Neurosurgical Operative Videos: An Analysis of an Increasingly Popular Educational Resource.

Objective: Surgical education has increasingly relied on electronic learning. In particular, online operative videos have become a core resource within neurosurgery. We analyze the forums for neurosurgical operative videos.

Effect of Loading Method on a Peptide Substrate Reporter in Intact Cells.

Studies of live cells often require loading of exogenous molecules through the cell membrane; however, effects of loading method on experimental results are poorly understood. Therefore, in this work, we compared three methods for loading a fluorescently labeled peptide into cells of the model organism Dictyostelium discoideum. We optimized loading by pinocytosis, electroporation, and myristoylation to maximize cell viability and characterized loading efficiency, localization, and uniformity.

Synthetic Strategies Employed for the Construction of Fostriecin and Related Natural Products.

Fostriecin and related natural products present a significant challenge for synthetic chemists due to their structural complexity and chemical sensitivity. This review will chronicle the successful efforts of synthetic chemists in the construction of these biologically active molecules. Key carbon-carbon bond forming reactions will be highlighted, as well as the methods used to install the numerous stereocenters present in this class of compounds.
