Obvious Reason

In the 1940's and 1950's electron microscopy conferences were attended with everybody interested in learning about the latest technical developments for one very obvious reason. There was the electron microscope with its outstanding performance but nobody could make very much use of it because we were lacking proper techniques to prepare biological specimens. The development of the thin sectioning technique with its perfectioning in 1952 changed the situation and systematic analysis of the structure of cells could now be pursued. Since then electron microscopists have in general become satisfied with the level of resolution at which cellular structures can be analyzed when applying this technique. There has been little interest in trying to push the limit of resolution closer to that determined by the resolving power of the electron microscope.

The Future

AbstractThe digital media becomes more and more common in our everyday lives. So it is not surprising that technical progress is also leaving its mark on amblyopia therapy. New media and technologies can be used both in the actual amblyopia therapy or therapy monitoring. In particular in this review shutter glasses, therapy monitoring and analysis using microsensors and newer video programs for amblyopia therapy are presented and critically discussed. Currently, these cannot yet replace classic amblyopia therapy. They represent interesting options that will occupy us even more in the future.

The concept of downsized catheters (i.e., using catheters smaller than 6 French) for invasive coronary procedures, such as diagnostic cardiac catheterisation and percutaneous coronary intervention, has been developing over the years, particularly as a result of the rise of the transradial approach. Recent advances have allowed the use of smaller and sheathless catheters, which confer a number of advantages – such as fewer vascular complications, reduced use of contrast agent and reduced haemostasis – thus increasing patient safety and comfort and allowing more rapid patient mobilisation. Reductions in patient complications, number and length of hospital stay, and amount of contrast agent used can also lead to cost savings. While the use of smaller catheters has been hindered in the past because of poor angiographic image quality, new automated contrast injectors have helped overcome this limitation. There is a need to make interventional cardiologists worldwide more aware of the benefits of downsizing, in the light of the latest technical developments and the increased use of transradial approach.
