The endoplasmic reticulum stress inducer thapsigargin enhances the toxicity of ZnO nanoparticles to macrophages and macrophage-endothelial co-culture
In this study, the effects of ER stress inducer thapsigargin (TG) on the toxicity of ZnO NPs to THP-1 macrophages were investigated. The results showed that TG enhanced ZnO NP induced cytotoxicity as revealed by water soluble tetrazolium-1 (WST-1) and neutral red uptake assays, but not lactate dehydrogenase (LDH) assay. ZnO NPs dose-dependently enhanced the accumulation of intracellular Zn ions without the induction of reactive oxygen species (ROS), and the presence of TG did not significantly affect these effects. In the co-culture, exposure of THP-1 macrophages in the upper chamber to ZnO NPs and TG significantly reduced the viability of human umbilical vein endothelial cells (HUVECs) in the lower chamber, but the release of tumor necrosis factor α (TNFα) was not induced. In summary, our data showed that stressing THP-1 macrophages with TG enhanced the cytotoxicity of ZnO NPs to macrophages and macrophage-endothelial co-cultures. Graphical abstract

Hence, health insurance coverage could affect financial risk-taking by offsetting health-related background risk. We use a regression discontinuity design to examine whether Medicare eligibility at age 65 increases stockholding in the US and find that it does so for those with college educa...
In this study, serum IL6 was measured by ELISA, and the HSD11B1rs12086634(T/G) polymorphism was analyzed using a TaqMan allelic discrimination assay technique. There were statistically significant differences between the two studied groups concerning the serum IL-6 level and HSD11B1rs12086634(T/G) genotype distribution, with increased serum IL6 and increased frequencies of the GG and TG genotypes in patients with PCO. The GG genotype of HSD11B1 rs12086634(T/G) and its associated high level of serum IL-6 may represent genetic risk factors for PCOS.

ConclusionThe CFQL-2 is a brief, reliable scale that effectively measures psychosocial aspects of QoL and is sensitive to changes in QoL in families of children with ASD or related neurodevelopmental disorders. Child externalizing behavior is strongly associated with reductions in multiple aspects of child and family psychosocial QoL.
ConclusionThis meta-analysis suggested a significant association between MTHFR gene polymorphism (C677T and A1298C) and ASD risk.
ConclusionGiven that obtaining negative margins is important in reducing the risk of recurrence, the method of surgical resection utilized is based on the amount of future functional residual hepatic parenchyma.
ConclusionsTattooing of axillary LNs is safe and easily performed. Tattooing was helpful in identifying the marked LN in the majority of cases. This technique helps to ensure that metastatic LNs are identified and removed at surgery after NAT.
