Alzheimer's disease (AD) is characterized by the accumulation of β-amyloid peptide (Aβ) and loss of neurons. Recently, a growing body of evidences have indicated that as a herbal compound naturally derived from grapes, resveratrol modulates the pathophysiology of AD, however, with a largely unclear mechanism. Therefore, we aimed to investigate the(More)
New insecticides are urgently needed because resistance to current insecticides allows resurgence of disease-transmitting mosquitoes while concerns for human toxicity from current compounds are growing. We previously reported the finding of a free cysteine (Cys) residue at the entrance of the active site of acetylcholinesterase (AChE) in some insects but(More)
Studies have shown that stem cells exert their therapeutic effects on acute kidney injury (AKI) through paracrine/endocrine actions. If the protective effect is mediated in an endocrine manner, the injection of the factors that these cells secrete could be effective, but the effect of conditioned medium (CM) remains controversial. In this study, we cultured(More)
The aims of the study were to show the direct effect of nicotine with different concentrations (0, 25, 50, and 100 ng/ml) on chondrocytes isolated from normal human and osteoarthritis patients, respectively. Microscopic observation was performed during the culture with an inverted microscope. Methyl thiazolyl tetrazolium (MTT) assay method was adopted to(More)
Although many agents have therapeutic potentials for central nervous system (CNS) diseases, few of these agents have been clinically used because of the brain barriers. As the protective barrier of the CNS, the blood-brain barrier and the blood-cerebrospinal fluid barrier maintain the brain microenvironment, neuronal activity, and proper functioning of the(More)
SDF-1/CXCR4 signalling plays an important role in neuronal cell migration and brain development. However, the impact of CXCR4 deficiency in the postnatal mouse brain is still poorly understood. Here, we demonstrate the importance of CXCR4 on cerebellar development and motor behaviour by conditional inactivation of Cxcr4 in the central nervous system. We(More)
Amyloid-β peptides such as Aβ1-42 (Aβ42) play a pivotal role in the progression of Alzheimer's disease (AD). Aβ42 is neurotoxic and can activate microglial cells. These cells in turn migrate toward senile (neuritic) plaques and help to clear Aβ deposits through an endocytotic mechanism. It is of potential significance to characterize the Aβ42 receptors that(More)
