Preparation of PDMS and PDMS-UiO-66 oxygen-rich membranes and modules for membrane-aerated biofilm reactors.

A membrane-aerated biofilm reactor (MABR) combines membrane technology with biofilm processes and has unique advantages in the treatment of organic wastewater and volatile wastewater. The common membranes for MABR systems usually have relatively uneven pore structures and low bubble point pressure, resulting in unsatisfactory O utilization and wastewater treatment efficiency. In this work, polydimethylsiloxane (PDMS) and UiO-66 (a Zr-based metal organic framework) were coated on the surface of a commercial polypropylene (PP) hollow fiber membrane to prepare oxygen-rich MABR membranes and modules, which showed an attractive O utilization rate and wastewater treatment efficiency.

Identification and characterization of Toll-like receptor 14d in Northeast Chinese lamprey ().

Toll-like receptors (TLRs) play an important role in innate immunity of defense against bacterial or viral pathogens. To study the biological characteristics and functions of the TLR genes, TLR14d was identified from Northeast Chinese lamprey () and named LmTLR14d. LmTLR14d coding sequence (cds) is 3285 bp in length and encodes 1094 amino acids (aa).

Identification and functional characterization of an immune adapter molecular TRIF in Northeast Chinese lamprey (Lethenteron morii).

The TIR domain-containing adaptor inducing IFN-β (TRIF) is an adaptor molecule that plays a critical role in the Toll-like receptors (TLRs)-mediated innate immune signaling pathway. Lamprey, as the most primitive jawless vertebrate, rely mainly on innate immunity to defend against various pathogens infection. The function of TRIF in lamprey remains unknown.

Northeast Chinese lamprey (Lethenteron morii) MyD88: Identification, expression, and functional characterization.

Myeloid differentiation factor 88 (MyD88) is a key adaptor of Toll-like receptors (TLR), an important pattern recognition receptor of the innate immune system. To study the origin and evolution of the vertebrate TLR signaling pathway in innate immune systems, we analyzed the biological characteristics and functions of the MyD88 gene in Northeast Chinese lamprey (Lethenteron morii) using PCR amplification, real-time PCR analysis, dual luciferase reporter gene assay, immunofluorescence assay, and other methods. Bioinformatics analysis showed that LmMyD88 has a modular structure consisting of Toll/IL-1R domain (TIR) and death domain (DD), which is typical of the MyD88 family.

Complete replication of hepatitis B virus and hepatitis C virus in a newly developed hepatoma cell line.

The absence of a robust cell culture system for hepatitis B virus (HBV) and hepatitis C virus (HCV) infection has limited the analysis of the virus lifecycle and drug discovery. We have established a hepatoma cell line, HLCZ01, the first cell line, to the authors' knowledge, supporting the entire lifecycle of both HBV and HCV. HBV surface antigen (HBsAg)-positive particles can be observed in the supernatant and the lumen of the endoplasmic reticulum of the cells via electron microscopy.

Effect of A-L tonic capsule on DNA content in rat experimental hepatocarcinogenesis.

The effects of A-L tonic capsule on DNA content in rat experimental hepatocarcinogenesis induced by diethylnitrosamine (DENA) were observed. The experimental rats were divided into 4 groups. With exception of group D in which the rats were only administered with DENA, the rats in the groups A, B, C were previously, simultaneously and subsequently fed with A-L tonic capsule respectively while they were administered with DENA.
