Intrahepatic Cholestasis of Pregnancy Increases Inflammatory Susceptibility in Neonatal Offspring by Modulating Gut Microbiota.

Intrahepatic cholestasis of pregnancy (ICP) is a liver disease of pregnancy that is characterized by increased bile acid levels in maternal serum. Studies have shown that cholestatic pregnancy can result in long-term metabolic disturbances in the offspring. However, how ICP shapes the offspring's immunity and predisposition to inflammatory disorders at an early stage is unknown.

14-3-3 gene family in spotted sea bass (Lateolabrax maculatus): Genome-wide identification, phylogenetic analysis and expression profiles after salinity stress.

The tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation (14-3-3) proteins are a group of highly conserved homologous and heterologous proteins involved in a wild range of physiological processes, including the regulation of many molecular phenomena under different environmental salinities. In this study, we identified eleven 14-3-3 genes from the spotted sea bass (Lateolabrax maculatus) genome and transcriptomic databases and verified their identities by conducting phylogenetic, syntenic and gene structure analyses. The spotted sea bass 14-3-3 genes are highly conserved based on sequence alignment, conserved domains and motifs, and tertiary structural feature.

[Isolation, identification and lead adsorption study of lead-resistant Lactobacillus casei strains from feces of healthy newborns].

Objective: To isolate and identify lead-resistant Lactobacillus casei strains with lead adsorption ability from the stool of healthy newborns as a new source of bacteria for developing lead-eliminating food products.

Methods: MRS was used to isolate lead-resistant bacteria from the feces of 30 healthy and full-term neonates. A phylogenetic tree was constructed based on the morphological characteristics and 16S rRNA sequences of the isolated bacteria.

[Effect of Electroacupuncture Intervention on Expression of NR 2 B Subunit of NMDA Receptor in Amygdala during Morphine Withdrawal in Rats].

Objective: To observe the effect of electroacupuncture (EA) on the spatial learning-memory ability and the expression of NR 2 B subunit of NMDA receptor in the amygdala (AMG) in rats with morphine withdrawal.

Methods: A total of 40. SD rats were randomized into control, model, manual acupuncture and EA groups (n = 10 in each group).

Protection against Escherichia coli O157:H7 challenge by immunization of mice with purified Tir proteins.

Enterohemorrhagic Escherichia coli (EHEC) O157:H7 infections cause serious public health problems worldwide. The translocation intimin receptor (Tir) is responsible for adhesion and attaching and effacing lesions. In the current study, we used a mitomycin-treated mouse model to evaluate the efficacy of subcutaneous vs intranasal administration of the recombinant Tir as vaccine.

[Study on the allergens of shrimps and crabs].

Aim: To investigate the allergen composition in the species of shrimp and crab.

Methods: The main allergens of shrimps and crabs were analyzed by SDS-PAGE and Western blot assay.

Results: The molecule weight of main allergic protein in shrimps was near to 36 000, and the main allergic proteins in different kinds of crabs were about 29 000, 36 000, 66 000, 89 000 molecule weight.

[Study on Rotavirus detection by nucleic acid sequence based amplification].

Rotavirus is one of the major cause of the viral gastroenteritis throughout the world. A nucleic acid sequence-based amplification(NASBA) technique for the detection of rotavirus in faecal specimens was developed and compared to the RT-PCR technique. Primers were designed according to the high conserved region of VP7 gene.

[Study on rotavirus detection with single-tube seminested RT-PCR method in shellfish].

Being a foodborne virus, Rotavirus was often carried by shellfish. At the present, RT-PCR was the most effective method of Rotavirus detection in shellfish, but its sensitivity was low because of low levels of virus contamination and PCR inhibitors in shellfish. So contaminated shellfish experimentally in laboratory, and imitated the natural environment to concentrate Rotavirus, then detected by the developed single-tube seminested RT-PCR.
