Background and Objective: As one of the widely used drugs, aspirin (acetyl-salicylic acid, ASA) plays an important role in stroke treatment and prevention. In a previous study, we demonstrated ASA injection at 30 min after ischemia onset is neuroprotective. To determine whether the neurons protected by ASA had a normal ultrastructure, hippocampal CA1 pyramidal neurons were examined by Transm...

objective(s) the brief interruption of cerebral blood flow causes permanent brain damage and behavioral dysfunction. the hippocampus is highly vulnerable to ischemic insults, particularly the ca1 pyramidal cell layer. there is no effective pharmacological strategy for improving brain tissue damage induced by cerebral ischemia. previous studies reported that pentoxifylline (ptx) has a neuroprote...

Duchesnea indica (D. indica) is an important traditional Chinese medicine, and has long been clinically used to treat cancer in Asian countries. It has been described previously as a rich source of phenolic compounds with a broad array of diversified structures, which are the major active ingredients. However, an accurate and complete phenolic profiling has not been determined yet. In the prese...

the prevention of bbb breakdown and the subsequent vasogenic edema are important parts of the medical management of ischemic stroke. the purpose of this study was to investigate the ischemic tolerance effect of rosmarinus officinalis leaf hydro-alcoholic extract (rhe).five groups of animals were designed: sham (underwent surgery without mcao) and mcao groups, the mcao groups were pretreated ora...

The compounds Gallic acid (GA), rutin(R), quercitin (Q), ellagic acid (EA) and sitosterol(S) were isolated from the methanolic extract of the leaves of Tectona grandis. These compounds were subjected to antimicrobial and antioxidant activity. The zone of inhibition of isolated compounds was evaluated by cup plate method against bacteria i.e. Staphylococcus aureus, Bacillus subtilis, Eschericia ...

objectives in this study, we aimed to investigate the changes in brain lipidomics following prolonged and intermittent ischemic preconditioning. materials and methods two groups underwent bilateral common carotid artery occlusion either intermittently (for 3 continuous periods within a timeframe of 20 minutes, releasing 3 consecutive times, yielding a total of 9 minutes (intermittent bilateral ...

Lactate is an intriguing molecule with emerging physiological roles in the brain. It has beneficial effects animal models of acute brain injuries and traumatic injury or subarachnoid hemorrhage patients. However, mechanism by which lactate provides protection unclear. While there evidence a metabolic effect providing energy to deprived neurons, it can also activate hydroxycarboxylic acid recept...
