TL;DR: RLPs upregulated endothelial expression of ICAM-1, VCAM- 1, and TF, proatherothrombogenic molecules, partly through a redox-sensitive mechanism, and may have an important role in atherothROMbotic complications in hypertriglyceridemic patients.
Abstract: Background—Triglyceride-rich lipoproteins (TGLs) are atherogenic. However, their cellular mechanisms remain largely unexplained. This study examined the effects of isolated remnant-like lipoprotein...

TL;DR: OFL concentrations in wastewater effluents measured in this study were approximately 1-2 orders of magnitude lower than the EC50 concentrations for environmental bacterium, however, greater concentrations of other QAs in sewage sludge from WWTPs may result in cumulative effects.

TL;DR: Comparison of organochlorine concentrations in fishes collected from Lake Tai and Hangzhou Bay suggests the presence of local sources of HCHs, chlordanes and PCBs at Lake Tai, and higher proportions of penta- and hexa-PCB congeners in fishes at LakeTai may suggest the use of highly chlorinated PCB product around this lake.

TL;DR: Results suggest that OAT3 mediates the brain‐to‐blood transport of indoxyl sulfate, and is also involved in the efflux transport of neurotransmitter metabolites and drugs in the brain.
Abstract: Renal impairment is associated with CNS dysfunctions and the accumulation of uremic toxins, such as indoxyl sulfate, in blood. To evaluate the relevance of indoxyl sulfate to CNS dysfunctions, we investigated the brain-to-blood transport of indoxyl sulfate at the blood-brain barrier (BBB) using the Brain Efflux Index method. [(3)H]Indoxyl sulfate undergoes efflux transport with an efflux transport rate of 1.08 x 10(-2)/min, and the process is saturable with a Km of 298 microm. This process is inhibited by para-aminohippuric acid, probenecid, benzylpenicillin, cimetidine and uremic toxinins, such as hippuric acid and 3-carboxy-4-methyl-5-propyl-2-furanpropanoic acid. RT-PCR revealed that an OAT3 mRNA is expressed in conditionally immortalized rat brain capillary endothelial cell lines and rat brain capillary fraction. Xenopus oocytes expressing OAT3 were found to exhibit [(3)H]indoxyl sulfate uptake, which was significantly inhibited by neurotransmitter metabolites, such as homovanillic acid and 3-methoxy-4-hydroxymandelic acid, and by acyclovir, cefazolin, baclofen, 6-mercaptopurine, benzoic acid, and ketoprofen. These results suggest that OAT3 mediates the brain-to-blood transport of indoxyl sulfate, and is also involved in the efflux transport of neurotransmitter metabolites and drugs. Therefore, inhibition of the brain-to-blood transport involving OAT3 would occur in uremia and lead to the accumulation of neurotransmitter metabolites and drugs in the brain.

TL;DR: Results demonstrate that the HBV genome integrated into the mouse chromosome acted as a template for viral gene expression, allowing viral replication, and should be useful for detailed studies of the replication and expression of HBV and for pathological studies of hepatitis, including the development of hepatocellular carcinoma.
Abstract: We produced transgenic mice by microinjecting a partial tandem duplication of the complete hepatitis B virus (HBV) genome into fertilized eggs of C57BL/6 mice. One of eight transgenic mice was a high producer for HBV surface antigen (HBsAg) and HBV e antigen (HBeAg) in the serum. The HBV genomes were transmitted to the next generation and these F1 mice also produced HBsAg and HBeAg. mRNAs of 3.5, 2.1, and 0.8 kilobases were detected in the livers and the kidneys of these mice. In addition, a 0.8-kilobase RNA was detected in the testis. Single-stranded and partially double-stranded HBV DNAs were shown to be produced in the cytoplasm of the liver and kidneys. These HBV DNAs were associated with the core particles, indistinguishable from nucleocapsid produced in an infected human liver. Viral genome DNA was detected in the serum. These results demonstrate that the HBV genome integrated into the mouse chromosome acted as a template for viral gene expression, allowing viral replication. Thus, these transgenic mice should be useful for detailed studies of the replication and expression of HBV and for pathological studies of hepatitis, including the development of hepatocellular carcinoma.
