As the inflammatory enzyme myeloperoxidase (MPO) is abundant in ruptured human atherosclerotic plaques, we aimed to investigate role of MPO as a potential diagnostic and therapeutic target for high-risk plaque.We employed tandem stenosis model plaque instability apolipoprotein E gene knockout (Apoe-/-) mice. To test MPO, used Mpo-/-Apoe-/- mice 2-thioxanthine inhibitor AZM198. In vivo activity was assessed by liquid chromatography-tandem mass spectrometry detection 2-chloroethidium...
Vascular smooth muscle cells (VSMCs) contribute dynamically to atherosclerosis at all stages but the molecular drivers of their phenotypic switching, especially during early plaque development, and how they progression remain unclear. We performed spatial transcriptomics on 12 human aortic tissues with without atherosclerotic plaque. Macrophage-like SMCs were predominant cell-type in atheroma, displaying high iron storage dysregulation, confirmed by elemental mapping nuclear microscopy. The...
The uptake of rare earth elements (REEs) such as Nd 3+ , Gd and Er by Euglena gracilis 848 algae cells has been studied using nuclear microprobe techniques at the Centre for Ion Beam Applications (CIBA), National University Singapore. cell imaging facility recently constructed CIBA allows scanning transmission ion microscopy (STIM) down to sub‐100‐nm level provides energy loss images whole intact cells. Helical coiling pellicle strips was observed, Rutherford backscattering spectrometry...
Changsha kiln ware represents an important status in the history of Chinese ceramics, well-known for its massive production capacity evidenced from extensive archaeological finds both domestically and abroad. It is long known or assumed that pioneer underglaze painted porcelains, however recent analytical studies suggest otherwise: overglaze, atypical underglaze, cannot be ascertained microscopically. glazing technique remains a convoluted issue debatable amongst scholars yet to concluded....
Abstract All clinically-approved and many novel gadolinium (Gd)-based contrast agents used to enhance signal intensity in magnetic resonance imaging (MRI) are optically silent. To verify MRI results, a “gold standard” that can map quantify Gd down the parts per million (ppm) levels is required. Nuclear microscopy relatively new technique has this capability composed of combination three ion beam techniques: scanning transmission microscopy, Rutherford backscattering spectrometry, particle...
