1. Imagine flying inside the buzzing world of a bacterial cell! The journey starts inside your intestinal tract. There a colony of E. coli bacteria helps you to digest your food. We approach one of these bacteria and fly inside. A fascinating world of biological agents awaits: molecules and proteins are filling the cell, displaying a very busy machinery of life.

    We zoom onto an area on the DNA. Here a repressor blocks an RNA polymerase from reading the genetic information. We then observe how genes are regulated. Lactose is entering the cell's interior space. Lactose interacts with the repressor protein, forming a lac-repressor complex. The repressor dissociates from the DNA. Now transcription can start: RNA polymerase makes a DNA copy; strands of messenger RNA are created, which immediately are traced by ribosomes to translate these into chains of amino acids. Those chains fold into proteins: in this case proteins called beta-galactosidase.

    Now you have watched gene expression and gene regulation in action. This is the basic mechanism how different genes are blocked (not accessible for reading) or are expressed into proteins, which then serve as either regulatory units or building blocks for the cell.

  2. In this video we present our first human anatomy app for iPad and iPhone. We discuss the potential of interactive anatomy and physiology, and how such apps contribute to innovation in medical education.

Updates from the LINDSAY Virtual Human project at the University of Calgary, Alberta, Canada.

We develop 3-dimensional, interactive computer models of human anatomy and physiology.

Our interdisciplinary research teams come from both the Faculty of Medicine (Undergraduate Medical Education, Hotchkiss Brain Institute) and the Faculty of Science (Department of Computer Science).
