Pistachios have attracted researchers’ attention because they naturally bring together several nutrients and plant compounds connected to sleep. Now, a new narrative review* published in Nutrition Research Reviews identifies pistachios as a promising whole food for sleep research and explores how their nutrient profile may influence processes related to sleep quality, falling asleep, staying asleep and regulation of the sleep–wake cycle. 

The human dental pulp stem cell (hDPSC) secretome, enriched in neurotrophic, antioxidant, and immunomodulatory factors, shows strong therapeutic promise. A new study suggests that the hDPSC secretome may support functional recovery after ischemic stroke. In cell and animal models, treatment reduced oxidative stress, neuroinflammation, and neuronal apoptosis while promoting neurogenesis, vascular remodeling, and synaptic recovery. These molecular and structural changes were accompanied by improved motor performance, spatial learning, and memory-related behaviors.
