    Objectives The aim of this study was to determine the wound-healing potential of gold nanoparticles and silk fibroin-based nanofiber produced by green chemistry. Methods The electrospinning method was used to prepare the nanofiber. Twenty rats were exposed to a 7-day treatment period and another 20 rats were exposed to a 21-day treatment period. Rat groups were control, silver, silk fibroin, and silk + gold nanoparticle groups for each period. The effect of the gold nanoparticle/silk fibroin-based nanofiber was examined in skin samples by using biochemical and histological analysis. In biochemical analysis, skin oxidant and antioxidant parameters were determined. Key findings Parameters indicating skin damage returned to their previous levels 7 and 21 days after the wound formation using gold nanoparticle/silk fibroin-based nanofiber. Gold nanoparticle/silk fibroin-based nanofiber initiated hair follicle formation at the wound site and accelerated the re-epithelialization process. Conclusions It was found that the nanofiber prepared by adding gold nanoparticles to silk fibroin had better wound-healing properties than silk fibroin nanofibers without gold nanoparticles. © 2025 Elsevier B.V., All rights reserved.

    Neuroprotective Effect Of<i> Myrtus</I><i> Communis</I> Against Ionizing Radiation-Induced Brain Injury: Insights From Histopathological and Biochemical Analysis in Rats

    Aim: To investigate the potential radioprotective effects of Myrtus communis on brain tissue. Methods: Thirty female rats were divided into four groups. The control group (C) was applied with oral saline solution (SF) for four days. Myrtus communis (MC) groups started to receive MC (100 mg/kg, oral) either four days before (R + preMC) or immediately after (R + MC) irradiation for four days. Irradiation was applied 10 Gy in a single fraction. All rats were sacrificed on the fourth day of irradiation. Malondialdehyde (MDA), nitric oxide (NO), and glutathione (GSH) levels, myeloperoxidase (MPO), superoxide dismutase (SOD), and tissue factor activities (TFa) were determined for biochemical analysis. Hematoxylin&Eosin &Eosin staining was done for histopathological analyses, and electrophoretic analyses were performed. Results: NO, MDA, and MPO levels were higher in all irradiated groups compared with the C group. MC administration decreased NO, MDA, and MPO levels in R + preMC and R + MC groups. MC administration increased GSH levels. TFa activity decreased in R groups but did not change with MC administration compared to the C group. Radiation-induced brain tissue injury decreased, and morphologically normal neurons were observed in both MC-added groups. Conclusion: Myrtus communis has a potential neuroprotective effect on brain tissue, attributed to its antioxidative, anti-inflammatory, and anti-lipid peroxidative properties.
