Propofol is a short-acting intravenous anaesthetic agent and widely used not only in operating rooms but also in the intensive care unit (ICU). Apart from its multiple anaesthetic advantages, the neuroprotective effect of propofol has been demonstrated in diverse models of neuronal injury. The effect of propofol results from activation of gamma-aminobutyric acid (GABA) receptor, modulation exci...

In this issue of Stroke, Muir 1 addresses the looming crisis in acute stroke clinical trial design by illustrating why neuroprotective trials have been seriously underpowered. Unfortunately, this is not a new observation. Samsa and Matchar2 pointed out 3 statistical reasons neuroprotective stroke trials have been underpowered: (1) Sensitivity of power to small changes in outcome rates. (2) Over...

As aged population dramatically increases in these decades, efforts should be made on the intervention for curing age-associated neurologic degenerative diseases such as Alzheimer's disease (AD). Caffeoylquinic acid (CQA), an antioxidant component and its derivatives are natural functional compounds isolated from a variety of plants. In this study, we determined the neuroprotective effect of 3,...

BACKGROUND/OBJECTIVES One of the mechanisms considered to be prevalent in the development of Alzheimer's disease (AD) is hyper-stimulation of microglia. Black chokeberry (Aronia melanocapa L.) is widely used to treat diabetes and atherosclerosis, and is known to exert anti-oxidant and anti-inflammatory effects; however, its neuroprotective effects have not been elucidated thus far. MATERIALS/...

Vascular endothelial growth factor (VEGF) is a hypoxia-inducible angiogenic peptide with recently identified neurotrophic effects. Because some neurotrophic factors can protect neurons from hypoxic or ischemic injury, we investigated the possibility that VEGF has similar neuroprotective properties. In HN33, an immortalized hippocampal neuronal cell line, VEGF reduced cell death associated with ...

Oxidative stress is implicated in the pathogenesis of neurodegenerative disorders and hydrogen peroxide (H2O2) plays a central role in the stress. Huprines, a group of potent acetylcholinesterase inhibitors (AChEIs), have shown a broad cholinergic pharmacological profile. Recently, it has been observed that huprine X (HX) improves cognition in non transgenic middle aged mice and shows a neuropr...

Clinical evidence points to neuroprotective effects of smoking in Parkinson's disease (PD), but the molecular mechanisms remain unclear. We investigated the pharmacological pathways involved in these neuroprotective effects, which could provide novel ideas for developing targeted neuroprotective treatments for PD. We used the ETC complex I inhibitor methylpyridinium ion (MPP+) to induce cell de...

INTRODUCTION The anaesthetic agent propofol (2,6-diisopropylphenol) has been shown to be an effective neuroprotective agent in different in vitro models of brain injury induced by oxygen and glucose deprivation. We examined its neuroprotective properties in an in vitro model of traumatic brain injury. METHODS In this controlled laboratory study organotypic hippocampal brain-slice cultures wer...
