This product demonstration video, from Leica Microsystems and myNeurolab.com, illustrates usage of the innovative Leica Angle Two™ computer-guided stereotaxic instrument for mouse, rat and other lab animals. The Angle Two™ allows neuroscientists to be more precise and repeatable in targeting specific brain locations; thus reducing animal costs. Charles Scouten, PhD, Product & Innovation Manager at Leica Microsystems, guides the viewer step-by-step through the usage of this unique stereotaxic instrument.
Swiss microbial geneticist, Werner Arber shared the 1978 Nobel Prize in Physiology or Medicine with Hamilton Smith and Daniel Nathans for their discovery of restriction endonucleases. Arber found that viral DNA introduced into a non-specific bacterial host was changed, while host DNA was protected by methylation. He theorized that a microbial enzyme cut the DNA into smaller pieces, while at the same time, the methylated host DNA was protected from its own enzymes. Later work done by Nathans and Smith validated his theory, which laid the foundation for recombinant DNA technology.
Right Hemihepatectomy by Suprahilar Intrahepatic Transection of the Right Hemipedicle using a Vascular Stapler
This video describes a right hemihepatectomy with intrahepatic transection of the right hemipedicle leaving the hepatoduodenal ligament completely untouched.
In this video, we demonstrate a method for electrophoretic separation of proteins using poly-acrylimide gel electrophoresis (PAGE).
This third issue of JoVE draws attention to issues on the intersection of the basic and applied biomedical research. In this context, the interview with Ole Isacson (McLean Hospital/Harvard Medical School) provides an in-depth look at contemporary challenges of Parkinson’s disease research. The candid interview grants insights that reach beyond the pure scientific problems, as it addresses...

We report the development of a system for automated imaging and analysis of zebrafish transgenic embryos in multiwell plates. This demonstrates the ability to measure dose dependent effects of a small molecule, BCI, on Fibroblast Growth Factor reporter gene expression and provide technology for establishing high-throughput zebrafish chemical screens.

Silver nanowires can simultaneously transport electrons and optical information in the form of surface plasmons. A procedure is described here to realize such a shared circuitry and the limitations at propagating both information carriers are evaluated.
