Is a robotic system really better than the three-dimensional laparoscopic system in terms of suturing performance?
Novices benefited particularly from the robot. The intermediate group completed the task equally well and equally quickly with 3D laparoscopy and the robot. The experts completed the task equally well regardless of instrument, but their times were much faster with 3D laparoscopy. Thus, well-trained laparoscopic surgeons may not really benefit from 3D robot systems if 3D laparoscopy is available.
This study shows for the first time that supplementation with the most abundant green tea polyphenol, EGCG, abolishes diet-induced obesity. This effect is at least partly mediated via a direct influence on adipose tissue. Thus, dietary supplementation with EGCG should be considered as a valuable natural treatment option for obesity.
