β-Cyclodextrin Nanophotosensitizers for Redox-Sensitive Delivery of Chlorin e6.

The aim of this study is to prepare redox-sensitive nanophotosensitizers for the targeted delivery of chlorin e6 (Ce6) against cervical cancer. For this purpose, Ce6 was conjugated with β-cyclodextrin (bCD) via a disulfide bond, creating nanophotosensitizers that were fabricated for the redox-sensitive delivery of Ce6 against cancer cells. bCD was treated with succinic anhydride to synthesize succinylated bCD (bCDsu).

pH and Redox-Dual Sensitive Chitosan Nanoparticles Having Methyl Ester and Disulfide Linkages for Drug Targeting against Cholangiocarcinoma Cells.

The aim of this study is to prepare pH- and redox-sensitive nanoparticles for doxorubicin (DOX) delivery against DOX-resistant HuCC-T1 human cholangiocarcinoma (CCA) cells. For this purpose, L-histidine methyl ester (HIS) was attached to chitosan oligosaccharide (COS) via dithiodipropionic acid (abbreviated as ChitoHISss). DOX-incorporated nanoparticles of ChitoHISss conjugates were fabricated by a dialysis procedure.

Purpose: To analyze the anti-inflammatory and antioxidative effects of Camellia japonica (CJ) on human corneal epithelial (HCE) cells and its therapeutic effects in a mouse model of experimental dry eye (EDE).

Methods: Camellia japonica extracts of varying concentrations (0.001%, 0.

Ethosomes and Transfersomes for Topical Delivery of Ginsenoside Rhl from Red Ginseng: Characterization and In Vitro Evaluation.

Red ginseng (the steamed root of Panax ginseng C. A. Mayer), which contains ginsenosides as its main constituents, is frequently used to treat tumor, inflammation, diabetes, stress and acquired immunodeficiency syndrome in Asian countries.

660 nm Red LED Induces Secretory Leukocyte Protease Inhibitor (SLPI) in Lipopolysaccharide-Stimulated RAW264.7 Cell.

SLPI acts as a modulator of the innate immune responses of macrophages, neutrophils and odontoblasts, and LPS-inducible anti-inflammatory cytokine to suppress the production of pro-inflammatory products by macrophages. Many studies have revealed the effects of light emitting diodes (LEDs) on the tissue repair and inflammatory responses. Although the anti-inflammatory mechanisms of irradiation with LEDs in gingival fibroblasts are known, the effects of 660 nm red LEDs on the inflammation remain unclear.

Investigation on Sized-Regulated Iron Nanoparticles Prepared by Liquid Phase Plasma Reduction Process.

The liquid-phase plasma reduction method has been applied to prepare iron nanoparticles from iron chloride solution using a bipolar pulsed electrical discharge system. The excited states of atomic iron, hydrogen, and oxygen as well as the molecular bands of hydroxyl radicals were detected in the emission spectra. The iron nanoclusters formed at the initial stage convert to dispersion of small iron nanoparticles, which then grows slowly to form anisotropic, tetragonal shape.

Inhibitory Effects of Nano-Extract from Dendropanax morbifera on Proliferation and Migration of Vascular Smooth Muscle Cells.

The plant Dendropanax morbifera Léveille (D. morbifera), a subtropical broad-leaved evergreen tree, have been used in folk medicine for the treatment of infectious diseases, skin diseases, and other maladies. However, the effect of extracts from D.

Phytoncide, Nanochemicals from Chamaecyparis obtusa, Inhibits Proliferation and Migration of Vascular Smooth Muscle Cells.

Phytoncide, nanochemicals extracted from Chamaecyparis obtusa (C. obtusa), is reported to possess many pharmacological activities including immunological stimulating, anti-cancer, antioxidant, and antiinflammatory activities. However, the effect of phytoncide in vascuar diseases, especially on the behavior of vascular smooth muscle cells, has not yet been clearly elucidated.

Enhanced efficiency of dye-sensitized solar cells doped with green phosphors LaPO4:Ce, Tb or (Mg, Zn)Al11O19:Eu.

We have successfully introduced green phosphors LaPO4:Ce, Tb (G4) or (Mg, Zn)Al11O19:Eu (G2) into TiO2 photoelectrode of dye-sensitized solar cells. The conversion efficiency of the G4-doped device was enhanced by 30% compared with the pristine TiO2 photoelectrode. The green phosphor doped at 5-wt.

Enhanced efficiency of dye-sensitized solar cells with novel synthesized TiO2.

An anatase TiO2 and three kinds of novel TiO2 nanoparticles were prepared by a hydrothermal method for dye-sensitized solar cells (DSSCs), which were obtained by mixing NaOH (10 M), KOH (14 M) and LiOH (10 M) solution with an anatase TiO2 powder, respectively. The TiO2 working electrodes of DSSCs were prepared and the photoelectric properties of the cells were characterized. The influence of different poly(ethylene glycol) contents in TiO2 films with and without HNO3 treatment on the electron transfer in DSSCs were investigated.
