One-Pot Hydrothermal Synthesis of g-C₃N₄/BiPO₄ Nanocomposites with Significant Photocatalytic Activity.

The g-C₃N₄/BiPO₄ composites have been successfully synthesized via a one-pot hydrothermal process, which can be used to degrade the organic dyes (rhodamine B and methylene blue) under simulated sunlight irradiation. X-ray diffraction (XRD), scanning electron microscope (SEM), UV-Vis diffuse reflectance spectra and Fourier transform infrared (FTIR) spectroscopy have been employed to characterize the samples. The g-C₃N₄/BiPO₄ composites exhibited higher photocatalytic activity than pure BiPO4.

Formation of CO bubbles in epoxy resin coatings: A DFT study.

The epoxy resin coating is a fundamental species with epoxy resins used as main components to form the final film. Unexpectedly, bulky CO bubbles that occasionally appeared during the curing process of epoxy resin coatings might destroy the final film properties. With an attempt to thoroughly understand the formation mechanism of CO bubbles and further propose countermeasures to control them, Density Function Theory (DFT) in this paper was employed to calculate the absorption process, the curing reaction and the formation mechanism of CO bubbles.

A novel ratiometric fluorescent sensor for Ag+ based on two fluorophores.

A novel ratiometric fluorescent probe BCB was reported for the first time for the sensitive and selective analysis of Ag based on two Boradiazaindacene (BODIPY) as both the reference fluorophore and recognition part. Upon the addition of Ag ions, a strong fluorescence emission at 570 nm from recognition BODIPY would be appeared, whereas the fluorescence of the other BODIPY at 535 nm would be a constant reference fluorescence signal. As a result, the ratio of fluorescence intensity (λ570/λ535) was changed from 0.

[Effect of soluble total proteins of Zaocys dumnades on interleukin-1beta, tumor necrosis factor-alpha and interleukin-10 expressions in human fibroblast-like synoviocytes in vitro].

Objective: To evaluate the effect of soluble total proteins of Zaocys dhumnades on the expressions of interleukin-1beta (IL-1beta), tumor necrosis factor-alpha (TNF-alpha) and IL-10 in human fibroblast-like synoviocytes (FLS) cultured in vitro.

Methods: Primary cultured FLS isolated from the synovium of patients with rheumatoid arthritis (RA) were incubated in the presence of different concentrations (50, 150 and 450 microg/ml) of soluble total proteins of Zaocys dhumnades, with Tripterygium hypoglaucum Hutch (THH) and DMEM as the positive and negative controls, respectively. Enzyme-linked immunosorbent assay (ELISA) and RT-PCR were used to detect the expressions of IL-1beta, IL-10 and TNF-alpha in the FLS.

[The effect of the type II collagen protein from Zaocys on cytokines production by synoviocytes in rats with adjuvant arthritis].

Objective: To investigate the effect of the type II collagen (C II) protein from Zaocys on cytokines production by synoviocytes in rats with adjuvant arthritis (AA).

Methods: Type II collagen protein was abstracted and purificated from Zaocys. Adjuvant arthritis (AA) was induced by a single intradermal injection of 0.

[Effect of raloxifene and estradiol on the biological function and osteoprotegerin expression of osteoblasts in vitro].

Objective: To study the effect of raloxifene and estradiol on the biological function and osteoprotegerin expression of osteoblasts in vitro.

Methods: Different doses of raloxifene and estradiol were added into the medium of the second generation osteoblasts from the shull of newborn SD rats. The proliferation, differentiation, mineralization and osteoprotegerin expression of the osteoblasts in different groups were observed.

[Biological effect of serum of kidney-tonifying traditional Chinese drug-fed rats on cultured osteoblasts].

Objective: To investigate the biological effects of the serum of rats fed with kidney-tonifying traditional Chinese drugs on cultured osteoblasts in vitro.

Methods: The culture media containing the serum from rats fed with the drugs at different doses (high, mediate and low doses) were used to treat the second passage of the osteoblasts from the skull of newborn SD rats, and the cell proliferation, differentiation and mineralization were observed.

Results: The serum stimulated the cell proliferation, enhanced alkaline phosphatase activity and increased the number of mineralized nodules in the cultured osteoblasts.
