Ferroelectricity and Related Properties of Nitratecadmate(II) Hybrid with Metal-Vacancy.

All crystals are not ideal, and many of their properties are often determined not by the regular arrangement of atoms, but by the irregular arrangement of crystal defects. Many properties of materials can be controlled effectively by proper use of solid defects. By substitution of NH ion of a hexagonal perovskite structure (H dabco)(NH )(NO ) (dabco=1,4-diazabicyclo[2.

[Quantitative analysis of gene expression in infected with and gene expression in various tissues].

Objective: To investigate the expression of some genes in infected with , so as to provide insight into the preliminary understanding of the interactions between and its intermediate host .

Methods: was fed with rat faces containing the first-stage larvae of . Three to five was sampled 1, 10 days and 20 days after feeding, and the hemolymph, hepatopancreas, kidney, intestinal tract, head-foot and gill tissues were collected, while uninfected served as controls.

[Study on allele mutation of in Zichuan District, Zibo City, Shandong Province].

Objective: To study the seasonal dynamics of and the distribution of knockdown resistance () gene related sodium channel gene polymorphism in Zichuan District, Zibo City, Shandong Province.

Methods: mosquitoes were collected in Zichuan District during the peak period of mosquito vector activity from 2017 to 2018. The DNA from was extracted, and the genotypes and frequencies of allele mutation were detected by polymerase chain reaction.

Staphylococcal enterotoxin B administration during pregnancy imprints the increased CD4:CD8 T-cell ratio in the peripheral blood from neonatal to adult offspring rats.

Our previous study demonstrated that Staphylococcal enterotoxin B (SEB) administration during pregnancy could alter the percentage of T cells subpopulation in the thymus of the neonatal rats; however, little is known about the effect of maternal SEB administration during pregnancy on T cells subpopulation in the peripheral blood of the offspring rats. In the present study, pregnant rats at gestational day 16 were intravenously injected with 15 µg SEB. The present study found that prenatal exposure to SEB significantly decreased the percentages of CD8 T cells in the peripheral blood of both neonatal rats on the fifth day after delivery and the adult offspring rats.
