Although studies have shown that Urotensin II (UII) can induce cardiomyocyte hypertrophy and UII-induced cardiomyocyte hypertrophy model has been widely used for hypertrophy research, but its precise mechanism remains unknown. Recent researches have demonstrated that UII-induced cardiomyocyte hypertrophy has a relationship with the changes of intracellular(More)
AIMS Inflammation plays an important role in the neointima formation of grafted veins. However, the initiation of inflammation in grafted veins is still unclear. Here, we investigated the role and underlying mechanism of an innate immunity signalling protein, caspase-associated recruitment domain 9 (CARD9) in vein grafts in mice. METHODS AND RESULTS In(More)
Sustained inflammation is associated with pulmonary vascular remodeling and arterial hypertension (PAH). Serum–glucocorticoid regulated kinase 1 (SGK1) has been shown to participate in vascular remodeling, but its role in inflammation-associated PAH remains unknown. In this study, the importance of SGK1 expression and activation was investigated on(More)
Whether dendritic cell (DC) derived exosomes play a role in the progression of endothelial inflammation and atherosclerosis remains unclear. Using a transwell system and exosome release inhibitor GW4869, we demonstrated that mature DCs contributed to endothelial inflammation and exosomes were involved in the process. To further confirm this finding, we(More)
Mild hypothermia (MH) renders the hearts resistant to ischemia/reperfusion (IR) injury in animal experiments. Unexpectedly, this effect was not observed in recent clinical trials. The aged hearts in mice have been demonstrated to be more susceptible to IR injury. This study aimed to examine whether the cardioprotection of MH was abolished in aged mice.(More)
Novel penniform superstructures of BaWO4 nanowires have been successfully synthesized in catanionic reverse micelles by using a double-hydrophilic block copolymer as the directing agent. This synthetic method is very simple, mild, and controllable, and it provides a novel method for direct solution-growth of hierarchical nanostructures based on inorganic(More)
By using the surface and element specificity of soft x-ray magnetic dichroism we provide direct experimental evidence for two different types of interfacial uncompensated Fe moments in exchange biased Co/FeF2 bilayers. Some moments are pinned and coupled antiparallel to the ferromagnet (FM). They give rise to a positive exchange bias and vanish above T(N) =(More)
The exchange bias and magnetic anisotropies in a Co layer on a single-crystalline FeF2 film have been determined between 30 and 300 K. By postulating that the coupling between the ferromagnet and the antiferromagnet persists above the Néel temperature (T(N)) we develop a model that quantitatively describes the exchange bias and the anisotropies over the(More)
BACKGROUND Atherosclerosis is widely recognized as a complex inflammatory disease involving pathogenic immune response of T cells and antigen-presenting cells (APCs) such as dendritic cells (DCs) and macrophages. Accumulating evidence has revealed that mature DCs play critical roles in the differentiation of effector T cells into CD4+ T cells, which(More)
