Despite numerous studies on the neural basis of numerical processing, few studies have examined the neural substrates of one of the most basic numerical processing-number sequence recitation. The present study used fMRI to investigate neural substrates of number sequence recitation, focusing on the intraparietal sulcus (IPS) and perisylvian areas. This(More)
Recently, a significant epigenetic component in the pathogenesis of Coronary Artery Disease (CAD) has been realized. Here, we evaluated the possible association of candidate Single Nucleotide Polymorphisms (SNPs) in the epigenetic-regulatory gene, DNA methyltransferase 1 (DNMT1), with CAD in Chinese Han population. Five tag SNPs (rs16999593, rs2336691,(More)
Age, gender, diet, gene and lifestyle have been reported to affect metabolic status and disease susceptibility through epigenetic pathway. But it remains indistinct that which factors account for certain epigenetic modifications. Our aim was to identify the influencing factors on inter-individual DNA methylation variations of carbohydrate response element(More)
Aging is a complex phenomenon and characterized by a progressive decline in physiology and function of adult tissues. However, it hasn’t been well established of the correlation between aging and global DNA methylation and hydroxymethylation that regulate the growth and development of higher organisms. We developed an on-line trapping/capillary(More)
BACKGROUND AND OBJECTIVES Pancreatic cystic neoplasms (PCNs) are being increasingly identified. Recent reports have described the utility of endoscopic ultrasound (EUS) in the characterization of PCNs. This study presents the diagnostic value of EUS in PCNs. MATERIALS AND METHODS A total of 108 patients (78 women and 30 men; average age, 50 years) who(More)
Endoscopic balloon dilation combined with stenting has been increasingly used in managing biliary anastomotic strictures (BAS) after orthotopic liver transplantation (OLT). However, data on the efficacy and safety vary among different studies. To obtain reliable estimates for the efficacy and safety of this endoscopic combination therapy in post-OLT BAS. A(More)
BACKGROUND Success in deep biliary cannulation via native ampullae of Vater is an accepted measure of competence in ERCP training and practice, yet prior studies focused on predicting adverse events alone, rather than success. Our aim is to determine factors associated with deep biliary cannulation success, with/ without precut sphincterotomy. METHODS The(More)
Small cell carcinoma of the gastrointestinal tract is a rare and aggressive neuroendocrine tumor. This study aims to analyze the clinical characteristics and potential prognostic factors for patients with limited stage small cell carcinoma of the gastrointestinal tract. The records of 27 patients with limited stage small cell carcinoma of the(More)
