Abstract:Most drug delivery systems as treatment modalities for osteomyelitis have not been evaluated for resistant infections. Tigecycline (TG) is an antimicrobial agent that could be used in the treatment of multi-drug-resistant orthopedic infections. The objective of this in vitro study has been to determine what dosage of TG causes changes in the morphology and number of osteoblasts. We have also investigated whether nanoparticulate tigecycline-loaded calcium-phosphate/poly-DL-lactide-coglycolide is biocompatible a… Show more
“…[30][31][32][33] The novel concept involving a simultaneous, controlled release of a drug and a prodrug with different physicochemical properties was applied in order to prolong the release period of antibiotics and estimate their high local concentrations, which are the necessary preconditions for the treatment of some chronic infectious diseases. [30][31][32][33][34] Multifunctional nano-particulate HAp-based powders were prepared for the purpose of: a) either fast or sustained, local delivery of cholecalciferol (D 3 ) and b) the secondary, osteoconductive and defect-filling effect of the carrier itself. 35 Synthesized nanoparticles (average particle size, d 50 = 71 nm) of HAp-coated with D 3 loaded PLGA had the zeta potential of -33.4 mV, characteristic for the stable and aggregation-resistant particles.…”

The interdisciplinary research team implemented the program titled "Molecular designing of nanoparticles with controlled morphological and physicochemical characteristics and functional materials based on them" (MODENAFUNA), between 2011 and 2016, gaining new knowledge significant to the further improvement of nanomaterials and nanotechnologies. It gathered under its umbrella six main interrelated topics pertaining to the design and control of morphological and physicochemical properties of nanoparticles and functional material based on them using new methods of synthesis and processing: 1) inorganic nanoparticles, 2) cathode materials for lithium-ion batteries, 3) functional ceramics with improved electrical and optical properties, 4) full density nanostructured calcium phosphate and functionally-graded materials, 5) nano-calcium phosphate in bone tissue engineering and 6) biodegradable micro-and nano-particles for the controlled delivery of medicaments.
