N-stearoyltyrosine (NsTyr), a synthesized anandamide (AEA) analogue, was evaluated for the first time in the present study for the neuroprotective effect in gerbils subjected to transient global cerebral ischemia reperfusion (IR). The extent of ischemia injury was assessed behaviorally by measuring neurological functions, passive avoidance test and Morris(More)
beta-Amyloid peptide (Abeta), the major pathological factor in Alzheimer's disease, has recently been reported to be implicated in the development of glaucoma. In this study, we explored the effect of muscarinic activation on abnormal processing of beta-amyloid precursor protein (APP) induced by a risk factor hypoxia in retinal ganglion cells. Hypoxia(More)
Alzheimer's disease (AD) is a progressive neurodegenerative disease characterized by the accumulation of β-sheet-rich amyloid oligomers or fibrils which are associated with cellular toxicity in the brain. Inhibition of Aβ aggregation could be a viable therapeutic strategy for slowing and/or preventing the progress of AD. Here we reported that α-mangostin(More)
Two new polyketides: 2Z-(heptadec-12-enyl)-4-hydroxy-3,4,7,8-tetrahydro-2H-chromen-5(6H)-one (1) and 2-(heptadec-12-enyl)-5-hydroxy-5,6,7,8-tetrahydrochromen- 4-one (2), together with eleven known compounds: 4-hydroxy-2-[(3,4-methylenedioxy- phenyl)tridecanoyl] cyclohexane-1,3-dione (3), oleiferinone (4), 4-hydroxy-2-[(3,4-(More)
Latanoprost, a synthetic derivative of the natural prostaglandin F(2a) (PGF(2a)), is a powerful antiglaucoma agent with ocular hypotensive and neuroprotective effects. However, the neuroregenerative effect and signaling pathway of latanoprost in retinal ganglion cells (RGCs) are still unknown. The purpose of this study is to investigate the regenerative(More)
AIM To compare the effects of ketamine, midazolam, thiopental, and propofol on brain ischemia by the model of oxygen-glucose deprivation (OGD) in rat cerebral cortical slices. METHODS Cerebral cortical slices were incubated in 2 % 2,3,5-triphenyltetrazolium chloride (TTC) solution after OGD, the damages and effects of ketamine, midazolam, thiopental, and(More)
The retina is the most metabolically active tissue in the human body and hypoxia-induced retinal ganglion cell (RGC) death has been implicated in glaucomatous optic neuropathy. The aim of this study is to determine whether muscarinic receptor agonist pilocarpine, a classic antiglaucoma drug, possesses neuroprotection against cobalt chloride(More)
AIMS Muscarinic acetylcholine receptor agonist pilocarpine reduces intraocular pressure (IOP) of glaucoma mainly by stimulating ciliary muscle contraction and then increasing aqueous outflow. It is of our great interest to know whether pilocarpine has the additional properties of retinal neuroprotection independent of IOP lowering in vitro and in vivo(More)
Alzheimer's disease (AD) is a multifaceted neurodegenerative disorder which is characterized by the progressive deterioration of cognition and the emergence of behavioral and psychological symptoms in aging patients. Given that the clinical effectiveness of acetylcholinesterase inhibitors (AChEIs) has still been questioned due to dubious disease-modifying(More)
