objective(s): the aim of this work was to prepare and characterize magnetic nanoparticles (mnps) as theranostic system to act simultaneously as drug carrier and mri contrast agent. chitosan-coated mnps (cmnps) were prepared and loaded with silymarin. silymarin-loaded cmnps were characterized with various techniques and their potential as mri contrast agent was also evaluated. materials and meth...

Advances in biomimetic three-dimensional (3D) melanoma models have brought new prospects of drug screening and disease modeling, since their physiological relevancy for recapitulating vivo tumor architectures is more accurate than traditional two-dimensional (2D) cell culture. Gelatin methacryloyl (GelMA) widely used as a tissue-engineered scaffold hydrogel 3D In the present study, an vitro mal...

objective(s): in this study, drug loaded electrospun nanofibrous mats were prepared and drug release and mechanism from prepared nanofibers were investigated.  materials and methods: paclitaxel (ptx) loaded polylactic acid (pla) nanofibers were prepared by electrospinning. the effects of process parameters, such as ptx concentration, tip to collector distance, voltage, temperature and flow rate...

Rat mesenchymal stem cells (rMSCs) represent a small portion of the cells in the stromal compartment of bone marrow and have the potential to differentiate into bone, cartilage, fat, and fibrous tissue. These mesenchymal progenitor cells were maintained as primary isolates and as subcultured cells in separate closed modular incubator chambers purged with either 95% air and 5% CO(2) (20% or cont...

Angiogenic biomaterials are designed to promote vascularization and tissue regeneration. Nanoparticles of bioactive materials loaded with drugs represent an interesting strategy stimulate osteogenesis angiogenesis inhibit bone resorption. In this work, porcine endothelial progenitor cells (EPCs), essential for blood vessel formation, were isolated characterized evaluate the in vitro effects unl...
