Mikroangiographische Untersuchungen verschiedener menschlicher Tumoren nach Transplantation auf thymusaplastische Nacktmäuse

1983

Zehn verschiedene humane Tumoren (zwei Weichteilsarkome, sieben Adenokarzinome des Dickdarms und Magens sowie ein Plattenepithelkarzinom der Lunge) wurden unter die Bauchhaut von thymusaplastischen Nacktmausen implantiert und nach Anwachsen uber mehrere Generationen transplantiert. Bei 40 Tieren wurden die resultierenden Tumoren mikroangiographisch und histologisch untersucht und unter Zugrundelegung der bekannten angiographischen Tumorkriterien klassifiziert. Hierbei fanden sich bei Transplantaten des selben Ursprungstumors immer gleichartige Gefasbilder. Die histologischen Bilder korrelierten gut mit den rontgenologischen Befunden. Die histologische Feinstruktur der Tumorgefase sowie die …

Bis-cyclohexyl-crown-ethers as allosteric carriers

1992

Abstract Several bis-cyclohexyl-crown-ethers have been synthesized and used as carriers for alkaline cations. These compounds should all show negative allosteric cooperativity, but only 1 exhibits an odd cation transport behavior across the liquid organic membranes.

Reaction-Diffusion Network For Geometric Multiscale High Speed Image Processing

2010

International audience; In the framework of heavy mid-level processing for high speed imaging, a nonlinear bi-dimensional network is proposed, allowing the implementation of active curve algorithms. Usually this efficient type of algorithm is prohibitive for real-time image processing due to its calculus charge and the inadequate structure for the use of serial or parallel architectures. Another kind of implementation philosophy is proposed here, by considering the active curve generated by a propagation phenomenon inspired from biological modeling. A programmable nonlinear reaction-diffusion system is proposed under front control and technological constraints. Geometric multiscale processin…
