Comparison of surgical approaches to the hippocampal formation with artificial intelligence.

The relatively complex functional anatomy of the mediobasal temporal region makes surgical approaches to this area challenging. Several studies describe various surgical approaches, along with their combinations and modifications, to reach lesions of this region. Some of these surgical approaches have been compared using artificial intelligence-based approaches that can be predicted, classified, and analyzed for complex data.

Oxidative Stress Level in Patients with Subarachnoid Hemorrhage.

Background: One of the antioxidant mechanisms is the dynamic balance between thiol and disulfide, which, in subarachnoid hemorrhage and other chronic diseases, is disrupted in favor of the latter. The two most commonly used oxidative stress (OS) biochemical markers are the oxidative stress index (OSI) value, which indicates the total oxidant status (TOS) and total antioxidant status (TAS) balance, and the thiol-disulfide (TDS) value, which indicates the total thiol (TT) and native thiol (NT) balance. High OS levels require further investigations.
