Objective: The aim of this study was to investigate the role of ferroptosis in the occurrence of postoperative cognitive dysfunction (POCD) using a mouse model and to elucidate whether electroacupuncture (EA) can improve POCD by suppressing ferroptosis via the transferrin receptor 1 (TFR1)-divalent metal transporter 1 (DMT1)-ferroportin (FPN) pathway.
Methods: The experiment involved three groups: the control group, the POCD group and the POCD + EA group. The POCD animal model was established using sevoflurane anesthesia and tibial fracture.

Background: Magnolia kobus DC (MO), as a plant medicine, has been reported to have various physiological activities, including neuroprotective, anti-inflammatory, and anti-diabetic effects. However, vascular protective effects of MO remain incompletely understood. In this study, we evaluated the vascular protective effect of MO against ferroptosis in a carotid artery ligation (CAL)-induced neointimal hyperplasia mouse model and in aortic thoracic smooth muscle A7r5 cells.

This study aimed to evaluate the antihyperglycemic and antioxidant activities of the lectin isolated from (BTL). Diabetes was induced in Wistar rats through low-dose streptozotocin injections. Following the confirmation of hyperglycaemia, the animals were treated with 150 mM NaCl, glibenclamide, or BTL at 600 or 900 mg/kg.

Objective: Post-resuscitation brain injury is a common sequela after cardiac arrest (CA). Increasing sirtuin1 (SIRT1) has been involved in neuroprotection in oxygen-glucose deprivation (OGD) neurons, and we investigated its mechanism in post-cardiopulmonary resuscitation (CPR) rat brain injury by mediating p65 deacetylation modification to mediate hippocampal neuronal ferroptosis.
Methods: Sprague-Dawley rat CA/CPR model was established and treated with Ad-SIRT1 and Ad-GFP adenovirus vectors, or Erastin.

Depression is a common and complex neuropsychiatric disorder affecting people of all ages worldwide, associated with high rates of relapse and disability. Neohesperidin (NEO) is a dietary flavonoid with applications in therapeutics; however, its effects on depressive-like behavior remain unknown. Here, we evaluated the effects of NEO on depressive-like behavior induced by chronic and unpredictable mild stress (CUMS).
