Bone marrow mesenchymal stem cells (BMSCs) -derived extracellular vesicles (EVs), especially small EVs (sEVs), were vastly reported to enable multiple restorative effects on ischemic stroke, yet the protective mechanism of blood-brain barrier (BBB) has not been fully illustrated. In the present study, we investigated the therapeutic effects and mechanism of BMSCs-derived sEVs on BBB injury after ischemic stroke. In-vivo, administering sEVs to transient middle cerebral artery occlusion (tMCAo) mice mitigated the brain infarct volume, BBB permeability and neural apoptosis, and improved the cerebral blood flow perfusion and neurological function.

Introduction: The environmental impact of on-site conferences, with air travel as the primary contributor to greenhouse gas emissions, has prompted a surge in research in recent years. The objective of this report is to raise awareness and stimulate transformation in the organisation of meetings of the European Health Psychology Society (EHPS).
Methods: We conducted estimations of travel-related COeq emissions of EHPS conferences in 2019, 2022, and 2023, and performed projections for 2024 and 2025.
Intracerebroventricular anaerobic dopamine in Parkinson's disease with L-dopa-related complications: a phase 1/2 randomized-controlled trial.

Continuous compensation for cerebral dopamine deficiency represents an ideal treatment for Parkinson's disease. Dopamine does not cross the digestive and blood-brain barriers and is rapidly oxidized. The new concept is the intracerebroventricular administration of anaerobic dopamine (A-dopamine) using an abdominal pump connected to a subcutaneous catheter implanted in the third ventricle, near the striatum.

Fungal infections are a major contributor to mortality for people with HIV/AIDS. Recently, researchers, clinicians, industry experts, and policymakers convened for the triennial AIDS-Related Mycoses Meeting to address critical gaps in the management of AIDS-related mycoses. Delegates highlighted several scientifically driven milestones that have significantly reduced fungal-related deaths, and the need to address outstanding challenges in diagnosis, treatment, and research.
