The development of low-traumatic surgical drains aimed at maximum possible separation blood and air, is an important trend in modern medicine. objective this work to create inexpensive, user-friendly dynamic aspiration system (DBAS). allows effective air when drawing from a wound under vacuum conditions required for aspiration. operating principle the separate liquid gas fractions blood-air mix...

It was observed previously in these laboratories1 that cells and cell fractions from human and animal leukemia when introduced onto the chorioallantoic membranes of embryonated chick eggs produced severe toxicity to embryonic and extra-embryonic tissues, with mortality in a high percentage (50-100%) of inoculated eggs. In marked contrast to these observations, similarly implanted cells and cell...

The protein corona formed around nanoparticles in protein-rich fluids plays an important role for nanoparticle biocompatibility, as found in several studies during the last decade. Biological fluids have complex compositions and the molecular components interact and function together in intricate networks. Therefore, the process to isolate blood or the preparation of blood derivatives may lead ...

Glycophorin A (GPA), the major sialoglycoprotein of human erythrocyte membranes, was isolated separately from blood group A and B erythrocytes using phenol-water extraction. After purification, performed as gel filtration in the presence of SDS, two glycophorin samples GPA-A and GPA-B were run, in duplicate, in SDS-PAGE and electroblotted onto Immobilon P. After staining with 1) anti-glycophori...
