Article The Therapeutic Role of Ginseng in Promoting Hippocampal Neurogenesis and Ameliorating Cognitive Function Following Whole Brain Radiotherapy in Rats(Springer/Plenum Publishers, 2025) Sahin, Sevim; Bayindir, Nihan; Ertas, Busra; Ceylan, Cemile; Elibol, Birsen; Ozkan, Alper; Sener, GokselWhole-brain radiotherapy (WBRT) is a prevalent technique for managing multiple intracranial metastases, however, the cognitive damage in long-term survivors due to WBTR is a critical concern that impacts patients' quality of life. Panax ginseng, a bioactive compound recognized for its neuroprotective benefits, also enhances cognitive functions, including memory and learning. This study aims to examine the potential protective effects of Panax ginseng supplementation on cognitive dysfunction and the levels of neurogenesis-related proteins in the hippocampus of rats that underwent WBRT, which was delivered as 3 fractions of 6 Gy (total dose 18 Gy) using a linear accelerator. Thirty-six male Sprague-Dawley rats were divided into three groups: radiation, ginseng treatment, and control. After 60 days of Panax ginseng administration (100 mg/kg), behavior tests (Morris water maze and novel object recognition) were performed, followed by western blot analysis of the hippocampus. Results indicated that Panax ginseng supplementation ameliorated radiation-induced cognitive impairments. Additionally, western blot analyses revealed that Panax ginseng promoted neuronal recovery and neuroplasticity processes in the hippocampus, simultaneously exhibiting a neuroprotective mechanism by reducing apoptosis and neurotoxicity markers. Panax ginseng ameliorates cognitive dysfunction after WBRT by enhancing neurogenesis and diminishing cell death in the hippocampus.Article Effectiveness of Individual Psychoeducational Interventions for Caregivers of Stroke Patients: A Systematic Review and Meta-Analysis(Springer/Plenum Publishers, 2025) Kelani, Hesham; Ali, Hossam Tharwat; Naeem, Ahmed; Salamah, Hazem Mohamed; Ismail, Ali; Younes, Youmna Atef; Khandelwal, PriyankStroke is a major cause of disability, and patients who suffer strokes have limited mobility and functional tasks, necessitating daily reliance on caregivers. However, caregivers of stroke patients often experience depression and anxiety, negatively impacting their mental health and reducing their quality of life. Psychoeducational interventions may be a solution to support the well-being of stroke caregivers. This study is performed to assess the overall effectiveness of individual psychoeducational interventions for caregivers of stroke patients. A thorough search of Scopus, PubMed, Web of Science, and Cochrane databases was performed for published studies in English up to June 2023. Clinical trials assessing the efficacy of psychoeducational interventions on quality of life, depression, or care burden among stroke caregivers compared to usual care were included. A total of 18 clinical trials, 16 randomized clinical trials (RCTs), and two non-RCTs, with a total of 2007 patients, were included. The study's pooled results revealed a significant increase in the quality of life in the group receiving psychoeducational interventions compared to the comparison group (SMD = 0.34, 95% CI 0.13-0.55, p value = 0.002), while no significant difference was found in terms of depression (SMD = - 0.05, 95% CI - 0.23 to 0.14, p value = 0.62) or caregiver burden (SMD = - 0.61, 95% CI - 1.65 to 0.44, p value = 0.25). Psychoeducation programs should be considered as a supportive intervention to improve quality of life in caregivers; however, their impact on depression and caregiver burden remains inconclusive. However, further studies with a larger sample size are needed to confirm the results.Article Protective Effect of Artichoke (Cynara scolymus L.) Leaf and Receptaculum Extracts Against Hepatic Encephalopathy in Bile Duct Ligated Rats(Springer/Plenum Publishers, 2025) Kam, Ozkan; Bebitoglu, Berna Terzioglu; Sener, Goksel; Oguz, Elif; Erdogan, Nurettin Fatih; Kilickap, Andac; Hatiboglu, NebileHepatic encephalopathy (HE), complication of liver dysfunction, leads to neurocognitive impairments. Artichoke (Cynara scolymus L.) has been traditionally used for its antioxidant, anti-inflammatory and hepatoprotective properties. This study evaluates artichoke leaf and receptaculum extracts in cholestasis and HE in a rat model. Wistar rats were divided into 6 groups: sham-control, bile duct ligation (BDL), and BDL with low/high-dose leaf or receptaculum extracts. After BDL, physiological saline and extracts (250/500 mg/kg) were administered orally for 28 days. Cognitive activity was evaluated using Morris water maze and novel object recognition tests on day 28. Artichoke extract regulated liver enzymes and bilirubin at high-doses and significantly increased antioxidant enzyme activities reduced by BDL. Elevated 8-Hydroxyguanosine (8-OHdG) levels decreased in liver and brain tissues. Similarly, artichoke extracts reduced cytokine and hydroxyproline (HP) levels elevated by cholestasis. Following BDL, Na+/K+-ATPase levels in brain and liver tissues decreased, while artichoke extract reversed this. Artichoke, particularly high-dose receptaculum, improved impaired performance and increased time in the target quadrant after BDL. Both artichoke leaf and receptaculum extracts improved recognition. Artichoke treatments, especially high-dose receptaculum, reduced hepatic and neuronal damage and improved histological appearance. These findings highlight the therapeutic potential of artichoke extracts for liver fibrosis and related neurocognitive disorders.
