Polydopamine-functionalized selenium nanoparticles as an efficient photoresponsive antibacterial platform.

A photoresponsive therapeutic antibacterial platform was designed and constructed using polydopamine-functionalized selenium nanoparticles as a carrier loaded with indocyanine green (Se@PDA-ICG). The therapeutic platform was confirmed by characterization and the antibacterial activity of Se@PDA-ICG against () and () was investigated. Under 808 nm laser irradiation, the antibacterial rate of Se@PDA-ICG against and was 100% at 125 μg mL.

Porous graphitic carbon nitride with high concentration of oxygen promotes photocatalytic H evolution.

Porous structure design and the content regulation of heteroelements have been proved to be effective strategies to boost photocatalytic H generation activity of graphitic carbon nitride (g-CN) based photocatalyst. Herein, a series of porous graphitic carbon nitride with high concentration of oxygen (g-CN-O) photocatalysts were synthesized polymerization process using colloidal SiO as oxygen source. The content of oxygen within the g-CN-O photocatalysts could be tuned by adjusting the amount of added colloidal SiO during the preparation procedure.

Enhancing the antivirus activity of chimeric canine interferon with ricin subunit B by using nanoparticle formulations.

Despite interferon alpha having a broad spectrum of antiviral activity and strong antiproliferative activity, its applications are severely limited due to the intrinsic properties of proteins, such as poor stability and short serum half-life. In our study, canine interferon alpha () gene was fused with the ricin toxin B chain () to form /, which encodes a 463-amino acid protein containing a 15-amino acid encoded (GS) flexible linker. After expression in prokaryote, purification and renaturation, the cytotoxicity and antiviral activity of rCaIFNα/RTB were investigated in Madin-Darby canine kidney (MDCK) cells.

[Study on Ranunculaceae herbal decoction pieces using X-ray diffraction].

The powder X-ray diffraction(PXRD) technique was used to investigate fourteen kinds of Ranunculaceae herbal decoction pieces(RHDP) recorded in Chinese Pharmacopoeia and to explore a novel PXRD quality control method for RHDP. The results indicated that only three RHDP-Paeoniae Radix Alba, Paeoniae Radix Rubra, and Moutan Cortex, contained calcium oxalate monodydrate(COM), whereas no COM existed in other eleven kinds of RHDP. The difference in PXRD for Paeoniae Radix Alba and Paeoniae Radix Rubra from different growing areas were investigated.

Identification and characterization of a T-2 toxin-producing strain and the anti-tumor effect of the T-2 toxin on human hepatoma cell line SMMC-7721.

T-2 toxin, produced by moulds, is a type A trichothecene mycotoxin which is known to inhibit protein synthesis and also reported to induce DNA lesions, potentially causing DNA fragmentation. T-2 toxin is a very potent cytotoxic toxin, which displays anti-tumor properties. Nevertheless, more studies are still needed to explore its antitumor mechanisms as well as its clinical application in cancer treatment.

Dihydroartemisinin induces apoptosis and downregulates glucose metabolism in JF-305 pancreatic cancer cells.

Cancer cell promotion of glycolysis provides a promising therapeutic target for cancer treatment. Dihydroartemisinin (DHA) displays cytotoxicity to multiple human tumor cells. However, its effects on pancreatic cancer cells are not well studied.

Bisphenol a influences blastocyst implantation via regulating integrin β3 and trophinin expression levels.

Objective: This study is to investigate effects of bisphenol A (BPA) on the blastocyst implantation in endometrium.

Methods: Pregnant mice were orally administered with BPA. Implantation sites were examined, and serum estrogen level was assayed with ELISA.

Nitric oxide regulates blastocyst hatching in mice.

Objective: This study is to determine the regulatory role of nitric oxide in mouse blastocyst hatching.

Methods: Kunming female mice were superovulated and then mated with mature male mice. On day 2.
