Background: Cerebral ischemia is a common cause of disability and death. Ischemic brain injury results from complex pathological processes, including oxidative stress, inflammation, and apoptosis. Thioredoxin( Trx) is an important multifunctional protein, which regulates cellular redox status. Increasing studies have demonstrated that Trx provides a neuroprotective role against cerebral ischemia-induced injury.
Methods: A systematic search of PMC and the PubMed Database was conducted to summarize the protective effects of Trx against cerebral ischemia.
Results: This article reviews the understanding of potential effects and mechanisms of Trx against cerebral ischemia, including the anti-oxidant, anti-apoptotic and anti-inflammatory effects, as well as the activation of prosurvival pathway. We also summarize that some natural compounds induce the expression of Trx, which is involved in their anti-ischemic effects.
Conclusion: In conclusion, Trx has a potential neuroprotection in cerebral ischemia and may be very promising for clinical therapy of ischemic stroke in the future.

Esketamine at a Clinical Dose Attenuates Cerebral Ischemia/Reperfusion Injury by Inhibiting AKT Signaling Pathway to Facilitate Microglia M2 Polarization and Autophagy.

Purpose: This study aimed to assess the protective effect of a clinical dose esketamine on cerebral ischemia/reperfusion (I/R) injury and to reveal the potential mechanisms associated with microglial polarization and autophagy.
Methods: Experimental cerebral ischemia was induced by middle cerebral artery occlusion (MCAO) in adult rats and simulated by oxygen-glucose deprivation (OGD) in BV-2 microglial cells. Neurological and sensorimotor function, cerebral infarct volume, histopathological changes, mitochondrial morphological changes, and apoptosis of ischemic brain tissues were assessed in the presence or absence of esketamine and the autophagy inducer rapamycin.

is a gram-positive bacterium commonly found in dairy products and used as a probiotic due to its resistance to acid and bile. While generally considered safe, rare cases of bacteremia and endocarditis have been reported, primarily in individuals with significant risk factors. This report discusses an elderly male with a history of cardiovascular diseases, diabetes, and asthma, who developed bacteremia and endocarditis after consuming large quantities of Greek yogurt.

The chronic occlusion of intracranial arteries generally has no or mild clinical symptoms, and the clinical symptoms of acute cerebral artery occlusion are mostly manifested as severe cerebral infarction symptoms, which often make early diagnosis difficult, thus losing the best treatment opportunity. Once cerebral infarction occurs, the consequences are difficult to recover. This is also an important reason for the high misdiagnosis rate and mortality of this disease.

Purpose: Few data are available on the causality of cerebral artery fenestration (CAF) triggering cerebral infarction (CI) and this study aims to identify representative morphological features that can indicate risks.
Methods: A cohort comprising 89 patients diagnosed with CAF were enrolled from a total of 9,986 cranial MR angiographies. These patients were categorized into Infarction Group ( = 55) and Control Group ( = 34) according to infarction events.

Pulmonary arteriovenous malformations (PAVM) are characterized by abnormal pulmonary vessels forming arteriovenous shunts that compromise oxygenation of the blood, causing hypoxemia, and predispose to infections and cerebral ischemia. The patient in this case was a 38-year-old male who presented with tachypnea and dyspnea, cyanosis of extremities, and significant digital clubbing. The patient had structural epilepsy secondary to neurosurgery for a cerebral abscess during childhood.
