Performance curve of basic skills in single-incision laparoscopy versus conventional laparoscopy: is it really more difficult for the novice?
This study showed a significant improvement in basic skills for both the SILS and conventional laparoscopy settings after 11 repetitions. These data suggest that box training shows no significant difference between conventional laparoscopic and single-incision laparoscopic settings in terms of error or time in performing basic tasks at a low complexity level for the novice. These data also show significant improvement in basic skills over a relatively short period.
All these compounds were obtained from this genus for the first time. Compound (III), 4-cumylphenol, was a new nature product. All compounds were inactive (IC50 > 10 microg x mL(-1)) in cytotoxicity screening. In inhibition against proliferation of dog vascular smooth muscle cells test, the cell survival ratio to compound I was (0.32 +/- 0.056)% which indicate its potential anti-atherosclerotic bioactivity.
