Bone-targeted polymeric nanoparticles for alendronate delivery based on Poly (lactic-co-glycolic acid) conjugated chitosan (CS-PLGA) and PLGA (Alen-PLGA) are fabricated their superior performances evaluated. The exhibited sustained Alen release without obvious burst good cytocompatibility against MC3T3 cells. Alen-modified demonstrated a high affinity to hydroxyapatite, which is the main minera...
BACKGROUND Polylactic-co-glycolic acid (PLGA) nanoparticles have been used to increase the relative oral bioavailability of hydrophobic compounds and polyphenols in recent years, but the effects of the molecular weight of PLGA on bioavailability are still unknown. This study investigated the influence of polymer molecular weight on the relative oral bioavailability of curcumin, and explored the...
Pigs are believed to be one of the important sources of emerging human and swine influenza viruses (SwIV). Influenza virus conserved peptides have the potential to elicit cross-protective immune response, but without the help of potent adjuvant and delivery system they are poorly immunogenic. Biodegradable polylactic-co-glycolic acid (PLGA) nanoparticle (PLGA-NP) based vaccine delivery system e...
Background and Aims: Tissue engineering is a relatively novel field that has been intensely developing during recent years and has shown to be excessively promising when used for cartilage regeneration. Scaffolds represent important components for tissue engineering. Materials and Methods: The Poly Lactic-Co-Glycolic Acid (PLGA) impregnated with fibrin and hyaluronic acid (HA) produce hybrid s...
Abstract Sepsis, a life-threatening organ dysfunction induced by severe infection and uncontrolled host immune response, threatens the health of people all over world. Herein, type nanoparticle formulation with simple components is synthesized encapsulating monophosphoryl lipid A (MPLA), TLR4 agonist, poly(lactic-co-glycolic acid) (PLGA) nanoparticle. The obtained nanoparticles (MPLA@PLGA) coul...
BACKGROUND The therapeutic strategies for malignant melanoma are still cancer chemotherapy, radiotherapy, and tumor resection. However, these therapeutic strategies often lead to a reduced neutrophilic granulocyte count or loss of more blood after surgical tumor resection. In this study, we developed a formulation of hemostatic gauze impregnated with sustained-release granulocyte colony-stimula...
We describe a general method for incorporating target ligands into the surface of biocompatible polyester poly(lactic-co-glycolic acid) (PLGA) 50/50 materials using fatty acids. Avidin-fatty acid conjugates were prepared and efficiently incorporated into PLGA. Avidin was chosen as an adaptor protein to facilitate the attachment of a variety of biotinylated ligands. We show that fatty acid prefe...
Bone marrow mesenchymal stem cells (MSCs) are promising candidates for cell therapy and tissue engineering. We used mesenchymal stem cells from human bone marrow (hMSCs) as the seeding cells to investigate the potential of hepatocytic differentiation of hMSCs in porous polylactic glycolic acid (PLGA) scaffolds under perfusion induction. hMSCs were seeded and proliferated in PLGA scaffolds, and ...
Targeted drug delivery to endothelial cells lining the vasculature can improve treatment of many pathologies. Intercellular adhesion molecule-1 (ICAM-1), a transmembrane glycoprotein overexpressed in many diseases, is a good determinant for endothelial targeting of drug nanoparticles (NPs). In this study we synthesized surfactant-free, FITC-labeled poly(lactic-co-glycolic) acid (PLGA) NPs coate...
