Example of digital exhibition in anthropology and medical education

Technology brings new opportunities in terms of education and research, and global pandemics such as the recent COVID-19 pandemic require online education-style approaches. Visualisation is of great importance in digitised education. In this study, materials that are of interest to the disciplines of anthropology, dentistry and medicine were selected from the skeletal materials and presented in a virtual exhibition. The mandible samples were digitised by photogrammetric method, and the exhibition was made navigable by using the Unity game engine program. In the exhibition, information on dental and bone physiology and palaeopathology, as well as the mandibles of the skeletons obtained from the excavation area, and information on individuals are presented on informative boards. The exhibition can be visited online with the link provided. In this study, the opinions of 30 students, who visited the exhibition from Faculty of Medicine 3rd-5th classes, were asked to complete an online questionnaire. Results of this questionnaire show that students would like to see more of such digital education methods. Digitising educational presentations enables these exhibitions to transcend physical boundaries and reach a global audience. In addition, the images can be easily examined by anyone who visits and can be evaluated for educational purposes.

Melatonin is effective in attenuating cisplatin-induced neurotoxicity

Cisplatin (Cis) is a chemotherapeutic agent that has many side effects. Neurotoxicity is one of the most important of these side effects. Oxidative stress and neuroinflammation are the best-known mechanisms in the pathogenesis of neurotoxicity development. In this study, we aimed to determine whether melatonin (Mel), with antioxidant and anti-inflammatory effects, is effective in preventing Cis-induced neurotoxicity. Forty-eight male Sprague-Dawley rats were divided into six groups (n = 8) as follows: control (0.9% NaCl), vehicle (5% ethanol), Cis (6 mg/kg), Cis (6 mg/kg) + vehicle (5% ethanol), Mel (20 mg/kg), and Cis (6 mg/kg) + Mel (20 mg/kg) groups. Cis was administered as a single dose on the 3rd day of the experiment while Mel was given for 5 days. All administrations were performed via intraperitoneal injection. After injections, T-maze, rotarod, and hot plate tests were performed to evaluate cognitive, motor, and sensory functions, respectively. Following sacrification oxidative stress markers, cholinergic function, and proinflammatory cytokines were studied from brain homogenates. Cis impaired cognitive function and motor performance in the Cis and Cis+Vehicle groups. The drug also increased oxidative stress in the brain. Mel significantly improved brain oxidant/antioxidant status and also decreased the overproduction of proinflammatory cytokines (superoxide dismutase activities in Cis+Vehicle and Cis+Mel groups: 104.55 ± 9.50 µU/mg protein vs. 150.13 ± 4.70 µU/mg protein, respectively, p < 0.05; tumor necrosis factor-α levels in Cis and Cis+Mel groups: 40 pg/ml vs. 20 pg/ml, respectively, p < 0.05). It seems that Mel can improve Cis neurotoxicity. For a more firm conclusion, further studies using Mel at different doses with larger groups should be performed.
