Lipid accumulation in macrophages has profound effects on macrophage gene expression and contributes to the development of atherosclerosis. Here, we report that angiopoietin-like protein 4 (ANGPTL4) is the most highly upregulated gene in foamy macrophages and it's absence in haematopoietic cells results in larger atherosclerotic plaques, characterized by bigger necrotic core areas and increased...
The brass tubes with foam cores of AlSi7SiC3, AlSi7SiC3Fe1 and AlSi7SiC3Fe3 were produced as the crush-boxes with circle and square cross-section. Then axial compressive behavior and energy absorption capability of the foam-filled tubes were investigated during the quasi-static progressive plastic buckling. The uniaxial compressive stress–strain curves of the foam-filled brass tubes exhibited t...
Foam injection is widely applied in amounts of fields to drilling, production, and formation protection. Sometimes, the application result is disappointing, which is caused by the failure of bubble generation in foam flooding. Therefore, it is necessary to seek ways for improving the performance of foam injection. An increased disturbance to the stratum, like the vibration caused by a seismic o...
We report experimental studies of carbon nanofoam produced using a hydrothermal autoclave reactor with a sucrose solution and a small added amount of naphthalene. The foam has an average density of 85 mg/cc and is uniform in its appearance. He-ion microscopy (HeIM), Raman spectroscopy and X-ray photoelectron spectroscopy (XPS) were used to characterize the foam samples. These show good consiste...
Macrophages play a critical role throughout atherogenesis, from the initiating events leading to plaque formation to the development of plaque instability and thrombosis. Uptake of modified forms of low-density lipoprotein by macrophages within the arterial wall leads to their transition into arterial foam cells and the development of atherosclerotic plaques. In addition, as plaques mature and ...
The structures realized using sandwich technologies combine low weight with high energy absorbing capacity, so they are suitable for applications in the transport industry (automotive, aerospace, shipbuilding industry) where the “lightweight design” philosophy and the safety of vehicles are very important aspects. While sandwich structures with polymeric foams have been applied for many years, ...
Abstract Nominated for Eurosteel 2021 Best Paper Award The introduction to the market of metal foams represents a significant opportunity increase use in construction market. In fact, development new products made and steel could improve performance conventional buildings terms stiffness resistance. first structural applications these materials have already shown potential composites foam steel...
