| 1 | Sustained low diffusing capacity in hepatopulmonary syndrome after liver transplantation显示文摘AIM: To study the presence of sustained low diffusing capacity (DLCO) after liver transplantation (LT) in patients with hepatopulmonary syndrome (HPS).METHODS: Six patients with mild-to-severe HPS and 24 without HPS who underwent LT were prospectively followed before and after LT at mid-term (median, 15 mo). HPS patients were also assessed at long-tem (median, 86 mo).RESULTS: Before LT, HPS patients showed lower PaO2 (71 ± 8 mmHg), higher AaPO2 (43 ± 10 mmHg) and lower DLCO (54% ± 9% predicted), due to a combination of moderate-to-severe ventilation-perfusion (VA/Q) imbalance, mild shunt and diffusion limitation, than non-HPS patients (94 ± 4 mmHg and 19 ± 3 mmHg, and 85% ± 3% predicted, respectively) (P < 0.05 each). Seven non-HPS patients had also reduced DLCO (70% ± 4% predicted).At mid- and long-term after LT, compared to pre-LT, HPS patients normalized PaO2 (91 ± 3 mmHg and 87 ± 5 mmHg), AaPO2 (14 ± 3 mmHg and 23 ± 5 mmHg) and all VA/Q descriptors (P < 0.05 each) without changes in DLCO (53% ± 8% and 56% ± 7% predicted, respectively). Post-LT DLCO in non-HPS patients with pre-LT low DLCO was unchanged (75% ± 6% predicted).CONCLUSION: While complete VA/Q resolution in HPS indicates a reversible functional disturbance, sustained low DLCO after LT also present in some non-HPS patients, points to persistence of sub-clinical liver-induced pulmonary vascular changes. | Graciela Martínez-Pallí Federico P Gómez Joan A Barberà Miquel Navasa Josep Roca Robert Rodríguez-Roisin Felip Burgos Conchi Gistau | 2006 | World Journal of Gastroenterology2006，12，36： | 6 |
| 2 | Heat Transfer in Steelmaking Ladle显示文摘The heat transfer in a steelmaking ladle was studied. The evaluation of heat transfer of the steel was performed by measuring steel temperature in points including all refining steel process. In the ladle, the temperatures in the refractories and the shell were also measured. To evaluate the thermal profile between the hot and cold faces of the ladle in the slag line position, an experiment which shows the importance of thermal contact resistance was carried out. Higher heat losses in the tapping and the vacuum were verified. The temperature measurements of the ladle indicate distinct thermal profiles in each stage of steel refining. Moreover, as each stage of the process depends on the previous one, the complexity of the ladle thermal control is incremental. So a complete model of heat losses in the ladle is complex. | André Zimmer lvaro Niedersberg Correia Lima Rafael Mello Trommer Saulo Roca Bragana Carlos Pérez Bergmann | 2008 | Journal of Iron and Steel Research(International)2008，15，3： | 4 |
