Preparation and Properties of 3D Printing Light-Curable Resin Modified with Hyperbranched Polysiloxane.

A novel, hyperbranched polysiloxane (HBPSi) is successfully synthesized via hydrolysis using γ-methacryloxypropyl trimethoxysilane (A174) and deionized water, under catalyst-free conditions. Then, for the first time, the HBPSis are used to modify a 3D printing light-curing epoxy resin. Thermogravimetry results showed that the addition of HBPSi improved the heat resistance of the epoxy resin.

Enhancement of Electrochemical Performance of LiFePO@C by Ga Coating.

LiFePO (LFP) is one of the cathode materials widely used in lithium ion batteries at present, but its electronic conductivity is still unsatisfactory, which will affect its electrochemical performance. Ga-coated LiFePO@C (LFP@C) samples were prepared by a hydrothermal method and ultrasonic dispersion technology. Ga has good electrical conductivity and can rapidly conduct electrons within the LFP cathode material under the synergistic effect with C coating, thus improving the dynamic performance of the LFP cathode material.

Nasal administration of interleukin-33 induces airways angiogenesis and expression of multiple angiogenic factors in a murine asthma surrogate.

The T-helper cell type 2-promoting cytokine interleukin-33 (IL-33) has been implicated in asthma pathogenesis. Angiogenesis is a feature of airways remodelling in asthma. We hypothesized that IL-33 induces airways angiogenesis and expression of angiogenic factors in an established murine surrogate of asthma.

[Separations of four groups of analogues on cyclofructan based columns].

The separations of the immunosuppressive reagents, capsaicinoids, vitamin E, curcumins on cyclofructan based stationary phases containing polystyrene supported native cyclofructan (MCI Gel CRS100), silica supported native cyclofructan (Frulic N), silica supported isopropyl carbamate cyclofructan 6 (Larihc P), silica supported R-naphthylethyl carbamate cyclofructan 6 (Larihc RN) in normal phase HPLC mode were studied. From the investigation it showed that the column MCI Gel CRS100 was more suitable for the separation in normal phase than in hydrophilic interaction liquid chromatography. Derivatized cyclofructan stationary phases, Larihc P and Larihc RN, showed better selectivities in comparison with the native cyclofructan stationary phases.

Ginkgolide B produced endophytic fungus (Fusarium oxysporum) isolated from Ginkgo biloba.

To screen the presence of ginkgolide B-producing endophytic fungi from the root bark of Ginkgo biloba, a total of 27 fungal isolates, belonging to 6 different genus, were isolated from the internal root bark of the plant Ginkgo biloba. The fungal isolates were fermented on solid media and their metabolites were analyzed by TLC. The obtained potential ginkgolides-producing fungus, the isolate SYP0056 which was identified as Fusarium oxysporum, was successively cultured in the liquid fermentation media, and its metabolite was analyzed by HPLC.
