Article Synergistic Effects of Amniotic Membrane and Human Milk Exosomes on Burn Wound Healing(Elsevier Sci Ltd, 2025) Isik, Ferda; Tufan, Elif; Sivas, Guzin Goksun; Ak, Esin; Muhan, Aleyna; Sener, Goksel; Tunali-Akbay, TugbaBackground: Thermal burns are one of the most common burns. Studies are ongoing to develop synthetic or biological wound dressings to ensure painless and scarless healing of burn wounds. Objectives: This study aimed to combine the human amniotic membrane with breast milk-based exosomes and investigate their effects on burn wound healing. Methods: 24 Wistar Albino rats weighing 200-250 g and of both genders were used. Rats were divided into control, burn, burn+human amniotic membrane (hAM) and burn+hAM+Exosomes (hAM+Exo) groups. Burn injury was induced by exposing the back of rats to 90 degrees C water for 10 s. Rats were treated with hAM and hAM+ Exo for seven days after injury. At the end of the 7th day, the skin samples were taken and analyzed biochemically and histologically. TNF-alpha, IL-1(i, type III collagen, malondialdehyde (MDA), glutathione (GSH), total protein, superoxide dismutase (SOD), and tissue factor (TF) activity were determined in skin samples. Results: In the burn group, skin TNF-alpha levels increased, IL-1(i and type III collagen levels decreased. Wound healing therapy reversed these results. In the hAM+Exo group, the TNF-alpha level was lower, and IL-1 beta and type III collagen levels were higher than in the hAM group. MDA and total protein levels increased, and GSH, tissue factor, and SOD activities decreased in the burn group. In hAM and hAM+Exo groups, MDA levels decreased, and GSH and SOD activity increased compared to the burn group. The GSH levels were significantly higher in the hAM+Exo group compared to the hAM group. Conclusion: In conclusion, combining exosomes and amniotic membrane induced changes consistent with better wound healing than amniotic membrane alone.Conference Object The Effect of Myrtus Communis Extract on High Fat Diet Induced Liver Damage in Rats(Wiley, 2025) Sucu, Gizem; Kabatas, Gul Sinemcan; Ertas, Busra; Sen, Ali; Sener, Goksel; Ercan, Feriha; Akakin, DilekArticle Citation - WoS: 18<i>petroselinum Crispum</I> Extract Ameliorates Scopolamine-Induced Cognitive Dysfunction: Role on Apoptosis, Inflammation and Oxidative Stress(Tsinghua Univ Press, 2022) Sener, Goksel; Karakadioglu, Gozde; Ozbeyli, Dilek; Ede, Seren; Yanardag, Refiye; Sacan, Ozlem; Aykac, AsliThis study was designed to investigate whether Petroselinum crispum (PC) extract has protective effects on the brain in the scopolamine-induced Alzheimer's disease (AD) rut model. The rats were divided into; control, scopolamine (1 mg/kg, i.p.), galantamine (1.5 mg/kg, i.p.) and PC extract (2 g/kg, p.o.)-treated scopolamine groups. On day 14, the novel object recognition test (NORT) and Morris water maze test (MWMT) were performed and then the rats were sacrificed. Scopolamine-induced cognitive impairments observed in the NORT and MWMT, significantly improved with PC extract and galantamine treatments. Scopolamine reduced M, receptor expression, Bcl-2/Bax ratio, and glutathione levels in the hippocampus and frontal cortex, while malondialdehyde levels, caspase-3/9 expressions, and acetylcholinesterase (AChE) activity were found to be increased. On the other band, PC and galantamine treatments reversed these changes. In conclusion, PC extract has shown an ameliorative effect on the spatial and recognition memory, M-1 receptor expression, apoptosis, oxidative stress, and increased AChE activity. Thus, it was concluded that PC could prevent AD-like conditions and can be used as a functional food. However, since animal models do not completely mimic those of humans, based on the data obtained in this study, the importance of PC on human AD should be demonstrated in future studies.

Rats with colitis induced via intra-rectal acetic acid administration (5%, v/v) received RTME or sulfasalazine for three consecutive days. On day four, all rats were decapitated, and the colonic tissue samples were collected for macroscopic score, colon weight, reduced glutathione (GSH), myeloperoxidase (MPO), and malondialdehyde (MDA) analyses. The active compounds and chemical composition of RTME were determined by bio-guided isolation and LC-MS/MS, respectively. Compared to the colitis group, the rats treated with RTME displayed significantly lowered macroscopic scores and colon wet weights (p < 0.001). These effects were confirmed biochemically by a decrease in colonic MPO activity (p < 0.001), MDA levels (p < 0.001), and an increase in GSH levels (p < 0.001). Kaempferol-3-O-beta-D-glucuronide (RT1) and quercetin-3-O-beta-D-glucuronide (RT2) were found to be the major compounds of RTME, as evidenced by in vitro anti-inflammatory and antioxidant activity-guided isolation. Their anti-inflammatory/antioxidant activities were also predicted by docking simulations. Additionally, quinic acid, 5-caffeoylquinic acid, quercetin pentoside, quercetin glucoside, quercetin3-O-beta-D-glucuronide, kaempferol-3-O-beta-D-glucuronide, and kaempferol rutinoside were identified in RTME via using LC-MS/MS. RT2, along with other compounds, may be responsible for the observed protective action of RTME against colitis. This study represents the first report on the beneficial effects of RTME in an experimental model of colitis and highlights the potential future use of RTME as a natural alternative to alleviate colitis.
