Comparison of short- and long-term outcomes of an early experience with robotic and laparoscopic-assisted resection for rectal cancer.

BACKGROUND/AIMS: Robotic surgery is increasingly used for rectal cancer. We compared the short- and long-term outcomes between robotic- and laparoscopic-assisted resection for rectal cancer.

On the Origins of Hepatitis C Virus NS5B Polymerase Inhibitory Activity Using Machine Learning Approaches.

Inhibition of non-structural protein 5B (NS5B) represents an attractive strategy for the therapeutic treatment of hepatitis C virus (HCV). In this study, machine learning classifiers such as artificial neural network (ANN), support vector machine (SVM), random forest (RF) and decision tree (DT) analyses were used to classify 970 compounds based on their physicochemical properties, including quantu...
