objective:at the present study, relationship between phagocytosis of plga particles and combined effects of particle size and surface pegylation was investigated.  materials and methods:microspheres and nanospheres (3500 nm and 700 nm) were prepared from three types of plga polymers (non-pegylated and pegylation percents of 9% and 15%). these particles were prepared by solvent evaporation metho...

objective(s):the objective of this study was to determine the cytotoxic effects of nanoliposomal form of lyophilized aqueous extract of agrostemma githago (a. githago) seeds on gastric cancer cell line (ags) using cell viability tests. materials and methods: lyophilized aqueous extract of a. githago seeds was prepared. liposomes were also prepared by thin-film hydration method and their stabili...

Cells are able to adjust their growth and size to external inputs to comply with specific fates and developmental programs. Molecular pathways controlling growth also have an enormous impact in cell size, and bacteria, yeast, or epithelial cells modify their size as a function of growth rate. This universal feature suggests that growth (mass) and proliferation (cell number) rates are subject to...
