Knyazkov-Dele Bodies in Neutrophils: Morphology and Significance
What Knyazkov-Dele bodies in neutrophils mean during blood smear microscopy. Morphological features, composition of inclusions, and connection to infections and inflammation.
Blood and bone marrow morphology, clinical cases and diagnostic algorithms. Most of the library is in Russian; the English section is growing.
Most of our material is written in Russian — that is the working language of the community. A few pieces exist in English; the rest of the library is one click away and the photographs need no translation.
