BACKGROUND Ovarian cancer is the most leading cause of death and the third most common gynecologic malignancy in women. Traditional chemotherapy has inevitable drawbacks of nonspecific tumor targeting, high toxicity, and poor therapeutic efficiency. In order to overcome such shortcomings, we prepared a novel nano-carrier drug-delivery system to enhance the anti-tumor efficiency. METHODS In vi...

Multifunctional nanocarriers for pathological site imaging and regulated drug delivery are increasingly promising for disease diagnosis and treatment. We developed a multifunctional theranostic nanocarrier system for anticancer drug delivery and molecular imaging. Superparamagnetic iron oxide nanoparticles (SPIONs) as an MRI contrast agent and busulphan as an antineoplastic agent were encapsula...

SPIONs are composed of Fe3O4 or gamma Fe2O3 cores and a biocompatible shell from Dextran, PLA, PEG, Chitosan, PVA. have many important applications in medicine biology such as cell sorting, drug carrier, magnetic hyperthermia, resonance imaging (MRI). This study aims to check the ability copolymer PLA-PEG coated ferromagnetic nanosystems (Fe3O4@PLA-PEG) produced for MRI application. The results...

BACKGROUND Chemotherapeutic drugs used for cancer therapy frequently encounter multiple-drug resistance (MDR). Nanoscale carriers that can target tumors to accumulate and release drugs intracellularly have the greatest potential for overcoming MDR. Glucose transporter-1 (GLUT-1) and glutathione (GSH) overexpression in cancer cells was exploited to assemble aminoglucose (AG)-conjugated, redox-re...

Therapeutic effect of glioma is often limited due to low permeability of delivery systems across the Blood-Brain Barrier (BBB) and poor penetration into the tumor tissue. In order to overcome the two barriers, we proposed Angiopep-conjugated PEG-PCL nanoparticles (ANG-PEG-NP) as a dual targeting drug delivery system for glioma treatment basing on low density lipoprotein receptor related protein...

BACKGROUND Multifunctional nanocarriers for controlled drug delivery, imaging of disease development and follow-up of treatment efficacy are promising novel tools for disease diagnosis and treatment. In the current investigation, we present a multifunctional theranostic nanocarrier system for anticancer drug delivery and molecular imaging. Superparamagnetic iron oxide nanoparticles (SPIONs) as ...

Epidural scar formation after laminectomy impede surgical outcomes of decompression. Mitomycin C (MMC) has been demonstrated to have significant inhibitory effects on epidural scar. This study was undertaken to develop an effective MMC controlled‑release membrane and to investigate its effects on epidural scar in rat models of laminectomy. A total of 72 rats that underwent laminectomy were divi...

Our goal was to evaluate the potential health risk of the polymeric NP, poly(ethylene glycol)-block-poly(lactic acid) (PEG-b-PLA), from the view of redox imbalance of the organism in two different life stages. Female Wistar rats were neonatally administered intraperitoneally with PEG-b-PLA NPs [20 mg/kg of b.w. (PEG20) or 40 (PEG40) mg/kg of b.w.] from postnatal day 4 (PND4) to PND7. We measure...
