Some of the common symptoms are fever, chills, rapid heartbeat, difficulty breathing, confusion, and changes in mental status with occasionally pale, clammy, and mottled skin. Early diagnosis and identification are the keys to a successful treatment for sepsis patients. Researchers have developed nanoparticles to enrich bacterial populations followed by detection and applied them to conventional methods such as phenotypic and molecular diagnostics to enhance different detectors' responses toward pathogens. This short review systematically overviews steps that are followed in clinical labs for bacterial detection, identification, and their drawbacks. In this context, we discuss the role that nanoparticles can play in overcoming the limits of traditional microbiology methods in terms of turnaround times (TATs) and accuracy. We believe that this short review will provide up-to-date information about the applications of nanoparticles in the enrichment, separation, and identification of bacterial infection in the clinical field and, therefore, a way of rapid treatment.","PeriodicalId":74240,"journal":{"name":"Nanomedicine (London, England)","volume":" ","pages":"985-1000"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12051562/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143812963","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}

Lipid nanocapsules (LNC) carrying Förster resonance energy transfer (FRET) trackers have been previously developed, and a quantification method has been applied in blood samples.Materials & method: A quantification method in liver, spleen, and lungs was developed, and the biodistribution of intact FRET-LNC of 50 nm (FRET-LNC-50) in rats after intravenous injection was performed.Results: FRET-LNC-50 were extracted from organs using a newly developed extraction method, allowing their integrity preservation and quantification. This method allowed the assessment of the biodistribution study of intact LNC. A non-compartmental PK analysis was performed to calculate PK parameters. The most exposed organ was the liver, with a longer half-life than blood and other organs. The availability of specific biodistribution data allowed the development of the first physiologically based PK (PBPK) model, which represents an ideal platform to further aggregate biodistribution data from various nanoparticle types and to bring insight into PK mechanisms and structure-properties relationships of nanoparticles.Conclusion: This study presents the first biodistribution analysis of intact LNC using a validated quantification method, enabling the development of a PBPK model that improves the understanding of nanoparticle PK mechanisms.","PeriodicalId":74240,"journal":{"name":"Nanomedicine (London, England)","volume":"20 10","pages":"1101-1112"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12068743/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144001578","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}

However, critical obstacles remain, including overdiagnosis, high rates of negative biopsies, management of side effects, and the timely detection of relapse. Despite these improvements, surgery and radiotherapy are still associated with a significant risk of short- or long-term side effects. MXenes are a novel class of two-dimensional nanomaterials manufactured through electrochemical procedures that accept a wide-termination of hydrophilic molecules as surface modifications. The importance of MXene has increased owing to many aspects, such as its high-gain synthesis potential, chemical flexibility, and high biocompatibility. Hence, MXene is a convenient nanomaterial that can be modified and synthesized in different models, suggesting its ability to improve screening, diagnosis, and theranostic applications, such as thermal therapy. These features have been used to detect potential urothelial tumor markers as well as the direction and accumulation of cancer medications in the target tissue.","PeriodicalId":74240,"journal":{"name":"Nanomedicine (London, England)","volume":"20 9","pages":"1001-1014"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12051545/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144037957","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}

Surgery was performed 8 to 12 weeks after completion of CCRT.Results: Thirty-two patients were enrolled (one dropped out before CCRT), comprising 20 in phase Ib and 12 in phase II. The disease control rate was 100% (n = 31). One (3.2%) and 19 (61.3%) patients achieved clinical complete response and partial response, respectively. Twenty-five patients underwent surgery, of whom 24 (96%) had R0 resection and 5 (20%) had pathological complete response. Most of the adverse events were grade 1/2 events.Conclusion: Intratumor injection of PEP503 (NBTXR3) in patients with locally advanced or unresectable rectal adenocarcinoma is safe and effective.

This study evaluates the therapeutic potential of itacitinib (ITA) encapsulated in wheat germ agglutinin-functionalized nanoparticles (WGA/F127/PNPs) to target and inhibit the JAK-STAT pathway in slan+ monocytes.Methods: We prepared ITA-loaded WGA/F127/PNPs and analyzed their binding and internalization in various leukocyte subsets using flow cytometry, focusing on slan+ and slan- monocytes. Further, peripheral blood samples from healthy controls (n = 37) and SLE patients (n = 50) were used to assess slan+ monocyte phenotypes. Co-cultures of slan+ and slan- monocytes stimulated with LPS revealed that slan+ monocytes significantly increased HLA-DR expression.Results: Results showed that slan+ monocytes from SLE patients were reduced compared to healthy controls (p < 0.001) and that slan+ monocytes effectively internalized WGA/F127/PNPs, unlike slan- cells. ITA-loaded nanoparticles decreased HLA-DR, CD69, and CD86 expression, STAT1 phosphorylation, and cytokine production in IFN-γ-stimulated slan+ monocytes. Findings support WGA/F127/PNPs as a promising drug delivery system for targeting slan+ monocytes, providing new therapeutic potential for SLE.Conclusion: ITA-loaded WGA/F127/PNPs effectively target and suppress pro-inflammatory slan+ monocytes, presenting a promising, cell-specific therapeutic approach for managing systemic lupus erythematosus and related autoimmune disorders.","PeriodicalId":74240,"journal":{"name":"Nanomedicine (London, England)","volume":"20 10","pages":"1113-1126"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12068337/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144030714","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}
