A Hybrid Syntactic Foam-Based Open-Cell Foam with Reversible Actuation
ACS Applied Materials & Interfaces, 2022Herein, we report the first hybrid open-cell foam with revisable actuation. Open-cell foams with revisable actuation are favoable for many applications. However, it is challenging to fabricate such open-cell foams with very low density. This study presents a novel concept of creating hybrid two-way (2W) shape memory open-cell foams using two-way shape ...

Macrophage foam cells and atherosclerosis
Frontiers in Bioscience, 2001Focal buildup of cholesterol in arteries is the process that produces atherosclerotic plaques, the cause of most coronary artery disease and strokes. Monocyte-derived macrophages are central cells that accumulate this cholesterol in atherosclerotic lesions, a manifestation of the scavenging function of the macrophage.

Foaming dynamics in Hele-Shaw cells
Physical Review E, 2006We have studied foaming dynamics in Hele-Shaw cells partially filled with a soap and water mixture. A series of upside-down flips produces an intermittent wetting of the cell and leads to foam formation. As a function of the number of flips, an increasing number of bubbles composes the foam, until saturation is observed. Statistical analysis shows that

Ultrastructure of Endometrial Stromal Foam Cells
American Journal of Clinical Pathology, 1979An endometrium with cystic-glandular hyperplasia contained large foam cells in the stroma. The majority had ultrastructural characteristics of endometrial stromal cells, although a few were interpreted as macrophages. Endometrial stromal cells that appeared normal by light microscopy contained varying quantities of lipid on ultrastructural examination,

Glomerular foam cells in kidney allograft
International Urology and Nephrology, 1978Foam cells are occasionally encountered in renal glomeruli in cases of nephrotic syndrome, however, they were not described so far in renal allografts. The authors found the glomerular foam cells in a cadaveric kidney transplant which survived 7 months after transplantation in a 35-year-old man.

Renal interstitial foam cells are macrophages
Histopathology, 1992Immunohistochemical studies on renal biopsies from eight patients with various types of glomerulonephritis showed that the interstitial foam cells belonged to the monocyte‐macrophage lineage. There was a strong association between hypercholesterolaemia and the presence of renal interstitial foam cells.

Immobilization of Cells on Polyurethane Foam
2006In this chapter, protocols and details for the immobilization of a model cell onto polyurethane foam carriers are provided in order to facilitate the use of such systems in laboratory or industrial reactors. Polyurethane foam has recently acquired great relevance as a carrier for its good mechanical properties, high porosity, and large adsorption ...

Multiple Juvenile Xanthogranulomas Without Foam Cells and Giant Cells
Pediatric Dermatology, 1993Abstract: A 4‐month‐old boy had numerous nodular lesions. Microscopic findings revealed a histtocytic proliferation without foam cells and giant cells. Immunohistochemical studies showed that the histiocytes belonged to the monocyte‐macrophage system and not to the Langerhans cell system.

Mammary ductal foam cells: Macrophage immunophenotype
Human Pathology, 1993Mammary ductal foam cells are present in normal breast tissue as well as in a number of breast diseases. Such foam cells tend to be in particular abundance with fibrocystic changes of the breast. Foam cells may appear within duct lumens or plastered in cohesive masses along duct walls, simulating an epithelial structure.
