Objective: Embryonic interferon-tau (IFNT) and progesterone affect expression of interferonstimulated genes (ISGs), progesterone receptor (PGR) and progesterone-induced blocking factor (PIBF) in the ovine thyroid.Methods: Thyroids of ewes were sampled at day 16 of nonpregnancy, days 13, 16, and 25 of pregnancy, and real-time quantitative polymerase chain reaction assay, western blot and immunohistochemistry were used to detect expression of ISGs, PGR, and PIBF.Results: Free ISG15 protein was undetected, but ISG15 conjugated proteins upregulated at day 16 of pregnancy, and expression levels of ISG15 conjugated proteins, PGR isoform (70 kDa), PIBF, interferon-gamma-inducible protein 10 and myxovirusresistance protein 1 peaked, but expression level of signal transducer and activator of transcription 1 was the lowest at day 16 of pregnancy. In addition, the expression levels of PGR isoform (70 kDa) and signal transducer and activator of transcription 1 (STAT1) decreased, but levels of PGR isoform (43 kDa), 2',5'-oligoadenylate synthetase, IP-10 and MX1 increased at day 25 of pregnancy comparing with day 16 of the estrous cycle.Conclusion: Early pregnancy affects expression of ISGs, PGR, and PIBF in maternal thyroid through IFNT and progesterone, which may regulate thyroid autoimmunity and thyroid hormone secretion in ewes.

Synthesis of CdxZn1-xS@MIL-101(Cr) Composite Catalysts for the Photodegradation of Methylene Blue
Shipeng Yang,Siwei Peng,Chunhui Zhang,Xuwen He,Yaqi Cai 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2018 NANO Vol.13 No.10
Nanoparticles of the semiconductor catalyst CdxZn1-xS were embedded into the metal organic framework MIL-101(Cr) to obtain CdxZn1-xS@MIL-101(Cr) nanocomposites. These materials not only possess high surface areas and mesopores but also show good utilization of light energy. The ultraviolet-visible diffuse reflectance patterns of CdxZn1-xS@MIL-101(Cr) nanocomposites showed that Cd0.8Zn0.2S@MIL-101(Cr) possessed good visible light response ability among the synthesized nanocomposites. The photocatalytic performance of the CdxZn1-xS@MIL-101(Cr) nanocomposites were tested via degradation and mineralization of methylene blue in neutral water solution under light irradiation using a 300W xenon lamp. As a result, using Cd0.8Zn0.2S@MIL-101(Cr) as a catalyst, 99.2% of methylene blue was mineralized within 30 min. Due to the synergistic effect of adsorption by the MIL-101(Cr) component and photocatalytic degradation provided by the Cd0.8Zn0.2S component, the Cd0.8Zn0.2S@MIL-101(Cr) catalyst displayed superior photocatalytic performance relative to Cd0.8Zn0.2S and MIL-101(Cr). Furthermore, Cd0.8Zn0.2S@MIL-101(Cr) possessed excellent stability during photo-degradation and exhibited good reusability. The remarkable photocatalytic performance of Cd0.8Zn0.2S@MIL-101(Cr) is likely due to the effective transfer of electrons and holes at the heterojunction interfaces.
