Pelletized dosage forms can be prepared by different methods which, in general, are time consuming and labor intensive. The current study was carried out to investigate the feasibility of preparing the spherical pellets of omeprazole by sieving-spheronization. An optimized formulation was also prepared by extrusion-spheronization process to compare the physical parameters between these two meth...
Topologically associating domains (TADs) are fundamental structural and functional building blocks of human interphase chromosomes, yet the mechanisms of TAD formation remain unclear. Here, we propose that loop extrusion underlies TAD formation. In this process, cis-acting loop-extruding factors, likely cohesins, form progressively larger loops but stall at TAD boundaries due to interactions wi...
A study was carried out to clarify the mechanism of nuclear extrusion of mammalian erythroid cells by observing erythroblasts of rabbit under various conditions in vitro. The animals were made anemic by phenylhydrazine injection and erythroblasts were obtained from the peripheral blood and observed morphologically after a certain time of incubation. After two hour incubation at 37 degrees C, ab...
