The embedding does not contribute to the staining of the object nor to the resolving power of the microscope. The best embedding medium permits thin sectioning with the least damage during specimen preparation and give

Biomedical Advances in HIV Preventioneral productivity he knows very well he has to “fix” tissues and cells as a first preparative step. However, he is quite aware that this is basically a crime against nature, and no matter how sophisticated the fixation procedure may be, there surely are always lingering doubts as to how closely the

Douglas Krakower,Kenneth H. Mayeris examined in the electron microscope. There are two advantages compared with earlier techniques. Firstly, fixation and dehydration are not necessary and the replica is thus of cells which differ from the living state only in that they are frozen. (This statement will be qualified later.) Secondly,

Modern Aspects of Electrochemistryxamples in the biological field are radiotherapy (., 1968) and cytology (. et al., 1968). The implementation in electron microscopy is presently developing very fast. The present work gives a review of some experiences in computer analysis of electron microscopic image data, and tries to show some p
