Liver cancer is a leading cause of cancer deaths worldwide. The combination therapy of cytotoxic and chemosensitizing agents loaded in nanoparticles has been highlighted as an effective treatment for different cancers. However, such studies in liver cancer remain very limited. In our study, we aim to develop a novel lipid nanoparticles loaded with doxorubicin (DOX) (an effective drug for liver ...

Decomposition of transition-metal amidinates [M{MeC(NiPr)2} n ] [M(AMD) n ; M=MnII, FeII, CoII, NiII, n=2; CuI, n=1) induced by microwave heating in the ionic liquids (ILs) 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIm][BF4]), 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIm][PF6]), 1-butyl-3-methylimidazolium trifluoromethanesulfonate (triflate) ([BMIm][TfO]), and 1-butyl-3-methyl...

Dendritic cells (DCs) are potent professional antigen presenting cells (APC) that activate naïve T cells. Interaction of ICAM-1 and LFA-1 molecules on each cell is required for T cell conjugation to DCs, which leads to naïve CD4+ T cell activation and proliferation. Nanoparticles capable of blocking LFA-1/ICAM-1 interaction were studied as inhibitors of T cell conjugation to DCs. Primary DCs we...

Phthalocyanine-aggregated Pluronic nanoparticles were constructed as a novel type of near-infrared (NIR) absorber for photothermal therapy. Tiny nanoparticles (~ 60 nm, FPc NPs) were prepared by aqueous dispersion of phthalocyanine-aggregated self-assembled nanodomains that were phase-separated from the melt mixture with Pluronic. Under NIR laser irradiation, FPc NPs manifested robust heat gene...

Ferrite nanoparticles (F-NPs) can transform both cancer diagnostics and therapeutics. Superparamagnetic F-NPs exhibit high magnetic moment and susceptibility such that in presence of a static magnetic field transverse relaxation rate of water protons for MRI contrast is augmented to locate F-NPs (i.e., diagnostics) and exposed to an alternating magnetic field local temperature is increased to i...

In this study, a single intraperitoneal injection of erythropoietin (EPO) loaded oligochitosan nanoparticles (epo-NPs) (average diameter 266 nm) was investigated as a treatment for periventricular leukomalacia (PVL). Nanoparticles were fabricated using a gelation technology process. PVL rats models were prepared to examine the therapeutic efficacy of epo-NPs and analyze the mechanism by which e...

The synthesis of semiconductor nanoparticles is an expanding research area due to the potential applications in the development of nanotechnologies. Especially, biosynthesized nanoparticles have become an important branch of nanotechnology. In the present work, we describe a low-cost and simple procedure for biosynthesis of Zinc oxide nanoparticles (ZnO NPs) using Pyrus Pyrifolia leaf extract. ...

zno nps (zinc oxide nanoparticles) has generated significant scientific interest as a novel antibacterial and anticancer agent. since oxidative stress is a critical determinant of zno nps-induced damage, it is necessary to characterize their underlying mode of action. different structural and physicochemical properties of zno nps such as particle surface, size, shape, crystal structure, chemica...

The enhancement of the photocatalytic activity of TiO₂ nanoparticles (NPs), synthesized in the presence of a very small amount of magnetite (Fe₃O₄) nanoparticles, is here presented and discussed. From X-ray diffraction (XRD) and differential scanning calorimetry (DSC) analyses, the crystallinity of TiO₂ nanoparticles (NPs) seems to be affected by Fe₃O₄, acting as nano-seeds to improve the tetra...

This work has mainly investigated the influence of the solvent on the nanoparticles distribution in digestive ripening. The experiments suggested that the solvents played a key role in digestive ripening of Au nanoparticles (Au NPs). For the benzol solvents, the resulting size distribution of Au NPs was inversely related to the solvent polarity. It may be interpreted by the low Gibbs free energ...
