    OBJECTIVE: This study aimed to investigate the in vivo radioprotective effects of Myrtus communis (MC) on the gastrointestinal system. METHODS: A total of 30 female rats were divided into four groups: i) Control; ii) irradiation (IR) only; iii) MC-pretreated; and iv) MC-treated. The rats received oral MC extract (100 mg/kg/day) for 4 days before exposure to 10 Gy IR or continued until sacrifice. On the fourth day of IR exposure, the rats were sacrificed, and histopathological and biochemical analyses were performed on the ileum, pancreas, and liver tissues. RESULTS: Malondialdehyde and myeloperoxidase levels decreased in both MC-treated groups, while glutathione levels and Na+-K+-ATPase activity increased (p<0.01), with significant histopathological improvements compared to the IR-only group. CONCLUSION: The results of this study demonstrate that MC significantly decreases ionizing radiation-induced oxidative and inflammatory damage in the gastrointestinal systems of rats. Therefore, it may be regarded as a new candidate with radioprotective potential for future clinical application.

    Gold Nanoparticle/Silk Fibroin-Based Nanofiber Enhances Skin Regeneration
    (Oxford University Press, 2025) Özcan, Ozan; Tufan, Elif; Muhan, Aleyna Tanrıverdi; Çalişkan-Ak, Esin; Şener, Göksel; Tunalı-Akbay, Tuǧba; Ak, Esin
    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.
