Silver-releasing bioactive glass nanoparticles for infected tissue regeneration.

Bacterial infections represent a formidable challenge, often leaving behind significant bone defects post-debridement and necessitating prolonged antibiotic treatments. The rise of antibiotic-resistant bacterial strains further complicates infection management. Bioactive glass nanoparticles have been presented as a promising substitute for bone defects and as carriers for therapeutic agents against microorganisms.

Application of single cell force spectroscopy (SCFS) to the assessment of cell adhesion to peptide-decorated surfaces.

The adhesion forces of cells to peptide-coated functionalized materials were assessed through the Single Cell Force Spectroscopy (SCFS) technique in order to develop a methodology that allows the fast selection of peptide motifs that favor the interaction between cells and the biomaterial. Borosilicate glasses were functionalized using the activated vapor silanization process (AVS) and subsequently decorated with an RGD- containing peptide using the EDC/NHS crosslinking chemistry. It is shown that the RGD-coated glass induces larger attachment forces on mesenchymal stem cell cultures (MSCs), compared to the bare glass substrates.

Accuracy of CAPRA-S Score for Predicting Long-Term Biochemical Progression After Radical Prostatectomy.

Background: The Cancer of the Prostate Risk Assessment Postsurgical (CAPRA-S) score is a tool to stratify patients into groups according to their risk for biochemical recurrence after radical prostatectomy. The aim of this study was to assess the accuracy of the CAPRA-S score for predicting biochemical progression at 5 and 10 years in our cohort of patients after radical prostatectomy.

Patients And Methods: Between June 2004 and December 2015, radical prostatectomy was performed as the main treatment option for patients with localized prostate cancer.
