The healing of bone defects after a fracture remains key issue to be addressed. Globally, more than 20 million patients experience annually. Among all artificial repair materials that can aid healing, implantable scaffolds made from mineralized collagen (MC) base have the strongest bionic properties. MC/PLGA scaffold, created by adding Poly (lactic-co-glycolic acid) copolymer (PLGA) and magnesi...

PURPOSE To reduce the adverse effects and high frequency of administration of propranolol to treat infantile hemangioma, we first utilized propranolol-loaded liposomes-in-microsphere (PLIM) as a novel topical release system to realize sustained release of propranolol. METHODS PLIM was developed from encapsulating propranolol-loaded liposomes (PLs) in microspheres made of poly(lactic-co-glycol...

Poly(lactic-co-glycolic acid) (PLGA) is a strong candidate for being a drug carrier in drug delivery systems because of its biocompatibility and biodegradability. However, in degrading PLGA matrices, the encapsulated peptide and protein drugs can undergo various degradation reactions, including deamidation at asparagine (Asn) residues to give a succinimide species, which may affect their potenc...

In this study, we investigate the fabrication of 3D porous poly(lactic-co-glycolic acid) (PLGA) scaffolds using the thermally-induced phase separation technique. The current study focuses on the selection of alternative solvents for this process using a number of criteria, including predicted solubility, toxicity, removability and processability. Solvents were removed via either vacuum freeze-d...

Poly(lactic acid) (PLA) and poly(lactic-coGA) (PLGA) with low molecular weights were synthesized by a one-step polycondensation of lactic acid (LA) with glycolic acid (GA) molecules using stannous octoate as a catalyst at 160°C. A high yield ( 80%) of all the polymers was obtained in the study. The PLA and PLGA copolymers were characterized by H-NMR, GPC, and DSC measurements, etc. We elaborate...

Zaleplon (ZP) is a sedative and hypnotic drug used for the treatment of insomnia. Despite its potent anticonvulsant activity, ZP not commonly convulsion since characterized by low oral bioavailability as result poor solubility extensive liver metabolism. The following study aimed to formulate specifically controlled release nano-vehicles parenteral delivery enhance biological activity. A modifi...

Targeted delivery and smart response of nanomedicine hold great promise for improving the therapeutic efficacy alleviating side effects chemotherapy agents in cancer treatment. However, availability only a few studies that discuss organic nanomedicines with these properties limits development prospects nanomedicines. In present study, folic acid (FA)-targeted glutathione (GSH) responsive were r...

Fungal infections are an important cause of morbidity and mortality in immunocompromised patients. Amphotericin B (AMB), with broad-spectrum antifungal activity, has long been recognized as a powerful fungicidal drug, but its clinical toxicities mainly nephrotoxicity and poor solubility limit its wide application in clinical practice. The fungal metabolism along with the host immune response us...

Inhalable glycol chitosan-coated poly(lactic-co-glycolic acid) (PLGA) nanoparticles containing palmitic acid-modified exendin-4 (Pal-Ex4) (chitosan Pal-Ex4 PLGA NPs) were prepared and characterized. The surface morphology, particle size, and zeta potential of chitosan Pal-Ex4 PLGA NPs were investigated, and the adsorption and cytotoxicity of chitosan Pal-Ex4 PLGA NPs were evaluated in human lun...
