[Short-term effectiveness of anterior cruciate ligament reconstruction with LARs artificial ligament]. |
OBJECTIVE |
To investigate the surgical technique and short-term effectiveness of anterior cruciate ligament (ACL) reconstruction with LARS artificial ligament. |
METHODS |
Between November 2008 and April 2010, eighty patients with ACL injury were treated with LARS artificial ligament under arthroscope and successfully followed up. There were 51 males and 29 females, aged from 17 to 43 years with an average of 29.2 years. The injuries were caused by sport in 63 cases, traffic accident in ... |
RESULTS |
All incisions healed by first intention without complication of infection or deep venous thrombosis. All patients were followed up 7 to 24 months with an average of 16.8 months. There were 3 cases of screws exposure toward femoral cortical bone, 2 cases of loosening tibial screw, and 1 case of knee extension limitation... |
CONCLUSION |
The viscoelastic properties of LARS artificial ligament is different from that of biological materials. The graft should be fixed at a relatively extension position to avoid knee extension limitation and slight loosening of graft tension is permitted at flexion position. Good clinical result could be achieved if the te... |
Homogeneity of within-subgroup error variance is a necessary condition for using multiple regression to estimate moderating effects of categorical variables. A 12-year review of Academy of Management Journal, Journal of Applied Psychology, and Personnel Psychology indicates that the assumption is violated in 40% to 60%... |
PURPOSE |
To quantitatively evaluate and validate a two-phase helical computed tomographic (CT) protocol for evaluation of pancreatic tumors. |
MATERIALS AND METHODS |
Twenty-seven patients with pathologically proved pancreatic adenocarcinomas prospectively underwent two-phase CT examination with helical acquisition during the pancreatic phase (40-70 seconds after infusion of intravenous contrast material at 3 mL/sec) and the hepatic phase (70-100 seconds after infusion). Mean CT att... |
RESULTS |
Mean tumor-pancreas contrast was significantly greater during the pancreatic phase (67 HU +/- 19) than the hepatic phase (39 HU +/- 16) (P < .001) This was the result of both greater enhancement of normal pancreas and lower tumor enhancement during the pancreatic phase. Opacification of all vascular structures, includi... |
CONCLUSION |
Two-phase helical CT with pancreatic phase acquisition provides statistically significantly better pancreatic, arterial, and portal venous enhancement than that of hepatic phase imaging, with improved tumor-pancreas contrast.Stability issues of conjugated polymer/fullerene solar cells from a chemical viewpoint |
The efficiency of energy conversion and the stability of lifetime of `plastic' photovoltaic cells, based on conjugated polymer/fullerene blends, are the two main issues to be improved for this type of devices. The stability of these PV cells depends potentially on a large number of factors. A brief layer-to-layer overv... |
