Multi-functional bandage - bioactive glass/metal oxides/alginate composites based regenerative membrane facilitating re-epithelialization in diabetic wounds with sustained drug delivery and anti-bactericidal efficacy

Chronic wounds, especially diabetic, foot and pressure ulcers are a major health problem affecting >10 % of the world's populace. Calcium phosphate materials, particularly, bioactive glasses (BG), used as a potential material for hard and soft tissue repair. This study combines nanostructured 45S5 BG with titania (TiO2) and alumina (Al2O3) into a composite via simple sol-gel method. Prepared composites with alginate (Alg) formed a bioactive nanocomposite hydrogel membrane via freezing method. X-ray diffraction revealed formation of two phases such as Na1.8Ca1.1Si6O14 and β-Na2Ca4(PO4)2SiO4 in the silica network. Fourier transformed InfraRed spectroscopy confirmed the network formation and cross-linking between composite and alginate. <2 % hemolysis, optimal in vitro degradation and porosity was systematically evaluated up to 7 days, resulting in increasing membrane bioactivity. Significant cytocompatibility, cell migration and proliferation and a 3-4-fold increase in Collagen (Col) and Vascular Endothelial Growth Factor (VEGF) expression were obtained. Sustained delivery of 80 % Dox in 24 h and effective growth reduction of S. aureus and destruction of biofilm development against E. coli and S. aureus within 24 h. Anatomical fin regeneration, rapid re-epithelialization and wound closure were achieved within 14 days in both zebrafish and in streptozotocin (STZ) induced rat in vivo animal models with optimal blood glucose levels. Hence, the fabricated bioactive membrane can act as effective wound dressing material, for diabetic chronic infectious wounds.

Prostate cancer is the second most common cause of cancer deaths for men. Lippia. Nodiflora (L. nodiflora) has been used as a natural remedy for various diseases, because of its antioxidant, anti-inflammatory, anti-bacterial, and anti-tumor effect. This study was to investigate the cytotoxic effect of L. nodiflora ethanolic leaf extract in prostate cancer cell lines (PC-3). The growth inhibitory effect of L. nodiflora ethanolic leaf extract was assessed by MTT assay. The cell morphological changes in L. nodiflora leaf extract-treated cells were observed using an inverted phase-contrast microscope. Apoptosis induction by L. nodiflora was determined by AO/EtBr (acridine orange and ethidium bromide) dual staining. MTT test results showed dose-dependent cell growth inhibition in PC-3 cells treated with L. nodiflora leaf extract (10-120 µg/mL). The IC-50 dose was observed at 40µg/ml. Morphological changes such as reduction in the number of cells, cell shrinkage, and cytoplasmic membrane blebbing were observed in the treated cells. Induction of apoptosis by L. nodiflora (40µg/ml) treated cells showed an increased number of early apoptotic and late apoptotic cells. The above data indicate that L. nodiflora inhibits cell proliferation and induces apoptosis in prostate cancer cells. Therefore, it can be concluded that L. nodiflora exhibits anti-cancer activity, and thus it raises new hope for its use in anti-cancer therapy.

The skin cancer cells were treated with different concentration Lippia nodiflora leaf extract for 24h. We calculated the optimum (IC-50; 20µg/ml) using the MTT assay, which was then used for further analysis. A phase-contrast microscope is used to analyse changes in cell morphology. AO/EtBr dual staining under a fluorescence microscope was used to determine the effect of Lippia nodiflora on B16-F10 cell death. Results: In our research, the cell viability of the B16-F10 skin cancer cell line was dramatically decreased after treatment with different concentrations (5-60 µg/ml) of Lippia nodiflora for 24 hours. 50% inhibition was detected at a concentration of 20 µg/ml, which was determined to be an inhibitory concentration (IC-50) value and used in subsequent studies. The viable cell will possess a uniform bright green nucleus. Early apoptotic cells will have bright orange areas of condensed or fragmented chromatin in the nucleus. Late apoptotic cells will have uniform bright red nucleus. Conclusion: The findings of this analysis revealed that Lippia nodiflora leaf extract inhibits the cell viability and indces apoptosis of skin cancer cells. Thus, Lippia nodiflora exhibits anti-cancer effects against skin cancer cells, therefore it raises new hope for anti-cancer therapy.
