Changes in neural activity caused by exposure to drugs may trigger homeostatic mechanisms that attempt to restore normal neural excitability. In Drosophila, a single sedation with the anesthetic benzyl alcohol changes the expression of the slo K(+) channel gene and induces rapid drug tolerance. We demonstrate linkage between these two phenomena by using a mutation and a transgene. A mutation th...

Takotsubo cardiomyopathy (TC) is a rare reversible circulatory syndrome often detected in elderly patients after general surgery. We report the case of an 85-year-old woman who was admitted for obstructive jaundice and underwent ERCP and ENBD before operation. She finally underwent cholecystectomy and choledocholithotomy with the diagnosis of gallbladder and common bile duct stones. In the even...

Abnormal wall motion detected with exercise echocardiography identifies ischemic myocardium, while normal myocardium exhibits hyperkinetic motion. The normal, hyperkinetic response to exercise is transient and is predictive of an excellent prognosis. However, there are few data on the duration of the hyperkinesis after peak exercise. Our purpose was to determine the time course of wall thickeni...

Case Presentation A 53-year-old Chinese male underwent dobutamine stress echocardiography for evaluation of chest pain. He had a background history of previously treated pulmonary tuberculosis and depression. Baseline left ventricular ejection fraction (LVEF) was normal. At peak intravenous dobutamine infusion of 40 mcg/kg/min, he developed retrosternal chest tightness and his systolic blood pr...
