injection both can temporarily reverse the symptoms of muscle paralysis, indicating that 3,4-DAP may be an effective approach to relieve botulism. Overall, this study provides an available rat model and a promising therapeutic strategy for cosmetic injection-induced botulism.</p></div>","PeriodicalId":100180,"journal":{"name":"Biomedical Technology","volume":"7 ","pages":"Pages 25-31"},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949723X2400014X/pdfft?md5=33b378da876cfcc1ef62239719647f35&pid=1-s2.0-S2949723X2400014X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141540325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The myopia model in guinea pigs was successfully established by covering one eye of the guinea pigs with a latex bead sac for 4 weeks. This study used 4D data-independent acquisition proteomics technology to analyze vitreous body samples from both the FDM group and the control group. The goal of the proteomics analysis was to identify differences in protein expression within the vitreous body of FDM guinea pigs. Myopia was successfully induced in the FDM group after 4 weeks of modeling. A total of 6298 proteins were identified, among which 348 were differentially expressed proteins (DEPs), with 81 upregulated and 267 downregulated. These DEPs were subjected to in-depth bioinformatics analyses, including Gene Ontology, the Eukaryotic Orthologous Groups, and the Kyoto Encyclopedia of Genes and Genomes. These analyses revealed significant involvement in cellular processes, metabolic pathways, biological regulation, cytoskeletal organization, and cell movement. Our results indicate that calcium signaling plays a critical role in mediating eye changes associated with form deprivation, which may bear similarities to mechanisms observed in neurodegenerative diseases. A total of 348 DEPs related to the development and progression of myopia were identified. These changes involve key biological processes, including protein degradation, cell adhesion, and transport, especially alterations in calcium signaling pathways. Stromal interaction molecule 1 (STIM1) is an important biological marker of FDM, which was confirmed by Western blot, immunohistochemistry and ELISA. Our study found clear differences in the expression of proteins in the vitreous during the development of myopic guinea pigs, especially those related to calcium signaling pathway. Our study offers new insights into the pathogenesis of myopia, particularly changes related to protein metabolism pathways.</p></div>","PeriodicalId":100180,"journal":{"name":"Biomedical Technology","volume":"7 ","pages":"Pages 15-24"},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949723X24000126/pdfft?md5=c7b83f5cf95221d34931ea50c1ab4a18&pid=1-s2.0-S2949723X24000126-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141302971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
