The world wide proliferation of mobile phones raises the concern about the health effects of 1800-MHz microwaves on the brain. The present study assesses the effects of microwave exposure on the function of cultured hippocampal neurons of rats using whole cell patch-clamp analysis combined with immunocytochemistry. We showed that chronic exposure (15 min(More)
β-amyloid (Aβ) oligomers have been closely implicated in the pathogenesis of Alzheimer's disease (AD). We found, for the first time, that bis(heptyl)-cognitin, a novel dimeric acetylcholinesterase (AChE) inhibitor derived from tacrine, prevented Aβ oligomers-induced inhibition of long-term potentiation (LTP) at concentrations that did not interfere with(More)
Rosiglitazone has been known to attenuate neurodegeneration in Alzheimer's disease (AD), but the underlying mechanisms remain unclear. In this study, Morris water maze test, ELISA and electrophysiological methods were used to examine the role and underling mechanisms of rosiglitazone on Aβ42 oligomer-induced memory impairments. We found that rosiglitazone(More)
Rosiglitazone has been known to attenuate neurodegeneration in Alzheimer's disease (AD), but the underlying mechanisms remain to be fully elucidated. In this study, living-cell image, immunocytochemistry, and electrophysiology were used to examine the effects of soluble amyloid-β protein (Aβ) oligomers and rosiglitazone on the synapse formation, plasticity,(More)
Niemann-Pick disease type C (NPC) is a progressive neurodegenerative disorder characterized by accumulation of free cholesterol in late endosomes/lysosomes. The pathological basis for the disease has been poorly understood yet. In our previous study, we have demonstrated that synaptic function is impaired in this disease. In the current study,(More)
BACKGROUND Tim4 is a transmembrane protein known as T cell immunoglobulin and mucin domain containing protein-4. We speculated that Tim4 might be associated with glioma. This study aimed to investigate the expression level of Tim4 in gliomas and the regulatory role of Tim4 on the growth and apoptosis of LN-18 glioma cells. MATERIAL/METHODS Tumor tissues(More)
17β-Estradiol (E2) is hydrolyzed to 2-hydroxy-E2 and 4-hydroxy-E2 (4-OH-E2) via cytochrome P450 (CYP) 1B1. In estrogen target tissues including the mammary gland, ovaries and uterus, CYP1B1 is highly expressed, and 4-OH-E2 is predominantly formed in cancerous tissues. In the present study, we investigated the inhibitory activity of α-naphthoflavone and(More)
To assess the effectiveness of continuous lumbar drainage (LD) for management of postoperative cerebrospinal fluid leaks after endoscopic endonasal transsphenoidal approach for resection of pituitary adenoma. Three hundred eighty-four medical records of patients who were admitted to our institute during a 2.5-year period were retrospectively reviewed, 33 of(More)
Glioblastoma multiforme (GBM) is a type of malignant carcinoma found in the brain. Its high frequency of occurrence and poor survival rate have garnered much research attention in recent years. Long non-coding RNAs (lncRNAs) are known to be related to the formation and progression of several cancer types by both promoting and suppressing tumor(More)
