Scale‐up of Streptomyces species cultivations based on the morphological response to the energy dissipation rate

open access: yesAIChE Journal, EarlyView.
Abstract Filamentous microorganisms exhibit complex morphologies that influence product formation and are affected by various bioprocess parameters. Consistent morphology is therefore essential for comparable results during scale‐up. This study investigates the scale‐up of Streptomyces species (Streptomyces spp.) cultivations from shake flasks to ...

Endometrial foam Cells

Acta Obstetricia et Gynecologica Scandinavica, 1983
Abstract. Four patients with endometrial foam cells are described. In one the endometrium was obtained after parturition. It showed decidua and endometritis, whereas in the second patient, who had received birth control medication in the past, the endometrium was proliferative.

Ultrastructure of foam cell nephropathy

Virchows Archiv Abteilung A Pathologische Anatomie, 1968
In our study of 1400 percutaneous renal biopsies we have found a new morphological type of renal change: a nephropathy with foam cells, seen in patients without any peculiar clinical characteristics. Two cases of this nephropathy are presented with similar light microscopic changes but widely different electron microscopic findings.

Proteomic Analysis of Foam Cells

2006
Foam cells are characteristic pathological cells in the lesions of atherosclerosis. Previous works have established macrophage-derived foam cell model to study the central role of the foam cells, and analyzed the protein expression profiles in foam cells.

A Hybrid Syntactic Foam-Based Open-Cell Foam with Reversible Actuation

ACS Applied Materials & Interfaces, 2022
Herein, 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, 2001
Focal 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, 2006
We 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, 1979
An 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, 1978
Foam 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.
