Neural induction is the first step in the formation of the vertebrate central nervous system. The emerging consensus of the mechanisms underlying neural induction is the combined influences from inhibiting bone morphogenetic protein (BMP) signaling and activating fibroblast growth factor (FGF)/Erk signaling, which act extrinsically via either autocrine or(More)
During embryogenesis, the Activin/Nodal pathway promotes the mesendodermal lineage and inhibits neural fate. The molecular mechanisms underlying this role of the Activin/Nodal pathway are not clear. In this study, we report a role for protein tyrosine phosphatase 1B (PTP1B) in Activin-mediated early fate decisions during ESC differentiation and show that(More)
OBJECTIVES Gilbert's syndrome is a congenital, nonhemolytic, unconjugated hyperbilirubinemia. The most common genotype of Gilbert's syndrome is the homozygous polymorphism, A(TA)7TAA, in the promoter of the gene for UDP-glucuronosyltransferase 1A1 (UGT1A1), with a thymine adenine insertion in the TATA-box-like sequence, which results in a decrease in UGT1A1(More)
Neural development from blastocysts is strictly controlled by intricate transcriptional programmes that initiate the down-regulation of pluripotent genes, Oct4, Nanog and Rex1 in blastocysts followed by up-regulation of lineage-specific genes as neural development proceeds. Here, we demonstrate that the expression pattern of the transcription factor Rest(More)
Acute pulmonary embolism as the first manifestation of hepatocellular carcinoma (HCC) complicated with tumor thrombi in the inferior vena cava (IVC) and right atrium is rare [1]. These patients usually die within a short period because of pulmonary embolism, heart failure, or cancer progression [2]. Here, we describe a 57-year-old man who had HCC(More)
Acute pancreatitis is a condition that leads to destruc-tionand necrosis of pancreatic tissue and frequentdevelopment of multiple organ failure. Most cases arerelated to gallstones or heavy alcohol intake. Amongthe numerous other causes are hypertriglyceridemia,hypercalcemia, abdominal trauma, drugs, vasculitis, viralinfection, peritoneal dialysis,(More)
OBJECTIVE The major characteristics of spontaneous intracranial hemorrhage (SICH) in cirrhotic patients have not been completely defined. Cirrhotic patients with SICH were thus analyzed in an effort to better understand the risk factors for SICH and predict patient outcomes. PATIENTS AND METHODS From 1997 to 2006, 4515 hospitalized cirrhotic patients were(More)
OBJECTIVE We report our experience of endoscopy in the emergency management of dietary foreign bodies. METHODS One hundred thirty-six patients were admitted to the emergency department (ED) between January 1997 and October 2006 for the endoscopic removal of esophageal dietary foreign bodies. They had a mean age of 47.7 years, and 91 (67%) were women. (More)
The incidence of Sjögren syndrome (SS) in primary biliary cirrhosis (PBC) patients is high. The influence of SS on the clinical outcomes of PBC patients, however, remains unclear. Our study retrospectively collected data on PBC-only patients and PBC patients with concomitant SS (PBC-SS) to compare the clinical differences of long-term outcomes between(More)
