a simple special protocol using semichon’s acetic carmine stain was applied for examination of muscles of some small mammals, naturally infected with sarcocystis spp. using this method, infected muscles fibers with sarcocystis could easily be differentiated from muscle tissues. this method can be applied for screening of infected muscles with sarcocystis cysts on large number of samples for epi...

The side population (SP) assay, a technique used in cancer and stem cell research, assesses the activity of ABC transporters on Hoechst staining in the presence and absence of transporter inhibition, identifying SP and non-SP cell (NSP) subpopulations by differential staining intensity. The interpretation of the assay is complicated because the transporter-mediated mechanisms fail to account fo...

This report describes a technique for the differential staining of the two types of nucleoproteins in bacteria. The staining procedure is adapted from that described by Jacobson and Webb (1952) for other cells. In several respects it is similar to techniques previously used in bacterial cytology. Visualization of the two nucleoproteins individually is possible after treatment with specific nucl...

Biological monitoring of early genotoxic effects in urothelial cells using the urinary micronucleus (MNu) assay is promising for early detection of cancer, such as bladder carcinoma. But many problems are encountered, the major being the poorly differential staining of cells, particularly in women having an important amount of squamous cells. We have optimized the protocol and obtained a differ...
