Epilepsy is a group of neurological disorders characterized by abnormal electrical activity in the central nervous system (CNS) and recurrent seizures representing the principal clinical manifestation. Sudden unexpected death in epilepsy (SUDEP) is the predominant cause of death in young epileptic patients. SUDEP patients displayed an increased cardiovascular (CV) risk, probably due to an impaired autonomic control of CV functions, but the underlying mechanisms need to be explored yet. Therefore, we aimed to examine the cardiac morphological alterations in a pentylenetetrazol (PTZ)-kindled rat model, a well-established tool for studying chronic epilepsy. To complete this, the distance between the atria, between the atrium and ventricle were measured, the heart was weighed, and the pathological morphology of dissected hearts was analyzed by histological assessment with hematoxylin and eosin staining. A significantly decreased distance between atria and a significant increase in heart weight were observed in PTZ-kindled rats which interestingly also displayed increased hemorrhagic content when compared with controls. Our findings provided evidence that changes in cardiac morphology may be related to autonomic CV dysfunctions occurring during SUDEP while also opening up more avenues to better develop novel drugs for the treatment of this disorder.

The electromagnetic field (EMF) is a physical concept consisting of electric and magnetic fields produced by the motion of charged particles and plays a ubiquitous role in modern society. EMFs are present in various forms, ranging from extremely low frequency (ELF) fields produced by power lines to radiofrequency (RF) fields emitted by wireless communication devices. While EMFs are essential for technologies like electricity generation, telecommunications, and medical imaging, concerns have been raised regarding their potential impact on human health. The literature has explored the relationships between EMF exposure and health outcomes, including cancer, reproductive health, and neurological disorders. Despite ongoing debate and inconclusive evidence, efforts are underway to mitigate exposure and establish regulatory guidelines. The effects of EMF on human health is a complex and multifaceted issue and research points to potential effects on various aspects of health, including neurological, reproductive and developmental effects. Although significant associations have not been found in some studies, growing evidence suggests that continuity in research is important in assessing and mitigating potential health risks associated with EMA exposure.

Introduction: Mistletoe has been used alone or as a complementary therapy in the treatment of different diseases for years. In this study, the antitumoral effect of mistletoe fruit extract on Ehrlich ascites tumor (EAT) cells was evaluated. Materials and Methods: EAT cells from preformed stock mice were transferred to culture dishes containing 5-fluorouracil (5-FU) and mistletoe extracts at different doses (100, 200, 400, and 800 μg/ml). These cells were incubated at 37 °C in an environment with 95% humidity and 5% CO2. At the end of the incubations, the apoptosis status of the cells, cell cycle, mitochondrial membrane potential, and proliferation status with the argyrophilic (Ag) nucleolar organizer region staining (NORs) method were evaluated. Results: As a result, it was observed that the mistletoe fruit extract and 5-FU induce apoptosis of EAT cells. It was concluded that the 5-FU substance arrests the cell cycle at the G0/G1 stage, while the mistletoe arrests the cell cycle at the S and G2/M stages. The depolarization rate of the mistletoe treated cells was higher. As a result of the evaluation made with the AgNORs method, it was seen that mistletoe and 5-FU could be effective in reducing the proliferation of EAT cells. Conclusions: It was seen that mistletoe fruit extract could be effective in stimulating the apoptosis and depolarization of cancer cells. The results of other studies in the literature and our study support each other. It was concluded that the mistletoe plant may be useful in cancer treatment.
Aim: Accessory and sesamoid bones are hidden anatomical structures that fulfil a wide variety of functions in the human body. Therefore, studying the nature, formation and dimensions of these structures is of great importance for the medical literature. In our study, we aimed to measure the presence and area (size) of these ossicles. Material and Method: Our study was performed retrospectively on the images of individuals who applied to Ordu University and whose radiological images were obtained. The presence of accessory and sesamoid ossicles (present/absent) and their sizes (measured using the PACS system) were evaluated on radiographs and Computed Tomography (CT) images. The results of the ossicles were divided into gender, age, and bilateral groups. Statistical analyzes were performed with the SPSS program. Results: The most common and largest accessory ossicles in the foot were os peroneum (18.2%), os naviculare accessoria (17.4%), os trigonum (12.1%) and os intermetatarsarum (7.8%). Sesamoid ossicles at the level of the first metatarsophalangeal (mtp) joint of the foot and the first metacarpopgalangeal (mcp) joint of the hand were found to be 100% common. The second most common sesamoid bone in the hand and foot was at the fifth mtp (22.22%) and mcp (68.53%) joints. In the hand, the most common accessory ossicles were os triangulare (6.08%), os radiale externum (2.60%) and os centrale (1.73%). Accessory ossicles (fabella: 19%, cyamella: 17.5%) were found in 25.5% of the knee. Conclusion: Accessory and sesamoid ossicles are most commonly found in the hand, foot, and knee. The presence and size of these ossicles can be both beneficial and harmful. Sesamoids provide mechanical benefit, whereas accessory ossicles can be mistaken for fractures and may lead to unnecessary medical conditions. Knowing the dimensions of these ossicles allows them to be clinically differentiated from avulsion fractures.
