AI Article Synopsis
- Cerebral stroke is a leading cause of death with no effective treatments yet, prompting research into bone marrow mesenchymal stem cells (BMSCs) for recovery post-ischemic stroke.
- A rat model of ischemic cerebral infarction was created, and MRI techniques showed significant improvements in brain structure and function after BMSCs were injected.
- The study concluded that BMSCs help repair brain damage from strokes and highlighted the usefulness of advanced imaging technologies in monitoring recovery.
Article Abstract
Background: Cerebral stroke is the second leading cause of death with high mortality and morbidity worldwide, currently it lacks effective therapies to improve the prognosis. This study was aimed to explore the role of bone marrow mesenchymal stem cells (BMSCs) transplantation in the recovery of brain structure and function after ischemic cerebral infarction by magnetic resonance imaging (MRI).
Methods: By applying internal carotid artery embolization, the ischemic cerebral infarction model in rats was established. MRI was performed to detect the imaging changes in the brain tissue after modeling, and the successful modeling was evidenced by the presence of obvious high-signal infarct areas in the brain. BMSCs were then injected into the lateral ventricles of rats, and the recovery of brain tissue and function were quantitatively evaluated by T2-weighted image (T2WI) and voxel-based morphology (VBM) after 28 days.
Results: The results showed that BMSCs were cell subsets with multiple differentiation potentials. Deficits caused by Ischemic cerebral infarction were relieved by BMSCs transplantation, including increase in damaged cerebral tissue and recovery of cerebral function. In addition, the combined imaging technology of VBM and T2WI quantitatively revealed the effectiveness of BMSCs in repairing damaged brain tissue structure and function.
Conclusion: Taken together, the results revealed that the transplantation of BMSCs into the lateral ventricle was beneficial to repair the structure and function of the damaged brain tissue after ischemic cerebral infarction. Moreover, the combination of VBM and T2WI technology can detect the level of brain injury in ischemic cerebral infarction dynamically and noninvasively, and evaluate the recovery of structure and function of damaged brain tissue.

Delayed cerebral ischemia, one of the most common complications following aneurysmal subarachnoid hemorrhage, was strongly related to poor patient outcomes. However, there are currently no clear guidelines to provide clinical guidance for post-craniotomy management. Our research aims to explore the association between cumulative blood pressure exposure during the early brain injury phase and the occurrence of delayed cerebral infarction and rebleeding following surgical aneurysm clipping.

The article presents theses of the resolution of the Interdisciplinary Council of Experts in Psychiatry and Neurology (Moscow, 2024) on the issue of comorbid anxiety disorders (AD) in patients with neurological pathologies. The authors highlight the high prevalence of comorbid ADs and their significant negative impact on the course of underlying diseases, such as epilepsy, pain syndromes and post-stroke conditions. Modern approaches to the diagnosis and treatment of ADs in this group of patients are discussed.

At the present stage, great progress has been achieved in understanding the mechanisms of the development of cerebral ischemia. This became possible due to the achievements of theoretical disciplines, in connection with which the general biological approach was formed in the study of pathogenesis of acute and chronic cerebrovascular disorders (CVD). The discovery of pathways of free radical oxidation in cerebral ischemia made it possible to substantiate and develop therapeutic strategies using drugs with antioxidant and neuroprotective activity.

Chronic cerebral ischemia (CCI) is one of the most common forms of cerebrovascular disease, which affects a significant number of patients, often leading to disability, cognitive impairment and dementia. The analysis of modern data on the pathogenesis and risk factors for the development of CCI, as well as on the mechanisms of action of Mexidol on various links in the pathogenesis of CCI. A systematic search was conducted in the PubMed, MEDLINE and Google Scholar databases, on Russian and English-language sites with open access publications on the problem of CCI and on the drug Mexidol in the period from 2014 to 2024.

Background: Lung transplantation is a viable lifesaving option for patients with diffuse pulmonary arteriovenous malformations (AVMs). We present a case of diffuse pulmonary AVMs associated with juvenile polyposis and hereditary hemorrhagic telangiectasia (JP-HHT) that was successfully managed by lung transplantation.
Case Presentation: A 19-year-old woman developed severe hypoxemia due to pulmonary AVMs diagnosed at 4 years of age.
