Astrocytes help protect neurons from potential damage caused by reactive oxygen species (ROS). While ROS can also exert beneficial effects, it remains unknown how neuronal ROS signalling is activated during memory formation, and whether astrocytes play a role in this process. Here we discover an astrocyte-to-neuron HO signalling cascade in Drosophila that is essential for long-term memory formation.

Biomagnetic fluid dynamics (BFD) is an emerging and promising field within fluid mechanics, focusing on the dynamics of bio-fluids like blood in the presence of magnetic fields. This research is crucial in the medical arena for applications such as medication delivery, diagnostic and therapeutic procedures, prevention of excessive bleeding, and treatment of malignant tumors using magnetic particles. This study delves into the intricacies of blood flow induced by cilia, carrying trihybrid nanoparticles (gold, copper, and titania), within a catheterized arterial annulus under a robust magnetic field.

The therapeutic effects of probiotics in patients with traumatic brain injury (TBI) remain unclear. This study aimed to investigate the effects of probiotic supplementation on cell adhesion molecules, oxidative stress, and antioxidant parameters in TBI patients. This randomized, double-blind, placebo-controlled trial included 46 TBI patients who were randomly assigned to receive either a probiotic supplement (n = 23) or a placebo (n = 23) for 14 days.

Copper accumulation in the basal ganglia, disrupts dopaminergic pathways, contributing to dystonia's development via neurotransmitter imbalance. Despite advances in diagnosis and management, WD with dystonia remains a challenging condition to treat.

Background And Purpose: Cerebral amyloid angiopathy (CAA) is recognized as a major contributor to progressive cognitive decline and cerebral hemorrhages in the elderly population. Currently, there is a global shortage of safe and effective treatments for this condition. Bisdemethoxycurcumin (BDMC) has been demonstrated to exhibit pharmacological effects with anti-Aβ toxicity properties.
