Image labeling is one solution to such a problem, in which various words are labeled to an image when extracted from a single Web page. Therefore, this(More)
We investigated changes in cytoplasmic Ca2+ concentration ([Ca2+]i) and in left ventricular contractility during sustained ischemia and reperfusion in isolated beating rat hearts. Hearts from male Sprague-Dawley rats were perfused retrogradely and were loaded with 4 μM fura-2. Low-flow global ischemia was induced by reducing perfusion flow to 10% and by(More)
The patient was a 48-year-old man hospitalized for jaundice and anemia after a 6-day history of diarrhea. Examination demonstrated hemolytic anemia, renal dysfunction, and thrombocytopenia. Typical hemolytic uremic syndrome (HUS) was suspected based on the preceding colitis; however, plasma exchange (PE) was performed because the possibility of atypical HUS(More)
Hyperkalemia is prevalent in end-stage renal disease patients, being involved in life-threatening arrhythmias. Although polystyrene sulfonate (PS) is commonly used for the treatment of hyperkalemia, direct comparison of effects between calcium and sodium PS (CPS and SPS) on mineral and bone metabolism has not yet been studied. In a randomized and crossover(More)
