OBJECTIVE To determine the most important indicators of prognosis in patients with return of spontaneous circulation (ROSC) following out-of-hospital cardiopulmonary arrest (OHCA) and to develop a best outcome prediction model. DESIGN AND PATIENTS All patients were prospectively recorded based on the Utstein Style in Osaka over a period of 3 years(More)
INTRODUCTION The gut is an important target organ after severe insult. Gut microbiota have an important role in immune response. However, the gut microbiota and environment have not been clarified in patients with burns. Therefore, we serially evaluated the gut microbiota and environment in patients with major burns. METHODS Fecal samples from five(More)
To determine whether the ultrastructural changes in the eyes of an animal model of Vogt-Koyanagi-Harada (VKH) disease are similar to those in human eyes with VKH disease. Pigmented rats derived by crossing brown Norway and Lewis rats were immunized with tyrosinase-family proteins, and the eyes were enucleated after different postinoculation times. The eyes(More)
Small pneumothoraces are often not visible on supine screening chest radiographs because they develop anteriorly to the lung. These pneumothoraces are termed occult. Occult pneumothoraces account for an astonishingly high 52% to 63% of all traumatic pneumothoraces. A 19-year-old obese woman was involved in a head-on car accident. The admission(More)
We clarified the effect of exchange transfusion with liposome-encapsulated hemoglobin (neo red cells, NRCs) with low O₂ affinity (P₅₀O₂ = 50 mm Hg) on O₂ metabolism. Rabbits were randomly assigned to receive serial exchange transfusions with NRC (NRC group, n = 5), shed blood diluted 1:1 with saline (red blood cell (RBC) group, n = 5), or saline alone(More)
BACKGROUND We established a multi-center, prospective cohort that could provide appropriate therapeutic strategies such as criteria for the introduction and the effectiveness of in-hospital advanced treatments, including percutaneous coronary intervention (PCI), target temperature management, and extracorporeal cardiopulmonary resuscitation (ECPR) for(More)
1. Necessity of an Automatic Simulation System For the realization of today's miniaturization and low voltage drive of ULSIs, it has become much more important to understand and predict the effect of process variations on device performance. Predicting the quantitative effect of every process variation o n device characteristics has following advantages: In(More)
